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.

Prof. James Tour
AZoMining speaks with James Tour from Rice University about his team's exciting method that has the very real potential to recover valuable REE from three types of waste; electronic waste, coal fly ash and bauxite residue.
Craig Liddicoat from Flinders University speaks to AZoMining about his team's work on effective rehabilitation in post-mining ecosystems and whether it can set up a predictable trajectory of recovery. We also ask why ecosystem recovery is important in mining operations and the current limitations af
In this interview, Andrew Somers from SciAps Australia talks to AZoMining about the new Geochem Pro application for the Z range of handheld elemental analyzers, and the improvements that have been made to their technology over the last year.
