... that Gevra mine of Korba Coalfield is the largest open cast mine in India with a record daily production of 100,000 tonnes? -- See ALT1 hook below

I have not fully reviewed this article and hook yet. I conducted a limited review and identified some concerns:

Hook: In the article, the first part of the hook fact ("largest in India") is sourced to this page on the Korba District website, which states "Gavra Project is largest Opencast Mine in India". As written, the hook implies that this is the largest mine in India, not the largest "open cast mine." While it is likely that the country's largest open-cast (open-pit in U.S. English) mine is also the largest in the country, the article and the hook both need to be explicit about what this mine is the largest of. Additionally, I have some doubts about the reliability of that source, since the overall tone of the website is promotional -- not a style normally associated with thorough fact-checking. The second part of the hook (the one-day record output of 100,000 tonnes) is supported by a reliable source ([1]), but I note that the source is careful to say that this was a claim by the company SECL -- this indicates that the claim is not verified as fact.
Article: The second paragraph identifies the Geological Survey of India as the source for some of the information given, but the only source cited for that part of the paragraph is the company SECL. The Geological Survey of India is not listed as a reference for the article. If the information in the article is attributed to a source, there should be a proper reference citation to that source. --Orlady (talk) 18:47, 3 September 2011 (UTC)

I have modified the hook and made it more specific.
I have added more references for both the estimated reserves and for the 'largest' claim.
In India, all mineral reserves are estimated by Geological Survey of India, but I was unable to locate direct GSI references. I have given indirect references mentioning GSI. I have deleted GSI from the article.
Reuters says that Gevra is the largest Open Cast Mine in Asia, but I have struck to largest in India claim (adding largest in Asia as a secondary claim in the article only.)
I am unable to locate a second independent reference for the record output part. If required that can be deleted from the hook. I have added two more references but they seem to be inter-related.

Sorry for all the trouble and thanks for the interest taken in this.

I have added data for reserves from Geological Survey of India site.- Chandan Guha (talk) 10:56, 6 September 2011 (UTC)

Everything checks out now. (Sorry that it took me so long to get back to this.) Article dates and length are fine. Article has been nicely improved since my first comment above. Article is well-supported by citations, I have read several of the article's sources and I did not find evidence of plagiarism. The hook facts are now thoroughly supported. I revised the article to include the "largest in Asia" claim, as well as second-largest in the world, but with language to indicate that these are how it "has been described." It is clear that this mine is huge -- it's unfortunate that the photos in the sources are not freely reproducible. I have re-worded the hook (which is, by the way, very interesting) so that it is fully supported by both the article and the sources, and to include the "largest in Asia" claim in place of "largest in India":
