MEXICO – The International Cyanide Management Institute (ICMI) of Washington, DC, has certified that Yamana Gold‘s Mercedes mine in Sonora state is in full compliance with the Cyanide Management Code. ICMI accepted the findings of a third party auditor that the Mercedes mine meets all the criteria outlined in the code.
The Mercedes underground mine began production in late 2011 in tandem with a 1,500-t/d mill, and commercial production was reached in February 2012. In 2013 it produced 141,618 gold equivalent ounces. Proven and probable reserves at the end of 2013 stood at 5.6 million tonnes grading 4.69 g/t Au and containing 845,000 oz of gold.
The Cyanide Code is a voluntary industry program for companies involved in the production of gold using cyanide and companies producing and transporting this cyanide. It is intended to complement an operation’s existing obligations to comply with the applicable laws and regulations of the political jurisdictions in which the operation is located.
