Broken Hammer Resource Property (98.5% Wallbridge, 1.5% Xstrata Nickel royalty interest) As a result of the restructuring on the Xstrata Nickel 4X Joint Venture, Wallbridge Mining acquired Xstrata Nickel's minority interest in the six claims surrounding the Broken Hammer resource. The Broken Hammer resource is a surface zone of vein-and vein stockwork-hosted copper-PGE mineralization located about 1.6 kilometres into the SIC footwall behind the Wisner embayment on the North Range of the SIC. An initial mineral resource estimate was completed by David Rennie, P.Geo.of Roscoe Postle Associates Inc. ("RPA") for the Broken Hammer Zone on the Wisner Property in November 2005. The total Inferred Mineral Resource, as estimated by RPA to NI-43-101 standard, is 251,000 tonnes at a grade of 3.80g TPM/t (1.56 g/t Pd, 1.62 g/t Pt, and 0.61 g/t Au), 1.00% copper, and 0.10% nickel. Metallurgical test work carried out at SGS Minerals Services on a 175 kilogram composite of Broken Hammer mineralization showed excellent recoveries of copper (Cu), platinum (Pt), palladium (Pd) and gold (Au). The work program also confirmed the presence of very coarse grained platinum minerals and demonstrated the amenability of Broken Hammer mineralization to a simple gravity/flotation circuit. Total metal recoveries were predicted at 91.8% of the copper, 89.4% of the platinum, 77.8% of the palladium, and 83.7% of the gold. A very saleable gravity concentrate was produced, with a grade of over 3700 g/t PGE (Pt+Pd+Au), containing 67% of the total platinum. A further 22% of the platinum was recovered in the flotation concentrate, which also contained 21.6% copper and 1.35% nickel. This would be an ideal feed for one of the South African platinum smelters currently treating high chromite UG2 ores, as it is reasonably rich in sulphide and platinum group minerals ("PGM"), but low in chromite. The excellent base metal and platinum group metal recoveries led Wallbridge to commence a Preliminary Economic Assessment ("PEA") or Scoping Study on the Broken Hammer deposit in November 2006. The PEA will be prepared under National Instrument 43-101 Standards of Disclosure for Mineral Projects. Wardrop Engineering was retained to lead the study and prepare the mining component whereas DRA Americas and AMEC were retained to prepare the milling and waste management components, respectively, and SGS Mineral Services was retained to conduct confirmatory test work following up on the recently completed gravity and flotation tests. The Scoping Study will include design of the open pit mine, on-site milling facilities, waste rock and tailings management and completion of environmental baseline studies within several proposed potential tailings management sites. Capital and operating cost estimates will be prepared and included in a cash flow analysis and economic evaluation. A sensitivity analysis will be conducted using conservative metal prices as the base case. |
