VANCOUVER, BC / ACCESSWIRE / January 28, 2021 / Tinka Resources Limited ("Tinka" or the "Company") (TSXV:TK)(BVL:TK)(OTC PINK:TKRFF) is pleased to announce assay results for seven drill holes from the ongoing resource expansion and infill drill program at the Ayawilca project in Peru. Hole A20-177 intersected very high grade vein-style zinc-silver-lead mineralization outside of the zinc resource at about 100 metres depth. Three holes (A20-178, 177 & 175) also successfully intersected high grade manto-style zinc mineralization at the Camp area. Hole A20-179 was an infill hole at the West area which intersected two wide zones of mineralization with better than expected zinc grades. The other three holes intersected extensions of zinc-rich mineralization at the South area (holes A20-176, 174, 172). Tinka has now completed 6,500 metres of the planned 7,500 metres in the resource drilling program. Sixteen holes have been completed with two in progress (A21-185 & 186) and at least two more are planned before the end of the program. Results are now reported for half of the drill holes in the current program.

Mineralization is mostly associated with gently-dipping sulphide "mantos" hosted in limestones.True thicknesses of the mantos are estimated to be at least 90% of the downhole thicknesses. The intervals marked * are vein-style hosted by sandstones and have an unknown true thickness. Refer to map and cross sections in Figures 1 and 2.
President and CEO of Tinka, Dr. Graham Carman, stated: "The 2020-21 Ayawilca drill program continues to deliver high-grade zinc mineralization with significant silver credits. We are particularly excited about the very high-grade zinc-silver vein intersection in hole A20-177, one of the best grade intersections we have ever had at Ayawilca and especially attractive as it occurs at shallow depth. The vein-style mineralization was intersected at a low-angle to the drill core axis so the true width of the vein is currently unknown. The thick vein is hosted in the quartz sandstone member of the Goyllar Formation which was not previously considered as a favourable host rock. The shallow nature of the mineralization (about 100 m depth) opens up the possibility for high-grade zinc-silver-lead resources much closer to surface than previously thought. We plan to follow up this vein with more drilling before the end of the current program to better define its geometry and extent."
"Drill holes at the Camp area have also discovered strong manto-style zinc mineralization outside of the current resource hosted within the limestones. Drilling is continuing currently at the South area with two rigs operating. We expect the program to be completed in February, after which time the data will be compiled for a resource and PEA update. We continue to believe that Ayawilca is perfectly positioned to take advantage of the current positive market sentiment towards base metals, and we look forward with anticipation to the results for the final half of the drill program."
About Ayawilca: The Ayawilca Zinc Zone contains an estimated 1.8 billion pounds zinc and 5.8 million ounces silver in the Indicated category, and 5.6 billion pounds zinc and 25.2 million ounces silver in the Inferred category (see news release dated November 26, 2018). The Colqui Silver Zone contains an estimated 14.3 million ounces silver in the Indicated category and 13.2 million ounces silver in the Inferred category (see Technical Report dated July 2, 2019).

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 ALS laboratories in Lima for assay in batches. Standards and blanks are inserted by Tinka into each batch prior to departure from the 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.
