Tinka Drills 45 Metres @ 12% Zinc Including 16 Metres @ 22% Zinc at West Ayawilca

Tinka Resources Limited ("Tinka" or the "Company") (TSXV & BVL: TK) (OTCQB: TKRFF) is pleased to announce results from four recent drill holes from the Company's ongoing infill and resource expansion drill program at the Ayawilca zinc project in Peru. Drill holes reported (A22-193, 197, 198 and 200) are from the West Ayawilca area and all have intersected high-grade mineralization. A particular highlight is the high-grade zinc intercept in hole A22-200, one of the best drill hole intersections ever made at West Ayawilca, with 44.9 metres at 12.0% zinc including 16.1 metres at 22.2% zinc. Results have now been reported for nine holes in the current program (including four in this release), with five more drill holes pending (including holes A22-202 and A22-203, which are in progress). A second drill rig has been mobilized and two rigs are operating 24-7, one located each at West and South Ayawilca

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.

Dr. Graham Carman, Tinka's President and CEO, stated: "The interval of 16 metres grading 22% zinc in hole A22-200 is one of the best zinc intersections ever drilled at West Ayawilca. All of the new drill holes have confirmed that the zinc sulphide mineralization at West occurs as strata-bound sulphide replacement of the lowermost limestone and breccia-filling sulphide replacement of the overlying carbonate rocks. Several more holes are planned to follow-up on these great drill results, targeting the highest-grade parts of the zinc deposit and possible extensions. The drill program at Ayawilca is continuing with two rigs - one targeting West and the other South Ayawilca (where several holes have results pending). We expect to be reporting drill results for several more months, with a resource update expected Q1 2023."

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 August 30^th, 2021). Figure 1 shows a location map of the 2022 drill holes at the Ayawilca project.

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).

Notes on sampling and assaying

Drill holes are diamond HQ size core holes with recoveries generally above 80% and often close to 100%. The drill core is marked up, logged, and photographed on site. The cores are cut in half at the Company's core storage facility, with half-cores stored as a future reference. Half-core was bagged on average over 1 to 2 metre composite intervals and sent to ALS and SGS laboratories in Lima for assay in batches. Standards and blanks were inserted by Tinka into each batch prior to departure from the core storage facilities. At the laboratory samples are dried, crushed to 100% passing 2mm, then 500 grams pulverized for multi-element analysis by ICPMS using multi-acid digestion. Samples assaying over 1% zinc, lead, or copper and over 100 g/t silver were re-assayed using precise ore-grade AAS techniques. Samples within massive sulphide zones were also assayed for tin using XRF techniques.
