OSISKO INFILL DRILLING CONTINUES TO INTERSECT HIGH GRADE
415 g/t Au over 2.0 Metres
149 g/t Au Over 5.6 Metres
(Toronto, March 31, 2020) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new infill drilling results from the definition and expansion drill program at its 100% owned Windfall gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.
The current program is focused on the Lynx deposit, exploration on the main mineralized zones, and deep exploration in the central areas of the mineralized system. Prior to the government mandated temporary shutdown related to the Covid-19 crisis, fifteen surface drills and four underground rigs on the exploration ramp were active at Lynx and Triple Lynx. Significant new analytical results from the infill program are presented below and include from 90 intercepts in 34 drill holes, 12 wedges, and 5 extensions of previous drill holes.
Selected high-grade intercepts from new results include: 149 g/t Au over 5.6 metres in OSK-W-20-2170-W2; 415 g/t Au over 2.0 metres and 85.7 g/t Au over 2.0 metres in OSK-W-20-2100-W7; 337 g/t Au over 2.0 metres and 243 g/t Au over 2.0 metres in WST-20-0295; 21.9 g/t Au over 18.1 metres and 36.9 g/t Au over 9.7 metres in OSK-W-19-1272-W4; 79.1 g/t Au over 2.2 metres and 61.2 g/t Au over 2.3 metres in OSK-W-20-1731-W5; 21.2 g/t Au over 6.0 metres in OSK-W-18-1739.

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 – 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. All NQ core assays reported 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, Québec, Thunder Bay, Ontario, Sudbury, Ontario or Vancouver, British Colombia, or (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 an Aqua Regia-ICP-AES 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 Eeyou Istchee James Bay, Québec, Canada. The mineral resource defined by Osisko, as disclosed in the news release dated February 19, 2020, and assuming a cut-off grade of 3.5 g/t, comprises 4,127,000 tonnes at 9.1 g/t Au (1,206,000 ounces) in the indicated mineral resource category and 14,532,000 tonnes at 8.40 g/t Au (3,938,000 ounces) in the inferred mineral resource category. The key assumptions, parameters and methods used to estimate the mineral resource estimate disclosed in the February 19,2020 news release, certain of which are described in that news release, will be further described in the full technical report being prepared for this updated mineral resource estimate in accordance with NI 43-101, and will be available on SEDAR (www.sedar.com) under the Corporation’s issuer profile within 45 days. 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 deposit is well defined from surface to a depth of 1,200 metres and remains open along strike and at depth. Mineralization has been identified 30 metres from surface in some areas and as deep as 2,000 metres in others, with significant potential to extend mineralization down-plunge and at depth.

OSISKO EXTENTION AND INFILL DRILLING INTERSECTS HIGH GRADE AT LYNX AND TRIPLE LYNX
948 g/t Au Over 2.4 Metres
360 g/t Au over 2.1 Metres
(Toronto, March 9, 2020) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new drilling results from the ongoing definition and expansion drill program at its 100% owned Windfall gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.
The program is currently focused on the Lynx deposit, exploration on the main mineralized zones, and deep exploration in the central areas of the mineralized intrusive system. Nineteen drills are active at Lynx and Triple Lynx.
Osisko President and Chief Executive Officer John Burzynski commented: “This first major set of new drill results following, and not included in, last month’s mineral resource estimate update continues to show high-grade results from Lynx in both infill and expansion holes. The drilling demonstrates very good potential for further growth of scale and grade at Lynx. While the focus of the drill program is on resource definition, the exploration team is excited about targeting several key areas of the Lynx deposit for growth potential, in particular a down-plunge projection where we believe Lynx Extension and Triple Lynx zones may intersect.”
The first results table below lists expansion intercepts located outside the February 2020 mineral resource estimate wireframes (see Osisko news release dated February 19, 2020). The second table shows infill intercepts designed for resource definition. Significant new analytical results from 173 intercepts in 57 drill holes, 31 wedges, and 3 extensions of previously completed holes are presented below.
Selected high-grade intercepts from new results include: 948 g/t Au over 2.4 metres in OSK-19-2226; 360 g/t Au over 2.1 metres in OSK-W-19-2164; 72.0 g/t Au over 5.1 metres in OSK-W-19-2197-W1; 139 g/t Au over 2.0 metres in OSK-W-20-1104-W7; 71.2 g/t Au over 3.4 metres in OSK-W-19-1731-W4; 113 g/t Au over 2.0 metres in WST-19-0266; 19.0 g/t Au over 11.2 metres in OSK-W-19-2100-W5; 58.4 g/t Au over 3.2 metres in OSK-W-19-2123-W3; 92.6 g/t Au over 2.0 metres in OSK-W-19-991-W9; 51.0 g/t Au over 3.2 metres in WST-19-0198 and 41.1 g/t Au over 3.5 metres in OSK-W-19-991-W10.

Lynx Zone
Mineralization in the Lynx zone is typically characterized by trace to 15% disseminated, clustered or stringer pyrite (locally up to 70%), local visible gold, trace to 3% sphalerite, chalcopyrite, and galena, local ptygmatic pyrite-tourmaline or tourmaline veinlets, quartz-carbonate veins (locally crustiform), smoky quartz veins and veinlets, and local chlorite-calcite or quartz-carbonate chlorite fracture filling. Alteration consists of weak to strong sericite, weak to strong silica with areas of local pervasive silica flooding, weak to moderate chlorite and carbonate, and locally weak to strong fuchsite. Mineralization is hosted in or at the contacts of felsic porphyritic or fragmental intrusions with rhyolites, andesites (locally bleached), or gabbros.
Triple Lynx Zone
Mineralization in the Triple Lynx zone is typically characterized by trace to 30% disseminated, clustered or stringer pyrite, local visible gold, trace sphalerite, chalcopyrite, and galena, local quartz-tourmaline veins (up to 20%), local ptygmatic tourmaline veins, and local smoky quartz and quartz-carbonate veins. Alteration consists of weak to strong sericite, weak to strong silica with areas of local pervasive silica flooding, weak to moderate chlorite and carbonate, and locally weak to strong fuchsite. Mineralization is hosted in or at the contacts of felsic porphyritic dikes with rhyolites (locally bleached) or gabbros.

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. All NQ core assays reported 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, Québec, Thunder Bay, Ontario, Sudbury, Ontario or Vancouver, British Colombia, or (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 an Aqua Regia-ICP-AES 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 Eeyou Istchee James Bay, Québec, Canada. The mineral resource defined by Osisko, as disclosed in this news release and assuming a cut-off grade of 3.5 g/t, comprises 4,127,000 tonnes at 9.1 g/t Au (1,206,000 ounces) in the indicated mineral resource category and 14,532,000 tonnes at 8.40 g/t Au (3,938,000 ounces) in the inferred mineral resource category. The key assumptions, parameters and methods used to estimate the mineral resource estimate disclosed in this news release, certain of which are described in this news release, will be further described in the full technical report being prepared for this updated mineral resource estimate in accordance with NI 43-101, and will be available on SEDAR (www.sedar.com) under the Corporation’s issuer profile within 45 days. 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 deposit is well defined from surface to a depth of 1,200 metres and remains open along strike and at depth. Mineralization has been identified 30 metres from surface in some areas and as deep as 2,000 metres in others, with significant potential to extend mineralization down-plunge and at depth.
