Tinka announces new discovery at Zone 3, drills 10 metres grading 7.9 % zinc+lead

VANCOUVER, Dec. 6, 2017 /PRNewswire/ - Tinka Resources Limited ("Tinka" or the "Company") (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to announce results for six new drill holes at the Company's 100%-owned Ayawilca project in central Peru. Three holes are resource step-out holes at South Ayawilca, two holes are resource infill holes, and one hole intersected significant mineralization at the "Zone 3" area for the first time. Drill hole A17-091A (previously A17-091, which was deepened from 480 metres to 625 metres depth) encountered massive sulphide replacements of the carbonate host rocks from 569 to 594 metres depth. An upper 10 metre interval intersected pyrite with significant zinc-lead-silver mineralization, while the lowermost 14 metre interval intersected significant tin-copper-silver mineralization with massive pyrite. In addition, drill hole A17-100 has extended the known South Ayawilca zinc mineralization by about 200 metres eastward, with mineralization still open (Figure 1). 

Key Highlights
Hole A17-091A (Zone 3 ? New Discovery):

• 10.3 metres at 5.9 % zinc, 2.0 % lead & 66 g/t silver from 570.2 metres (* MS), including
• 4.5 metres at 9.4 % zinc, 1.1 % lead & 45 g/t silver from 576.0 metres depth; and
• 13.5 metres at 0.83 % tin, 0.39 % copper & 54 g/t silver from 588.50 metres depth (* MS), including
• 7.5 metres at 1.14 % tin, 0.14 % copper & 54 g/t silver from 588.5 metres depth; and
• 4.0 metres at 1.04 % tin, 0.11 % copper & 5 g/t silver from 608.0 metres (veins in phyllite), including
• 2.0 metres at 1.82 % tin, 0.13 % copper & 6 g/t silver from 610.0 metres depth.

Hole A17-100 (South Ayawilca ? 200 metre step-out)

• 3.0 metres at 9.1 % zinc, 0.2 % lead & 79 g/t silver from 225.5 metres depth.

Hole A17-101 (South Ayawilca ? infill)

• 7.2 metres at 6.5 % zinc, 136 g/t indium and 10 g/t silver from 350.8 metres depth, including
• 2.0 metres at 14.7 % zinc, 324 g/t indium & 15 g/t silver from 356.0 metres depth.

Hole A17-102 (South Ayawilca ? infill):

• 4.0 metres at 7.1 % zinc & 52 g/t silver from 356.5 metres depth.

Dr. Graham Carman, Tinka´s President and CEO, stated: "We believe the new intercepts in drill hole A17-091A are very significant, as they open up the Zone 3 area for potential resource expansion in an area that has seen little drilling. The same magnetic anomaly that outlines the Ayawilca Zinc and Tin Zones continues into Zone 3, extending the prospective zone by hundreds of metres to the northeast. A drill rig will continue to operate in the Zone 3 area following-up on this exciting discovery.  Drilling is now expected to continue well into 2018 without a break, other than for the Christmas period."

Dr. Carman continued: "These holes are the first to be released following our zinc and tin resource update (see Press Release Nov 8, 2017). Already, new results are indicating that the project is likely to continue to grow with additional drilling. Drill hole A17-100 intersected 3 metres grading 9.1 % zinc in a 200-metre step-out hole from the resource at South Ayawilca. A large 750-metre gap remains undrilled between significant zinc intersections at South Ayawilca and Zone 3. While exploration drilling continues with the goal of expanding the project resources, we are concurrently working on de-risking the project through metallurgical tests of the two main styles of mineralization as well as beginning preliminary desktop mining studies. We look forward to providing updates on these programs as they progress." 

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

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.

Samples which assay approximately 200 ppm tin or greater in the ICP analysis are re-assayed for tin by fusion with sodium peroxide and AAS finish (SGS Lima laboratory method SGS-AAS90B).
