Stake & Paper Editorial TeamMay 1, 2026
The Metals Company (TMC) announced today that NOAA has determined its consolidated application for an exploration license and commercial recovery permit under the Deep Seabed Hard Mineral Resources Act is in full compliance with federal requirements
, marking a watershed moment for the controversial deep-sea mining sector.
The determination follows substantial compliance in March and represents another key step toward a potential permit before the end of Q1 2027
.
The application covers a ~65,000 km² exploration and commercial recovery area in the Clarion Clipperton Zone, compared to a commercial recovery area of ~25,000 km² in TMC USA's initial commercial recovery permit application from April 2025
.
TMC: NOAA Backs Seabed Mining Plan
NOAA's determination that TMC USA's consolidated deep-seabed mining application is in full compliance with the Deep Seabed Hard Mineral Resources Act and its implementing regulations
advances the timeline for what could become the first commercial-scale polymetallic nodule operation in international waters.
TMC USA submitted the consolidated application earlier this year for polymetallic nodules in international waters of the Clarion Clipperton Zone in the Pacific Ocean
, an area rich in manganese, nickel, cobalt, and copper.
The application is informed by more than a decade of environmental baseline studies, scientific research and offshore engineering conducted by the Company and its partners
.
Following the public comment period, the EIS will be finalized and NOAA will make a final determination on whether to issue the license and permit, with TMC USA expecting the process will conclude before the end of Q1 2027
.
The regulatory milestone comes as demand for battery metals intensifies.
The consolidated application increases the commercial recovery area from ~25,000 to ~65,000 km², with an estimated resource of 619 million tonnes of wet nodules and a potential exploration upside of an additional 200 Mt
, according to the company's January filing.
Meridian Mining: $34M London Market Debut
Meridian Mining has applied for admission of its shares to the UK Financial Conduct Authority's Official List, with trading expected to begin May 1 under the ticker MNO
, the company announced this week.
Net proceeds from the offering are expected to be about £25 million ($33.8 million), which combined with existing cash of £55.1 million, will be directed toward development activities at Cabaçal
.
Meridian is focused on developing gold-copper assets in Brazil, led by its advanced-stage Cabaçal project in Mato Grosso state
.
The 2025 pre-feasibility study outlined a 10-year open-pit operation with an all-in sustaining cost of $742 per gold-equivalent ounce
, with
the company expecting a rapid 17-month payback on its initial investment
.
The Cabaçal project is a past-producing mine previously operated by BP Minerals and Rio Tinto
.
Beyond its flagship project, the company is pursuing a broader hub-and-spoke strategy across the Cabaçal volcanic massive sulphide belt, with exploration ongoing across a 50-km trend and the Santa Helena deposit identified as the next priority for drilling and development studies
.
Ur-Energy: Shirley Basin Uranium Production Begins
Ur-Energy announced the start of uranium mining operations at its Shirley Basin Project in Wyoming
, expanding U.S. domestic uranium production capacity at a critical moment for the nuclear fuel cycle.
Uranium bearing solution is now being captured from Mine Unit 1 at Shirley Basin after the successful completion of significant construction, wellfield installation, and permitting
.
The company expects to transport uranium loaded resin to Lost Creek for processing this summer, subject to an additional regulatory inspection and approval
.
The combined total annual licensed production and toll processing capacity of Lost Creek and Shirley Basin is 4.2 million pounds U₃O₈
.
Shirley Basin is historically the second largest uranium producing district in Wyoming, producing more than 51 million pounds of U3O8 from 1960 through 1992
.
In 1963, using acid leach mining methods, the site became the first commercially successful ISR mining operation in the United States
.
The restart comes as
the uranium market in 2025 has already fallen in deficit when investment demand is included, with uranium mine supply estimated to reach 160 million pounds, secondary supply approximately 25 million pounds, and investment demand approaching 10 million pounds – producing a deficit of 5 million pounds
, according to commodities-focused investment firm Goehring & Rozencwajg.
