XST (KGeN) Confirms High-Grade Gold Discovery at Proserpine Target

• Osisko Gold Group identified new high-grade gold mineralized system at the Proserpine target in British Columbia.
• The discovery features structures suitable for open-pit mining adjacent to the permitted Cariboo project.
• Key intercepts include 95.93 grams per tonne gold over 4.6 meters and exceptional high-grade intervals.
• The company plans 26,500 meters of additional drilling to test the expanding mineralized footprint.

Osisko Gold Group has outlined a new mineralized system at its Proserpine target, located approximately 7 kilometers from its permitted Cariboo Gold Project in British Columbia. Initial diamond drilling results confirm the presence of high-grade gold structures that exhibit similarities to the Cariboo deposit. This discovery also reveals broader zones of lower-grade mineralization, suggesting potential for open-pit, bulk mining methods alongside the planned underground operation at Cariboo.

Standout drill intercepts have drawn significant attention from analysts and investors. Hole PSP-26-004 intersected 95.93 grams per tonne gold over 4.60 meters, including a high-grade interval of 873 grams per tonne gold over 0.50 meters. Another significant intercept in hole PSP-26-001 returned 5.46 grams per tonne gold over 8.60 meters. These results provide compelling evidence of a significant new gold mineralized system of scale.

Drilling has expanded the known mineralized footprint at Proserpine to roughly 1.0 kilometer along strike by 0.5 kilometer in width. Mineralization remains open in all directions, extending from near surface to depths exceeding 400 meters. The program completed 6,463 meters in 14 holes, with all holes that reached their intended target depths encountering mineralization. This comprehensive success rate underscores the geological potential of the target area.

National Bank Financial analyst Don DeMarco noted that while the exceptional grades are noteworthy, the scale of the target is the more critical factor for investors. The drilling has defined mineralization over only a small portion of a much larger target that remains open in all directions. Proserpine is one of several regional targets being tested to identify additional deposits and support resource growth at Cariboo.

Following a brief, planned seasonal hiatus, Osisko has resumed drilling with three active rigs. The company plans an additional 26,500 meters of drilling to increase drill density at Proserpine Southeast and initiate first-pass drilling at previously untargeted areas at Proserpine Northwest. This exploration success has bolstered investor confidence, with the stock rising 12.2% following the announcement.

The Cariboo project remains Osisko’s main development, featuring a permitted underground mine and processing complex. A 2025 feasibility study outlines a scalable operation producing 1.89 million ounces of gold over ten years. The project has an after-tax net present value of $943 million based on a gold price of $2,400 per ounce. Recent deep drilling at Cariboo has also extended mineralization below 700 meters, reinforcing long-term growth potential.

Osisko Gold is a Canadian gold mining and exploration company listed on the NYSE and TSXV. The company’s primary focus is advancing its 100%-owned, permitted Cariboo Gold Project. Operating within the broader Cariboo Gold Project property, Osisko Gold is actively pursuing regional greenfield targets to expand its resource base.

Analyst sentiment remains cautiously optimistic, with a recent rating of Buy and a price target of C$10.00. However, TipRanks’ AI Analyst Spark rates the stock as Neutral due to persistent losses and heavy cash burn. Despite these financial pressures, the company maintains a strong balance sheet and a diversified asset base. The latest exploration results at Proserpine highlight the potential for resource growth and mine life extension.

What Are the Implications for Bulk Mining Methods?

The identification of broader lower-grade zones at Proserpine indicates potential for open-pit mining methods. This complements the high-grade underground targets at the Cariboo deposit. The mineralization style at Proserpine mirrors that of Cariboo, featuring high-grade gold associated with quartz-pyrite veins. President Chris Lodder expressed encouragement regarding the potential for a significant new gold mineralized system of scale.

The intersection of siliceous sandstone units, believed to be a favorable host for mineralization, was also confirmed. This geological confirmation provides a solid basis for systematic follow-up drilling. Diamond drilling at Proserpine has resumed with three active drill rigs to increase drillhole density. Additional drill rigs may be mobilized as warranted to expand the mineralized footprint.

How Does This Discovery Affect Osisko’s Strategic Outlook?

Proserpine represents a strategic addition to Osisko’s portfolio of regional targets. The discovery supports the company’s strategy to expand its resource base and extend mine life. The known footprint has expanded significantly, with mineralization encountered across all 14 target holes. This provides a compelling basis for systematic follow-up drilling and resource definition.

Osisko Gold Group is actively pursuing these regional greenfield targets to identify additional deposits. The exploration success at Proserpine validates the geologic model for further exploration. The company plans to test a larger 6.0 km by 1.0 km anomaly with the additional drilling. This systematic approach aims to define the full extent of the mineralized system.
