Mandalay Resources Corporation Delivers Positive Drill Results at the La Quebrada Copper-Silver Property, Chile

TORONTO, Aug. 9, 2011 /CNW/ - Mandalay Resources Corporation (“Mandalay“ or the “Company“) (TSX: MND, MND.WT) is pleased to announce the results of its recently completed 19 hole drill program at its 100% owned La Quebrada copper-silver property near La Serena, Chile. The results confirm and extend historically sampled and drilled mineralization described in its NI 43-101 compliant technical report on the property, dated April 14, 2010, and filed on www.sedar.com.

The 3,276 metre (“m“) program consisted of seventeen infill and step-out holes (2,932 m) in the Casa de Piedra target, and two exploratory holes (344 m) in the Leoncita North target (click here for La Quebrada District Geology Map). Assay results for the mineralized intervals intersected by these drill holes are summarized below in Table 1 (click here for complete results). All holes were drilled with HQTW diameter core that was logged by Mandalay geologists prior to being sawed and analyzed by the ALS laboratory in La Serena, Chile.

Brad Mills, CEO of Mandalay, commented, “These initial results confirm our geologic model and demonstrate that mineralization with potentially mineable widths and grades exists at both the Casa de Piedra and Leoncita North targets. It is particularly notable that the highest grade intercepts occur in the newly-discovered Leoncita North manto. Given these positive results, we believe additional drilling will be required to extend and improve confidence in the continuity of these mantos as well as enable us to complete an initial NI 43-101 compliant mineral resource estimate for both targets. To accomplish this, Mandalay is planning an additional $1.1 million, Phase 2 infill and extensional drilling program of approximately 5,690 metres that will commence following approval of an amended Environmental Impact Declaration which is expected to take four months to process.“

At Casa de Piedra, drilling intersected three principal copper-silver mineralized beds (“mantos“) ranging in thickness from 1 to 10 m with intervening intervals of thin, discontinuous mineralization (click here for Casa de Piedra Geology and Drill Hole Location Map and here for Casa de Piedra Cross Section A-A' and here for Casa de Piedra Cross Section B-B'). Mineralization in the mantos consists primarily of finely disseminated bornite and chalcopyrite hosted by calcareous sedimentary rocks of the Quebrada Marquesa Formation. Average copper grades of the manto intercepts in each hole range from 0.15% to 1.59% and average silver grades from 1 to 27 grams/tonne (“g/t“). Copper and silver grades are directly correlated.

The two holes drilled at the Leoncita North target intersected several thin (< 2 m) mantos and a single 2.2 m to 3.5 m thick manto that contains copper and silver values of 1.31% to 1.64% and silver values of 22 to 53 g/t. The principal manto at Leoncita North is hosted by a permeable, interflow horizon between porphyritic andesite flows (click here for Leoncita North Geology and Drill Hole Location Map and here for Leoncita North Cross Section A-A').
