-
- 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 (Figure 1 and Figure 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.
