Regulation S-K 1300 is a set of regulations implemented by the U.S. Securities and Exchange Commission (SEC) to modernize and improve the disclosure and reporting standards for mining properties. It replaced the previous Industry Guide 7, aiming to align U.S. reporting requirements more closely with global standards.

CRIRSCO’s International Reporting Template (IRT) played a significant role in the development of Regulation S-K 1300. The IRT provided a framework that helped harmonize the various national and regional reporting standards into a globally accepted guideline. This alignment was crucial in informing the SEC’s approach, ensuring that S-K 1300 would facilitate greater consistency and comparability in the reporting of mineral resources and reserves, aligning it more closely with international standards and enhancing the transparency of disclosures to better serve global investors.
