Noble Announces a Downhole Electromagnetic Survey Planned for 2 Drillholes in the Recent Timmins Area Diamond Drill Program

Toronto, Ontario – March 23, 2026

Noble Mineral Exploration Inc. (“Noble” or the “Company”) (TSX-V: NOB, FRANKFURT: NB7, OTCQB: NLPXF) has contracted Abitibi Geophysics to conduct a downhole Electromagnetics (BHEM) survey on 2 holes in the Carnegie Township area near Timmins, Ontario. The BHEM program is part of a 50/50 partnership with Canada 11530313 Canada Inc. and will include surveying 2 holes that were recently drilled in follow up of a drill program done in 2019.

The BHEM survey utilizes a single-loop configuration, where a large square transmitter loop measuring approximately 500 metres by 500 metres is laid out on surface. This loop generates a controlled electromagnetic field that penetrates the subsurface.

A total of two drill holes (CG-25-01 and 02) are being surveyed. Sensitive probes will be lowered down each borehole to measure the response of the surrounding rocks to the electromagnetic field.

This method is particularly effective at identifying off-hole conductive zones—potential mineralized bodies that may not have been intersected directly by drilling—thereby helping to refine future drill targets and improve exploration efficiency.

Drill Hole Results

In drill hole CG-25-01, a 6.5m section analyzed 0.64% zinc with associated anomalous values in copper, silver, and lead from 141.0 to 147.5 meters down hole (true width not known at this time). A 1-meter section within the wider section was found to run 1.90% zinc. The anomalous mineralization was found to occur in a weakly laminated sulphide rich graphitic sediment. Conductive mineralization consisted of about 5% pyrrhotite, with local concentrations of up to 10–15%.

Analyses on drill hole CG-25-02 have confirmed the presence of a polymetallic mineralized system similar to and assumed to be the same mineralized section as described above. The results define a polymetallic mineralized system, highlighted by:

• Up to 37 ppb gold and 4.6 g/t silver over 0.9m
• 0.65% zinc over 2.7m (with a high of 1.0%) and 0.13% copper over 1.9m
• Elevated nickel (up to 212 ppm) and cobalt (up to 189 ppm)
• True width not known at this time

The program is being carried out on lands recently transferred to Canada Nickel but on which Noble retains a 5-year Exploration Right for volcanogenic massive sulphide mineralization and precious metals.
