Software-first minerals company supplying critical materials for energy, AI, and defense
Mariana Minerals operates a vertically integrated minerals business built on software infrastructure rather than traditional extraction playbooks. The tech stack reveals a hybrid engineering organization: CAD/design tools (Autodesk, Civil 3D, Revit, Navisworks) dominate for greenfield construction and plant design, while Python, PyTorch, TensorFlow, and emerging LLM integration signal AI-driven optimization of chemical processes and supply-chain visibility. The hiring surge (74 roles in 30 days, heavily skewed toward senior engineers and interns) paired with documented pain around data integration and scaling pilot plants to commercial production suggests they're building operating-system-level software to automate mineral processing, not just buying off-the-shelf mining tools.
Mariana Minerals is a privately held minerals company based in San Francisco that combines traditional extraction and refining with software-first operations. They focus on sourcing minerals critical to modern energy, AI, and defense sectors. The business is vertically integrated—from greenfield mining operations (evidenced by geotechnical instrumentation and slope-stability project work) through chemical refining and plant optimization. Active projects span automation of mineral processing facilities, capital project execution software, and LLM-powered data integration, indicating they are building internal software capabilities alongside physical assets. Current scale is 51–200 employees across engineering, operations, HR, construction, legal, and manufacturing.
Mariana Minerals is developing first-of-its-kind chemical refining processes, automated plant optimization software, and an operating system for mineral processing facilities. Active projects also include greenfield copper-ore construction, geotechnical monitoring, and LLM integration for supply-chain data.
Mariana uses CAD and design tools (Autodesk, Civil 3D, Revit, Navisworks, Bluebeam), simulation software (ASPEN Plus, HYSYS, ETAP), Python, MATLAB, PyTorch, TensorFlow, React, and LLM frameworks. Manufacturing-side tooling includes ICP-OES and ICP-MS for analytical work.