Kodiak and Teck: Arizona Copper Partnership
Kodiak Copper and Teck Resources would sell their respective Mohave and Copper Hill projects to Kay Copper, the new company, and in return receive 20 million shares of Kay Copper at a deemed price of C$0.25 per share
. The transaction creates a focused Arizona copper explorer at a time when
Arizona produced 70% of US copper production in 2025
.
Both Mohave and Copper Hill represent exploration-stage, drill-ready projects within Arizona's prolific mining districts
.
Mohave covers a 17-km² land package that includes two small-scale historic mines that operated in the 1950-60s, was last drilled in 2011, and has multiple soil/rock geochemical targets and geophysical anomalies that remain untested
.
Copper Hill is a 35-km² land package within a porphyry district near a producing mining cluster, saw limited historic exploration in the 1960-1970s during which three large porphyry centres were identified, with recent work by Teck highlighting multiple underexplored targets on the property
.
Teck is expected to be granted offtake rights with respect to certain concentrate production from the Mohave and Copper Hill projects, subject to definitive documentation
, giving the major a strategic position in future U.S. copper supply.
Uranium Supply Deficit Widens
The uranium sector is facing what analysts describe as a structural supply crunch that could persist for years.
2026 is poised to be transformative for uranium as tightening supply converges with robust demand from new reactor builds and life extensions, plus data center construction and a broader shift to clean energy
, according to a recent Nasdaq analysis.
Reactors are expected to consume about 68,900 metric tons of uranium in 2025, but by 2040, requirements will more than double to just over 150,000 MT in the reference case, and could exceed 204,000 MT in the high-growth scenario, with even the low case seeing demand topping 107,000 MT
, according to the World Nuclear Association.
For 2026, analysts estimate both uranium mine supply to be down and reactor demand to be up, producing an outright deficit in the global uranium market before investment demand is factored in
.
Uranium prices climbed above US$88 per pound in January 2026, representing approximately 10% appreciation since mid-December, driven by strengthening demand visibility and accelerating government policy momentum supporting nuclear power generation globally
.
Lion One Metals: $11M Financing Cancelled
Lion One Metals shares fell sharply after the company cancelled an $11 million financing that was intended to help with debt restructuring as it navigates both financial and operational challenges at its Tuvatu gold project in Fiji, according to the press release summary. The financing collapse underscores the funding challenges facing junior producers in volatile market conditions.
South32: Arizona Cost Blowout Shocks Market
South32 announced a more than 50% cost increase at its Arizona copper project, pushing first production at Taylor to late fiscal 2028 and extending the timeline to full capacity in fiscal 2031, according to the press release. The blowout highlights the inflationary pressures and execution risks facing major copper development projects in the United States.
What It Means
Today's announcements reveal three powerful themes shaping the mining sector: the race to secure critical minerals supply chains, the uranium market's structural tightening, and the growing appetite for copper exposure in premier jurisdictions.
TMC's regulatory progress represents a potential paradigm shift for battery metals sourcing, though environmental concerns remain. Meridian's successful London listing demonstrates continued investor appetite for near-term gold-copper producers in stable jurisdictions, particularly as
gold traded at $4,626/oz today, up 1.4%
according to market data. The Kodiak-Teck partnership signals that majors are willing to deploy capital into early-stage U.S. copper assets rather than compete for scarce advanced projects.
Most significantly, Ur-Energy's Shirley Basin restart and the broader uranium supply deficit narrative suggest the nuclear fuel cycle is entering a multi-year period of supply stress. With
artificial intelligence emerging as a major new driver of global electricity demand and a global investor survey showing that the rapid expansion of AI systems and hyperscale data centres is already reshaping long-term expectations for nuclear generation and uranium procurement
, uranium producers with permitted, shovel-ready projects are positioned to capture significant value.
The cancelled Lion One financing and South32's cost overruns serve as reminders that not all mining stories end well—execution, jurisdiction, and balance sheet strength matter more than ever in today's capital-constrained environment.
