China has announced new export controls on tunnel boring machines (TBMs), a significant development for the global tunneling, infrastructure and mining industry. Announced on the 19th of October 2026, the measures are due to take effect on the 18th of November.
Click below link for a fresh and clear explainer on energy demand from mine-to-metal which highlights the physical reality that ore grade and processing route dominate energy use.
This is especially critical for strategic metal supply, especially domestic copper production - example @ivanhoeelectric Santa Cruz Copper Mine under development in Arizona that’s mentioned in the link below.
Excellent work by Director @MBazilian and the team at the @payneinstitute @coschoolofmines for this data driven report.
Proud to be class of 2000 @coschoolofmines grad in Geology & Geological engineering and to serve on the Industrial Advisory Board at the @payneinstitute where this type of analysis originates.

Bravo @TaylorMelvin_IE excellent interview 🔝🪨⛏️
Ivanhoe Electric CEO Taylor Melvin shared his insights into future copper demand, valuations and our Santa Cruz Copper Project in Arizona in an interview with CNBC to mark the start of London Metal Exchange Week.
“A year ago going into LME, we were just coming into almost five-dollar copper and a year later here we are at, close to $6.66 a pound,” he said on @CNBC’s Squawk Box Europe. “Most projections currently talk about higher copper prices needed to incentivize the projects that we need to meet global demand, so it certainly is a very good time to be in this industry.”
While copper prices and miner valuations may fluctuate on concerns over the financing of copper-intensive mega projects such as AI data centers, a significant slowing of long term demand is unlikely, he said.
“It's hard to think that one of these large scale technology companies is going to make an investment decision on a hyperscale data center based on the cost of copper,” he said. “And that same inelasticity applies to another demand pocket that's emerging, which is national security, national defense budget.”
It’s not uncommon for copper producers to see a disconnect between their stock valuation and the intrinsic value of their assets, he said. “There's definitely a disconnect between the current valuation and our shares and the intrinsic value of our assets,” he said. “We're in the development stage of a very important and very high-quality asset in the United States.”
Ivanhoe Electric’s Santa Cruz Copper Project is designed to produce 99.99% pure copper cathode over a 24-year mine life with average annual production of about 75,000 tonnes of copper cathode.

🚨 ATOMIC EAGLE LANDS MASSIVE 116M LB NIGER URANIUM DEAL
Atomic Eagle ( ASX: $AEU.AX ) has officially resolved its West African expropriation dispute, securing a 60/40 joint venture with the Republic of Niger to develop the Tier-1 Madaouela Uranium Project while withdrawing all pending international arbitration.
Is this commercial resolution a new blueprint for navigating sovereign risk in critical minerals?
Govind Friedland retweeted
Atomic Eagle (ex GoviEx) got their Niger licence back.60% Atomic Eagle - %40 Niger mining convention.
#uranium
It’s been 781 days of blood, sweat and tears since 4 July 2024, when GoviEx was first notified that the Niger Government had withdrawn its rights to the Madaouela mining permit.
I’m enormously proud of my team at GoviEx Uranium — and now @AtomicEagleASX — for our relentless perseverance and never-give-up attitude.
We acquired, funded, explored, developed and permitted one of the largest and highest-grade uranium projects in Africa… lost it… and have now re-acquired it.
Transformational day for @AtomicEagleASX Atomic Eagle 🦅☢️
Atomic Eagle Limited has reached an agreement with the Republic of Niger to re-establish its interest in the Madaouela Uranium Project, which was expropriated from previous holder GoviEx Uranium Inc in 2024.

