J U N E / J U L Y 2 0 1 8 www.resourceworld.com 11 La Arena consists of the currently operat- ing La Arena Mine and La Arena 11 Project. Although the La Arena Mine and La Arena 11 project are situated on the La Arena property, which is owned by Tahoe, they are stand-alone projects and independent of each other. La Arena 11 would not be an expansion of the current operation; rather, it would be a separate operation constructed at the end of the La Arena Mine life. The company recently released results of a Preliminary Economic Assessment for La Arena 11, a copper-gold porphyry proj - ect. The PEA foresees a 21-year mine life. Average annual production is estimated at 149,000 oz of gold and 207 million pounds of copper, plus an additional 226,000 oz of gold and 115 million pounds of copper recovered over a two-year period. Capital cost is estimated at $1.36 billion for ini - tial project capital (net of pre-production operating credit) and $1.09 billion for sus- taining capital over the life of the mine. Tinka Resources Ltd. [TK-TSXV] is a mineral exploration and development company focused on expanding and de-risking the high-grade resource at its 100%-owned Ayawilca property, one of the largest zinc discoveries made in Peru during the past 20 years. Inferred resources as of November 2017 stood at 42.7 million tonnes at 7.3% zinc equiva - lent (6.0% zinc, 0.2% lead, 17 g/t silver and 79 g/t indium, and 10.5 million tonnes grading 0.70% tin equivalent. Metallurgical testing is ongoing and engineering studies were scheduled to commence in early 2018, kick-starting a preliminary economic assessment of the currently known mineral resources. Trevali Mining Corp. [TV-TSX, Lima; TREVF-OTCQX, 4T1-FSE] is a zinc-focused base metals company with four mines. They are the 100%-owned Santander Mine in Peru, the wholly-owned Caribou Mine in Bathurst, New Brunswick, the 80%-owned Rosh Pinah Mine in Namibia and the 90%-owned Perkoa Mine in Burkina Faso. Santander (Magistral) reserves at the end of 2017 stood at 1.93 million tonnes of proven and probable grading 4.38% zinc, 0.75% lead and 30.79 g/t silver. At Santander, Trevali continues to chase Magistral at depth; however, it is now looking for potential higher-grade skarn mineralization as part of its regional initiative. Zinc One Resources Inc. [Z-TSXV; ZZZOF-OTC] has released additional drill results from the Mina Grande Sur Zone at its 100%-optioned Bongara zinc mine project located in north-central Peru. To date, 81 drill holes for 1,810.6 metres have been drilled, from which assays have been received for 24 holes. Significant new intercepts include: hole MGS18016 with 4.7 metres of 26.1% zinc from surface and hole MGS18017 with 8.2 metres of 42.7% zinc from a 7.5-metres drill depth. Earlier drill hole MCH18013 returned 19.8 metres of 46.8% from a 1.9-metre drill depth. n PERU
