Results available to date indicate that gold and silver mineralization from the Tonopah project are amenable to recovery by cyanide leaching. Test work has been completed on both fully oxidized and sulfide samples, with little difference noted in recoveries.
New Gold is an intermediate gold mining company.The company has a portfolio of four producing assets in top rated jurisdictions. The New Afton and Rainy River Mines in Canada, the Mesquite Mine in the United States, and the Cerro San Pedro Mine in Mexico (which transitioned to residual leaching in 2016), provide the company with its
Outotec offers complete cyanide leaching plants irrespective of the material quality. Free milling gold materials are cyanide leachable and so are the refractory gold materials after suitable pre treatment.
