Tinka Identifies Continuation of Colquipucro Sandstone Host Rock

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 28, 2008) - Tinka Resources Limited (the "Company") (TSX VENTURE:TK)(PINK SHEETS:TKRFF)(FRANKFURT:TLD). Mr Andrew Carter, President, reports the results of a recently completed soil sampling survey conducted on two newly identified areas of surface mineralization (see press release dated January 15, 2008) at the Company's Colquipucro silver project located in west-central Peru.

A total of 920 soil samples were taken from a grid along 18.2 km of survey lines. The lines extend from Zone 1, which was recently tested with 15 diamond drill holes (see press releases dated August 28, October 2 and December 12, 2007), southwards over a distance of up to 2 km. Results returned values ranging from trace to 85 g/t silver, trace to 0.39% lead and trace to 4.9% zinc.

An area of coincident silver-zinc-lead anomalies exists between 1.5 km and 2.0 km southeast of Zone 1. This anomaly is about 1,000m long, east-west, by up to 400m wide, north-south. Of great significance here is that the anomaly is underlain by the same sandstone that hosts the mineralization at Zone 1. Also, the sandstone is cut by numerous east-west faults and fractures, similar to the structural pattern seen at Zone 1. Two highly altered areas were found and sampled by the Company's qualified person along such fault structure late in 2006 situated near the center of this large anomaly. A 4.0m wide rock sample from one outcrop yielded only slightly anomalous Ag but 0.14% Pb and 0.12% Zn. A grab sample taken of a siliceous and ferruginous "clinker" sub-crop, located about 50m NE of this site, assayed 129.5 g/t Ag, 0.21% Pb and 0.12% Zn.

Anomalous silver, zinc and lead values were also obtained in the valley immediately south of Zone 1 where some old trenches exist. Overburden is fairly thick here, but some signs of the Pucura limestone and the pyrite +/- sphalerite and galena-bearing breccia unit that sits between the limestone and overlying sandstone exists here. Further sampling is required to delimit this anomalous area.

The terrain is quite gentle, and fewer showings are exposed. The Ayawilca workings are located on narrow shear zones along the western end of this zone where they are truncated by a large northwest-southeast trending regional fault. The extent of this anomalous zone is quite encouraging as it covers about three times the area defined at Zone 1 so far.
