San Antonio Project Mineral Resource
The MRE incorporates five deposits, Sapuchi, California, Golfo de Oro, High Life and Calvario, as part of what comprises 2.8 km of the 10.0 km within the Sapuchi-Cero Verde trend of the San Antonio Project (Figure 1). The deposits are in the indicated and inferred categories listed in Table 1 and a further breakdown by deposit and oxide zone are listed in the Tables 2 and 4. Grade sensitivity is presented in Table 3. Potential mining scenarios indicate a strip ratio of 1.0 to 6.7. The MRE was conducted by Talisker Exploration Services Inc., under the supervision of Servicios Geológicos IMEx, S.C and Micon International Limited.
The deposits are constrained within a geologic model of the hydrothermal breccia, the main mineralization control known to date. Additional drill targets remain underexplored on the property and new exploration drilling is recommended to verify historic data and potentially add new resource. Further infill and exploration drilling is recommended on the Project.
Operational Update
The San Antonio Project gold mineralization is characterized by hydrothermal breccia that forms an approximately 3,000 m long east-northeast trending mineralization corridor with the Luz del Cobre copper deposit at the east. The gold mineralization is associated with intense chlorite and carbonate alteration and is intrusion related with host sedimentary rocks. The breccia has been defined to a vertical depth of 500 m and at an average depth of 250 m. Drilling has occurred within the three major zones at Sapuchi, Golfo de Oro and California, over a combined strike length of 1 km of the 3 km breccia trend.
Since Osisko Development’s acquisition of the San Antonio Project in November 2020, the Company has successfully achieved the following operational milestones
Chris Lodder, President of Osisko Development commented, “The addition of this new resource further strengthens our portfolio for near term advancement and towards possible production. Osisko Development has made considerable progress at San Antonio in the past year with the construction of the leach pad, near term processing of the stockpile and completion of a drill program to generate this initial resource. The Company believes there is potential to add to the mineral resource through continued exploration and drilling on the property.”

The same notes for Tables 1 through 3 are applicable for Table 6. However, two separate pit scenarios were run: 1) A pit using just the oxide material and 2) a pit run using the oxide and transition material. These separate runs resulted in slightly different oxide and transition resources than those that resulted from using the ultimate pit where all three mineralization types were used.

Cautionary Statements Regarding Estimates of Mineral Resources
This news release uses the terms indicated and inferred mineral resources as a relative measure of the level of confidence in the resource estimate. Readers are cautioned that mineral resources are not mineral reserves and that the economic viability of resources that are not mineral reserves has not been demonstrated. The mineral resource estimate disclosed in this news release may be materially affected by geology, environmental, permitting, legal, title, socio-political, marketing or other relevant issues. The mineral resource estimate is classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum’s “CIM Definition Standards on Mineral Resources and Mineral Reserves” incorporated by reference into NI 43-101. Under NI 43-101, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies or economic studies except for preliminary economic assessments. Readers are cautioned not to assume that further work on the stated resources will lead to mineral reserves that can be mined economically.
Forward-looking Statements
Certain statements contained in this news release may be deemed "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 and "forward-looking information" within the meaning of applicable Canadian securities legislation. These forward‐looking statements, by their nature, require Osisko Development to make certain assumptions and necessarily involve known and unknown risks and uncertainties that could cause actual results to differ materially from those expressed or implied in these forward‐looking statements. Forward‐looking statements are not guarantees of performance. Words such as "may", "will", "would", "could", "expect", "believe", "plan", "anticipate", "intend", "estimate", "continue", or the negative or comparable terminology, as well as terms usually used in the future and the conditional, are intended to identify forward‐looking statements. Information contained in forward‐looking statements is based upon certain material assumptions that were applied in drawing a conclusion or making a forecast or projection, including management's perceptions of historical trends, current conditions and expected future developments, results of further exploration work to define and expand mineral resources, as well as other considerations that are believed to be appropriate in the circumstances, and any other information herein that is not a historical fact may be "forward looking information". Material assumptions also include, management's perceptions of historical trends, current conditions and expected future developments, results of further exploration work to define or expand any mineral resources, as well as other considerations that are believed to be appropriate in the circumstances. Osisko Development considers its assumptions to be reasonable based on information currently available, but cautions the reader that their assumptions regarding future events, many of which are beyond the control of Osisko Development, may ultimately prove to be incorrect since they are subject to risks and uncertainties that affect Osisko Development and its business. Such risks and uncertainties include, among others, risks relating to capital market conditions, the ability to continue current production, regulatory framework, the ability of exploration activities (including drill results) to accurately predict mineralization; errors in management's geological modelling; the ability of to complete further exploration activities, including drilling; property and stream interests in the Project; the ability of the Company to obtain required approvals; the results of exploration activities; risks relating to exploration, development and mining activities; the global economic climate; metal prices; dilution; environmental risks; and community and non-governmental actions and the responses of relevant governments to the COVID-19 outbreak and the effectiveness of such responses. Readers are urged to consult the disclosure provided under the heading "Risk Factors" in the Company's annual information form for the year ended December 31, 2021, as amended, which has been filed on SEDAR (www.sedar.com) under Osisko Development's issuer profile and on the SEC's EDGAR website (www.sec.gov), for further information regarding the risks and other factors applicable to the exploration results. Although the Company's believes the expectations conveyed by the forward-looking statements are reasonable based on information available at the date of preparation, no assurances can be given as to future results, levels of activity and achievements. The Company disclaims any obligation to update any forward-looking statements, whether as a result of new information, future events or results or otherwise, except as required by law. There can be no assurance that these forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements.
