Osisko Intersects 97.6 g/t Au Over 3.3 Metres at Lynx TORONTO, June 07, 2018 (GLOBE NEWSWIRE) -- Osisko Mining Inc. (OSK:TSX) ("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, Qubec. The 800,000 metre drill program commenced in late 2015 is now focussed on infill drilling within the main Windfall gold deposit and the adjacent Lynx deposit (located immediately NE of Windfall). Exploration and expansion drilling is also continuing at Windfall with several deep holes in progress to investigate the down-plunge areas in and around the Underdog and Lynx zones.
Today's results include significant new analytical results from 49 intercepts in 28 drill holes and 2 wedges focused on infill drilling in the Lynx deposit.
Highlights from the new results include: 97.6 g/t Au over 3.3 metresin OSK-W-18-1511; 79.1 g/t Au over 2.7 metres in OSK-W-18-909-W5; 74.3g/t Au over 2.6 metres in OSK-W-18-1536; 64.2 g/t Au over 3.0 metres in OSK-W-18-1470; 42.8 g/t Au over 2.3 metres in OSK-W-17-1098; 20.1 g/t Au over 3.7 metres in OSK-W-18-1477; and 14.5 g/t Au over 4.7 metres in OSK-W-18-1496.

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 (i) ALS Laboratories in Val d'Or, Qubec, 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 Qubec, Canada. The mineral resource defined by Osisko, as disclosed in a press release disseminated by the Corporation on May 14, 2018, comprises 2,382,000 tonnes at 7.85 g/t Au (601,000 ounces) in the indicated mineral resource category and 10,605,000 tonnes at 6.70 g/t Au (2,284,000 ounces) in the inferred mineral resource category (see press release entitled "Osisko Releases Its First Mineral Resource Estimate for Windfall Gold Deposit" dated May 14, 2018, which is 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 only 30 metres from surface in some areas and as deep as 1,200 metres in others, with significant potential to extend mineralization down-plunge and at depth.
