Atlantico Energy Metals mapped 12 rare earth-led target zones plus gallium and lithium targets at its Novo Cruzeiro project in Brazil, with gallium present in every one of 114 samples tested.
At a glance
- Atlantico Energy Metals identified 12 rare earth-led target areas plus separate gallium and lithium targets at its Novo Cruzeiro project in Minas Gerais, Brazil.
- Gallium was detected in all 114 surface samples collected, at grades of 16-72 ppm.
- 96 of 114 samples, mostly in the western Rio Bravo zone, returned total rare earth oxide grades above 500 ppm; one stream-sediment sample hit 1,427 ppm TREO.
- Eastern targets are supported by neodymium, praseodymium, dysprosium and terbium anomalies -- the elements used in permanent-magnet motors.
What happened
Canadian junior explorer Atlantico Energy Metals Corp. (CSE:ATLA, FRA:1CJ1) said on September 21 that an integrated review of its Novo Cruzeiro project in Brazil has defined 12 rare earth-led target areas alongside separate gallium and lithium targets, across more than 24,000 hectares of contiguous claims in Minas Gerais state's so-called Lithium Valley. The review combined geochemical sampling, reconnaissance mapping, satellite imagery and geophysics gathered over recent months. Gallium turned up in all 114 surface samples collected, at grades of 16 to 72 parts per million (ppm) -- a result the company first disclosed in March 2026 and has now folded into a formal target map. Ninety-six of those 114 samples, concentrated in the project's western zone near Rio Bravo, returned total rare earth oxide (TREO) grades above 500 ppm, and one stream-sediment sample came back at 1,427 ppm TREO, including 284 ppm of mixed rare earth oxide. Eastern target areas are backed by neodymium and praseodymium anomalies alongside dysprosium and terbium indicators -- the four elements most central to permanent magnets used in EV motors and wind turbines. A separate lithium target in the south of the property returned a maximum pathfinder intercept of 71 ppm, which the company is treating as a geological and geophysical case for drill-testing rather than a confirmed lithium discovery. "We're definitely looking at a multiple discovery package potentially across the critical minerals spectrum," said Atlantico president and CEO Bonn Smith, adding that the target areas provide "several compelling avenues for exploration." The company's next step is a maiden drilling programme on priority targets, alongside continued examination of artisanal mine workings on the property to better understand the underlying pegmatite geology.
The details
What makes Novo Cruzeiro notable isn't any single number in Atlantico's release -- it's that three separate critical minerals turned up enriched across the same land package. Gallium appearing in literally every one of 114 samples is an unusually consistent signal for an early-stage exploration project; most target-generation programmes are lucky to get a scattered handful of anomalous hits, not a clean sweep. Rare earth oxide grades above 500 ppm in 96 of those same samples, plus a standout 1,427 ppm stream-sediment result, point to real enrichment worth chasing with a drill bit rather than a one-off geochemical fluke.
None of this is a resource yet, and the distinction matters. Sixteen to 72 ppm gallium and a 71 ppm lithium pathfinder intercept are geochemical signals used to rank where to drill next, not grades a mine could be built around -- Atlantico itself is treating the lithium result as a geological and geophysical case for testing, not a discovery. The company has no NI 43-101 resource estimate, no confirmed intercepts at depth, and years of derisking ahead of it before Novo Cruzeiro could plausibly become a producing asset. That gap between target and mine is exactly why the announcement is framed around exploration -- a maiden drill programme, not a construction decision.
The timing still matters beyond the rock itself. China controls roughly 90% of global rare earth processing capacity and around 98% of refined gallium output, and Beijing has restricted gallium exports since August 2023 -- a policy backdrop that has pushed governments and manufacturers in the US, Europe and elsewhere to actively seek supply outside China, even from early-stage sources. Brazil's Jequitinhonha Valley, the district Novo Cruzeiro sits in, is already known internationally as a lithium hub -- Sigma Lithium's producing Grota do Cirilo mine sits in the same valley -- but a project targeting rare earths and gallium alongside lithium in one district is a less common combination. That's what gives Atlantico's target map a strategic hook even at this early a stage: three minerals on China's most-watched critical-minerals list, co-located on one 24,000-hectare package, in a jurisdiction with existing lithium infrastructure and mining know-how nearby.
Why it matters
Gallium and rare earths get relatively little coverage against gold, silver or copper, even though both sit near the center of the China-dependence debate reshaping semiconductor and EV magnet supply chains. A junior explorer finding gallium in every sample it has tested, and rare earth enrichment in most of them, across a single Brazilian project is a genuine early data point in the search for supply outside China -- worth tracking for MetalsCost readers watching where the next non-China gallium or rare earth source might eventually come from, even though a maiden drill programme is still ahead.
Our read
Outlook: neutral. This is target-generation news from a single junior explorer at the pre-drilling stage -- a genuinely positive signal for the company's own prospects and for the broader non-China supply-diversification narrative, but not something that moves current spot gallium or rare earth prices, which remain governed by Chinese production and export policy.
