[{"type":"text","content":"Tinka Discovers High Grade Copper and Gold at Silvia Project - Surface Samples Up to 12.3% Copper and 18.6 G/T GoldVANCOUVER, BC / ACCESSWIRE / October 7, 2021 / Tinka Resources Limited (\"Tinka\" or the \"Company\") (TSXV:TK)(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 (see news release dated July 12, 2021). 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 (see Figure 1).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.Dr. Graham Carman, Tinka's President and CEO, stated: \"We are very excited to announce the discovery of high grade copper-gold mineralization in our i...
