1. Why holmium is a strategic asset
Prime Minister Carney, holmium sits at the intersection of three transitions that will define Canada's industrial position for the next thirty years: the energy transition, the digital transition, and the geopolitical re-shoring of critical supply chains. It is one of the rarest of the heavy rare earths, yet it is physically irreplaceable in applications that no other element can serve as well.
What distinguishes holmium is the size of its magnetic moment — 10.6 Bohr magnetons, the highest of any naturally occurring element — and its sharp, narrow optical transitions. These are not incremental advantages. They are the reason holmium, and not a cheaper substitute, is used at the pole pieces of the strongest research magnets ever built, and in the surgical lasers that fragment kidney stones with millimetre precision.
- Energy transition: high-performance magnets, precision lasers, control materials for advanced reactors and small modular reactors (SMRs).
- Digital transition: candidate materials for artificial synapses, memristors and neuromorphic AI hardware — currently at the research hypothesis stage.
- Geopolitical transition: today's separated heavy rare earths come overwhelmingly from one country. Canada holds the deposits to offer an alternative.
No holmium-dominant mineral exists anywhere on Earth. Holmium is never mined for its own sake — it is recovered as a dilute passenger in heavy-rare-earth ores, at grades of a few tenths of a percent. Whoever controls separation capacity controls the element.
Through compounds such as Ho₂S₃, holmium could eventually support electronic components that do not yet exist commercially: artificial synapses, adaptive photonic sensors and spintronic devices. These prospects are addressed honestly below — including what has not yet been demonstrated in any laboratory.
2. Why now: a closing window of opportunity
Strategic minerals policy is a timing exercise. Holmium has been a scientific curiosity for a century; what has changed in the last three years is that five independent pressures have converged at once. Acting during that convergence costs a fraction of what acting after it would.
Separated heavy rare earths come overwhelmingly from a single jurisdiction, and export controls on rare-earth technologies have moved from theoretical risk to active policy instrument. Buyers are now paying a premium for provenance, not just for product.
Canada is among the first G7 countries to move a grid-scale small modular reactor into construction. Reactor programs need neutron-absorbing control materials qualified years before first criticality — which means the sourcing decision happens now, not at commissioning.
Ho:YAG is the clinical standard for kidney-stone lithotripsy and prostate enucleation. An ageing population and rising stone incidence expand a market whose crystal supply is concentrated in two countries. Canadian hospitals are buyers with no domestic supplier.
The industry is actively screening exotic compounds for analog and in-memory computing. Ho₂S₃ is unmeasured — which is precisely the opportunity: the cost of being first to publish its device properties is low today and rises as others begin looking.
The nearest magnetic alternative, dysprosium, is itself supply-constrained and already spoken for by the permanent-magnet sector. Where holmium's specific properties are required, substitution means accepting worse performance, not equal performance cheaper.
Canada already holds the deposits and, in Saskatoon, the separation plant. The missing pieces are measurements and a procurement signal — the two cheapest components of the entire chain. Rarely is the binding constraint this inexpensive to remove.
Qualitative illustration of first-mover economics in an unmeasured material. The shape, not the values, is the argument.
The counter-argument, stated fairly
A window of opportunity is not proof of a payoff. If Ho₂S₃ measurements return null results, the digital-transition argument collapses and only the proven applications — lasers, magnets, nuclear control, metrology — remain. Those alone justify a modest program; the rest is upside.
3. Global demand and the holmium market
The world consumes only a handful of tonnes of holmium per year — and that is precisely what makes it interesting. Holmium is not a bulk commodity; it is a value multiplier whose price is set by what it enables, not by its tonnage.
Today's holmium demand is modest in volume but concentrated in very high-value uses:
- Medical and industrial lasers (Ho:YAG at 2.1 μm, the clinical standard for urology).
- Specialty magnets for nuclear and scientific applications.
- Dopants for optical fibres, spectrophotometer calibration standards and quantum materials.
Trade estimates put annual metal production near 10 tonnes per year (Minor Metals Trade Association), while the USGS quotes separated Ho₂O₃ at roughly US$70/kg for 2025. These figures describe different chemical forms and years; they must never be mixed into a single "price".
With the emergence of:
- neuromorphic (brain-inspired) hardware,
- memristive components,
- advanced medical imaging and targeted radiotherapy,
- small modular nuclear reactors,
holmium-containing components could address markets worth billions, even if the metal tonnage stays small. The strategic play is not mining volume — it is capturing the margin chain from separated oxide to finished device.
