The Ayawilca Property is located 200 km northeast of Lima in the Department of Pasco, Central Peru, at altitudes of between 3,800 and 4,300 metres. The Property is 40 km northwest of the world-class Cerro de Pasco zinc-lead-silver mine, and 100 km south of the giant copper-zinc Antamina mine. Tinka owns 100% of the contiguous 150 km2 mining concessions at Ayawilca.

Tinka is focusing on growing the Ayawilca Zinc Mineral Resource as its number one priority at the Property. The new 2017+ drill permit covers three times the area of the previous (2013-2015) drill permit, including many previously undrilled targets and potential resource extensions. The Company expects to be drill testing at Ayawilca throughout much of 2017, with a 10,000 metre drill program commencing in early 2017.

Three NI 43-101 Mineral Resources exist on the Property, and were defined by Tinka:

The Zinc Zone has an Inferred Mineral Resource (May 25 2016) of 18.8 million tonnes at 8.2 % Zinc Equivalent (5.9 % zinc, 74 g/t indium, 15 g/t silver, 0.2 % lead) containing 2.4 billion pounds of zinc, 1,385 tonnes of indium, 8.8 million ounces of silver, and 82 million pounds of lead. Zinc mineralization is open in most directions.

The Tin Zone has an Inferred Mineral Resource (May 25 2016) of 5.4 million tonnes at 0.89 % Tin Equivalent (0.76 % tin, 0.31 % copper, 18 g/t silver) containing 90 million pounds of tin, 37 million pounds of copper, and 3.1 million ounces of silver. Mineralization is open in most directions.

The Colquipucro Silver Zone has a Mineral Resource (February 26 2015) of 7.4 Mt at 60 g/t silver for 14.3 Moz silver (Indicated) and 8.5 Mt at 48 g/t silver for 13.2 Moz silver (Inferred) in a preliminary open pit shell generated in Whittle software. Colquipucro is located 2 km north of Ayawilca, with mineralization occuring from surface to a depth of 80 metres. It has the potential to be a starter pit with a very low strip. Silver mineralization is oxidized, and remains open to the northeast.
