West Red Lake Intersects up to 135 g/t Gold in New Drilling at Madsen Mine

West Red Lake Gold Mines Ltd. (TSXV: WRLG) (OTCQB: WRLGF) reported drill results from its 100% owned Madsen Mine located in the Red Lake Gold District of Northwestern Ontario, Canada.

The drill results featured in this news release were focused on the high-grade South Austin Zone, which currently contains an Indicated mineral resource of 474,600 ounces (“oz”) grading 8.7 grams per tonne (“g/t”) gold (“Au”), with an additional Inferred resource of 31,800 oz grading 8.7 g/t Au.

The purpose of this drilling was definition within South Austin to continue building an inventory of high-confidence ounces for eventual restart of the Madsen mill. Notably, visible gold (“VG”) was observed in holes MM24D-12-4640-008 and -012 (Figure 1). Based on these observations, additional holes were added to the drill station to further define these high-grade zones up and down plunge.

The team has been making great progress de-risking the Madsen deposit with definition drilling as we continue to build up an inventory of high-grade and high-confidence ounces that will prove invaluable during the initial ramping up of mine production. The Mine Operations team is working in tandem with Geology to ensure the underground drills get to the highest priority areas of the deposit. The excellent results highlighted in this release are indicative of the upside that still exists at Madsen even within the current life-of-mine resource inventory.Shane Williams, President & CEO, West Red Lake Mines Ltd.

Plan maps and section for the South Austin drilling outlined in this release are provided in Figures 2 through 6.

Since underground drilling resumed in early January 2024 the Company has completed 1,996m of Expansion drilling and 2,716m of Definition drilling. In total, 56 diamond drill holes for 4,367m have been completed so far in 2024 at the Madsen Mine. Fire and metallic screen assays have been returned for 56 out of 56 holes completed, with 1 Expansion hole currently drilling.

Accessed through the Madsen Mine West Portal, the South Austin Zone sits south in the hanging wall of the main Austin Zone. Like the other mineralized domains in 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, and North Austin Zones. This will continue to be the strategy moving into 2024.

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 (“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. Mineral resources that are not mineral reserves do not have demonstrated economic viability. 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. A full copy of the SRK report is available on the Company’s website and on SEDAR+ at www.sedarplus.ca.
