Up to 18.5% Copper & 34.8% Zinc in initial pXRF readings* on drillcore
Golden Deeps Ltd (ASX: GED) is pleased to announce the intersection of significant sulphide mineralisation in all three completed diamond drillholes at its 100% owned Havilah Project in the Lachlan Fold Belt Copper-Gold Province of central NSW (see Figure 1, below, and regional location, Figures 3 and 4).
- Thick copper and zinc sulphide mineralisation has been intersected in diamond drilling of key targets at the Company’s Havilah Project in the world-class Lachlan Fold Belt Copper-Gold Province of NSW1,2 (see Hazelbrook Prospect plan - Figure 1, cross section - Figure 2 and location plans - Figures 3 and 4).
- Diamond drillhole HVD003, which tested the extensive Hazelbrook copper soil and rockchip (>1% Cu) anomaly3, intersected patches of semi-massive copper (chalcopyrite) and zinc (sphalerite) sulphides as well as vein and disseminated sulphides across an 80m zone in the targeted Sofala Volcanics (see Image 1 showing the sulphide mineralisation; Appendix 1 for drillhole details & Appendix 2 for descriptions of mineralisation).
- The mineralised intersection in HVD003 included a 28m zone (from 85.8m) of more intense sulphide mineralisation which produced high-grade portable XRF (pXRF) readings of up to 18.5% Cu and 34.8% Zn, averaging 0.5% Cu and 0.7% Zn* (see Appendix 3 for full tables of pXRF readings and Cautionary Note below).
- Diamond hole HVD001, which tested the Hazelbrook North Cu-Zn-Au anomaly3, intersected 40m of silicified breccia/veining and disseminated sulphides (py +/-cpy, sph) from surface, and HVD002, which tested a strong Induced Polarisation (IP) anomaly1, intersected a 130m zone of altered mafic volcanics with scattered veinlets and disseminations of pyrite and rare chalcopyrite (see Figure 1, location, and Appendix 2, descriptions).
- The diamond drilling program continues with HVD004 testing the Hazelbrook anomaly 200m along strike to the northeast of HVD003, again under rockchip sample values of >1% Cu3 (see Figure 1).
Image 1: HVD003, 85.8m to 86m: semi-massive sulphide patches of copper sulphide - chalcopyrite (cpy) and zinc sulphide - sphalerite (sph) in Ordovician mafic volcanics (pXRF readings up to 18.5% Cu, 34.8% Zn* – see Appendix 3)
*Cautionary Note in relation to disclosure of visual estimates and pXRF readings described in this release and detailed in Appendix 2 and 3 respectively: The Company cautions that visual estimates of sulphide mineralisation abundance and pXRF readings should never be considered a proxy or substitute for laboratory analyses. Laboratory assays (ICP MS/OES and Fire Assay for gold) are required to determine representative grades and intervals of the elements associated with the visible mineralisation reported from geological logging and pXRF readings. Core is being sampled for submission to ALS laboratories in Orange, NSW. Laboratory analytical results are expected within 3 to 6 weeks.
Golden Deeps CEO Jon Dugdale commented: “The intersection of sulphide mineralisation in all three initial holes at Havilah, including thick zones of copper and zinc sulphide mineralisation in HVD003, indicates we’re on top of a large porphyry-sulphide system with similar characteristics to other major copper-gold discoveries in the Lachlan Fold Belt such as Cadia-Ridgeway and the recent Boda-Kaiser discovery.
“We look forward to completing the remainder of our diamond drilling program and receiving the laboratory results from the holes completed, which will be released as soon as they come to hand and are compiled.”

The third hole of the program, HVD003, tested the Hazelbrook target where an extensive northeast-southwest trending copper-zinc soil anomaly has been defined with rockchip values of over 1% Cu3 (Figure 1).
HVD003 intersected a sulphide mineralised zone from 85m to 119m which included patches and stringers (averaging 1-2%) of the copper-sulphide - chalcopyrite and the zinc-sulphide - sphalerite. These patches occur within extensively altered (Ordovician) mafic volcanic/volcanoclastic rocks with disseminated chalcopyrite-sphalerite-pyrite mineralisation which occurs from 85m to 166m (over 80m) (see Appendix 2).
The mineralisation aligns with the surface soil and rockchip copper-zinc anomaly, striking northeast, dipping to the northwest, and the drilling intersection approximating true width (see cross section, Figure 2, below).

