AI Data Centers Are Being Rewired. One Critical Metal Is Moving With Them

Minas Gerais, Brazil, September 3rd, 2026, FinanceWire

Artificial intelligence has spent the past several years turning chips into infrastructure. Now the infrastructure around those chips is changing too.

The problem is power. Electricity entering a data center can pass through several conversions before it reaches the processor, and each one adds losses, equipment and complexity. As AI racks move toward megawatt-scale power requirements, the industry is redesigning that path around 800-volt direct current (VDC). The shift is already moving from engineering diagrams into commercial hardware, and one critical metal is showing up inside the new architecture: gallium.

Spark Energy Minerals Inc. (CSE: SPRK) (OTCPK: SPARF) (FSE: 8PC) is exploring for that metal alongside rare earths and scandium at its approximately 91,900-hectare Arapaima Project in Minas Gerais, Brazil. Forty-two reverse-circulation holes have been completed across the project, including a follow-up program of 37 holes totaling 2,024 meters. At Cruzeta, 28 reported holes established the first mineralized center. Five maiden holes at Boa Vista, roughly seven to eight kilometers south, established a second. Nine holes remain pending.

The Power Architecture Is Already Changing

NVIDIA Corporation (Nasdaq: NVDA) is pushing the 800 VDC transition into the AI ecosystem.

NVIDIA, Google and Microsoft published a joint 800 VDC white paper through the Open Compute Project in March, followed by an LVDC solid-state transformer specification in July. NVIDIA says more than 80 equipment manufacturers and infrastructure companies are already building products to the specification. An MGX-compatible 800 VDC power rack arrives in the second half of 2026, letting existing AC-powered facilities deliver 800 VDC to compute racks without rebuilding a building's electrical system.

Why change the architecture at all? At the power densities next-generation AI requires, efficiency losses that once looked small begin to compound. Higher-voltage DC distribution cuts the number of conversion stages between the grid and the accelerator.

Gallium Enters the Rack

Texas Instruments Incorporated (Nasdaq: TXN) shows where gallium fits.

In March, TI introduced a complete 800 VDC power architecture built with NVIDIA's reference design, reducing the path from the 800-volt bus to processor power to two conversion stages. The first includes an 800V-to-6V DC/DC bus converter using integrated gallium nitride power stages, with TI reporting 97.6% peak efficiency and power density above 2,000 watts per cubic inch.

That is a different demand story from electric vehicles, LEDs or solar cells. Gallium nitride is being designed directly into hardware intended for the next generation of AI infrastructure.

Supply is far more concentrated. Gallium is generally recovered as a by-product of bauxite and, to a lesser extent, zinc processing rather than from standalone gallium mines. The U.S. Geological Survey estimates China accounted for approximately 99% of worldwide primary low-purity gallium production in 2025.

Two Centers, the Same Vertical Pattern

That makes the geometry emerging at Arapaima worth following.

At Cruzeta, Spark's latest eleven-hole batch again encountered gallium from surface with broader rare earth mineralization beneath it. Hole ARA-RC-021 returned 32 meters from surface grading 73.9 g/t gallium oxide, including two meters at 91.4 g/t Ga₂O₃, and carried 32 meters at 1,947 ppm total rare earth oxides deeper in the profile.

Scandium has now joined the picture. Seven of the 28 Cruzeta holes returned scandium intervals from surface, led by 30 meters at 21.5 g/t scandium oxide. It is associated with the iron and titanium oxide fraction that also carries the gallium, rather than the clay fraction hosting the adsorbed rare earths.

Then came Boa Vista.

Five first-pass holes turned an undrilled geochemical target into a second mineralized center. Hole ARA-RC-007 produced a project-record gallium assay of 114.3 g/t Ga₂O₃ over two meters from surface. All five encountered gallium at surface with rare earth mineralization below, and everyone ended in rare earth mineralization above Spark's reporting basis.

Defense Was Already Buying

AI infrastructure is the emerging application. Defense electronics are the established one.

Raytheon, an RTX Corporation (NYSE: RTX) business, received a $1.8 billion U.S. Navy contract extension in July for its SPY-6 radar family, with options that could bring cumulative value to $3.3 billion. The radars are built in Andover, Massachusetts at a site with its own gallium nitride foundry, and an $800 million investment to modernize that manufacturing has the company expecting to double SPY-6 output by 2028.

The significance for gallium is not one customer or one application. It is established defense demand converging with an AI power architecture now being commercialized across a far larger ecosystem.

Nine Holes and One Bigger Question

Spark remains in the exploration and discovery stage, with the focus now shifting toward defining the scale, continuity and recoverability of the mineralization identified at Arapaima. While a mineral resource estimate and economic study have yet to be completed, the growing body of drill results is providing an increasingly detailed picture of the project's gallium, scandium and rare earth potential.

Metallurgical test work is already underway at ANSTO in Australia, with scandium now included alongside gallium and rare earths in the test program. At the same time, infill drilling at Cruzeta is being planned to support a potential maiden resource estimate, an important next step in moving the project from discovery toward a more defined development case.

Forty-two holes have now been drilled, two mineralized centers have emerged, and nine results remain pending. Spark has demonstrated that gallium occurs alongside rare earths and scandium at Arapaima, creating a compelling exploration story at a time when gallium is becoming increasingly relevant to both advanced defense electronics and the next generation of AI power infrastructure. The next results could help determine just how significant that opportunity may become.
