This is the Company's second PEA completed within the
Highlights of the PEA, with a base case silver price of
- After-Tax NPV (using a discount rate of 5%) of
$413 Million with an After-Tax IRR of 29% (Base Case); - 13-year mine life producing a total of 110.3 Million payable silver equivalent ounces ("AgEq"), consisting of 68.0 Million silver ounces, 221,700 gold ounces, 22.8 Million pounds of copper, 144.1 Million pounds of lead and 242.2 Million pounds of zinc;
- Initial capital costs of
$221 Million , including$29 Million in contingency costs, over an expected 18 month build, additional expansion capital of$137 Million , and sustaining capital costs of$6 Million over the life of mine ("LOM"); - Average LOM operating cash costs of
$9.50 /oz AgEq, and all in sustaining costs ("AISC") of$9.68 /oz AgEq - Average annual production of 8.8 Million AgEq oz in years one through twelve;
- Approximately 3/4 of LOM production is from four open pits containing oxide mineralization and approximately 1/4 is from a separate open pit which contains only sulphide mineralization.
"We're pleased to file our technical report for the Los Ricos North PEA which provides the details of the strong economics of the project – showing average annual production of 8.8 Million AgEq oz at a first quartile AISC of

3. | The Inferred Mineral Resource in this estimate has a lower level of confidence than that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve.
