Osisko Gold Drilling Confirms High-Grade Proserpine System Near Cariboo

• Osisko Gold Group identified a new mineralized system at the Proserpine target near its permitted Cariboo project in British Columbia.
• Initial drilling results highlight high-grade structures alongside broader zones indicating potential open-pit mining capabilities.
• Appian Capital Advisory provided a US$450 million senior secured loan to fund the development of the Cariboo Gold Project.
• Market analysts highlight Osisko Gold Royalties as a pure-play royalty company trading near net asset value with strong growth potential.

Osisko Gold Group has outlined a new mineralized system at its Proserpine target, located approximately seven kilometers from its permitted Cariboo Gold Project in British Columbia. Early drilling results indicate this system could support future open-pit mining alongside Cariboo’s planned underground operation. The discovery suggests significant potential to expand the company's resource base and extend the mine life of the broader district.

A standout intercept in hole PSP-26-004 cut 4.6 meters grading 95.93 grams per tonne of gold, including a 50-centimeter interval of 873 grams per tonne of gold. Another hole, PSP-26-001, returned 8.6 meters of 5.46 grams per tonne of gold and 14.5 meters of 2.17 grams per tonne of gold. These results confirm the presence of high-grade structures similar to the Cariboo deposit, alongside broader zones of lower-grade mineralization.

National Bank Financial analyst Don DeMarco noted that while the grades are exceptional, the scale of the system is the more critical factor. Mineralization remains open in all directions. The known footprint has expanded to roughly one kilometer along strike by 500 meters in width, with mineralization encountered from near surface to depths beyond 400 meters.

The company has resumed drilling with three rigs and plans an additional 26,500 meters to increase drill density at Proserpine Southeast. This exploration aims to test new targets at Proserpine Northwest and expand the mineralized footprint of the emerging system. The results provide a compelling basis for systematic follow-up drilling to define the scale of this new high-grade target.

How Does the Proserpine Discovery Affect Cariboo's Mine Life?

Osisko’s strategy focuses on growing its resource base beyond the Cariboo project, which currently hosts 1.61 million ounces of measured and indicated resources. The project is undergoing a feasibility study for a 10-year underground operation with a projected production of 1.89 million ounces of gold. Recent deep drilling at Cariboo has extended mineralization below 700 meters, reinforcing the project's long-term growth potential.

The Proserpine discovery supports the long-term viability of the Cariboo project by identifying potential open-pit mining opportunities adjacent to the permitted underground operation. This dual approach of underground and open-pit mining could significantly enhance the overall economics of the district. The siliceous sandstone unit was identified as a favorable host for mineralization, providing a geological model for future exploration.

What Is the Financing Structure for the Cariboo Project?

Appian Capital Advisory has provided a US$450 million senior secured project loan to Osisko Gold Group to fund the development of the Cariboo Gold Project. The facility includes a US$100 million initial draw, which enables Osisko to accelerate pre-construction activities and de-risk the project ahead of a final investment decision. An additional US$350 million is available in subsequent draws, subject to customary project milestones.

The initial draw will support infill drilling, detailed engineering, procurement, underground development, and operational readiness planning. This transaction allows Osisko to transition into an intermediate gold producer with a potential 10-year mine life delivering 1.89 million ounces. The financing structure diversifies Appian’s portfolio by providing exposure to gold, which typically offers uncorrelated returns compared to base metals.

How Is Osisko Gold Royalties Positioned in the Market?

Osisko Gold Royalties Ltd. has received a consensus recommendation of Moderate Buy from six equities research firms. The average 12-month price target among these analysts is C$63.20, significantly above the stock’s recent trading price of C$45.07. The company operates as a precious metals royalty and streaming company with a market cap of C$8.45 billion.

Investors identify Osisko Gold Royalties as a pure-play royalty company trading near net asset value, offering stable cash flows and organic growth of 10-12% annually. The company's model avoids the higher costs associated with being an operator, as royalties are paid regardless of cost inflation. A new CEO is reportedly cleaning up management conflicts and has successfully separated the company from Osisko Mining to become a pure royalty entity.

Osisko Gold Royalties reported quarterly earnings on August 5th, posting C$0.46 earnings per share on revenue of C$138.98 million. The company demonstrated a net margin of 82.42% and a return on equity of 19.91% for the quarter. The portfolio includes over 195 royalties, streams, and similar interests, anchored by a significant interest in Agnico Eagle Mines Limited's Canadian Malartic Complex.
