Osisko Intersects 56.1 g/t Au Over 8.9 Metres at Windfall

TORONTO, ONTARIO--(Marketwired - Jan 25, 2018) - Osisko Mining Inc. (TSX:OSK)("Osisko" or the "Corporation") is pleased to provide new results from the ongoing drill program at its 100% owned Windfall Lake gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec. The 800,000 metre drill program combines definition, expansion and exploration drilling in and around the main Windfall gold deposit and the adjacent Lynx deposit (located immediately NE of Windfall).

Significant new analytical results from 72 intercepts in 39 drill holes and 6 wedges focused on infill and expansion drilling in the Main Windfall lake deposit are presented below.

• New "Bobcat Zone" with high-grades discovered near surface and at shallow depths
• Continued high-grade infill and expansion from Underdog
• New hit from Drake

Highlights from the new results include: 56.1 g/t Au over 8.9 metres in OSK-W-17-1336-W1; 218 g/t Au over 2.1 metres in OSK-W-17-1191; 160 g/t over 2.0 metres in OSK-W-17-1142-W1; 106 g/t Au over 3.0 metres in OSK-W-17-1305; 30.8 g/t over 9.9 metres in OSK-OBM-16-693; 83.5 g/t Au over 3.4 metres in OSK-W-17-780-W1; 128 g/t Au over 2.1 metres in OSK-W-17-1203; 58.8 g/t Au over 2.5 metres in OSK-W-17-1095; 72.8 g/t Au over 2.0 metres in OSK-W-17-1020; 42.4 g/t Au over 3.3 metres in OSK-W-17-1138; 52.8 g/t Au over 2.3 metres in OSK-W-17-1381; 26.2 g/t Au over 3.8 metres in OSK-W-17-1374; 41.9 g/t Au over 2.0 metres in OSK-W-17-1289; 14.1 g/t Au over 5.6 metres in OSK-W-17-1255; and 26.5 g/t Au over 2.1 metres in OSK-W-17-1142.

The first interval is in a porphyritic felsic dike and the three others are in crustiform veins within a silicified rhyolite.

Zone 27 results also include 12 intercepts from 7 drill holes and one wedge. Mineralization is composed of up to 15% pyrite, disseminated or in stringers associated with quartz-tourmaline veins. Host rocks are rhyolites, andesites and felsic dikes.

Caribou results also include 18 intercepts from 12 drill holes. Mineralization is composed of up to 20% pyrite, usually in stringers, locally semi-massive, and quartz-tourmaline veins hosted in altered porphyritic felsic dikes, andesites and rhyolites.

Wolf results include 4 intercepts from 2 drill holes and 2 wedges. Mineralization is composed of up to 70% pyrite-silica flooding, up to 20% pyrite stringers, and ptygmatic tourmaline veins hosted in silicified, sericitized and fuchsitized andesite.

Underdog results also include 4 intercepts from 4 drill holes. Mineralization is composed of up to 20% pyrite, usually in stringers associated with trace quartz-tourmaline veins and hosted in porphyritic felsic dikes. Host dikes are strongly silica altered.

Bobcat results also include 11 intercepts from 7 drill holes. Mineralization is composed of up to 10% pyrite-silica flooding, up to 5% disseminated pyrite and crustiform quartz veins within chloritized, sericitized andesites, rhyolites and felsic dikes.

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 the 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 widths determinations are estimated at 65-80% of the reported core length intervals for most of the zones. 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 ALS Laboratories in Val d'Or, Québec, Thunder Bay and Sudbury, Ontario or Vancouver, British Colombia or 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 the previous operator comprises 2,762,000 tonnes at 8.42 g/t Au (748.000 ounces) in the indicated category and 3,512,000 tonnes at 7.62 g/t Au (860,000 ounces) in the inferred category (sourced from a technical report dated June 10, 2015 entitled "Preliminary Economic Assessment of the Windfall Lake Gold Property, Québec, Canada" with an effective date of April 28, 2015, prepared in accordance with NI 43-101). The Windfall Lake gold deposit is currently one of the highest grade resource-stage gold projects in Canada. The bulk of the mineralization occurs in the Main Zone, a southwest/northeast trending zone of stacked mineralized lenses, measuring approximately 600 metres wide and at least 1.400 metres long. The deposit is well defined from surface to a depth of 500 metres, and remains open along strike and at depth. Mineralization has been identified only 30 metres from surface in some areas and as deep as 870 metres in others, with significant potential to extend mineralization up and down-plunge and at depth.
