Tinka Drills Spectacular Hole at Ayawilca: 38.9 M @ 20% Zinc Including 10.4 M @ 42% Zinc

Tinka Resources Limited ("Tinka" or the "Company") (TSXV & BVL:TK)(OTCQB:TKRFF) is pleased to announce results for four drill holes from the Company's ongoing infill and resource expansion drill program at the Ayawilca zinc project in central Peru. All four drill holes are from South Ayawilca. Hole A22-202 has returned the best drill intercept ever made at the Ayawilca project: 38.9 metres grading 20.0% zinc including an ultra high-grade interval of 10.4 metres grading 42.0% zinc . The 2022-2023 drill program has now been expanded due to the excellent results to date, with about half of the drill holes (13) now reported of the estimated 30 holes to be completed at both South Ayawilca and West Ayawilca

Key highlights

  • Hole A22-202: 38.9 metres at 20.0% zinc from 170.5 metres depth, including
    • 10.4 metres at 42.0% zinc from 193.3 metres depth, including
      • 3.8 metres at 49.9% zinc from 198.0 metres depth.
    • The widest interval is the highest grade-thickness intercept ever drilled at Ayawilca.
    • Massive sulphide mineralization is concentrated in the hinge of a fold ‘anticline' at South Ayawilca.
    • Several fan-holes are now targeting extensions of this ultra high-grade zinc mineralization.
  • Hole A22-199: 5.3 metres at 14.3% zinc from 138.8 metres depth and 42.4 metres at 9.4% zinc from 246.5 metres, including:
    • 5.5 metres at 22.9% zinc from 261.3 metres depth, and
    • 9.1 metres at 20.8% zinc from 279.8 metres depth.
  • Hole A22-204: 14.8 metres at 8.4% zinc from 196.4 metres depth, including:
    • 6.1 metres at 12.6% zinc from 200 metres depth, and
    • 26.5 metres at 6.2% zinc from 264.5 metres depth, including
      • 3.9 metres at 15.1% zinc from 283.8 metres depth.

True thicknesses of the mineralized intercepts are estimated to be at least 75% of the downhole thicknesses.

The drill program at Ayawilca is continuing without interruption with two rigs operating 24/7. Around 7,000 metres have been completed with another 4,000 metres planned. Drilling is expected to continue until April 2023, with one rig at South and a second rig at West Ayawilca (where several holes have results pending).

Dr. Graham Carman, Tinka's President and CEO, stated: "The ultra high-grade zinc intercept in A22-202 is a potential game changer for the Ayawilca project. The interval of 10.4 metres grading 42% zinc consists of almost pure zinc sulphide mineralization, while part of this interval grading ~50% Zn is reflective of zinc concentrate grade accepted by smelters. Importantly, the mineralization is relatively shallow (~140 m depth) and comes from an area of the resource that could be accessed early in a mine plan. Several fan holes are in progress from the same drill platform (or from nearby sites) targeting extensions of this ultra high-grade zinc mineralization, particularly the limestone-sandstone footwall contact where the zinc appears to be concentrated. Two follow-up holes, A22-206 and A22-208, have already been completed and another hole is in progress".

Dr. Carman continued, "We are pleased to report that on the back of these excellent drill results to date, the 2022-2023 drill program has been extended to 11,000 metres. One drill rig continues to operate at South Ayawilca, with a second rig at West Ayawilca. We look forward to publishing more drill results as they come to hand from both areas."

Discussion of the drill results

Tinka has now completed approximately 7,000 metres (21 holes) in the 2022-2023 resource definition-expansion drill program with only 13 of the holes reported so far, including this release (see previous results dated Oct 11, 2022 and Nov 21, 2022 - drill hole map - Figure 1 ). The objectives of the drill program continue to be to target the highest-grade zinc mineralization at both South and West Ayawilca, and to expand measured and indicated zinc 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 (as at August 30 th , 2021).

Table 1 summarises the drill intercepts highlighted in this news release. Table 2 summarises the complete list of holes to date in the 2022 drill program.

Hole A22-202 was drilled to test the hinge zone of the limestone ‘anticline' fold previously identified at South Ayawilca. The hole intersected massive zinc sulphide mineralization over 38.9 metres grading 20.0% Zn from 170.5 metres depth (~140 metres vertical depth) - see cross section - Figure 2 . The interval of 10.4 metres at 42.0% zinc consists of almost pure zinc sulphide (sphalerite) mineralization - see drill core photograph - Figure 3 . The ultra high-grade zinc mineralization appears to be focussed along the limestone-sandstone footwall contact on the edge of the overturned anticline fold.

Hole A22-199 intersected two massive zinc sulphide intervals. The shallowest interval of 5.3 metres grading 14.3% zinc from 138.8 metres is hosted by sandstone. The deeper zinc interval is hosted by limestone and intersected 42.4 metres grading 9.4% zinc (including 5.5 metres grading 22.9% zinc and 9.1 metres grading 20.8% zinc). A third zone of sulphide (predominantly pyrrhotite hosted) intersected tin mineralization, including 18.0 metres grading 0.67% tin from 206 metres depth.

Hole A22-204 was drilled from a nearby drill collar targeting a gap in the indicated resource. This hole intersected two zones of high-grade zinc mineralization within the Pucara limestone, the best mineralized interval being 14.8 metres grading 8.4% zinc from 196.4 metres, including 6.1 metres grading 12.6% zinc. Another zone of sulphide intersected tin mineralization including 16.5 metres grading 0.36% tin from 234 metres depth associated with massive pyrrhotite - pyrite.

Hole A22-196 was a hole collared some 150 metres north of the South Ayawilca resource and was drilled at a shallow angle (45 degrees) to the south. This hole intersected moderate grade zinc mineralization in the uppermost part of the South Ayawilca deposit (18.6 metres grading 5.8% zinc from 300 metres depth) but missed the high-grade core of the deposit due to the shallow dip of the drill hole.

Note 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 SGS laboratory 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.

Zinc Price 2022 Year-End Review

Zinc prices had a strong start to 2022, hitting an all-time high during the first three months of the year.

However, zinc was unable to hold on to its gains, and ended the year hovering around the US$3,000 per metric ton (MT) mark — a level that is still quite high for the base metal used to galvanize steel.

Here the Investing News Network (INN) looks back at zinc trends for 2022, from supply and demand dynamics to how the metal performed and what analysts said quarter by quarter.

Zinc Stocks: 5 Biggest Canadian Companies in 2023

Base metal zinc continued to perform strongly in 2022. Prices hit a 15 year high in April, although they cooled later in the year, ultimately ending the period down US$604 per metric ton (MT).

Many of the base metals were hit with weakened demand in 2022 after China enacted its zero-COVID policy, and zinc was no exception. However, zinc supply also declined last year, with Russia's invasion of Ukraine further exacerbating Europe's energy crisis and causing some major zinc smelters and plants to suspend operations.

For investors interested in zinc, the Investing News Network has gathered the biggest TSX- and TSXV-listed zinc stocks by market cap. The list below includes zinc miners and explorers, as well as companies pursuing zinc as a secondary metal. Data was gathered on January 4, 2023, using TradingView’s stock screener, and only companies with market caps greater than C$50 million at that time were considered. Read on to learn more about their operations and plans.
