Vancouver’s Tinka Resources has released positive news from the last round of assay results from their Ayawilca project in Peru.
Highlight figures include results from hole A19-165 where four separate, gently dipping mineralized zones with downhole thicknesses of between 9 and 29 metres and grading between 11.8% and 14.0% zinc, within a cumulative downhole interval of 170 metres (note: downhole thicknesses approximate true thicknesses in this hole).
Hole A19-167, intersected very high grade silver mineralization (>1,000 g/t Ag) accompanied by base metals (14.5% Zn, 0.3% Pb) over a narrow 1.7 metre interval approximately 100 metres beneath the existing Zinc Zone resource, within a wider zone of lower grade silver mineralization associated with strongly altered Pucará limeston. The silver intersection in hole A19-167 lies 80 metres from the silver intersection in hole A19-163 (13.9 metres at 130 g/t Ag. This new “Silver Zone” discovery supports Tinka´s view that Ayawilca still has significant exploration potential, including upside for precious metals.
Tinka’s President and CEO, Dr. Graham Carman, stated that the results had confirmed continuity of mineralization and had increased their confidence in the geological model they have developed. “Zinc grades in the upper two zones were higher than predicted by the resource model. Multiple phases of zinc mineralization, as indicated by spectacular colour banding of the sphalerite crystals, indicate that the mineralization at Ayawilca was multi-phase while also highlighting the fact that each phase added to the zinc grade of the deposit.”
Commenting on the silver mineralization found in hole A19-167, Dr Carman stated: “The success of A19-167 proves that Ayawilca has very high -grade silver mineralization which is believed to have developed around the edge of the Ayawilca Zinc Zone.This recent discovery offers a new exploration target and potentially significant precious metal upside to supplement the very large zinc resource.”

• 25.9 metres @ 11.8% zinc, 0.2% lead, 23 g/t silver & 325 g/t indium from 167.8 metres, including
• 4.0 metres @ 24.6% zinc, 33 g/t silver, 0.1% lead & 475 g/t indium from 169.1 metres;
• 7.0 metres @ 18.9% zinc, 42 g/t silver, 0.5% lead & 584 g/t indium from 178.4 metres; and
• 28.7 metres @ 14.0 % zinc, 14 g/t silver, 0.1% lead & 101 g/t indium from 214.6 metres, including
• 18.65 metres @ 17.4% zinc, 11 g/t silver, & 68 g/t indium from 221.5 metres; and
• 14.9 metres @ 12.3% zinc, 38 g/t silver, 0.6% lead & 297 g/t indium from 271.5 metres, including
• 1.2 metres @ 36.6% zinc, 80 g/t silver, 0.2% lead & 1020 g/t indium from 278.6 metres;
• 0.95 metres @ 44.1% zinc, 90 g/t silver, 0.3% lead & 867 g/t indium from 285.45 metres.
• 0.8 metres @ 38.5% zinc, 117 g/t silver & 0.4% lead & 442 g/t indium from 122.3 metres; and
• 0.85 metres @ 31.1% zinc, 40 g/t silver & 311 g/t indium from 138.7 metres.
Hole A19-167(extension of drill hole A17-064 from 361 metres depth)
• 7.3 metres @ 4.9% zinc, 366 g/t silver & 0.5% lead from 412.7 metres, including
• *1.7 metres @ 14.5% zinc, 1,130 g/t silver & 0.3% lead from 412.7 metres; and
• 7.85 metres @ 6.1% zinc, 150 g/t silver & 0.8% lead from 434.45 metres, including
• 0.9 metres @ 21.7% zinc, 415 g/t silver & 3.0% lead from 434.5 metres.
Note: True thicknesses of the Zinc Zone intersections are estimated to be approximately equal to the downhole thicknesses in hole A19-165 and at least 85% of the downhole thicknesses in A19-166. The true thickness of the Silver Zone intersections in A19-167 cannot be determined at this time as insufficient data is available.
