Interra Copper Corp. (CSE: IMCX) (OTCQB: IMIMF) (FRA: 3MX) announces further Drilling Results from the Gully 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 TH21-7, TH21-8 and TH21-11 which tested the eastern portion of the Gully Zone’s IP chargeability anomaly along lines 4700N and 4600N respectively as well as the southern end of line 6350E. All three holes intersected indicator low grade copper-gold mineralization. Mineralization styles intersected within the drill holes consists 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. Significant mineralized intervals anomalous in some or all of Cu, Au, Ag, Mo include:
24.5 meters of indicator low grade copper-gold intercept from 70.0 m to 94.5 m, with an average grade of 0.13% Cu, 0.03 ppm gold, and 4.1 ppm molybdenum, and a CuEq of 0.15% CuEq.
TH21-8 contains two indicator style low grade copper-gold intercepts, 19.4 meters of 0.05% CuEq and 34.5m of 0.04% CuEq,
a low grade indicator style copper gold intercept, a 10.5m composite interval from 82.5 m to 93.0 m, grading 0.14% Cu, 0.07 ppm gold, 0.7 ppm silver and 5.5 ppm molybdenum.
See Table 1 for the chart format of these intercepts and CuEq calculation, and Figure 6 for Drill hole cross sections.
Table 1 – Chart of Composite intervals and Copper Equivalent Calculations.
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 (ppm) x 0.0006)
Drilling at the Gully Zone tested the depth potential of the following surface results:
A plan map and cross section of these holes with drill results are included below. See figure 4 for plan view of relevant drill holes, and figures 5 and 6 for section view of the drill holes illustrating the mineralized intercepts.
