NorthWest Copper Identifies Kwanika Central Zone Transfer Target

VANCOUVER, June 21, 2023 - NorthWest Copper ("NorthWest" or "the Company") (TSX-V: NWST) (OTCQX: NWCCF) is pleased to announce that it has identified a highly prospective drill target approximately 500 metres south of the Kwanika Central Zone¹ (the "Transfer Target"). In recent months, the NorthWest exploration team has been reassessing the vast amount of exploration data available for Kwanika, which has resulted in the identification of new prospective areas. The Transfer Target is an exciting and tangible result of that ongoing work and is shown in Figures 1 and 2 below. The target was identified primarily by new interpretations of:

• The 3D induced polarization ("3DIP") survey completed in 2022;
• New models that reconstruct movement on post-mineral structures; and
• Alteration and metal zoning patterns.

"The Transfer Target is an excellent example of NorthWest's planned strategy to drill high-leverage exploration targets in 2023," said Interim President and CEO David Moore. "The Transfer Target has potential to add shallow, high-impact, open-pitable mineralization within the existing footprint of the Kwanika Project. The target can be tested by a small number of relatively shallow drill holes and is logistically easy to access. Projections of grade based on truncated resource blocks west of the Line Fault can be used to effectively target this drilling and suggest that the Transfer Target may represent the faulted offset of the Kwanika Central Zone. We are continuing to reassess our historical results to identify additional high-impact drill targets within our portfolio."
