A new funding round will help expand copper and lithium projects while supporting the growing demand for minerals needed in clean energy and advanced technologies
San Francisco, California, 5 August 2026 – Mariana Minerals has secured US$310 million in Series B funding to accelerate development of its critical-minerals projects in the United States. The investment reflects the increasing importance of copper and lithium, two essential minerals used in electric vehicles, renewable energy systems, artificial intelligence infrastructure, and modern electronics. The funding will also support the expansion of the company’s technology-driven mining operations and strengthen domestic mineral production.
The latest investment brings Mariana Minerals’ total funding to approximately US$400 million. The company plans to use the capital to advance its flagship Copper One project in Utah and Lithium One project in Texas. These projects are expected to contribute to a stronger and more reliable supply of critical minerals that are increasingly needed for global industrial and energy development.
Demand for critical minerals has grown rapidly as countries and industries continue investing in electric mobility, renewable energy, data centers, and advanced manufacturing. Copper is widely used in power transmission, electric motors, and charging infrastructure, while lithium remains a key component in rechargeable batteries. As the transition toward cleaner technologies continues, securing a stable supply of these resources has become an important priority for manufacturers and infrastructure developers worldwide.
The mining industry is also embracing digital transformation to improve efficiency and reduce project timelines. Mariana Minerals combines mining, refining, and digital technologies to improve planning, construction, and operations. Advanced software, automation, and artificial intelligence are helping companies manage complex mining projects more efficiently while supporting safer and more sustainable production practices.
Industry experts believe that investment in critical minerals will continue to increase over the coming years as demand for clean energy technologies and advanced manufacturing expands. Companies that successfully combine resource development with innovation and operational efficiency are expected to play an important role in supporting future industrial growth and strengthening supply chains.
As global demand for copper, lithium, and other essential minerals continues to rise, investments in new mining projects and modern production technologies are expected to improve supply resilience while supporting long-term economic development. The latest funding for Mariana Minerals reflects the growing confidence in the future of critical minerals and their role in powering next-generation industries.
