Tinka Resources Limited (TSXV & BVL: TK) (OTCQB: TKRFF) continues to grow a promising copper-gold discovery at its 100% owned zinc-silver and copper-gold projects in Central Peru.
Highlights:
Silvia NW copper-gold project:
- Copper-gold mineralisation at ‘Area A’ has been significantly expanded with the discovery of high-grade copper-gold veins (Skarn Veins) in limestone up to 100 metres across-strike from previously sampled mineralised skarn. The footprint of the skarn mineralisation now covers an area of 550 metres by 400 metres including areas of shallow cover;
- Skarn Veins grade up to 1.1% copper and 7.9 g/t gold from 17 grab and rock chip samples over intervals of 0.1 to 0.3 metres – individual samples range between 0.02% and 1.1% copper, and between 0.05 g/t and 7.4 g/t gold;
- Previous sampling across the original skarn discovery outcrop at Area A included 46 metres at 1.9 g/t gold and 0.8% copper, including 6.0 metres at 2.7% copper and 12.8 g/t gold;
- A preliminary mineralogical study of a high-grade copper-gold sample from Area A shows that gold occurs as fine-grained native gold up to 20 microns in size inside chalcopyrite, while primary copper mineralisation occurs almost entirely as chalcopyrite with trace amounts of late covellite;
- At Silvia NW, Areas A, B and C define a potential footprint of 3 x 1 kilometres. Sampling results from Area B (including trenches and soils) are currently being collated and interpreted by our technical team;
- Field work has commenced in preparation for an Environmental Impact Declaration to obtain the necessary permits for drilling at Silvia NW.
Ayawilca zinc-silver project:
- The company continues to advance its flagship Ayawilca zinc-silver project, following the update of the project’s PEA in October 2021, which highlighted the potential for Ayawilca to become a global top-10 zinc producer. Tinka is planning a resource extension and definition drill programme at South Ayawilca during the first half of 2022. Details of this programme will be announced soon.
“Tinka’s field work at Silvia NW continues to expand the scale of this exciting new copper-gold skarn prospect,” President and CEO, Dr Graham Carman, said.
“The discovery of Skarn Veins in the limestone surrounding the original discovery outcrop is very important because it shows that the mineralised system is significantly wider than previously thought.
“Skarn deposits in Peru have formed some of the largest and highest-grade copper deposits in the world, prime examples being Antamina (a global top-10 copper mine) some 90 km to our north, and Las Bambas in southern Peru.
“A preliminary mineralogical study of the copper-gold mineralization at Silvia NW shows that copper occurs almost exclusively as chalcopyrite, while gold appears to occur mostly in the form of fine-grained native gold.
“Also, the mineralisation at Zone A does not appear to contain significant levels of deleterious elements. Our team has continued its sampling and mapping programme at Areas B and C, and we look forward to reporting progress once all results are received.”
“At our flagship Ayawilca zinc-silver project, a geological reinterpretation of near vertical structures discovered at South Ayawilca in 2020 suggests that there is further potential to expand the high-grade silver-lead-zinc mineralisation.
“We are planning to commence a resource extension and definition drill programme during the first half of 2022, which will include drill holes aimed at expanding this style of mineralisation, ” Dr. Carman continued.
