Global Mining Review
The New Age Of MiningThe mining sector is undergoing a seismic shift. The industry is facing growing pressure from stakeholders to not only meet the increasing demand for critical materials, but to do so in a responsible, ethical, and sustainable way. At the same time, mining companies are navigating an increasingly complex geopolitical landscape. Meeting these demands and overcoming these challenges requires a new way of operating. At the heart of this evolution, inevitably, lies technology. From the initial steps of ore exploration to extraction and processing, emerging technologies are disrupting the entire mining ecosystem. This technological shift will define the future of the sector, and those organisations that successfully innovate will enhance their net present values and better balance competing demands.
Leading the way in this transformation is artificial intelligence (AI). From the first step of exploration and prospecting, AI can offer support. As AI devices can quickly process big data, the tools can identify possible mining sites with higher mineral potential more effectively than human surveyors alone. In fact, companies using AI in exploration have reported a 20 – 30% reduction in time and costs involved with mineral discovery.
Once the operation has launched, AI can deliver improved operational efficiency and safety. For example, AI-powered autonomous vehicles, which can also offer the advantage of being powered by green energy, are often used in hazardous areas to protect workers. This was successfully demonstrated by BHP’s Spence mine, which was BHP’s first fully autonomous site. The results speak for themselves: the Spence mine had zero incidents, and the autonomous operations reduced exposure to safety risks by 90%. Later in the mining process, AI can support with more accurate ore sorting, speeding up operations, maximising ore beneficiation, and reducing waste.
The use of digital twins and Internet of Things (IoT) sensors can add another layer of efficiency. By developing models of mine sites that use real-time geological data, engineers can simulate different mining strategies for optimal efficiency, sustainability, and safety. Digital twins can also be used to detect minor problems and prevent major problems, allowing for proactive maintenance measures to take place and reducing unexpected downtime. Workers can use wearable IoT sensors to monitor their health and detect exposure to dangerous gases or hazardous substances, which can alert them to any potential dangers. IoT devices can also be used to monitor environmental data, such as air and water quality, to ensure compliance with regulations.mining

Glencore Reinforces Commitment To Queensland MiningGlencore has reaffirmed its long-term commitment to Queensland mining, working to redeploy workers from its soon-to-close Mt Isa underground copper mine.
The company has invested $1.8 billion in its Queensland metals business over the past five years and has a strong focus on supporting employees amid the transition, with Mt Isa on track to close in July.
The mine has been operating for over 60 years, and the Mt Isa mine life has already been extended six years past its original life expectancy.
Glencore first spoke about closing the mine in October 2023, stating that the company had conducted a range of studies to extend the mine but found it wouldn’t be possible due to low ore grades and the lack of infrastructure to safely extract it.
Despite the scheduled closure of its Mt Isa underground copper operations in July, Glencore is minimising job losses while continuing to invest in its assets
“I want to make clear that Glencore is not going anywhere,” Glencore chief operating officer for Australian zinc and copper assets Sam Strohmayr said. “Mount Isa Mines is an important asset for Glencore globally and we’re continuing to invest in these operations.
“The future for our long-life George Fisher mine, which produces zinc, lead and silver, is bright.
“With its life of mine to 2042, we are upskilling our workforce, expanding production and advancing our fleet.”
The company has already transferred 89 people from the impacted underground copper operations to George Fisher, with 71 additional transfers pending as Glencore’s aim is to replace contractor fly-in, fly-out (FIFO) roles with local workers.
Glencore is also advancing a pre-feasibility study for its Black Star open cut project, which has the potential to provide 300–400 jobs from 2027.
If approved, the project will supply zinc, lead and copper ores to Mt Isa’s processing facilities.
While the closure of Mt Isa’s underground copper mine was initially projected to impact 1200 jobs, proactive workforce strategies have reduced this to approximately 500.
Glencore has prioritised redeployment and support initiatives, including on-site counselling, resume workshops, and job fairs.
Additionally, Glencore is assessing the future of its Mount Isa copper smelter and Townsville copper refinery amid challenging global market conditions.
“Our copper smelter and refinery are strategic assets for the state of Queensland,” Strohmayr said.
