RE:RE:RE:RE:mining.com article on copper

BINGO!!!!!!!!!!!!!!!! WHAT WEVE ALL BEEN WAITING FOR!!!

"Engineering continues on the proposed Sulphidization-Acidification-Recycling-Thickening ("SART") circuit, and ancillary facilities. The new circuit, which will allow the processing of oxidized stockpiles is expected to increase the mine life at Don Mario by an additional 2-3 years and is expected to commence soon"

"• An evaluation of re-processing tailings is in progress to determine the viability of recovering gold from material deposited in the tailings impoundment since the commencement of production at Don Mario."

Underway tests show optimal oxides stockpile metallurgy by combining a Sulphidization Acidification Thickening Recycling process ("SART"), with heap leaching, and a Carbon-in-Column (CIC) circuit.
