SASKATCHEWAN – Foran Mining Corp. of Vancouver says metallurgical tests of material from its McIlvenna Bay volcanogenic massive sulphide deposit are positive. The tests were performed on a composite sample from the three main styles of mineralization – the copper-rich Copper Stockwork zone (CSZ), the zinc-rich Lens 2 massive sulphide zone, and the zinc- and copper-rich massive to semi-massive sulphide Upper West zone (UWZ) – at McIlvenna Bay.
Recoveries of 95% Cu, 85% Au and 77% Ag were measured in a copper concentrate grading 29% Cu, 6.4 g/t Au and 126 g/t Ag using material from the CSZ. Recoveries in material from the UWZ were 84% Cu, 60% Au and 50% Ag, again in a copper concentrate that graded 24% Cu, 6.4 g/t Au and 216 g/t Ag. A zinc concentrate from the same UWZ sample graded 54% Zn and recovery was 76%. Zinc recovery from Lens 2 material was 85% in a zinc concentrate grading 55% Zn; a bulk copper-lead concentrate was also made.
A discussion of the resents is presented in the news release dated June 20, 2012, and posted at ForanMining.com. The McIlvenna Bay deposit is located 65 km west of Flin Flon, MB.
