742 g/t Au Over 2.2 Metres in Zone 27

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

(Toronto, August 22, 2018)  Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new infill drilling results from the ongoing drill definition and expansion 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 commenced in late 2015. The program is now focussed on infill drilling within the main Windfall gold deposit and the adjacent Lynx deposit (located immediately NE of Windfall), and exploration and expansion drilling on main mineralized zones with several deep holes in progress to investigate the down-plunge areas in and around the Underdog and Lynx zones.

 

Significant new analytical results from 80 intercepts in 53 drill holes and one wedge focused on infill of the Main Windfall Lake and Lynx deposits and on deep-exploration targets are presented below.

Highlights from the new results include: 510 g/t Au over 5.2 metres in OSK-W-18-1639; 742 g/t Au over 2.2 metres in OSK-W-18-1589; 21.6 g/t Au over 19.4 metres in OSK-W-18-1655; 198 g/t Au over 2.0 metres in OSK-W-18-1638; 25.7 g/t Au over 8.9 metres in OSK-W-17-1313.

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 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 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), 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. 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”). The Windfall Lake Technical Report 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.

OSISKO MINING TO ACQUIRE BEAUFIELD RESOURCES

Beaufield

NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES

Toronto, Ontario (August 14, 2018) – Osisko Mining Inc. (TSX: OSK) (“Osisko”) and Beaufield Resources Inc. (TSX-V: BFD) (“Beaufield”) are pleased to announce that they have entered into a definitive arrangement agreement dated August 14, 2018 (the “Arrangement Agreement”) pursuant to which Osisko has agreed to acquire all of the issued and outstanding common shares of Beaufield (collectively, the “Beaufield Shares” and each whole share, a “Beaufield Share”) which it does not already own (the “Acquisition”). The Acquisition is expected to be completed by way of a statutory plan of arrangement under the Canada Business Corporations Act (the “Arrangement”).

John Burzynski, President and Chief Executive Officer of Osisko, stated: “We are very pleased to announce today’s proposed transaction with Beaufield. By joining Osisko in our large scale exploration and development program at Windfall, Beaufield Shareholders have the opportunity to capitalize on the strong premium offered today and to benefit from the future growth of our project.”

Ron Stewart, President and Chief Executive Officer of Beaufield, stated: “We are very pleased to be joining forces with Osisko, which continues to demonstrate its leadership and strength in advancing its portfolio of resource projects including the flagship Windfall district. We believe the combination of our projects will provide benefit to the shareholders of both companies and look forward to participating in the future success of Osisko.”

Particulars of the Transaction

Under the terms of the Arrangement Agreement, holders of Beaufield Shares (“Beaufield Shareholders”) will be entitled to receive 0.0482 of a common share of Osisko (each whole share, an “Osisko Share”) in exchange for each Beaufield Share held immediately prior to the effective time of the Arrangement, representing an implied offer price of $0.082 per Beaufield Share based on Osisko’s closing price as of August 14, 2018 and a premium of approximately 54% based on the 20-day volume weighted average price of both companies’ common shares on the Toronto Stock Exchange and TSX Venture Exchange, as the case may be, on August 14, 2018 (being the last trading day prior to the announcement of the Arrangement).

The Arrangement will require the approval of Beaufield Shareholders at a special meeting expected to take place in October 2018 (the “Beaufield Meeting”).

Directors and officers of Beaufield and certain Beaufield Shareholders holding approximately 7.5% of the issued and outstanding Beaufield Shares have entered into voting and support agreements with Osisko in support of the Arrangement. The board of directors of Beaufield, on the recommendation of its independent special committee, has unanimously approved the Arrangement and will recommend that Beaufield Shareholders vote FOR the Arrangement.

The Arrangement Agreement includes representations, warranties and covenants typical of a transaction of this nature, including with respect to non-solicitation, a right to match, and a fiduciary-out. In addition, Beaufield has agreed to pay a termination fee to Osisko upon the occurrence of certain events. The Arrangement Agreement, which describes the full particulars of the Arrangement, will be made available on SEDAR under the issuer profile of Beaufield at www.sedar.com.

OSISKO DEEP DRILLING GOLD DISCOVERY AT WINDFALL

650 Metres Down Plunge From Triple 8 Discovery Hole
22.4 g/t Au Over 3.4 Metres

(Toronto, August 7, 2018)  Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide new results from the ongoing deep-hole exploration program at its 100% owned Windfall Lake gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.

 

In May 2018 Osisko commenced two deep exploration drill holes (“Deep Underdog” and “Deep Lynx”) to investigate the potential for depth extensions of the Lynx and Underdog mineralized zones, as well as to further test the intrusion-related geological model for the Windfall deposit at depths of approximately 2500 metres from surface.  Drilling on the Deep Lynx hole is still in progress, and wedge holes for both Deep Lynx and Deep Underdog are planned.

 

Following the discovery of Triple 8 Zone in the “Deep Underdog” hole (as disclosed in Osisko’s news release dated July 11, 2018), the down-plunge projection of the gold mineralized structure was interpreted to lie in the path of the “Deep Lynx” hole, OSK-W-18-1616-W1, at target depth of approximately 1950 meters downhole. Alteration and mineralization related to the new intersection occurs in the Deep Lynx hole between 1985.1 metres and 1991.5 metres downhole (approximately 1900 metres vertical depth from surface), including two intervals containing visible gold.  Maps and sections showing the location of the Deep Lynx drill hole and the new mineralized zone are provided on the Corporation’s website.

 

The new gold bearing zone appears to be sub-vertical and has an estimated true thickness of 2.5 metres. Mineralization occurs as up to 12% pyrite stringers, pyrrhotite, chalcopyrite and local visible gold associated with minor quartz-carbonate veins. The hosting andesite is bleached, with sericite alteration and is crosscut by metre scale felsic porphyritic dike. Exact geometries and relationship to the Triple 8 discovery is currently unknown.  Drilling in the Deep Lynx hole is still in progress.  Wedge holes are being planned to further investigate the new mineralized zone.

 

Osisko President and CEO John Burzynski commented: “We are very pleased with the continuing success of our deep hole exploration program at Windfall.  Our geological model is predicting where to find new extensions of our deposit, and our extensive drill program is key in defining what we believe is a World Class gold system.  We are currently planning wedge holes for the Triple 8 discovery area and this new potential extension to better understand the geometry of the gold mineralization in this exciting discovery.”

 

Today’s results include only partial significant analytical results from hole OSK-W-18-1616-W1. Maps showing hole locations and full analytical results are available at www.osiskomining.com.

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), 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. 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”). The Windfall Lake Technical Report 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.

Cautionary Statement Regarding Technical information

Readers are cautioned that the Windfall PEA is preliminary in nature and includes inferred mineral resources that are too speculative geologically to have economic considerations applied to them that would enable them to be categorize as mineral reserves. There is no certainty that the results, assumptions or estimates in the Windfall PEA will be realized. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
