Osisko Development Reports Fourth Quarter 2021 and Year-End Results






Osisko Development Corp. (TSX-V:ODV) is pleased to report its financial and operating results for the three months ended December 31, 2021.


Fourth Quarter and Full Year 2021 Highlights

  • The Company began test mining and gold production from the Bonanza Ledge phase 2 mine and the San Antonio Stockpile heap leach mine.
  • The Company recently entered into an agreement to acquire the high grade Trixie gold mine and prolific East Tintic mining district in Utah. The Trixie project is anticipated to add meaningful low-cost production to Osisko Development with expected low capital intensity.
  • The Company advanced permitting on both its Cariboo and San Antonio Projects and expect to have required permits in hand to begin construction in late 2022 and early 2023.
  • The Company invested significant capital towards advancing the Cariboo and San Antonio gold projects by purchasing long lead items such as roadheaders, milling equipment, ore sorter and upgrading and or building new lodging, energy and access infrastructure.
  • The cash position for the Company as of December 31, 2021 was $33.4 million, and the market value of equity investments approximately CAD$87.4 million.
  • During the quarter the Company continued to operate in a safe and environmentally friendly manner while continuing to develop and uphold relationships with the community and Indigenous Nations. The Cariboo Gold Project is advancing through Environmental Assessment Process for a 4,750 tonne per day underground operation with a feasibility study targeted for completion in the first half of 2022. The receipt of the Environmental Assessment Certificate remains on schedule for the fall of 2022. The Cariboo Gold Project is the first project in the Province of British Columbia going through the new Environmental Assessment Process and has strong support from the Province and the Cariboo Region to develop and diversify the economy of the region affected by the pandemic.
  • Other important highlights in permitting are:
    • The Company successfully obtained approval for amendments to Mines Act Permits M-238 and M-198 allowing the expansion of the existing Bonanza Ledge II underground mine during the fourth quarter.
    • The Company received the Notice of Work permit to commence underground development and collect a 10,000 tonnes bulk sample for its Cariboo Gold Project to further increase confidence in the Project .The aim of the bulk sample is to further test the ore sorting technology and roadheader development.
  • The roadheader tested at the Bonanza Ledge site, which reached performance above expectation, was purchased and Osisko Development placed an order to secure two other roadheaders for the Cariboo Project. An ore sorter was purchased and will be commissioned to use in this bulk sample test. The portal construction for the bulk sample is completed and development has begun.
  • The Company purchased and installed two water treatment plants for the Bonanza Ledge site and the QR Mill for environmental requirements. The WTP at Bonanza Ledge was commissioned since June and the QR Mill will be commissioned in March 2022. Both installations will be re-used for the future Cariboo Gold Project and show the commitment of the Company toward improving environmental performance.
  • On the exploration and geology fronts, the Company drilled 152,500 meters in 2021 principally to support the feasibility study on the Cariboo Gold Project. The drill program was successful in defining robustness of geologic model, continuity of the high grade vein corridors as well as adding potential at depth and along strike. The drilling will be included in a mineral resource update to support the feasibility study in Q2 2022. Highlights of the drill campaign included 35.25 g/t Au over 11.0 meters, 7.35 g/t Au over 23.98 meters, and 281 g/t Au over 0.50 meter, 1,965 g/t Au over 0.50 meter at the Shaft Zone, 26.58 g/t Au over 5.05 meters and 7.87 g/t Au over 10.25 meters at the Valley Zone. In Mexico, the 27,900 meters were drilled in 2021 on the San Antonio Gold Project to support a maiden open pit mineral resource estimate to be completed in Q1 2022.   Complete drill results are yet to be released with the highlights to date of 3.93 g/t Au over 13.5 meters, 2.14 g/t Au over 21.65 meters, 1.52 g/t Au over 29.2 meters 1.02 g/t Au over 39.90 meters, 1.30 g/t Au over 22.0 meters in oxide and sulphide zones at Sapuchi, California and Golfo de Oro targets.

  • The Company incurred a net loss of $56.5 million during the quarter. The net loss is mostly due to the recognition of a non-cash impairment in the amount of $47.8 million, of which $42.0 million is related to an impairment on certain exploration and evaluation properties, including the James Bay properties and the Coulon zinc project in Canada. The remaining $5.8 million non-cash impairment is related to the revaluation of the stockpile inventory held at Sapuchi Minera.
  • The Company divested of certain investments from its portfolio generating gross proceeds of $20.6 million in 2022.


We are pleased by the progress achieved to date at both Cariboo and San Antonio. The ongoing work at Cariboo has advanced our Environmental Assessment and Feasibility Study bringing us closer to our major milestones. The exploration model and metallurgical test work at Cariboo have continued to build value as we finish this work and better understand this project and the upside. It is a rare exceptional opportunity in Canada. The San Antonio project has more than fulfilled our original expectations and we continue to see near surface exploration results and upside. We have achieved first production and look forward to building on that success.


The Tintic opportunity is one of the most exceptional high grade opportunities we have seen and we look forward to closing this acquisition and doing what Osisko does best and unlock the geological potential of this historic camp. I want to thank all the Shareholders, Stakeholders and employees for their support throughout a very challenging period for everyone. It is truly appreciated by all of us.” Commented Sean Roosen, Chair and Chief Executive Officer of Osisko Development.


Financing and Future Projects

  • On January 25th, 2022, the Company announced that it had entered into binding agreements to acquire 100% ownership of the ultra high grade, producing and permitted Trixie Mine, as well as a land package covering over 17,000 acres and hosting 23 past-producing mines in Central Utah’s historic Tintic Mining District. Closing of the Tintic Transaction is expected to occur in Q2 2022.
  • Concurrently with, or shortly following the Tintic Acquisition, the Company entered into the financing arrangements set out below:
    • A non-binding metals stream term sheet with Osisko Gold Royalties which, on closing of the Tintic Acquisition, would provide the Company with upfront cash proceeds of at least US$20 million and up to US$40 million;
    • A non-brokered private placement for aggregate gross proceeds to the Company of approximately US$110.3 million, which will be held in escrow until certain conditions are met, including the Company listing its common shares on the New York Stock Exchange; and
