TriMetals Mining Inc. Completes Very Positive NI 43-101 Compliant PEA at Gold Springs - Seite 2

The seven cases assessed in the PEA using the existing resource estimate show that the most robust case (Case 4), the one described at the beginning of this news release, is a 10,000 tonne per day ("tpd") open pit operation which extracts the gold and silver in a "heap leach" and recovers the metal through the Merrill-Crowe process.

The actual project would be designed such that it could be expanded if and when the resource estimate is expanded. Management believes that additional expansion of the resource estimate from the present base, with additional exploration, is very likely since resource drilling has only been carried out on a limited portion of the prospective areas.

The PEA used a base case gold price of $1,300 an ounce and a silver price of $21 an ounce. Each Case was also reviewed at lower gold prices and Case 4 returned a positive pre-tax NPV5% of $82million with a pre-tax 33%IRR even at a $1,000/oz gold price (with $21/oz silver price) and if gold rises in value, then the Case 4 pre-tax NPV5% doubles to $324M at a gold price of $1,900/oz. This demonstrates that Gold Springs is a very robust gold-silver project.

Case 4-Contractor Mining capex is $58M and operating costs are $8.16/ore tonne. The pre-tax payback period is approximately 1.5 years or approximately 2 years after tax. The Case 4 project produced an average of 48,000 oz AuEq* per year yielding an average pre-tax cash flow per year of $25M for 9 years with the first 3 years being $13M, $50M and $46M.

In the after tax Case 4-Contractor Mining Scenario the NPV5% drops to US$109 million from US$162 million and the IRR from 57.5% to 42%. This assumed a 25% Federal tax rate and 5% State tax for Nevada and Utah.
