Group 6 Metals has uncovered more ore tonnes and metric tonne units of tungsten trioxide from the Dolphin tungsten mine than originally anticipated, alongside a record month of shipments.
The company’s in-pit reconciliation methodology uses in-pit sampling, UV (ultraviolet light) lamping, and production drill hole assaying to compare mining results to the geological model.
When compared to the geological model, recoveries from the Dolphin open pit exceeded expectations up until the end of April.
Dolphin produced about 94 dry tonnes of concentrate in April at an average grade of 57.1 per cent for 5380 metric tonne units of tungsten trioxide. A total of 115.05 dry tonnes of concentrate at 57.38 per cent tungsten trioxide was shipped in April, a record month for Group 6.
“Over the past six months, our geology and mining teams have excelled at maximising ore recovery,” Group 6 managing director and chief executive officer Keith McKnight said.
“This means we’ve collected more valuable tungsten ore than forecast while working the outer areas of the Dolphin open pit. While this has caused a temporary delay in the mining sequence, the extra effort has resulted in a detailed understanding of the mine’s geology, giving us a lot of confidence in our mine forecast.
“Excitingly, the high-grade C-lens (deposit) is now accessible at -30 RL (reduced level) in the main Dolphin pit, and production drill assay results confirm the presence of high-grade ore in the mining blocks (is) scheduled for June.”
Group 6 has also made progress in sustainability. It, along with Climate Capital, has been looking into integrating a 7.5 megawatt solar panel array and a 5.5 megawatt hour battery storage system at the Dolphin mine’s power plant.
Climate Capital has finished power modelling and an extensive site assessment. If implemented, the solar power system would sit adjacent to Group 6’s process plant.
Group 6 and Climate Capital are expected to negotiate a power purchase agreement under a build own operate model to deliver the solar project.
After being closed for three decades, the Dolphin tungsten mine officially re-opened in August 2023. It is located near Grassy, a town on the south-east coast of King Island.
The International Mining and Resources Conference (IMARC) will return to Sydney from October 29–31, with a packed conference program ready to wow attendees.

A hydrogen-powered T 264 haul truck prototype developed in partnership by Fortescue and Liebherr has fired up its engines for the first time in Perth.
The successful operation of the truck, dubbed ‘Europa’, with hydrogen marks the next step in Liebherr and Fortescue’s journey to develop and supply zero-emission haul trucks for the mining industry.
“With Europa soon moving to site, Liebherr and Fortescue have taken an important step closer to their common target of developing and building zero-emission solutions for the mining industry that are both field proven and energy agnostic,” Liebherr Mining vice president of sales and marketing Joerg Lukowski said.
“This success demonstrates the incredible capabilities of two Tier 1 companies working together to develop viable technologies today that can help the mining industry move towards a decarbonised future.”
Europa contains a 1.6-megawatt battery developed in-house by Fortescue WAE, and 500 kilowatts of fuel cells. The prototype can store over 380kg of liquid hydrogen.
“Following the success of our battery electric haul truck prototype at site, we’re thrilled to now have Europa up and running on hydrogen,” Fortescue Metals chief executive officer Dino Otranto said.
“This is a huge achievement for the team and brings Fortescue another step closer to having a fleet of zero emission trucks at our sites by the end of this decade.”
Fortescue and Liebherr established a partnership for the development and supply of zero-emissions mining haul trucks in June 2022.
Liebherr began delivering the first of Fortescue’s T 264 diesel electric trucks in 2023, which will be converted to zero emission technology before the end of the decade.
“We’re aiming to transport Europa to our mining operations within the coming weeks where it will then undergo further site-based testing and commissioning,” Otranto said.
“The subsequent test results will inform our future fleet of zero emissions trucks that we’re delivering with Liebherr.”

As Tradesales celebrates Australian Made Week, the company is proud to shine a spotlight on the incredible contributions of the Australian manufacturing sector.
May 20–26 is dedicated to recognising and supporting the products made in Australia and their vital role in the country’s economy.
