Tinka Resources Ltd. has provided an updated mineral resource estimate for its 100-per-cent-owned Ayawilca zinc and tin deposits in Peru. Part of the zinc zone mineral resource is now classified as indicated, incorporating a higher-grade portion of the deposit. In addition, the updated inferred mineral resource is of a similar size and grade to the previous zinc zone resource reported in November, 2017. The updated tin zone inferred mineral resource is also substantially larger. This resources update follows a very successful drilling program, with the company completing approximately 20,000 metres during 2018.
Key highlights of updated mineral resources at Ayawilca
- Indicated zinc zone mineral resource of 11.7 million tonnes grading 6.9 per cent zinc, 0.16 per cent lead, 84 grams per tonne (g/t) indium and 15 g/t silver (8.1 per cent zinc equivalent (ZnEq)), containing:
- 1.8 billion pounds of zinc;
- 983 tonnes of indium;
- 5.8 million ounces of silver;
- 42 million pounds of lead.
- Inferred zinc zone mineral resource of 45.0 million tonnes grading 5.6 per cent zinc, 0.23 per cent lead, 67 g/t indium and 17 g/t silver (6.7 per cent ZnEq), containing:
