Last week, our senior management team visited the #Warintza Project in #Ecuador, engaging directly with host communities and reaffirming our commitment to transparent, respectful, and inclusive dialogue. The team met with community members to listen, share updates, and collaborate on our shared vision for Warintza’s future. We also held a productive meeting with Ecuador’s Vice Minister of Mining, Javier Subia, discussing amongst other topics, the positive advancement of the Environmental Impact Assessment (EIA). These engagements reflect our belief that a strong social license to operate is built on trust, mutual respect, and shared value. Warintza is not a short-term initiative, but a long-term partnership with Ecuador, one with the potential to uplift communities, preserve biodiversity, and contribute to national development. As we move forward, we remain committed to open dialogue, genuine partnership, and creating a legacy of collective progress for future generations.

The Development Imperative – Advancing Copper Responsibly (4 of 4) The energy transition can’t happen without #copper—and copper can’t be delivered without responsible development. Exploration is only part of the solution. To close the looming supply gap, the world needs de-risked, scalable, and socially aligned copper projects—and it needs them urgently. This is where #Solaris Resources stands apart. Our flagship #Warintza Project in #Ecuador offers: Tier 1 scale, strip ratio profiling and grade A strong social license built through genuine and lasting community partnership A clear, low-risk development path in a supportive jurisdiction We are advancing a copper project built for the future—one that aligns with the global push for critical minerals, ESG leadership, and long-term value creation. If you’re following the copper story, now is the time to watch companies like Solaris that are actively building the future of supply. Let’s talk copper.

Price Pressure – Why the Market Is Waking Up (3 of 4) The #copper market is sending a clear message: scarcity is setting in. Global copper inventories are hovering near record lows, while demand—driven by electrification and green infrastructure—is rapidly accelerating. Prices are beginning to reflect signs of this structural mismatch. Many analysts now see the early stages of a new copper supercycle, with forecasts pointing to the metal price surpassing all-time highs in the coming years. In response, governments, automakers, and tech firms are scrambling to secure long-term supply. But with few large-scale projects advancing, high-quality, near-term development assets are emerging as strategic priorities. #Solaris Resources is exceptionally well-positioned. Our #Warintza Project combines scale, grade, and strong ESG fundamentals—the profile the market is beginning to reward in a supply-constrained environment. #Miningforthegoodofall

Copper Supply Crunch: The Elephant in the Mine (2 of 4) Demand is surging—but where will the new supply come from? According to leading market analysts, the #Copper industry is heading toward a major supply shortfall. Current mine supply approximates between ~22 -23 Mt per year however leading analysts have forecast demand surging to ~35 Mt per year by 2035 which is the equivalent of one new Escondida-sized mine every year for the next decade – a near-impossible task given long lead times. The problem? The current project pipeline is worryingly thin. Here’s why: • Long lead times — It takes 10–15 years to bring a discovery into production • Declining ore grades and aging, depleting mines • Underinvestment since the last commodity supercycle • Permitting complexity and evolving ESG expectations At #Solaris Resources, we’re proactively addressing these challenges through the advancement of Warintza—one of the most significant, high-quality, near-term, undeveloped copper projects in the Americas. Our exciting upcoming key milestones include: Technical approval of the Environmental Impact Assessment (EIA) expected this summer Pre-Feasibility Study (PFS) on track for Q3 2025 Responsible copper development isn’t just possible—it’s essential.

From Bellwether to Backbone (1 of 4) #Copper is no longer just an economic indicator—it’s the cornerstone of the global energy transition and essential to meeting the world’s decarbonisation goals. From electric vehicles, energy storage to renewable power and grid modernisation, copper demand is rising rapidly. The International Energy Agency (IEA) projects demand could double by 2035 as electrification efforts scale globally. Yet while demand surges, supply is falling behind. A lack of new, large-scale copper development projects has created a structural shortfall the market is only beginning to confront. At #Solaris Resources, we believe closing this gap starts with responsibly advancing high-quality, near-term copper assets—like our flagship #Warintza Project in #Ecuador.