Australian manufacturing has a storied history and continues to be a significant economic driver, providing employment to millions, fostering innovation, and enhancing the quality of life for all Australians.
Historical context and economic contribution
Manufacturing in Australia has a rich history dating back to the 1830s, when small steam engines were produced.
The sector peaked in the 1960s, contributing 25 per cent to the country’s gross domestic product (GDP) and employing almost a third of the workforce. Over the decades, the industry has seen a decline, with its contribution to GDP dropping below 10 per cent.
By 2004–05, the manufacturing industry employed 1.1 million people and exported products worth $67.4 billion. Despite these declines, manufacturing remains a crucial part of Australia’s economy, currently contributing 6.9 per cent to GDP and supporting 862,200 positions.
Manufacturing as an economic driver
Manufacturing remains a significant economic driver in Australia, encompassing various industries such as mining equipment, pharmaceuticals, and textiles.
It provides employment for over one million Australians, directly and indirectly supporting other sectors like transportation and construction.
Supporting other sectors
The manufacturing sector boosts other parts of the economy by supplying raw materials and goods, stimulating growth in agriculture, mining, retail, construction, and healthcare. This interconnection highlights the sector’s role in underpinning the broader economic structure.
An engine of economic growth
Manufacturing is vital for the Australian economy’s growth and future prosperity. It plays a crucial role in GDP and acts as an engine of growth, fostering economic stability and expansion.
The sector’s contributions to GDP underscore its importance in maintaining and enhancing Australia’s economic performance.
Innovation and research
Australian manufacturers, such as Tradesales, are at the forefront of innovation, constantly developing new products and technologies.
This drive for innovation requires significant investment in research and development which, in turn, leads to the creation of efficient and cutting-edge products that benefit consumers and enhance daily life.
Improving everyday life
Manufacturing significantly impacts daily life, producing essential goods such as food, clothing, electronics, and vehicles. The availability of these products ensures a convenient and efficient lifestyle for Australians, underscoring the sector’s role in improving quality of life.
Economic resilience and job quality
Despite a reduction in its share of GDP and workforce, manufacturing remains a resilient sector.
It is the fourth largest sector in terms of employment, with most jobs being full-time and offering benefits like paid leave. This resilience in job quality highlights the sector’s capacity to provide stable and quality employment.
Future prospects
The future of Australian manufacturing looks promising with policies like the Future Made in Australia initiative, which focuses on transitioning to net-zero emissions and developing industries like green hydrogen and critical minerals refining.
These initiatives aim to make Australia a leader in sustainable manufacturing practices. Trends such as automation, micro-training, and a focus on sustainable energy practices are also shaping the sector’s future.
Manufacturing in Australia has undergone significant changes but remains a cornerstone of the economy. Its ability to adapt and innovate provides substantial economic benefits and quality employment.
As the sector embraces new technologies and sustainable practices, it is poised to play an even more critical role in Australia’s economic landscape.
Support Australian manufacturing
To support this vital sector, consumers are encouraged to buy Australian-made products. Research indicates that if every household spent an additional $10 per week on locally made goods, it would inject almost $5 billion into the economy annually, creating 9,000 new jobs.
The commitment to Australian-made products is strong, with 91 per cent of Australians wanting more local options and 72 per cent planning to purchase more locally produced goods in the next year.
For those looking to engage directly with Australian manufacturing, Tradesales manufactures heavy-duty storage systems, workshop equipment and relocatable site solutions for heavy industries such as mining, construction, and defence, ensuring products are made to high standards, on time, and within budget.
By supporting such businesses, individuals can contribute to the growth and sustainability of Australia’s manufacturing industry.
New report on aggregate usage revealed. Image: Enrique del Barrio/stock.adobe.com
New research from the Mineral Products Association has revealed that the usage of recycled construction aggregates has reached a record high in Britain.
The new report from the Mineral Products Association, which represents the major aggregate firms in Britain, shows that the total volume of recycled and secondary materials reached a record 73.5 million tonnes in 2022.
