PERU – Additional drilling at its 100%-owned Ayawilca project in the zinc-lead-silver belt of central Peru, 200 km northeast of Lima, has significantly grown the project’s resource estimate from a maiden resource estimate in 2015,
Tinka Resources says.
The carbonate replacement deposit at Ayawilca contains two different types of mineralization, tin-copper mineralization (the Tin zone), and zinc-indium-silver-lead mineralization (the Zinc zone). The resources of each zone do not overlap.
The Zinc zone now contains indicated resources of 11.7 million tonnes grading 6.9% zinc, 0.16% lead, 15 g/t silver and 84 g/t indium per tonne. That adds up to 1.8 billion lb. of contained zinc, 42 million lb. of lead, 5.8 million oz. of silver, and 983 tonnes of indium.
The Zinc zone’s inferred resources contribute another 45 million tonnes grading 5.6% zinc, 0.23% lead, 17 g/t silver and 67 g/t indium for 5.6 billion lb. of contained zinc, 230 million lb. of lead, 25.2 million oz. of silver and 3,003 tonnes of indium.
Ayawilca’s Tin zone contains inferred resources of 14.5 million tonnes grading 0.63% tin, 0.21% copper and 18 g/t silver for 201 million lb. of contained tin, 67 million lb. of copper and 8 million oz. of silver.
The drill database includes 71,200 metres in 185 drill holes.
The Ayawilca deposit “represents one of the largest zinc resources held in a non-producing resources company,” while the tin deposit “is believed to be the largest undeveloped tin resource outside of a producing camp in Peru,” the company’s president and CEO, Graham Carman stated in a press release.
Tinka expects to complete a preliminary economic assessment in the first half of next year.
At the end of September, Tinka had $13 million in cash and no debt and says its work programs “are fully funded into the foreseeable future.” This includes additional step-out and deeper exploration drilling planned in 2019.
The project is part of a large zinc sulphide system in central Peru’s zinc-silver belt, and is situated about 40 km northwest of the mining city of Cerro de Pasco.
Cerro de Pasco has a population of about 70,000 people and is situated 4,300 metres above sea level in the Andes. The city is adjacent to a giant open pit mine called Raul Rojas, which is owned by Volcan Compania Minera.
Glencore owns roughly 23% of Volcan.
At press time in Toronto, Tinka was trading at $0.35 per share within a 52-week range of $0.30 and $0.78.
The junior exploration and development company has 265 million common shares outstanding for a market cap of $92.6 million.