What to watch
- Assay results and any NI 43-101 technical disclosures from Atlantico's planned maiden drilling programme
- Further exploration updates on the southern lithium target and its pegmatite context
- CSE:ATLA trading volume and financing announcements tied to funding the drill programme
- Broader government critical-minerals policy developments affecting non-China gallium and rare earth projects

Detailed analysis
Timeline
- 2026-03: Atlantico first disclosed gallium and rare earth detections in all 114 follow-up surface samples at Novo Cruzeiro.
- 2026-09-21: Atlantico released an integrated exploration review defining 12 rare earth-led target areas plus separate gallium and lithium targets.
Supply Drivers
Atlantico's target-generation results at Novo Cruzeiro represent an early-stage step toward a potential new, non-China source of gallium, rare earth oxides and lithium, contingent on a still-unstarted maiden drilling programme confirming grades at depth.
Government Policies
Governments in the US, EU and elsewhere have been actively supporting critical-minerals supply diversification away from China, a backdrop that makes early-stage gallium and rare earth exploration outside China strategically relevant even before a project reaches production.
Geopolitical Risks
China controls roughly 90% of global rare earth processing capacity and around 98% of refined gallium output, and has restricted gallium exports since August 2023 -- the central reason non-China gallium and rare earth targets like Novo Cruzeiro draw strategic attention despite being at an early exploration stage.
Mining Production
Novo Cruzeiro remains at the target-generation stage -- 12 rare earth-led target areas plus gallium and lithium targets defined from surface sampling and geophysics, with a maiden drilling programme still to come before any resource can be estimated.
What could lift prices
- Gallium present in all 114 samples tested is an unusually consistent enrichment signal for an early-stage exploration project.
- 96 of 114 samples exceeding 500 ppm total rare earth oxide, including one 1,427 ppm result, suggests genuine mineralized enrichment rather than scattered anomalies.
- Three separate critical minerals -- gallium, rare earths and lithium -- co-occurring on one land package diversifies the project's discovery potential beyond a single commodity.
What could weigh on prices
- All results so far are surface geochemical samples and pathfinder anomalies, not drill-confirmed grades -- Novo Cruzeiro has no resource estimate of any kind.
- The cited lithium intercept of 71 ppm is well below what would typically justify calling it a discovery; the company itself describes it as a target to test, not a confirmed find.
- Junior exploration equities carry high stock-specific risk and are exposed to dilution from the financing a maiden drilling programme will require.
Country impact
| Country | Impact | Reason |
|---|---|---|
| Brazil | Medium | Novo Cruzeiro sits in Minas Gerais state's Jequitinhonha Valley, already known as Brazil's Lithium Valley, and a confirmed multi-commodity discovery there would add rare earths and gallium to the district's existing lithium profile. |
| Canada | Low | Atlantico Energy Metals is a Canadian company listed on the Canadian Securities Exchange, so exploration success at its Brazilian project would primarily benefit Canadian-listed shareholders. |
| China | Medium | As the dominant supplier of refined gallium and processed rare earths, China is the incumbent that non-China exploration projects like Novo Cruzeiro are implicitly positioned against, though any competitive effect remains years away. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Mining Exploration | Positive | A clean multi-commodity target map across gallium, rare earths and lithium gives Atlantico a stronger basis to justify and fund a maiden drilling programme. |
| Semiconductor Manufacturing | Positive | Any future non-China gallium supply would benefit chipmakers currently dependent on Chinese-refined gallium for compounds like gallium arsenide and gallium nitride. |
| Electric Vehicle Manufacturing | Positive | Neodymium, praseodymium, dysprosium and terbium enrichment at the eastern targets points toward potential future magnet-metal supply for EV motors, if confirmed by drilling. |
Who gains, who loses
- Atlantico Energy Metals shareholders: A well-defined, multi-commodity target map strengthens the case for financing and executing a maiden drilling programme, the next value-adding step for a junior explorer.
Other ways this could play out
- If the maiden drilling programme confirms economic grades at depth across multiple target areas, Novo Cruzeiro could advance toward a formal resource estimate and a significant re-rating for Atlantico.
- If drilling fails to confirm the surface anomalies at depth, the project could remain at target-generation stage indefinitely, as happens with the large majority of junior exploration properties.
Price risks
- Negative or inconclusive drill results would be a stock-specific risk for Atlantico rather than a broader gallium or rare earth market risk, since the project remains pre-resource.
- Spot gallium and rare earth prices continue to be set mainly by Chinese production and export-policy decisions, which this early-stage exploration news does not change.
Historical comparison
- Since 2023: Brazil's Jequitinhonha Valley ("Lithium Valley") in Minas Gerais has drawn multiple lithium-focused explorers and producers, including Sigma Lithium's operating Grota do Cirilo mine, though Atlantico's project is among the few in the district explicitly targeting rare earths and gallium alongside lithium.
