Wallbridge announces positive results from Pre-Feasibility Study of Broken Hammer Project in Sudbury
TORONTO, Oct. 16, 2012 /CNW/ - Wallbridge Mining Company Limited (TSX: WM, FWB: WC7) ("Wallbridge") today announced positive results from a prefeasibility study completed on its Broken Hammer copper and platinum group metal project in Sudbury, Ontario. The prefeasibility study was prepared by Genivar Inc. and demonstrates the viability of the project as an open pit mine, with the ore treated at a custom mill facility.
Prefeasibility study highlights
- Estimated Earnings Before Interest, Taxes, Depreciation, and Amortization (EBITDA) of $8.4 million or $42.60 per tonne of ore
- Estimated total capital costs (CAPEX) for the project of $1.9M
- Estimated pre-tax Net Present Value (NPV) of $6.03M using an 8% discount factor and $3.50USD per pound of Copper and $1,600USD per ounce of Platinum and CAD/USD of 1.00
- Estimated ore production rate of 750 tonnes of Cu-Ni-PGE ore per day similar to the 2011 bulk sample production rate
- Estimated Mine life of 12 months
- Estimated Operating Costs (OPEX) of $131.99/per tonne of ore
All dollar amounts are in Canadian currency. A final version of the prefeasibility study will be filed on SEDAR within 45 days as required.
"We are very encouraged by the positive results of the prefeasibility study" said Marz Kord, President and CEO of Wallbridge Mining. "The prefeasibility suggests that the Broken Hammer project has the potential to become economically viable and generate positive cash flow. What's more encouraging is that the deposit remains open for expansion to the west and to depth".
Mr. Kord added, "The footwall-style Broken Hammer project is in a large land package on the northern rim of the Sudbury basin within a 9-kilometer strike length of very similar geology with extremely strong prospects."
Broken Hammer Project Description
The Broken Hammer project is planned to be an open pit operation used for the extraction of approximately 196,000 tonnes of in-pit Cu-Ni-PGE mineral resources utilizing the services of surface mining contractors. The ore is planned to be sampled for metal accounting through a sample tower on-site prior to being transported to an off-site facility for processing. The prefeasibility study assumes the production will commence in early to mid-2013 and will be completed within 12 months of mining operation at an average daily rate of approximately 750 tonnes of ore during the 12-months of operation.
Summary of the Broken Hammer Updated Mineral Resource Estimate
An updated resource estimate prepared by Roscoe Postle Associates Inc. ("RPA") according to NI43-101 standards was filed as a technical report on the property on August 1, 2012.

|BROKEN HAMMER MINERAL RESOURCE|
|Category||Tonnes||Cu (%)||Ni (%)||Pt (g/t)||Pd (g/t)||Au (g/t)||Ag (g/t)|
As part of the prefeasibility study, RPA prepared an in-pit mineral reserve estimate based on a global mining recovery of 95% and 5% dilution (at zero grade). Table 2 below summarizes the in-pit reserve.

|Category||Tonnes||Cu (%)||Ni (%)||Pt (g/t)||Pd (g/t)||Au (g/t)||Ag (g/t)|
|Waste Rock||1,710,770 tonnes|
Summary of Capital Cost Estimates (CAPEX)
The total capital cost to build the Broken Hammer open pit is estimated to be $1.9M. Specific details are as follows:
|Category||Capital Cost ($K)|
|Contingency @ 15%||250|
Summary of Mine Operating Cost Estimates (OPEX)
The total mine operating cost including G & A and start-up development,
all processing facility charges and penalties and 1.5% royalty are
estimated to be $25.95 million, which represents $131.99 per tonne of
ore. Specific details are as follows:
|Mine Operating Costs||$/Tonne||$/Tonne|
|Drilling/ Blasting / Loading & Hauling||$8,334,000||$4.37||$42.39|
|SUB-TOTAL MINING (DIRECT)||$4.37||$42.39|
|General & Administrative||$1,263,000||$0.66||$6.42|
|Crushing & Sampling||$2,162,000||$1.13||$11.00|
|Haulage to custom mill||$1,965,000||$1.03||$10.00|
|TOTAL MINING & TRANSPORTATION COSTS||$7.19||$69.80|
|Milling, Smelting, Refining Costs & Charges||$12,227,000||$6.41||$62.00|
|TOTAL PROCESSING COSTS||$6.41||$62.19|
|TOTAL OPERATING COSTS||$13.60||$131.99|
Economic Analysis & Sensitivity
The parameters used for the prefeasibility study are as follows:
The 12-month project generates an EBITDA of $8.4M and a pre-tax Net Present Value (NPV) of $6.03 M discounted at 8%. The payback period would be 8.0 months. Below are the details of the economic analysis:
|Crushing & Hauling||3,933,000||20.00|
|Milling, Smelting, Refining & other charges||12,227,000||62.19|
|PROFIT BEFORE ROYALTY||$8,682,000||$44.16|
|Royalty @ 1.5%||307,000||1.56|
The sensitivity analysis on the base case pricing scenario uses variations of +/- 15% from the base case in revenues for copper, platinum, and other factors that could have a significant effect on the project. Below is the sensitivity analysis chart for the Broken Hammer project based on the variations in those significant parameters:
The project is most sensitive to US/C$ exchange rate as well as project operating costs.
Cautionary Notes regarding the prefeasibility study
The Broken Hammer pre-feasibility study was prepared to broadly quantify the Broken Hammer deposit's capital and operating cost parameters, and to further the development of this footwall-style Cu-Ni-PGE project. It was not prepared for use as a valuation of the Broken Hammer deposit, nor should it be considered to be a final feasibility study. The information contained in the Broken Hammer pre-feasibility study reflects various technical and economic conditions at the time of writing and is based on the successful results of the 2011 bulk sample. These conditions can change significantly over relatively short periods of time. The achievability of life of mine plans, budgets and forecasts are inherently uncertain. There can be no assurance that the potential results contained in the Broken Hammer pre-feasibility study will be realized. Readers are cautioned that the assumptions used in the preparation of the Broken Hammer pre-feasibility study, although considered reasonable at the time of preparation, may prove to be imprecise and, as such, undue reliance should not be placed on them.
