In March 2009 Argent drilled five diamond holes at Sunny Corner to obtain samples for metallurgical (flotation) testing. Testing has now been completed and the results indicate that recovery of over 97% of contained base and precious metals was readily achieved to a 30% by weight bulk concentrate grading 20.5% Zn, 8.8% Pb, 2.3% Cu, and 180g/t Ag. Attempts, including fine grinding to 6 microns, were unsuccessful in achieving saleable zinc, copper or lead concentrates with acceptable recoveries.
The silver, lead, zinc and barite resources at Kempfield contain 13 million ounces of silver They comprise a potentially heap leachable resource containing, at a 60 g/t silver only cut off, 8.7 million ounces within 70 metres of the surface and a sulphide resource containing ,at a 100g/t silver equivalent cut off, 4.4 million ounces between 70 and up to 190 metres from the surface.
