Argentex Mining Corporation (TSXV:ATX, OTCQB:AGXMF) announced results from preliminary metallurgical testing at their Pingüino Silver-Gold Project in Argentina.
As quoted in the press release:
- Preliminary heap leach column test work on the oxide samples indicated silver recoveries up to 81% and gold recoveries up to 69% with leaching times of up to 45 days. Silver and gold were still leaching when the tests were terminated, suggesting the potential for recoveries to increase with longer leaching periods.
- Bottle roll test work on oxide samples indicated recoveries up to 95% for silver and up to 94% for gold.
- Flotation of Marta Este and Marta Centro sulphide vein materials resulted in good deportment of the lead and zinc to the respective concentrates at potentially saleable grades.
Argentex’s President and CEO, Mike Brown, said:
The results of our first round of metallurgical testing at Pingüino are promising. We anticipate that future process optimization studies will improve recovery efficiencies and cost reduction benefits.
