In the 4th quarter of 2018, the SEC finalized amendments to the disclosure requirements for mining companies under the Securities Act of 1933 (“Securities Act”) and the Securities Exchange Act of 1934 (“Exchange Act”). See HERE. In addition to providing better information to investors about a company’s mining properties, the amendments were intended to more closely align the SEC rules with industry and global regulatory practices and standards as set out in by the Committee for Reserves International Reporting Standards (CRIRSCO). The amendments rescinded Industry Guide 7 and consolidated the disclosure requirements for registrants with material mining operations in a new subpart of Regulation S-K.
The final amendments require companies with mining operations to disclose information concerning their mineral resources and mineral reserves. Disclosures on mineral resource estimates were previously only allowed in limited circumstances. The rule amendments provided for a two-year transition period with compliance beginning in the first fiscal year on or after January 1, 2021.
