Tinka Announces Encouraging Results From Preliminary Metallurgical Test Work at the Colquipucro Silver Project, Peru

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 16, 2009) - Tinka Resources Limited (the "Company") (TSX VENTURE:TK)(PINK SHEETS:TKRFF)(FRANKFURT:TLD). Mr. Andrew Carter, President of Tinka, announces positive results from initial metallurgical test work at its 100% owned Colquipucro silver project in west-central Peru.

Highlights from this work include:

- 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;

- 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.

Test work was undertaken by Plenge Laboratories in Lima, Peru on two composite samples from the Colquipucro main mineralized zone ("Zone 1"). The samples were composited from 63 samples from two separate sections of pulps taken from diamond drill holes CDD6 and CDD13 that passed through Zone 1. Tests included head grade analysis, gravity separation and cyanidation. The samples were subjected to six conventional bottle roll techniques. Sample head grades averaged 79.7g/t Ag (CDD6) and 132.1g/t Ag (CDD13). Head grades for the metallurgical samples are in the same range as those of the recently calculated NI 43-101 inferred resource of 5.7 Mt at a grade of 111g/t silver (20.3 Moz silver) at Zone 1.

Mr. Carter states, "These first leach tests from the Colquipucro resource have demonstrated rapid leach kinetics and high silver recoveries. Such characteristics will have a positive impact on projected operating costs and financial return from any possible mining project at Colquipucro, and will provide a significant economic advantage to Tinka's shareholders. These results warrant detailed follow-up, and we plan to advance with additional testing."

The Company has also undertaken petrographic testwork and a structural analysis of satellite imagery, and is preparing for a late July field program to focus on the search for additional mineralization along the main structural zone.
