Tinka Identifies New Area of Surface Mineralization at Colquipucro

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 13, 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 a new area of surface mineralization at the Company's 100% owned Colquipucro silver-lead-zinc project, west-central Peru.

The new area, called Colquicocha, lies 2 km SE of the recently identified Ayawilca zone (see press releases dated January 15th and February 28th, 2008) and approximately 3.75 km SE of Zone 1 that was drilled during 2007 (see press release dated December 13th, 2007). A recently completed independent NI43-101 report determined an inferred silver resource of 20.3 million ounces silver with an immediate potential contiguous target (see press release dated April 24 for details of the report).

At Colquicocha, nine channel samples ranging from 1 metre to 3 metres width, were collected from surface outcrops and old workings. Results returned values ranging from trace to 222 g/t silver, trace to 9.10% lead and trace to 8.0% zinc. Two contiguous samples from one underground working, taken perpendicular to the bedding in the sandstone, averaged 136 g/t silver, 5.86% lead and 4.82% zinc. About 300 metres SE from this working, a 3.0 metre wide sample taken from another working along a north-south trending, easterly dipping structure, assayed 146 g/t silver, 8.78% lead and 0.57% zinc.

Of interest, also, are two other sample sites located during reconnaissance exploration. The first one, about 300 metres south of the centre of the Ayawilca zone, yielded 55 g/t silver and highly anomalous lead over 8 metres, sampled obliquely across the bedding. Previous mapping has identified a NE-trending structure that passes through this site and projects towards some anomalous soil samples, a distance in excess of 400 metres. The other site, located about 1.3 km ENE from here, returned 64 g/t silver and highly anomalous lead and zinc over 15 metres width. This site is described as a "manto" in sandstone which hosts pyrite and iron oxides.

The Colquicocha zone is underlain mostly by sandstones and siltstones containing finely disseminated pyrite throughout. Other sulphide minerals have not yet been identified in the matrix of these rocks, but the highly anomalous soil sample results suggest they are there (galena, sphalerite). It is believed that this sequence of east-west structures could be a similar setting to the Zone 1 area just drilled, where faults served as conduits for reprecipitating and enriching the mineralization both along the faults and in intervening fractures.

The Company has now completed a grid sampling program and surface exploration to further delineate this new zone and samples are now at the laboratory in Lima. Results will be released as soon as they are available.

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