Tinka Releases Independent NI 43-101 Report for the Colquipucro Project, Peru


TSXV - TK; Frankfurt - TLD; Pinksheets - TKRFF

VANCOUVER, Oct. 18, 2012 /CNW/ - Tinka Resources Limited (the "Company"), (TSXV: TK) (Frankfurt: TLD) (OTCPK: TKRFF), announces the release of an independent NI 43-101 report for the Company's 100 percent-owned Colquipucro project, central Peru. Within this report are the details of the recently announced Zone 1 inferred silver resource calculation (see press release October 15, 2012). A copy of the full report is available on www.sedar.com and the Company's website www.tinkaresources.com. The report also details the results of the second round of metallurgical tests.

Mr Carter said: "We are extremely pleased with the details and recommendations in this report and will work towards commencing in-fill drilling at Zone 1 as soon as possible. This second round of metallurgical results provides the Company with further information as to the recoverability of the silver using a significantly lower cyanide concentration than used in the preliminary metallurgical test performed in 2009".

Four sets of drill core samples were tested by bottle roll and column leach in 2012 at the metallurgical division of SGS Laboratories in Lima, Peru. Composite samples with nominal head grades of 30, 60, 90 and 120 g/t Ag were selected. The bottle roll tests yielded recoveries of up to 84% Ag and the column leach tests up to 71% Ag after 72 hours. The preliminary bottle roll tests conducted in 2009 were done on two sets of drill core samples using significantly higher cyanide concentrations; these yielded recoveries of up to 90% and 97% Ag after 72 hours.

SGS Laboratories observed that in the bottle roll tests with only a 0.1 g/L cyanide concentration, extraction rates were fairly low; however, increasing the cyanide concentration to 0.5 g/L significantly increased the extraction rate for silver by 15%. Plenge Laboratories, for comparison, used cyanide concentrations of 2.0 g/L to 5.0 g/L.

The column leach test results closely match the extraction results observed in the bottle roll and benchmark test. As with the bottle roll tests, the higher grade composites also yielded the best silver extractions in solution.

SGS made several recommendations to further study and improve the vat leach tests, including use of different particle sizes, changing the irrigation rates, using larger volume of sample and varying the reagent concentrations.

The Company has permits in place to conduct the phase 3 drilling program. In-fill drilling will be done along gaps in the existing sections and along intervening sections spaced 50 m apart. The additional drilling should be adequate to upgrade the resources from the inferred to indicated category and core from the program will used for further metallurgical studies.

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

On behalf of the Board,