“The substantial contribution of recycled and secondary aggregates to total supply is a huge but largely hidden success story for the industry. Aggregates producers have been recycling suitable construction and demolition waste for years to meet our construction needs as efficiently and sustainably as possible, whilst meeting stringent technical standards,” MPA director of economic affairs Aurelie Delannoy said.
“As we look ahead, further progress in recycling can be anticipated, supported by the major investments that have recently taken place in the extractive sector. However, it is important to recognise that the availability of recycled aggregates is inherently tied to demolition activity and the availability of suitable waste materials.
“With increasing demands to achieve climate neutrality by 2050 and address key infrastructure and housing needs, primary aggregates extraction will remain essential for meeting the majority of demand over the long term.”

In the report ‘Construction Aggregates Supply in Great Britain: Primary, Recycled and Secondary Aggregates in 2022’ the MPA demonstrates that non-primary materials accounted for over 30% of the country’s total demand for aggregates (which stood at 241.8 million tonnes in 2022, the biggest flow of materials in the economy).
The data illustrates Britian has one of the highest recycling rates in the European region. The breakdown of this figure of this figure showed 60.3 million tonnes of recycled aggregates was compromised of construction, demolition and excavation wastes (CDEW) such as concrete and brick rubble, old rail track ballast and earthworks spoil. Meanwhile, 5.8 million tonnes of asphalt planings were reused in road networks in 2022.
“Whilst the construction industry may well be the country’s largest source of waste, MPA members have become proficient in recovering materials arising from build development and processing them so they can be put back to good use elsewhere in construction,” MPA’s executive director for planning and mineral resources Mark Russell said.
“The most efficient way to process and reuse these materials is close to where they are sourced to minimise transport, and the bureaucracy of the planning and permitting system is often a barrier to delivering the most efficient solutions.
“That said, there are major investments taking place to improve the quality and availability of recycled and secondary materials, giving developers and contractors the confidence to specify them. Even the small amount of soft inert waste that cannot be turned into aggregate is put to good use in quarry restoration and land remediation.”
MACA has locked in a major contract at Atlas Iron’s Miralga Creek iron ore project in the Pilbara region of Western Australia.
The mining, civil and mineral processing contractor will provide mining and drill and blast services at the mine, continuing a 15-year partnership between the companies.
The contract announcement was made by Thiess, which has owned MACA since 2022.
“This contract will see the business further embed our presence in the Pilbara’s rich iron ore industry, all while working alongside a client that has played a large role in MACA’s expansion,” Thiess Group executive chair and chief executive officer Michael Wright said.
Miralga Creek becomes MACA’s second active Atlas Iron contract, situated in close proximity to Sanjiv Ridge, a project awarded to MACA in June 2020 providing infrastructure, drill and blast, and load and haul services.
Operating at the project since mid-March under a letter of intent, MACA has since mobilised a fleet of excavators, trucks, drills and associated support equipment, as well as a 45-person workforce to ensure minimal operational downtime.
“Since 2009, we have proudly worked with Atlas Iron, consistently delivering our capability and flexibility to meet production goals.” Thiess Group executive – Australia West David Grieg said.
“Securing the Miralga Creek contract is a strong signal of MACA’s capability in delivering our promise of performance in a range of highly technical applications.
“With over 20 years’ operating in the Western Australian landscape, new contracts with both existing and former clients remain the ultimate testimonial of our performance.”

These 240 volt high flow submersible pumps are ideal for a difficult working environments where a powerful submersible pump is required. Perfect for construction sites, builders, farming and residential home owners. Move dirty water fast for any application.
Heavy Duty Submersible Centrifugal Water Pump with Float Switch
These high flow submersible water pumps are designed with a open impeller which makes them less prone to blockages and well suited for use with dirty fluids including light mud, sewage and even water containing some debris.
Paddock offer the most powerful pumps we’ve seen capable of running from a standard household 10 amp plug socket. These pumps are fitted with large heavy duty motors and are designed to move water fast.
