NorthWest Copper Intersects 33.60% CuEq Over 9.40 Metres Within a 235.45 Metre Interval of 2.92% CuEq, Discovering a New Style of High-Grade Mineralization at Kwanika

October 27, 2021

VANCOUVER, British Columbia, Oct. 27, 2021 (GLOBE NEWSWIRE) -- NorthWest Copper (“NorthWest” or “the Company”) (TSX-V: NWST) (OTCQX: NWCCF) is pleased to announce that drillhole K-21-217 has returned the highest-grade Cu-Au interval ever intersected at Kwanika. The interval consists of massive to semi-massive copper and gold mineralization at moderate depth in the western half of the deposit. It expands the high-grade portion of the deposit, introducing a new style of mineralization. The drill intercept returned the following mineralized intervals:

  • 235.45 metres 1 of 2.92% copper equivalent (“CuEq”) 2 comprising 2.00% copper, 1.21 g/t gold and 5.3 g/t silver containing;
  • 153.25 metres of 4.13% CuEQ comprising 2.84% copper, 1.69 g/t gold and 7.5 g/t silver, further containing;
  • 9.40 metres of 33.60% CuEQ comprising 29.85% copper, 4.34 g/t gold and 70.5 g/t silver.

“This drill hole is a game changer for our Kwanika Deposit and for the region,” says Peter Bell, President & CEO. “The very high grade within a larger porphyry system is very unusual and establishes a brand new and incredibly exciting target type. We drilled one of the highest-grade drill holes reported globally in 2018, when DDH18-SD-421 intersected 100 metres of 5.30% CuEq, at our adjacent Stardust deposit. This new Kwanika drill hole is even higher-grade than drill hole 421 and occurs just 7 km away. The presence of such extraordinary grades in multiple deposits is both surprising and rare and opens up multiple, very high-grade exploration targets over a substantial area.”

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, $1,600/oz Gold, $20/oz Silver, and recovery is assumed to be 100% given the level of metallurgical test data available. The following equation was used to calculate copper equivalence: CuEq = Copper (%) + (Gold (g/t) x 0.7182) + (Silver (g/t) x 0.0090).

A plan map, figures and complete list of 2021 drill results are included below.

NorthWest’s goals at Kwanika in 2021 included expanding the high-grade zone and improving the grade within it by drilling angled holes across mineralized structural zones with closer-spaced drilling. Our results to date have exceeded our expectations, both expanding and improving the continuity and grade. This recent hole is higher grade than any previously drilled on our Kwanika property and importantly appears to be a new style of mineralization. The relationship of this new style of mineralization to the rest of the mineralization is not yet clear, but it adds another style of high-grade to the suite of exploration targets at Kwanika and the Company’s adjacent Stardust project.

NorthWest has focussed on the high-grade portion of Kwanika and adjacent high-grade Stardust deposit since the Company was created in March. Our previous Kwanika assay results 3 followed releases of favourable Stardust metallurgy in April 2021 4 and an expanded high-grade Stardust resource in May 2021. The near-surface results, drill hole K-21-217, and another set of deeper holes still to be released, will support an updated Kwanika resource planned for Q4 2021.

Copper-gold mineralization in the intervals reported below is hosted by diorite and monzonite intrusions and occurs disseminated through strong potassic alteration and in quartz-sulphide veins. Two late-mineral dykes cut the mineralization below 418.10 metres. The extremely high-grade interval from 326.65-336.05 metres consists of semi-massive to massive chalcocite/digenite, bornite, and covellite that form the matrix to a breccia. Breccia textures are locally preserved in this interval and the mechanism of its formation has not been determined. Within the middle of the high grade 9.40 metre interval, there was 1.20 metres of core that was ground and thus lost during the drilling process; for the purpose of the grade calculation this core was included within the calculation as zero grade over the 1.20 metre length.

A full table of K-21-217 results is provided below, along with a detailed breakdown of the grade distributions that make up these broader intersections:

Quality Assurance / Quality Control
Drilling completed at Kwanika in 2021 was supervised by on-site NorthWest personnel who collected and tracked samples and implemented a full QA/QC program using blanks, standards and duplicates to monitor analytical accuracy and precision. The samples were sealed on site and shipped to Bureau Veritas (BV) in Vancouver BC for analysis. BV’s quality control system complies with global certifications for Quality ISO9001:2008. Core samples were analyzed using a combination of BV’s MA200 process for low level concentrations (ICP-MS/4 Acid digestion) and the MA370 process for higher level concentrations (ICP-ES/4 acid digestion). Gold assaying was completed with FA430, a 30-gram fire assay with AAS finish. Base metal overlimits were finalized with titration, with gold overlimits completed with a gravimetric finish. A silica wash was used between high-grade samples to ensure no sample carry over.
