Tinka Resources has revealed analytical results from A13-14 to A13-17 holes at its Ayawilca project in west-central Peru.

At A13-15 hole is located on section 333300E, 100m west of the highly significant intercept found in hole A12-08. It intersected massive and semi-massive sulphides between 321.1m and 344.4m depth with locally moderate concentrations of sphalerite in a matrix dominated by pyrite and pyrrhotite.

In hole A13-16, semi-massive sulphides were intersected between 354.9m and 359.1m and consisted of sphalerite and pyrite.

"Although the drill sections are spaced widely apart, mineralisation has now been traced for 1,000m between the site of holes A13-05, A13-06 to the west and holes A13-16, A13-17 to the east."

In hole A13-17, semi-massive sulphides (pyrite and sphalerite), along with moderate chlorite and magnetite alteration, occur between depths of 329.6m and 352.6m.

Sphalerite and some galena, were found between 373.1m and 378.9m with the same style of alteration. Massive pyrrhotite, containing pyrite, sphalerite and lesser chalcopyrite, occurs from 380.1m and 405.6m depth.

"Drilling is currently underway 130m to the north of these holes."

The company performed all diamond drilling using HQ diameter drill rods. It said that the geometry of and controls to the mineralisation are not yet fully understood.
