Tinka Resources Limited (TSXV: TK | BVL: TK | OTCQB: TKRFF) has announced results for five holes in the company’s ongoing 2022 drill programme at its Ayawilca project in Central Peru.
Dr. Graham Carman, Tinka’s president, and CEO stated: “The zinc grades intercepted in drill hole A22-195 are exceptional, backing up our belief that the Zinc Zone at South Ayawilca remains open along strike to the northeast. Drilling for the rest of 2022 will target additional high-grade zinc mineralization and an increase in the Measured and Indicated zinc resources at South and West Ayawilca. A second drill rig, which we expect to mobilize within the next few days, will speed up the drilling and enable the Company to drill simultaneously at both South and West Ayawilca.”
The results reported are for three resource extension holes that were drilled in the South Ayawilca area (A22-192, 194, and 195), and two exploration holes in the Central Ayawilca area (A22-190 and 191). Tinka has stated that results are pending for two holes (A22-193 and 196) and the eighth drill hole in the programme, A22-197, is in progress.
The company has approximately 10 to 12 more drill holes are planned in its zinc resource definition programme.
Tinka reported that its drill hole A22-195 returned very high-grade zinc results (6m grading 18.8% zinc) within a repeated section of favourable limestone, approximately 10m below the main contact with the basement phyllite. This high-grade zinc discovery is expected to extend the Zinc Zone indicated resource at the South Ayawilca area by around 60m to the northeast, with mineralization remaining open in that direction. Previous holes in the vicinity may have been stopped prematurely and did not test the lateral continuity of the repeated limestone in the basement.
In another positive development for the programme, strong tin-copper mineralization was also intersected underneath zinc mineralization in hole A22-190 at Central Ayawilca (32m grading 0.36% tin, 0.33% copper, and 13g/t silver), confirming the tenor of a previous drill hole intersection (48m grading 0.47% tin and 0.20% copper in hole A15-043). The tin-copper mineralization occurs as cassiterite and chalcopyrite in massive iron sulphide replacement bodies hosted in limestone, and as vein-style stockwork mineralization in underlying phyllite. Tin Zone mineralization at Central Ayawilca is interpreted to plunge northwards at a shallow angle and is open at depth.
Key highlights:
- South Ayawilca Zinc Zone resource extensions:
A22-195: 6.0m at 18.8% zinc from 392.6m depth including 3m at 27.7% zinc from 395.9m.
A22-194: 26.8m at 4.2% zinc from 293.0m depth including 1.0m at 31.6% zinc from 310.1m.
A22-192: 16.7m at 3.2% zinc, 0.4% lead and 18 g/t silver from 312.3m depth. - Central Ayawilca zinc exploration:
A22-191: 36.8m at 3.6% zinc from 264.0 metres depth including 6.3m at 6.0% zinc from 264.0 m.
A22-190: 17.9m at 3.1% zinc, 0.2% lead and 10g/t silver from 330.4m depth. - Tin Zone exploration:
A22-190: 32.0m at 0.36% tin, 0.33% copper and 13 g/t silver from 398m depth, including 9.4m at 0.52% tin, 0.28% copper and 11 g/t silver from 412.7m.
