Mineral Resource Estimate notes:

1. The independent and qualified persons for the mineral resource estimates, as defined by NI 43-101, are Christine Beausoleil, P.Geo., and Carl Pelletier, P.Geo. (InnovExplo Inc.). The effective date of the mineral resource estimate is October 5, 2020.
2. These mineral resources are not mineral reserves as they do not have demonstrated economic viability.
3. The mineral resource estimate follows CIM Definition Standards.
4. A total of 334 vein zones were modelled for the Cow Mountain (Cow and Valley), Island Mountain (Shaft and Mosquito), Barkerville Mountain (BC Vein, KL, and Lowhee) deposits and one (1) gold zone for Bonanza Ledge. A minimum true thickness of 2.0 m was applied, using the grade of the adjacent material when assayed or a value of zero when not assayed.
5. The estimate is reported for a potential underground scenario at cut-off grade of 2.1 g/t Au. The cut-off grades were calculated using a gold price of US$1,350 per ounce.

The vein corridors comprising the Cariboo resource estimate are modelled to an average depth of 350 meters, exploration drilling has intersected mineralization at depths below 700 meters from surface. The Resulting Issuer will continue with the systematic exploration to further define and expand the known zones and develop greenfield targets on the remaining land package. The Resulting Issuer intends to drill from underground infrastructure once permitting and construction of an exploration drift is complete. The robust 3D litho-structural model that defines the controls of mineralization allows the exploration team to define additional mineral resource much more efficiently, with a high hit rate (80% of the drill holes intersect potentially economic mineralization), lowering the cost per discoverable ounce. This model can be applied to the remaining 65 kilometers of strike.

In accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”), an updated technical report for the Cariboo will be filed on SEDAR (www.sedar.com) under Osisko Royalties’ issuer profile and, in due course, the Resulting Issuer’s issuer profile.

The Company cautions that the decision to undertake test mining at Bonanza Ledge II has been taken without the benefit of a feasibility study of mineral reserves, demonstrating economic and technical viability, and, as a result there may be increased uncertainty of achieving any particular level of recovery of material or the cost of such recovery. The Company cautions that historically, such projects have a much higher risk of economic and technical failure. There is no guarantee that production will continue as anticipated or at all or that anticipated production  costs will be achieved.  The failure to continue production would have a material adverse impact on the Company’s ability to generate revenue and cash flow to fund operations.  Failure to achieve the anticipated production costs would have a material adverse impact on the Company’s cash flow and potential profitability.  In continuing current operations at Bonanza Ledge II, as contemplated, the Company will not be basing its decision to continue such operations on a feasibility study of mineral reserves demonstrating economic and technical viability.
