Sirios Resources Inc. (TSXV: SOI,OTC:SIREF) (OTCQB: SIREF) (‘Sirios’) and OVI Mining Corp. (‘OVI’) are pleased to announce the completion of their previously announced business combination by way of a court approved plan of arrangement under the Business Corporations Act (British Columbia) (the ‘Transaction’). Under the Transaction, Sirios acquired all of the common shares of OVI (each, an ‘OVI Share’) outstanding immediately prior to the effective time of the Transaction, which resulted in OVI becoming a wholly-owned subsidiary of Sirios.

Following completion of the Transaction, each former holder of OVI Shares is entitled to receive 2.34 common shares of Sirios (each, a ‘Sirios Share‘) in exchange for each common share of OVI held immediately prior to the effective time of the Transaction.

Concurrent with the completion of the Transaction, Jean-Félix Lepage has been appointed Chief Executive Officer of Sirios, replacing Sirios founder, Dominique Doucet, who will transition to Executive Chairman and Head of Exploration. In addition, Sean Roosen and Laurence Farmer have joined the board of directors of Sirios (the ‘Board‘), adding deep Québec mining and capital markets expertise to the Sirios team.

Mr. Lepage has over 15 years of experience in mining and managing operations, projects, and development activities.

Mr. Lepage obtained his Bachelor of Mining Engineering from Université Laval and holds a college technical degree in mineral processing from CEGEP de Thetford.

Jean-Félix Lepage, incoming CEO of Sirios, stated: ‘I am honoured to lead Sirios Resources as we enter this exciting new chapter. The combination of Sirios and OVI creates a stronger, well-capitalized company with an exceptional portfolio of gold assets in the Eeyou Istchee James Bay region. I look forward to working with our talented team and newly strengthened board to advance our exploration and development programs and deliver value for our shareholders.’

Dominique Doucet, former CEO of Sirios, stated: ‘After founding and leading Sirios for many years, I am proud to see the company take this significant step forward. This transaction brings together two complementary teams and asset portfolios, strengthening our position in the James Bay gold camp. In my new role as Executive Chairman and Head of Exploration, I remain deeply committed to Sirios and look forward to focusing my efforts on advancing our exploration programs and supporting Jean-Félix and the team in building on the foundation we have established.’

The Board is led by Executive Chairman Dominique Doucet, and now includes Sean Roosen and Laurence Farmer, as well as Robert Ménard, Colinda Parent and Guy Le Bel. Luc Cloutier has resigned from the Board. Sirios would like to express its sincere gratitude for his years of service.

Luc’s contributions have left an lasting mark on Sirios, and his legacy will continue to shape our path forward. On behalf of the entire Sirios team, we extend our heartfelt appreciation and wish him every success in his future endeavours.’

Mr. Roosen is the founder and Executive Chairman of Osisko Development Corp., and former CEO of OR Royalties Inc. As founder, President, Chief Executive Officer, and Director of Osisko Mining Corporation, Mr. Roosen was responsible for developing the strategic plan for the discovery, financing, and development of the Canadian Malartic mine. Recognized as one of the ‘Top 20 Most Influential Individuals in Global Mining,’ in 2017, he brings unmatched industry vision and strategic leadership.

Mr. Farmer is the General Counsel and VP Strategic Development of Osisko Development Corp. and the Chief Executive Officer of Electric Elements Mining Corp., prior to which he was Senior Counsel of OR Royalties Inc. Prior to joining the Osisko Group, Mr. Farmer worked in investment banking at RBC Capital Markets in London and, before that, practiced as a corporate lawyer with Norton Rose Fulbright LLP in London, England and Montréal, Canada, and brings strong transactional expertise and strategic insight into global resource development.