“We have approached both the Queensland and Federal Governments about the future of these assets and their support for a regional solution that benefits the whole north-west Queensland.”

Mining Input Costs Remained Unchanged At 3.8% Year-On-YearIn February 2025, the Minerals Council South Africa’s Mining Input Cost Index rose 3.8% year-on-year (y-o-y), unchanged from the y-o-y growth recorded in January. A moderate improvement in the Nominal Effective Exchange Rate (NEER) helped lower costs for imported intermediate goods, and reduced financing costs eased capital financing expenses. These gains were largely offset by higher prices for chemicals and man-made fibres, as well as an increase in mining and quarrying intermediate input costs on an annual basis in February. The chart below illustrates the trend in total mining input costs, using headline manufacturing PPI as a benchmark.
The largest cost movements over the 12 months to February were driven by financing costs, electricity, chemicals and other man-made fibres, and intermediate imports. Figure 2 below highlights these annual shifts affecting the industry.
Financing costs saw some relief. The South African Reserve Bank (SARB) reduced the repo rate by 0.75 percentage points over the past year, which lowered the prime lending rate to 11% and helped ease capital financing expenses for mining operations. Electricity costs remain the biggest concern. As we have noted before, the above-inflation increases in electricity tariffs continue to be the primary driver of annual input cost growth. Over the past two decades, the average electricity price for mining has surged from 15.07 cents per kWh in 2003 to 143.51 cents per kWh in 2023 – an 852% increase. This trend will persist, with the National Energy Regulator of South Africa (Nersa) approving a 12.74% electricity tariff hike for direct Eskom customers (effective April 1, 2025) and an 11.32% increase for municipal bulk purchases (effective July 1, 2025) for the 2026 financial year.
Chemical prices and other intermediate costs also saw notable increases. Ammonia prices – a key ingredient in explosives used for blasting and mineral extraction – rose 20–25% over the past year. Additionally, prices for polypropylene and propylene, which are used in protective mining equipment, filtration systems, piping, and certain chemical processes, also increased, adding further cost pressures to the sector.
Rubber prices have increased by a comparable margin, directly impacting tyre costs, which are a major expense in mining operations due to the extensive use of heavy-duty haul trucks and other machinery.
On the positive side, prices for coke and refined petroleum products declined 5.7% y-o-y, largely due to easing crude oil prices and an improvement in the rand’s performance. The NEER appreciated by 5.9%, reducing the cost of imported inputs.
Encouragingly, the rand strengthened against major trading partners, appreciating 0.7% from January to February, trading at R18.47 to the US dollar (from R18.72 in January). There were also gains against the euro and Japanese yen. Similarly, at the end of January, the SARB lowered the repo rate by 25 basis points (0.25 percentage points), helping to ease financing costs in February. On the downside, crude oil prices rose in January to US$78.20 per barrel, up from US$73.20 in December 2023. Due to the typical one-month lag in crude oil price adjustments filtering through to petroleum products like petrol and diesel, February saw higher coke and refined petroleum costs.
In February 2025, the gold sector recorded the highest average increase in input cost inflation. The other mining and quarrying sector, iron ore, other metallic minerals, and manganese sectors saw the next fastest rise in input costs.
The macroeconomic environment remains highly uncertain, with several factors influencing mining input costs in South Africa. One key risk is US trade policy uncertainty, particularly regarding tariffs imposed during the Trump administration. These tariffs could contribute to higher inflation and weaker growth in the US (and globally), which may delay interest rate cuts by the Federal Reserve. A slower rate-cutting cycle in the US limits the SARB’s ability to lower the repo rate, keeping borrowing costs elevated. That said, many analysts still anticipate two 25-basis-point cuts by the Federal Reserve in 2025, as policymakers cautiously assess the impact of tariffs. If these cuts materialise, the SARB may follow suit, easing capital costs for businesses, including the mining sector.
On the electricity front, the 12.74% tariff increase for Eskom customers took effect on 1st April, for the 2026 financial year. However, tariff increases for the 2027 and 2028 financial years have been set at 5.36% and 6.19%, respectively – a shift from the double-digit hikes seen in previous years. This suggests a gradual easing in electricity cost pressures for the mining sector over the medium term, although costs remain elevated.
