West Red Lake Gold Mines Ltd. (TSX-V: WRLG) (OTCQX: WRLGF) is pleased to report drill results from its 100% owned Madsen Mine located in the Red Lake Mining District of Northwestern Ontario, Canada.

Will Robinson, Vice President of Exploration, commented, “We are pleased to announce another round of impressive assay results from our ongoing underground definition drill program at Madsen. The mineralized panels within the 904 and 955 complexes are holding together quite well with strong grades and continuity demonstrated across multiple areas. These results continue to build our confidence in the geological model and the potential for these areas to be integrated into the Madsen mine plan in 2027. Importantly, these complexes are located close to existing underground infrastructure, with the 904 complex representing non-remnant mineralization, meaning we are now advancing into fresh, previously unmined material, providing additional flexibility as we continue to define and advance mining inventory.”

The results from Austin 904 Complex reported herein were all drilled from the 13 and 14 Levels of the Madsen Mine at approximately 650 metre and 700m depth, respectively. These 904 results are in addition to those announced on July 7, 2026 which highlighted 10.22 grams per tonne gold over 13.35m, and on April 13, 2026 which highlighted 215.46 g/t Au over 5.35m, 50.34 g/t Au over 4.05m and 61.70 g/t Au over 3m, and on February 25, 2026 which highlighted 219.73 g/t Au over 4.8 m, 148.36 g/t Au over 3m and 133.13 g/t Au over 2.5m.

The results from the Austin 955 Complex were drilled from the 12 Level of the Madsen Mine at approximately 600m depth. These 955 results are in addition to those announced on July 7, 2026which highlighted 43.48 g/t Au over 3.85m and 53.87 g/t Au over 3.1m.

The Austin 904 represents a unique opportunity within the Madsen deposit, comprising an approximately 200m by 200m panel of intact gold mineralization that was not historically mined. This is rare for the Madsen deposit and places WRLG in a favorable position to have full access to the entire mineralized zone for mining which is expected to result in larger stopes and increased efficiency during design and extraction.

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

DISCUSSION

Like the other mineralized domains that comprise the Madsen Mine, the Austin structures are hosted within broad, kilometre-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 and South Austin Zones. It is anticipated that this will continue to be the strategy through 2026.

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, 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 ProjectsIndicated resource of 1.65 million ounces 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 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 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.
