Tinka Reports High Zinc Recoveries In Metallurgical Tests From Ayawilca

June 5th, 2019

Vancouver, Canada – Tinka Resources Limited (“Tinka” or the “Company”) (TSXV & BVL: TK) (OTCPK: TKRFF) is pleased to announce the results of metallurgical testwork on composite zinc sulfide samples from the Company’s 100%-owned Ayawilca property in central Peru.The metallurgical test program was carried out by XPS Consulting and Testwork Services, Ontario, under the coordination of Adam Johnston of Transmin Metallurgical Consultants.

Key Highlights

The objective of the testwork was to develop a flowsheet using standard flotation for the zinc mineralization at West and South Ayawilca, which was successfully achieved.
Testwork results have demonstrated that recoveries of 92% zinc at a concentrate grade of 50% zinc can be consistently achieved using a standard flotation process. Two locked cycle tests were carried out on two different styles of mineralization and both tests produced similar zinc concentrates.
Potentially deleterious elements in the zinc concentrates (including silica, manganese, cadmium, mercury, and arsenic) were well below standard smelter penalty levels.A small penalty is anticipated for iron content in the concentrate.
Indium in the two locked cycle zinc concentrates (719 ppm and 400 ppm, respectively) is very high and potentially payable, subject to the smelter and commercial arrangements.
Details of the processing flowsheet for zinc and lead concentrates will be incorporated into the upcoming Preliminary Economic Assessment (“PEA”).The Company expects to release the results of the PEA for the Ayawilca zinc project before the end of June 2019.
