Interra Copper Announces Encouraging Initial Results from 12-hole, 2,783 Metre Diamond Drilling Program
Interra Copper Announces Encouraging Initial Results from
12-hole, 2,783 Metre Diamond Drilling Program
October 17, 2021 Vancouver, BC – Interra Copper Corp. (CSE: IMCX) (OTCQB: IMIMF) (FRA:
3MX) (“Interra” or the “Company”) is pleased to announce initial 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 TH21-1, TH21-2 and TH21-5, which tested the northern portion of the
Cathedral Zone’s IP chargeability anomaly. All three holes intersected indicator low grade copper-
gold and moderate grades of molybdenum mineralization. Mineralization styles intersected within
the drill holes consists of disseminated, vein and localized semi-massive copper mineralization at
shallow to moderate depths within the Cathedral Zone. Localized quartz-chalcopyrite-
molybdenum fractures and vein mineralization has also been intersected within the drill ing
campaign. Significant mineralized intervals include:
TH21-01
• 5.07 meters1 of 0.14% Copper, or 0.23% CuEq2 ;
• 1.0 meter1 of 0.64% Copper, 0.03 g/t Gold, 1.2 g/t Silver and 1.7 ppm Molybdenum; and
• 1.0 meter1 of 0.57% Copper, 0.29 g/t Gold, 3.9 g/t Silver and 4.5 ppm Molybdenum;
TH21-02
• 14.90 meters1 of 0.17% Copper, 0.05 g/t Gold, 0.6 g/t Silver and 16.9 ppm Molybdenum,
or 0.36% CuEq2 and containing:
• 0.72 meters of 0.89% Copper, 0.31 g/t Gold, 2.5 g/t Silver and 4.8 ppm Molybdenum, or
1.16% CuEq2; and
• 5.50 meters1 of 0.14% Copper, 0.08 g/t Gold, 1.0 g/t Silver and 13.1 ppm Molybdenum, or
0.31% CuEq2 and containing:
• 0.30 meters of 1.41% Copper, 0.98 g/t Gold, 9.3 g/t Silver and 42.7 ppm Molybdenum,
or 2.53% CuEq2.
TH21-05
• 18.53 meters1 of 0.09% Copper, 0.05 g/t Gold, 0.7 g/t Silver and 4.1 ppm Molybdenum, or
0.16% CuEq2;
• 2.80 meters1 of 0.54% Copper, 0.14 g/t Gold, 2.7 g/t Silver and 20.6 ppm Molybdenum, or
0.82% CuEq2 and containing:
• 0.64 meters1 of 1.84% Copper, 0.45 g/t Gold, 9.5 g/t Silver and 73.7 ppm Molybdenum, or
2.83% CuEq2; and
• 1.26 meters1 of 187.1 ppm Molybdenum, or 1. 68% CuEq 2, containing 0.74 meters 1 of
308.5 ppm Molybdenum, or 2.8% CuEq2.
Drilling within the Cathedral Zone was focused on the following:
• to test a 600 square meter IP chargeability high (up to 45 mV/V with a background of 5)
within a highly K-spar and albite altered and resistive diorite to monzonite host;
• coincident surface copper-gold outcrop mineralization (ranging from 0.5 to 1.20% copper)
within magnetic high and low areas; and
• localized increased copper (<900ppm) -gold (<500ppm) -arsenic (<30ppm) soil analysis
on four east-west trending and 2 north south trending IP/soil lines.
A plan map and cross section of these holes with drill results are included below. See figure 3 for
plan view of relevant drill holes, and figures 4 and 5 for section view of the drill holes illustrating
the mineralized intercepts.
Interra’s goals at the Cathedral Area in 2021 included:
• confirming and expanding copper and gold mineralization at depth from previous surface
exploration programs;
• testing sub-surface chargeability and resistive high 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.
Our results to date have confirmed:
• porphyry related K -spar and albite alteration and structurally controlled quartz -sulphide
vein style mineralization is observed at depth at Cathedral;
• copper-gold and molybdenum mineralization is coincident with sub -surface high
chargeability and K -spar-albite-quartz altered highly resistive areas observed within the
2019 and 2020 IP programs;
• sulphides of pyrite, chalcopyrite and localized chalcocite and bornite occur as quartz -
sulphide veins and fractures (See Figure 1) and disseminations (Figure 2), proximal to
intrusive contacts, shear structures and within localized magnetite veins and breccias
• copper and gold mineralization at depth is at reduced grades to samples collected from
the surface, which may be due to secondary supe rgene enrichment of the surface
samples;
• mineralization and associated alteration within the reported intervals above are hosted
within the Thane Creek diorite (207 and 194Ma) and the Duckling Creek monzonite to
syenite (182 and 175Ma) intrusive phases of the Hogem Batholith;
• both sulphides and magnetite are noted to occur within areas of high chargeability and
equally within areas of magnetic high and magnetite destructive low areas; and
• mineralization within Thane and Duckling Creek suites of rocks may be related to late
Mesilinka granitic intrusive phases (135 to 128 Ma).
Results from the remaining drill holes within the Cathedral Area are pending and will be released
later this month and next.
Chief Executive Officer Jason Nickel states, “This drill program represents the first ever drilling at
the Cathedral Area and the first significant drilling on the Thane property. We view these as highly
encouraging results - targeting the first of five identified highly -prospective bulk -deposit style
copper-gold targets on the project and furthering our thesis that we are in proximity to a potentially
larger porphyry system.”

1 True widths of the reported mineralized intervals have not been determined.
2 Assumptions used in USD for the copper equivalent calculation were metal prices of $3.25/lb. Copper, $1,650/oz
Gold, $20/oz Silver, and USD $40/ lb Molybdenum; Recovery is assumed to be 100% / even par given no current
metallurgical testing at Thane to date. The following equation was used to calculate copper equivalence: CuEq =
Copper (%) + (Gold (g/t) x 0.74) + (Silver (g/t) x 0.0090) + (Molybdenum (ppb) x 0.60)
