GAN review to be forthcoming. I'd appreciate it if you could hold any edits to the article while I'm reviewing it, which will probably take me a few days. I did a light copy edit of the article. If you disagree with any of my changes, we can discuss it as part of the review. – Reidgreg (talk) 03:29, 13 January 2022 (UTC)[reply]

I consider all your copy edits to be good. Before seeing this I did make a couple of quite minor and non controversial copy edits to improve reading clarity. CT55555 (talk) 15:20, 13 January 2022 (UTC)[reply]
This is taking me a bit longer than I expected. I'm about halfway through the sources, then I'll do a copyvio check and go through the images and a few other things. – Reidgreg (talk) 02:02, 21 January 2022 (UTC)[reply]
Thanks for the update. CT55555 (talk) 02:14, 21 January 2022 (UTC)[reply]
Okay, full review posted. It's on the long side; please receive it constructively. I've used a checkmark icon (Checked) for material which I verified; let me know if you have trouble seeing this or other icons and I'll find another way to mark them. Please continue any further general discussion in the section General discussion at the bottom. This is a bit long so take it a bit at a time. – Reidgreg (talk) 17:09, 23 January 2022 (UTC)[reply]
Second pass review now posted. – Reidgreg (talk) 03:46, 4 March 2022 (UTC)[reply]
Third pass was 18 April, fourth pass now posted. – Reidgreg (talk) 01:02, 6 May 2022 (UTC)[reply]
Fifth pass, all good. – Reidgreg (talk) 15:55, 13 June 2022 (UTC)[reply]

Layout

[edit]

I feel that layout is the most apparent issue with the article and one which should be tackled first. It is part of GA criteria 1b, adherence to MOS:LAYOUT. The specific problem is MOS:OVERSECTION which states Very short sections and subsections clutter an article with headings and inhibit the flow of the prose. Short paragraphs and single sentences generally do not warrant their own subheading. The article has about 42 body sections for 3260 words of text, with several sections only 1–3 sentences. Compare to the GA Somerset Coalfield which is of similar length with 20 body sections. Combining some of the sections would allow you to tackle the subject matter in larger chunks, allowing you to make it more concise and coherent. I also feel like some of the material could be reorganized a bit.

Specific suggestions:

  • Section Ancient history is speaking in geologic time, I feel that this section should be combined into the top of section Geology and mineralogy. (Also, ancient history usually refers to about 5000 years ago, not one billion years.)
Agreed. Done. 20:26, CT55555 (talk) 23 January 2022 (UTC)Checked
  • Cheddar granite, Cardiff plutonic complex and Faraday granite: I feel that these short sections would be better presented as a bulleted list (see 'Children' lists at MOS:EMBED).
Agreed. Done. CT55555 (talk) 20:27, 23 January 2022 (UTC)Checked[reply]
  • Section title Mining history before uranium was discovered (1886 to 1922) is rather long. Maybe change it to 'Early mining efforts'. I would tend to remove the year range from the section header but leave them in for now, they can always be removed later.
Agreed. Done, with years left in for now. Also I'm agreeable to remove then, I assume you'll consider that and give advice in the coming days. CT55555 (talk) 20:27, 23 January 2022 (UTC)Checked (This was moved to the top of section Gems and other resources.)[reply]
Towards the end of the review I removed them CT55555 (talk) 19:02, 30 January 2022 (UTC)Checked[reply]
  • Section Gems and other resources, at least the first and third subsections, could probably be incorporated into the early history. The gold rush part might be best first, as that brought interest, surveying, and infrastructure. (I'll make a specific suggestion under Prose, below.)
I agree. I've combined parts one and three. I've not moved it into history yet, I'm open to do so, I suggest I do this for now, see how it looks overall and I'll take your advice after I've done one pass at the review, I'm assuming I'll act on all comments and then you might give more advice. CT55555 (talk) 20:26, 23 January 2022 (UTC)[reply]
Have now brought the gold paragraph to the start of that section. CT55555 (talk) 19:02, 30 January 2022 (UTC) Checked[reply]
  • Discovery of uranium – I was wondering if some of the survey/discovery background and associated biographical information from the later sections on the mines might fit better here. Generally speaking, when the article first mentions a person or entity, it's good to give their names in full, with linking or acronyms if appropriate, and a bit of information to establish who or what they are. On the other hand, it might be better to keep the mine information together, especially if parts are ultimately going to be moved to other articles (see Breadth and Focus below).
All the old sources I've got seem to often never give anyone's full name. So many are just A. B. Smith etc. The red linked Arthur Shore, I expect to become blue soon, I'm waiting on AfC to approve Draft:Arthur_H._Shore and it's taking a long time. So basically I don't have full names for people. So that said, I'm not sure if there is anything else I can do here. Please tell me if I've missed something? CT55555 (talk) 20:26, 23 January 2022 (UTC)[reply]
Reading again, I think you wanted me to mention their profession, i.e. they are all prospectors, so I've added that in CT55555 (talk) 19:02, 30 January 2022 (UTC)Checked[reply]
  • Uranium mining (1952 to 1982) I would suggest expanding the little introductory text before the sections on each mine. The mine sections are fairly long, and in case the reader doesn't want to go through all of that, the introductory part could serve as a summary and also gather any common elements to avoid repetition. I would suggest also incorporating the year range into the text so that it isn't only in the header. Another way might be to have a little table to summarize some of the key information about the mines (perhaps years of operation, the name of the feature they are on [Cheddar, Cardiff, etc.] tons of ore processed, U3O8 produced). For the text, maybe something like: "Uranium mining operations in the Bancroft area were conducted at four sites, beginning in the early 1950s and concluding by 1982. Each of these used underground hard-rock mining methods to access and collect uranium ores from the surrounding granite and gneiss. The mines were:" All of this should be cited.
Edited in your proposed text, and cited it. I've started the table, I'll need to save things and make sure I get it all correct, I'll make sure it's right before sending you a signal to look. Should I add citations into the table? CT55555 (talk) 20:26, 23 January 2022 (UTC)Checked[reply]

:::Update: I've gone back to government sources to make sure the uranium ore/oxide states are correct. Note there is contradiction between the academic paper and the numbers in the paper are not credible, the government numbers are credible and official. So I'm confident in the numbers in the table. CT55555 (talk) 00:38, 24 January 2022 (UTC) [reply]

Table is done, it's cited, will need the metric<>imperial thing. I therefore didn't add a sentence to the start of each mine's section. CT55555 (talk) 19:02, 30 January 2022 (UTC)Checked[reply]
  • Mine sections – I feel that if we tighten up the prose (addressed below), we could probably do away with the subsection headers for each of the mines (e.g.: Bicroft mining operations, Bicroft mine geology). But let's take care of the other issues first and see if this seems necessary.
I'm open to that, assuming we'll come back to this issue. CT55555 (talk) 20:26, 23 January 2022 (UTC)[reply]
I think later in the review or your comments below you went back on this, so leaving it for now. CT55555 (talk) 19:02, 30 January 2022 (UTC) (okay, goodChecked)[reply]
  • The influence of global economics, politics and local infrastructure This heading is a bit long. Perhaps change it to 'Economic growth and collapse' or 'Economic effects'? Similarly with the second subsection which might be shortened to 'Decline in demand'.

