(Toronto, September 16, 2020) Osisko Mining Inc. (OSK:TSX) (“Osisko” or the “Corporation”) is pleased to provide the following corporate update.
Mr. John Burzynski has been appointed as Chairman of the board of directors and remains in his role as Chief Executive Officer and as a director; Mr. Sean Roosen has stepped down from his role as non-executive Chairman of the board and remains in his role as a director; and Mr. Mathieu Savard has been promoted to President.
A graduate of the Université du Québec à Montréal with a bachelor’s degree in earth sciences with over 20 years’ experience in the mining industry, Mr. Savard served previously as Osisko’s Senior Vice-President Exploration. Prior to joining Osisko Mining in 2016, Mathieu was a senior member of the Osisko Exploration James Bay, Virginia Gold and Virginia Gold Mines teams. Mathieu was a key member of the Virginia team which received the Association de l’Exploration Minière du Quebec (“AEMQ”) Prospector of the Year Award in 2004 and the PDAC’s prestigious Bill Dennis Award in 2006 for the discovery of the Eleonore gold deposit, and along with the Osisko Mining management and exploration team received the AEMQ 2017 Discovery of the Year Award, for the discovery of the Lynx deposit at Windfall. Mathieu is a registered P.Geo. as a member of the Ordre des Géologues du Québec and is Chairman of the board and a director of the AEMQ.
Chief Executive Officer and Chairman of the Corporation John Burzynski commented: “I would like to thank Sean Roosen very much for his past tenure as Chairman, and for continuing in his role as a director. I am very pleased to welcome Mathieu as the incoming President of Osisko Mining, and I look forward to him leading our team in the next stages of the work at Windfall, and to making additional discoveries in the coming years. Our goal on the re-creation of Osisko Mining in 2015 was to discover and develop another world class gold mine in Québec. We acquired a promising deposit, a district-scale land package, assembled one of the best exploration teams in the business, and commenced one of the world’s largest drill programs at Windfall. Five years of persistence and hard work have paid off with the discovery of Lynx and the delineation of a world class deposit.
Osisko’s management and Board has had an unusual level of success in the Canadian mining business, leading to the last three world class gold discoveries in Québec (Windfall, Canadian Malartic, and Eleonore). Our independent Lead Director was additionally responsible for leading the team that discovered the world class Fruta del Norte deposit in Ecuador. All this to say that at Osisko we have a strong and highly experienced Board and management team, one of the finest and most capable technical teams in the business, and one of the most proven track records of gold discovery and value creation for shareholders amongst any of our peers. I have every confidence that Mathieu’s strong leadership skills will continue to take us to new heights.”

Drill hole location
|Hole Number||Azimuth (°)||Dip (°)||Length (m)||UTM E||UTM N||Elevation||Section|
Mineralization occurs as grey to translucent quartz-carbonate-pyrite-tourmaline veins and pyrite replacement zones and stockworks. The vein-type is associated with haloes of pervasive sericite-pyrite ± 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 ± 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.
Mineralization most commonly occurs in gold-bearing pyrite stockworks as well as semi-massive pyrite replacement zones associated with phyllic alteration (sericite-pyrite ± silica) with sulphides, pyrite dominated with minor chalcopyrite and sphalerite ranging from trace to up to 20%, and local visible gold. Mineralization is hosted in rhyolites or mafic-intermediate volcanics frequently at or near faults or the contact with felsic porphyritic intrusions.
Mineralization is hosted in sheared andesites with carbonate replacement or quartz veining and occurs as quartz ± ankerite veinlets or in shear zones as replacement, characterised by trace to 10% pyrite with local visible gold. Alteration is dominated by sericite-fuchsite-tourmaline-pyrite.
Mineralization is hosted in sheared mafic volcanics with felsic porphyritic intrusions and occurs as veins associated with sericite-pyrite ± silica ± chlorite alteration and contains pyrite ranging from trace to 30% and local visible gold.
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, QualityAssurance/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 supported by the technical report entitled “An updated mineral resource estimate for the Windfall Lake Project, Located in the Abitibi Greenstone Belt, Urban Township, Eeyou Istchee James Bay, Québec, Canada” and dated April 3, 2020 (with an effective date of January 3, 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 are further described in the full technical report prepared by Micon International Limited (“Micon”) and BBA Inc (“BBA”), in accordance with NI 43-101 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 deformed sub-vertical zones plunging to the northeast. Vein-type or pyrite replacement-type styles of mineralization crosscut syn-volcanic host rocks and syn-deformation felsic porphyry intrusions and are spatially associated with the contacts of the intrusions. 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.
