OSISKO WINDFALL 2023 DRILLING UPDATE REGIONAL EXPLORATION TO RESUME

New Results Include 413 g/t Au Over 8.0 Metres

and 623 g/t Au Over 3.0 Metres

(Toronto, October 26, 2023) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to provide an update from the ongoing drill program at its 50% owned Windfall gold project located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec.

The 2023 drilling campaign primarily targeted infill areas. Since the start of the year, over 95,000 metres have been drilled by 8 underground rigs focused on the Lynx segment of the deposit.

Highlights from the 2023 drill program are presented below and include 320 intercepts from 248 drill holes and 1 wedge. These highlights are intercepts with a metal factor (grams*meters) greater than 20. The intercepts are all located within the defined mineral resource estimate (“MRE”) blocks as described in Osisko’s feasibility study on Windfall (see FS Technical Report (as defined herein), a copy of which is available on SEDAR+ under Osisko’s issuer profile), and have targeted upgrading inferred mineral resources to measured or indicated mineral resources or indicated minerals resources to measured mineral resources as applicable.

Osisko Chief Executive Officer John Burzynski commented: “Infill drilling at the Windfall deposit is progressing well and confirming our models. High-grade gold continues to be intercepted in the Lynx areas including Triple Lynx, once again highlighting the world-class nature of the deposit. Of note, we have more than ten intervals in this set of numbers that returned values over one kilogram per tonne of gold. Infill drilling will continue into next year. We and our joint venture partner are very much looking forward to resuming exploration on our greater than 2,300 square kilometer land package around Windfall in the coming months”.

Regional exploration in the Urban Barry area will recommence on near-deposit and regional grassroots targets. Exploration will include ground geophysics and diamond drilling of various targets.

Lynx Zone

Mineralization occurs as grey to translucent quartz-carbonate-pyrite-tourmaline veins and pyrite replacement zones and stockworks. Vein-type mineralization 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.

 

Qualified Person

The scientific and technical content of this news release has been reviewed, prepared, and approved by Ms. Isabelle Roy, P.Geo. (OGQ 535), Director of Technical Services for Osisko’s Windfall 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 3.5 g/t Au diluted over core lengths of at least 2.0 metres. NQ core assays 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, Vancouver, British Colombia, Lima, Peru or Vientiane, Laos (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 a Four Acid Digestion-ICP-MS 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.

OSISKO MINING AND GOLD FIELDS ANNOUNCE 50/50 JOINT VENTURE ON WINDFALL GOLD PROJECT

Osisko Fully-Funded to Mine Production
Project to Benefit From Mine Building and Operating Experience of a Senior Gold Producer
Significant Investment by Gold Fields Validates Quality and Robustness of Windfall

 

(Toronto, May 2, 2023) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation“) is pleased to announce it has concluded a 50/50 joint venture agreement with a subsidiary of Gold Fields Limited (“Gold Fields“) for the joint ownership and development of Osisko’s Windfall gold project, located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec (the “Transaction“).

Transaction Highlights

  • Gold Fields initial cash payment to Osisko of C$300 million on signing.
  • Gold Fields additional (“Deferred”) cash payment to Osisko of C$300 million on issuance of the applicable permits authorizing the construction, operation and mining of the Windfall Project.
  • Gold Fields to sole fund expenditures for regional exploration up to a maximum of C$75 million, after which regional exploration programs would be proportionately funded by each of Osisko and Gold Fields.
  • In addition to the initial cash payment and the Deferred cash payment, Gold Fields to make two additional separate C$17 million cash payments to Osisko (C$34 million in total, the first on July 31, 2023 and the second on December 31, 2023). These represent reimbursement of items already incurred by Osisko as part of pre-construction spend.
  • Gold Fields and Osisko share all pre-construction costs (provisional budget estimated at C$250 million) and construction costs (feasibility capital expenditure estimated at C$789 million) on a 50/50 basis going forward.
  • Governance arrangements with equal representation in the Partnership from Osisko and Gold Fields, to leverage each party’s skillsets.