::Have changed to "economic and political effects". I'm not sure it's the perfect title, but agree it's an improvement. Changed to "decline in demand" also. CT55555 (talk) 20:26, 23 January 2022 (UTC)[reply]

Have changed it to "Economic and political influence" CT55555 (talk) 19:02, 30 January 2022 (UTC)Checked[reply]
  • The legacy of uranium mining (1982 to present day) This header is a bit long. The article title is 'Uranium mining in the Bancroft area' so much of this can be assumed. I would shorten it to 'Legacy (1982–present)' and possibly cut the date range later.
    Have changed to "Mining legacy". Have left date for now, open to changing it later. CT55555 (talk) 20:26, 23 January 2022 (UTC)[reply]
    Have changed it to "Legacies" CT55555 (talk) 19:02, 30 January 2022 (UTC) Checked[reply]
    • Some of the subsections are quite short. I would suggest combining the first and second, the third and fourth. The fifth, health legacy, is quite a bit longer and might be moved out to its own L2 section.
  • I also feel that the image galleries might break up the flow of the text. Perhaps consider moving them to the end of their L4 sections (where the headers have four equal signs).
Have combined 1+2, 3+4, I feel that health needs to fit under "legacy" otherwise I need to name "legacy" something like "Non health legacy issues", which would be weird. Or do you have a suggestion? For now, leaving "health" under "legacy". CT55555 (talk) 20:26, 23 January 2022 (UTC)Checked[reply]

Referencing & verifiability

[edit]

I went through the references one by one, and was unable to verify a few things. In some cases the source material is quite long and you may be able to point out the relevant passages for me. In others better sources may be required or the material removed. In particular, the Wikipedia community has placed higher standards on sourcing for medical information than other subjects (WP:MEDRS). More on that below as I get toward the parts on miners' health.

  • Nila Reynolds, Bancroft: A Bonanza of Memories. Seems reliable enough, and not used for anything controversial. Assume good faith for offline source.
Thanks. I bought the book to write this. CT55555 (talk) 01:38, 24 January 2022 (UTC)[reply]
  • Raymond McDougall, "Mineral Highlights from Bancroft..." Rocks & Minerals, peer reviewed journal.Checked
  • A.S. Bayne, Report on Wilson Uranium Property..., professional report, used for quotation only.Checked
  • Canadian Institute for Radiation Safety "Radioactive and toxic waste from the Bancroft...". RSS. This pdf does not seem to be searchable, so page numbers would help (in {{rp}} following citations). Verified three citations in the article from page 12 of this source; I didn't spot the one from the lead, perhaps you can find that? Following I will note the parts in the article and in the source, for verification and to check for copyvio.
    See reply below, hope that addresses it? CT55555 (talk) 01:38, 24 January 2022 (UTC)[reply]
    I'm wondering if RSS means RSS (i.e. presumably bad) or Reliable Secondary Source (i.e. presumably good)? I'm assuming the later, and that RSS means good. CT55555 (talk) 19:02, 30 January 2022 (UTC)[reply]
    Yes, WP:Reliable secondary sources. Reliable in that they are expert and trustworthy, and secondary in that they are independent of the primary source and objective. This is somewhat a note to myself; if the source is not an RSS, then I'd have to be extra careful checking for neutrality and accuracy.
    • In Ontario, other than the Bancroft area, uranium is also found in mineable quantities around Elliot Lake and Agnew Lake. I did not spot this in the source.
      I swapped it for two searchable sources just to make everyone's life easier. Hope that's cool. CT55555 (talk) 01:38, 24 January 2022 (UTC)Checked[reply]
    • 1929–1931 attempts were made to extract radon from the uranium ore. is covered by page 12: "Various attempts to recover radium from the uranium ore were made in the 1920's and 1930's."
    • in the aftermath of World War II, global interest in mining uranium escalated also page 12: "Following World War II, there was considerable interest in the mining of uranium."
    • [in combination with another source] Madawaska Mines Limited was formed in 1975 and purchased the mine, as well as the Faraday Mine. Mining operations restarted in 1976 and continued until 1982. I did not spot this in the source.
      The info on Grehawk mine is (confusingly) in the paragraph titled Madawaska Mine. That's on page 12 if you follow the page numbering at the top of the page, or page 15 if you are using Acrobat PDF reader.CT55555 (talk) 01:38, 24 January 2022 (UTC)Checked[reply]
    • The Atomic Energy Control Board (AECB) issued licenses for uranium mines and mills in Canada, and began regulating uranium mines in 1977. As a result of this, mines that closed prior to 1977 (i.e. Bicroft and Dyno Mines) were able to abandon the sites without any regulatory oversight. Faraday Mine/Madawaska Mine and Greyhawk Mine both resumed mining from 1976 until 1982, so their operation and closure had AECB oversight. also page 12: "Although these mines were licensed by the Atomic Energy Control Board of Canada (a Federal agency), the Atomic Energy Control Board did not regulate the operations of the uranium mining industry directly until 1977. [pp] Consequently, two of the uranium mines (Bicroft and Dyno) which ceased operations in the 1960's were allowed to abandon their mining and milling operations without any effort being made to minimize the radiation hazards emanating from the abandoned wastes. [pp] The other two uranium mines in the Bancroft area (Faraday and Greyhawk) were also abandoned int the 1960's but reactivated in 1976 by Madawaska Mines Ltd. That mining operation ceased in 1982."
  • Bancroft Historical Timeline This does not appear to be the town website. It says "We are a privately owned and operated website built by the community; for the community." It accepts advertisers and has a mission "to promote local tourism and business development". This may not be a reliable source. It is used for the following statement:
    • As a result of the uranium mining at four mine sites throughout the 1950s, Bancroft experienced rapid population and economic growth. Not verified by this source but will assume it is covered by the offline source also cited; I think a number of the other sources in the article could be used. I would suggest removing this reference from the article.
I've removed it, it's clearly covered in the book, citation 1. CheckedAGF
  • Canadian Deposits of Uranium and Thorium Griffith, Geological Survey of Canada. High-quality source. About 20 citations to this 357-page report. Although not required at GA, it might not be bad to add page numbers.
    I've never done the page number thing before, so I'll wait for your signal if the way I did it before was correct before doing this. CT55555 (talk) 01:38, 24 January 2022 (UTC)[reply]
    I tried the page numbering thing on another article I wrote, but it looked weird, could you add one just as an example and I'll copy that? CT55555 (talk) 19:02, 30 January 2022 (UTC)[reply]
    There are a couple different ways of doing it. A couple sources up, "Radioactive and toxic waste from the Bancroft..." only uses page 12 so you can add |page=12 within the citation template. Using {{rp|12}} right after the ref tag(s) is another simple way, and works better if different citations are using different pages of the same source. A third way, which is more complicated but is more organized if an article uses a multiple pages from multiple text books, is to use {{sfn}} with separate footnote and reference sections.
    • By 1958, Canada had become one of the world's leading producers of uranium; the $274 million of uranium exports that year represented Canada's most significant mineral export. page 1 (introduction)Checked
    • [Bancroft] is one of only a few places in the world and the only area in Canada where uranium is extracted from pegmatitic rock. Source page 11: "The first deposit of this kind [pegmatitic] to be developed successfully was the Bicroft, near Bancroft, Ontario. Production began there in 1956 followed shortly afterwards by production at the Faraday mine, and later by two others, all in the same area." and page 175 "The Bancroft region is the only part of Canada where uranium is produced from deposits of the general pegmatitic class, and is one of the few such places in the world." However, the source is from 1962 and may be outdated. Suggest changing: only area → first area, or adding a citation from a more recent source.
      Well that was fun, I looked it up and found a 2009 source saying that Bancroft is actually the only place in the world where uranium was mined from pegamite rock and it lists the other places where uranium was mined from intrusive rocks (which pegamite is a sub set of) so I now have a more up to date citation and a more powerful statement.

