Tinka Resources' testwork shows high zinc recoveries achievable at Ayawilca with standard processing

The samples were from mineralization at west and south Ayawilca zones at the project, which lies 200km from Lima

Metallurgical testing on Tinka Resources Ltd's (CVE:TK) (OTCPK:TKRFF) samples from its Ayawilca zinc project in Peru show high recoveries can be achieved with a standard flotation process, the firm told investors Wednesday.

The samples were from mineralization at west and south Ayawilca zones at the project, which lies in the zinc-lead-silver belt 200 kilometres northeast of Lima.

The testing showed recoveries of 92% zinc at a concentrate grade of 50% could be consistently achieved using a standard flotation process.

Two tests were carried out on two different styles of mineralization and both produced similar concentrates, the resource group said.

"We are very pleased with the results of the metallurgical testwork, which has been completed to a high standard, as it predicts very high zinc recoveries from the mineralization at Ayawilca, said CEO Graham Carman.

"We believe the Ayawilca zinc concentrate will be desirable for many smelters due to the low levels of silica, manganese and other deleterious elements, as well as for the high indium levels."

Completing the PEA

Carman added that the group was looking forward to completing its PEA (preliminary economic assessment) before the end of June this year. 

"As the project progresses, we will continue to seek improvements in the zinc and lead metallurgy with additional testwork," he said.

The Ayawilca zinc zone contains 11.7 Mt (million tonnes) of indicated resources grading 6.9% zinc, 0.2% lead, 15 g/t silver and 84 g/t indium.

There are 45 Mt of lower confidence inferred resources grading 5.6% zinc, 0.2% lead, 17 g/t silver and 67 g/t indium. 

Meanwhile, the tin zone contains an inferred resource of 14.5 Mt at 0.63% tin, 0.21% copper an 18 g/t silver.

Tinka shares in Toronto added around 3.2% to $0.32 each.