Osisko’s Chairman and Chief Executive Officer, John Burzynski, stated: “We are very pleased to partner with Gold Fields on the Windfall project and our exploration property portfolio. Today is the start of what we believe will prove to be a long and fruitful partnership with Gold Fields at Windfall, and in what we both believe is a significant emerging gold district in Québec. This partnership further strengthens our strong balance sheet, allows us to significantly de-risk Windfall and brings us a very important step closer to realizing our objective of becoming a leading Canadian gold producer. With the proceeds from this Transaction, Osisko is fully-funded for our share of development capital to bring Windfall into production. Osisko shareholders retain considerable upside in the project while also benefiting from the mine building, operating and technical expertise of Gold Fields. Assuming the project is ultimately permitted and approved by the partners consistent with the Windfall Feasibility Study, Gold Fields’ acquisition cost, exploration commitment, and contribution to pre-construction and project capital would ultimately represent an investment of C$1.2 billion to acquire its interest, bring Windfall into production and further unlock the regional exploration upside.  This Transaction is highly compelling on many fronts and represents the best path forward to maximize value for all stakeholders.”

 Mr. Burzynski continued: “Osisko Mining would like to acknowledge and thank Sean Roosen in particular and the directors of Osisko Gold Royalties Ltd. (“OGR”) for their forward-looking vision in supporting the 2015 re-creation of Osisko Mining – one of the key first investment decisions in OGR’s very innovative and successful “accelerator model” concept to create new high-value negative-cost royalties tied to equity investment in new exploration companies.   OGR holds a 2% – 3% NSR royalty on the Windfall area claims and 13% of the undiluted equity in the Corporation.”

 

Transaction Details

The Transaction closed on May 2, 2023, with Gold Fields acquiring a 50% partnership interest in the “Windfall Mining Group”, a partnership formed under the laws of the Province of Ontario (the “Partnership“), which will develop the Windfall project and the surrounding Urban Barry and Quévillon exploration properties (collectively, the “Property“). The Transaction was implemented in accordance with, among other things, a framework agreement dated May 2, 2023 (the “Framework Agreement“) among Osisko, Gold Fields, Gold Fields Holdings Company Limited, Windfall Mining Group and 1000516419 Ontario Inc., the manager of the Partnership (the “Manager“). Pursuant to the terms of the Framework Agreement, Gold Fields acquired 50% interest in the Partnership for an aggregate consideration of C$600 million in cash to Osisko. The Partnership Agreement also requires Gold Fields to sole fund up to C$75 million in contributions to the Partnership for regional exploration. Prior to the acquisition of the 50% Partnership interest by Gold Fields, Osisko had contributed to the Partnership the Property together with any claims, permits, leases, all other real property, personal property, contractual rights and other assets currently held or acquired for the benefit of the Property.

The Framework Agreement contains customary representations and warranties, covenants and indemnification provisions for a transaction of this nature. The obligations of Gold Fields are guaranteed by Gold Fields Holdings Company Ltd, a significant intermediate holding company with material indirect interests in a number of Gold Fields operations.

OSISKO SUBMITS WINDFALL ENVIRONMENTAL IMPACT ASSESMENT

(Toronto, March 29, 2023) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to announce that it has submitted the Environmental Impact Assessment Report for its Windfall project (“Windfall EIA”) to the Environmental and Social Impact Review Committee (“COMEX”). The Windfall project is located in the Abitibi greenstone belt, Urban Township, Eeyou Istchee James Bay, Québec entirely on the traditional land of the Cree First Nation of Waswanipi.

The Windfall EIA was prepared by WSP Canada Inc. with contributions from Arkéos Inc., GCM Consultants, BBA Inc., Entech and Aviseo, each of which is an independent firm and realized in accordance with the Directive issued by the Ministère de l’Environnement, de la Lutte contre les changements climatiques, de la Faune et des Parcs (“MELCCFP”). These contributors provided technical inputs for the study, collected survey data and compilations in all fields required to evaluate the project impacts. Windfall EIA and all supporting documents are available on the Corporation’s website at www.osiskomining.com. The Windfall EIA was coordinated by Vanessa Milette, Osisko’s Director of Environment, under the supervision of Andréanne Boisvert, Osisko’s Vice-President of Environment and Community Relations.

