Tinka Identifies Further Surface Mineralization At Colquipucro

VANCOUVER, BRITISH COLUMBIA–(EMWNews – Aug. 20, 2008) – Tinka Resources Limited (the “Company”) (TSX VENTURE:TK)(PINK SHEETS:TKRFF)(FRANKFURT:TLD). Mr. Andrew Carter, President of Tinka, reports that the Company has identified further surface mineralization at the Company’s 100% owned Colquipucro silver-lead-zinc project, west-central Peru.

A total of 272 soil samples and 102 rock samples were taken along 5 survey line extensions of which 3 lines were located south of the Ayawilca zone (see press releases dated January 15th and February 28th, 2008) and 2 were placed at the Chaucha zone, located east of Zone 1. A recently completed independent NI43-101 report determined an inferred silver resource at Zone 1, using a cut-off of 30 g/t, of 5,669,853 tonnes at 111.4 g/t (20.3 million ounces) with an immediate potential contiguous target (see press release dated April 24 for details of the report). The soil sample results from the 2 lines at the Chaucha area, located between 0.5 km and 1.0 km east of Zone 1, that was drilled during 2007, (see press release dated December 13th, 2007) ranged from trace to 32.2 g/t silver, trace to 0.32% lead and trace to 0.37% zinc. The southern lines returned soil sample results ranging from trace to 59.9 g/t silver, trace to 0.18% lead, and trace to 2.7% zinc. Channel and rock chip samples ranged from 1 g/t to 549 g/t silver, trace to 0.57% lead and trace to 18.5% zinc. See attached plan of zinc surface geochemistry for location of zones.

At the Chaucha zone, iron and manganese-rich oxides, similar to the manto and replacement style mineralization observed in the Clinker zone immediately north of Zone 1 and in the underlying limestone, was observed by Mr. Nebocat during a visit to the property last July. Further soil and rock sampling plus detailed mapping is planned for this area.

Further sampling and detailed mapping has helped define the boundaries of the Ayawilca zone. A large normal fault, trending ENE-WSW, seems to form the southern boundary of the highly anomalous geochemistry and observed alteration and mineralization. Awayilca is underlain by a series of sub-parallel faults and fractures, trending roughly east-west which is similar to the structural pattern observed at Zone 1; these structures have been traced over a distance roughly 1,000m east-west by about 500m north-south, and the anomalous geochemistry in the soil and rock samples is more or less bounded within this area.

The President of Tinka, Mr. Andrew Carter says; “We are very pleased with the continuing discovery at Colquipucro of surface mineralization that is geologically and structurally similar to Zone 1, which was drilled in 2007, and identifying further potential drill targets.”

The application for the Phase 2 diamond drill program has been lodged with the relevant Peruvian authorities and the Company is waiting for approval.

The Company’s Qualified Person, John Nebocat (P.Eng.), has reviewed and approved the contents of this press release.

On behalf of the Board,

Andrew Carter, President & CEO