    • In 1943 [...] the government sent geologists to Bancroft, who concluded at the time that all known uranium despots were unviable due to accessibility, size and uranium concentration. also page 175Checked
    • 1948 saw an increase in private staking of claims for uranium, but due to the difficulties in extracting uranium from lower grade ore, none developed into mines. In 1953 "intelligence prospecting and excellent preliminary explorations" by G. W. Burns and R. J. Steele discovered the Central Lake deposits (which later were developed into Bicroft Mine) and Arthur Shore (whose prospect became the Faraday Mine) led the way successful prospecting. pages 176–177. The quote should be "intelligent prospecting and excellent preliminary exploration" which is applied to all three figures.
      I've made the correction to the quote, did I need to do anything else - i.e. does it seems like I've not applied to quote to all three of them? CT55555 (talk) 03:05, 24 January 2022 (UTC) Checked will address the phrasing under Prose comments[reply]
    • Much of the mine history from pages 177 and 179–186.
      • After borrowing a Geiger counter from a Mr Robbert Steele in Peterborough, he confirmed radioactivity and immediately started staking land claims. His slow careful staking disadvantaged him → He brought the samples to Robbert Steele in Peterborough who used a Geiger counter to confirm their radioactivity. The two then formed a partnership and immediately began staking land claims. Their slow and careful staking disadvantaged them ... their work ... they started, etc.

    • started diamond drilling, mostly to 100 feet, sometimes to 50 feet. I first thought this was depth (which is rather shallow) but it's actually the intervals at which holes were drilled. So: at intervals of 100 feet, sometimes 50 feet.

    • All other citations of this source for Bicroft Mine section are good.Checked
    • 1957 production or uranium was 405,271 pounds of ore that was 0.0859% U3O8. This differs from page 183 of source "Mill feed for 1957 averaged 0.0859 per cent U3O8, and 405,271 pounds of U3O8 were produced from the Faraday mine in that year." The pound figure is for the refined U3O8; the ore total would have been on the order of 230,000 tons. Suggest: Production in 1957 was 405,271 pounds of U3O8 from ore with a grade of 0.0859%. or Ore mined in 1957 had an average grade of 0.0859%, from which 405,271 pounds of U3O8 was produced.

Suggest: They found exposed rock to be radioactive across a 60-by-300-foot (18 by 91 m) area. or They found a radioactive area of exposed rock which was 60 by 300 feet (18 by 91 m).

    • Ownership subsequently shifted to Goldhawk Porcupine Mines Limited. I think this is backwards. Ownership changed from Goldhawk Porcupine Mines Limited to Greyhawk Uranium Mines Limited. Also, the source seems to say that ownership was transferred in 1955... so maybe place this somewhere between the discovery and the shaft.
Yeah, that makes sense, it already was porcupine. I've changed it and made things chronological. CT55555 (talk) 03:05, 24 January 2022 (UTC)Checked[reply]

    • By 1962 and 1963 the government was buying more than $1,500 million of uranium from Canadian producers for export, but soon thereafter the global supply of uranium increased, prices fell and the government cancelled all contracts to buy. I'm not finding this in the source.
      Sorry, I did the wrong recite, it's in the Geological Survey doc that Yukon Uni hosts, I've corrected the citation. CT55555 (talk) 03:05, 24 January 2022 (UTC)[reply]
      Found on page 11 of that source.Checked However, the phrasing led me to think this was not an annual purchase figure but rather the total purchases to date (or projected, with the years being the years the purchase contracts ended). Also, was all of this for export? (The National Research Universal reactor and Nuclear Power Demonstration would have used a small amount of this.) Suggest: was buying → had bought and remove "1962 and" and "for export". Not done
I missed this earlier. Sorry. I've changed it as you suggested and you make a good point about Canadian use. I'd guess a tiny fraction was used locally, but I can't write this based on guesses, so I just dropped the "for export" part as the surrounding article strongly suggests it's for export and the reader can draw their own conclusions, I think.

    • After mining, the uranium ore was treated in acid leaching plants located at the mines. The leaching process produced yellowcake high-grade uranium compounds which were either processed further at the Port Hope refinery or sold to the US government for processing in that country. Processing uranium ore in Bancroft cost $3.00 per ton. I'm not finding this in the source, though I believe at least part of it might have been in the previous source.
      You are correct, I've added the correct citation. CT55555 (talk) 03:05, 24 January 2022 (UTC)[reply]
      For the last sentence, the $3.00 figure is estimated in the source. I would suggest either adding "an estimated" or removing the ".00" so that it is a round figure of $3 rather than the implied precision of $3.00  Not done
      The rest of that passage has now been cited to Proulx (next below), where I found it on page 61.Checked
  • The Uranium MIning Industry of the Bancroft Area Proulx, 1997. This is a master's thesis. Per WP:SCHOLARSHIP, "Masters dissertations and theses are considered reliable only if they can be shown to have had significant scholarly influence." So I'd prefer a better source for the following:
    Google Scholar gives four examples where peer reviewed scientific papers cite it, which I think is uncommon for a masters thesis, I've seen PhDs with less influence than that. Does that extra info change your mind? CT55555 (talk) 03:05, 24 January 2022 (UTC)[reply]
    Update, as I worked to get all the uranium data, I updated other pages, removing citations to this masters thesis. That prompted someone to object, pointing out that the author of the masters thesis is a credible source and works for the Ministry of Natural Resources in Canada. This is easy to verify.

