Interra Copper Corp. announced further 2021 summer season drilling results from the Cathedral Area at its 20,600 hectare Thane Property, located on traditional territory of the Takla and Tsay Keh Dene First Nations in North-Central B.C. Results are from drill holes TH21-3, TH21-4, TH21-6, and TH21-12. TH21-3 and TH21-12 were designed to test the southern extent of a 600 square meter IP chargeability along line 5300N within the Cathedral Main zone. TH21-4 was drilled within the Cathedral South zone on the western extent of IP line 5200. TH21-6 was designed to test a broad, hidden, near surface 200 square meter IP chargeability anomaly approximately 350 meters to the east also on line 5300N. Drill holes intersected indicator low grade copper-gold mineralization. Anomalous mineralized intervals of significant copper (Cu), gold (Au), silver (Ag) or molybdenum (Mo) include: TH21-3: 20.65m of 0.08% Copper from 20.10 to 40.75m hole depth. TH21-4: 17.30 m of 0.05% copper, 0.03 ppm gold, 0.2 ppm silver and 7.20 ppm molybdenum from 108.20 to 125.50 m hole depth and a 0.08 Copper Equivalent ("CuEq") CuEq grade. TH21-6: 36.71 meters of indicator mineralization within an intercept from 120.0 m to 156.71m hole depth,
containing 0.07% copper, 0.5 ppm silver and 5.0 ppm molybdenum and a CuEq grade of 0.09%. TH21-12: 5.00 meters of indicator mineralization within an intercept from 113.35m to 118.35m hole depth, containing 0.21% copper, 0.07 ppm gold, 0.6 ppm silver and 23.6 ppm molybdenum and a CuEq grade of 0.28%. As with all other holes previously released, mineralization styles intersected within the drill holes consist of localized, structurally controlled, quartz-pyrite-chalcopyrite-±arsenopyrite fractures, veins and rare semi-massive mineralization at shallow to moderate depths proximal to diorite-(quartz) monzonite and latite porphyry contacts and south-southwest to south-southeast trending moderate to steeply (40-80°) westerly dipping chloritic shears and dilational breccias. Continued Drilling within the Cathedral Main and the Valley zones on 300N focused on the following; 100 meter step out to the south of TH21-1 and TH21-2 to further test mineralization within the 600 square meter IP chargeability high (up to 34 mV/V with a background of 5 mV/V) within highly K-spar and silica altered and resistive diorite to (quartz) monzonite and (quartz) syenite hosts; test a broad, blind, near surface 200 square meter IP chargeability anomaly approximately 350 meters to the east. Drilling within the Cathedral South zone on Line 5200N focused on the following; 350m step out to the west of the Cathedral Main zone chargeability targeted the depth extent of north-south trending, west dipping sheeted-stockwork actinolite-magnetite-pyrite-chalcopyrite mineralization and the potential for porphyry related potassic alteration and mineralization at depth below pervasive surficial sodic to sodic-calcic alteration within an associated chargeability low. A plan map and cross section of these holes with drill results are included below. Company's goals at the Cathedral Main, Cathedral South, and Valley Areas in 2021 included: confirming and expanding hidden copper and gold mineralization to the south, east, west and at depth from previous surface exploration programs; testing near sub-surface chargeability and resistive high and deeper resistive low targeted areas observed within the 2019 and 2020 IP programs; and drilling angled holes across interpreted porphyry related alteration and associated mineralization and structural zones.
