The site isn't about mine safety disclosures—it's just a name.

A quirky requirement that came out of Dodd-Frank is that ALL publicly traded companies are required to make a disclosure about mine safety, regardless of whether or not they even have mines. So if you look at Visa's 10-K, or Google's, or Chipotle's, they all have a line item for mine safety disclosures.

I'm guessing it's a tongue-in-cheek nod at the requirement for Mine Safety Disclosures you'll often see as a blank section in company filings. It looks more like a finance/investment website.

Edit: For example, page 45 of Apple's most recent 10Q https://www.sec.gov/ix?doc=/Archives/edgar/data/320193/00003...
