TORONTO, Aug. 1, 2012 /CNW/ - Wallbridge Mining Company Limited (TSX: WM, FWB: WC7) ("Wallbridge") today announced the filing on SEDAR of independent NI 43-101 technical report completed by Rosco Postle Associates Inc. ("RPA") entitled "Technical Report on the Broken Hammer Project, Sudbury, Ontario, Canada" and dated July 27, 2012. This filing follows press release of June 19, 2012, which referenced the summary highlights of the new resource estimate.
Highlights of the technical report as previously announced in the Wallbridge's June 19, 2012 press release are as follows:
- The total Indicated Mineral Resource is 231,100 tonnes at a grade of 4.62 g TPM/t (1.90 g/t Pd, 2.01 g/t Pt, and 0.71 g/t Au), 0.92% copper, and 0.10% nickel and 6.35 g/t Ag.
- The deposit is open at depth with very little drilling below a depth of 100m.
The mineral resource estimate was prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum ("CIM") definition standards for Mineral Resources and Mineral Reserves. The resource model was prepared based on drill section interpretations using a cut-off of 1.00% copper equivalent (CuEq). 3D solids were constructed cooperatively between Wallbridge and RPA geologists, then reviewed and revised as necessary by RPA. The estimation employed statistical analysis and variography of metal values with construction of block models by domain. Block cell size was 5X5X5 metres with level 3 sub-celling and then re-blocked to 3X3X3 metres for the pit optimization runs. Grade interpolation to assign grade values to cells used Ordinary Kriging. No minimum mining width was used. The resource classification considered geological and grade continuity and was based on drill hole spacing.
Preliminary pits used to constrain the mineral resources reported were constructed using Whittle software based on the metallurgical and cost assumptions provided by Wallbridge and based on the 30,000 tonne bulk sample mined and processed in 2011. Mineral Resources are reported at a pit discard cut-off value of C$11 per tonne NSR value. NSR values were calculated based on metal prices, metallurgical recoveries, and all off-site payment terms and charges (including ore processing). The resulting NSR value in each block is then compared to operating costs for crushing and administration, within the pit shell (which includes consideration for the mining costs).
Mineral Resources were estimated using average long-term metal prices of US$3.00/lb Cu, US$9.00/lb Ni, US$750/oz Pd, US$1,600/oz Pt, US$ 1,300/oz Au, and US$ 20.00/oz Ag and a US$:C$ exchange rate of 1:1.
All aspects of the core sampling, assay procedures, and QA/QC program have been reviewed by RPA and were judged to be of industry standard and suitable for use in the estimation of Mineral Resources. Specific gravity determinations were completed by ALS Chemex on 300 sample pulps. Where data was not available, values were assigned based on a regression of specific gravity versus sulphur.
RPA is not aware of any environmental, permitting, legal, title, taxation, socio-political or marketing issues that are material to the statement of the mineral resource estimate.
Bruce Churchill, P. Geo. is the independent qualified person who prepared the mineral resource estimate. Marz Kord, President & CEO of Wallbridge has reviewed and approved the technical content of this press release.
