Star Metro - SolGold PLC Announces Environmental Licence Granted for Porvenir Project

BISHOPSGATE, LONDON / ACCESS Newswire / May 12, 2025 / SolGold (LSE:SOLG)(TSX:SOLG) is pleased to announce that the Government of Ecuador has granted the Environmental Licence ("Licence") for the Porvenir Project ("Porvenir" or the "Project"), located in southern Ecuador's Zamora Chinchipe province. The concessions that comprise the Project are held by Green Rock Resources S.A., SolGold's 100%-owned Ecuadorian subsidiary.

The Licence, issued under Resolution MAATE-SCA-2025-0012-R by the Ministry of Environment, Water and Ecological Transition ("MAATE") and supported by a phase change declaration to the Advanced Exploration Phase from the Ministry of Energy and Mines, authorises SolGold to undertake a comprehensive suite of advanced-stage exploration activities. These include diamond drilling, trenching, geotechnical investigations, hydrogeological and metallurgical studies, and other related field programs to support Project development.

The Licence covers all four Porvenir Project concessions, totalling 5,261 hectares. This includes the Cacharposa deposit and nearby porphyry targets such as Diablo, Mula Muerta, Eudis, Barolo, Pamal, and Balmore. Project development activities will proceed under Ecuador's gran minería (large-scale mining) regime, which governs the development of projects with significant scale and long-term potential.

The approval comes following the successful completion of the Environmental Impact Study and a constructive public consultation process. Local stakeholders expressed support for continued exploration at Porvenir, recognising its potential to bring long-term employment and economic development. SolGold's established presence in the region, commitment to hiring and training local workers, and strong environmental practices have helped to foster a collaborative, forward-looking relationship with surrounding communities.

PRELIMINARY ECONOMIC ASSESSMENT IN PROGRESS

SolGold is finalising its internal technical and economic studies, which it will share, with the necessary caveats, with the market when complete. In parallel, the Company is in the process of engaging an independent engineering firm to complete a Preliminary Economic Assessment ("PEA") for the Porvenir Project. The study will integrate updated geological modelling, the most recent drilling data, and more current market assumptions - including revised metal prices and operating cost frameworks. The PEA will evaluate both open-pit and potential underground mining scenarios, as well as low-cost bulk mining methods suited to the system's scale and geometry.

Dan Vujcic, CEO of SolGold, commented:

"This licence allows us to advance Porvenir, the cornerstone asset of ExploreCo, into its next phase with momentum. The Company has an exciting portfolio of tenements in the southern part of the country, a region which consists of top-tier success stories, namely Fruta de Norte and Mirador. We're excited to build on the solid geological foundation already demonstrated at Cacharposa and take a technically driven look at how best to achieve its significant potential and to see its value acknowledged in our share price. Over the coming weeks, site visits will be conducted, allowing us to fully evaluate all options and the optimum path forward. The strong support of our Ecuadorian team and local communities has made this possible, and we're ready to move forward."

STRATEGIC CONSIDERATIONS

The Porvenir asset will be the cornerstone asset in SolGold's ExploreCo portfolio. The Company is currently evaluating the capital requirements to continue developing Porvenir, as well as maintaining ongoing discussions with potential ExploreCo partners and stakeholders.

ENVIRONMENTAL AND COMMUNITY COMMITMENT

As technical work advances, SolGold remains committed to sustainable development and responsible mining. All plans will continue to be guided by environmental responsibility, inclusive stakeholder engagement, and alignment with community values. This permitting milestone builds on SolGold's proven track record of progressing projects through Ecuador's regulatory framework.

CACHARPOSA: A LARGE, OPEN MINERAL SYSTEM^1,2,3

Note: The following information is based on previously released data and does not reflect updates from the PEA, which is currently in progress.

The Cacharposa deposit hosts a significant porphyry copper-gold system with near-surface mineralisation. The Cacharposa Mineral Resource Estimate ("CACMRE#1") (Porvenir Property NI 43-101 Technical Report Mineral Resource Estimate, 26 October 2021)¹ was defined using a dataset comprised of 18,635.7m of diamond drilling; 439.6m of surface rock-saw channel sampling from 23 outcrops; and 16,982.4m of final assay results from 20 drill holes.

The Mineral Resource Estimate (effective 26 October 2021) includes:

· Indicated Resource: 396.8 Mt @ 0.44% CuEq

· Inferred Resource: 96.9 Mt @ 0.37% CuEq
(at a 0.16% CuEq cut-off)

The copper equivalency factor of 0.632 (whereby CuEq (%) = Cu (%) + Au (g/t) x 0.632) is based on third-party metal price forecasts, estimated recoveries, and cost inputs based on data available from similar deposits.

Notes:

1. Dr Andrew Fowler, MAusIMM CP(Geo), Principal Geology Consultant of Mining Plus, is responsible for this Mineral Resource statement and is an "independent Qualified Person" as such term is defined in NI 43-101.

2. The Mineral Resource is reported using cut-off grades that are applied according to the mining method where 0.16 % CuEq applies to potentially open pittable material and 0.28 % CuEq applies to material potentially mineable by underground bulk mining methods. Copper equivalency is discussed in detail in "Reasonable Prospects for Eventual Economic Extraction",

3. The Mineral Resource is considered to have reasonable prospects for eventual economic extraction by open pit mining.

4. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

5. The statement uses the terminology, definitions and guidelines given in the CIM Standards on Mineral Resources and Mineral Reserves (May 2014) as required by NI 43-101.

6. Figures may not compute due to rounding.

A conceptual starter pit was previously modelled at 44 Mt @ 0.64% CuEq, highlighting potential for phased development.

Since the release of CAC MRE#1, SolGold has completed an additional 2,610m of infill and extension diamond drilling at Cacharposa, bringing the total to more than 21,200 metres. New drilling is planned to further test extensions of the mineralised system. A mineralised corridor approximately 1,200 metres long, 800 metres wide, and 1,000 metres vertically has been outlined. The deepest drill hole to date (PDH-20-002) reached 1,200 metres and terminated in mineralisation, indicating that the system remains open at depth.³