Holmium's position in the rare-earth market
| Segment | Role of holmium | Market status | How Canada can position itself |
|---|---|---|---|
| Lasers & medicine | Key dopant for Ho:YAG surgical lasers; Ho-166 radioembolization | Existing market, very high margins | High-purity Ho oxide and crystal growth |
| Neuromorphic electronics | Candidate material for artificial synapses (Ho₂S₃) | Hypothesis stage — no published device | Fund measurement research first; do not pre-sell products |
| Energy & smart grids | Magnet pole pieces, precision sensors, control rods | Existing niche demand | Partnerships with utilities and instrument makers |
| Spintronics & quantum | Extreme magnetic moment; single-atom bit (IBM, 2017) | Emerging, highly strategic | University R&D plus patient capital |
4. Canadian resources and the geopolitical advantage
Canada already holds holmium resources inside its heavy-rare-earth (HREE) deposits. Holmium is never mined directly: it occurs as a dilute co-product in rare-earth ores. Below is the complete provincial inventory — including the provinces where holmium is not present, because honesty about absence matters as much as claims of abundance.
- Quebec: Montviel, Ashram, Strange Lake, Kipawa — the most holmium-relevant deposits in Canada.
- Northwest Territories: Nechalacho (Thor Lake), about 100 km east-southeast of Yellowknife — the only Canadian site to have produced heavy rare earths, at pilot scale (2021–2022).
- British Columbia: Wicheeda and other carbonatites — a low holmium fraction, but strong mining infrastructure.
- Saskatchewan: Hoidas Lake, near Uranium City — apatite–allanite veins with some heavy-rare-earth content; the province also hosts the SRC separation facility in Saskatoon.
- Newfoundland and Labrador: the Strange Lake deposit straddles the Quebec–Labrador border; further anomalies exist along the Nunavik corridor.
- Ontario: no active rare-earth deposit; possible holmium in historical carbonatites (e.g. Clay-Howells, Blind River) — not exploited.
- Manitoba: no documented significant holmium deposit; possible presence in pegmatites, unconfirmed.
- Alberta: no known rare-earth deposit; holmium absent from the provincial database.
- New Brunswick: no active deposit; possible holmium in peralkaline granites (e.g. Mount Pleasant) — unconfirmed.
- Nova Scotia: no documented deposit; theoretical presence in pegmatites, unconfirmed.
- Prince Edward Island: no rare-earth mineral resource identified.
- Yukon: no documented holmium deposit; possible presence in heavy-rare-earth prospects under exploration — unconfirmed.
- Nunavut: no documented holmium deposit; exploration underway in Canadian Shield regions — unconfirmed.
Today, holmium is not produced at all in Canada, but the deposits exist. A structured investment program would make it possible to:
- secure a non-Chinese heavy-rare-earth supply chain,
- build a complete value chain: mining → separation → advanced materials (Ho₂S₃) → electronic components,
- position Canada as a strategic supplier for medical, nuclear and next-generation electronic technologies.
Provincial summary of holmium potential in Canada
| Province / Territory | Main deposit | Type | Holmium potential | Status |
|---|---|---|---|---|
| Quebec | Strange Lake, Kipawa, Ashram, Montviel | Peralkaline / Carbonatite | High (HREE-rich) | Pre-construction / development |
| Northwest Territories | Nechalacho (Thor Lake) | Peralkaline | High (HREE > 20 % TREO) | Past pilot production, restructuring |
| Saskatchewan | Hoidas Lake | Apatite–allanite veins | Moderate | Exploration |
| British Columbia | Wicheeda | Carbonatite | Low | Development |
| Newfoundland and Labrador | Strange Lake (extension) | Peralkaline | High (shared with Quebec) | Pre-construction |
| Ontario | Clay‑Howells, Blind River (historical) | Carbonatite / Granite | Low | Not exploited |
| Manitoba | Pegmatites (unconfirmed) | Pegmatite | Unconfirmed | General exploration |
| Alberta | None | — | Confirmed absence | — |
| New Brunswick | Mount Pleasant (unconfirmed) | Peralkaline granite | Unconfirmed | General exploration |
| Nova Scotia | Pegmatites (unconfirmed) | Pegmatite | Unconfirmed | General exploration |
| Prince Edward Island | None | — | Confirmed absence | — |
| Yukon | Under exploration | Peralkaline (unconfirmed) | Unconfirmed | General exploration |
| Nunavut | Under exploration | Peralkaline (unconfirmed) | Unconfirmed | General exploration |
A note of caution
The presence of holmium in a rock does not mean it will be extracted. Commercial production depends on the grade, the separation process, the infrastructure and a paying customer. No Canadian project separates holmium individually today. Canada does not produce holmium — it holds deposits from which it could one day produce it.
