Tinka Resources Limited ("Tinka and/or the "Company") trades in Canada on the TSX Venture Exchange under the symbol “TK”, Frankfurt – “TLD” (WKN AOB 884) and is quoted in the USA on the Pinksheets under the symbol “TKRFF”.Tinka's main project in Peru is the Colquipucro silver-lead-zinc project consisting of 46 contiguous mineral tenements covering an area of 10,234.85 hectares and located in the Department of Cerro de Pasco. The Company completed a 15-hole, 2,670m, Phase 1 diamond drill program in November 2007. All but one hole intercepted silver mineralization above cut-off grade and results included 60m grading 135 g/t silver, 44m grading 95 g/t silver from surface, 66m grading 83 g/t silver from surface, 10m grading 625 g/t silver, 8m grading 551 g/t silver, and 12m grading 4.4% zinc which is open at depth. The Company has now completed soil sampling, trenching, sampling of underground workings, IP and drilling which has identified a zone of mineralization that extends across an east-west strike of about 200m, a width of up to 500m north-south and to a depth ranging from 100m to 200m.A recently completed independent NI43-101 report determined an inferred silver resource of 20.3 million ounces with an immediate potential contiguous target for up to a further 2 million tonnes at similar silver grades. See April 24, 2008 News Release for details of the report or click on NI43-101 to view a complete copy of this report.Initial preliminary metallurgical test work has provided positive results including the following highlights: silver recovery ranged from 90 to 97% with cyanide consumptions of 3.5 to 8.0 kg/t after leaching for 72 hours, silver leaching kinetics were extremely fast for both composites, and although reagent consumption was moderate to high the leaching time was extremely rapid, suggesting further test work may allow cyanide consumption to be reduced with only a small loss in recoverable silver.
