U.S. Tungsten Strategy Links Mining, Conversion,
Manufacturing and Procurement
The United States committed US$450 million to a tungsten platform
spanning mining, ammonium paratungstate conversion and component
manufacturing. During the same week, Hemerdon began processing ore,
Rwanda entered a state backed tungsten venture and Los Santos secured
a long term offtake route for tailings retreatment. Canada assembled
investment and project pipelines, Europe proposed a common raw
materials buyer and several mines and plants crossed operating thresholds.

What this week says
Six readings from the evidence
01
Tungsten supply is being assembled through several institutions
Public equity, mine restart, state ownership, tailings retreatment,
customer offtake and government procurement appeared around the
same mineral during one week.
02
Canada is building an investment and partnership pipeline
The Summit created visibility for 63 mining and metals opportunities.
Marathon assembled project finance, Ontario outlined processing support
and Canada proposed deeper cooperation with Europe and Norway.
03
Startup, ramp up and commercial production are distinct stages
Mesabi entered startup, Hemerdon began processing ore and Hammerdown
crossed a declared commercial production threshold after a defined
operating test.
04
Processing and qualification remain the connection to customers
Zanaga moved into bulk metallurgical validation, IperionX tested
continuous titanium processing and Malmbjerg completed fieldwork
for engineering and future pilot work.
05
Buyers and regulators are shaping who may control mineral assets
Europe proposed a common raw materials buyer, issued objections to
a nickel acquisition and Greenland announced a security agreement
whose investment provisions remain unpublished.
06
Public authority and accountability remained part of execution
Federal assessment began at Berg Copper, a Saskatchewan screening
decision remained limited to one potash module and Nigeria opened
an inquiry into deaths in custody after mining arrests.
Weekly reading:
this week made the distance between public strategy and dependable
supply easier to measure. Capital and contracts moved closer to mines,
plants and customers, while operating performance, legal control and
public legitimacy remained separate conditions.
01
Tungsten supply
Four jurisdictions advanced different parts of the same supply problem
No single announcement created a complete tungsten chain. Together,
the developments reached capital, mining, processing, customer demand
and government procurement.
United States · ElmetUS$450M
Public equity and procurement
The investment is intended to expand domestic manufacturing,
restart APT conversion and coordinate allied sourcing.(APT:hydrometallurgical refining process that transforms raw tungsten ore concentrate into Ammonium Paratungstate)
United Kingdom · HemerdonOre processing
Mine restart enters production
The plant is processing tungsten and tin ore while throughput,
recovery, quality and costs remain to be demonstrated at steady state.
Rwanda · Almonty25% state equity
Existing material and processing rights
The platform combines state ownership, a concession, a mobile
processing licence and potential collection from licensed producers.
Spain / Austria · Los SantosTake or pay
Tailings linked to an integrated smelter
A minimum 1,720 tonnes of contained WO3 (tungsten trioxide) secured a route to market
before the Los Santos processing plant restarts.
The Los Santos agreement includes index linked pricing with a floor
and a conditional US$3 million payment. It creates a commercial route,
but production, plant reactivation and first delivery remain ahead.
Reading
Tungsten supply is being built through the combination of capital,
operating assets, processing rights, customer contracts and public demand.
What follows
Elmet closing and drawdowns, Hemerdon operating data, implementation
in Rwanda, Los Santos reactivation and the first contracted deliveries.
02
Canada and project conversion
Canada connected project visibility, finance and international cooperation
Investment Summit63 opportunities
Mining and metals led the prospectus
Inclusion creates visibility for investors but does not constitute
approval, financing or a final investment decision.
TD Bank GroupC$150B
Five year financing commitment
The commitment includes critical minerals and resources alongside
several other sectors and financing activities.
MarathonC$1.3B
Construction stack assembled
The package combines public and private capital, equipment leasing,
streaming and a proposed Glencore processing route.
Canada / NorwayJoint mapping
Public geology before project pipelines
The geological surveys will exchange expertise and cooperate on
critical minerals mapping as a basis for future projects.
Canada also proposed a minerals and processing partnership with Europe.
The Summit closing announcement reported nearly C$500 billion in economy
wide commitments. Neither amount should be treated as a mining allocation.
Reading
Canada has widened the pipeline around its mineral base. The project
level evidence will come from due diligence, binding capital,
purchase agreements, construction decisions and operating delivery.
What follows
Marathon closings and board sanction, Ontario documentation,
Summit mandates and project level outcomes from the European and
Norwegian partnerships.

05
Ownership, buyers and strategic control
Institutions moved closer to the decisions that govern access and control
European UnionCommon buyer planned
Raw materials corporation
Procurement and stockpiling entered Europe’s industrial security agenda,
while mandate, funding and purchasing rules remain undefined.
European Union / BrazilObjections issued
MMG nickel acquisition review
Formal objections bring competition, ownership and industrial access
into the same transaction review. They are not a final prohibition.
Greenland / Denmark / U.S.Agreement anticipated
Sensitive investment questions
The security plan may address investment conditions, but the legal text
and definitions were not available for review during the week.
United States · Searles ValleyDefinitive asset deal
Boron and brine platform
5E signed an agreement for operating assets, while court approval,
railway authorization, bridge finance and closing remain ahead.
Reading
Strategic value can change through buyer design, transaction review,
security rules and ownership transfers even when the mineral resource
remains in the same place.
What follows
The EU corporation mandate, the MMG response and final decision,
publication of the Greenland agreement and completion of the Searles assets.
