NorthWest Copper (TSX-V: NWST) (OTCQX: NWCCF) is pleased to announce receipt of the second set of assays from its ongoing 2022 Kwanika drill program, which highlight the discovery of additional very high-grade copper and gold mineralization within a previously undrilled shallow area of the Kwanika deposit. Hole K-21-232 contains intervals of “chalcocite breccia” mineralization (see below) with similar geology to last years 33.60% Copper Equivalent (“CuEq”) over 9.40 metres in hole K-21-217

Highlights from the recent set of assays include:

• K-22-230: 378.80 metres of 0.62% CuEq from 19.20 metres.
• K-22-232: 109.05 metres of 0.89% CuEq from 27.00 metres, including:
• 1.45 metres of 14.52% CuEq.
• K-22-233: 102.90 metres of 1.00% CuEq from 30.00 metres, including:
• 2.00 metres of 4.06% CuEq .

“The high-level objectives of the 2022 Kwanika drill program are to grow the size of the resource and to improve the grade. One of the targets is to find additional very high-grade copper and gold mineralization as encountered in drill hole K-21-217 in 2021,” said Peter Bell, President and CEO. “We believe we have found more of this material in hole K-22-232 and have named this type of mineralization “chalcocite breccia”. While the new interval is narrower than last year’s hole, it is much closer to surface and suggests potential for multiple very high-grade zones within the deposit.”

“The discovery of additional high-grade chalcocite breccia in a new area, close to surface, is an exciting exploration development for NorthWest at Kwanika,” continued Mr. Bell. “This drilling supports our thesis that we can find more of this style of mineralization while expanding the volume of near-surface mineralization at Kwanika.”

Chalcocite Breccia
Chalcocite breccia is a distinctive rock type observed at Kwanika comprised of fragments of mineralized wall rock within a background of finer grained chalcocite, chalcopyrite and sometimes bornite. Importantly, chalcocite is a very high-grade copper mineral, comprised of 80% copper by weight. This chalcocite breccia has been observed in holes K-21-217 and K-22-232 (See Figure 1).

Drill Results Discussion
Kwanika and the adjacent Stardust deposit are the current flagship projects at NorthWest. The 2022 Kwanika drill program includes holes designed to expand the known resource, to add new high-grade zones within and around the known resource, and to test for new centres of mineralization regionally. Similarly, to the first set of drill results, these four holes (Figure 2) targeted expansion and delineation of near surface high-grade zones in the southern part of the Kwanika Central Zone. Kwanika drilling has been underway since March 25, with a total of 28 holes and 11,089 metres drilled to date. Results from seven of the holes have been reported so far, with the remainder outstanding.

Holes K-22-230, K-22-231, K-22-231 and K-22-233 are in the southern portion of the Central Zone (Figure 2). The drill holes were designed to test for shallow high-grade mineralization in an area with low drill density and to further constrain our structural model of the Kwanika Central Zone. All holes in this area hit high grade mineralization with intervals or sub-intervals with grades higher than 1.00% CuEq (Table 1).

K-22-230 (Figure 3) was drilled to the northeast at 330 and was designed to test in an area of lower drill density Kwanika Central Zone and test for structures to improve NorthWest’s structural model in the Central Zone. K-22-230 hit a broad intersection of 378.8 metres with 0.62% CuEq with a high-grade sub interval of 87.6 metres at 1.03% CuEq. The high-grade mineralization occurred in a zone of potassic altered monzonite with abundant quartz-sulphide veins and blebby chalcopyrite centered around the central fault.

K-22-231 (Figure 4) was drilled to the southeast, testing for high-grade mineralization at surface associated with the Central Fault Zone within the southern extent of the Central Zone in an area of low drill density. The drill collared into high-grade mineralization with 47.80 metres at 1.02% CuEq at surface below the till cover in potassic altered monzonite with hematite staining, quartz sulphide veins, blebs of native copper, chalcocite and trace bornite.

K-22-232 (Figure 5) was drilled from west to east, targeting high grade near surface mineralization associated with the Central Fault Zone in an area of low drill density. It cut through 109.05 metres at 0.89% CuEq with high-grade sub-intervals including 32.90 metres at 1.88% CuEq and 1.45 metres at 14.52% CuEq. The 1.45 meter at 14.52% CuEq is chalcocite breccia, similar to the style of mineralization observed in K-21-217 (9.40m at 33.60% CuEq).

K-22-233 (Figure 6) was the final hole drilled in this area during this campaign, as above it targeted high-grade mineralization in the southern extent of the Central Zone in area with low drill density. It returned 102.90m at 1.00% CuEq starting at the surface below the till cover. This includes a 2.00 meter sample of 4.06% CuEq at upper contact. The high-grade mineralization is hosted in a strongly potassic altered monzonite with stockwork quartz-sulphide veins.

Note: Interval reported for K-22-232 is 9.35% Cu, 6.65g/t Au, 44.1g/t Ag and 14.52% CuEq over 1.45 metres,  the weighted average of the individual assays shown in Figure 1 make up this interval. For K-21-217 the weighted average is shown over the reported 9.40 metre interval.
