WEST RED LAKE GOLD INTERCEPTS 44.17 G/T AU OVER 1.3M AND 20.63 G/T AU OVER 0.5M AT UPPER 8 TARGET - MADSEN PROPERTY
West Red Lake Gold Mines Ltd. has released the initial drill results from the Upper 8 target from its 100-per-cent-owned Madsen property, located in the Red Lake gold district of Northwestern Ontario, Canada.
The drill results featured in this news release are focused on the Upper 8 target, which is a shallower geologic analog to the well-known high-grade 8 zone. The Upper 8 target is hosted within the same lithologic unit (Russet Lake ultramafic) approximately 750 metres (m) up-plunge from the main 8 zone deposit. Its location in ultramafic rocks, its style of mineralization and its exceptionally high grades make the 8 zone geologically unique from the main Madsen deposit. The 8 zone currently contains an indicated mineral resource of 87,700 ounces (oz) grading 18 grams per tonne (g/t) gold (Au), with an additional inferred resource of 18,200 oz grading 14.6 g/t Au.
These are the first drill results announced from a continuing 10,000 m surface exploration drilling program designed to test a number of high-priority targets across the Madsen property. Details and target descriptions for this program were outlined in a previous news release dated Aug. 10, 2024.
Upper 8 highlights:
- Hole
WRL24-002 intersected 4.1 m at 14.20 g/t Au, from 354.8 m to 358.9 m, including 1.3 m at 44.17 g/t Au, from 357.0 m to 358.3 m.
-
Hole
WRL24-003 intersected 1.85 m at 6.33 g/t Au, from 332.45 m to 334.30 m, including 0.5 m at 20.63 g/t Au, from 333.8 m to 334.3 m.
Will Robinson, vice-president of exploration, stated: "The initial results from Upper 8 drilling are quite encouraging and not only demonstrate proof of concept for our regional targeting model, but also reinforce our thesis that there is very real potential for discovery of another 8 zone type deposit on our highly prospective Madsen property. The relatively shallow position of Upper 8 allows for us to drill this target effectively from surface with a high degree of accuracy. With two out of three of the initial holes drilled at Upper 8 returning high-grade gold mineralization where projected, we are planning to add a second drill in the coming weeks dedicated to drilling at Upper 8. The team is very excited to return to this area to continue defining and growing this shallower 8 zone analog."
Discussion
Drilling on the Upper 8 target is designed to test the projected, near-surface extension of the mineralized shear corridor that hosts the highly prospective 8 zone. The Upper 8 target horizon was intercepted in only a few historic drill holes, which encountered a zone of strong shearing, alteration and quartz veining equivalent to 8 zone style mineralization.
Recent drilling on the Upper 8 target by the company has shown that gold mineralization is similar in geological setting and style as the deeper 8 zone deposit. Elevated gold at Upper 8 is shown to occur within deformed and recrystalized blue-grey quartz and quartz-sulphide veinlets. These veinlets are hosted within shear domains, which are easily recognizable by their locally intense deformation fabrics, and the presence of silica, biotite, potassium feldspar and amphibole alteration.
The Upper 8 shear domain is hosted within the Russet Lake ultramafic, which also hosts the 8 zone deposit and the angle of shear emplacement of Upper 8 is sympathetic to the structural orientation observed at 8 zone. Recognition that the gold mineralization at the Upper 8 target comprises transposed quartz veinlets within a definable and recognizable shear corridor provides excellent opportunity for additional drilling and expansion potential.
Quality assurance/quality control
Exploration drilling completed on surface at the Madsen mine consists of oriented NQ-sized diamond drill core. 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 0.5 m. Maximum allowable sample length is 1.5 m. Control samples (certified standards and uncertified blanks), along duplicates, are inserted at a target insertion rate of 5 per cent. Results are assessed for accuracy, precision and contamination on a continuing 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 preselected 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 Resources' facility in Red Lake, Ont., for assay.
Samples are then prepped by SGS, which consists of drying at 105 C and crushing to 75 per cent passing two millimetres. A riffle splitter is then utilized to produce a 500-gram course reject for archive. The remainder of the sample is then pulverized to 85 per cent passing 75 microns from which 50 g is analyzed by fire assay and an atomic absorption spectroscopy (AAS) finish (SGS code GO-FAA50V10). Samples returning gold values more than 10 g/t Au are reanalyzed by fire assay with a gravimetric finish on a 50-gram sample (SGS code GO-FAG50V). Samples with visible gold or returning gold values more than 30 g/t Au are also analyzed via metallic screen analysis (SGS code GO-FAS50M). For multielement analysis, samples are sent to SGS's facility in Burnaby, B.C., and analyzed via four-acid digest with an atomic emission spectroscopy (ICP-AES) finish for 33-element analysis on 0.25-gram 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, indicated resource of 1.65 million ounces of gold grading 7.4 g/t Au and an inferred resource of 370,000 ounces 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 $1,800 (U.S.) per 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, and amended April 24, 2024. The Madsen resource estimate has an effective date of Dec. 31, 2021, and excludes depletion of mining activity during the period from Jan. 1, 2022, to the mine closure on Oct. 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+.