These pumps come standard with a float switch fitted. When the float is in the upright vertical position, the internal ball drops inside the float and closes the circuit to activate the pump. When the fluid level drops, the float changes its orientation and stops the pump. The length of the float cable can be adjusted via the integrated cable clamp to custom configure the on/off trigger points if desired. Some customers not wanting the float switch have reported success in simply zip tying the float switch in the vertical ‘on’ position and this allows the pump to run continuously independent of fluid level.
Each pump includes a high quality silicon carbide mechanical seal with oil separation chamber ensuring water remains about pf the motor. This design results in long term reliable operation. Maintenance is a dream as the wet end pump can quickly be separated from the electric motor. The pump motor is constructed with 100% pure copper wire windings which helps it to run cooler and last longer for the user.
The pump is suitable for fresh, sewage or sea water*. Popular uses include water supply and disposal, home pressure pumping, irrigation, dairy, farming, fishery, residential pump, construction and building sites, sewage, grey water and flood management.
Submersible pumps rely on the fluid they’re submerged in to cool the powerful motors. Unlike non submersible pumps there is no fan to blow cooling air over a finned motor. Therefore it is important to ensure the pump is not allowed to run for extended periods of time out of the water. The included float switch is configured such that the pump will turn off before the water level drops below the motor. When installing these pumps, ensure the pit is large enough that the float switch can not become jammed in the on position as this can lead to the pump running dry eventually overheating the motor. Each motor includes thermal cutout protection as standard to save the pump from damage if it was accidentally allowed to run dry.

*Long term use in sea water may lead to corrosion which is not covered by warranty. Whilst the pump will work with sea water it is not recommended for permanent installations in corrosive salt water environments.
** Whilst the pump motor includes thermal cutout protection, this should not be used to control fluid level. Allowing the pump to run dry repeatedly only to over-heat and stop via the thermal cutout protection will significantly reduce the operating life of your pump and this type of damage is not covered under the products warranty. The pumps float switch should be used to control fluid level and this is configured such that the motor is always submersed and cool.
The PNG Expo will take place in Port Moresby this year. Image: andriano_cz/stock.adobe.com
From new mines to critical minerals, the Papua New Guinea resources sector is thriving with potential.
The 2024 PNG Industrial and Mining Resources Exhibition and Conference (PNG Expo) will be the premier event for industry professionals to discuss the latest developments in the Pacific nation.
Quarry takes a look at the top talking points.
Critical minerals
With its vast reserves of copper, cobalt, nickel and mineral sands, PNG is well-placed to help provide the critical minerals necessary for the world’s transition to net-zero.
Mayur Resources has been working to get its lime and mineral sands project up and running to help strengthen supply.
The company’s Central Lime Project is located along Papua New Guinea the coast near Port Moresby and was recently bolstered by a $9.4 million funding commitment.
“This capital injection is a vote of confidence in our ability to deliver high-value, sustainable projects,” Mayur managing director Paul Mulder said.
“It enables us to continue progressing the early development works at our Central Lime Project, setting a solid foundation for the commencement of construction.”
Mayur is aiming for the Central Lime Project to become Asia-Pacific’s first carbon-neutral cement and lime producer.
It’s this sort of innovative planning that will be on show at the PNG Expo in Port Moresby from July 3–4.
“PNG Expo will be the platform to engage and drive transformative changes towards a sustainable future,” show director Lauren Chartres said.
“Our mission is to equip the industry with the right tools.”

Education and training
The name Ok Tedi Mining (OTML) often goes hand-in-hand with education, training and apprenticeship opportunities in Papua New Guinea.
The first three months of 2024 have seen OTML deliver over $121,000 in scholarships to university students, welcome 22 new apprentices, and pledge to donate vehicles and an analytical chemistry laboratory facility at PNG University of Technology.
The scholarshipshave seen 10 third-year university students supported with full tuition and boarding for the year, as well as a book allowance and stipend, travel assistance, industrial training and an automatic offer into the two-year graduate development program upon completion of studies.
“The program aims to assist university undergraduate students with school fees and other associated costs while ensuring OTML maintains an industry-institution relationship with respective universities that provide graduates into its training programs and workforce,” OTML said.