    FLAGGING THIS AS AN UNRESOLVED ISSUE
    Thanks for your further research on this; apologies if it got you into a conflict on the other article. Just doing my due diligence on this one, per that content guideline. From what you've discovered it sounds more reliable than your average master's thesis, though it doesn't seem like she was employed or sponsored by the Ministry at the time she wrote it. Could you link your Google Scholar search results?
Here is my link https://scholar.google.com/scholar?hl=en&as_sdt=0,5&q=The+Uranium+Mining+Industry+of+the+Bancroft+Area
And the four things that cite it are: https://www.sciencedirect.com/science/article/pii/S004896971732154X https://www.sciencedirect.com/science/article/pii/S0265931X16301588 https://eprints.soton.ac.uk/403374/ https://search.proquest.com/openview/c65c823b5613d79b21f402b3e36db7ff/1?pq-origsite=gscholar&cbl=18750

    • Bancroft today is known for gems and mineralogy, and has three abandoned mines and one that is being rehabilitated. This is also covered by the Reynolds source, but Reynolds is 1979 and I'd prefer a more recent source for 'today'.
      It would be easy to get more on this, but my easy solution is to cite the 2019 gem paper plus the Canadian Nuclear Safety Commission (all mines but Greyhawk) and then the government citation on Greyhawk. CT55555 (talk) 03:05, 24 January 2022 (UTC)Checked[reply]
    • The success of the mine was due to a combination of factors, and not simply because of Arthur Shore's discovery of uranium. The factors that resulted in economically viable mines were Bancroft's geographical proximity to industrial centers (Port Hope), a good road and rail network I'm pretty sure that there are some other sources which would cover this, if you could add another citation.
      I may struggle with this. I found her analysis excellent, and in the ton (or tonne?) of reading I did, I did not see that anywhere else. If you don't accept my earlier comments about the influence of her paper, this is the first unfixable problem I've found so far. And yet it's an important details. I'll research this thoroughly if you don't think her masters thesis is punching above its weight. CT55555 (talk) 03:05, 24 January 2022 (UTC)[reply]

    • The combination of a global decline in demand for uranium [...] combined with the more efficient extraction occurring in Ontario near Elliot Lake
      Reynolds book is clear about the dip in global demand, so I've added that. If you don't accept the masters thesis, I can change to quote the Yukon hosted geological survey docuemnt that describes Elliot Lake as the leading uranium field and describes how rapid and low cost methods of extraction were adopted. But it doesn't compare or mention Bancroft. So maybe I could find words that say the globel dip in demand, coinciding with new low cost extraction methods being found in elliot lake....or I could just drop the elliot lake thing, it's not important, again, depends if you'll reconsider the thesis.

    Sorry, I've come back to this a second time, but remain confused, I'm a bit of a wikipedia newbie, so I'm not disagreeing with anything, just literally confused by what you're saying/asking. CT55555 (talk) 00:57, 19 February 2022 (UTC)[reply]
    (see following)
    • Verified for dates. You might use this source to flesh out some of the other entries, like the Fission/Richardson mine
      I'm confused here still. I should use the http://www.csun.edu/~vcgeo005/gentry/canada.htm source to add content where?
      FLAGGING AS UNRESOLVED
      Let's see if I can explain about the website vs journals. https://www.csun.edu/~vcgeo005/gentry/tiny.htm is a page someone has hosted on a back page of the website of California State University Northridge. It is a reprinting (of uncertain editorial oversight) and may have introduced copying errors or have actually edited or revised the material (perhaps to suit use as class material). (It's also possible that it was reproduced on the website without permission, and Wikipedia has a rule against linking to copyright violations, though we could AGF.) A version published in a reputable journal will have had objective editorial oversight and been checked for errors. Although they appear to have the same origin, a version from a journal would be considered more reliable. So what I'm suggesting is to rework the {{cite web}} as {{cite journal}} and note a journal where it was published. I spent a little more time comparing them, and the website has substantially different phrasing from https://ncse.ngo/gentrys-tiny-mystery-unsupported-geology (journal of the National Center for Science Education) though the content is remarkably similar. Wakefield may have rewritten the article for this publication's readership a few months after it appeared in Journal of Geological Education. Here is the relevant passage from either source:
      • CSU: The Faraday Mine pegmatites have been dated at between 992 Ma and 1088 Ma by several methods (Easton, 1986a,c). The Faraday Batholith, just to the north, was dated at 1190 Ma. Though no dating of the Faraday gabbro has been done, other gabbros of similar composition, (like the Tudor Gabbro just to the south) in the area have been dated at 1180 Ma (Easton, 1986a). The Silver Crater deposit has been dated at 1000 Ma (R. Gait. Mineralogist, Royal Ontario Museum, personal communication, February 1987), and the Fission mine is closely related to the Silver Crater in age.
      • NCSE (page 21): The Faraday Mine pegmatites have been dated at between 992 million years to 1,088 million years by several methods (Easton, 1986a; 1986b). Though no dating of the Faraday gabbro has been done, other gabbros in the area of similar composition, such as the Tudor Gabbro, have been dated at 1,240 million years (Easton, 1986a). The Silver Crater deposit has been dated at 1,000 million years (Galt, 1987) and the Fission Mine is closely related in age.
      Either supports the material in the article. I feel that NCSE would be sufficient, though the Journal of Geological Education version may be a bit more formal, scientifically.
      So, long story short, I would recommend changing the article source to the NCSE version, after you have read that passage and are satisfied that it supports the material in the article and is reliable. I'd suggest placing a wikicomment with the citation template noting the earlier paper in May 1988 Journal of Geological Education. (Volume 36 no 3 pages 161–175, DOI 10.5408/0022-1368-36.3.161 https://www.researchgate.net/publication/315480397_The_Geology_of_Gentry's_Tiny_Mystery ) If you are confident that the website is faithfully reproducing this article, then you can use this as your source. I'm not confident enough to recommend this.
Actually upon reading the original, saying it's about 1,000 years old is too much of a simplification, as other parts are understood (but not confirmed) to be around 1,200. I've changed the source and the words. CT55555 (talk) 00:59, 5 April 2022 (UTC)[reply]

    The masters thesis actually says Bicrot mine employed up to 619 people at peak and cites the Ontario Department of Mines, so I've put a manual citation in, although that's assuming the masters thesis is in good faith, it's published on the federal government of Canada's website, so I'm assuming yes?

