Osisko Development Extends Gold Mineralization at Cariboo Project Beyond 700m Depth — Osisko Development Corp.

Event summary

Osisko Development's drilling at Cariboo Gold Project extended mineralization beyond 700m vertical depth, with intercepts including 13.19 g/t Au over 3.60m and 28.90 g/t Au over 0.50m.
The company completed 8,971 meters of new surface exploration drilling, with 65% targeting areas outside the current mineral resource footprint.
Drilling confirmed high-grade mineralization at depth, reinforcing potential for resource growth beyond the current deposit's average depth of 350m.
Osisko Development plans to change its name to Osisko Gold Group Inc. and update its trading symbols on TSXV and NYSE to 'OGG' effective July 20, 2026.

The big picture

Osisko Development's successful extension of high-grade gold mineralization at the Cariboo Project reinforces its strategic focus on deepening resource potential in established mining camps. The company's rebranding to Osisko Gold Group Inc. aligns with its ambition to transition from a development-stage entity to an intermediate gold producer, capitalizing on district-scale opportunities in North America.

What we're watching

Resource Growth Potential: The pace at which Osisko Development can convert these deep intercepts into measurable resource growth will determine the project's long-term viability.
Execution Risk: Whether the company can sustain high-grade intercepts at greater depths and translate them into economically viable reserves remains a key uncertainty.
Market Positioning: How Osisko Gold Group Inc. positions itself post-rebranding could influence investor perception and market valuation.
