West Red Lake Gold Mines Ltd (TSXV: WRLG) (OTCQB: WRLGF) Reported additional drill results from its 100% owned Madsen Mine located in the prolific Red Lake Gold District of Northwestern Ontario, Canada.
This first round of drill results from the Madsen Mine were all drilled from underground on the North Austin Zone, which represents a new area of high-grade mineralization extending the current Madsen resource to the northeast.
The WRLG team believes these intercepts are indicative of the exceptional resource growth potential that still exists at the Madsen Mine asset. The North Austin Zone sits adjacent to existing underground development marking it as a high caliber target that could potentially be developed early during future mine restart and production.
The North Austin Zone remains open down-dip and along strike to the northeast and will continue to be a priority expansion target as underground drilling continues.

Plan maps and section for the North Austin drilling outlined in this release are provided in Figures 1 through 3.
Since underground drilling commenced near the end of September 2023 the Company has completed 848m of Exploration drilling and 3,369m of Definition drilling.
In total, 70 diamond drill holes for 4,217m have been completed so far in 2023 at the Madsen Mine. Fire and metallic screen assays have been returned for 65 out of 70 holes completed, with 5 holes pending assays and QAQC.

Accessed through the Madsen Mine East Portal, the North Austin Zone sits northeast in the footwall of the main Austin Zone. Like the main Austin and South Austin Structures, the North Austin domain 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-likereplacement 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 theAustin, South Austin, and North Austin Zones. This will continue to be the strategy moving into 2024.

WEDGE DEPOSIT – DRILLING RESULTS
The Company completed a total of 11 diamond drill holes for 2,995.5m from surface at the Wedge deposit between September 8 and October 3, 2023. The objective of this drill program was expanding and upgrading the existing mineral resources at Wedge, which currently contain an Indicated mineral resource of 56,100 oz grading 5.6 g/t Au, with an additional Inferred resource of 78,700 oz grading 5.7 g/t Au. The mineralized zones encountered at Wedge confirm the geologic model and help to extend high-grade chutes within the existing Mineral Resource.

• Hole WDG-23-001 Intersected 1.35m @ 10.10 g/t Au, from 189.5m to 190.85m

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 SGSNatural 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 50gsample (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 (“NI 43-101”) Indicated resource of 1.65 million ounces (“Moz”) of gold grading 7.4 g/t Au and an Inferred resource of 0.37 Moz of gold grading 6.3 g/t Au. Mineral resources are estimated at a cut-off grade of 3.38 g/t Au and a gold price of US1,800/oz. Please refer to the technical report entitled “Independent NI 43-101 Technical Report and Updated Mineral Resource Estimate for the PureGold Mine, Canada”, prepared by SRK Consulting (Canada) Inc. and dated June 16, 2023. 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 updated report.