“The residual is already negative.
Net zero was never a plan — it was a spreadsheet with no bill of materials.” Craig Tindale @ctindale nailed the analysis 🎯
@ivanhoeelectric is part of America’s solution with pending domestic copper production.
Proud of my father @robert_ivanhoe delivering this message at today’s American Mining Roundtable with @POTUS :
“This is a truly historic occasion to bring America back to the leadership of mining, which built this building and which built this country. We’ve been sleepwalking through many administrations, and this is a revolution that will just electrify the millions of people in the United States that understand that everything you touch, we either mine it or we grow it agriculturally… So this is critical to our national security. We’re elated with your support, and we’re gonna use Yankee ingenuity to prove that we can dominate the supply chain again.”
Securing resilient critical minerals supply chains starts here. 🇺🇸
@ivanhoeelectric and ALL of its stakeholders will benefit from strong US Government support for its Santa Cruz Copper Project in Arizona 🪨 ⚒️
Bravo @realDonaldTrump @robert_ivanhoe @ivanhoeelectric for coming together in such an amazing way to make American Mining Great Again! 💪🏻🇺🇸🔝
At the American Mining Roundtable, earlier today @realDonaldTrump announced that and the @EximBankUS is working to provide more than $1 billion to finance @ivanhoeelectric’s Santa Cruz Copper project in Arizona.
Santa Cruz will be America’s next, major, long-term domestic producer of refined copper, strengthening U.S. supply chain independence and reducing our country’s reliance on imported refined copper.

I’m super excited to share Villa Treville’s reintegration of Villa Maura, reimagined by the talented Antonio Girardi, honoring Franco Zeffirelli’s visionary legacy while enhancing the magic of this iconic Positano refuge.
Coinciding perfectly with the launch of our new Assouline book Villa Treville Positano (co-authored by me with Nicky Swallow), it captures the soul and emotions of this extraordinary place, where the theatrics of opera, cinema, art, and the Amalfi Coast’s timeless beauty come together.
A true dream world on the cliffs.
The press is starting to take note:

If you follow @ctindale you know he’s an absolute genius that truly understands the true confluence of energy, raw materials and geopolitics. His commentary on @IPulseGroup is spot on.
If you’re interested in the future of mining or energy you need to stop here and make sure you understand the implications here . I-Pulse technology changes everything
The semiconductors I-Pulse is developing under today’s announced $250 million award are high-temperature, high-performance silicon-carbide (SiC) based components, specifically high-current, high-voltage solid-state switches and related packaging/capacitors. These are not standard chips. They are specialized power electronics engineered to survive and operate in extreme conditions (high heat, mechanical shock, high voltage/current) where conventional silicon semiconductors would fail.
Their core purpose is to enable I-Pulse’s proprietary pulsed power technology at commercial scale.
Pulsed power is the third and most efficient way to use electrical energy, we had AC , DC and now “pulse”. It works by taking a small amount of stored energy and repeatedly compressing/releasing it in extremely short, powerful bursts (e.g., cell-phone-battery-scale energy released at nuclear-plant-equivalent power levels in under 10 millionths of a second). Yeah I said nuclear power plant output from an iPhone battery for a minuscule amount of time .
Deep Geothermal Drilling is a game changer . It’ll rival nuclear or ellipse nuclear .
How it works: The high-temperature SiC switches deliver extremely high-power electrical pulses to hot granite and other geothermal formations ahead of the drill bit. These pulses fracture and soften the rock, dramatically increasing drilling speed , depth and cost
Outcome = Massively reduced drilling costs which is the biggest barrier to deep geothermal development. This unlocks the world’s untapped hot dry rock geothermal resources for next-generation advanced geothermal power plants. It being on par with Nuclear
Why it matters: Geothermal provides 24/7 baseload, dispatchable, secure, low-cost, carbon-free power (unlike intermittent solar/wind). re industrial.
It’s literally using the earth as a nuclear power plant -we have unlimited solar energy and we have unlimited earth heat , high-temperature semiconductors and capacitors are required for this new hyper disruptive drilling technology to function in extreme downhole conditions.
Other Applications Enabled by These Semiconductors a also revolutionary
Mining & Critical Minerals : Pulsed power rock breaking/crushing (more energy-efficient, potentially higher recovery rates by fracturing along mineral boundaries).
Defense Systems : High-power pulsed applications in harsh conditions.
Manufacturing, Disruptive high-speed/precision welding, metal-forming, and crimping at industrial scale.
Mineral & Water Exploration : Non-invasive high-definition detection methods.
Agriculture : Crop protection applications. Electrical herbicide , easy to apply to broad acre crops and more effective than chemicals
Future/Long-term — Efficient high-power systems for space colonization (Moon/Mars), as noted in the release.
Strategic & National Impact (Per the CHIPS Award)
If we can accelerate zero carbon geothermal globally it’ll literally change the world as much as technology we have seen in civilisation to date .
businesswire.com/news/home/2…
Major move for the global leader in pulsed power: @IPulseGroup acquires CSI Technologies of California, bringing high-energy, high-voltage capacitor expertise in-house.
This strengthens our domestic supply chain for defense manufacturing, critical fusion components, next-generation geothermal, mining, and agricultural applications.
This acquisition accelerates scalable clean-tech solutions that lower costs and unlock critical natural resources without compromise.
High-impact energy and materials technology—built in the USA 🇺🇸
Excited to share this breakthrough in sustainable agriculture! 🚜⚡
I-Pulse has launched iTerra — combining AI (95% accuracy in spotting weeds) with precision high-voltage pulses (just 5ms) to zap weeds at the root without chemicals, preserving soil health and enabling truly organic, regenerative farming.
No herbicides. No resistance issues. Healthier fields and food for the future.
Large-scale trials kick off Q2 2026.

