Tinka Resources (TSXV: TK) has doubled the resource at its 100% owned Ayawilca polymetallic sulphide project, located 200 km northeast of Lima in Peru’s Department of Pasco.
The four zinc zones and one tin zone are located on the larger Ayawilca property at altitudes between 3,800 and 4,300 metres, with the zinc resource open in several directions. In the report, Tinka uses a US$55 per tonne net smelter return cut-off rate for both the zinc zones and the tin zone.
The new estimate includes an additional 15,000 metres drilled in 2017. Tinka now estimates the zinc resource at Ayawilca contains 42.7 million inferred tonnes grading 6.0 % zinc and 0.2 % lead with 17 grams silver per tonne and 79 grams indium per tonne. Its previous estimate pegged the resource at 18.8 million inferred tonnes grading 5.9 % zinc and 0.2 % lead with 15 grams silver per tonne and 74 grams indium per tonne.