Toronto, Ontario TheNewswire – February 27, 2026 Juggernaut Exploration Ltd. (TSX-V: JUGR) (OTCPK: JUGRF) (FSE:4JE) (the ‘Company’ or ‘Juggernaut’) is pleased to announce that it has entered into an agreement with Stifel Canada (the ‘Underwriter’) to act as sole bookrunner and underwriter in connection with a ‘bought deal’ private placement offering by the Company of 3,906,250 units of the Company (the ‘Units’) at an issue price of

$2.56 per Unit (the ‘Offering Price‘), for aggregate gross proceeds of $10,000,000 (the ‘Offering‘). Each Unit will be comprised of one common share (a ‘FT Share‘), and one-half of one common share purchase warrant (each whole warrant, a ‘Warrant‘). Each Warrant shall entitle the holder thereof to purchase one common share in the capital of the Company at an exercise price of $2.08, for a period of 24 months following the Closing Date (as defined below). The FT Shares and Warrants are intended to qualify as ‘flow-through shares’ as defined in subsection 66(15) of the Income Tax Act (Canada) (the ‘Tax Act‘).

The Company has granted the Underwriter an option to sell such number of additional Units as is equal to 15% of the number of Units sold under the Offering at the Issue Price (the ‘Underwriter’s Option‘). The Underwriter’s Option will be exercisable, in whole or in part, at any time up until 48 hours prior to the closing date of the Offering (the ‘Closing Date‘).

The Offering is expected to close on or about March 19, 2026, and is subject to certain conditions including the receipt of all necessary approvals such as the approval of the TSX Venture Exchange (the ‘Exchange‘).

The gross proceeds from the Units will be used to incur exploration expenses that qualify as ‘Canadian exploration expenses’ as defined in subsection 66.1(6) of the Tax Act, ‘flow-through critical mineral mining expenditures’ as defined in subsection 127(9) of the Tax Act for purposes of the mineral exploration tax credit, and for individual subscribers of Units that are resident in British Columbia, ‘BC flow-through mining expenditures’ as defined in subsection 4.721(1) of the Income Tax Act (British Columbia) (the ‘Qualifying Expenditures‘) on the Company’s flagship Big One Gold Project, located in British Columbia, Canada. Such expenses will be incurred on or before December 31, 2027, and renounced to the subscribers with an effective date no later than December 31, 2026.

In connection with the Offering, certain purchasers of Units intend to subsequently (i) donate some or all of such Units to registered charities, who may sell such Units to purchasers arranged by the Underwriter, and/or (ii) sell some or all of such Units to purchasers arranged by the Underwriter, in each case on the Closing Date (such Units described in (i) and (ii), being the ‘Re-Offer Units‘). Sales of Re-Offer Units may be made to purchasers located in (i) each of the provinces of Canada, other than Quebec, pursuant to the Listed Issuer Financing Exemption (as defined below), (ii) the United States pursuant to available exemptions from the registration requirements of applicable United States securities laws, and (iii) such other jurisdictions provided it is understood that no prospectus filing or comparable obligation, ongoing reporting requirement or requisite regulatory or governmental approval arises in such other jurisdictions

Subject to compliance with applicable regulatory requirements and in accordance with National Instrument 45-106 – Prospectus Exemptions (‘NI 45-106‘), the Units will be offered for sale to purchasers resident in Canada

and/or other qualifying jurisdictions pursuant to the listed issuer financing exemption under Part 5A of NI 45-106 (the ‘Listed Issuer Financing Exemption‘). As the Offering is being completed pursuant to the Listed Issuer Financing Exemption, the securities underlying the Units issued pursuant to the Offering will not be subject to a hold period pursuant to applicable Canadian securities laws. There is an offering document related to the Offering that can be accessed under the Company’s issuer profile on SEDAR+ at www.sedarplus.ca and on the Company’s website at juggernautexploration.com. Prospective investors should read the offering document before making an investment decision.

In consideration for the services provided to the Company in connection with the Offering, the Underwriter will be entitled to receive a cash commission equal to 6.0% of the gross proceeds raised under the Offering (the ‘Cash Commission‘) and such number of broker warrants (‘Broker Warrants‘) as is equal to 6.0% of the number of Units sold under the Offering (including the Underwriter’s Option). Each Broker Warrant will entitle the holder thereof to acquire one common share of the Company at a price of C$1.81 for a period of 24 months following the closing date of the Offering. For the avoidance of doubt, the Cash Commission will be paid from the Company’s cash on hand and not from the gross proceeds received by the Company under the Offering.
