West Red Lake Gold Intersects 61.51 g/t Au over 12.1m, 43.54 g/t Au over 8.35m and 24.61 g/t Au over 11.2m at South Austin – Madsen Mine

Shane Williams, President & CEO, stated, “The South Austin zone has been producing very high grades and impressive widths in the definition drilling program to begin 2025 – often associated with the presence of visible gold. The team is successfully defining a panel of very high-grade mineralization in South Austin between 8L and 12L of the mine. It is becoming apparent that a lot of high-grade material was left behind in this area by historic operators and we are taking full advantage of this low hanging fruit that sits immediately adjacent to our existing underground development. These organic growth opportunities are exciting because they represent high margin ounces that can be sequenced into our mine plan very efficiently. As drilling progresses at depth we expect to uncover more areas of untapped potential and look forward to providing further updates as assay results continue to be received.”

These drill results are located approximately 50 meters (“m”) up-dip from the South Austin intercepts previously announced on February 26, 2025, where drilling returned 114.26 grams per tonne (“g/t”) gold (“Au”) over 10.6m, 77.90 g/t Au over 3m and 24.48 g/t Au over 8.5m (Figure 3). This area is also approximately 300 m up plunge from the drill results recently announced on May 13, 2025 where drilling returned 48.97 g/t Au over 18.7m, 52.86 g/t Au over 4.5m and 25.49 g/t Au over 7.5m (Figure 3). The South Austin zone continues to demonstrate significant grade and thickness potential at depth and along strike, which is being fully realized and accurately defined through definition drilling.

The purpose of this drilling was definition and expansion within priority areas of South Austin to continue adding to an already substantial inventory of high-confidence ounces to support the restart of production at the Madsen mine, which was announced on May 22, 2025. The Company reported positive results from its recently completed bulk sampling campaign on May 7, 2025, and also filed a Technical Report for its Pre-Feasibility Study for Madsen on February 18, 2025.

The South Austin Zone currently contains an Indicated mineral resource of 474,600 ounces (“oz”) grading 8.7 g/t Au within 1.7 million tonnes (“Mt”), with an additional Inferred resource of 31,800 oz grading 8.7 g/t Au within 0.1 Mt.

*The “From-To” intervals in Table 1 are denoting overall downhole length of the intercept. True thickness has not been calculated for these intercepts but is expected to be ≥ 70% of downhole thickness based on intercept angles observed in the drill core. Composite grades reported are uncapped. Internal dilution for composite intervals does not exceed 1m for samples grading <0.1 g/t Au.

DISCUSSION

Accessed through the Madsen Mine East Portal, the South Austin Zone sits south in the hanging wall of the main Austin Zone. Like the other mineralized domains that comprise the Madsen Mine, the South Austin structure is hosted within broad, kilometer-scale planar alteration and deformation corridors that have been repeatedly reactivated during gold mineralization and subsequent deformation and metamorphism.

At the deposit scale the Austin, South Austin, North Austin, and McVeigh Zones are locally folded and structurally dismembered by transposition and rotation into the penetrative S2 Foliation. In addition to this intense deformation overprint, the mineralized veins and alteration have been subjected to the relatively high temperatures of amphibolite facies metamorphism, which led to extensive recrystallization and growth of the skarn-like replacement mineral assemblage of diopside-amphibole-quartz-biotite.

All significant gold mineralization on the mine property is demonstrably early relative to the most significant, penetrative deformation (D2) and metamorphic events. The North Austin Zone displays ‘mine-style’ alteration and mineralization and consists of multiple mineralized domains defined over a strike length of 0.5km. Mineralization remains open at depth and along strike to the northeast.

In drill core, or at underground face exposures, gold-bearing zones at the Madsen Mine are best identified visually by fine (sub-millimetre) grains of free gold within strong alteration and veining. All high-grade intervals generally contain visible gold on drill core exteriors, although numerous examples exist of high-grade assays where visible gold was only identified within the interior (cut surface) of the core samples. Apart from the presence of free gold, pervasive silicification (locally accompanied by discrete quartz veining) and quartz-carbonate or diopside veining are the best indicators that a given interval is within a high-grade zone along/within the mineralized structure.

