Tinka Announces Filing of NI 43-101 Technical Report on the Ayawilca Project, Peru

VANCOUVER, Dec. 18, 2017 /PRNewswire/ - Tinka Resources Limited ("Tinka" or the "Company") (TSXV & BVL: TK) (OTCPK: TKRFF) Vancouver, Canada announces that the Company has filed an independent National Instrument 43-101 Technical Report (the "NI 43-101 Technical Report") on the Mineral Resource Estimate for the Ayawilca Property, Department of Pasco, Peru, in support of the Company's news release dated November 8, 2017.  

The updated Inferred Mineral Resource estimate for the Ayawilca Zinc Zone has more than doubled since May 2016 and is now estimated to be 42.7 million tonnes grading 7.3 % zinc equivalent (ZnEq). In addition, Tinka announced an updated tin-copper-silver resource estimated to be 10.5 million tonnes grading 0.70% tin equivalent (SnEq). The Tin Zone and Zinc Zone resources do not overlap.  Both of the Mineral Resources were assigned to the Inferred category and reported at an NSR cut-off value of US$55/tonne, as estimated by Roscoe Postle Associates Inc. of Toronto, Canada ("RPA Inc.").  

Tinka is continuing to drill beyond the Mineral Resource boundaries looking for new zinc discoveries and/or extensions of known mineralization.  On December 6, 2017, the Company announced a new discovery at Zone 3 with one hole intersecting significant mineralization of 10.3 metres at 5.9 % zinc, 2.0 % lead & 66 g/t silver from 570.2 metres, including 4.5 metres at 9.4 % zinc, 1.1 % lead & 45 g/t silver from 576.0 metres depth (see news releases Dec. 6/17).

Highlights of the Mineral Resource Updates

• Inferred Zinc Mineral Resource of 42.7 million tonnes grading 6.0 % zinc, 0.2 % lead, 17 g/t silver & 79 g/t indium (7.3 % ZnEq), containing:
• 5.6 billion pounds of zinc;
• 3,361 tonnes of indium;
• 23.1 million ounces of silver; and
• 209 million pounds of lead.
• Inferred Tin Mineral Resource of 10.5 million tonnes grading 0.63 % tin, 0.23 % copper, & 12 g/t silver (0.70 % SnEq), including:
• 145 million pounds of tin;
• 53 million pounds of copper; and
• 4.2 million ounces of silver.

The Colquipucro Deposit Indicated Mineral Resource of 7.4 million tonnes grading 60 g/t silver and Inferred Mineral Resource of 8.5 million tonnes grading 48 g/t silver remains unchanged since the February 2015 mineral resource estimate.

Dr. Graham Carman, Tinka's President and CEO, stated: "The NI 43-101 report now filed includes all drill results up to October 10, 2017. Tinka plans to continue drill testing new areas, including Zone 3, with the aim of increasing the resources further.  At the same time, we are de-risking the project with additional metallurgical and desktop mining studies leading to a PEA in 2018."
