Indicated resource of 6.5 million oz Silver, 149 million lbs Lead and 490 million lbs Zinc
Inferred resource of 1.3 million oz Silver, 25 million lbs Lead and 144 million lbs Zinc
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 04/08/09 -- Trevali Resources Corp. ("Trevali" or the "Company") (CNSX: TV)(PINK SHEETS: TREVF)(FRANKFURT: 4TI) is pleased to announce results of the first independent National Instrument 43-101-compliant resource estimate for the three Magistral zones at the Santander Silver-Lead-Zinc Mine project in Peru - confirming three significant polymetallic deposits.
The resource estimates on the Magistral North, Central and South deposits were conducted by and under the supervision of Kevin Palmer P.Geo., an independent qualified person employed by Golder Associates Ltd. of Vancouver, Canada and reviews a total Indicated Mineral Resource of 5,298,000 tonnes with an average grade of 3.34% zinc, 1.27% lead and 38 g/t silver (using a 2% ZnEQ(i) cut-off grade - that is the nominal base case estimated grade of material that can be mined and processed considering all applicable costs) - for a contained metal inventory of 390 million lbs. zinc, 149 million lbs. lead and 6.5 million oz. silver in the Indicated category (Table 1).
An Inferred Mineral Resource of 2,244,000 tonnes grading 2.92% zinc, 0.50% lead and 18 g/t silver was also reviewed in the three deposits using the same cut-off grade - for contained metals of 144 million lbs. zinc, 25 million lbs. lead and 1.3 million oz. silver. The resource estimates for the three Magistral orebodies are based on 104 diamond drill holes (with a combined length of approx. 20,600 metres) completed by Trevali over a 12 month period ending late-2008. All three Magistral bodies remain open at depth and to the East (Figure 1).
Additionally, a further 100 million contained lbs. of zinc are estimated to be present in the 1,656,000 indicated tonnes grading at 2.74% zinc (using a 2.0% zinc cut-off grade) at the Santander Tailings Impoundment (Table 2). The Santander Tailings resource estimate is based upon 55 percussion drill holes totalling 910 metres.
"We are very excited with the initial resource estimate for the three Magistral deposits as it exceeds the Company's resource threshold and provides sufficient confidence to enable reactivation of mining operations at Santander," states Mark Cruise, Trevali's President and CEO. "We are confident that Trevali is strongly positioned to advance to production based on these new deposits and the substantial pre-existing infrastructure in place at the project, including our own low-cost power supply from the Tingo hydroelectric generating station."
"The Company's track-record speaks for itself, in a compressed timeframe and under less than ideal market conditions the team has advanced Santander on all fronts - geological, engineering, metallurgical, power and permitting. We've drilled three targets and have delineated substantial deposits in the Magistral zones, all of which remain open and have very significant depth potential," further states Dr. Cruise.
