Hole A13-01 is located 200 metres east of holes A12-08 and A12-09, (see press release dated January 8, 2013) and 640 metres east of the initial discovery of semi-massive and massive sulphides in holes 52B and 53 (see press releases dated February 23, 2012 and November 21, 2011).
Mr Carter said: “We are extremely pleased with these results as they continue to demonstrate the presence of strong zinc mineralization 640 metres east of the original hole 53 discovery and within the 1,200 metre strike length IP anomaly (2010 and 2012 surveys) at Ayawilca. 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 pyrite, pyrrhotite and sphalerite with lesser arsenopyrite and chalcopyrite. Pyrrhotite (a magnetic iron sulphide) is more abundant at depth, along with increased chalcopyrite; a 20 meter interval containing elevated copper values yielded results of up to 0.9% Cu.
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 induced polarization (IP) and magnetic surveys conducted by CGG (formerly Fugro Ground Geophysics) on the Ayawilca project were completed during the first week of March. Preliminary results indicate that the conductors found in the 2010 and 2012 surveys continue further east for another 500 metres. The combined IP surveys from 2010 through 2013 will be compiled and subjected to 3-D inversion modelling; the results of these data will be announced once the Company receives the final report from CGG.