5. Ho₂S₃: from ore to a high-margin component
Holmium reaches its full value only once it is transformed into functional materials. Ho₂S₃ (holmium(III) sulfide) is the derivative this letter focuses on: a documented, crystallographically characterized compound whose device properties are — critically — not yet measured.
What the published record actually supports
- Orange-yellow crystals, monoclinic structure (space group P2₁/m, No. 11), density 5.92 g/cm³.
- Synthesized from Ho₂O₃ and H₂S at 1325 °C, or directly from the elements; purifiable by iodine vapour transport.
- Cubic and orthorhombic polymorphs under high pressure — relevant to pressure-sensing research.
- The Ho³⁺ ion carries the ground term ⁵I₈, the source of holmium's exceptional magnetism.
What the record does not support: resistive switching, a measured bandgap, ionic mobility numbers, or any working Ho₂S₃ device. Those properties are hypotheses that a serious program would test first — cheaply, quickly and with clear stop criteria.
Why the testing-first sequence matters commercially
The measurement program costs a small laboratory budget; a fabrication plant costs orders of magnitude more. Financing the measurements first converts speculation into priced risk, and it does so before any public claim is made. That sequencing is the difference between building an industry and selling a story.
Illustrative value multiplication along the Ho₂S₃ chain
Values escalate as holmium moves from commodity oxide toward finished function. The last bar is conditional on measurements that do not yet exist.
| Stage | Indicative cost basis | What is being sold | Caveat |
|---|---|---|---|
| Ho₂O₃ feedstock (99.5 %) | ≈ US$70/kg (USGS 2025) | Separated rare-earth oxide | Verified benchmark price |
| Phase-pure Ho₂S₃ powder | Feedstock + 1325 °C sulfidation | Research-grade material | No commercial supplier identified |
| Thin-film Ho₂S₃ test device | Deposition, electrodes, packaging | First experimental data | No published device exists today |
| Qualified electronic component | Years of reliability testing | High-margin integrated function | Conditional on proof of switching |
Deliberately conservative: no unit-sale prices for hypothetical synapses or transistors are asserted here, because no Ho₂S₃ device has been demonstrated. Figures from the earlier version of this letter that implied otherwise have been replaced with the honest chain above.
6. The Ho₂S₃ measurement program: cost, timeline, stop criteria
Everything speculative in this letter reduces to a single question that can be answered in two years for the price of a mid-sized research grant. Below is that program, costed and bounded — including the conditions under which it should be stopped.
CAD 1–3 million total, spread across three work packages. This is a rounding error against critical-minerals program budgets, and it is the entire cost of removing the central uncertainty.
18–24 months. Synthesis and characterization run in parallel from month 4; device fabrication begins only once phase-pure material is confirmed.
University and national-laboratory facilities that already exist. No new building, no capital plant, no long-lead equipment procurement.
Work packages and deliverables
| Work package | Months | Indicative share | Deliverable | Method |
|---|---|---|---|---|
| WP1 — Phase-pure synthesis | 1–9 | ~25 % | Reproducible Ho₂S₃ powder and thin films with verified stoichiometry | Sulfidation of Ho₂O₃; XRD, EDS/WDS, XPS |
| WP2 — Fundamental properties | 6–18 | ~40 % | Bandgap, carrier type and density, temperature-dependent conductivity, magnetic susceptibility | UV-Vis diffuse reflectance, ellipsometry, Hall effect, SQUID |
| WP3 — Device screening | 12–24 | ~25 % | Switching yes/no, with area scaling and electrode controls | Metal–insulator–metal cells; I–V, pulse, endurance, retention |
| WP4 — Stability | 9–24 | ~10 % | Air, humidity and thermal stability of nanometre films | Accelerated ageing under controlled atmosphere |
Stop criteria — agreed before the first dollar is spent
- Gate 1 (month 9): if phase-pure, reproducible films cannot be made, stop. Everything downstream is meaningless without them.
