Tinka Board Approves Further Work at the Colquipucro Silver Project, Peru

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 25, 2009) - Tinka Resources Limited (the "Company") (TSX VENTURE:TK)(PINK SHEETS:TKRFF)(FRANKFURT:TLD). The Board has approved an additional work program at its 100% owned Colquipucro silver project (6,679 hectares) located in west-central Peru.

Exploration by Tinka to date has identified an NI 43-101 inferred resource of 5.7 Mt at a grade of 111 g/t silver (20.3 Moz silver) at Zone 1, as reported in Tinka Press Release dated April 24, 2008. This work confirmed the volume of the host "zebra" sandstone at Zone 1 is limited by its geometry and fault bound nature and the mineral resources cannot be significantly increased by immediate work. Further silver mineralization needs to be found elsewhere on the property to enhance the overall prospectivity of Colquipucro and thus future work will focus on discovering silver mineralization away from Zone 1.

The bulk of mineralization discovered to date is associated with thin fractures developed in a zebra sandstone, a coarse grained, cross-bedded unit that lies adjacent to the main regional fault at Zone 1. This fault is interpreted to have provided pathways and structural preparation for the development of silver mineralization. The fault and immediate environs (approximately 300 metres into the footwall of the fault) provide the best opportunity for finding further silver resources at Colquipucro.

The Ayawilca zone, which lies 2 km south of Zone 1 along the main regional fault, was a focus of exploration by Tinka during 2008, with surface sampling and geological mapping completed. Strong east-west vein structures, similar in orientation to those mined historically in Zone 1, originate from the main fault and strike east. Shallow workings and adits follow these vein structures, where historic mining has exploited the highest grade mineralization. Sampling by Tinka geologists of soils, channels and rocks has returned trace to 549 g/t silver, trace to 4.1% lead and trace to 18.5% zinc along these vein structures. The prospective area at Ayawilca lies adjacent to the main regional fault, corresponds to the area of workings, and is underlain by the host zebra sandstone that may be up to 40m in thickness. This prospective area appears to be at least 400m long and 300m wide, although the subdued topography with limited outcrop make the magnitude difficult to determine. Further exploration work is justified.

It is concluded that significant silver mineralization at Colquipucro is controlled by the complicated main regional fault and that future exploration must be directed at testing this 12 km long structural trend within Tinka's permit area. A recommended work program prior to drilling will consist of: metallurgical testing of Zone 1 drill core, petrographic analysis, detailed airphoto interpretation on a 1 km corridor of the main fault and detailed follow-up mapping and sampling of the Ayawilca zone and any further targets. This work program will commence during March 2009.
