Points to check
Facts from the sources on this page that a reader should weigh before relying on the company's own figures.
- The company is private and publishes no financial statements; the last public cash figure is from 30 Jun 2015.
- The 2025 updated-PFS economics come from a company press-release summary; no full technical report was found publicly, and the release does not state the price deck.
- The Phase 1 capex of US$628M excludes contingency.
- The first-production target moved from 2028 (Jan 2024) to 2030 (Feb 2026), and there is no construction financing or investment decision yet; DFS completion is scheduled for H1 2027.
- The Mineral Reserve total (41.12 Mt @ 1.92% TREO) is unchanged from the 2014 estimate published with the 2015 PFS.
At a glance
- Founded
- Not established in public sources — Founding year not found in a public source. Frontier was listed on the Toronto Stock Exchange (TSX: FRO) from 2010 to 2015; shareholders approved delisting at a special meeting on 16 Sep 2015, citing depressed rare-earth prices and that talks with sovereign/strategic investors would go better as an unlisted company. It describes itself in 2026 as a privately held, Luxembourg-based company.
- Headquarters
- Luxembourg, Luxembourg
- Ownership
- Private (unlisted since 2015; formerly TSX: FRO). REIA (Jan 2024) describes it as controlled by management and related parties based in the EU. At the 2015 delisting vote, Chairman Philip Kenny, CEO James Kenny and associated nominee/management entities held about 52.3% of shares. Project-level interests: Korea Resources Corp (now Korea Mine Rehabilitation and Mineral Resources Corp, KOMIR) holds a 10% participating interest in Zandkopsdrift, acquired Dec 2012; South African BEE shareholders hold a 26% direct interest in the project. South Africa's Industrial Development Corporation (IDC) subscribed US$20M equity into the South African subsidiary Frontier Critical Minerals (stake percentage not disclosed).
- Stage
- Early stage. No investment decision: the DFS started in 2026 and is due H1 2027, with first production targeted for 2030. The only committed funding is a US$20M IDC equity subscription for the DFS.
- Listing
- Private.
- Revenue
- Not publicly disclosed. This company does not publish revenue and no named third party has published an estimate of it.
Capacity
Each date below links to the document the figure came from. A capacity figure with no source is not on this page.

| Zandkopsdrift 2015 PFS plan (superseded), including a separation plant at Saldanha | Out: 8,000 t/yr separated TREO Phase 1 (years 1-4), 16,000 t/yr Phase 2 (year 5+), 14 separated oxide products at 99%-99.999% from a 12-line SX plant at Saldanha | Historical | May 2015 |
Narrative
Zandkopsdrift is a weathered carbonatite in South Africa's Northern Cape, held under a mining right with its environmental authorization. Frontier Rare Earths, listed on the Toronto Stock Exchange from 2010 until shareholders approved delisting in 2015, published a pre-feasibility study in 2015 that sent concentrate to a separation plant at Saldanha; the current plan, updated from 2022 to 2025, separates NdPr oxide on site, about 3,038 t/yr, alongside 114 t/yr of dysprosium oxide, 25 t/yr of terbium oxide and manganese sulfate, for phase 1 capital of US$628 million before contingency. The reserve of 41.12 Mt at 1.92% TREO dates from 2014. In February 2026 the company announced a US$20 million equity investment by South Africa's Industrial Development Corporation, with an option on up to 10% of production, and agreements with Carester to supply solvent-extraction technology and to buy the mixed heavy rare earth carbonate for seven years for separation at Lacq, France. A definitive feasibility study by Dorfner Anzaplan is due in the first half of 2027, and first production is targeted for 2030, two years later than stated in January 2024. Korea Mine Rehabilitation and Mineral Resources Corporation has held 10% of the project since 2012.
Where public sources disagree
- Two sources disagree on the updated-PFS IRR: the company release (5 Feb 2026) gives post-tax IRR of 28% ungeared and 34% at 50% gearing; Mining Weekly (5 Feb 2026) and Polity/Mining Weekly Junior Indaba coverage (Jun 2026) give 34% ungeared and 50% geared.
- Two sources disagree on annual magnet rare-earth output: Climate Home News (6 Mar 2026) and the REIA release (24 Jan 2024) give 4,000 t/yr of magnet rare earths; the company release (5 Feb 2026) gives 3,038 t/yr NdPr oxide + 114 t/yr Dy oxide + 25 t/yr Tb oxide = 3,177 t/yr, about 823 t/yr less.
- Two sources describe the separation location differently: Climate Home News (6 Mar 2026) says Carester 'will separate and process the mine's rare earths' at a facility in France; the company release (5 Feb 2026) says NdPr oxide is produced on site at Zandkopsdrift with Carester technology and only the MHREC goes to Carester's Lacq facility.
- The first-production target differs by source date: REIA release (24 Jan 2024) says 2028; company release (5 Feb 2026) says 2030.

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.