- Gate 2 (month 18): if the bandgap and transport data place Ho₂S₃ outside any useful semiconductor window, stop and publish. The measurement itself is the contribution.
- Gate 3 (month 24): if apparent switching cannot be distinguished from dielectric breakdown, contact effects or thermal artefacts under area scaling and electrode controls, declare a null result and close the file.
- No gate extension without new evidence. Programs die from optimistic extensions, not from honest null results.
Why a null result is still a good outcome
Ho₂S₃'s device properties are absent from the literature. Measuring them produces a citable reference regardless of sign — and a documented null result prevents other jurisdictions from spending far more to learn the same thing. Either way, Canada owns the answer. Very few research investments have a floor this solid.
7. Return on investment — a phased strategy
Investing in holmium and Ho₂S₃ is not a mining play. It is the creation of a complete technological value chain, and the phasing below is designed so that no phase is funded before the previous one has produced evidence.
- Support pre-construction at HREE projects (Strange Lake, Kipawa, Nechalacho).
- Extend existing separation capacity (SRC Saskatoon) toward Dy–Ho–Er splits.
- Objective: secure access to separated Ho₂O₃.
ROI: moderate but strategic — supply security is the asset.
- Fund synthesis and fundamental measurements (bandgap, transport, switching).
- Build thin-film capability with universities and national labs.
- Objective: Canadian-owned materials IP.
ROI: high if measurements succeed; bounded loss if they fail.
- Only after Phase 2 evidence: device prototyping and qualification.
- Integration with medical, nuclear, sensing and AI-hardware customers.
ROI: highest — but conditional. This phase must never be pre-sold.
What the return actually looks like
- Financial: margins concentrate at the separation and component stages, not at the mine gate.
- Strategic: a non-Chinese source of a heavy rare earth is itself worth a premium in procurement policy.
- Scientific: even a null result on Ho₂S₃ switching generates publishable, citable measurement data the field currently lacks.
- Reputational: Canada becomes the jurisdiction that funded the honest measurement — the opposite of a pump-and-promote scheme.
8. Investing in the future: the technological advantages
Holmium is valuable not merely for its scarcity, but for physical properties no other element reproduces at this level. Investing in its value chain means buying a position in technologies whose demand grows faster than supply.
- Magnetic moment of 10.6 μB — the highest of any naturally occurring element.
- Highest magnetic permeability and saturation — indispensable for pole pieces in the strongest research magnets.
- Applications: high-resolution MRI, spectroscopy, high-field physics research.
- Laser emission at 2.1 μm (Ho:YAG): eye-safe window, strong water absorption.
- Precision surgery (lithotripsy, prostate enucleation), rangefinding, LIDAR.
- Optical calibration standard: Ho₂O₃ glasses and solutions used by national metrology labs.
- Efficient neutron absorber: control rods and burnable poison in research reactors.
- Isotope Ho-166: targeted radioembolization of liver cancers.
- 166m¹Ho: multi-gamma calibration standard for spectrometers.
- NIR-II sensitizer for deep-tissue bio-imaging (1143 nm excitation).
- One data bit stored on a single holmium atom (IBM demonstration, 2017).
- Candidate for qubits and quantum memory via hyperfine interaction.
Why holmium outperforms the alternatives
Approximate effective moments, order-of-magnitude comparison only. Holmium's record applies to the metal — it does not automatically transfer to compounds such as Ho₂S₃.
Comparison table
| Advantage | Holmium | Closest alternative | Gap |
|---|---|---|---|
| Magnetic moment | 10.6 μB | Dysprosium (10.0 μB) | +6 %, absolute record |
| Field at magnet pole pieces | Highest known saturation | Iron, cobalt | Used in record-setting research magnets |
| Surgical laser at 2.1 μm | Ho:YAG (clinical standard) | Tm:YAG (2.01 μm), Er:YAG (2.94 μm) | Best tissue absorption/penetration trade-off |
| Neutron absorption | High, stable cross-section | Boron, cadmium, gadolinium | Better radiation resistance than cadmium |
9. Inventions to produce in Canada: from proven to prospective
Some of these inventions already exist and would simply be manufactured in Canada. Others are research concepts that first require fundamental measurements on Ho₂S₃. They are distinguished honestly below.
