NorthWest Copper Identifies Lorraine Boundary Target

VANCOUVER, July 06, 2023 - NorthWest Copper ("NorthWest" or "the Company") (TSX-V: NWST) (OTCQX: NWCCF) is pleased to announce that it has identified a prospective drill target area approximately 6.5 kilometres northwest of the Lorraine deposit¹. The Boundary Target is shown in Figures 1 & 2 and was identified by the NorthWest exploration team after a detailed review of newly compiled historical data. The target was identified primarily by new interpretations of:

• Magnetic and induced polarization geophysical surveys;
• Post-mineralization structures and their displacements;
• Surface rock geochemical results with values up to 11 % Cu, 60 g/t Au and 262 g/t Ag;
• Similar host geology and hydrothermal alteration to the Lower Main Zone at Lorraine; and
• A historical (1974), non-compliant resource of 7.2 Mt grading 0.55 % Cu and 3.7 g/t Ag² in the northern portion of the target area.
  

"The Boundary Target is another example³ of a high-priority exploration target in NorthWest's portfolio that we would plan to test in the next drill program at Lorraine," said Interim President and CEO David Moore. "Boundary has the potential to add near-surface mineralization only 6.5 km from the current Lorraine resource. The target has only been tested in a restricted area by a small number of relatively shallow historical drill holes. Our new interpretations of geology and structure in combination with historical geochemical and drilling results will be of great help in locating and orienting new drill holes in this exciting target. The Lorraine project offers many excellent target opportunities with potential to add to the project's resource base."