What's the Next US Copper Mine? 26 Copper Projects to Watch
Companies with upcoming copper mines in the US could be poised to benefit from tailwinds in the sector, including the new administration promising to cut "red tape" for critical minerals projects.
Copper demand is climbing quickly in recent years because of the rapid urbanization of the global south as well as the developing energy transition sectors. However, current copper mines are increasing in age and there is a lack of new copper mines to replace them, both due to limited greenfield exploration and long permitting times.
This has put the world's copper supply in a difficult situation, and experts expect to see deficits begin to emerge in 2025.
Resource nationalism is also increasing in recent times, with countries heavily focused on building their own critical minerals supply chains. This caused the Biden administration to list copper as a critical mineral in late 2024, which would allow projects accelerated permits, investment incentives and national security enhancements.
Additionally, after new US President Donald Trump took office in January 2025, Trump issued an executive order that would slash red tape to increase domestic critical mineral production, including copper. The move has caused significant environmental concerns, but it could support US copper companies that have previously struggled to receive permits.
In this article we dive into more than 25 US copper projects in the construction, restarting or permitting phase, based on data from mine database Mining Data Online (MDO). MDO's database focuses on publicly traded mining companies, so there may be US copper mines being developed by private companies that are not in this list.
This article is based on data provided by MDO as of March 2025.

Next US copper mine: Copper mines under construction
Black Butte project
Ownership: 87% – Sandfire Resources (TSXV:SFR)
Mine type: Underground
Deposit type: SEDEX, Stratabound
Once it enters production, the Black Butte copper project in Montana is expected to produce 120,000 metric tons (MT) of copper concentrate annually. The site’s Johnny Lee deposit hosts proven and probable reserves of 8.8 million MT, containing 226,100 MT of copper at a grade of 2.6 percent.
Sandfire had previously begun Phase I construction to mine the Johnny Lee deposit, but a Montana district court ruling overturned the prior Record of Decision in 2022 halted it. However, the Montana Supreme Court ruled in Sandfire’s favor in Q1 2024. With its mining permit reinstated, the company is now assessing Black Butte’s economics as it moves toward a final investment decision.
Florence project
Ownership: Taseko Mines (TSX:TKO,NYSE:TGB)
Mine type: In-Situ
Deposit type: Porphyry
Located in Central Arizona, the Florence project is expected to produce 85 million pounds of copper annually. According to MDO, Florence will be one of the world's most efficient copper producers, and copper produced on site will meet the London Metal Exchange grade A standard.
Overall, the site's proven and probable mineral reserves are 2.32 billion pounds of contained copper from 320 million MT of ore with an average grade of 0.36 percent copper. Construction at the site reached the 56 percent mark in December of 2024 and is on track for its first production by the end of 2025.

The Idaho Cobalt Operation (ICO) is located in Northern Idaho near the border with Montana. Even though the project is focused on cobalt production, over the seven-year life of the mine, it is planned to produce more than 15,000 MT of copper.
While the ICO is still listed as under construction, Jervois Global halted development of the mine in March 2023 due to falling cobalt prices. As of Q4 2024, construction activities remain suspended and the company is focused on maintenance and environmental compliance.
Next US copper mine: Mines being restarted
Gunnison mine
Ownership: Gunnison Copper (TSX:GCU,OTCQB:GCUMF)
Mine type: In-Situ Recovery, Open Pit
Deposit type: Skarn
Gunnison Copper, previously named Excelsior Mining, is currently developing its Gunnison mine in Arizona as an open pit mining operation. Gunnison was originally scheduled to begin operating in 2020 as an in-situ recovery project, but startup was delayed due to low flow rates. Gunnison Copper has been evaluating different alternatives to overcome the challenges and obtained permits to begin well simulation using small-scale, shallow-level hydraulic fracking.
However, the company determined that an open-pit operation has "substantially improved viability" compared to the ISR operation at this time, and is now advancing the permitting process for the open pit. Gunnison intends to maintain the option of its fully permitted ISR operation and well stimulation.
Once the open-pit mine is in operation, Gunnison estimates an average annual production of 167 million pounds of copper cathode. The probable mineral reserve for the in-situ operation as of 2016 is 4.5 billion pounds of copper from 782.2 million MT of ore with an average grade of 0.29 percent. The open pit's 2024 mineral resource estimate showed a measured and indicated resource of 5.1 billion pounds of copper from 831.6 million MT of ore with an average copper grade of 0.31 percent.
Sunshine mine
Ownership: Sunshine Silver Mining and Refining

