Vancouver, Canada – Tinka Resources Limited (“Tinka” or the “Company”) (TSXV: TK) (OTCPK: TKRFF) is pleased to announce assay results of five new step-out drill holes at its 100%-owned Ayawilca zinc project in central Peru. Three holes were drilled at the South Ayawilca discovery area, with one hole drilled at West Ayawilca (A17-074). Hole A17-073 was drilled at Zone 3, the first hole into this new target.

Holes A17-071 and A17-075 both intersected significant thicknesses of high grade zinc and have extended the footprint of the South Ayawilca discovery by 200 metres to the southeast, where zinc remains open and untested. Hole A17-072 at South Ayawilca intersected high grade silver with moderate grade zinc-lead mineralization adjacent to an important northeast-trending fault, which is a new style of mineralization observed at Ayawilca, This new high-grade silver discovery opens up additional exploration opportunities. Three rigs continue to turn at the project on multiple fronts.

Key Highlights

Hole A17-071 (South Ayawilca):

  • 22.8 metres at 8.4 % zinc, 0.8 % lead, & 35 g/t silver from 327.2 metres depth, including
    • 12.6 metres at 11.6 % zinc, 0.9 % lead, & 35 g/t silver from 332.4 metres depth;

Hole A17-072 (South Ayawilca):

  • 11.5 metres at 2.9 % zinc, 2.3 % lead & 781 g/t silver from 294.5 metres depth, including
    • 2.0 metres at 5.6 % zinc, 5.5 % lead & 3167 g/t silver from 302.0 metres depth;

Hole A17-075 (South Ayawilca):

  • 20.8 metres* at 5.0 % zinc, 11 g/t silver & 44 g/t indium from 359.0 metres depth, including
    • 3.5 metres at 10.2 % zinc, 17 g/t silver & 96 g/t indium from 376.3 metres depth;
      * includes 1.7 metres of no recovery assumed zero grade

Hole A17-074 (West Ayawilca):

  • 2.2 metres at 31.0 % zinc, 0.1 % lead & 138 g/t silver from 71.4 metres depth (vein), and
  • 0.7 metres at 18.3 % zinc & 38 g/t silver from 148.0 metres depth (vein);

Hole A17-073 (Zone 3):

The first hole at Zone 3, drilled 700 metres east of the existing East Ayawilca Inferred Resource, was completed to a depth of 710 metres. Replacement sulphide mineralization was encountered, mostly pyrite with minor sphalerite, over a 15-metre interval near the base of the carbonate sequence which hosts mineralization elsewhere. At Ayawilca, pyrite occurs on the margins of the zinc mineralization, so we interpret this as an indication that significant zinc mineralization may be close by. A follow-up hole (A17-081) is in progress, with one more hole planned for Zone 3 in this program.

See drill hole and zinc grade-thickness maps (Figures 1 and 2), and a South Ayawilca cross section (Figure 3).

Dr. Graham Carman, Tinka´s President and CEO, stated: “We are very pleased with these new drill results. The zinc discovery at South Ayawilca continues to expand southward, and remains open in several directions (see Figure 2). Hole A17-075 indicates that zinc may be thickening to the south on that section. The high-grade silver (zinc-lead) discovery in A17-072 is also exciting as it opens potential for additional bonanza-grade mineralization along the South Ayawilca Fault, which is largely untested. High-grade silver (zinc-lead) mineralization occurs with sulphides as cavity fillings in recrystallized limestone with abundant quartz-carbonate alteration, quite different to the massive sulphide mineralization associated with the high-grade zinc.”

Dr. Carman continued: “We are continuing to test zinc targets at the project and expand the drilling effort. Step-out holes are taking place at West and South Ayawilca, with new targets being drilled at Zone 3 and Chaucha.
The drilling at Zone 3 is progressing well. Indications are that a significant zinc sulphide system could be nearby. Zone 3 is a large target area covering more than 1 km2, and several holes will be needed to evaluate the full potential of that area.”

True thicknesses of the zinc intersections are estimated to be at least 85% of the downhole thickness, except where otherwise noted in footnotes to 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.

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 either ALS or SGS laboratories in Lima 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.

Both resources are open for expansion (May 25, 2016). The Silver Zone at Colquipucro, 2 km north of the Zinc Zone, has an Indicated Mineral Resource of 2.9 Mt at 112 g/t silver for 10.4 Moz silver and an Inferred Mineral Resource of 2.2 Mt at 105g/t silver for 7.5 Moz silver hosted by oxidized lenses between the surface and 80 metres depth (Feb. 26, 2015).
