OSISKO MINING RELEASES DISCOVERY 1 PRELIMINARY RESULTS
14.1 g/t Au Over 2.1 Metres Adds 500 Metre Strike Extension to Underdog
9.58 g/t Au Over 7.6 Metres Adds 100 Metre Extension to Triple 8
(Toronto, September 11, 2019) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide an update on the Discovery 1 drill hole. Discovery 1’s principal exploration target is the interpreted outer shell and centre of a possible porphyry intrusion feeding the Windfall-Lynx gold system, at depths of approximately 3,000 metres to 3,500 metres from surface. The drill hole was designed to also target potential depth extensions of two known mineralized zones (the Underdog Zone and Triple 8 Zone). Preliminary results from Discovery 1 include intersections from the targeted Underdog and Triple 8 extensions, noted below. Approximately 2,300 metres down-hole length has been completed, with approximately 1,200 metres left to reach the principal exploration targets.
The initial attempted hole (OSK-W-19-1944) was started on May 10th and was ended at 812 metres length due to excessive deviation. A second attempt (OSK-W-19-1970) was commenced on May 30th, 2019 and has so far completed approximately 2,300 metres of the planned 3,500 metres. Eleven dip corrections have been done at regular spacings up to 2,050 metres using retractable wedges to control deviation.
A new high-grade extension of Underdog Zone was intersected at approximately 1771 metres down-hole depth (14.1 g/t Au over 2.1 metres), 500 metres from the nearest Underdog resource wireframe. This new intercept is a significant new down-plunge extension of the zone, which will be followed up with additional drilling later in the year.
Discovery 1 has also intersected significant new mineralization in the Triple 8 corridor (9.58 g/t Au over 7.6 metres) at 2,191 metres down-hole, adding information and extending the known mineralization in this zone by approximately 100 metres.
Osisko President and Chief Executive Officer John Burzynski commented: “Discovery 1 is already paying dividends with a new 500 metre high-grade extension of the Underdog Zone and a new wide intercept in Triple 8. We are now moving to the really interesting part of this hole and are hoping to get a good look at the potential roots and feeder system of the Windfall deposit as Discovery 1 progresses towards the main deep targets.”

Underdog Extension
The first interval intersected 5.75 g/t Au over 3.2 metres. Mineralization includes local visible gold, 7% pyrite stringers, clusters and locally disseminated hosted in a moderately chloritized, moderately bleached and locally moderately to strongly silicified andesite in contact with felsic porphyritic intrusions with trace large quartz eyes. The second interval returned 62.3 g/t Au over 1.0 metre, with mineralization consisting of centimeter-scale quartz veins in a moderate chlorite and weakly silica and sericite altered andesite. The third interval returned 14.1 g/t Au over 2.1 metres lower down in the Underdog corridor. Mineralization consists of 3% pyrite stringers and 1% disseminated pyrite associated with pervasive silica flooding and a quartz-carbonate vein hosted in a moderately sericitized porphyritic felsic intrusion.
The intervals are located approximately 500 metres down-plunge of the defined Underdog resource and the first two intervals occur in a broader zone of low-grade mineralization and alteration located between 1614.0m – 1686.0m.
Triple 8 Zone
OSK-W-19-1970 intersected 9.58 g/t Au over 7.6 metres in the Triple-8 corridor. Mineralization includes local visible gold in clusters and disseminated associated with patchy silica alteration, up 20% disseminated and clustered pyrite with trace chalcopyrite stringers and up to 1% pyrrhotite hosted in a moderate sericite and silica altered andesite with weak foliation. This intercept is located 100 metres from a prior intersection in OSK-W-18-1783 (16.0 g/t Au over 2.3 metres, see Osisko news release dated February 5, 2019).

OSISKO INTERSECTS BONANZA GRADES AT LYNX EXTENSION AND TRIPLE LYNX
72.3 g/t Au Over 12.7 Metres in Triple Lynx
145 g/t Au Over 3.5 Metres in Lynx Extension
(Toronto, September 9, 2019) 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 infill drilling at the Lynx deposit, exploration and expansion drilling on the main mineralized zones, and deep exploration in the central areas of the mineralized intrusive system. Sixteen drills are active at Lynx and Triple Lynx, with another seven drills conducting infill and exploration drilling on other areas of the deposit.
Osisko President and Chief Executive Officer John Burzynski commented: “The continued flow of strong results from Lynx is making us rethink our approach to the Windfall deposit. We continue to see good continuity of high-grade mineralization at Lynx and now Triple Lynx, and both zones remain open for expansion down-plunge. The Lynx Extension and Triple Lynx are adding important ounces and these two recent discoveries are once again demonstrating the importance of the Lynx corridor in the Windfall mineralized system.”
Significant new analytical results from 14 intercepts in 2 drill holes and 10 wedges from surface focused on Lynx Extension and Triple Lynx drilling are presented below. Maps showing hole locations and full analytical results are available at www.osiskomining.com.