Since then, Northern Dynasty has been suing to overturn the rejection.
In February 2025, court proceedings were suspended for 90 days at the request of the Environmental Protection Agency (EPA) and the USACE. This followed the confirmation of a new EPA administrator and Trump's executive order supporting critical mineral projects. However, it still remains to be seen whether the Trump administration will support Pebble this time around, as the previous rejection was made during his first term.
Pebble is planned to produce an estimated average of 320 million pounds of copper concentrate annually, from a measured and indicated resource base of 52.99 billion pounds of copper.
Pumpkin Hollow
Ownership: Kinterra Capital
State: Nevada
Mine type: Open pit
Deposit type: Skarn, breccia pipe/stockwork, iron oxide copper-gold (IOCG)
Commodities: Copper, gold, silver
The Pumpkin Hollow project hosts a fully permitted open pit project and a fully permitted and constructed underground mine. Production and development were suspended at the operations after its previous owner Nevada Copper filed for Chapter 11 bankruptcy in June 2024. That October, Pumpkin Hollow was acquired for US$128 million by an affiliate company of private equity firm Kinterra Capital, which plans to advance the assets.
Proven and probable copper reserves at Pumpkin Hollow's open pit project total 3.59 billion pounds from 385.7 million MT of ore with an average grade of 0.47 percent copper. The open pit is expected to produce an annual average of 163 million pounds of payable copper. Additionally, the underground mine is projected to produce 50 million pounds of payable copper annually once it is restarted.

Deposit type: Porphyry
Commodities: Copper, molybdenum, silver
The Resolution project has the potential to supply 25 percent of the total US copper demand, with planned production of 40 billion pounds of copper over its 40 year mine life.
Permitting for the project has been underway for over a decade, and the US Forest Service published and then rescinded the project's final environmental impact statement in early 2021. The local Apache Tribe has taken legal action to stop the proposed mine as the deposit sits under a site of religious importance.
According to BHP's 2024 annual report, the Resolution joint venture and the US Forest Service are focused on further consultation with Native American Tribes to mitigate harm to the region. The agency has said there is currently no timeline for republication of the final environmental impact statement. After Trump took office in January, Rio Tinto's CEO said he is optimistic the president will grant Resolution's final permits.
Tamarack North project

State: Minnesota
Mine type: Underground
Deposit type: Magmatic
Commodities: Copper, nickel, platinum, palladium, gold, silver, cobalt, lead
Twin Metals Minnesota's development is currently on hold after hitting multiple roadblocks, including the rejection of its mine plan and cancelling of two federal mining leases due to concerns tailings from the mine will impact the Superior National Forest and Boundary Waters Canoe Area.
In 2022, Antofagasta's subsidiary Twin Metals engaged in litigation against the US government over the actions, and in September 2023, the district court dismissed the company's claims, siding with the government. Twin Metals filed an appeal in November of that year.
If approved, the mine is expected to produce 158,000 MT of copper annually. The company said it is studying the possible impact of Trump's executive order.
Van Dyke project
Ownership: Copper Fox Metals (TSXV:CUU,OTCQX:CPFXF)
State: Arizona
Mine type: In-situ
Deposit type: Porphyry, breccia pipe/stockwork, vein/narrow vein

