NorthWest Copper announced additional results from the 2022 Kwanika drilling program. K-22-255 has returned one of the longest and highest-grade copper-gold intervals ever completed at Kwanika. It was collared approximately 120 metres from hole K-21-217(1) and tested a similar area of the deposit.

K-21-217 encountered 235.45 metres of 2.65% copper equivalent ("CuEq")(2) . Importantly, this hole is characterized by a thick interval of strongly enriched gold grades within the copper zone. The bottom of the hole remains in copper and gold mineralization suggesting that the system potentially continues.

Results in this release were not included in the PEA(3) . NorthWest still has seven holes with outstanding assays at Kwanika from the 2022 program. Highlights from assays include: K-22-255:5: 399.80 metres4 at 1.01% CuEq from 152.20 metres: Inuding 23.40 metres at 2.51% CuCuEq from 152.60 metres; Including 151.00 metres of 1.55 g/t Au from 363.00 metres; Also including 64.00 metres at 2.12% CuEq from 374.80 metres; Also including 22.50 metres at 2.67% CuEq from 416.30 metres.

The hole shows a typical Kwanika pattern of copper dominant material higher in the hole then becoming much richer in gold at depth. Gold represents approximately 35% of annual revenue in the recent PEA at Kwanika-Stardust and K-22-255 demonstrates the strength of the gold system within the strong, continuous copper mineralization. K-22-255 This hole intersected 399.80 metres at 1.01% CuEq, including three higher grade intersections of 23.40 metres at 2.51% CuEq, 64.00 metres at 2.12% CuEq which includes 22.50 metres at 2.67% CuEq from 152.60 metres, 374.80 metres and 416.30 metres depth downhole respectively.

A strong gold interval of 151.00 metres of 1.55 g/t gold occurs within the overall copper-gold zone. K-22-255 was designed to test for high grade mineralization within the core of the proposed block cave(5) as well as collecting information on the controls of the high-grade mineralization and metal/geochemical information to better characterize the system. The drill passed through overburden to 33.60 metres depth, this was followed by moderately propylitic altered diorite with trace chalcopyrite mineralization occurring in veins more than disseminations to 152.20 metres.

It then passed through a 40-centimeter fault zone. After, and in, the fault, mineralization increases substantially as this is the start of the reported interval. The drill continued in a diorite with weak pervasive potassic alteration overprinting strong pervasive early biotite alteration to 294.00 metres.

Mineralization in this interval is dominated by disseminated chalcopyrite with some episodic zones of trace chalcocite accompanying the sulphides from 176.00 to 216.70 metres.