We’re pleased to share an extended interview with our CEO, Matthew Rowlinson, providing in-depth insights into our recently announced US$200 million financing agreements. This is a pivotal moment for #Solaris as we advance the development of our #Warintza #copper project — a critical tier 1 asset aligned with the global energy transition. In the interview, Matthew Rowlinson discusses: ✅ Key terms of the non-dilutive financing agreements ✅ The background to the deal and how the funds will take Solaris through to a FID ✅ Retaining exposure to significant exploration upside potential ✅ Warintza’s position as a multi-generational tier 1 copper project following significant due diligence 📺 Watch the full interview here: bit.ly/43g98HJ We thank our investors and stakeholders for their continued support as we move forward with confidence and momentum. #Miningforthegoodofall

Solaris Resources enters into US$200 million financing agreements with Royal Gold Non-dilutive US$200 million funding package from Royal Gold, comprising a gold stream and NSR royalty, US$100 million of which is available immediately Provides the funding required to repay the Senior Debt facility and the necessary liquidity to fund all value accretive derisking activities through to a final investment decision Stream expected to represent a small percentage of the gold over the life of mine which, together with the modest NSR royalty, reinforces Warintza’s position as a multi-generational tier 1 copper project Stream termination provision contains no penalties under a change-of-control scenario, providing the Company flexibility to enhance shareholder value going forward Maintained strategic optionality around future project financing Funding package restricted to Warintza cluster thus retaining exposure to significant exploration upside potential with commercial optionality around high-priority targets within the Warintza district #Warintza #Ecuador #Solaris

“I am a woman, I am Shuar, and I am proud to be the voice of all women who dream of a future beyond what we have been told is possible”– Angie Tsuink, Solaris scholarship coordinator. #SLS was proud to host a delegation of community leaders from the #Warintza Project at #PDAC2025 earlier this week where Angie Tsuink presented at the Ecuadorian #womeninmining event. In her speech she spoke about how Solaris believes that education is the engine of sustainable growth. By providing access to education, we are laying the foundations for conscious and responsible action, contributing to community development, strengthening relationships of trust and ensuring the long-term success of the project. Angie also noted the 77 scholarships awarded to date and why Solaris believes that prioritizing women's education helps to promote equity and community well-being, generating a positive impact on social, economic and environmental sustainability. Today on #InternationalWomensDay , we celebrate the achievements of women in mining and reaffirm our commitment to driving educational opportunities, promoting gender equity and women’s economic empowerment. Together, we continue to create a vision for mining that uplifts our communities, respects our land, and lays the foundation for a brighter future for all Ecuadorians. #Miningforthegoodofall

#SLS Resources announces the formation of an Inter-Institutional working group together with PSHA, ratified through the signing of a LOI. As an influential indigenous organisation operating in Morona Santiago, outside of our direct area of influence, this important step forward highlights the fundamental progress the Company has made through embracing an open dialogue and partnership rooted in trust, understanding, and mutual respect, encompassed within the #Warintza participatory mining model. Matthew Rowlinson, President and CEO commented, “At Solaris Resources, we believe that sustainable mining is not just an economic endeavour; it is a journey that must include the insights and values of every stakeholder involved, especially our indigenous populations. Their lived experiences and deep connection to the land are vital to shaping responsible mining practices that respect both our natural environment and cultural heritage. As we move forward, its vital we embrace an open dialogue and partnership rooted in trust, understanding, and mutual respect. “Together, we continue to create a model for mining that not only drives economic growth but also uplifts our communities and preserves the rich tapestry of the Ecuadorian culture. “Thanks to the Pueblo Shuar Arutam organization, and all other stakeholders, for their trust and support as we look to sustainably deliver this Tier 1 asset. This project is for Ecuador, by Ecuador and for the benefit of all stakeholders today, and the generations to come.” To learn more, please click on the following link: bit.ly/3D51jKR #Miningforthegoodofall
