Vancouver, Canada – Tinka Resources Limited (“Tinka” or the “Company”) (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to announce partial results from drill hole A20-170 and full results from A20-169, the first two holes of the 2020 drill program at the Ayawilca project in central Peru. Drill hole A20-170 at South Ayawilca intersected several zones of high-grade zinc (silver-lead) mineralization from 203 metres to 357 metres depth, with assay results reported here to a depth of 309 metres only. Assay results for mineralized samples beyond 309 metres depth are pending. The receipt of assays from the laboratory has been slower this year due to the impacts of COVID-19 in Peru.
Hole A20-170 (South Ayawilca)
- 12.2 metres @ 4.1% zinc, 1.2% lead & 60 g/t silver from 202.9 metres depth, including
- 2.2 metres @ 10.2% zinc, 2.5% lead & 121 g/t silver from 202.9 metres depth; and
- 3.7 metres @ 6.5% zinc, 0.1% lead & 13 g/t silver from 243.2 metres depth; and
- 25.9 metres @ 10.0 % zinc & 15 g/t silver from 282.6 metres to end of sampled interval, including
- 13.7 metres @ 15.9% zinc & 26 g/t silver from 282.6 metres depth;
- These are partial results only – significant visible zinc and iron sulphide mineralization has been observed from 309 metres depth (end of reported interval above) to the contact with the underlying phyllite at 357 metres depth – assay results for this interval are pending;
- Mineralization is associated with gently dipping sulphide rich “mantos” hosted by limestones;
- True thicknesses of the manto intersections are estimated to be at least 90% of the downhole thicknesses.
Hole A20-169 (West Ayawilca)
- 0.9 metres @ 13.7% zinc, 0.6% lead & 133 g/t silver from 108.8 metres depth; and
- 1.1 metres @ 12.4% zinc, 2.1% lead & 147 g/t silver from 136.0 metres depth; and
- 1.1 metres @ 18.8% zinc, 5.0% lead & 172 g/t silver from 190.0 metres depth; and
- 0.7 metres @ 15.2% zinc, 1.3% lead & 71 g/t silver from 210.5 metres depth; and
- 1.2 metres @ 22.7% zinc, 3.9% lead & 190 g/t silver from 356.8 metres depth.
- Mineralization in hole A20-169 is vein style – these veins have unknown true thicknesses.
Hole A20-170 is an infill hole within the overall footprint of the inferred resource at South Ayawilca. Hole A20-169 is a step-out hole 75 metres west of the existing inferred resource at West Ayawilca – this hole intersected several high-grade but narrow zinc-silver-lead veins. So far in the drill program, approximately 2,500 metres have been completed in seven drill holes (see Figure 1 for a map of drill holes). The overall program is now expected to extend into early 2021. Several drill targets still remain to be tested, including the large area between West and South Ayawilca which has seen limited past drilling.
President and CEO of Tinka, Dr. Graham Carman, stated: “These initial drill results are a great start to the 2020 drill program. Hole A20-170 intersected a better than expected zone of high grade zinc mineralization at South Ayawilca, with additional mineralization to be reported from deeper in the hole once results are received from the lab. Importantly, this hole hit high grade silver-zinc-lead mineralization as well as massive pyrrhotite at shallower than usual depths, suggesting that replacement of limestone by sulphides is much thicker in this area than previously recognised. Additional holes are planned to further drill test this high grade area, as well as the large gap between West and South.”
About Ayawilca: The Ayawilca Zinc Zone (sulphide) 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 (oxide) contains an estimated 14.3 million ounces silver in the Indicated category and 13.2 million ounces silver in the Inferred category, with mineralization starting from surface (see link to 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.