The current underground drilling program at the Madsen Mine is focused on further definition of near-term mining inventory, as well as growth of the current mineral resource. Drilling has been focused on the more continuous and higher-grade portions of the Austin, South Austin, North Austin and McVeigh Zones. This will continue to be the strategy through 2025.

QUALITY ASSURANCE/QUALITY CONTROL

Drilling completed underground at the Madsen Mine consists of BQ-sized diamond drill core for definition drill programs and oriented NQ-sized diamond drill core for exploration focused drilling. All drill holes are systematically logged, photographed, and sampled by a trained geologist at the Madsen Mine core processing facility. Minimum allowable sample length is 0.5m. Maximum allowable sample length is 1.5m. Control samples (certified standards and uncertified blanks), along duplicates, are inserted at a target 5% insertion rate. Results are assessed for accuracy, precision, and contamination on an ongoing basis. The BQ-sized drill core is whole core sampled. The NQ-sized drill core is then cut lengthwise utilizing a diamond blade core saw along a line pre-selected by the geologist. To reduce sampling bias, the same side of drill core is sampled consistently utilizing the orientation line as reference. For those samples containing visible gold (“VG”), a trained geologist supervises the cutting/bagging of those samples, and ensures the core saw blade is ‘cleaned’ with a dressing stone following the VG sample interval. Bagged samples are then sealed with zip ties and transported by Madsen Mine personnel directly to SGS Natural Resource’s Facility in Red Lake, Ontario for assay.

Samples are then prepped by SGS, which consists of drying at 105°C and crushing to 75% passing 2mm. A riffle splitter is then utilized to produce a 500g course reject for archive. The remainder of the sample is then pulverized to 85% passing 75 microns from which 50g is analyzed by fire assay and an atomic absorption spectroscopy (AAS) finish (SGS Code GO-FAA50V10). Samples returning gold values > 100 g/t Au are reanalyzed by fire assay with a gravimetric finish on a 50g sample (SGS Code GO_FAG50V). Samples with visible gold are also analyzed via metallic screen analysis (SGS code: GO_FAS50M). For multi-element analysis, samples are sent to SGS’s facility in Burnaby, British Columbia and analyzed via four-acid digest with an atomic emission spectroscopy (ICP-AES) finish for 33-element analysis on 0.25g sample pulps (SGS code: GE_ICP40Q12). SGS Natural Resources analytical laboratories operates under a Quality Management System that complies with ISO/IEC 17025.

The Madsen Mine deposit presently hosts a National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) Indicated resource of 1.65 million ounces (“Moz”) of gold grading 7.4 g/t Au within 6.9 Mt, and an Inferred resource of 0.37 Moz of gold grading 6.3 g/t Au within 1.8 Mt. Mineral resources are estimated at a cut-off grade of 3.38 g/t Au and a gold price of US$1,800/oz. Mineral resources as stated are inclusive of mineral reserves. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The Madsen Mine also contains Probable reserves of 478 thousand ounces (“koz”) of gold grading 8.16 g/t Au within 1.87 Mt. Mineral reserve estimates are based on a gold price of US$1,680/oz. Please refer to the technical report entitled “NI 43-101 Technical Report and Prefeasibility Study for the Madsen Mine, Ontario, Canada”, prepared by SRK Consulting (Canada) Inc. and dated January 7, 2025 (the “Madsen Report”). The Madsen Resource Estimate has an effective date of December 31, 2021, and excludes depletion of mining activity during the period from January 1, 2022, to the mine closure on October 24, 2022, as it has been deemed immaterial and not relevant for the purpose of the Madsen Report. A full copy of the Madsen Report is available on the Company’s website and on SEDAR+ at www.sedarplus.ca.
