Tinka drills 48 metres grading 11.3 % zinc at South Ayawilca

STEP-OUT DRILLING EXTENDS MINERALIZATION STRIKE LENGTH BY 500 METRES

VANCOUVER, June 8, 2017 /PRNewswire/ - Tinka Resources Limited ("Tinka" or the "Company") (TSXV: TK) (OTCPK: TKRFF) is pleased to announce results of five additional drill holes from its 100% owned Ayawilca zinc project in central Peru. All five holes are from the South Ayawilca area.  Hole A17-063 has returned one of the best intersections of zinc mineralization at Ayawilca to date, 47.7 metres grading 11.3% zinc, also with high indium credits. Hole A17-063 lies 200 metres northeast of the South Ayawilca discovery hole A17-056, which intersected two high grade zinc sulphide zones including 17.9 metres at 11.6 % zinc and 51.9 metres at 10.1% zinc (see Table 1).   Drill results reported so far in 2017 have defined high grade zinc mineralization at South Ayawilca over a northeast-southwest strike length of 370 metres, connecting the South Ayawilca discovery area to the Central Ayawilca zinc resource.

Key Highlights

Hole A17-059:

• 0.8 metres at 37.5 % zinc, 0.5 % lead & 69 g/t silver from 50.3 metres depth (vein).

• 47.7 metres at 11.3 % zinc, 18 g/t silver & 313 g/t indium from 302.2 metres depth, including
• 9.8 metres at 17.4 % zinc, 28 g/t silver & 587 g/t indium from 303.3 metres depth; and
• 12.2 metres at 17.1 % zinc, 26 g/t silver & 495 g/t indium from 327.4 metres depth.

Hole A17-064:

• 0.5 metres at 15.6 % zinc, 11 g/t silver & 304 g/t indium from 269.9 metres depth; and
• 0.4 metres at 14.5 % zinc, 17 g/t silver & 39 g/t indium from 277.2 metres depth.

Hole A17-065:

• 19.3 metres at 4.7 % zinc, 7 g/t silver & 93 g/t indium from 219.5 metres depth, including
• 2.6 metres at 20.6 % zinc, 23 g/t silver & 529 g/t indium from 236.2 metres depth; and
• 26.6 metres at 3.6 % zinc, 4 g/t silver & 46 g/t indium from 266.4 metres depth; and
• 24.7 metres at 3.8% zinc, 5 g/t silver & 51 g/t indium from 307.3 metres depth.

Hole A17-066:

• 3.5 metres at 7.4 % zinc, 24 g/t silver & 111 g/t indium from 330.9 metres depth, and
• 5.0 metres at 11.3 % zinc & 37 g/t silver & 270 g/t indium from 345.0 metres depth;

Dr. Graham Carman, Tinka´s President and CEO, stated: "These latest drill results continue to show strong zinc mineralization in our step-out drill program at South Ayawilca. There now appears to be continuity of the zinc mineralization between South & Central Ayawilca, which could add an additional 500 metres of mineralization along strike extension to our existing resources. Massive to semi-massive sulphides occur throughout the mineralized sequence.  We are finding that the zinc mineralization is zoned around iron sulphides (mostly pyrrhotite with lesser pyrite) which may also host tin mineralization (note: tin assays are pending). We have also encountered an important northeast-trending fault, and can confirm that post-mineral movement has displaced mineralization laterally which opens additional exploration opportunities."

The Company has now released results from eleven drill holes of an estimated total of 30 holes planned for 2017.  Seventeen holes have been completed. There are currently two rigs drilling at South and Central Ayawilca focussing on resource expansion and connection of these areas (see drill map, Figure 1).  A third drill rig is currently testing the possible extensions of West Ayawilca.  A fourth rig has started at Zone 3, a new area located 700 hundred metres northeast of the existing zinc resource area (see Figure 2). 

Zinc mineralization is associated with gently dipping, massive to semi-massive, sulphide replacements of carbonate and clastic sediments.  Minor veins are also noted.  True thicknesses of the zinc intersections are estimated to be at least 85% of the downhole thickness, except where otherwise noted in Table 1. All significant results of the 2017 program are summarized in Table 1 with the strongest intercepts in bold text.

Notes on sampling and assaying:
Drill holes are diamond HQ or NQ size core holes with recoveries generally above 80% and often close to 100%.  The drill core is marked up, logged, and photographed on site.  The cores are cut in half at the Company's core storage facility, with half-cores stored as a future reference.  Half-core is bagged on average over 1 to 2 metre composite intervals and sent to ALS laboratory in Lima, an ISO 9001:2000-registered laboratory, for assay in batches.  Standards and blanks are inserted into each batch prior to departure from Tinka'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 (MS) using multi-acid digestion. Samples assaying over 1% zinc, lead, or copper are re-assayed using precise ore-grade AAS techniques.
