NorthWest Copper Announces Start of 2024 Lorraine – Top Cat Exploration Drill Program

4 July 2024

NorthWest Copper


NorthWest Copper report that crews have mobilized to the field and drilling is expected to begin mid-July at the Lorraine-Top Cat project in north-central British Columbia. This is the first drill program for NorthWest in 2024. It is an integral component of the Company’s shareholder value objective to grow our mineral resource base via exploration.

Approximately 1,000 meters (“m”) of drilling is planned at Lorraine-Top Cat and the proposed holes will focus on the regional Nova and Road IP Targets (Figure 1). Both targets have potential to discover mineralization in areas outside of the current Lorraine mineral resource estimate (“MRE”) (indicated resources of 12.952 million tonnes (“Mt”) grading 0.55% copper (“Cu”) and 0.16 g/t gold (“Au”), and inferred resources of 45.252 Mt grading 0.43% Cu and 0.10 g/t Au at 0.20% copper cut-off grade .

Road IP Target

The Road IP Target is a geophysical and geochemical target 13 kilometer (“km”) to the north of the Lorraine MRE and is within the same valley as the Nova Target. This target comprises a coincident magnetic low with internal magnetic high, induced polarization (IP) chargeability high, and Cu-Mo Ah soil and silt anomalies . The Road IP Target model is that of a calc-alkaline porphyry system hosted by intrusions of the Hogem batholith, a deposit style that may exhibit geophysical and geochemical patterns that differ from targets in the Ducking Creek Syenite Complex, such as the Lorraine MRE. The Road IP Target occupies flat, low-lying ground, and is covered by an estimated (by the BCGS) 15 m of till. The target is bisected by and is accessible via the Upper Osilinka Forest Service Road.

Nova Target

The Nova Target is a geophysical feature consisting of coincident magnetic and IP chargeability highs. The strongest magnetic response measures approximately 400 x 200 m. Nova is approximately 10 km northeast of the Road IP Target. A boulder of pyroxenite altered to skarn collected from a borrow-pit along the road that crosses the Target returned high concentrations of Cu-Au-Ag-Pt-Pd of 1.39% Cu, 0.69 g/t Au, 6.45 g/t Ag, 0.21 g/t Pt and 1.398 g/t Pd. It is important to note that this potentially transported sample may not be representative of underlying bedrock. Thin section analysis by Dr. John Payne in 2019 described it as:

“Massive skarn dominated by actinolite with lesser magnetite-(ilmenite) and apatite, with a few skeletal interstitial grains of hornblende, scattered patches of chalcopyrite and much less abundant bornite (altered slightly to completely to covellite), and minor biotite and chlorite.”

The Nova Target occupies flat, low-lying ground, and is covered by till. It is bisected by the Upper Osilinka Forest Service Road, making the target easily accessible.

The Lorraine-Top Cat Project

The Project covers 65,000 ha and is located in north-central British Columbia, 280 km northwest of Prince George, BC and approximately 45 km from NorthWest’s Kwanika-Stardust Project. The Lorraine deposit is a silica-undersaturated alkalic copper-gold porphyry deposit, which is the same classification as the Galore Creek and Mount Polley deposits. Mineralization at the Lorraine – Top Cat Project is hosted mostly by Early Jurassic syenite and pyroxenite intrusions that are part of the Duckling Creek Syenite Complex (“DCSC”), but additional targets such as Road IP are associated with other phases of the Jurassic Hogem batholith or with older Takla Group volcanic rocks. A modern mineral resource estimate (MRE) was completed for portions of the Lorraine deposit in 2022 that includes indicated resources of 12.952 Mt grading 0.55% Cu and 0.16 g/t Au, and inferred resources of 45.252 Mt grading 0.43% Cu and 0.10 g/t Au at 0.20% copper cut-off grade. As described in previous disclosures, however, gold concentration is likely understated and silver was not included in the estimation because many historical drill holes were inconsistently analyzed for the two metals. The MRE extends to surface and includes the Lower Main, Upper Main, and Bishop Zones and intervening rock. Copper sulphides manifest various combinations of chalcopyrite, bornite and hypogene chalcocite, and the concentration of pyrite is generally low. Gold and silver, where analyzed, are spatially related to the copper mineralization, and elevated concentrations of platinum and palladium have been reported in several published papers.

Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources estimated will be converted into Mineral Reserves in future. There has been insufficient exploration to define the inferred resources tabulated above as an indicated or measured mineral resource, however, it is reasonably expected that the majority of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. The estimate of Mineral Resources may be materially affected by geology, environment, permitting, legal, title, taxation, sociopolitical, marketing or other relevant issues. Inferred Mineral Resources have a great amount of uncertainty as to their existence and as to whether they can be mined economically.
