Osisko Development Corp. filed a report highlighting its annual equity-based compensation awards to senior officers and non-executive employees. The company granted 1,104,400 stock options and 1,426,600 restricted share units under its omnibus equity incentive plan as part of its regular compensation cycle.
The options have an exercise price of C$4.51 per common share, expire on April 1, 2031, and vest in three equal annual installments. The RSUs will cliff vest on April 1, 2029, subject to time and performance conditions, aligning employee incentives with the company’s longer-term gold development objectives.
Osisko Development Corp. reported its fourth quarter and full-year 2025 update, highlighting a stronger balance sheet and progress at its flagship Cariboo Gold Project. As of December 31, 2025, the company held about $422.3 million in cash and cash equivalents and had approximately $145.8 million outstanding under the initial draw of its US$450 million senior secured project loan with Appian, earmarked for Cariboo’s development.
Q4 2025 revenue was $24.2 million from selling 3,970 ounces of gold produced through small-scale activities at the Tintic Project, generating $8.7 million in operating income. For 2025, Tintic small-scale processing and selective mining produced 6,240 gold ounces and $35.5 million in revenue.
The company bolstered funding with an $82.5 million private placement in October 2025, then a US$143.8 million ($196.2 million) common share prospectus offering and approximately $24.9 million of warrant proceeds in early 2026. Cariboo pre-construction work and a 13,000‑metre infill drilling program advanced, alongside a large 2026 drilling campaign targeting 160,000 metres across exploration and conversion drilling.
Osisko Development completed the sale of its San Antonio Gold Project to Axo Copper, receiving Axo shares and contingent payments tied to VAT refunds, a feasibility study and first gold pour. The company also faced a contractor fatality at Cariboo in January 2026, temporarily suspending site activities before resuming under a phased reopening approved by regulators. It added senior technical leadership, signed a project and construction management agreement for Cariboo, and was included in the VanEck Junior Gold Miners ETF (GDXJ).
Osisko Development Corp. announced that its shares will be included in the VanEck Junior Gold Miners ETF (GDXJ), effective at the close of markets on March 20, 2026, following the ETF’s semi-annual review. Management believes this widely followed gold mining ETF will enhance the company’s market visibility, trading liquidity, and broaden investor access.
The company links this inclusion to progress on its flagship, fully permitted, 100%-owned Cariboo Gold Project in central British Columbia, which it is working to advance and de-risk. Osisko Development positions itself as a North American gold developer focused on past-producing, district-scale mining camps, complemented by its Tintic Project in Utah.
Osisko Development Corp. reported that it has received approximately C$24.9 million in cash from the exercise of 5,625,031 common share purchase warrants held by funds advised by Appian Capital Advisory Limited. Each warrant had an exercise price of C$4.43 per common share.
The warrants were originally issued to Appian on July 21, 2025, in connection with a senior secured project loan credit facility totaling US$450 million. This facility supports development and construction of Osisko Development’s fully permitted, 100%-owned Cariboo Gold Project in central British Columbia, Canada.
Osisko Development Corp. has resumed planned site activities at its 100%-owned Cariboo Gold Project in British Columbia after a temporary suspension following an isolated tragic incident on January 22, 2026. Operations are restarting under a phased plan coordinated with regulatory authorities, with health and safety emphasized as the top priority.
The site now has over 250 personnel supporting pre-construction, early works and exploration drilling. About 2.1 km of underground development has been completed from the Cow Portal into the Lowhee Zone, though progress has been slower than planned in challenging ground around the Lowhee fault. An ongoing 13-km underground infill program continues, with 1.6 km remaining on the 1260 level and additional drilling on the 1290 level.
Six surface drill rigs are active, including deeper drilling below the current Cariboo Gold deposit and a new program at the nearby Proserpine target, with roughly 5,500 meters completed so far and assays pending. Key infrastructure is advancing, including the waste rock storage facility, sediment control pond, and mine site complex early works, while the camp expansion to 266 rooms is complete to align with expected peak construction manpower for this flagship project.
