Desarrollos Mineros San Luis, S.A. de C.V. Becomes a Signatory to International Cyanide Management Code

The International Cyanide Management Institute (ICMI) announced today that it has accepted the application of Desarrollos Mineros San Luis, S.A. de C.V. (DMSL) to become a signatory to the International Cyanide Management Code for the Manufacture, Transport and Use of Cyanide in the Production of Gold (Cyanide Code). The Cyanide Code is a voluntary industry program for companies involved in the production of gold and silver using cyanide and companies manufacturing and transporting this cyanide. DMSL was acquired by Leagold Mining Corporation earlier this year, and operates the Los Filos Mine in Guerrero State, Mexico.

The Los Filos mine was operated by Goldcorp, prior to the sale, and the mine was last certified in compliance with the Cyanide Code in February 2014.  By becoming a signatory, DMSL commits to follow the Cyanide Code’s Principles and implement its Standards of Practice, and to have verification audits of the operation conducted by independent third-party auditors.

The Cyanide Code was developed under the aegis of the United Nations Environment Programme by a multi-stakeholder Steering Committee. The Cyanide Code is intended to complement an operation’s existing obligation to comply with the applicable laws and regulations of the political jurisdiction in which the operation is located.

ICMI has been established to administer the Cyanide Code, promote its adoption, evaluate its implementation, and manage the certification process. A detailed list of the operations covered by signatory companies’ applications, along with the full text of the Cyanide Code and its implementing and administrative documents, are available at