Another key factor is crude oil price volatility, driven in part by geopolitical tensions, including US-Iran relations, the potential for increased Russian crude oil exports, tied to discussions around lifting sanctions as part of a possible peace deal with Ukraine. Fluctuating crude oil prices directly impact diesel and petrol costs, which are major expenses for mining operations.
Beyond direct input costs, US tariffs on South African-produced vehicles could have indirect consequences for mining. According to the World Platinum Investment Council, the 25% tariff on South African automotive exports could reduce platinum demand by 70,000 ounces and palladium demand by 269,000 ounces. A decline in demand for these metals could affect investment decisions, and ultimately production costs.
Overall, while we remain cautiously optimistic that cost pressures will not escalate drastically, macroeconomic and geopolitical uncertainties will likely continue to drive volatility in mining input costs.

Capital will utilise the majority of the fleet from the Sukari gold mine, with operations set to start at the beginning of Q4 2025 and full utilisation anticipated in the second half of 2026.
Capital executive chair Jamie Boyton said: “Reko Diq is set to be the next truly major copper operation in the world and so it is exciting for us to be bringing our services to the site at the very beginning of its development, first through drilling and now adding mining services.
“Today highlights the strategy core to Capital of focusing on adding our services at long-term contracts at world class assets. We are also thrilled to be able to redeploy the majority of our mining kit from our previous two mining contracts and continue to drive a return from this investment.”
The contract expands Capital’s service offering at Reko Diq and builds on its record since 2023 and its long-standing relationship with Pakistan since 2008.
The company will continue providing reverse circulation and diamond drilling geotechnical services for the project alongside the new contract scope.
Reko Diq, co-owned by Barrick, federal state-owned enterprises and the Government of Balochistan, is expected to become one of the world’s largest and low-cost copper-gold operations.
The project is expected to rank among the top ten global copper mines by production, with a low C1 cash cost of $0.53/lb based on Barrick’s feasibility study.
Reko Diq has an estimated mine life of approximately 37 years, and additional exploration targets have been identified that may extend the mine life.
According to Barrick Gold CEO Mark Bristow, the mine is projected to generate $74bn (C$104.8bn) in free cash flow over the next 37 years.mining

How Rental Partners Improve Mining Dewatering AgilityMost mines operate permanent dewatering infrastructure to safeguard operations and safety. Yet, as mines dig deeper and wider for high-quality minerals, contend with extreme weather shifts, and manage water debris and contaminants, dewatering requirements are creeping outside the scope and budgets of established systems.
Normally, this shift would require expensive capital expenditure to expand dewatering capabilities. But rental fleets provide cost-effective and agile alternatives that complement existing dewatering infrastructure and planning.
Dewatering is inherently costly, requiring specialised equipment like high-capacity pumps, filtration systems, and pipelines, as well as ongoing operational and maintenance expenses for handling corrosive and abrasive mine water. Sites need the right pumps for their conditions, supported by key infrastructure such as the appropriate pipelines and power supplies.
These factors make it tough for mines to maintain resilient dewatering systems as market and weather conditions shift.
“Dewatering systems are sensitive to changes in site variables, requiring operators to consider several factors,” says Chetan Mistry, strategy and marketing manager at Xylem Africa. “As they go deeper underground, they need to ensure the equipment caters for water table levels, ground water flow, climate changes (particularly heavy rainfall) water quality, explosion\flame proofing and that elements like electric cables and pipe inlets don’t endanger personnel. Many mines, especially open-pit mines, dig wells to help their dewatering. These interventions require planning and design, creating unexpected costs when unexpected things happen.”
Unexpected things are happening. According to the 2019 CDP report, In Too Deep, intensified storms and flooding are already the top two drivers of negative financial impact on mining operations, collectively accounting for over a third of mining disruptions.
Reactively upgrading dewatering infrastructure is unsustainable. Instead, mines need breathing room so they can hone their dewatering plans and budgets. The smart choice is to incorporate rental dewatering fleets into their strategies.