A. Products immediately industrializable in Canada
- Holmium pole pieces for the world's strongest research magnets — an existing scientific and medical market with very high margins.
- Ho:YAG crystals for surgical lasers — the global clinical standard, with current suppliers concentrated in the United States and China.
- Ho₂O₃ optical standards (glasses and solutions) for spectrophotometer calibration — used by NIST and its international counterparts.
- Holmium nuclear control rods for research reactors and small modular reactors (SMRs).
- NIR-II dopant for deep-tissue bio-imaging — an emerging market in oncology and preclinical imaging.
B. Prospective inventions — to be developed (undemonstrated hypotheses)
These concepts are motivated by holmium's properties, but none is yet a product. Each first requires fundamental Ho₂S₃ measurements that have never been published:
- Ho₂S₃ artificial synapses: a memristive thin film for low-power neuromorphic AI. Prerequisite: demonstrate reproducible resistive switching — never measured to date.
- Smart solar transistors: self-adaptive photoelectric sensors based on Ho₂S₃. Prerequisite: measure the bandgap and phototransport — no published data.
- Magneto-electric memories: a cell combining resistive state and local magnetic field. Prerequisite: Ho₂S₃ magnetoresistance — unmeasured.
- Cryogenic magnetic sensors: contactless thermometers exploiting Ho³⁺ susceptibility at low temperature.
- Spectral authentication tags: hard-to-forge optical signatures patterned into Ho₂S₃ films.
- Dual-mode radiation dosimeters: simultaneous optical and electrical dose readout for space and medical uses.
Maturity and potential by invention
| Invention | Maturity (TRL) | Target market | Main barrier |
|---|---|---|---|
| Holmium pole pieces | TRL 9 — existing product | Research, MRI, accelerators | Access to pure Ho metal |
| Ho:YAG crystals | TRL 9 — clinical standard | Surgery, dentistry, defence | Quality crystal growth |
| Ho₂O₃ standards | TRL 9 — metrology use | Laboratories, instruments | Purity and traceability |
| Nuclear control rods | TRL 7–8 — deployed | Research reactors, SMRs | Nuclear certification |
| Ho₂S₃ synapses | TRL 1 — hypothesis | AI hardware (massive potential) | No published switching measurement |
| Ho₂S₃ solar transistors | TRL 1 — hypothesis | Smart photovoltaics | Unknown bandgap |
A point of technical honesty
Category A rests on measured, commercialized holmium properties. Category B rests on untested hypotheses about Ho₂S₃. A credible investment strategy funds the fundamental measurements (bandgap, transport, switching) before any product promise. That sequencing is what separates a serious industry from speculation.
10. What this means for Canadians
Technical strategies only succeed when the public understands what is at stake. Below is the plain-language case — no chemistry degree required.
- High-skill positions in mining, chemical processing, crystal growth and metrology — in Quebec, Saskatchewan and the North, not only in large cities.
- Anchoring separation capacity at SRC Saskatoon keeps the highest-margin step on Canadian soil.
- Every phase creates exportable expertise, not just exported ore.
- Ho:YAG surgical lasers already fragment kidney stones and treat prostate disease in Canadian hospitals.
- Ho-166 radioembolization targets liver tumours while sparing healthy tissue.
- A domestic supply makes these tools independent of foreign export decisions.
- Holmium control materials matter for the small modular reactors Canada is planning.
- Stronger, more compact magnets support grid and motor efficiency.
- Resource security is energy security.
- Next-generation AI hardware will need exotic materials — whoever owns them writes the rules.
- Canada already demonstrated global relevance in quantum research; holmium extends that position.
- Owning the material pipeline means owning the standards conversation.
Qualitative positioning: each step to the right multiplies value per unit of holmium and keeps skilled employment domestic.
Common questions, straight answers
- "Is this another mining boom promise?" No. The tonnage is tiny by design; the strategy targets margin and sovereignty, not volume.
- "Will it raise my electricity bill?" No grid spending is involved; the reactor-relevant material is a small specialty input.
- "What about the environment?" Rare-earth processing requires acid cracking and solvent extraction; a credible Canadian program is conditional on modern waste handling and published environmental assessments.
- "Is the AI-hardware part real?" Not yet. Those applications are labelled TRL 1 hypotheses throughout this letter, and they only proceed if measurements succeed.
