SAFEVANO: Osisko Gold Confirms High-Grade Mineralization At Proserpine Target

• Osisko Gold Group completed 6,463 meters of drilling at the Proserpine target, confirming a new high-grade gold mineralized system with open-pit mining potential.
• Appian Capital Advisory provided a $450 million senior secured project loan to fund the construction of the permitted Cariboo Gold Project.
• The company completed its name change to Osisko Gold Group Inc. to better align with its strategic focus on gold assets.
• Support and Benefits Agreements with local municipalities secure community backing for regional exploration activities.

Osisko Gold Group Inc. announced initial diamond drilling results from 14 holes totaling 6,463 meters at the Proserpine regional greenfield target. The target is located approximately seven kilometers southeast of the company’s permitted Cariboo Gold Project in British Columbia. The program confirmed an emerging gold mineralized system characterized by high-grade structures similar to the Cariboo deposit.

Broader zones of lower-grade mineralization were also identified, suggesting potential for bulk open-pit mining methods. Management highlighted that less than half of the four-kilometer prospective strike length at Proserpine has been tested. All holes reached target depths intersecting mineralization, prompting the resumption of a 26,500-meter drilling campaign.

Key intercepts included 95.93 grams per tonne of gold over 4.60 meters and 5.46 grams per tonne of gold over 8.60 meters. Mineralization was encountered from near-surface to depths exceeding 400 meters, expanding the known footprint to approximately 1.0 kilometer by 0.5 kilometer. Drilling also intersected significant intervals of siliceous sandstone, identified as a favorable host rock for mineralization.

The company plans to add 26,500 meters of drilling to increase density at Proserpine Southeast. First-pass drilling will initiate at Proserpine Northwest, seeking to define a significant new resource base. This exploration aims to complement the permitted Cariboo Gold Project, which hosts probable reserves of 2.071 million ounces of contained gold.

How Does The Financing Structure Support Project Development?

Appian Capital Advisory entered into a credit agreement for a senior secured project loan facility of up to $450 million. The proceeds are designated for the development and construction of Osisko’s flagship Cariboo Gold Project. The facility includes a $100 million initial draw to de-risk the project ahead of a final investment decision.

The remaining $350 million is available for subsequent draws contingent on customary project milestones. The initial draw will support infill drilling, detailed engineering, and operational readiness planning. This transaction diversifies Appian’s portfolio by adding gold, an asset class with typically uncorrelated return profiles.

According to the 2025 Feasibility Study, the Cariboo Gold Project has the potential to produce 1.89 million ounces of gold over a 10-year mine life. Osisko Gold Group is a North American gold development company focused on past-producing mining camps in mining-friendly jurisdictions. The company’s primary objective is to transition into an intermediate gold producer.

What Strategic Changes Are Supporting Operational Growth?

Osisko Development Corp. completed its name change to Osisko Gold Group Inc. to better align with its focus on gold assets. The rebranding reflects the company's strategic focus on its gold assets, particularly the Cariboo Gold Project in British Columbia. The change applies to its listings on the NYSE and TSXV.

Osisko Gold Group Inc. announced that it has entered into a Support and Benefits Agreement with the District of Wells. This agreement is designed to secure local community support and outline benefits for the region. The partnership aims to align the interests of the company with the local municipality.

Osisko Gold Group reported the completion of its infill drill program at the Lowhee Zone of the Cariboo Gold Project. The final results from this program support the continued use of existing geological and mine-planning assumptions. This validation is critical for maintaining the accuracy of resource estimates and operational planning for the project.

Osisko Development Corp. reported results from 8,971 meters of new surface exploration drilling. The drilling extended known gold mineralization beyond 700 meters vertical depth in previously untested areas. Notable intercepts included 13.19 grams per tonne of gold over 3.60 meters at 596 meters vertical depth.

Osisko Gold Royalties Ltd. is undergoing a significant strategic restructuring to become a pure-play royalty company. The company has successfully separated itself from Osisko Mining through a secondary offering. This move addresses historical governance issues and management conflicts.

Analysts view the company as undervalued relative to its Net Asset Value, citing a strong development pipeline. The company benefits from a diversified portfolio of precious metal royalties across North American mines. Financial stability is supported by significantly reduced long-term debt and improved balance sheet health.

The strategic pivot aims to reduce management conflicts and stabilize cash flows for investors. Osisko Gold Royalties is positioned for organic growth estimated at 10 to 12 percent annually. The combination of capital appreciation potential and stable cash flows makes the model attractive for long-term portfolios.