The Windfall project is located south of the 55th parallel in the territory governed by the James Bay and Northern Québec Agreement (JBNQA), which is subject to the COMEX. The COMEX is an independent body composed of members appointed by the governments of Québec and the Cree Nation, which is responsible for the assessment and review of the social and environmental impacts of the Windfall project. Upon completion of the project review, the COMEX will issue a recommendation to the Deputy Minister of Québec’s MELCCFP. Should a positive recommendation be granted by the COMEX, the Deputy Minister would then issue a Certificate of Authorization pursuant to section 164 of Québec’s Environment Quality Act for the Windfall project. The issuance of such Certificate of Authorization is a pre-condition to Osisko applying for the other authorizations required to begin the construction of, and operations at, the Windfall site.

The Windfall EIA covers 18 fields of study from impacts on water, air and vegetation to impacts on regional and provincial economies. The following represents some of the highlights1 of the study as related to benefits to local communities and governments:

 

  • The creation of 17,120 full-time equivalent jobs in Québec by 2035 (direct and indirect jobs), of which 10,256 would be directly in Abitibi-Temiscamingue and Nord-du-Québec regions.
  • Robust water management planning using a state-of-the-art water treatment plant integrated into the proposed future development plan
  • A tailings management facility designed to the highest modern industry standards
  • $3.5 billion of investment2 for construction, sustaining costs and operations by 2035, with an additional $83 million reserved for future closure costs
  • $2.3 billion of contribution to Québec’s GDP by 2035
  • Gross provincial tax revenues for Québec estimated at $712 million (including mining duties), and $333 million gross federal tax revenues by 20353
  • An estimated $68 million in local property taxes and school tax revenues by 2035

 

Notes on the Windfall EIA highlights

1)-Economic and fiscal impacts including contribution to Québec’s GDP were determined by Aviseo Conseil by applying EcoTec’s cross-sector (input-output) model. Estimation of corporate income tax, mining duties, local property and school tax were estimated based on the FS Technical Report (as defined herein), a copy of which is available on SEDAR (www.sedar.com) under Osisko’s issuer profile. All monetary amounts are reported in Canadian dollars. Details about methodology or main hypothesis are described in Windfall EIA and are based on FS Technical Report.  2)-The cumulative $3.5 billion of investments includes Initial Capex of $788 million, Sustaining Capex of $588 million and cumulative operation costs over LOM of $2,134 million based on FS Technical Report.3) -Gross provincial tax estimated contributions includes workers personal income taxes, health services funds and sales taxes while gross federal  tax contributions includes workers personal income taxes.

Osisko’s Chairman and Chief Executive Officer, John Burzynski, stated: “Today’s Windfall Project EIA submission constitutes a significant milestone in realizing our goal of creating a new producing gold mine in Eeyou Istchee James Bay. This submission begins the permitting and authorization process for the Windfall gold project. Osisko enters this process fully aware of the importance of the promoter’s role and responsibilities during the COMEX review process.  The Corporation is committed to transparently delivering an environmentally sound, robust project for all stakeholders, and to provide all project information requested in a timely matter. We would like to thank our host communities the Cree First Nation of Waswanipi and Lebel-sur-Quévillon for their continuous support, and we thank our employees and consultants for their diligent work in delivering this extensive Windfall EIA.”

OSISKO ANNOUNCES DEFINITIVE AGREEMENT WITH MIYUUKAA TO TRANSPORT HYDROELECTRIC POWER TO WINDFALL PROJECT

Hook-up expected Q1-2024

(Toronto, March 16, 2023) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) is pleased to announce that it has concluded the previously announced binding term sheet agreement and signed a definitive agreement with Miyuukaa Corp. (“Miyuukaa”), a wholly-owned corporation of the Cree First Nation of Waswanipi (“CFNW”), with respect to the construction of proposed transmission facilities and the transport of hydroelectric power to the Windfall Project, located in the Abitibi greenstone belt, Eeyou Istchee James Bay, Québec. The power line from the Waswanipi substation to Windfall is located 100% on CFNW traditional lands covered by the James Bay Northern Québec Agreement.

Miyuukaa will finance, build, own and operate a 69 kV dedicated transmission line that will transport hydroelectricity to the Windfall project. As an end user, Osisko will pay service fees to Miyuukaa. The agreement outlines the general and financial terms of the agreement between Osisko and Miyuukaa, which is for the purpose of ensuring delivery of hydroelectricity over the life of the planned Windfall mill as required.
Construction work commenced during the first quarter of 2023 and is projected to take 12 months to complete, with the hook-up date anticipated in Q1 2024.

