Atlas Critical Minerals has published a maiden mineral resource estimate for its Malacacheta Graphite Project in Minas Gerais, Brazil. The estimate covers 24.2 million tonnes at a 2.0% graphitic carbon cut-off, including 17.2 million tonnes indicated at 5.73% Cg and 7.0 million tonnes inferred at 5.40% Cg. That works out to about 1.36 million tonnes of contained in-situ graphite across both categories. The company says it is the largest reported graphite resource in South America and that the indicated grade is roughly 25% higher than the grade at Graphite Creek in Alaska, the largest known US deposit. The resource is based on 21 diamond drill holes, all of which returned significant intercepts, with mineralization starting near surface in more than half of the holes. Only one of three contiguous tenements and about 2.5 kilometers of an 11 kilometer corridor have been drilled, so the deposit remains open along strike and at depth. Atlas plans to use the indicated resource as the basis for a preliminary economic assessment. Graphite from the project has already been qualified for use in EV batteries and nuclear reactors, though those results came from concentrate samples and do not yet represent a production plan.

First resource estimate for Atlas Critical Minerals' Malacacheta project in Brazil: 24.2 Mt at around 5.6% Cg, with 17.2 Mt indicated. That puts it in the conversation for Western graphite supply for EV and nuclear uses. Still early, no PEA yet, and the resource is in-situ, so recoverable tonnes will be lower. Worth watching if they move to economic studies.

Graphite is one of those materials where most processing still happens in China, so a new South American resource with decent grade matters for supply chain diversification. The 5.73% indicated grade compares well with Graphite Creek, but resource size alone doesn't fix the refining bottleneck. The missing detail is downstream plans, who would process this and where.

Near-surface, open pit amenable, all 21 holes hit mineralization. That part is solid. What I want to see is the PEA and what the strip ratio and energy costs look like. Graphite processing is power hungry, and Brazilian project economics will depend on grid access and local power prices, not just grade. Also only one of three tenements is counted, so upside is real but unproven.

Atlas Critical Minerals filed a maiden resource for its Malacacheta graphite project in Minas Gerais. The headline numbers: 17.2 Mt indicated at 5.73% Cg and 7.0 Mt inferred at 5.40% Cg, with around 1.36 Mt of contained graphite. Company says it is the largest reported graphite resource in South America. Drilling covered only 2.5 km of an 11 km corridor, so the deposit remains open.

Critical mineral policy keeps pushing for non-China graphite supply, and this adds data to that conversation. But an MRE is not a mine. The real test is whether the project clears permitting, gets power and water, and finds a buyer for concentrate. If US and EU incentive structures reward domestic processing, this kind of resource becomes more viable. Until then, treat it as exploration news.

Good to see a graphite resource outside China with real grade and near-surface mineralization. The 43.1 meter intercept at 6.2% Cg and the shallow high-grade hits suggest the deposit could be straightforward to develop. Still, the resource is only on one tenement and the PEA has not been released. Next update to watch for is the economic assessment.