Mines frequently use industrial equipment rentals, a market valued at over US$141 billion. As dewatering expands from routine services to strategic operations, mines have increased their use of rental dewatering fleets and crews.
Rental fleets provide skilled operators and modern equipment, empowering mines to develop flexible dewatering strategies without risking capital expenditure. Rental operators shoulder the responsibility of equipment maintenance and human capital development, recouping their costs through services to multiple clients.
This approach offers significant budget advantages to mines. Renting dewatering equipment delays and even eliminates weighty capital investments. Instead of tying up capital, mines can allocate resources more efficiently by renting pumps and other dewatering equipment on an as-needed basis.
Rental agreements also enable mines to scale their dewatering operations based on fluctuating needs, such as varying water levels, changing project requirements, and emergencies. Reputable rental companies minimise downtime and prevent costly damages. They offer rapid response dewatering solutions, cultivating the resources and expertise to deploy pumps and other equipment in critical dewatering situations.
The best rental fleet operators partner closely with water equipment OEMs, ensuring access to new technologies, the latest training, and optimal maintenance, says Mistry.
“Rental fleet business models can invest in new and varied technologies, ensuring they have the most efficient and suitable options for different environments. This helps their mining clients to remain flexible and plan for the long term.”
Examples include high-capacity centrifugal pumps for large volumes, submersible borehole pumps for deep wells, positive displacement pumps for handling high solids content, pontoon-mounted pumps for open water, and submersible pumps designed for confined spaces. Leading rental companies also have specialised pumps and skills to handle contaminated water and reduce environmental impacts.
Mining operations face harsher weather, changing market demands, and more variable conditions. Agile dewatering opens up space in their budgets and timetables, using rental agreements to create flexibility and scalability, as well as access to advanced technology.
“Mines can tailor rental agreements to match their needs, whether it’s for exploration, emergencies, or managing elements such as slurry dams and environmental concerns,” says Mistry. “Rental fleets enable mines to stay in charge and profitable while reducing their water-related risks.”mining

Luca Mining Begins Commercial Production At Tahuehueto Mine In MexicoCanadian mining company Luca Mining has started commercial production at its Tahuehueto gold-silver mine in Durango, Mexico.
The company has achieved a consistent throughput rate of more than 800 tonnes per day (tpd) at the project.
The gold standard of business intelligence.
Find out more
The construction of the Tahuehueto mine was completed in July 2024.
For 2025, Luca Mining anticipates producing between 85,000 and 100,000 gold equivalent ounces, with payable ounces expected to range from 65,000 to 80,000.
Luca Mining president Ramon Perez said: “This milestone marks a significant step in the mine’s development, reflecting the operational team’s dedication and the effectiveness of recent optimisation efforts.”
The company projects generating free cash flow before working capital adjustments of $30–40m.
In 2025, the company will invest $27.4m (C$39.44m) in its projects, allocating $23.5m to sustaining capital and $3.9m to exploration across its two operating mines, funded by operational cash flow.
In Tahuehueto, infrastructure enhancements including the construction of a spare parts warehouse are being prioritised to improve operational resilience.
The processing plant, with an installed capacity of 1,000tpd and production rates of up to 1,200tpd, currently operates at 82% availability, with plans to increase this to 85–90%.
In Tahuehueto, $10.5m is planned for capital expenditures, with $6.5m for mine workings and $2.6m for a 5km drilling exploration programme aimed at resource expansion and mine life extension.
Efforts are also ongoing to increase throughput to above 2,000tpd by the end of 2025 at the company’s other mine, Campo Morado, with a focus on improving metal recoveries and grade consistency.
Campo Morado is an underground operation in Guerrero State, producing copper-zinc-lead concentrates with precious metals credits.
The development of a third copper concentrate is expected to improve the payability of precious metals.
A minimum 5km exploration programme is planned to expand mineral resources and continue production for the long term.
At Campo Morado, $13m is allocated to capital projects, including $10m for the development of mine workings. A 5km, $1.3m drilling exploration programme is set to increase high-grade resources and evaluate regional targets.mining

Denarius Metals Commences Mining At Zancudo Project In ColombiaCanadian junior exploration company Denarius Metals has officially started mining activities at its Zancudo gold-silver project in Colombia.