The war on glyphosate is heating up: weed resistance is surging, regulations are tightening, and health concerns (including potential cancer links) keep growing.
Enter iTerra (an I-Pulse company): AI-powered vision (up to 95% accuracy in early trials) spots weeds vs. crops, while tractor-towed robotic wands deliver precision high-voltage pulses straight to the root in just 5 milliseconds, killing the entire plant permanently.
Unlike laser competitors (e.g., Carbon Robotics LaserWeeder), which often scorch leaves/meristems but leave roots alive, letting tough perennials regrow, iTerra eliminates weeds roots and all.
The dead plants stay in the soil, decomposing naturally as nutrients, adding compost and preserving soil microbiology for truly regenerative, organic farming.
No chemicals. No residues. Healthier soil, water, and food.
A real game-changer for farmers.

If an adversary seeks to conquer you, they begin at the base.
Power, liberty, freedom, and well-being rest on industrial capacity and materials. Defense systems, electrification, AI, energy, and Main Street all draw from the same metals, alloys, chemicals, and factories.
Control the matter and the machinery that shapes it, and you quietly inherit the power above it.
Freedom that depends on another nation’s mines, smelters, and factories lives on borrowed time. That clock has already been ticking for to long .
Time to act .
Missiles like the Tomahawk—and the advanced defenses against them—consume vast quantities of critical minerals far beyond just copper.
These systems increasingly depend on scandium-aluminum alloys to reduce weight, extend range, and enhance payload performance under extreme conditions.
That’s exactly why these are designated ‘critical raw materials’—national security hinges on secure, diversified supplies of scandium, rare earths, tungsten, gallium, and more.
I’m backing @surisemetals to help delivery the solution: innovative, responsible sourcing to meet this growing demand.

Strait of Hormuz isn’t just an oil chokepoint, it’s now strangling sulphuric acid supply, the hidden “master chemical” for processing, nickle, copper, cobalt, uranium & more.
The Middle East supplies ~24% of global sulphur (50% of seaborne trade), essential for acid used in HPAL nickel (Indonesia imports 75%, low inventories), African oxide copper leaching (~2Mt/y sulphur, 90% Middle East-sourced), DRC cobalt (70% global supply), & fertilizers (60% acid demand).
Disruption risks quick output cuts: some HPAL plants keep just 1-2 months inventory; oxide copper ops could close in ~3 weeks without acid.
As previously warned, traders are struggling to source any, prices are surging across Africa. Even before the Iran war started Zambia banned exports of sulfuric acid, and disruption of >3 weeks & copper oxide ops shut down.
This exposes the fragility: geopolitics + tight markets = cascading bottlenecks in electrification metals.
By contrast, the integrated sulfide copper producer @IvanhoeMines_ Kamoa-Kakula Project in the Democratic Republic of the Congo 🇨🇩 does not consume sulfuric acid, in fact produces huge amounts of it on-site as a by-product of smelting and sells to oxide copper producers and consumers who need it to heap leach and in their processing plants.
At scale Ivanhoe’s Kamoa smelter can produce >750,000t/year sulfuric acid while other operators face soaring costs or halt. This is a huge structural advantage for Ivanhoe Mines.
Build resilient, diversified chains now. Intention without physical security is illusion.
