PPX Mining Corp. Tests Sulfide Ore Processing

PPX Mining Corp., a Canadian company with operations in Peru, has initiated testing of sulfide ore processing from its Callanquitas Mine. A 2,222 DMT lot was processed, containing some oxidized material with significant gold and silver content. This test aimed to evaluate the amount of reagents needed for froth flotation processing.

The first batch yielded 142.05 tonnes of concentrate, which has been sold. The concentrate contained 13.40 gr/tn of gold and 1,274.31 gr/tn of silver, sold at US$1,944.54 per tonne. The recovery rates were 53.05% for gold and 75.50% for silver from the oxidized material. Ongoing tests aim to improve recovery from unoxidized sulfide. CEO John Thomas expressed optimism about revenue potential from transitional ore zones and further recovery improvements.
