Noble Mineral Exploration Inc. Updates NHSP Project with Detection of Significant Electromagnetic Anomaly

Toronto, Ontario — October 1, 2026 — Leads & Copy — Noble Mineral Exploration Inc. announced an update on its NHSP project in northern Quebec, highlighting the detection of a significant electromagnetic anomaly that could indicate valuable mineral deposits. The anomaly, approximately 800 meters by 700 meters, was identified through an AirTEM airborne survey completed in 2023 in the Havre St. Pierre region of Quebec.

This discovery is particularly significant as similar anomalies in the area, situated within the same geological environment, have previously led to the discovery of massive sulphide mineralization. These discoveries yielded good grades of copper and nickel, along with elevated levels of platinum, palladium, cobalt, and gold.

Noble has mobilized a field crew and helicopter to investigate the anomaly further. The area of interest is located near the contact of the Havre St Pierre Anorthositic Complex, the same geological setting where significant nickel, copper, and platinum group element (PGE) mineralization has been found. The company's claims encompass a portion of this complex, which is known to host such mineralization.

The geological structure of the Havre St. Pierre Anorthositic Complex is characterized by a sharp contrast between magnetic highs and extreme magnetic lows, typical of anorthosite formations. Nickel, copper, and PGE mineralization often accumulates near the intrusive contacts within these formations.

The 2023 AirTEM survey successfully pinpointed a 800-meter conductive zone associated with a magnetic high, situated on the margin of the anorthositic complex within Noble's claims. This conductive zone is located along the northeast contact margin of the area, as indicated by Figures 1 and 2, which illustrate the conductors on apparent conductivity and magnetic field backgrounds, respectively.