The Co-Authorship at the beginning notes that parts were intended for journal publication.

    WP:Reliable secondary sources. GA criteria 2b requires reliable sources (and depending on the nature of the material secondary sources are generally preferred). Sort of the same thing as website vs journal above, only this is thesis vs journal. The journal publication is more reliable, a higher quality source. If you go to FAC, they'll want all sources to be of high quality. Here, I would consider both to be reliable but maybe leave a wikicomment at the citation template if a future editor can find the journal.

      Fair. Probably I didn't cite this well enough, I guess I was thinking if the source said they were fixing it, it implies it was broken. I'm adding in this citation: https://www.nuclearsafety.gc.ca/eng/the-commission/meetings/cmd/pdf/CMD21/CMD21-M34.pdf , hopefully that clarifies...it may not...it's not clear to the lay reader. But it says on page 133 that there are upgrades to the tailings (TMA) cover and improvements to the stability of the spillway. I guess it could be argued that just because they are fixing it, doesn't necessarily mean it's broken, but for that to be a credible alternative explanation, we'd need to imagine that the regulator required a company to improve something that was already fine and I guess that's close to impossible. I recognise maybe I'll need to change the words to "the regulator reported improvements"? What do you think? CT55555 (talk) 14:23, 24 January 2022 (UTC)[reply]
      It says "rehabilitation/maintenance work on the [tailing management areas]". Rehabilitation could mean the ongoing planting of shrubs and trees, while maintenance could mean preventative maintenance (which I hope would be common with nuclear safety). So it doesn't really say to me that something was wrong, let alone that an official inspection found a problem.
If I cited page 76 of Proleux, would that back this up? Here's a quote (optical character recognition is poor, so many errors

"In 1987. MadawaSka concluded in its Annual Report: "No. 2 Tailings Area has been stable for thirty years and is considered to have retuned to the

typical background levels of radiation for the area (MML 1988 2-40}. At that time. the AECB undertook a gamma survey along two transects and the readings of 800 to 900 R/hr demonstrated minimal cover on some parts of the tailings area in 1988, its refusal to grant approval to abandon the property- the AECB referred to Locations on the tailings with high gamma readings and sinkholes indicating ongoing stabilization (MML 1989 Appendix 2). In L989. MML resisted assuming responsibility for remedial work on tailings Area No. 1, citing thirty years of growth of indigenous vegetation and placement of cover only on parts of the tailings am as requested by the AECB. In 1990, Madawaska agreed to undertake

remedial work on the No 2 Tailings area. This was contracted to to Break Consultants who removed existing vegetation and placed cover in 1991. In 1993. Red pine seedn,gs were planted on the site and no further work was planned"

      I may have been too picky about that; things which are generally verifiable don't need to be cited unless they're likely to be challenged. (I prefer that they are cited, but it's not in the criteria.) I wonder if this nomenclature simply signifies the activity on the property, whether it's a claim, a mine, or a decommissioned mine/rehabilitated land?
I get the impression that in the early days of all mines, people were quite casual about calling them "XXXX property, XXXX prospect" and that things got written down later. I assume not much uranium was produced, otherwise there would be more records, and so I assume there wasn't much to decommission, I've been able to find so much more about the others. I consider the name in the article not controversial - but have made an edit to just call it "Kemp" which covers all bases, I think. CT55555 (talk) 15:24, 20 April 2022 (UTC)[reply]

    James Ham is the commmissioner of the RCHSWM. I thought that the report is the work of the commission, written collectively by the seven people on its first page (and possibly others). (I mention page numbers above; may do this myself.)
    I see your point now. I have always considered (and I created the Royal Commission on the Health and Safety of Workers in Mines article) him to be the author, but I never really critically reflected on why. I think it's because page 10 of the archive of it has a cover letter in which he describes it as "my report" and I've read a lot of health and safety documentation that always referred to him as the author, and the architect of modern health and safety legislation in Canada. OF course, that could all be wrong. So I'm not sure. I see no problem with changing the author to the commission, I doubt we could find anything that would explain the division of duties between the team. What is relevant (or at least interesting) is that Canadian commissions tend to be known by their nickname, I think always the name of the author, and this one is known as "The Ham Commission" [[1]] CT55555 (talk) 15:35, 20 April 2022 (UTC)[reply]

    • In the 1970s, the scientific community was making connections between uranium mining and silicosis in miners. Uranium mining produces silica-laden dust and the health risk to miners is correlated to the amount of free silica in the uranium ore. Whereas the uranium mines in Elliot Lake produced ore with a free silica rate of 60 to 70%, the dust from the miners around Bancroft had 5 to 15% free silica, thus presenting some risk to miners, but much less than that of the Elliot Lake's uranium mines. In 1974, the Ontario Workmen's Compensation Board studied 15,094 people who worked in uranium mines in Bancroft and around Elliot Lake for at least one month, between 1955 and 1974. Of those 15,094 people, 94 silicosis cases were found in 1974, of which one was attributable to working a Bancroft mine, i.e. the other 93 were attributable to working in an Elliot Lake mine. I found some of this from page 18 of source. I did not spot (a) the correlation of the amount of free silica to miners' health risk, or (b) the study of 15,094 people. Page 43 talks a bit about dust levels but I don't see it making that connection. Page 62 footnote 23 mentions "some fifteen thousand" persons with a month exposure in Ontario uranium mines.

    • The aforementioned 1974 study of 15,094 Ontario uranium miners found 81 former miners who died of lung cancer. Factoring in predicted lung cancer rate for men in Ontario, led to the conclusion that by 1974 there were 36 more deaths than expected attributable to both Bancroft and Elliot Lake mines, with the additional risk being twice as high for Bancroft miners compared to Elliot Lake miners Page 84 states "There is statistical evidence based on samples that for persons who ever worked in the Bancroft area mines the risk of lung cancer has been 2.2 times that for persons who never worked at Bancroft." I'm not sure if that means 2.2 times greater than those who worked at Elliot Lake or 2.2 times greater than the general population. Page 324 states: "it appears that men with any period of employment at Bancroft have experienced a lung cancer risk about twice as great as that for men who have worked only at Elliot Lake." I feel that "appears" isn't strong enough for a conclusion of the study. I'm not sure if the numbers of miners were pulled from the table on that page or elsewhere.