OSISKO INFILL DRILLING INTERSECTS HIGH-GRADE AT LYNX
Multiple High-Grade Intercepts Including 80.7 g/t Au Over 5.8 Metres
(Toronto, September 5, 2019) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new infill drilling results from the ongoing definition and expansion 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 infill drilling within the main Windfall gold deposit and the adjacent Lynx deposit (located immediately NE of Windfall), exploration and expansion drilling on the main mineralized zones, and deep exploration in the central areas of the intrusive system.
Significant new analytical results from 72 intercepts in 38 drill holes and 16 wedges from surface focused on Lynx and Main Zone infill drilling are presented below. Additionally, 66 intercepts in 29 underground drill holes focused on multiple spacing infill drilling, including the pending Lynx bulk sample area, are included in a second table below.
Osisko President and Chief Executive Officer John Burzynski commented: “Infill drilling has been defining good continuity within the known zones and is showing some very strong grades particularly in Lynx. The recently announced addition of 200,000 metres of drilling should also allow us to add significant areas from the two new discoveries (the Lynx Extension and Triple Lynx) to the resource work by the end of the year.”
Highlights from new infill drilling results include: 80.7 g/t Au over 5.8 metres in OSK-W-19-1958-W2; 104 g/t Au over 3.6 metres in OSK-W-19-1539-W1; 151 g/t Au over 2.1 metres in WST-19-0168; 89.2 g/t Au over 2.9 metres in WST-19-167; 114 g/t Au over 2.1 metres in WST-19-0143; 52.3 g/t Au over 4.2 metres in OSK-W-19-2012; 81.0 g/t Au over 2.7 metres in WST-19-0142A; 53.1 g/t Au over 3.3 metres in OSK-W-19-1949-W1; 50.9 g/t Au over 2.5 metres in WST-19-0172; 14.5 g/t Au over 7.3 metres in WST-19-0132 and 50.0 g/t Au over 2.0 metres in OSK-W-19-1412-W3.

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 Lake Gold Deposit
The Windfall Lake gold deposit is located between Val-d’Or and Chibougamau in the Abitibi region of Québec, Canada. The mineral resource defined by Osisko, as disclosed in the Windfall Lake Technical Report (as defined below) and November 27, 2018 Lynx resource update, comprises 2,874,000 tonnes at 8.17 g/t Au (754,000 ounces) in the indicated mineral resource category and 10,352,000 tonnes at 7.11 g/t Au (2,366,000 ounces) in the inferred mineral resource category. For details regarding the key assumptions, parameters and methods used to estimate the mineral resources presented in respect of the Windfall Lake gold project, please see the technical report entitled “Technical Report and Mineral Resource Estimate for the Windfall Lake Project, Windfall Lake and Urban-Barry Properties” and dated June 12, 2018 (effective date of May 14, 2018), which has been prepared by InnovExplo Inc. from Val-d’Or, Québec (the “Windfall Lake Technical Report”) and the press release “Osisko Releases Mineral Resource Update for Lynx” dated November 27, 2018, which has been prepared by Osisko and reviewed and approved by Micon International, Ltd. from Toronto, Ontario. The Windfall Lake Technical Report and press release are available on Osisko’s website at www.osiskomining.com and on SEDAR under Osisko’s issuer profile at www.sedar.com. The Windfall Lake gold deposit is currently one of the highest-grade resource-stage gold projects in Canada. Mineralization occurs in four principal zones: Lynx, Zone 27, Caribou and Underdog. All zones comprise sub-vertical lenses following intrusive porphyry contacts plunging to the northeast. The deposit is well defined from surface to a depth of 900 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.

Qualified Person
The scientific and technical content of this news release has been reviewed, prepared and approved by Mr. Mathieu Savard, P.Geo. (OGQ 510), Vice-President of Exploration, 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 currently unknown but is estimated at 65-80% 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 Columbia. 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. All samples are also analyzed for multi-elements, 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.
About the Osborne-Bell Gold Deposit
The Osborne-Bell gold deposit is located 15 kilometres northwest of the town of Lebel-sur-Quevillon in the Abitibi region of Québec, Canada. The mineral resource defined by Osisko, as disclosed in the Osborne-Bell Technical Report (as defined below), comprises 2,587,000 tonnes at 6.13 g/t Au (510,000 ounces) in the inferred mineral resource.
