Lynas Builds a Heavy Rare Earth Beachhead — Outside China

In May 2025, Lynas Rare Earths became the first company outside China to

produce commercial quantities of separated dysprosium oxide. Combined

with a Malaysian NdPr capacity upgrade to 10,500 tonnes per year and a

new Texas refinery scheduled for commissioning, the Australian producer

has built the template for a non-Chinese heavy-rare-earth supply chain

at scale.¹

The Q1 2025 Breakthrough

Lynas Rare Earths' first-quarter 2025 results showed the company in full

growth mode. Total rare-earth-oxide production reached 1,911 tonnes,

with NdPr output at 1,509 tonnes — a 16.7 percent quarter-on-quarter

increase.¹ The pace signalled that the Malaysian separation facility

upgrade was delivering as promised, and that Lynas was on track for the

10,500-12,000-tonne-per-year NdPr target it set for full-year 2025.

The NdPr tonnage is commercially meaningful. At roughly one-fifth of

non-Chinese global NdPr supply, Lynas's 2025 production established the

company as the reference non-Chinese producer in the market. Every

offtake negotiation, every customer risk-management discussion, and

every policy briefing on rare-earth security referenced Lynas volumes as

a baseline.

Mt Weld and the Malaysian Plant

Lynas's footprint rests on two operations. The Mt Weld mine in Western

Australia hosts one of the world's highest-grade carbonatite-bearing

rare-earth deposits and supplies concentrate to Lynas's processing

chain. From Mt Weld the material is shipped to Malaysia, where Lynas

operates an extensive separation facility that turns the concentrate

into individual rare-earth oxides.

The 2025 Malaysian plant upgrade took NdPr oxide capacity from roughly

7,200 tonnes per year to 10,500 tonnes per year — a 46 percent increase

on the prior nameplate.¹ Capacity expansions in the separation segment

are difficult because they require either additional solvent-extraction

trains or more efficient use of existing ones, and both approaches

involve long lead times and careful commissioning work. Lynas executed

the upgrade while maintaining commercial output — no small feat.

The Malaysian facility's location is strategic. Malaysian regulation

permits processing of feedstock containing thorium and uranium, which

many Western jurisdictions handle less gracefully, and the country's

industrial base supports the heavy chemical and infrastructure demands

of a rare-earth separation plant. That combination is one of the reasons

Lynas has been able to build a competitive operation on non-Chinese

soil.

Malaysia has also provided regulatory stability. Despite periodic

political debates about the plant's thorium-bearing residues, Lynas's

operating licence has been consistently renewed, and the company has

made tangible investments in residue-management infrastructure that have

satisfied Malaysian regulators. Brazilian rare-earth producers

considering their own downstream processing can learn from this

regulatory trajectory as they plan for similar host-country

relationships.

The Seadrift Texas Expansion

Lynas's next expansion is in Seadrift, Texas. The facility is scheduled

for commissioning in 2025-2026 and is designed to produce an estimated

1,000-1,300 tonnes per year of light rare-earth NdPr oxide and

2,500-3,000 tonnes per year of heavy rare-earth oxides.¹ For a single

facility, those are substantial numbers.

The Seadrift plant is being built with U.S. Department of Defense

support, reflecting the same strategic logic that drove the MP Materials

10X partnership. Lynas offers the DoD a non-Chinese heavy-rare-earth

supply chain with an existing operational track record — something MP

Materials and other U.S. producers are still building. For Washington,

the attractiveness of supporting a non-Chinese, allied-country operation

to expand in the United States is self-evident.

Seadrift's 2,500-3,000-tonne heavy-rare-earth capacity is particularly

strategic. If delivered on schedule, it would represent the largest

non-Chinese heavy-rare-earth separation capability in existence,

complementing the Malaysian dysprosium milestone and giving Western

customers a diversified supply base within the Americas itself — not

simply dependent on cross-Pacific shipments from Malaysia.

Dysprosium Outside China — A Historic First

On 16 May 2025, Lynas announced the successful production of dysprosium

oxide at its Malaysian facility. The milestone is notable because it

made Lynas the first commercial producer of separated heavy rare earths

outside China — a distinction that carries both symbolic and practical

weight.¹

The symbolic dimension matters because heavy-rare-earth separation has

been treated for two decades as the single most difficult step to

replicate outside China. Light-rare-earth separation was industrialised

earlier (Lynas at Mt Weld, MP Materials at Mountain Pass), but heavy

rare earths require more sophisticated processing chemistry and carry a

particular reputation for operational difficulty. By producing

commercial dysprosium oxide, Lynas demonstrated that the difficulty is

surmountable.

The practical dimension is that a portion of the world's dysprosium and

terbium supply is now available from a source that cannot be disrupted

by Chinese export licensing. In a market where dysprosium traded at

roughly US$250 per kilogram and terbium above US$1,000 per kilogram

during 2025, that independence has commercial as well as strategic

value.²

What Lynas's Trajectory Shows Brazil

Lynas's path from mine to fully integrated light- and heavy-rare-earth

producer took roughly 15 years of sustained capital investment and

operational refinement. That timeline is instructive for Brazilian

producers. Serra Verde's current 2,000-tonne-per-year production and

2027 target of 6,500 tonnes compare favourably to Lynas's early-stage

output in the mid-2010s. Aclara's target of 2028 commercial production

and Meteoric's pre-feasibility work on Caldeira are likewise consistent

with the multi-year buildout that characterised Lynas's journey.

The lesson is that scale in rare earths is built patiently rather than

rapidly. Brazilian producers who execute through the 2025-2030 ramp will

be following a playbook that Lynas has already validated. The difference

is that Brazil is building in a demand environment that is structurally

tighter than the one Lynas faced — which should accelerate the revenue

curve even if the operational buildout takes a similar amount of time.

Outlook

Lynas's Q1 2025 results, Malaysian upgrade, Seadrift commissioning and

heavy-rare-earth breakthrough together establish the Australian producer

as the benchmark for non-Chinese rare-earth capability. For Brazil, that

benchmark is useful in two ways: as a proof of concept that a

non-Chinese operator can build an integrated, heavy-rare-earth-capable

supply chain, and as a partner or reference case for investors who look

for track records before committing capital to new jurisdictions.
