VANCOUVER, British Columbia, Aug. 06, 2025 (GLOBE NEWSWIRE) — West Red Lake Gold Mines Ltd.
(“West Red Lake Gold” or “WRLG” or the “Company”) (TSXV: WRLG)
(OTCQB: WRLGF) is pleased to provide an update on ramp-up activities at the Madsen Mine in Red Lake, Ontario.

“July was a good month for Madsen and our mine operations team, and we continue to track to plan on our ramp up,” said Shane Williams, President and CEO. “Mine ramp-up is about adding equipment, developing access to high-priority mining areas, and increasing operational efficiency until the mine consistently produces the targeted daily tonnage at the targeted grade. During July, all these ramp-up elements played a positive role at Madsen. The mill achieved an average of 94% recovery over the month while processing 500-800 tonnes per day. Additionally, material mined from sill access development carried gold grades well above expectation on several occasions. Collectively, this enabled Madsen to pour 3,800 ounces for the month of July.”

In July the Madsen mine operations team completed sill development and mining in eight (8) areas spread across McVeigh, South Austin, and Austin. Sill development was a priority in the month, to enable a focus on stope mining in August. Mill feed in July was therefore a mix of mined material and low-grade stockpiles. Mined material carried an average grade of 8.9 grams per tonne gold. Since sill mining is less efficient than stope mining in terms of producing tonnage, mined tonnage was combined with low grade stockpile to produce an average grade of around 5g/t going into the mill.

Three (3) gold pours took place over the month to produce 3,800 ounces of gold. Of that, 3,595 ounces were sold at an average price of US$3,320 per oz. to generate US$12 million ($C16.4M) in revenues.

Continued Strong Stope Reconciliation

Article content

Tightening drill hole spacing from 20 metres to 7 metres (average distances) to inform an in-house resource model of high accuracy and resolution prior to final stope design is fundamental to West Red Lake Gold’s approach to mining at Madsen. The mineralized system at Madsen has been altered and deformed, resulting in gold mineralization that is high grade and pervasive but not always continuous. Tight definition drilling to inform an accurate geologic model is essential for better understanding grade continuity in the deposit.

The effectiveness of this approach was apparent in the close reconciliation between expected and actual grades and tonnes in the bulk sample (see May 7 news release). Figure 2 below shows a similar degree of reconciliation for a recently mined stope in McVeigh. Expected or modeled grade is shown in blue. Average grade mined is shown in red. Number of muck samples taken is shown in orange.

July Sill Grade Performance

Article content

Stope areas at Madsen are drill tested to 7-metre spacing. Sills, which are the access levels developed above and below stopes to create access to mine, are not always drilled to 7-metre spacing because of stope and drill bay geometry. In addition, chip sampling along sills adds data to the model before stopes are mined. As a result of these two factors, sills are expected to return higher grade variability versus the model than stopes.

Such variability is shown in Figure 3 below, which is a summary generated weekly at site by the Production Geology team that shows the number of sill development rounds that were expected to generate high grade (red), low grade (green), and waste (blue) material and the actual grades achieved for each kind of material.
