IMCX:CC - Interra Announces Rip Phase One Drill Results Intersects Mineralized Porphyry System

(TheNewswire)

January 23, 2025, VANCOUVER, British Columbia – TheNewswire - Interra Copper Corp. (CSE: IMCX; OTCQB:IMIMF; FRA: 3MX) (“ Interra ” or the“ Company ”) is pleased to announce the results of the Phase Onedrilling program at the Rip Copper Project (the“ Project ” or “ Rip ”) in the Stikine region of BritishColumbia. The Rip Project is situated approximately 33 km northeast ofImperial Metals’ past producing Huckleberry copper-molybdenum(“ Cu-Mo ”) mine and Surge Copper’s advancedstage Ox/Seal/Berg projects. Imperial MetalsCorporation is exploring Huckleberry and its surrounding claims foradditional Cu-Mo resources.

Highlights of 2024 and the Rip PhaseOne Drilling:

• First phase drill testing at Rip has confirmed thatlargely covered geophysical targets define a Cu-Mo mineralizedporphyry system.

• Zones of anomalous Cu-Mo mineralization are hosted inmultiple phases of porphyritic intrusions and associated veinstockwork . Drill Intersection highlights include(*Table 1):

  • 0.102% CuEq over 126.6 m * in drill hole RP24-001 from 21.4 m

    • Including 0.267% CuEq over 24.6 m * from 21.4

  • 0.113% CuEq over 114.3 m * in drill hole RP24-002 from 33.6 m

• Two highly prospective, approximately 1 X 1 kilometre( km ”),annular geophysical anomalies remain largely untested

• most assays are anomalous in Cu-Mo and the presence ofintense quartz-sericite-pyrite alteration and strongly developed veinsets resembling D veins indicates the presence of a significantporphyry system that has only been partially tested.

• In 2024, acquired five additionalclaims by staking, more than doubling the initial 2,308.81 ha road accessible property to its current 4,770.65 hectares in a top tier exploration andmining district, the Bulkley Porphyry Belt.

In summary, the 2024 mag, IP and drill programsuccessfully resolved the original Rip anomaly into two separateporphyry systems and demonstrated that the northern target containsmultiple intrusive phases and long intervals of low-grade Cu-Momineralization. This northern target has been partly defined as a 600mwide subvertical cylindrical mineralized zone between a magneticbarren core and a chargeable pyrite halo. The northern target has onlybeen tested by three diamond drill holes (two by Interra in 2024, onehistorical in 1975). The southern geophysical target is equivalent insize to the northern anomaly and has no diamond drill testing.

Brian Thurston, President & CEOof Interra, commented : " Completion of the Phase One drill programhas successfully proven that a multi-phase, mineralized porphyrysystem is defined by the geophysical target interpreted byInterra with Cu-Momineralization intersected in both holes of this limited initial drillprogram. The drilling of this largely covered area has revealed that aportion of the northern target chargeability high is host toimpressive porphyry style stockwork that has potential to improve ingrade down plunge and laterally. The majority of the system, includingthe entirety of the southern target, remains untested and is highlydeserving of additional exploration. Interra has assembled a dominant landposition in the Bulkley Porphyry Belt and created a unique opportunitythat unlocks a district scale copper porphyry pursuit. "

Technical Details of the DrillProgram

Interra has received all assays from its two-hole, 1033metre drill program at the Rip Cu-Mo porphyry project in central BC.The Rip project is interpreted as a highly underexplored porphyryCu-Mo system that is predominantly covered by overburden. A smalloutcrop area contains variably altered porphyritic intrusions whichcut strongly hornfelsed Hazelton Group volcano-sedimentary rocks. Porphyritic intrusions and hornfelsedcountry rock are both host to porphyry style stockwork, includingmagnetite-chalcopyrite and quartz-chalcopyrite-molybdenite veins.Historical exploration drilling on the project included shallow,predominantly percussion holes targeting a large IP anomaly; withinthe IP anomaly, the holes intersected predominantly QSP alteredlithologies (including altered porphyritic intrusions) with anomalousCu-Mo mineralization. Multiple holes failed to reach bedrock.

