VANCOUVER, Sept. 20 /PRNewswire-FirstCall/ -- Tinka Resources Limited (TSXv - TK; Frankfurt - TLD; Pinksheets - TKRFF). Mr. Andrew Carter, President, is pleased to report that the Company has staked 900 hectares, known as the Chunumayo Project, located in the Department and Province of Huancavelica, Peru. This new project has been identified by Tinka through the exploration alliance with Sierra Peru Pty Ltd. ("Sierra Peru") announced June 1, 2004. The Chunumayo project lies within the richly mineralized Castrovirreyna - Julcani mining district, 20 km south of the town of Huancavelica and 250 km southeast of Lima. The property is situated only 14 km from the Julcani Mine, which has produced in excess of 81 million ounces of Ag and 0.2 million ounces of Au, at grades of approximately 590 g/t Ag, 1.2 g/t Au, 0.9% Cu, 0.6% Pb, 0.5% Zn. Recent mapping and prospecting of the claim area discovered a series of low-sulphidation epithermal vein/stockwork occurrences developed within limestone of the Pucara Group and overlying Tertiary-age volcanic rocks. Both rock sequences are host to mineralization in the District. Extensive areas of silification, brecciation and alteration with associated veins were located and sampled. Twenty one grab samples taken within an area of 3.3 km by 1 km ranged from less than 0.2 g/t Ag to 595 g/t Ag and averaged 70 g/t Ag, less than 0.005 g/t Au to 2.4 g/t Au and averaged 0.2 g/t Au. Lead averaged 0.35% and Zinc averaged 0.8%. As a result of these initial anomalous results, the field crew has returned to the project to undertake further surface sampling. The Company also advises that no further work will be undertaken within the Demetrio Project area. Extensive sampling undertaken by Company personnel failed to confirm historic sampling results. The Company's Qualified Person, John Nebocat, P.Eng., has verified the contents of this news release but has not visited the Chunumayo property.
