VANCOUVER, BC / ACCESSWIRE / October 7, 2021 /Tinka Resources Limited(TSXV:TK) (“Tinka” or the “Company”) (BVL:TK) (OTCQB:TKRFF)is pleased to announce initial high grade copper-gold surface sampling results from the Silvia NW target, one of several prospective areas within the Company’s 100%-owned Silvia Project which was recently acquired (HERE).

Silvia NW is located in the Huanuco region of central Peru, 30 km from the Company’s flagship Ayawilca project and 90 km along strike south of the Antamina copper mine .

Silvia NW is prospective for copper-gold skarn mineralization along a 3 km x 1 km trend that has seen minimal exploration and no drilling.

Tinka’s detailed sampling at “Area A”, one of three mineralized zones at Silvia NW (see Figure 2), has discovered high-grade copper-gold mineralization associated with apparently continuous outcrops of skarn covering an area of approximately 400 metres by 100 metres, open in all directions.

Widespread scree intermittently covers the outcrops and has limited the lateral extent of this early sampling (see Figures 3, 4 & 5).

Highlights of sampling from Area A at Silvia NW:

• A total of 108 trench and rock chip samples were collected over a 400 m x 100 m area of semi-continuous skarn:
  • Average grade of all samples is 0.79% copper & 0.60 g/t gold (1.24% CuEQ*);
  • Copper ranges between 0.01% to 12.31% Cu, and gold ranges between 0.01 g/t to 18.60 g/t Au;
• There is a strong positive correlation between copper and gold;
• Copper occurs as chalcopyrite with chalcocite and covellite (and minor copper oxides) in green garnet-magnetite skarn associated with quartz feldspar porphyry (QFP) dikes – mineralization occurs in both limestone (“exoskarn”) and QFP (“endoskarn”);
• Skarn mineralization is open in all directions under shallow scree cover;
• Rock samples are representative, non-selective, trench or continuous rock chip samples (1-2m wide) covering various rock types including skarn, QFP and limestone;
• Exploration is continuing at Area A, B and C along the 3 km northeast-southwest trend.

Tinka Resources management comments

“We are very excited to announce the discovery of high grade copper-gold mineralization in our initial sampling at Silvia NW, located in an underexplored Andean region of central Peru close to our flagship Ayawilca project.

“We believe that these initial sampling results, covering a surface area of approximately 400 m x 100 m, show the outstanding potential for a large and high-grade skarn deposit that has previously not been recognized. The high levels of gold associated with the copper mineralization is a big positive, as gold significantly increases the potential value of the mineralization. The skarn remains open in all directions.”

“We believe that we could be seeing the early indications of a high potential, high quality copper-gold prospect at Silvia NW. Exploration is continuing at target Areas B and C with mapping and detailed sampling along the 3 km trend, where additional skarn bodies have been reported in both areas.”

“In addition to our current exploration activities, Tinka continues to advance its outstanding Ayawilca zinc-silver project which we believe is one of the best undeveloped zinc projects in the Americas. A Mineral Resource estimation update was recently released (see HERE).

A Preliminary Economic Assessment (PEA) for the Ayawilca deposit will be disclosed within weeks.”
