Tinka Drills 60 Metres of 7.75% Zinc (Including 24 Metres of 13.85% Zinc and 46.5 g/t Silver) and 29 Metres of 7.05% Zinc at Ayawilca Project, Peru
VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 05/22/13 -- Tinka Resources Limited (the "Company") (TSX VENTURE: TK)(PINKSHEETS: TKRFF)(FRANKFURT: TLD) announces the results from holes A13-04 and A13-05, drilled at the Company's 100% owned Ayawilca project, located in west-central Peru. See table below for a list of significant mineralized intervals.
Hole A13-05 is located 435 metres west of hole A12-08, which intercepted 70 metres of 4.8% Zn (see press release dated January 8, 2013) and hole A13-04 is located 200 metres east of A12-08.
Mr Carter said: "We are extremely pleased with these significant intercepts as they continue to demonstrate the presence of strong zinc mineralization over a wide area, as well as a substantial increase in silver and copper near the eastern limits of our current drilling. Drilling will continue to test the geophysical conductors when the amended drill permit is granted."
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 pyrite, pyrrhotite and sphalerite with lesser arsenopyrite and chalcopyrite. Pyrrhotite (a magnetic iron sulphide) is more abundant at depth, along with increased chalcopyrite.
Hole A13-04 is the first to intercept any significant copper; a 10 metre interval averaged 1.07% Cu. Also of significance is the presence of silver in this interval, averaging 51.6 g/t Ag, within an 18 metre interval averaging 41.1 g/t Ag. The copper-silver intercept in hole A13-04 also contains highly anomalous arsenic plus moderately anomalous bismuth, and the significant silver intercepts in hole A13-05 are accompanied by strongly anomalous arsenic and copper with moderately anomalous bismuth; one section also contains highly anomalous lead.
The elevated copper values found in hole A13-04 may suggest some metal zoning as copper was often noted in the lowermost sulphide horizon(s) in the easternmost holes.
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 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.
