p. 3 "Effective 2017, the Mint's Responsible Metals Program Guidance specifies that (i) as part of a site visit to a high-risk gold mine site the Mint will conduct sample due diligence over transactions, or the supplier's transaction records to ensure that the origin of gold is traceable within the supply chain, and (ii) follow-up site visit(s) for high-risk supply chains will be carried out within a reasonable timeframe, and the frequency of those will depend on a number and severity of issues identified in respect of the supplier."
