VANCOUVER, June 28, 2017
29.3 METRES GRADING 10.4 % ZINC INCLUDING 12 METRES AT 19% ZINC IN HOLE A17-069; AND 39.3 METRES GRADING 7.1 % ZINC INCLUDING 8 METRES GRADING 20.9 % ZINC IN A17-070
VANCOUVER, June 28, 2017 /PRNewswire/ - Tinka Resources Limited ("Tinka" or the "Company") (TSXV: TK) (OTCPK: TKRFF) is pleased to announce assay results of five recent drill holes from its 100% owned Ayawilca zinc project in central Peru. All five holes are from South Ayawilca and the extension of the Central Ayawilca areas, where zinc mineralization occurs in flat-lying sulphide bodies replacing carbonate and clastic rocks adjacent to a northeast trending fault. Holes A17-069 and A17-070 were drilled between two earlier drill intersections in holes A17-056 and A17-063 (see previous releases May 3, 2017 and June 8, 2017). These new results confirm the continuity of high grade zinc mineralization in two separate replacement bodies (mantos) at South Ayawilca over a strike length of at least 300 metres, with the lower sulphide manto believed to be continuous over a one kilometre strike from South Ayawilca to Central Ayawilca.
Key Highlights from the Five Recent Holes
Hole A17-069:
- 29.3 metres at 10.4 % zinc, 17 g/t silver & 278 g/t indium from 271.4 metres depth, including
- 12.1 metres at 19.1 % zinc, 25 g/t silver & 440 g/t indium from 287.3 metres depth;
Hole A17-070:
- 1.6 metres at 15.4 % zinc, 40 g/t silver & 529 g/t indium from 306.8 metres depth; and
- 39.3* metres at 7.1 % zinc, 13 g/t silver & 100 g/t indium from 317.5 metres depth, including
- 8.0 metres at 20.9 % zinc, 19 g/t silver & 265 g/t indium from 340.0 metres depth;
* includes 4.3 metres of no recovery assumed zero grade
Hole A17-068:
- 0.75 metres at 6.1 % zinc, 11.6 % lead & 210 g/t silver from 343.55 metres depth;
- 6.0 metres at 4.0 % zinc & 46 g/t silver from 382 metres depth;
Hole A17-062:
- 0.65 metres at 33.6 % zinc, 0.3 % lead & 166 g/t silver from 152.4 metres depth (vein);
Hole was lost prior to target depth at 313 metres
Hole A17-067:
- 8.6 metres at 2.7 % zinc & 39 g/t silver from 256.4 metres depth.

Dr. Graham Carman, Tinka´s President and CEO, stated: "We are extremely pleased with these latest results, which confirm continuity of very high grade zinc mineralization at South Ayawilca over at least 300 metres of strike. Zinc mineralization also remains open in several directions including to the south, east, and possibly to the west where the favourable stratigraphic horizon may rapidly deepen. Hole A17-068, drilled 350 metres along strike from A17-063, shows that the lower mineralized manto is a continuous replacement body and connects with Central Ayawilca. The Ayawilca sulphide system is zoned; high grade zinc occurs outward of bodies of iron sulphide (mostly pyrrhotite) which host tin mineralization. This zonation has similarities to the giant Cerro de Pasco base metals deposit 40 kilometres to the southeast. Drilling is continuing with step-out holes at West Ayawilca, along with new targets being drilled at Zone 3 and Chaucha."
The Company has released results of the first sixteen drill holes of an estimated planned ~30 holes for 2017. Twenty-four holes have so far been completed, with hole A17-080 now beginning, and many assays are pending for both zinc and tin. We currently have one drill rig testing extensions of the West Ayawilca resource (see Figure 1 and Figure 4). A second drill rig is drilling at Zone 3. The third rig is setting up at the Chaucha area, with the first hole in that area planned to test a high priority geochemical-geophysical target. A fourth drill rig was recently demobilized from South Ayawilca, allowing the Company time to complete assays as well as analyze and interpret the new data.
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. Table 2 is a summary of all drill collar information to date.
