The work completed by SGS was a first-pass bench-scale scoping study based on a small bulk sample of historical drill core, being 100 kg. It is the first metallurgical test-work completed at Panuco and demonstrates robust gold, silver, lead and zinc recoveries above 90% are achievable.
The metallurgical test work supports both bulk flotation flow-path and sequential flotation flow-path, with the bulk floatation flow-path producing a single gold, silver, lead and zinc rougher concentrate (15 minutes of floatation and 23% mass pull) with 697 g/t silver, 0.97 g/t gold, 1.67% zinc and 0.58% lead and recovering 96.2 % of the silver, 93.6% of the gold, 96.5% of the zinc and 92.1 % of the lead.
This is an attractive processing option for silver-rich but base metal-poor material.
