Vancouver, Canada - Tinka Resources Limited (“Tinka” or the “Company”) (TSXV: TK) (OTCPK: TKRFF) is pleased to announce results of the first four holes of its current drill program at the Ayawilca zinc project, central Peru. All four holes have intersected high-grade zinc sulphide mineralization over substantial thicknesses. Tinka continues to prove the large scale zinc potential of Ayawilca.

Key drill results:

West Ayawilca area:
  • A14-22: 148.5 metres at 4.3% zinc from 170.0 metres depth, including 32.8 metres at 7.4% zincfrom 211.2 metres depth, and 31.0 metres at 6.3% zinc from 283.5 metres depth;
  • A14-20: 2.2 metres at 21.0% zinc from 164 metres depth; and 34.15 metres at 5.3% zinc from 179.85 metres depth, including 12.0 metres at 10.5% zinc from 179.85 metres depth; and 42 metres at 4.3% zinc from 268 metres depth;
  • A14-19: 144.9 metres at 3.9% zinc from 184.0 metres depth, including 18.0 metres at 7.1% zincfrom 250 metres depth;
East Ayawilca area:
  • A14-21: 19.6 metres at 5.7% zinc from 164.0 metres depth, including 6.0 metres at 10.2% zincfrom 166.0 metres depth.

Three of the holes at West Ayawilca (A14-19, A14-20, A14-22) were collared within 150 metres of a previous Tinka drill hole, A13-05, which intersected 213 metres at 5.3 % zinc from 130 metres depth (see Figures 1 and 2). The fourth hole (A14-21) targeted a previously untested geophysical magnetic anomaly at East Ayawilca and also intersected significant zinc mineralization. A 1% zinc cut-off grade over 6 metre intervals was used by the Company. Credits of lead (0.1-0.4%) and silver (10 to 20 g/t Ag) typically accompany the zinc mineralization. The mineralized rock is interpreted from drill core measurements to be generally gently-dipping. The true widths of the intercepts are believed to be at least 75% of the down-hole widths.

Dr. Graham Carman, Tinka’s President and CEO, stated: “These results from the first four holes in the current drill campaign are very significant, with all holes intersecting strong zinc sulphide mineralization over substantial vertical thicknesses. At West Ayawilca we are starting to see definition of the zinc mineralization around A13-05 with good probability of continuity of mineralization between holes covering a surface area of approximately 200 metres (north-south) by 130 metres (east-west). Mineralization remains open, and drilling is continuing.”

“At East Ayawilca, one kilometre to the east, the first hole drilled to test a geophysical anomaly (A14-21) intersected significant zinc mineralization over a 20 metre interval. We await assays for an additional hole, A14-24, which has just been completed. Further holes are planned at East Ayawilca in the current campaign as we believe this area has large scale zinc potential. It is very exciting that Tinka is intersecting zinc mineralization in two separate areas at Ayawilca, with a number of other targets including Central Ayawilca yet to be adequately followed up (e.g., drill hole A12-08 intersected 36.5 metres at 6.5% zinc in 2012).”
“Tinka is now approximately midway through the current drill program at Ayawilca, with two drill rigs operating. Seven holes have now been completed with assays awaited for three additional holes. Drilling will continue until mid-December, when operations will close down for Christmas and New Year. This will allow the Company time to compile and interpret results, and plan the 2015 drill programs.”


Geology of the zinc mineralization

Zinc mineralization at Ayawilca occurs in the form of massive to semi-massive sulphide replacements of sedimentary rocks, with lesser vein-style mineralization. The sulphides consist of sphalerite, pyrite, and pyrrhotite (with minor galena, chalcopyrite, and arsenopyrite) generally accompanied by chlorite, carbonate, and sometimes magnetite. The host rocks are a sedimentary sequence consisting of sedimentary breccia, siltstone, shale and limestone up to 250 metres thick (“Oyon Formation”) overlain by sandstone around 150 metres thick (“Goyllar Group”) forming a barren cap to the mineralization, although the sandstone can host sporadic sulphide veins. Beneath the Oyon Formation, which dips gently to the east, lies a metamorphic rock known as phyllite (“Excelsior Group”) which is barren of zinc. Drill holes are generally stopped a few metres into phyllite, with the average hole depth being 395 metres so far. Drill holes are angled steeply between 60 degrees and 85 degrees to the horizontal. See Tables 1 and 2 for a summary of the drill results and drill collar information.

Gravity geophysical survey

To further assist with the drill targeting, a geophysical gravity survey is now underway at Ayawilca. The gravity survey should assist our geological team in identifying massive sulphide target zones that are not associated with magnetic anomalies, which has been our principal targeting tool in the program to date. An area of approximately 2 km2 will be covered with a 100 metre by 100 metre gravity point spacing. A surrounding area of approximately 9 km2 will be covered with 200 metre x 200 metre point spacing. The gravity survey is expected to be completed by the end of November 2014.

Colquipucro drill program

Drilling is continuing with one drill rig at the adjacent Colquipucro silver oxide project, located 2 kilometres to the north of Ayawilca (see Figure 3). Tinka is carrying out a 10-hole, 1,500 metre drill program consisting of infill and resource extension drilling. We expect the drill program at Colquipucro to be completed by the end of November, with results of the full program to be released by the end of January 2015.

About Tinka Resources Limited

Tinka is a junior resource acquisition and exploration company with projects in Peru. Tinka’s focus is on its 100%-owned Ayawilca and Colquipucro projects in the highly mineralized zinc-lead-silver belt of central Peru, 200 kilometres north of Lima. The Ayawilca project, located 40 kilometres from Peru’s largest historic zinc mine, Cerro de Pasco, has the potential to be a major zinc sulphide discovery. The nearby Colquipucro silver oxide project is a near-surface, sandstone hosted silver oxide deposit with a current inferred resource containing 32 million ounces silver with potential for expansion.

Notes on core sampling:

All holes are diamond cores with recoveries generally at or close to 100%. The drill core (typically HQ size) is marked up, logged, and photographed on site. The cores are then cut in half at the Company’s core storage facility with half-cores stored as a future reference. The other half-core is bagged on average over 2 metre composite intervals and sent to SGS laboratory in Lima for assay in batches. Standards and blanks are inserted into each batch prior to departure from the Company’s core storage facilities. At the laboratory, samples are dried, crushed to 100% passing 2mm, then 500 grams pulverized for multi-element analysis by ICP using multi-acid digestion. Samples assaying over 1% zinc, lead, or copper are reassayed using precise ore-grade AAS techniques.

Notes on assay results (see Table 1):

Zinc intersections have been calculated on the basis of a 1% zinc cut-off over 6 metre intervals.

Note: the mineralized rock is interpreted from drill core measurements to be generally gently-dipping. The true widths of the intercepts are believed to be at least 75% of the down-hole widths.

Note on drill hole data:

Eastings and Northings are based on the PSAD56/18S UTM datum. The coordinates for the current drill holes are col-lected via a hand-held GPS and are considered accurate to within a few metres. Drill hole locations from the previous programs were surveyed with a theodolite or determined by tape and compass from a known survey point. Elevations are taken from a digital topographic model of the project based on a number of known points and are considered accurate to within a few metres. Azimuth and dip measurements were taken using compass and inclinometer at surface. All holes from A13-10 onwards were down-hole surveyed; small variances in both azimuth and dip do occur down hole.
