Prolific, Underexplored, District-scale Asset with First Nations Partnership

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, together with 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, together with 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, together with 7.2 metres at 9.1% zinc from 326.0 metres depth.
• Drill gap A22-193 intersected high-grade silver mineralization at comparatively shallow depth on the perimeters 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, together with 5.8 metres at 567 g/t silver, 0.8% zinc and 0.3% lead from 168.3 metres depth.
• Holes reported right here have been drilled inside the present useful resource boundaries and can enhance the geological information and confidence of the West Ayawilca zinc zone, specifically the distribution of the high-grade zinc sulphide mineralization.
• Zinc mineralization stays open at depth beneath gap A22-200.
• Drilling is anticipated to proceed into early 2023 with two rigs working – one at South and one at West.
• Outcomes are actually reported for 9 drill holes within the 2022 drill program, with roughly 12 further holes deliberate or in progress with two drill rigs in operation.

True thicknesses of the mineralized intercepts are estimated to be no less than 80% of the downhole thicknesses.

Dr. Graham Carman, Tinka’s President and CEO, acknowledged: “The interval of 16 metres grading 22% zinc in gap A22-200 is without doubt one of the greatest zinc intersections ever drilled at West Ayawilca. All the new drill holes have confirmed that the zinc sulphide mineralization at West happens as strata-bound sulphide substitute of the lowermost limestone and breccia-filling sulphide substitute of the overlying carbonate rocks. A number of extra holes are deliberate to follow-up on these nice drill outcomes, focusing on the highest-grade elements of the zinc deposit and attainable extensions. The drill program at Ayawilca is continuous with two rigs – one focusing on West and the opposite South Ayawilca (the place a number of holes have outcomes pending). We anticipate to be reporting drill outcomes for a number of extra months, with a useful resource replace anticipated Q1 2023.”

Dialogue of 2022 drill program outcomes

Tinka has drilled roughly 4,900 metres to date within the 2022 zinc useful resource definition and growth program, about midway by way of the deliberate drill program, with a number of holes pending outcomes and two holes at present in progress (see Determine 1; Desk 2). The primary aims of the 2022 drill program at Ayawilca are to focus on high-grade zinc mineralization and to increase the measured and indicated zinc mineral assets. Indicated assets are at present estimated at 19.0 Mt grading 7.2% Zn, 17 g/t Ag & 0.2% Pb and inferred assets are 47.9 Mt @ 5.4% Zn, 20 g/t Ag & 0.4% Pb (dated August 30^th, 2021). Determine 1 reveals a location map of the 2022 drill holes on the Ayawilca undertaking.

As outlined on this information launch, 4 holes have been drilled to check the geometry of the mineralization at West Ayawilca and higher outline the higher and decrease contacts of the huge sulphide zones. The 4 holes are positioned on three totally different east-to-west cross sections roughly 100 metres aside by way of West Ayawilca (see Determine 1).

Gap A22-193 was drilled to the east to check the extension of the West zinc zone mineralization. A zone of high-grade silver, related to disseminated pyrite and base metallic mineralization, was discovered at a comparatively shallow depth, yielding 5.75 metres grading 567 g/t silver, 0.17 g/t gold and 1% zinc+lead from 168.25 metres. Solely minor zinc was intersected; nonetheless, a slim zone of tin mineralization was intersected close to the bottom of the outlet (Determine 2A).

Gap A22-197 was drilled to the west on the identical part as A22-193, to check the continuity of zinc mineralization beforehand 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, together with a high-grade interval of 26.3 metres at 8.4% zinc related to sulphide substitute of limestone breccia. A follow-up gap is at present in progress (see cross part, Determine 2A).

Gap A22-198 was angled to the west on a bit 100 metres north of A22-197 (see Determine 1). This gap intersected 37.0 metres at 5.2% zinc inside a banded limestone unit related to magnetite alteration.

Gap A22-200 was drilled an additional 100 m to the north, to check 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 the most effective zinc zone intervals ever drilled at West Ayawilca – 44.9 metres at 12.0% zinc – proving the continuity of the high-grade huge sulphide zinc mineralization inside the decrease banded limestone. A follow-up gap is deliberate (see cross part, Determine 2B).

Notes on sampling and assaying

Drill holes are diamond HQ dimension core holes with recoveries typically above 80% and infrequently near 100%. The drill core is marked up, logged, and photographed on website. The cores are lower in half on the Firm’s core storage facility, with half-cores saved as a future reference. Half-core was bagged on common over 1 to 2 metre composite intervals and despatched to ALS and SGS laboratories in Lima for assay in batches. Requirements and blanks have been inserted by Tinka into every batch previous to departure from the core storage services. On the laboratory samples are dried, crushed to 100% passing 2mm, then 500 grams pulverized for multi-element evaluation by ICPMS utilizing multi-acid digestion. Samples assaying over 1% zinc, lead, or copper and over 100 g/t silver have been re-assayed utilizing exact ore-grade AAS strategies. Samples inside huge sulphide zones have been additionally assayed for tin utilizing XRF strategies.
