Key highlights
Drill holes A22-200, A22-197 and A22-198 all intersected high-grade zinc mineralization at West Ayawilca:
A22-200: 44.9 metres at 12.0% zinc from 283.3 metres depth, including 16.1 metres at 22.2% zinc from 312.1 metres depth.
A22-197: 79.4 metres at 5.3% zinc from 271.6 metres depth, including 26.3 metres at 8.4% zinc from 281.7 metres depth.
A22-198: 37.0 metres at 5.2% zinc from 312.3 metres depth, including 7.2 metres at 9.1% zinc from 326.0 metres depth.
Drill hole A22-193 intersected high-grade silver mineralization at relatively shallow depth on the edges of the zinc zone mineralization at West Ayawilca:
A22-193: 21.6 metres at 175 g/t silver, 1.0% zinc and 0.3% lead from 168.3 metres depth, including 5.8 metres at 567 g/t silver, 0.8% zinc and 0.3% lead from 168.3 metres depth.
Holes reported here were drilled within the existing resource boundaries and will improve the geological knowledge and confidence of the West Ayawilca zinc zone, in particular the distribution of the high-grade zinc sulphide mineralization.
Zinc mineralization remains open at depth beneath hole A22-200.
Drilling is expected to continue into early 2023 with two rigs operating - one at South and one at West.
Results are now reported for nine drill holes in the 2022 drill program, with approximately 12 additional holes planned or in progress with two drill rigs in operation.
True thicknesses of the mineralized intercepts are estimated to be at least 80% of the downhole thicknesses.

Discussion of 2022 drill program results
Tinka has drilled approximately 4,900 metres so far in the 2022 zinc resource definition and expansion program, about halfway through the planned drill program, with several holes pending results and two holes currently in progress (see Figure 1; Table 2). The main objectives of the 2022 drill program at Ayawilca are to target high-grade zinc mineralization and to expand the measured and indicated zinc mineral resources. Indicated resources are currently estimated at 19.0 Mt grading 7.2% Zn, 17 g/t Ag & 0.2% Pb and inferred resources are 47.9 Mt @ 5.4% Zn, 20 g/t Ag & 0.4% Pb (dated
As outlined in this news release, four holes were drilled to test the geometry of the mineralization at West Ayawilca and better define the upper and lower contacts of the massive sulphide zones. The four holes are located on three different east-to-west cross sections approximately 100 metres apart through West Ayawilca (see Figure 1).
Hole A22-193 was drilled to the east to test the extension of the West zinc zone mineralization. A zone of high-grade silver, associated with disseminated pyrite and base metal mineralization, was found at a relatively shallow depth, yielding 5.75 metres grading 567 g/t silver, 0.17 g/t gold and 1% zinc+lead from 168.25 metres. Only minor zinc was intersected; however, a narrow zone of tin mineralization was intersected near the base of the hole (Figure 2A).
Hole A22-197 was drilled to the west on the same section as A22-193, to test the continuity of zinc mineralization previously encountered in holes A14-22 (33 metres at 7.4% Zn & 31 metres at 6.3% Zn) and A18-141 (89.0 metres at 5.0% Zn). A22-197 drilled an intersection of 79.4 metres at 5.3% zinc, including a high-grade interval of 26.3 metres at 8.4% zinc associated with sulphide replacement of limestone breccia. A follow-up hole is currently in progress (see cross section, Figure 2A).
Hole A22-198 was angled to the west on a section 100 metres north of A22-197 (see Figure 1). This hole intersected 37.0 metres at 5.2% zinc within a banded limestone unit associated with magnetite alteration.
Hole A22-200 was drilled a further 100 m to the north, to test the continuity of zinc mineralization in A18-118 (32 metres at 9.6% Zn) and A20-179 (32 metres at 6.0% Zn). A22-200 intersected one of the best zinc zone intervals ever drilled at West Ayawilca - 44.9 metres at 12.0% zinc - proving the continuity of the high-grade massive sulphide zinc mineralization within the lower banded limestone. A follow-up hole is planned (see cross section, Figure 2B).