    Okay, I think I found your original from November 2021: The volcanic eruptions spouted through sediments recrystallizing them into layers of banded gneisses including limestone, graphite, gabbro and diorite producing iron and other dark minerals. I believe that clears up the meaning for me. If I have this right, producing opens a new clause which applies to all that came before it. Limestone is sedimentary and not a gneiss, so the list are not examples but other contents of the 'layers' along with the gneisses. Here are a couple ways I'd rephrase it:
    • recrystallizing them into layers of banded gneisses – incorporating limestone, graphite, gabbro and diorite – rich in iron and other dark minerals
    • recrystallizing them into layers of banded gneisses rich in iron and other dark minerals, limestone, graphite, gabbro and diorite.

Add that to the end of the preceding paragraph. (This would also avoid the problem of having to define the mines at this early stage of the article.)

  • Prior to the 1922 discovery of uranium, mica, feldspar, and other minerals were mined on a small scale in the Bancroft area. It might at first appear to the reader that uranium is the first element of an inline list 'uranium, mica, feldspar, and other minerals'. There's also some ambiguity with the discovery of uranium as an atomic element (which happened much earlier). Suggest removing the first clause altogether as a rephrase would get a bit wordy. Actually, let me take a run at the whole combined section:
    • Suggest: "Finds of gold in nearby Madoc, Ontario, (then known as Eldorado) from 1886–87, inspired many to seek gold around Bancroft. Surface gold was found in October 1897 by R. Bradshaw, 20 miles (32 km) southwest of Bancroft (towards Bobcaygeon). This triggered a rush of prospectors to the area. Iron and magnetic ores were mined from 1882, gold, copper and mica from the late 1890s, and marble from 1911. More than 1,600 identifiable minerals and non-metallic collectibles can be found in the area,[1] including 175 species of gemstones.[2]" I think this hits the important points. If you want to include the gemstone list or the factoid about the ROM floor, those could probably be footnotes.

    I see what you mean. Changing the section titles may be the way to go. I've had articles which changed their title because they gathered material that changed their scope. What would you think of a single paragraph like:
    After $7 million of investment to modernize the mine,[1] it reopened as the Madawaska Mine in 1975 and the shaft into the uranium-bearing pegmatite was extended to a depth of 473 metres (1,552 ft).[26] During this period, the mine was producing 1,500 tons of ore per day.[1] The mine closed in 1982.[26] In 2015, inspections found improper surface protection of the tailings and the site has been undergoing rehabilitation.[7] Question?
I find the words agreeable, I am just still resisting merging the two paragraphs because it seems to me that every mine section is subdivided into obvious chapters, and the decommissioning chapter is chronologically, ownership-ly and operationally distinct between the second period of extraction and the rehabilitation period.

Other construction quickly followed, including two single-men's bunkhouses, a canteen, an eleven-room school, an ice-curling rink, and a recreation center. In 1957, a swimming pool was started.[27]

  • Same sentence: from intrusive rocks, the others being I feel like you need stronger separation here than a comma: either a semicolon or a dash.
  • Section gems and other resources: I believe that I proposed the second paragraph to replace the first; you don't need both.
  • I think you added some to this sentence and it runs a bit long. Uranium was first discovered in the area of Cardiff, Ontario, in 1922 by prospector W. M. Richardson[1] at a location first called "the Richardson deposit" and later known as "the Fission property"[4]: 175  located two kilometers east of Wilberforce on the property know as lot four, concession 21 of Cardiff Township.[9] Suggest a sentence break after Richardson and then: His find was first called the Richardson deposit, and later the Fission property,[4]:175 and was located two kilometres east of Wilberforce on lot four, concession 21 of Cardiff Township.[9] (Note Canadian spelling of kilometre.)
  • Another run-on sentence: In 1953 "intelligent prospecting and excellent preliminary exploration" by G. W. Burns and R. J. Steele discovered the Central Lake deposits (which later were developed into Bicroft Mine) and Arthur H. Shore (whose prospect became the Faraday Mine) led the way successful prospecting.[4]:176–77  I feel it's cramming too many ideas together and should be split topically.

    • On second thought, the one-sentence paragraph which precedes this would fit nicely in the middle of this paragraph. So you'd have the sentence "In 1953" as constructed above, then "Between 1953 and 1956", then the third sentence could be "Burns and Steele discovered the Central Lake deposits, which were developed into Bicroft Mine, while Shore's prospect became the Faraday Mine."

Since four of the five mines have their own articles, ideally we'd want to migrate a lot of the information from those sections to the articles on the mines, and have the sections in this article tight summaries relevant to the overall subject.

For Greyhawk Mines, I feel that it could include from page 186 of Canadian Deposits of Uranium and Thorium that both the tonnage and grade of ore were below that indicated by surface drilling, which would help toward explaining why the mine shut down after only two years. Suggest something like: Operations uncovered no high-grade ore deposits, leaving the average grade below that of other Bancroft mines. The tonnage of ore was 30% less than feasibility estimates. – I think if you add that right before "Mining operations stopped" readers can draw a likely conclusion without a source explicitly stating it.

(If RSS can't be easily found, then the GA criteria won't require coverage.) Cursory search:

I've added Blue Rock and Nu-Age (i.e. Old Smokey). Cavendish is far away, not really "Bancroft Area" about 100km away and also it seems that exploration was done, but nothing mined. Tory Hill is geographically close, but there is nothing notable about them, despite having a name that is easier to search. CT55555 (talk) 02:27, 25 January 2022 (UTC)[reply]
Thanks, I appreciate this extra work! – Reidgreg (talk) 03:46, 4 March 2022 (UTC)[reply]

I was wondering if it might be worthwhile to note somewhere that the mines which reopened in the 1970s did so in the context of the 1970s energy crisis? Perhaps this could go just before However, by the 1980s, uranium demand was again down You wouldn't be able to state a causal relationship without a source, but you could state that there was an energy crisis and then state that some mines reopened, and readers can make the connection themselves. (I feel that there was an energy crisis in the 1970s is readily verifiable and its existence as an event doesn't need a citation.)Question?

I think this is great, it fills in a part of the story that I only just realized was missing. Of course this changes the "decline in demand" section into decline and increases. Should I change it to "Demand for uranium"? CT55555 (talk) 21:43, 20 April 2022 (UTC)[reply]
The section header could be something very generally like Decline, growth and decline. Alternatively, Response to global demand could work, but it seems a bit like a teaser, making you read to see what the demand and response were. It doesn't quite fit a boom-bust business cycle.Blue question mark?

