Aldridge Minerals Inc. Announces NI 43-101 Preliminary Economic Assessment Filed on SEDAR
The results of the PEA (previously announced on December 20, 2010), on the Company's Yenipazar gold, silver, copper, lead, and zinc deposit in central Turkey estimates production, capital and operating cost parameters along with project economics.
Highlights of the economic analysis:
Yenipazar Project Economic Indicators

- 10.0% discount $151 million
- Internal Rate of Return 23.2%
- Project Payback Period From Start of Production (years) 3.9
- Total Pre-Production Capital $198 million
- Total Sustaining Capital $45 million
- Life of Mine Average NSR Value ($/tonne) $57.27
- Life of Mine Average Operating Cost ($/tonne) $29.65
Average Diluted and Mine Recovered Resource Grades
- Au 1.02 g/t
- Ag 31.6 g/t
- Cu 0.29%
- Pb 1.09%
- Zn 1.43%
Average Annual Payable Life-Of-Mine Production
- Au 23,700 oz
- Ag 1,136,000 oz
- Cu 9.7 million lbs
- Pb 36.8 million lbs
- Zn 36.5 million lbs
Conclusions and Recommendations
P&E concludes that the Yenipazar Project has favourable economic potential as an open pit mine producing copper, zinc and lead concentrates containing quantities of gold and silver. The base case economic analysis contemplates an average life-of-mine strip ratio of 4.5:1 (including the pre-stripping), a 5,700 tonnes per day mill feed rate and a 12 year mine life. Pre-production capital expenditures, including contingencies, are estimated to be $198 million.
The Yenipazar project has an estimated pre-tax net present value of $209 million at a 7.0% discount rate and an internal rate of return of 23.2% using base case metal prices of $2.95/lb Cu, $0.86/lb Zn, $0.90/lb Pb, $1,007/oz Au and $16.19/oz Ag (3 year trailing average prices at Nov 30, 2010).
Only 23.6 million Indicated tonnes of the diluted and recovered potentially mineable portion of the Yenipazar Project resource above an NSR cut off grade of $17.50 per tonne were used in the base case. The mine life average resource grades including mine dilution and losses are as follows: Au 1.02 g/t, Ag 31.6 g/t, Cu 0.29%, Pb 1.09% and Zn 1.43%
P&E recommends that the Company advance the project with extended and advanced technical studies in metallurgical, geotechnical and environmental matters with the intention to advance the project to a feasibility stage.
