Interra Copper Corp. Reports Further Anomalous Cathedral Main Zone Drill Results
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.
