PROBE GOLD AND MIDLAND REPORT POSITIVE MMI SOIL SAMPLING RESULTS ON THE LA PELTRIE CU-AU-AG-MO MINERALIZED SYSTEM, DETOUR QUEBEC

Probe Gold Inc., in partnership with Midland Exploration Inc., has provided new results from its 2024 MMI (mobile metal ion) soil sampling program completed on the La Peltrie project. The MMI sampling grid, totalling 786 soil samples, covers the main copper-gold-silver-molybdenum discovery that returned a massive intersection of 0.13 per cent copper over 513.5 metres (see press release by Probe dated Jan. 22, 2024). The soil samples were taken at a spacing of 50 metres and 100 metres along sampling lines spaced 200 metres to 400 metres apart and extend northward to cover the southern contact of the Carheil intrusion. This soil sampling grid successfully identified the main copper-gold-silver-molybdenum zone and extended the latter westward by at least 1,800 metres.

Highlights:

• Eight values above 10,000 parts per billion copper, with high of 31,100 parts per billion copper;
• 96 values above 2,000 parts per billion copper and 15 values above 100 parts per billion molybdenum;
• MMI copper values outline the main copper-gold-silver-molybdenum zone and also delineate at least 1,800 metres of untested potential to the west.
• Multiple new Cu-Mo-Ag soil anomaly trends identified to the north and northeast, proximal to the contact between volcanic rocks and the Carheil intrusion;
• Results to date continue to indicate the potential for a highly prospective and extensive mineralized system that remains open along strike and at depth, requiring detailed follow-up.

Dr. David Palmer, president and chief executive officer of Probe, stated: "Our ongoing exploration programs at Detour continue to highlight the tremendous potential of this district-scale project. The soil program has been very successful in not only delineating the copper-gold discovery but also demonstrating the potential for a very extensive system of mineralization and possible enrichment to the west. We are now preparing for our 2025 programs, which will see an expansion of the soil program, follow-up geophysics and drilling to test the new targets we are generating. Given the results we are seeing, Detour is definitely going to be one of the priorities in our regional exploration program for 2025."

During the months of June and July, Probe completed a systematic MMI soil sampling survey, totalling 786 soil samples, covering the main copper-gold-silver-molybdenum discovery and extending north to cover the Carheil intrusion. The focus of the program was to identify additional zones of copper mineralization and vector toward a potential higher-grade source surrounding the Carheil intrusion. The MMI soil anomalies were spatially coincident with the new copper-gold-silver-molybdenum zone with additional anomalous trends extending to the north and west of the discovery. A total of eight values were above 10,000 parts per billion copper, reaching up to 31,100 parts per billion copper; 96 values were above 2,000 parts per billion copper; and 15 values were above 100 parts per billion molybdenum. Additionally, subparallel trends to the north of returned 11,900 parts per billion copper, 62 parts per billion molybdenum, 0.3 part per billion gold and 10 parts per billion silver proximal to the contact between volcanic rocks and the Carheil intrusion. Samples were taken at a spacing of 50 meres along sampling lines spaced 200 metres apart over the discovery zone and contact to the Carheil intrusion. Samples taken over the Carheil intrusion were taken at 100-metre spacing along 400-metre-spaced lines.

Anomalous MMI values to the north and northeast show a strong correlation with existing copper-molybdenum-silver values in isolated prospecting samples collected in 2020 and 2023. Several of these anomalous areas also correlate with the best IP (induced polarization) anomalies from the survey conducted last March and have yet to be drill tested.

SRK Consulting has performed a structural analysis of the high-resolution aeromagnetic survey conducted in 2020 and data have shown good correlation of structures to copper-gold-silver-molybdenum mineralization. To date, fault structures (first order, second order, third order and fourth order) have been established from the data. The objective of this structural analysis of the project is to improve the structural and geological understanding of the copper mineralized zone, looking at the geometry of structures, generations and distribution of fault/shear zones, and generations of folds. The study covers the copper discovery and extends northward to cover the Carheil intrusion.

The structural interpretation, MMI survey, drilling and IP survey will be used to identify highly prospective areas associated with copper-gold-silver-molybdenum mineralization for a coming drilling program that is currently in preparation.

A preliminary interpretation of results received to date suggests that combined copper-gold-silver-molybdenum grades tend to increase from east to west. This indicates a potential vector of enrichment west of drill hole LAP-22-12_EXT in an area that has not been tested. Base metal mineralization is associated with a massive to pillowed, fine-grained basalt unit. The basalt is carbonatized and pillow selvages have strong chlorite and epidote alteration. The volcanic unit is crosscut by centimetre-scale quartz veins with blocky potassium feldspar within the veins and strong potassic epidote alteration halos. Local hydrothermal breccia zones have strong albite and silica altered angular clasts in a quartz/carbonate matrix. Quartz veining and brecciated zones host up to 25 per cent sulphides as veinlets and blebby intergrowths of chalcopyrite and pyrrhotite.

Based on these results, the company is currently preparing an exploration program in order to resume follow-up drilling on this new discovery.

Probe's Detour Quebec project

The discovery-stage project covers an area of 777 square kilometres along the Detour gold trend, including the La Peltrie property option, the Gaudet-Fenelon joint venture property, and the wholly owned Detour Quebec Main and North properties, and is located 190 kilometres north of Rouyn-Noranda and 40 kilometres northwest of the town of Matagami, Que., and hosts the Sunday Lake, Massicotte and Lower Detour Lake gold deformation zones. Both the La Petrie option and Gaudet-Fenelon joint venture properties are in partnership with Midland Exploration. The project is located along the lateral extensions of Canada's second-largest gold mine at Detour Lake, operated by Agnico Eagle Mines Ltd., and recent high-grade gold discoveries in Zone 58N, Fenelon/Tabasco, Area 51 and Martiniere/Bug Lake made by Balmoral Resources Ltd. and subsequently its acquirer, Wallbridge Mining Company Ltd., on its land package adjacent to the northern boundary of Probe's property.

Quality control

All 2024 MMI soil samples were collected under the supervision of Probe employees. At each sample site, a small pit is dug to evaluate the soil profile, the sample is extracted using an auger, placed in the sample bag with a numbered tag to maintain chain of custody and closed with a zip tie until it reaches the laboratory for analysis. Approximately 500 grams of material are extracted at an average depth of 10 to 15 centimetres below the organic/inorganic interface as outlined by SGS Canada's MMI sampling protocol. At each sample site, a GPS (Global Positioning System) location, photograph, sample site characteristics and sample composition are documented. A strict quality assurance/quality control program was applied during sample analysis; which includes a field duplicate every 50 samples and insertion of mineralized standards and blank samples for each batch of 50 samples. Samples were sent to SGS Canada in Burnaby, B.C., for mobile metal ion (MMI) leach using inductively couple plasma mass spectrometry (ICP-MS) analysis on 50 grams of material completed using a 55-element geochemical package.
