ALBION OXIDATION PROCESS FUNCTIONING TO EXPECTATION LAS LAGUNAS GOLD AND SILVER PROJECT, DOMINICAN REPUBLIC
PanTerra Gold Limited (ASX: PGI) (PanTerra Gold or the “Company”), advises that the Albion oxidation circuit for the reprocessing of high grade refractory tailings from the Pueblo Viejo mine in the Dominican Republic, is operating at around 80% of oxidation levels established during pilot plant test work. The oxidation levels are increasing daily and expected to reach design levels later this week.
Temperatures from the exothermic reactions in the Albion tanks are within 5°C of the design range within the five tanks, and also increasing.
The oxidised slurry is being fed to the cyanide solution in standard CIL tanks, with gold and silver being adsorbed on to activated carbon in the tanks. Stripping the metals and production of doré bars to complete the extraction process should occur shortly.
Mr Brian Johnson, Executive Chairman of PanTerra Gold, said that the Company is nearing the successful conclusion of what has been an extremely difficult project development from both a technical and corporate perspective. However, if the Albion oxidation process meets expectations, as appears likely, the Intellectual Property that PanTerra Gold has gained could become the cornerstone for the Company to tap into significant business opportunities in Latin America, through participation in the development of mid-sized gold and base metal mining projects involving metallurgically complex refractory ores..
