OSISKO EXPANSION DRILLING ADDS NEW HIGH GRADE AT LYNX
Osisko Mining Inc. has provided new analytical results from the continuing drill program at its 100-per-cent-owned Windfall gold project located in the Abitibi greenstone belt, Urban township, Eeyou Istchee James Bay, Quebec.
Drilling is currently focused on the Lynx deposit. Significant new analytical results presented below include 66 intercepts in 22 drill holes (5 from surface, 17 from underground) and 21 wedges. The intercepts are located outside the February 2021 mineral resource estimate ("MRE") (see Osisko news release dated February 17, 2021) and either expand resource wireframes or are located in a defined zone or corridor but do not yet correlate to a specific wireframe.
Osisko Chief Executive Officer John Burzynski commented: "Today's expansion results in Lynx and Triple Lynx continue to confirm the growth potential of these zones. The higher-grade intercept in OSK-W-20-2381-W1 extends Lynx 90 metres from the nearest MRE block and WST-20-0602 extends Triple Lynx 100 metres from the nearest MRE block".
Selected high-grade intercepts include: 177 g/t Au over 3.0 metres and 66.6 g/t Au over 2.0 metres in OSK-W-20-2381-W1; 43.4 g/t Au over 5.3 metres in WST-20-0602; 56.4 g/t Au over 3.2 metres in WST-20-0603; 52.1 g/t Au over 3.4 metres in WST-20-0611; 70.2 g/t Au over 2.2 metres in OSK-W-20-2313-W7; 57.2 g/t Au over 2.1 metres in OSK-W-20-2391; and 25.1 g/t Au over 4.8 metres in OSK-W-20-2252-W8.

Lynx Zone
Mineralization occurs as grey to translucent quartz-carbonate-pyrite-tourmaline veins and pyrite replacement zones and stockworks. Vein-type mineralization is associated with haloes of pervasive sericite-pyrite plus or minus silica alteration and contain sulphides (predominantly pyrite with minor amounts of chalcopyrite, sphalerite, galena, arsenopyrite, and pyrrhotite) and local visible gold. Replacement mineralization is associated with strong pervasive silica-sericite-ankerite plus or minus tourmaline alteration and contains disseminated pyrite from trace to 80% with local visible gold. Pyrite stockworks can form envelopes that reach several tens of metres thick. Fuchsite alteration is common and is spatially constrained to near the gabbros. Mineralization occurs at or near geological contacts between felsic porphyritic or fragmental intrusions and the host rhyolites or gabbros and locally can be hosted along the gabbro-rhyolite contact.
Qualified Person
The scientific and technical content of this news release has been reviewed, prepared and approved by Mr. Louis Grenier, M.Sc.A., P.Geo. (OGQ 800), Project Manager of Osisko's Windfall Lake gold project, who is a "qualified person" as defined by National Instrument 43-101 {䮧 –} Standards of Disclosure for Mineral Projects ("NI 43-101").
Quality Control and Reporting Protocols
True width determination is estimated at 55-80% of the reported core length interval for the zone. Assays are uncut except where indicated. Intercepts occur within geological confines of major zones but have not been correlated to individual vein domains at this time. Reported intervals include minimum weighted averages of 3.0 g/t Au diluted over core lengths of at least 2.0 metres. NQ core assays were obtained by either 1-kilogram screen fire assay or standard 50-gram fire-assaying-AA finish or gravimetric finish at (i) ALS Laboratories in Val d'Or, Quebec, Vancouver, British Colombia, Lima, Peru or Vientiane, Laos (ii) Bureau Veritas in Timmins, Ontario. The 1-kilogram screen assay method is selected by the geologist when samples contain coarse gold or present a higher percentage of pyrite than surrounding intervals. Selected samples are also analyzed for multi-elements, including silver, using a Four Acid Digestion-ICP-MS method at ALS Laboratories. Drill program design, Quality Assurance/Quality Control ("QA/QC") and interpretation of results is performed by qualified persons employing a QA/QC program consistent with NI 43-101 and industry best practices. Standards and blanks are included with every 20 samples for QA/QC purposes by the Corporation as well as the lab. Approximately 5% of sample pulps are sent to secondary laboratories for check assay.
About the Windfall Gold Deposit
The Windfall gold deposit is located between Val-d'Or and Chibougamau in the Abitibi region of Quebec, Canada. The mineral resource defined by Osisko, as disclosed in the news release dated February 17, 2021 and supported by the technical report entitled "Mineral Resource Estimate Update for the Windfall Project, Eeyou Istchee James Bay, Quebec, Canada" dated March 8, 2021 (with an effective date of November 30, 2020), and assuming a cut-off grade of 3.50 g/t Au, comprises 521,000 tonnes at 11.3 g/t Au (189,000 ounces) in the measured mineral resource category, 5,502,000 tonnes at 9.4 g/t Au (1,668,000 ounces) in the indicated mineral resource category and 16,401,000 tonnes at 8.0 g/t Au (4,244,000 ounces) in the inferred mineral resource category . The key assumptions, parameters and methods used to estimate the mineral resource estimate disclosed in the February 17, 2021 news release are further described in the full technical report prepared by BBA Inc. in accordance with NI 43-101 and is available on SEDAR (www.sedar.com) under the Corporation's issuer profile. The Windfall gold deposit is currently one of the highest-grade resource-stage gold projects in Canada and has world-class scale. Mineralization occurs in three principal zones: Lynx, Main Zone, and Underdog.
Mineralization is generally comprised of sub-vertical zones following intrusive porphyry contacts plunging to the northeast. The r esources are defined from surface to a depth of 1,600 metres as it now includes the Triple 8 (T8) zone. The resources excluding T8 are defined from surface to a depth of 1,200 metres. T he deposit remains open along strike and at depth .
Mineralization has been identified at surface in some areas and as deep as 2,625 metres in others with significant potential to extend mineralization down-plunge and at depth.