Top 5 Canadian Mining Stocks This Week: Euro Sun Gains 54 Percent as Copper Hits New High
Welcome to the Investing News Network's weekly look at the best-performing Canadian mining stocks on the TSX, TSXV and CSE, starting with a round-up of Canadian and US news impacting the resource sector.
The US Bureau of Economic Analysis released February personal consumption expenditures (PCE) index data on Friday (March 28). The figures show inflation increased 2.5 percent on an annualized basis in February, aligning with analyst expectations and reflecting no change from the 2.5 percent recorded in January. On a monthly basis, inflation rose by 0.3 percent, also matching January’s increase.
However, core PCE, which excludes the volatile food and energy prices, increased 2.8 percent year-over-year and 0.4 percent month-over-month. Both came in above analyst expectations of 2.7 and 0.3 percent, respectively.
The PCE is the Federal Reserve's preferred measure for tracking inflation and will be significant when it meets next in May. Combined with recent consumer price index figures, the data indicates progress has stalled in bringing inflation to the Federal Reserve's 2 percent target rate.
To the north, Statistics Canada released January gross domestic product (GDP) numbers on Friday. The report shows that GDP grew by 0.4 percent in January, up from a 0.3 percent increase in December.
The largest gain was observed in goods-producing industries, which rose 1.1 percent, marking the highest increase since October 2021. As for Canada’s resources, the mining, quarrying and oil and gas extraction sector increased by 1.8 percent during the first month of the year. This increase was driven by a 2.6 percent rise in the oil and gas extraction subsector. However, metal ore mining declined by 1.2 percent.
The agency also provided a brief estimate of February’s GDP numbers, as well as a look at Canada and the US’s metal manufacturing trade. Tariff threats from the United States appear to have kept numbers flat, as preliminary real GDP data is “essentially unchanged in February.” Official data for February will be released on April 30.
Markets and commodities react
In Canada, markets were in the red this week. The S&P/TSX Composite Index (INDEXTSI:OSPTX) fell 1.2 percent during the week to close at 24,759.15 on Friday, the S&P/TSX Venture Composite Index (INDEXTSI:JX) decreased 1.04 percent to 633.63 and the CSE Composite Index (CSE:CSECOMP) dropped 2.43 percent to 121.13.
US equity markets fell even further this week. The S&P 500 (INDEXSP:INX) lost 2.4 percent to close at 5,5680.95, the Nasdaq 100 (INDEXNASDAQ:NDX) dropped 3.79 percent to 19,281.40 and the Dow Jones Industrial Average (INDEXDJX:.DJI) shed 1.41 percent to 41,583.91.
The gold price climbed to fresh all time highs this week gaining 2.02 percent to US$3,084.48 per ounce at 5:00 p.m. EDT Friday. The silver price rose higher with a 3.29 percent increase during the period to US$34.10.

FAQs for Canadian mining stocks
What is the difference between the TSX and TSXV?
The TSX, or Toronto Stock Exchange, is used by senior companies with larger market caps, and the TSXV, or TSX Venture Exchange, is used by smaller-cap companies. Companies listed on the TSXV can graduate to the senior exchange.
How many companies are listed on the TSXV?
As of June 2024, there were 1,630 companies listed on the TSXV, 925 of which were mining companies. Comparatively, the TSX was home to 1,806 companies, with 188 of those being mining companies.
Together the TSX and TSXV host around 40 percent of the world’s public mining companies.
How much does it cost to list on the TSXV?
There are a variety of different fees that companies must pay to list on the TSXV, and according to the exchange, they can vary based on the transaction’s nature and complexity. The listing fee alone will most likely cost between C$10,000 to C$70,000. Accounting and auditing fees could rack up between C$25,000 and C$100,000, while legal fees are expected to be over C$75,000 and an underwriters’ commission may hit up to 12 percent.
The exchange lists a handful of other fees and expenses companies can expect, including but not limited to security commission and transfer agency fees, investor relations costs and director and officer liability insurance.
These are all just for the initial listing, of course. There are ongoing expenses once companies are trading, such as sustaining fees and additional listing fees, plus the costs associated with filing regular reports.
How do you trade on the TSXV?
Investors can trade on the TSXV the way they would trade stocks on any exchange. This means they can use a stock broker or an individual investment account to buy and sell shares of TSXV-listed companies during the exchange's trading hours.