11. Illustrative production estimates — and the state of government engagement
Full disclosure first
No agreement, negotiation or memorandum exists between this initiative and the Prime Minister's Office or any mining company. This letter is a policy proposal, not the reporting of a deal. The figures below are illustrative arithmetic from public disclosures, not forecasts, reserves or commitments by anyone.
Illustrative holmium arithmetic by project
Companies report total rare-earth oxides (TREO), not holmium. To estimate the holmium content of a deposit, one applies a typical Ho₂O₃ share of the heavy-rare-earth basket (on the order of 1–2 % of TREO in peralkaline deposits, well under 1 % in carbonatites). These are screening numbers only — no project has published an audited holmium grade.
Order-of-magnitude screening estimates derived from public TREO figures and typical Ho₂O₃ fractions. Not resource statements. In-place tonnage is not recoverable tonnage.
Reading these numbers honestly
- Context: global holmium metal output is roughly 10 t/year. Even the smallest bar above represents centuries of current world demand — the constraint has never been the ore in the ground.
- The real bottleneck: building the separation stages (Dy–Ho–Er splits) costs tens of millions of dollars and only happens with a committed buyer.
- Recovery losses: mining recovery, cracking yield and separation yield compound; a realistic recoverable figure is a fraction of any in-place estimate.
- Timing: the most advanced projects (Strange Lake, Nechalacho) are years from commercial production even under favourable financing.
What a realistic government engagement would contain
Were this proposal presented to the Government of Canada, a credible ask would be modest and sequenced — not a mega-project announcement:
- Ask 1 — Measurements (~low millions $): fund a 24-month program to measure Ho₂S₃ bandgap, transport and switching at national labs and universities. Bounded cost, decisive output.
- Ask 2 — Assay transparency (no cost): request that projects receiving federal critical-minerals support publish per-element heavy-rare-earth assays including holmium, instead of TREO aggregates.
- Ask 3 — Separation option (conditional): commission a feasibility study on adding Dy–Ho–Er stages to an existing Canadian separation line, executed only if Ask 1 produces positive measurements.
- Ask 4 — Procurement signal (conditional): have federal research reactors and metrology institutes state willingness to qualify Canadian-separated Ho₂O₃, creating the committed buyer that unlocks private investment.
Why this sequencing protects the taxpayer
Each step costs more than the previous one and is gated by evidence. If Ho₂S₃ measurements fail, the program stops after the cheapest phase with publishable science and zero stranded industrial assets. If they succeed, each subsequent investment is made with knowledge no competitor currently has.
12. Province-by-province strategy: matching ideas to real resources
A national holmium strategy should not treat every province the same way. Each region has a different resource base, industrial fabric and realistic role. Some provinces are mining plays; others are processing, research or demand plays. Pretending otherwise wastes capital.
- Resources: Strange Lake, Kipawa, Ashram, Montviel — the densest cluster of holmium-relevant deposits in Canada.
- Situation: existing hydrometallurgy expertise (Géoméga's separation R&D), deep mining workforce, hydroelectric power.
- Strategy: host the pilot Ho₂S₃ measurement lab and the first separation stage dedicated to Dy–Ho–Er. Quebec is where the science and the ore meet.
- Resources: Nechalacho, the only site with past HREE production at pilot scale.
- Situation: project in restructuring; high logistics cost; strong Indigenous partnership framework already built.
- Strategy: not first production, but long-term feedstock security. Position Nechalacho as the strategic reserve that activates when demand is proven.
- Resources: Hoidas Lake deposit plus — critically — the SRC Rare Earth Processing Facility in Saskatoon, North America's first commercial-scale separation plant.
- Situation: midstream capacity already exists; no dependence on building a new plant from zero.
- Strategy: make SRC the national separation hub. A feasibility study on adding holmium-capable stages is cheap precisely because the facility already exists.
- Resources: Wicheeda carbonatite (low holmium fraction).
- Situation: Pacific ports (Vancouver, Prince Rupert), established mining services sector, proximity to Asian markets.
- Strategy: not a holmium play per se — but the export and refining-services corridor. BC's role is moving materials, not producing Ho.
- Resources: historical carbonatites, none active.
- Situation: Canada's manufacturing, medical-device and nuclear-engineering core; home to the buyers, not the mines.
