Drills 16 Metres of 4.62% Zinc at Ayawilca Project, Peru
Vancouver, April 4, 2013 AEST (ABN Newswire) - Tinka Resources Limited (
CVE:TK) (TLD:FRA) (PINK:TKRFF), announces the results from drill holes, A13-02 and A13-03, at the Company's 100% owned Ayawilca project located in west-central Peru.
Hole A13-02 was collared at the same site as holes A12-08 and A12-09. The objective of this hole was to test the southern extension of the highly mineralized intercepts found in hole A12-08 (see press release dated January 8, 2013). Nearly continuous mineralization was intersected between 236 m and 328 m depth, but at slightly lesser grades.
Hole A13-03 was located at the same site as A13-01 (see press release dated March 12, 2013), 200 m east of A13-02.
Mr Carter said: "We are extremely pleased with these results as they continue to demonstrate the presence of strong zinc mineralization over a wide area within the 1,200 metre strike length IP anomaly (2010 and 2012 surveys) at Ayawilca. The application for further drill platforms at Ayawilca is in the advanced stages with the government authorities, and drilling will continue to test the geophysical conductors."
Semi-massive and massive sulphides occur interspersed with highly altered sediments of the Oyon formation which is host to the sulphide mineralization found at the Ayawilca project. The overlying Gollyar group sandstones host the silver resource at the Company's Colquipucro project located 1.5 km to the north. The sulphide minerals consist of varying proportions of pyrite, pyrrhotite and sphalerite with lesser galena, arsenopyrite and chalcopyrite. In general, pyrrhotite and chalcopyrite contents tend to increase with depth and to the east, but further drill testing is required to confirm any trends in mineral zoning.
The geometry of and controls to the mineralization are not yet fully understood, but a series of intersecting fault structures that underlie Ayawilca are believed to be the source conduits. The 3-D inversion anomalies (2010 and 2012 surveys) follow these structures closely. The irregular nature of this replacement style mineralization hampers any meaningful interpretation of the strike, dip and true thickness of the zone(s), intercepted in these and previously reported drill holes, at this time.
All diamond drilling has been performed using HQ diameter drill rods, reducing to NQ diameter if required. All core has been logged and split on site under the supervision of Tinka geologists with sampling done on nominal two metre intervals. All the samples have been transported by Company staff to SGS Laboratories in Lima, Peru for ICP analyses using multi-acid digestion. 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.
The qualified person for the Company's projects, Mr. John Nebocat (P.Eng.), V.P. of Exploration for the Company, has reviewed and approved the contents of this news release.