Copper Prices Surpass US$10,000 as US Tariff Fears Shake Global Markets
Copper prices surged past US$10,000 per metric ton on Thursday (March 20), hitting a five month high as traders scrambled to secure supply ahead of potential US tariffs on the base metal.
London Metal Exchange (LME) copper futures climbed sharply in early trading, reflecting a combination of supply constraints, rising demand and uncertainty surrounding trade policy.
US President Donald Trump has ordered a probe into the national security implications of copper imports, raising concerns that a 25 percent tariff could be imposed, similar to levies already placed on aluminum and steel.
The potential for such tariffs has triggered a wave of preemptive buying, particularly in the US, where traders are paying record premiums to acquire copper before any duties take effect. The spread between New York Comex futures and LME prices widened to more than US$1,254 this week, exceeding February’s high of US$1,149.
Tariff threat complicating copper trade
If the US imposes a 25 percent tariff on copper imports, analysts say the price gap between Comex and LME copper could widen even further, potentially surpassing US$2,000.
StoneX analyst Natalie Scott-Gray told the Financial Times that this would further distort global copper trade, creating strong incentives for suppliers to shift even more metal to the US market.
Wei Lai, deputy trading head at Zijin Mining Investment Shanghai, told Bloomberg that “a round of cross-regional repricing triggered by potential US tariffs" is unfolding. The rush to divert supply to the US is leaving other regions short of the metal, while also boosting investor confidence in copper as a lucrative commodity.
Beyond tariffs, the copper market is facing broader supply-side challenges. Processing fees for copper smelters have reached historic lows, raising concerns about the long-term viability of some refining operations. An oversupply of smelting capacity — particularly in China — has made it difficult for copper smelters to maintain profitability.
Commodities trading giant Glencore (LSE:GLEN,OTC Pink:GLCNF) recently announced it would halt operations at its Philippine copper smelter, citing “increasingly challenging market conditions” as processing fees collapsed.
More smelters could shut down if the situation persists, further tightening copper supply and boosting prices.
While trade policy is a key factor driving copper’s price surge, broader macroeconomic trends are also playing a role. Expectations of rising demand from Germany’s major infrastructure and military spending initiatives, as well as stimulus measures in China, are supporting bullish sentiment for the metal. Furthermore, some investors are diversifying away from US tech stocks, shifting funds into gold and industrial metals as a hedge against economic volatility.
During the recent Prospectors & Developers Association of Canada convention, Adrian Day, president of Adrian Day Asset Management, explained why US tariffs on copper imports would be a bad idea.
"Logically, if you're worried that we need a lot of copper in the US and we're not producing enough, the last thing you want to do is put tariffs on shipments from abroad," Day explained. "I suspect that the people making a recommendation will recommend no tariffs, and they'll recommend encouraging domestic production, and so on."
Rising copper prices boost China's Zijin
The positive impact of higher copper prices is already being felt across the mining sector.
Zijin Mining Group (OTC Pink:ZIJMF,SHA:601899), China’s largest metals producer, reported a 52 percent jump in profit last year, driven by increased output and soaring prices for copper and gold. The company posted net income of 32.1 billion yuan (US$4.4 billion), with revenue climbing 3.5 percent to 303.6 billion yuan.
Despite these gains, Zijin recently lowered its copper output target for 2025 by about 6 percent to 1.15 million metric tons, citing regulatory hurdles and geopolitical challenges that have slowed its overseas expansion. Resistance to Chinese acquisitions in western markets has also played a role in the company’s revised projections.
Market waits for copper probe results
For now, the outlook for copper is uncertain as traders await the results of the US tariff investigation.
While final recommendations are unlikely to come until later this year, major investment banks, including Goldman Sachs (NYSE:GS) and Citigroup (NYSE:C), expect 25 percent import duties on copper by the end of 2025.
In the meantime, copper prices are likely to remain volatile.
As of midday on Thursday (March 20), LME copper was trading just below US$10,000, with other base metals showing mixed performance. Aluminum remained slightly higher, while nickel was steady.

Hillgrove Accelerates Nugent Copper Deposit Development, Raises AU$16 Million
Hillgrove Resources (ASX:HGO,OTC Pink:HLGVF) said on Monday (March 17) that it is accelerating development of the Nugent deposit at its Kanmantoo copper mine after raising AU$16 million.
The company secured AU$13 million through a placement to institutional and sophisticated investors, and raised AU$3 million via a share purchase plan that was open to existing shareholders.
"Following the success of the recent excellent Nugent drilling results, our technical team have identified a path to accelerate the Nugent production profile,” said CEO and Managing Director Bob Fulker in a March 5 release.
Fulker was referring to results from a recent drilling program at the South Australia-based operation, including 18.55 metres at 5.69 percent copper and 1.02 grams per tonne gold — significantly higher than the resource grade.
“This acceleration will allow the Kanmantoo underground mine to increase production up to 1.8Mtpa, with increased production of copper units and a material consequential decrease in our unit costs," he added.
The company said the target expansion for the mining and processing rate is approximately 25 percent, noting that it expects to see changes within the first six months of 2026.
Hillgrove also said it has entered into relevant key contracts to start work on the decline to access ore.
Its existing contractor, PJL, will supply and maintain the requisite mining equipment, while construction engineering company Redpath will provide labour for the project. Both contractors are scheduled to start work in April.
Located approximately 55 kilometres from Adelaide, Kanmantoo operated as a series of open pits from 2010 to 2020. Hillgrove began underground mining at the site in May 2023, declaring commercial production in July 2024.
The project has three production areas: Kavanagh, Spitfire and Nugent. The first two are currently in operation.
“Having three active mining areas will increase the efficiency and flexibility of underground mining operations at Kanmantoo as well as providing a more diversified base of feed to our plant,” Fulker added.
Hillgrove successfully restarted the 3.6 million tonne per year processing plant at the site in 2018.
First ore processing from Nugent is anticipated in the fourth quarter of 2025, while ore from the deposit is expected to be delivered to the plant in the first half of 2026. It plans to complete 60,000 metres of drilling at the site this year.
Copper attracting attention in Australia
In an interview with the Investing News Network, Guy Le Page, director at RM Corporate Finance, said that copper, uranium and select critical minerals are currently gaining attention in Australia.
The red metal is a strategic element in the country's road to net zero, as it is often used for renewable energy innovations such as electric vehicles, wind turbines and solar panels.
Mining giant BHP (ASX:BHP,NYSE:BHP,LSE:BHP) is projecting a 70 percent increase in copper demand by 2050, giving Hillgrove and other companies more reasons to boost their output of the key commodity.