- Strategy: anchor the procurement signal. Ontario hospitals, nuclear firms and instrument makers are the customers whose stated demand unlocks private mining investment elsewhere.
- Resources: no rare-earth deposits.
- Situation: world-class process-engineering workforce from oil and gas; solvent-extraction expertise directly transferable to rare-earth separation.
- Strategy: contribute engineering and process-design capability, not ore. Alberta's petrochemical sector is the closest existing analogue to SX plant operation.
- Resources: New Brunswick's Mount Pleasant is a tin-tungsten prospect with unconfirmed rare-earth traces; Nova Scotia, PEI: none documented. Newfoundland and Labrador shares Strange Lake with Quebec.
- Situation: no meaningful holmium geology outside the Labrador extension.
- Strategy: Labrador participates through Strange Lake; the other Atlantic provinces should not be sold a holmium story. Their critical-minerals opportunities lie elsewhere (e.g. copper, manganese).
- Resources: Canadian Shield exploration frontier, nothing confirmed for holmium.
- Situation: sparse infrastructure, high cost, long permitting timelines.
- Strategy: geological survey mapping only. No project-level spending until assay data confirms HREE enrichment.
Qualitative: bar length represents centrality to the strategy, not investment size. The watchlist provinces are included honestly, not sold a story.
The principle
A credible national strategy assigns each province the role its geology and industry actually support. Quebec mines and measures, Saskatchewan separates, the Northwest Territories bank the reserve, Ontario buys, Alberta engineers, British Columbia ships. Provinces without holmium geology are told so — that honesty is what makes the whole plan believable.
13. Why Quebec is the natural home for Ho₂S₃
Section 12 assigns Quebec the combined ore-and-science role. That assignment is not provincial favouritism — it follows from four assets that no other province holds simultaneously.
- Rare-earth separation is energy-intensive: hundreds of solvent-extraction stages running continuously.
- Hydro-Québec supplies that load at low carbon intensity and at industrial rates.
- This is a commercial asset, not just an environmental one: low-carbon separated oxide is a differentiated product for buyers with supply-chain emissions targets.
- Polytechnique Montréal — thin-film deposition and device characterization.
- INRS Énergie Matériaux Télécommunications (Varennes) — materials and photonics.
- Université de Sherbrooke — nanofabrication infrastructure suited to MIM test cells.
- McGill — condensed-matter and magnetic characterization.
- WP1 to WP3 of the measurement program could run without building anything new.
- Géoméga has developed rare-earth separation and recycling technology in Saint-Bruno.
- Quebec's aluminium sector carries deep electrometallurgy and molten-salt experience.
- The province therefore has both the chemistry and the operating culture that solvent-extraction plants demand.
- Strange Lake, Kipawa, Ashram and Montviel are all within or on Quebec's border.
- Single-jurisdiction permitting shortens timelines and simplifies Indigenous consultation frameworks.
- Ore, energy, chemistry and laboratories inside one regulatory perimeter is a genuinely rare combination.
Industrial synergies already present
Quebec's existing hydrogen, electrochemistry and battery-materials initiatives share the same underlying capabilities a holmium program needs: high-purity chemical handling, gas safety systems, electrochemical process control and clean-power integration. A holmium–Ho₂S₃ program would draw on that established base rather than create a parallel one — which is what makes the marginal cost low.
What Quebec still lacks
Honesty requires naming the gap: Quebec has no operating rare-earth separation plant. That capability currently exists in Saskatchewan. The realistic model is therefore collaborative — Quebec supplies ore, clean energy and laboratory science; Saskatchewan separates. Insisting that one province do everything would delay the program by years for no technical gain.
14. A direct message to Mark Carney
Holmium is not just another metal. It is a discreet but essential pivot of the next technology generation: medical lasers, nuclear control materials, quantum research and — if the measurements succeed — neuromorphic electronics.
Canada, and Quebec in particular, already holds the deposits, the expertise and the infrastructure to become the world reference for the holmium–Ho₂S₃–advanced-components value chain.
A structured investment in this value chain would deliver:
- a strong financial return through high-margin components,
- a strategic return by securing a critical resource outside the Chinese sphere,
- a societal return by placing Canada at the heart of tomorrow's technologies.
Investing in holmium today means investing in the physical infrastructure of tomorrow's intelligence — measured honestly, and funded in the right order.