Regarding the gem lists and marble buildings: I recently had a spirited discussion with a couple editors about inclusion of trivia. 'Trivia' is a bit of a trigger word on Wikipedia, like 'vandalism', and has been used for the wholesale removal of content. However, the importance of information is relative and subjective, and Wikipedia includes lots of notable trivia. When considering inclusion, a good gauge is the information's relevance to the article topic. My first inclination was that the marble floors of the ROM and the gemstone list were at least once-removed from 'uranium mining in Bancroft', and weren't necessary to a summary of the article subject. However, I don't think it's that bad of a thing to have at the end of a section, and goes a way to including some of the galleries. I won't hold up the review on it.

Thanks. I agree, they are one step removed. If this was "extraction in the bancroft area" they would be in scope. I could have started the article that way, but I didn't, as such an overwhelming amount of what was extracted was uranium. If wikipedia is a place to learn, I see this serving a good function, directing people about other topics, a bit like a "see also" section. So while I'd accept it if you insisted I remove it, I like that we can keep it in, I think it increases human learning without detracting from the article.

Neutrality

[edit]

Some minor tone issues covered elsewhere in review

Stability

[edit]

Although there were some recent-ish interest in renewed mineral explorations, no new uranium mining activity has been initiated and it is a mature topic which with no content disputes detected in the article.

Media

[edit]

All 23 images tagged with free or creative commons licences. The interactive map is generated through Wikimedia maps and OpenStreetMap, so I assume it is not a problem.

GA criteria 6b requires media [to be] relevant to the topic, and have suitable captions.

  • The two images in the lead are a century apart, with the period when uranium mining was conducted roughly in the middle of that. It'd be nice if there was an available image from the period when uranium mining was underway, but we work with what we have. I would say to keep the 2009 image as the lead image, and move the 1910 image down to where the article talks about iron mining and marble quarrying.

You experimented with {{Multiple image}} in Faraday/Mining operations. Unfortunately, the template is fixed-width and when you have four images side-by-side it can break the sides of the margins on smaller screens (try narrowing your browser window to see). I'd suggest reducing the image size, putting them 2×2 instead of four in a row, or go back to a gallery (which most browsers will automatically adjust for window width).

I've done it. CT55555 (talk) 22:03, 20 April 2022 (UTC) Checked[reply]

Doing another check for new images.

  • Four new images, all tagged with free license and illustrative of accompanying text.
  • I cropped the Arthur Shore image so it just shows the picture, without the newspaper text. I added a bit to the file description. If there was any other information from the newspaper article, please add that as well, it's good to have a thorough description.
    • It's okay now, but for a while it was displaying the original image scaled to the size of the cropped image – really weird! I tried manually purging the article page but it took about a day for it to sort itself out (perhaps the problem was actually my browser cache?).
Sadly the image I had of Mr Shore was already cropped, so I don't have more info. Thanks for your work on that. CT55555 (talk) 22:04, 20 April 2022 (UTC) Checked[reply]

Even more new images:

  • The two period pictures of the Madawaska Mine entrance are licensed and relevant. I moved them down a bit to avoid image overcrowding.

Yet another new image:

  • The Caterpillar bulldozer is a nice bit of mining operations.Checked
  • Henry Maloney picture – the fair use is good for the Henry Joseph Maloney article, but it may be a stretch to include it here as well. This is not my area of expertise, however, and the licensing information is on the page as required.Checked

Lead

[edit]

Since we're pretty sure about the article content at this point, I think we can start tackling the lead. I'd like the lead to be in very good shape, as it's the first thing people read – and tends to be the first thing people edit as well.

Assuming everything that appears in the lead is also in the body of the article (which it generally should be), inline citations are only required for quotations and material likely to be challenged.

  • The discovery of uranium near Bancroft resulted in what was described by engineer A. S. Bayne in a 1977 report as the "greatest uranium prospecting rush in the world" Good for quote, but the report says that the prospecting rush was triggered in "1953, when Centre Lake Uranium Mines Ltd. started underground development".

I'm going to go ahead and try a rewrite of the lead for MOS:LEAD compliance (GA criteria 1b). I'll be aiming for easy to read prose which clearly and succinctly serves as a summary of and an introduction to the article, organized in two or three paragraphs. Again, the GA Somerset Coalfield may serve as an example.

Uranium mining in Bancroft represents one of two major uranium-producing areas in Ontario[1] and one of four in Canada,[?] all located along the edge of the Canadian Shield. In the context of mining, the "Bancroft area" includes Haliburton, Hastings, and Renfrew counties, and all areas between Minden and Lake Clear.[1] Activity in the mid-1950s was described by engineer A. S. Bayne in a 1977 report as the "greatest uranium prospecting rush in the world".[2] Mining activities were conducted during two periods, 1956–1964 and 1975–1982, when uranium prices made underground hard-rock mining of the ores economically viable.
As a result of activities at its four major uranium mines, Bancroft experienced rapid population and economic growth throughout the 1950s.[1] By 1958 Canada had become one of the world's leading producers of uranium; the $274 million of uranium exports that year represented Canada's most significant mineral export.[6] By 1963 the federal government had purchased more than $1,500 million of uranium from Canadian producers for export, but soon thereafter the global supply of uranium increased, prices fell and the government cancelled all contracts to buy.[6] Mining resumed when uranium prices rose during the 1970s energy crisis, but this was not long lasting. Bancroft continues to be known for gems and mineralogy,[2] and has three abandoned mines and one that is undergoing land rehabilitation.[7] A negative impact has been a twofold increase in lung cancer development and mortality among former mine workers.[9]

What do you think?Question?

I like it. I added it in. I made a few tiny tweaks (commas, new paragraphs) and changed four to seven (after counting up the areas, it's two other provinces, but they are sub divided). And I rewrote the last sentence. CT55555 (talk) 22:26, 20 April 2022 (UTC) Checked[reply]
Looks good, though I seem to have contradicted my own advice by putting "for export" back in. (Perhaps you could remove that?) More importantly: an article of this size should have a lead of two or three paragraphs (MOS:LEADLENGTH). So you're going to have to get those five paragraphs down to three, however you wish to combine them. – Reidgreg (talk) 01:02, 6 May 2022 (UTC)Blue question mark?[reply]
I edited out "for export" and combined the sentences to make a total of 3 paragraphs. CT55555 (talk) 00:36, 7 June 2022 (UTC)Checked[reply]

Other areas to improve

[edit]

Please ignore this until the points above are addressed. Although not part of the GA criteria, here are some other areas you might eventually want to improve:

  • Articles should express measurements in both metric and Imperial units. This article has a mix of each. Choose one as the primary system for the article (typically metric for Canada) and use {{convert}} templates to supply the other with formatting. If you want, I can take care of this after the nomination is closed.
    I've never done this, I'd love it if you could, also I assume we'd do this last, once everything else is water-tight CT55555 (talk) 02:27, 25 January 2022 (UTC)[reply]
  • The map in the article might also include Cheddar, Ontario (now a ghost town within the township of Highlands East, Ontario). One of the maps in the sources outlines the Cheddar granite, Cardiff plutonic complex and Faraday granite; it'd be a bit of work, but creating a map that outlines these features along with the locations would be quite illustrative for the article.
    I've added Cheddar, but have no idea how to add drawings etc. CT55555 (talk) 02:36, 25 January 2022 (UTC)[reply]
  • Standardize the references a little more for FAC (particularly the date formats).
    I'm happy to do this, but can you please be more specific? Is there anything other than dates? And which date format is best? CT55555 (talk) 02:36, 25 January 2022 (UTC)[reply]

Reference tidying is about organizing it a bit so it's easier to work with. Like making a uniform system of names for the references (rather than the auto-generated ":1" types). Authorsurname-year or institution-year are often a good way to go, or maybe use the title or purpose, just so long as they aren't easily confused.

