Mariana Minerals

Mariana Minerals is transforming the critical minerals industry by becoming the world's first software-first, vertically integrated minerals company. Traditional mining projects take 12 years from discovery to production - far too slow to meet the exploding demand from clean energy, AI infrastructure, and defense technologies. Mariana exists to fix this bottleneck. By combining deep mining expertise with advanced software, machine learning, and automation, the company shrinks development timelines while lowering costs and improving environmental performance.

Backed by Andreessen Horowitz and led by a team with experience from Tesla, Palantir, and the mining industry, Mariana is actively building and operating projects across the United States. Their Lithium One facility is the world's first GWh-scale commercial lithium extraction operation using oil and gas produced water, while Copper One represents the first autonomy-first copper mine and refinery. The company's proprietary PlantOS platform uses reinforcement learning - the same technology powering self-driving vehicles - to autonomously control mineral processing operations in real time. Mariana's goal is ambitious: deliver 10 critical mineral projects in 10 years, helping secure a domestic supply chain for the technologies powering America's future.
