PERTH, Australia and TORONTO, April 27, 2025 (GLOBE NEWSWIRE) — Alkane Resources Limited (ASX: ALK) (“Alkane”) and Mandalay Resources Corporation (“Mandalay”) (TSX: MND, OTCQB: MNDJF) are pleased to announce that they have agreed to combine in a “merger of equals” transaction and have executed a definitive arrangement agreement (the “Arrangement Agreement”) whereby Alkane will acquire all the issued and outstanding common shares of Mandalay pursuant to a court-approved plan of arrangement (the “Transaction”). Following completion of the Transaction, the combined company will continue operating as “Alkane Resources”, remain listed on the ASX and is seeking a listing on the TSX exchange.

Under the Transaction, Mandalay shareholders will receive 7.875 ordinary shares of Alkane for each ordinary share of Mandalay (the “Exchange Ratio”) held immediately prior to the effective time of the Transaction (the “Effective Time”). Upon completion of the Transaction, former Mandalay shareholders and existing Alkane shareholders will own approximately 55% and 45%, respectively, of the outstanding ordinary shares of the combined company, on an undiluted basis⁴. The implied market capitalization of the combined company is estimated at A$1,013 / C$898 million³. The executive team of the combined company will be Australian-based and led by Alkane Managing Director Nic Earner, an established executive with deep operational, management and corporate experience.

Alkane and Mandalay will host a joint conference call and webcast today, April 28, 9:30 am Sydney / April 27, at 7:30 pm Toronto. Details provided below.

The Transaction will create a diversified Australian centric gold and antimony producer with a portfolio of three operating mines and a strong balance sheet. Alkane’s established Tomingley gold mine (Australia), currently ramping up after a major capital expansion, will complement the well-established and stable production from Mandalay’s Costerfield underground gold/antimony mine (Australia) and the Björkdal underground gold mine (Sweden).

Strategic Rationale for the Transaction

• Combined forecast production of ~160,000¹ gold-equivalent ounces in 2025, growing to over ~180,000² gold-equivalent ounces in 2026.   The combined company will operate three producing mines in premier jurisdictions – Costerfield and Tomingley in Australia and Björkdal in Sweden. The combined company’s margins are expected to expand with 2025 AISC of ~A$2,750 / ~US$1,760³ per ounce reducing to approximately ~A$2,160 / ~US$1,420 per ounce in 2026.⁵
• Improved capital market positioning anticipated to drive valuation re-rate. The combined company is expected to benefit from a primary ASX listing valuation re-rate driven by GDXJ and potential ASX 300 index inclusion. Further value should be unlocked through greater trading liquidity, a larger free-float and a more diverse shareholder base as the combined company continues to grow.
• Creates a powerful platform with a shared vision for continued growth. Robust balance sheet with a proforma cash balance of A$188 / C$167 million³ at 31 March 2025 to pursue organic and inorganic growth. The combined company plans to continue to invest in exploration at all three of its producing mines and pursue other growth opportunities in addition to the Boda-Kaiser copper-gold project which adds future production potential with its significant scale.
• Merged leadership focused on delivering re-rate and driving growth. The combined company’s Board of Directors will consist of three Mandalay nominees (Brad Mills, Frazer Bourchier and Dominic Duffy), two Alkane nominees (Ian Gandel and Nic Earner) and a new independent Chair, Andy Quinn, a chartered mining engineer and highly credentialed investment banking and mining industry veteran. Management, led by Nic Earner, and including Mandalay’s operating team, provides operational continuity and foundation to unlock portfolio value.

Nic Earner, Managing Director of Alkane, commented: “The Transaction will take Alkane to a new level, bringing together two companies with complementary assets and a shared vision for growth. Mandalay’s two high-quality mines match the attributes of Tomingley: a proven history of consistent production, cash generation and exploration upside. The combination of assets, leadership, and supportive long-term shareholders enhances our scale and financial strength, and positions us well to continue to pursue additional growth opportunities”.

Frazer Bourchier, President and CEO of Mandalay, commented: “The Transaction presents a compelling opportunity for Mandalay shareholders to accelerate value creation through increased capital markets scale, liquidity and a growing diversified asset base. We are excited to have found a like-minded partner committed to the same principles. The Transaction aligns with our vision to create a mid-tier gold and antimony producer with mines in premier operating jurisdictions and with our strategy for continued growth. I am also pleased to have gained support of our major shareholders, as we believe the combined company will be extremely well positioned for a valuation re-rate in line with ASX-listed peers, and for subsequent growth”.

Benefits for Shareholders

• Diversified production from three mines in premier jurisdictions reduces overall operational and financial risk.
• Larger equity free-float and greater trading liquidity driven by anticipated increase in institutional and passive index investment.
• Valuation expected to re-rate to higher ASX-listed gold mining company multiples.
• Mandalay shareholders expected to benefit from Tomingley gold mine production and the growth potential of the large Boda-Kaiser copper-gold project.
• Alkane shareholders expected to benefit from exposure to strategic antimony production from Costerfield and combined company’s strengthened balance sheet.

Non-IFRS Performance Measures

This news release may contain references to gold equivalent produced and all-in sustaining cost all of which are non-IFRS measures and do not have standardized meanings under IFRS. Therefore, these measures may not be comparable between the companies or to similar measures presented by other issuers.

For Mandalay, all-in sustaining cost per ounce gold equivalent equals the sum of cash operating costs associated with the production of gold equivalent ounces at all operating sites in the period plus corporate overhead expense in the period plus sustaining mining capital, royalty expense, accretion of reclamation provision and tailings dam amortization, divided by the total gold equivalent ounces produced in the period.

For Alkane, all-in sustaining costs include total cash operating costs, sustaining mining capital, royalty expense, accretion of reclamation provision and tailings dam amortization. Sustaining capital reflects the capital required to maintain a site’s current level of operations. All-in sustaining cost per ounce of gold equivalent in a period equals the all-in sustaining cost divided by the equivalent gold ounces produced in the period.
