Tinka Resources update on Ayawilca project

Tinka Resources Limited announced that assay results for seven recent holes from its ongoing resource step-out drill program at the Company's 100%-owned Ayawilca project, central Peru. Six holes are reported from the West Ayawilca area (holes A18-117, 120 to 122, 126, 129) and one from the Central area (A18-127).

Hole A18-129 has intersected exceptional grades of zinc sulphide mineralization at West Ayawilca in a new setting for mineralization at Ayawilca. A mineralized interval of 10.4 metres grading 44.0% zinc occurs within a zone consisting of more than 90% zinc sulphides. This is the highest-grade zinc intersection ever encountered at Ayawilca over a significant interval. The high-grade mineralization occurs immediately beneath phyllite within a repetition of the Pucara limestone formation which is favourable for mineralization and typically found above the phyllite. The mineralized interval is interpreted to be flat-dipping and close to true thickness. This is the first time that Tinka has tested the proposition that there may be a repetition of the mineralized Pucara limestone under the phyllite encountered at the base of most other holes at Ayawilca. It is notable that such an outstanding zinc intercept has been drilled in the first repetition of the Pucara limestone encountered thus far. Additional drill holes are planned to test for the continuation of the high grade mineralization in this repeated limestone.

The new discovery opens up significant areas of untested potential, both beneath and adjacent to the existing mineral resource. Most of the previous drill holes at Ayawilca were stopped a few metres into the phyllite, which had been considered to be 'basement'. A new interpretation of the geology at West Ayawilca indicated that the favourable limestone unit could be repeated under low angle 'thrust' faults, a concept that is now corroborated.

Three drill rigs continue to operate at the project 24/7 in the resource expansion program. Two rigs are drilling deep holes at West Ayawilca, while the third rig is at South Ayawilca testing for repetitions of the mineralization beneath the South Ayawilca resource.