This agreement solidifies the collaborative approach between Osisko and the CFNW to sustainably develop energy infrastructure, which will create robust employment opportunities for members of the CFNW. Using hydroelectric power through the final stages of exploration and throughout the planned construction and operations phases will reduce greenhouse gas emissions and the Windfall Project’s dependency on fossil fuels.

The Windfall Resource Estimate, assuming a cut-off grade of 3.50 g/t Au, comprises 811,000 tonnes at 11.4 g/t Au (297,000 ounces) in the measured mineral resource category, 10,250,000 tonnes at 11.4 g/t Au (3,754,000 ounces) in the indicated mineral resource category and 12,287,000 tonnes at 8.4 g/t Au (3,337,000 ounces) in the inferred mineral resource category. The Windfall Reserve Estimate, assuming 3.5 g/t operating, 2.5 g/t incremental, and 1.7 g/t development cut-off grade, comprises 12,183,000 tonnes at 8.06 g/t Au (3,159,000 ounces) in the probable mineral reserves category. The key assumptions, parameters, limitations and methods used in the Feasibility Study for Windfall, including the related Windfall Resource Estimate and Windfall Reserve Estimate, are described in a technical report (the “FS Technical Report”), which was prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). The FS Technical Report is available on SEDAR (www.sedar.com) under Osisko’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 areas: Lynx, Main, and Underdog. Mineralization is generally comprised of sub-vertical lenses following intrusive porphyry contacts plunging to the northeast. The resources are defined from surface to a depth of 1,600 metres, including the Triple 8 (TP8) zone. The reserves are defined from surface to a depth of 1,100 metres. The deposit remains open along strike and at depth. Mineralization has been identified at surface in some areas and as deep as 2,625 metres in others with significant potential to extend mineralization down-plunge and at depth.

OSISKO MINING CORPORATE UPDATE

 

 

(Toronto, February 22, 2023) Osisko Mining Inc. (OSK:TSX. “Osisko” or the “Corporation”) provides the following corporate update.

The Corporation continues to advance work on the Windfall project and surrounding properties, with 15 rigs in total active underground and at surface, performing a combination of infill and exploratory drilling.  Detailed engineering has commenced for the planned Windfall operations with the objective of optimizing design and capital expenditures.

The exploration ramp is currently at 640 metres vertical depth, and over 13 kilometres length underground.  Nine drills are active on the exploration ramp, and the advance towards the fourth bulk sample (the 800 metre level Lynx 4 sample) is planned to resume in H2 2023.

Osisko is also working towards the conclusion of the definitive agreement with Miyuukaa Corp. (“Miyuukaa”), a wholly-owned corporation of the Cree First Nation of Waswanipi (“CFNW”), with respect to the construction of proposed transmission facilities and the transport of hydroelectric power to the Windfall project.  The Kuikuhaacheu transmission line from the Waswanipi substation to Windfall is located 100% on CFNW traditional lands covered by the James Bay Northern Québec Agreement. Finalization of the definitive agreement is expected before the end of this month.

The Corporation remains on schedule to submit its Environmental Impact Assessment report for Windfall (“EIA”) to the Environmental and Social Impact Review Committee (“COMEX”) in Q1 2023.  The Corporation also anticipates finalizing the Impact and Benefit Agreement with the Cree First Nation of Waswanipi and the Cree Nation Government before year end 2023.

The Corporation has also begun to receive pre-ordered mill components at the port of Bécancour, Québec.  Equipment is being kept in a dry and heated storage facility until required at the Windfall site.

Having completed its Feasibility Study, Osisko has begun the process of reviewing its financing options for the Windfall mine, including ongoing discussions with potential lenders and other strategic alternatives, which may include public and private debt facilities, strategic alliances, partnerships, joint ventures, and other strategic alternatives.  Osisko will only provide updates on any such alternatives that advance to the point of requiring disclosure.  There can be no assurances that any such arrangements can be agreed on terms acceptable to Osisko.

The recently announced “bought-deal” private placement financing (please see Osisko news release dated February 6th, 2023) is expected to close on February 28th.
