Vancouver, Canada – Tinka Resources Limited (“Tinka” or the “Company”) (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to announce assay results for four new holes from the ongoing drill program at the Company’s 100%-owned Ayawilca project in central Peru. These results include hole A18-114, a step-out hole approximately 110 metres northwest of the West Ayawilca zinc resource, which intersected two high-grade zinc intervals in an area previously untested. Follow-up drilling is underway to test further extensions of this high-grade mineralization. Two drills are currently operating at West Ayawilca and Zone 3, with a third drill rig now mobilizing and expected to commence drilling by the end of April.

In addition to the West Ayawilca step-out hole (A18-114), three drill holes from the Zone 3 area are reported here (A18-110, 111, &112). Previously disclosed zinc intercepts in holes A18-110 & A18-111 in the Zone 3 area (including 5 metres grading 16% zinc from 173.8 metres) were reported on February 15, 2018.

Key Highlights
Hole A18-114 (West Ayawilca):

  • 19.3 metres at 9.2 % zinc, 0.2 % lead & 19 g/t silver from 300.0 metres depth, including
    • 4.0 metres at 16.2 % zinc, 0.2 % lead & 26 g/t silver from 300.0 metres depth; and
  • 14.4 metres at 12.8 % zinc, 1.9 % lead, 140 g/t silver & 98 g/t indium from 351.4 metres depth, including
    • 2.0 metres at 11.8 % zinc, 12.1 % lead, 837 g/t silver & 292 g/t indium from 352.3 metres depth, and
    • 1.4 metres at 29.2 % zinc, 0.4 % lead, 58 g/t silver & 24 g/t indium from 357.0 metres depth, and
    • 4.6 metres at 16.8 % zinc, 0.1 % lead, 15 g/t silver and 26 g/t indium from 361.2 metres depth.

Hole A18-111 (Zone 3):

  • 1.3 metres at 6.5 % zinc & 0.3 % lead from 278.2 metres depth

Hole A18-110 (Zone 3):

  • 3.8 metres at 3.7 % zinc & 0.3 % lead from 278.2 metres depth; and
  • 3.4 metres at 4.8 % zinc & 48 g/t indium from 322.6 metres depth; and
  • 12.1 metres at 4.9 % zinc & 212 g/t indium from 372.7 metres depth.

Note: true thicknesses of the zinc intersections are estimated to be at least 85% of the downhole thicknesses.

Dr. Graham Carman, Tinka´s President and CEO, stated: “We are very pleased to have intersected significant high-grade zinc mineralization in our first step-out hole at West Ayawilca in 2018. It is still early in this year’s drill program, but we are confident that our planned 15,000 metre drill program will continue to expand on our known mineralized zones, discover new areas of zinc mineralization, and add significant new mineral resources to the project. Approximately 25-30 holes are planned for the first half of 2018 consisting mostly of step-out holes, with an initial Preliminary Economic Assessment planned to be completed before year´s end.”

“The new mineralization in A18-114 at West Ayawilca is located on the eastern limb of an ‘anticline’ fold axis which Company geologists believe acted as a trap for the zinc mineralization – refer to cross section provided. With three drill rigs operating at the project from the end of April, we expect plenty of news flow over coming months. Following the recent bought deal financing and the closing of the current private placement, the Company will have raised C$16.2 million thanks to strong support from our existing shareholders, as well as from new shareholders. Tinka is now fully funded to execute its ambitious exploration programs for the next 18 months, which are designed to advance and de-risk the Ayawilca project.”

Note: An “Anticline” is a geological structure whereby the strata are folded into an upside down ‘U’. A “syncline” is the opposite with strata folded in an ‘U’ shape.
Hole A18-112 at Zone 3 did not intersect significant zinc mineralization, while hole A18-113 at Zone 3 has results pending. Drill holes A18-118 (West Ayawilca) and A18-119 (Zone 3) are in progress. Refer to Figure 1 for locations of new holes, and Figures 2 and 3 for interpretative cross sections.

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 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 using multi-acid digestion. Samples assaying over 1% zinc, lead, or copper and over 100 g/t silver are re-assayed using precise ore-grade AAS techniques.

True thicknesses of the zinc intersections are estimated to be at least 85% of the downhole thickness. Significant new drill intercepts are summarized in Table 1 with the strongest intercepts in bold text. Table 2 summarizes the drill collar information for the recent holes.
