Osisko Development Corp.'s SEC filings document its Form 6-K reporting as a foreign issuer that files on Form 40-F, including press-release exhibits and notices for annual and special meetings of common shareholders. The records cover the company's North American gold-development business, led by the Cariboo Gold Project in British Columbia and complemented by the Tintic Project in Utah.
Recent filings disclose operating and financial results, Cariboo construction and pre-construction activity, Lowhee Zone drilling, Tintic small-scale mining activity, completed financings, warrant exercises, equity incentive awards and governance appointments. Meeting notices also identify common shares as the voting security class and record notice-and-access and beneficial-owner delivery arrangements.
Osisko Development Corp. reported its Q1 2026 results, highlighting a strong cash position and ongoing build-out of its flagship Cariboo Gold Project. As of March 31, 2026, the company held about $594.3 million in cash and cash equivalents and had $153.2 million outstanding under its US$450 million project loan facility with Appian-advised funds. It generated $2.2 million of revenue and a narrower operating loss of $9.7 million, largely from selling 270 ounces of gold from small-scale activities at the Tintic Project. The company raised additional funding by issuing 40,607,650 common shares for US$143.8 million in gross proceeds and receiving $36.5 million from warrant exercises, supporting Cariboo development and exploration.
At Cariboo, Osisko completed a 13,684-metre infill drill program at the Lowhee Zone, advanced underground development (about 2.1 km completed), progressed water treatment and surface infrastructure, and expanded camp capacity to 266 rooms. It also completed the sale of the San Antonio Gold Project, was added to the VanEck Junior Gold Miners ETF (GDXJ), and continued small-scale test mining at Tintic. The company emphasizes significant financing and development risks, noting it has no commercial production-stage mines and depends on access to equity and debt markets to advance its projects.
Osisko Development Corp. reported Q1 2026 net income of $60.2 million, reversing a prior-year loss, mainly from a $32.9 million gain on warrant liability revaluation and a $28.0 million gain from discontinued operations.
Core operations remain small, with revenues of $2.2 million and an operating loss of $9.7 million. Cash and cash equivalents rose to $594.3 million, driven by a February bought-deal equity financing of $196.3 million and warrant and option exercises.
Despite working capital of $355.1 million and adjusted working capital of $543.6 million, management states that current liquidity and available credit facilities will not cover obligations and planned spending through March 2027, and highlights material uncertainties that may cast substantial doubt on the company’s ability to continue as a going concern.
Osisko Development Corp. has appointed Ms. Sarah MacDonald as Vice President, Construction Contracting and Commercial, effective immediately. The company notes that her role is important as it continues to advance its flagship Cariboo Gold Project in British Columbia.
MacDonald brings more than 18 years of experience in legal, contract, and corporate affairs, most recently as General Counsel at Dumas Contracting Ltd., supporting underground mining operations across North America. She has led initiatives in enterprise risk management, corporate governance, and sustainability reporting, and previously practiced corporate and commercial law for over a decade.
The company reiterates its strategy as a North American gold development business focused on past-producing mining camps, aiming to become an intermediate gold producer through development of the Cariboo Gold Project and its Tintic Project in Utah.
Osisko Development Corp. has set key dates for its upcoming Annual and Special Meeting of Security Holders. The meeting is scheduled for June 23, 2026, with a record date of May 11, 2026 for notice, voting, and beneficial ownership determination.
Holders of common shares are entitled to receive notice of the meeting and to vote. The company will use Notice-and-Access for both registered shareholders and beneficial holders, and proxy-related materials will be sent directly to Non-Objecting Beneficial Owners, with the issuer paying for delivery to Objecting Beneficial Owners.
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. filed its Annual Report on Form 40-F for the fiscal year ended December 31, 2025, reporting 255,069,516 common shares outstanding as of the close of the period. The filing states common shares trade as ODV on the New York Stock Exchange and that listed warrants (ODVWZ) are exercisable at $10.70 per share. Management concluded that internal control over financial reporting was effective as of year-end and the company qualified as an emerging growth company. The report incorporates the AIF, audited consolidated financial statements, MD&A, officer certifications, auditor consents, and a mine safety disclosure as exhibits.
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.
