Ionic Mineral Technologies (Silicon Ridge)

A private Utah company that makes nano-silicon battery anode material and alumina from halloysite clay, and since December 2025 has presented its Silicon Ridge clay lease near Utah Lake as a deposit of rare earths and other critical minerals. It is not related to Ionic Rare Earths or its Belfast subsidiary.

Points to check

Facts from the sources on this page that a reader should weigh before relying on the company's own figures.

About three-quarters of the Silicon Ridge resource (247.0 Mt of about 330 Mt) is Inferred and is included in the PEA production schedule; the PEA is +/-35% accuracy and there is no Mineral Reserve (Business Wire, 15 Jul 2026).
No rare earth grade (TREO or individual Nd, Pr, Dy, Tb) has been published; the only public grade, about 2,700 ppm, combines rare earths with other critical metals and covers about 11% of the area to 100 ft depth (Business Wire, 11 Dec 2025).
Rare earths are a minority co-product in the PEA: alumina is about 51% of life-of-mine value, and the rare earth product form, annual output and any separation step are not described (Business Wire, 15 Jul 2026).
The full PEA technical report is not public; the company says qualified parties can request it under NDA (Business Wire, 15 Jul 2026).
No binding offtake, government award or customer for any Ionic MT product has been announced; the July 2025 Series B release names no customers or investors (Business Wire, 10 Jul 2025).

At a glance

Founded: 2020 — Founded in 2020 as a startup to make nano-silicon battery anode material from halloysite clay; emerged from stealth in 2022 with Ionisil. Since December 2025 it has also presented its Silicon Ridge halloysite lease in the Lake Mountains (Utah County) as a rare earth and critical mineral deposit. Founder and CEO is Andre Zeitoun.
Headquarters: Provo, Utah, USA
Ownership: Private. Closed a $29 million Series B in July 2025 (investors not named in the release). Citigroup is exclusive capital markets adviser; the CEO said in February 2026 the company is looking at a 2027 IPO after securing offtake agreements and scale-up funding.
Stage: Early stage. A preliminary economic assessment (July 2026) values rare earths as a co-product, but no rare earth grade, output or product has been published, and there is no investment decision.
Listing: Private.
Revenue: Not publicly disclosed. This company does not publish revenue and no named third party has published an estimate of it.

Narrative

Ionic Mineral Technologies, known as Ionic MT, was founded in Provo, Utah in 2020 to make a nano-silicon battery anode material, Ionisil, from halloysite, a tubular kaolin-group clay: acid removes the alumina and the remaining silica is reduced to silicon with magnesium. It raised $29 million in a Series B round in July 2025 to scale Ionisil toward 1,000 t/yr and a boehmite alumina product, IonAl, toward 5,000 t/yr at its Provo plant; no production volumes, revenue or customers have been published since. In November 2024 it leased about 4,000 acres of Utah state trust land in the Lake Mountains of Utah County, which it calls Silicon Ridge, and expanded the lease to about 13,000 acres in February 2026. In December 2025 it announced rare earths and other critical metals in the clay there, giving only a combined grade of about 2,700 ppm over about 11% of the area. A preliminary economic assessment under the US S-K 1300 rules, prepared by SGS and released in July 2026, reports a resource of about 330 Mt, three-quarters of it Inferred, and plans 2.0 Mt/yr of halloysite concentrate leached with hydrochloric acid to recover alumina, rubidium, cesium, gallium, germanium, nano-silica and 13 rare earth oxides; alumina is about half of the projected value. The public release gives no rare earth grade, annual rare earth output, product form or separation step, and the full report is available only under a nondisclosure agreement. The company has named no offtake, government award or investment decision; its chief executive has said it is considering a public listing in 2027, and in August 2026 it hired a chief technology officer who previously worked on the Mountain Pass rebuild.

Where public sources disagree

Processing route: the Dec 2025 discovery release and the Mar 2026 Michael Wright release describe low-temperature ion exchange that avoids roasting and heavy acids, while the Jul 2026 PEA release describes atmospheric hydrochloric acid leaching with industrial acid regeneration (about 97% reagent recapture). Sources: Business Wire 11 Dec 2025; Business Wire 4 Mar 2026; Business Wire 15 Jul 2026.
Drilling meters: the Dec 2025 release cites 106 boreholes totaling over 10,000 m plus 35 trenches; the Jul 2026 PEA release cites more than 100 holes totaling about 4.7 km (about 15,300 ft). Sources: Business Wire 11 Dec 2025 (via Eagle-Tribune repost); Business Wire 15 Jul 2026.
Land position: Feb 2026 release gives about 13,000 contiguous acres; Jul 2026 PEA release and Hoodline (Apr 2026) give a roughly 12,000-acre district. Grist (Dec 2025) reports an initial 4,053-acre lease in 2023, while the company's lease announcement is dated Nov 2024 (4,000 acres).
Provo capacity: electrive (Nov 2023) reported 2,000 t/yr initial nano-silicon capacity from H2 2024 rising to 5,000 t; The EV Report (May 2024) reported 7,000 t of annual capacity tied to Ionisil with completion in Sep 2024; the Jul 2025 Series B release gives targets of 1,000 t/yr Ionisil and 5,000 t/yr IonAl.

How this page is sourced

Everything here comes from public sources — company filings, annual reports, exchange announcements, government releases and trade press. Every figure is linked to the document it came from and carries the date that document was published, because a capacity number without a date is not a fact, it is a rumor with a decimal point.

What is deliberately absent: material nonpublic information. I have spent more than two decades in this industry and a good deal of what I know about these companies I learned under NDA. Those obligations do not expire and they do not bend for a website. Nothing I have been told in confidence appears here in any form, and nothing on this page — or missing from it — should be read as a signal about what I know privately. I hold NDAs absolutely. It is the reason clients tell me things.

Judgment is the other thing left out on purpose. This page reports what has been published and who published it. Whether a target is credible, whether a ramp will hold, whether a capacity figure survives contact with the plant behind it — that is the work I do for clients, and it does not belong in a free reference page.

Where public sources disagree, I say so rather than picking a winner. Where a figure has not been published, the field says so rather than carrying an estimate. An empty field is information too.

Public filings tell you what a company has said. Whether it holds up is a different question, and the one I get hired to answer.