Another big part is using the appropriate citation template. If you're researching via the Internet, most of your sources will have websites but often there will be a better template to use than {{cite web}}. I've mentioned a couple where cite journal is better. For GEOSCAN Search Results: Fastlink, it'd be better to use {{cite report}} with the url https://gac.ca/wp-content/uploads/2019/10/GAC-MAC-2013-program-with-abstracts.pdf and page=157 (where the information is at the bottom). When you do use cite web, note the difference between |website= and |publisher=. If it's an online news source or magazine, use website; if it's an institution like a government website, use publisher. (Hint: website applies italics while publisher does not). Read through the parameter use in the documentation of the citation template and make sure you're using them appropriately.

Dates: When there are multiple valid styles, MOS generally says to go with the 'established style' of the article – meaning that it's your choice as the article's creator and primary author. Sometimes the established style will be changed with major rewrites, such as here at a GA review, or otherwise after considered discussion. Because the article is about Canada, we will generally use Canadian English and metric. Other styles like date formats and whether to use serial commas are up to you. I personally like dmy dates with the month written out. These are non-ambiguous, and they avoid the MOS:DATECOMMA issue that inevitably comes up with mdy dates.

At the FA level, images should have |alt= text for accessibility. While the caption explains context and relates the image to the text, the alt text describes the image itself. (more at Wikipedia:Manual of Style/Accessibility/Alternative text for images).

For the article map(s), consider placing a request at Wikipedia:Graphics Lab/Map workshop. There are all kinds of specialist editors on Wikipedia, and these folks know everything about maps. They can tidy up that map as a scalable SVG, colourize it, add or remove features, and advise on any copyright issues (probably not a problem; you can copyright a map but you can't copyright the information on the map, so when they make a new one it will have a free license regardless of the original). Just make sure you know exactly what you want and clearly state your request (with sources as applicable).

General discussion

[edit]

You can post any general questions or discussion here. If you have any questions about the specific points above or want to discuss them (and feel free to disagree with me), please post such following the appropriate bullet point above. Try to preserve the list formatting and talk page conventions to keep it tidy and so it's easy to mark our progress. When you've finished making changes to the article, please let me know here and I'll check through your changes. Reviewers usually give 7 days for changes to be made to meet the criteria, but I'll probably go as long as a month since this is your first GAN and the review is fairly long. – Reidgreg (talk) 17:09, 23 January 2022 (UTC)[reply]

I've done a first pass at everything. I've overwhelmingly agreed and there's just a couple of points I have pushed back on, none with strong disagreement, none major (other than the following). The only thing that I've disagreed with that seems important is the acceptability of the Master's thesis. My arguments for that are above . I should do a second pass before you review my actions, but before I do so, I have a question and that is about my over sectioning. I've cut it down a little in the first pass, but I assume you recommend more wholesale changes and assuming I'm correct about that do you recommend that I merge the "geology" and "operations" sub sections for each mine? Any other obvious merger points? I'm thinking the health section doesn't need sub sections. Maybe it would be fairest on your time if you answered these points and then I'll act on that and give everything a second pass. @Reidgreg: CT55555 (talk) 02:44, 25 January 2022 (UTC)[reply]
@CT55555: Just answering your question about the sections. I think the broad-strokes part of the layout are good. I like your addition of 'Other mines'. Everything's pretty much grouped together in a way that makes sense. I think I've come around and feel that the operations/geology parts work. I'd had an inclination to introduce the geology first and then get about how they dug into it to get the ore. However, those geology parts use a lot of specialized scientific language while the operations part is more accessible to the general readership, IMHO, so I feel that it fits the summary style concept of giving the overview first, followed by more detailed information. I'm not opposed to the subsections in health; it seems good to have some division there for the separate subtopics. The one I would definitely want to change is to get rid of the paragraph under 'Early mining efforts (1886 to 1922)' and use that header for the section now titled 'Gems and other resources'. And perhaps moving some things into footnotes (you may have addressed that in the review comments). I also keep thinking about different ways of placing the images (like maybe putting the uranium ore picture together with the yellowcake picture, or moving some of the gem gallery down to the gemboree text) but I'm not a real 'picture person' and don't have firm opinions about this. – Reidgreg (talk) 02:12, 26 January 2022 (UTC)[reply]
@Reidgreg:I've deleted that section and also combined "uranium discovery" with "uranium mining" since the former had only a few lines. I've deleted the dates for the top level sections, but kept them for mines where there were two mining periods. The gallery style of pictures isn't perfect, but when I put them on the right, they didn't fit. When I put them on alternative edges it looked unprofessional, this was my third approach and I think the best of an imperfect bunch. I'll review this again at the end in case the layout changes create more opportunities (they might). Obviously I need to give all the questions a second pass. I'm also keen to hear your thoughts about the Master's thesis, if you don't accept it, then I some major changes will be needed, I hope you will based on my arguments above. Those arguments are 1:a quick google confirms the author is a government official in a relevant department, and 2 the masters thesis is actually cited in published academic work, which I think is uncommon and demonstrates it has the abnormal influence that Wikipedia needed for us to consider it acceptable. CT55555 (talk) 03:06, 26 January 2022 (UTC)[reply]
@CT55555: The GA criteria for images are only (6a) that they are appropriately licensed and (6b) that they are illustrative and not merely decorative. Those gem and mineral pictures, for the most part it seems to me that they're only illustrative for the list of gems found in the area and I'm not sure that's even relevant to the article's topic. "The designer has achieved perfection not when there is nothing left to add, but when there is nothing left to take away."[1] But I don't feel strongly about it and don't want to make it a point of the review. The rest looks interesting. Let me know when you're finished making changes and I'll take another thorough look at the article. – Reidgreg (talk) 02:31, 27 January 2022 (UTC)[reply]