Kiribati Explores Deep-Sea Mining Deal with China Amid Global Regulatory Talks
Kiribati is reportedly in discussions with China to explore deep-sea mining opportunities, signaling a potential shift in its approach to tapping into its vast offshore mineral resources.
The Pacific island nation holds the exploration rights to a 75,000 square kilometer area in the Pacific Ocean, a region believed to contain valuable deposits of cobalt, nickel, and copper — key materials for the global battery industry.
The talks between Kiribati and Chinese officials come after the collapse of a previous agreement with the Metals Company (TMC) (NASDAQ:TMC), a Canada-based deep-sea mining outfit.
TMC confirmed that the contract was terminated "mutually" at the end of 2024, stating that Kiribati's mining rights were "less commercially favourable than (its) other projects" with Nauru and Tonga.
In a Monday (March 17) statement, the Kiribati government described discussions with Chinese Ambassador Zhou Limin as "an exciting opportunity" to explore ways to potentially collaborate on exploring Kiribati's deep-ocean resources.
A fisheries official confirmed the government is seeking new foreign partners to advance its deep-sea mining ambitions.
Kiribati's engagement with China aligns with Beijing's broader push to secure access to critical minerals in the Pacific.
In February, China struck a five year deal with the Cook Islands to cooperate on seabed exploration, although the agreement does not include any mining or exploration licenses.
For its part, Kiribati has taken steps to deepen its ties with China in recent years, severing diplomatic relations with Taiwan in 2019. Since then, Chinese companies have gained rights to exploit Kiribati's profitable fisheries, and Chinese police personnel have visited Tarawa, the country's capital, to train local security forces.
Opposition leader Tessie Lambourne has expressed concerns about China's growing influence on Kiribati, stating, "I always say that our government is bending over backwards to please China."
While Kiribati and other Pacific island nations, such as Nauru, view deep-sea mining as a potential economic boon, opposition remains strong among some regional neighbors.
Palau, Fiji and Samoa have called for a moratorium on the industry, citing significant environmental concerns.
Global regulatory talks underway on deep-sea mining
Companies looking to exploit the seabed are targeting polymetallic nodules — rock-like formations rich in manganese, cobalt, copper and nickel. However, scientists warn that large-scale mining could have irreversible consequences for marine ecosystems, potentially disrupting poorly understood habitats.
The future of deep-sea mining is currently under debate at the International Seabed Authority (ISA), a United Nations-affiliated body responsible for regulating seabed resources beyond national jurisdictions.
The Council of the ISA convened on Monday in Kingston, Jamaica, for two weeks of intensive negotiations aimed at finalizing regulations that would govern seabed mineral exploitation.
One key agenda item involves determining regulatory scenarios in case a country submits an application for seabed exploitation before formal rules are established. Delegations from Nauru and Chile were given additional time to agree on this issue, with discussions scheduled for March 28.
The Council of the ISA is also reviewing a revised draft of the exploitation regulations, focusing on environmental standards and benefit-sharing mechanisms.
A high-level discussion on the draft standards and guidelines is set for March 27. It will help determine which documents are ready for finalization, and which require further updates from the Legal and Technical Commission.