An airborne magnetic survey flown earlier in 2024revealed for the first time two separate circular magnetic highswithin the historical chargeability high, suggesting that Rip containstwo porphyry centers. The southern mag high is significantly largerthan the northern one but does not crop out. Following the airbornemag survey, a 3D-DCIP induced polarization and resistivity survey wascompleted over the Rip target in 2024. The new IP survey resolved theoriginal 1980 chargeability anomaly into two chargeability“donuts” around the two separate magnetic highs, the classic“pyrite halo” signature of porphyry systems, providing moreevidence for the interpretation that Rip contains two adjacentporphyry systems.

Table 1. Summary of assay results

Notes on Table1 : Average of assays fromselected intervals with values continuously >500ppm CuEq, withallowance for inclusion of single sample gaps <500ppm CuEq. Theseintervals are mostly not considered to be ore grade, but rather areincluded to illustrate the extent of the mineralizing system. Cuequivalents are calculated based on the following US$ priceassumptions: copper US$4 per pound; gold US$2,500 per troy ounce;silver US$30 per troy ounce; and molybdenum US$20lb, assuming fullrecovery.

Two drill holes were completed on the northerngeophysical target from a single setup, both intersecting anomalous tolow-grade Cu-Mo porphyry mineralization from surface, and at depths>400m in RP24-001. Mineralization in both holes is hosted in threedistinct phases of porphyritic intrusions with potassic to phyllicalteration and multistage veining (e.g., magnetite-chalcopyrite;quartz-chalcopyrite-molybdenite, pyrite-chalcopyrite with sericitehaloes).

RP24-001 drilled eastwards towards the core of thegeophysical anomaly, targeting the magnetic high within the highchargeability ring. Between upper and lower mineralized zones lies acentral barren zone of strongly magnetic crowded porphyry (148-284m),major quartz pods and segregations (284-334m) and unidirectionalsolidification textures (“ USTs ”) (369-374m). These coincide with themagnetic high and are interpreted to comprise a central magmaticcupola near the magmatic-hydrothermal transition.

RP24-002 drilled westwards away from the core of thegeophysical anomaly, targeting the strongest portion of the highchargeability ring. Below an upper zone of weak Cu-Mo mineralization,the lower portions of the hole intersected strong to intensesericite-pyrite alteration with D-style veins but negligible Cu-Mo.This abundant pyrite alteration explains the chargeability ring and isinterpreted to be a portion of the pyrite halo of the northerntarget.

Interra Option Agreement and ClaimsAcquisition

In December 2023, the Company announced its optionagreement with ArcWest Exploration Inc. (“ ArcWest ”) toacquire up to an 80% interest in the Rip Cu-Mo project. Interra canearn the first 60% tier of its interest in the project by completingstaged exploration work totalling C$2.0 million and direct payment ofC$100,000 and annual share payments over four years until the end of2027.

In 2024 ArcWest and Interra added five additionalclaims to the option agreement, acquired by staking, more thandoubling the initial 2,308.81 ha road accessibleproperty to its current 4,770.65 has.

Assay Methods and QA/QC

The core was logged and sampled at the nearbyHuckleberry Mine by ArcWest personnel. A diamond saw was used to splitHQ diameter core in half, with one-half of the core put back in thecore box and the other half sampled. Samples were cut at a nominal 2minterval. One standard, one blank and one duplicate sample were addedto each batch of 30 samples. Samples were shipped by Bandstra directlyto the ALS Geochemistry prep lab in Terrace, BC. Final geochemicalanalysis was completed at the ALS Geochemistry lab in North Vancouver,BC using the methods PREP-31, ME-MS61, and Au-ICP21. Crush to 70% lessthan 2mm, riffle split off 250g, pulverise split to better than 85%passing 75 microns. Four acid digestion, ICP-MS finish, gold by fireassay. The standards, duplicate and blanks returned results within theexpected tolerances of the method.
