Tinka Drills 12 Metres of 4.22% Zinc and Intercepts Mineralization to the Northeast at Ayawilca Project, Peru
December 18, 2013 (Source: Marketwired) — Tinka Resources Limited (TSX VENTURE:TK)(PINKSHEETS:TKRFF)(FRANKFURT:TLD) (the “Company”) announces the analytical results for holes A13-10 to A13-13 and visual results for holes A13-15 to A13-17 drilled at the Company’s 100% owned Ayawilca project, located in west-central Peru. See table below for a list of significant mineralized intervals.
Mr. Carter said: “The Company is pleased with these intercepts of zinc mineralization as they continue to demonstrate the potential of the Ayawilca project. Of great interest are the visual results of hole A13-16 and A13-17 which were collared 570 metres to the northeast of hole A12-08. This is a significant step as it confirms the presence of mineralization a substantial distance from previous drilling.”
Hole A13-15 is located on section 333300E, about 100 m west of the significant intercept of 70 m of 4.8% zinc found in hole A12-08 (see press release dated Jan. 8, 2013.) Massive and semi-massive sulphides were intersected between 321.1 m and 344.4 m depth with locally moderate concentrations of sphalerite in a matrix dominated by pyrite and pyrrhotite.
Drill holes A13-16 and A13-17 were collared along section 333900E, about 570 m northeast of A12-08. Both of these holes targeted an area where old workings are located along mineralized fault structures that cut the overlying sandstone formation. In addition, this site is also along the western margin of large coincidental magnetic and chargeability (IP) anomalies measuring about 700 m east-west and 700 m north-south, respectively.
In hole A13-16 (-60 degrees north), semi-massive sulphides were intersected between 354.9 m and 359.1 m and consisted of sphalerite and pyrite associated with strong chlorite and moderate magnetite alteration. Semi-massive sulphides, consisting of weak to moderate sphalerite mineralization, accompanied by strong chlorite and moderate magnetite alteration occurs between 376.3 m and 394.1 m and again from 436.0 m to 436.4 m and from 440.6 m to 443.5 m. The massive pyrrhotite horizon found above the metamorphic basement rocks in many of the holes is absent here.
Semi-massive sulphides (pyrite and sphalerite), along with moderate chlorite and magnetite alteration, occur between 329.6 m and 352.6 m depth in hole A13-17 (-75 degrees north). Sphalerite, plus some galena, were found between 373.1 m and 378.9 m with the same style of alteration. Massive pyrrhotite, containing pyrite, sphalerite and lesser chalcopyrite, occurs from 380.1 m and 405.6 m depth.

Hole A13-12A (Section 333700E) intercepted large intervals of intense chlorite and argillic alteration admixed with sulphides. This may be an indication that another strongly mineralized plume, like that encountered in holes A12-08 and A13-05, may present nearby. This area is being considered for further drill testing.
Except for A13-13, all returned moderately to highly anomalous copper values near the bottoms of the holes.
The Company cautions that visual results for these holes are preliminary and the Company is waiting for assay results to determine the level of mineralization intercepted. Assay results for holes A13-14 to A13-17 are expected to be available in early January 2014.
Significant mineralized intervals using 15 g/t Ag, 1% Pb and 1% Zn as lower cut-off levels are shown below:
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.