The first production from the project is anticipated in the second quarter of 2025 (Q2 2025).
The gold standard of business intelligence.
Find out more
This milestone reflects the company’s efforts throughout 2024 to advance the project’s development and construction, secure the necessary mining licence and gain approval for the environmental impact study (EIS).
In 2024, it prioritised the Zancudo and Aguablanca projects in Spain, with both expected to start operations within the next 12 months, thus providing internal cash flow.
The company also announced that the European Commission has recognised Aguablanca as a strategic project.
Denarius Metals has secured the long-term economics of its projects by signing offtake contracts with global companies for 100% of concentrate production.
An eight-year contract with Trafigura for Zancudo’s gold-silver concentrate and an agreement with Boliden Commercial for Aguablanca’s nickel-copper concentrate were signed in 2024.
Additionally, a prepayment agreement with Trafigura in February 2025 provided $2.5m (C3.6m) upfront, with up to $6.5m more expected as construction milestones are reached at the Zancudo project.
The Zancudo project’s development plan, executed by the company’s mine contractor, aims to open four primary fronts within the next four to six months.
Concurrently, early production activities have commenced, with mining already under way in accessible areas.
The contractor is stockpiling ore on-site, with deliveries to Trafigura under an offtake contract set to begin by the end of April.
All processing plant equipment has arrived and is stored at the site, with earthworks starting soon and installation of the plant scheduled over the summer. The plant is set to commence operations by Q4 2025.
To mitigate the impact of permitting and licensing delays experienced in 2024, Denarius Metals improved its financial liquidity by amending the terms of its convertible debentures and selling a 29% equity interest in Rio Narcea Recursos (RNR), Aguablanca project’s owner, back to the RNR Shareholder Group, retaining a 21% fully paid equity interest.
In December 2023, Denarius Metals signed a definitive agreement to acquire a 50% stake in RNR for a cash consideration of €25m ($27m).mining

Duketon Mining Granted New Gold-Prospective Tenement At Barlee Project In AustraliaDuketon Mining has been granted a new tenement, E77/3160, at its 100%-owned Barlee Project in Western Australia’s (WA) Southern Cross region.
This tenement is considered prospective for gold, base metals and lithium, further expanding Duketon’s portfolio in the area.
The Barlee Project is located approximately 200km north of Southern Cross in a region with several small gold deposits including the Mt Dimer and Marda Gold projects, and the Penny Mine.
The newly acquired land adjoins the company’s existing holdings, increasing the total granted tenure at the project to 253km² and extending the project by 38km along the Youanmi and Clampton faults.
The Barlee tenement covers the granite-greenstone contact, primarily overlying the Archean Diemals Formation, known for its siltstones, shales and mudstone.
This area is part of a fault-bounded basin with mineralisation observed in the south at gold prospects such as Bronzewing, Yarbu and Andromeda.
The project’s southern tenements, contiguous with the company’s existing holdings, have defined gold targets from broad spacing auger sampling, which are yet to be drilled.
Prior exploration on E77/3160 includes regional auger soil sampling, with 306 samples collected and analysed, revealing a maximum gold concentration of 92.7 parts per billion (ppb) and several anomalies over 30ppb gold.
Ultra-fine fraction (UFF) soil geochemistry has identified two significant gold anomalies on the tenement.
In the north, a 3.8km by 1.8km anomaly lies near the Clampton Fault, while in the south, a 3.2km by 2.2km anomaly is associated with the Diemals Formation.
Additionally, six rock chip samples were collected as part of a lithium-focused reconnaissance programme, although no significant assays resulted from this non-targeted sampling. In August 2023, Rox Resources secured binding commitments for a placement of A$7m ($4.5m) to support development programmes at its Youanmi gold project in WA.mining

1.1-Billion-Tonne Phosphate Resource Gets Nt BackingThe Northern Territory Government has granted two mineral leases to Verdant Minerals, a privately-owned fertiliser minerals explorer focusing on phosphate and sulfate of potash.
