Probe Gold Intersects Grades Up to 3.1 g/t Au Over 17.0 Metres in Infill Drilling at Novador Project, Quebec

Highlights:

• Courvan Trend infill drilling results intersected near-surface gold zones with significant grades up to 6.2 g/t Au over 4.9 metres, including 26.8 g/t Au over 1.0 metres and thick gold zones, including an intersection of 3.1 g/t Au over 17.0 metres, including 14.1 g/t Au over 2.0 metres.
• The recently completed 50,000-metre winter infill drilling program was designed to support the upcoming 2025 Pre-Feasibility Study, which is expected by year-end.

TORONTO, June 17, 2025 (GLOBE NEWSWIRE) — Probe Gold Inc. (TSX: PRB) (OTCQB: PROBF) (“Probe” or the “Company”), is pleased to provide the latest results from the Novador in-fill drill program on its 100%-owned Novador property (the “Property”) located near Val-d’Or, Quebec. The 50,000-metre winter infill drill program, initiated during the fall of 2024, was designed to support the 2025 pre-feasibility study. Results from fifty-one (51) infill drill holes, totaling 8,405 metres, have returned significant gold intercepts from near-surface to approximately 200 metres vertical depth in the Bussiere and Creek deposit areas. (see figure 1 and table of selected drill results below).

David Palmer, President and CEO of Probe, states, “Once again the infill drilling program at Novador continues to deliver strong results, confirming continuity and highlighting significant expansion potential along strike and at depth at Courvan. These winter drill results will be instrumental in supporting resource conversion and will form a key foundation for the upcoming Pre-Feasibility Study, an important milestone in advancing Novador toward development.We’re making solid progress on multiple fronts, including permitting, resource expansion, and optimizing the mine plan. With a strong treasury we remain fully committed to establishing Novador as a top-tier gold development project. With every milestone, our confidence in Novador’s potential grows, supported by a clear and actionable path to production.”

These latest in-fill drilling results confirm vein continuity and will continue to enhance our 3D models.   The Courvan Bussière and Creek Zones remain open for significant expansion along strike and at depth.

Selected infill drill results from the Bussiere and Creek deposits drilling program are as follows:

(1) All the new analytical results reported in this release and in this table, are presented in core length and cut to 50 g/t Au when needed. True width is estimated between 65 to 95 % of core length. Only grade times thickness above 10.0 g/t Au * m is reported.

Mineralization along the Courvan trend, including Bussiere Mine sector, is characterized by a series of shallow-dipping East-West gold-bearing veins spatially associated with shear zones that intersect the Bourlamaque granodiorite batholith. The veins encountered containing gold are primarily composed of sulphide-bearing quartz-carbonate-tourmaline, and gold is typically associated with centimetre-scale pyrite masses within the veins. Gold mineralization intersected in the volcanics is associated with a shear zone and sulphide-bearing quartz-carbonate-tourmaline veins. The Bussiere deposit remains open laterally and at depth.

Qualified Person

The scientific and technical content of this press release has been prepared, reviewed, and approved by Mr. Marc Ducharme, P.Geo, Vice President Exploration, who is a “Qualified Person” as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

Quality Control

During the last drilling program, assay samples were taken from the NQ core by sawing the drill core in half, with one-half sent to a certified commercial laboratory and the other half retained for future reference. A strict QA/QC program was applied to all samples, which includes insertion of mineralized standards and blank samples for each batch of 20 samples. The gold analyses were completed by fire-assayed with an atomic absorption finish on 50 grams of materials. Repeats were carried out by fire-assay followed by gravimetric testing on each sample containing 3.0 g/t gold or more. Total gold analyses (Metallic Sieve) were carried out on the samples which presented a great variation of their gold contents or the presence of visible gold.

About Probe’s Novador Project

Since 2016, Probe Gold has been consolidating its land position in the highly prospective Val d’Or East area in the province of Quebec with a district-scale land package of 835 square kilometres that represents one of the largest land holdings in the Val-d’Or mining camp. The Novador project represents one property block of 202 square kilometres that hosts four past producing mines (Beliveau Mine, Bussiere Mine, Monique Mine and Beaufor Mine) and contains 80% of the Company’s gold resources in Val-d’Or East. Novador is situated in a politically stable and low-cost mining environment that hosts numerous active producers and mills.
