Tinka “very pleased” with Ayawilca tests

(Before It's News)

Tinka Resources Ltd (CVE:TK) has been heartened by analysis of initial metallurgical flotation tests of zinc sulphide samples from its Ayawilca project, Peru.

The test work proves the zinc sulphide mineralization from West Ayawilca is amenable to industry standard flotation processing, the company said.

Zinc (Zn) recoveries of 98% were produced in first pass, or rougher, flotation tests from two typical grade composites.

A zinc concentrate grade of 52% Zn was achieved in second pass, or cleaner, flotation.

Indium recoveries were similar to the zinc, Tinka revealed.

Shares shot up 14.3% to C$0.20 on the news.

“Initial bench scale metallurgical tests of Ayawilca zinc mineralization have produced excellent first pass zinc recoveries and a market-ready concentrate, important steps towards de-risking the project,” said Dr Graham Carman, president and chief executive officer of Tinka.

“The tests were carried out on typical-grade zinc mineralization from West Ayawilca. Importantly, indium follows the zinc into the zinc concentrate, where we believe it will be payable,” he continued, adding that the company was very pleased with the metallurgical tests.

The results pave the way for the junior exploration company to commence its 2016-2017 resource expansion/drill program with a high degree of confidence that Ayawilca is, in Dr Carman’s words, “one of the most significant zinc exploration-development projects not only in Peru but internationally.”

Ayawilca is located in the highly mineralized zinc-lead-silver belt of central Peru, some 200 kilometres north of Lima and 40 kilometres from Peru’s largest historic zinc mine at Cerro de Pasco.

Ayawilca has two separate inferred mineral resource zones of 18.8mln tonnes (Mt) at 8.2% zinc equivalent, and 5.4 Mt at 0.89% tin equivalent, both open for expansion.
