The work is aimed at converting inferred resources into higher confidence indicated ounces and also to test for extensions of zinc and silver mineralization down-dip of known zones of mineralization in step-out holes.
Two drill rigs are currently on site, with a third expected to be added by the end of October.

"It is exactly 12 months since Tinka was last drilling at Ayawilca, and our team is very excited to be back drilling again after what has proven to be a challenging year due to the severe impact of the pandemic in Peru," noted chief executive Dr Graham Carman in a statement.
"We are targeting two styles of mineralization; zinc-rich massive sulphide mineralization typical of the Ayawilca Zinc Zone, and silver-rich mineralization which occurs in carbonate veins and replacements on the margins of the sulphide deposit.
"We expect to release the drill results as soon as they become available and can be interpreted within the context of our geological model. Tinka has put in place enhanced health protocols to keep our employees, contractors and community workers as safe as possible."
Later in the program, step-out holes will test new exploration targets at the Colqui silver zone, Tinka added.
The Ayawilca sulphide zinc zone contains an estimated 1.8 billion pounds zinc and 5.8 million ounces silver in the indicated category, and 5.6 billion pounds zinc and 25.2 million ounces silver in the inferred category.
The Colqui silver zone (oxide) contains an estimated 14.3 million ounces silver in the indicated category and 13.2 million ounces silver in inferred category, with mineralization starting from surface.
