Tinka drills 42 m of 165 g/t silver including 10 m of 354.7 g/t silver at northern extension of Zone 1, Colquipucro project, Peru

VANCOUVER, Feb. 21, 2012 /CNW/ - Tinka Resources Limited (the "Company"), (TSXV - TK; Frankfurt - TLD; Pinksheets -TKRFF), announces the results from three further drill holes testing the northern extension of Zone 1 on the Company's wholly-owned Colquipucro silver-zinc-lead property, west-central Peru. The holes were drilled on the easternmost and central section lines of the known resource.

The holes intercepted oxidized, banded, "zebra-stripe" sandstone and progressed into the underlying sedimentary breccia, greywacke, siltstone and fluidized sulphide unit. This unit is generally quite thin or non-existent elsewhere in the resource area, but each of holes 16 to 19 intercepted many 10's of metres of this lithologic assemblage, not reaching the underlying Pucura limestone. Also, the mineralization in this unit is more oxidized than in holes further downslope or west from here. All holes intercepted the high grade veins/faults/gossan zones within the sandstone roughly perpendicular to the dip of the hole, while the intervening fracture-controlled mineralization in the sandstone was intercepted at about 45 degrees to the inclination of the drill hole, on average. The orientation of the mineralization within the underlying sedimentary breccia is not clear, however, narrow zones of intense oxidation suggest that the mineralized structures in the overlying sandstone may penetrate the underlying unit.  The mineralization in holes 17 and 18 remain open at depth and 19 was abandoned at 129 m due to drilling conditions.

Significant mineralized intervals, using a 15 g/t Ag cut-off, are shown below:

All diamond drilling has been performed using HQ and NQ diameter drill rods. All core has been logged and split on site under the supervision of Tinka geologists, with sampling done on two metre intervals. All the samples have been transported by Company staff to SGS Laboratories in Lima, Peru for assay by multi-acid digestion method. Analytical standards and blanks were routinely introduced in the sample suites sent to the laboratory, and samples that exceeded their respective threshold levels for Ag, Zn and Pb were re-assayed by specific atomic absorption techniques.

Mr Carter said: "These results are extremely positive as they confirm that the mineralization continues north and is open at depth, giving the potential of increasing the size of the resource. Drilling is continuing at Zone 1 testing the northern extension. The Company has elected to withdraw from its option over the Tibillos copper porphyry property due to the drill results. In doing so, the Company will be able to concentrate its efforts and resources into the Colquipucro project."

The Company's Qualified Person, John Nebocat (P.Eng.), who has recently visited the drill site to observe the core from the holes reported in this news release, has reviewed and approved the contents of this news release.