The two mineral leases concern Verdant’s Ammaroo phosphate project in the NT, which has an estimated mine life of at least 25 years and an estimated capital expenditure of $700 million.
Acting NT Chief Minister and Mining and Energy Minister Gerard Maley said the leases are a critical step towards bringing a promising mining development closer to production in central Australia.
“This is a significant milestone in progressing a world-class resource project that will support jobs, drive investment, and strengthen the NT’s position as a leader in resource development,” Maley said.
“The Ammaroo project will support 400 jobs in construction and another 250 jobs once in production, delivering real benefits for local communities and businesses, and help deliver on our promise to rebuild the economy.”
Ammaroo has an independent JORC resource of 1.141 billion tonnes of phosphorus pentoxide at an average grade of 14 per cent, making it the largest JORC compliant phosphate resource in Australia and one of the largest undeveloped phosphate resources globally.
Building off this significance, Verdant is now in the final stages of securing its mining authorisation, which will allow construction and other site works to commence at the site.
“With the project now consented to by Native Title Holders and the NT Government granting tenure, Verdant now has crucial certainty to progress the project financing process,” Verdant managing director Chris Tziolis said.
“We thank the NT Government for their continued support of the project, and we welcome steps taken by the new government to progress projects like ours.”
Considered one of the NT’s 17 critical minerals, phosphate is a critical component in many fertilisers.

Metalsgrove Mining Acquires Three Gold Permits In Côte D’IvoireAustralian miner MetalsGrove Mining has signed a binding term sheet with Australian Securities Exchange (ASX)-listed Desert Metals and its subsidiaries to acquire three gold joint venture (JV) permits in Côte d’Ivoire, West Africa.
The acquired permits encompassing the Vavoua, Vavoua West and Kounahiri West projects, collectively known as the Central West Gold Joint Venture (JV), are currently held by Générale des Mines et Carrières (GEMICA), a privately owned company in Côte d’Ivoire.
Desert Metals holds the right to earn a majority interest in each of the permits under existing JV arrangements.
Under the terms of the deal, Desert Metals will transfer its JV rights to MetalsGrove in exchange for a structured consideration.
This includes an initial A$50,000 ($31,426.3) cash payment upon the grant of the Vavoua licence, followed by another A$50,000 upon the grant of either the Vavoua West or Kounahiri West licence, whichever is first.
Additionally, a milestone-based payment of A$1m will be made upon the estimation of a JORC-compliant mineral resource exceeding 500,000oz of gold (or gold equivalent) with a grade above one gram per tonne, with a maximum payout of A$3m.
Lastly, Desert Metals will receive a 1% net smelter royalty on production from the projects, capped at either A$3m or the royalty amount from the first 125,000oz of gold production, whichever is greater.
This strategic move will enable Desert Metals to focus on its principal Adzope and Tengrela South gold projects.
Desert Metals managing director Stephen Ross said: “Throughout our exploration programmes in Côte d’Ivoire since 2023, we have strategically concentrated our resources and expertise on our two flagship projects: the highly prospective Adzope gold project in the southern region and the advanced Tengrela South gold project in the north.
“While the GEMICA joint venture projects demonstrate significant potential for gold mineralisation, particularly given their location along the same structural corridor as the producing Abujar gold mine, we had earmarked them for future greenfields exploration pending the grant of permits as well as budget allocation.”
The three permits span approximately 950km² and are strategically positioned between 60km and 140km north-east of the operational 3.8-million-ounces Abujar gold mine.
These greenfield projects are pending formal approval and have not yet undergone modern mineral exploration.
The Vavoua permit is due to be officially granted soon following approval by the Interministerial Committee.
MetalsGrove Mining managing director and CEO Lijun Yang said: “This strategic acquisition allows us to leverage our extensive gold exploration expertise within this prolific geological setting.
“With a favourable geological framework, highly anomalous gold results from neighbouring projects and structural insights derived from aeromagnetic surveys, we are confident in the potential to identify significant gold deposits.
“Our initial exploration programme will commence promptly upon the successful completion of the transaction and once permits are granted.”
In December 2023, Desert Metals agreed to acquire Côte d’Ivoire-based CDI Resources.mining
