Tinka Resources Limited (TSXV: TK | OTCQB: TKRFF) has announced results for the final three drill holes of the 11,000m 2022-2023 drill programme at South Ayawilca, and has provided an update on the company’s ongoing exploration activities.
The recent drill campaign at Ayawilca was completed at the end of May 2023. The company is now focused on completing a mineral resource update for the Ayawilca deposit and revising future mining scenarios via a desktop trade-off study. Exploration is also continuing at the company’s nearby Silvia copper-gold project.
Drill results from the Silver Zone at South Ayawilca were highly encouraging with a high-grade silver intercept in a 150m step-out in hole A22-195. The other two new holes reported here, A23-221 and A23-223, intersected high-grade Zinc Zone mineralization in resource confirmation holes.
Dr. Graham Carman, Tinka’s president, and CEO, stated, “We are pleased to report results from the final holes of the 11,000m drill programme at Ayawilca. These latest drill holes targeted both Zinc Zone massive sulphide mineralization and extensions of the structurally controlled epithermal Silver Zone mineralization on the edge of the massive zinc sulphides at South Ayawilca. All drill intersections have now been incorporated into a new geological model which will form the basis of an updated mineral resource estimation which we expect to be released in September 2023.”
Key highlights include:
Zinc Zone:
- Hole A23-223: 21.6m at 6.6% zinc and 18g/t silver from 254.0m depth, including
- 7.6m at 10.7% zinc and 18 g/t silver from 268.0m depth.
- Hole A23-221: 13.8m at 6.8% zinc from 290.2m depth.
Silver Zone:
- Hole A22-195: 3.4m at 465g/t silver from 209.7m in a 150m step-out hole.
- The Silver Zone is interpreted as a subvertical, northeast-trending structure with high-grade silver over a strike length of at least 500m on the northern edge of the zinc-rich massive sulphide bodies at South Ayawilca.
- Previous downhole intercepts of the Silver Zone include 7.1m at 604g/t silver and 11.5m at 781g/t silver.
- The Silver Zone mineralization remains open in all directions including up- and down-plunge
Furthermore, a drone magnetic survey was successfully completed at the Silvia NW copper-gold target, 30km west of Ayawilca. The geophysical data is currently being processed and interpreted.
