SolGold plc

("SolGold" or the "Company")

Delivers Transformational Progress in 2025 &

Builds Momentum into 2026

The Board of Directors of SolGold (LSE: SOLG) is pleased to report a year of transformational progress, highlighted by a US$750 million stream financing, the acceleration of the Cascabel Feasibility Study, the completion of the Project Execution Plan, and the establishment of the ExploreCo strategy. Since year-end, the Company has drawn the second tranche of stream funding and advanced early works planning, rapidly building on the foundation established in the previous fiscal year.

The Company ended fiscal 2025 with a cash balance of US$11.8 million, and has since strengthened its position with a further US$33.3 million drawdown under the Franco-Nevada (Barbados) Corporation and OR Royalties International Ltd. (formerly Osisko Bermuda Limited) stream agreement ("Stream Agreement").¹

The Annual Report and Accounts for the year ended 30 June 2025 are available on the Company's website at www.solgold.com.

2025 Highlights

·      US$750 million Stream Financing: Closed Stream Agreement, securing pre-construction and partial construction funding (subject to conditions) while preserving all copper and silver, and a large majority of gold upside.¹

·      Cascabel Development: G Mining Services advanced the Feasibility Study, Early Works and Project Execution Plan, prioritising early open-pit production at Tandayama-América to accelerate first cash flow and de-risking the pathway to near-term cash flow and Alpala's long-life underground mine.²

·      ExploreCo Strategy: Announced the strategy to launch a separate exploration entity to unlock hidden value from SolGold's regional concessions; considered some of the most prospective properties globally, anchored by Porvenir.³

·      Porvenir Licence Secured: Environmental licence approved, enabling advanced technical studies, additional drilling, and a Preliminary Economic Assessment.⁴

·      Strategic Investment: Jiangxi Copper increased its stake to 12.2% with a US$18.1m investment at a 45% premium.⁵

·      Leadership Reset: Reset Board and Management with the appointments of CEO Dan Vujcic, Non-Executive Chairman Paul Smith, and Senior Independent Director Charles Joseland to drive the transition from explorer to developer.^{3, 6}

Comment from the Chief Executive Officer, Dan Vujcic:

"2025 reshaped SolGold. We secured transformational financing, accelerated development at Cascabel, and formulated the pathway for ExploreCo. Since year-end, we've drawn an additional US$33 million under the stream and advanced early works forward, underscoring the pace of progress and delivery. With Cascabel ranked among the world's largest undeveloped copper-gold projects and positioned in the bottom quartile of costs, SolGold is uniquely placed to deliver a tier one asset at a time when global demand for copper is surging. This progress is good for our shareholders, good for Ecuador, and vital for the responsible supply of copper the world needs."

Building on Momentum: FY2026 Initiatives

·    Break ground at Cascabel for the portal and declines in 2025.

·    Advance permitting and early works to align with construction readiness.

·    Complete the Cascabel Feasibility Study by mid-2026, paving the way for construction.

·    Secure remaining project financing and progress further stream drawdowns to fund development.

·    Position ExploreCo for a potential market debut to unlock exploration value for shareholders.