Elsewhere in the resources sector, Kumul Petroleum’s training entity Kumul Petroleum Academy is building a new facility to expand its coaching and employment capabilities.
“We are passionate about investing in programs and projects that will upskill and develop our young Papua New Guineans so that they are ready for the projects that are coming online now,” Kumul Petroleum managing director Wapu Sonk said.
The Kumul Petroleum Academy is expected to open within two years and will have the capacity to train 350–400 trainees.
Current projects
The restart of the Porgera gold mine has been in the news a lot recently, and for good reason.
The Porgera mine, owned by Barrick Gold, is located in the Enga Province of Papua New Guinea, about 600km north-west of the capital of Port Moresby.
The Papua New Guinea Government backed the restart throughout 2023 and the mine was able to pour first gold in February 2024, with Prime Minister James Marape on hand to witness the milestone.
“Today marks a significant moment where we are witnessing New Porgera Limited’s first gold pour and stamping of the first gold bar,” Marape said at the time.
“This first gold pour is the outcome of the [Papua New Guinea] Government, New Porgera Limited, Enga Provincial Government, and mine-affected communities working together. This is teamwork.”
Enga landowners, the Enga Provincial Government and the state will receive a combined equity share of 51 per cent from Porgera. A three per cent royalty has also been included for landowners, a step up from the previous five per cent.
In the energy sector, the PNG LNG project is ramping up, with Santos selling its five per cent stake to Kumul Petroleum.
The $US19 billion liquified natural gas project is an integrated development that includes gas production and processing facilities that extend from the Hela, Southern Highlands, Western and Gulf provinces to Port Moresby in Central Province.
As Papua New Guinea’s national oil and gas company, Kumul is already an existing partner in the PNG LNG project.
These key projects, and much more, will be among the top discussion points at the 2024 PNG Expo, the safest and strongest place to network, share ideas and learn more about what companies are doing in these spaces. •
Drilling operations at the Springdale graphite project in WA. Image: International Graphite.
International Graphite has welcomed the US’ decision to impose tariffs on a range of Chinese imports, including batteries, battery components and parts, and critical minerals.
Earlier this week, the US Government announced the tariff rate on natural graphite and permanent magnets from China will increase from zero to 25 per cent in 2026, and the tariff rate for other critical minerals will increase from zero to 25 per cent in 2024.
The tariff rate on electric vehicles (EVs) will also increase from 25 per cent to 100 per cent in 2024, meaning EVs that use Chinese graphite for battery components will not be eligible for the Inflation Reduction Act (IRA) tax incentives.
The IRA legislation encourages innovation by giving firms various demand- and supply-side incentives to invest in developing and deploying clean energy technologies, while helping the country transition to net-zero.
“Despite rapid and recent progress in US onshoring, China currently controls over 80 per cent of certain segments of the EV battery supply chain, particularly upstream nodes such as critical minerals mining, processing, and refining,” the US Government said.
“Concentration of critical minerals mining and refining capacity in China leaves our supply chains vulnerable and our national security and clean energy goals at risk. In order to improve US and global resiliency in these supply chains, (the US Government) has invested across the US battery supply chain to build a sufficient domestic industrial base.”
International Graphite said graphite from its Springdale project in Western Australia will be free of US tariffs and Springdale customers will be eligible for IRA incentives as per the free trade agreement between Australia and the US.
“The timing of US tariffs coincides with the dates we expect to bring our Springdale mine into production,” International Graphite managing director and chief executive officer Andrew Worland said. “It is also the point at which world markets are expecting graphite demand to exceed supply.
“Our plan for a vertically integrated mine to market graphite business from Western Australia, fits perfectly with the goals of the US to reduce its reliance on China and secure other sources of trusted, reliable graphite.
“We have shown that Springdale has the potential to be a multi-decade, low-cost operation that will produce high quality graphite concentrates specifically for lithium-ion batteries.”
The Springdale graphite project in located in the Ravensthorpe region of WA. Since International Graphite took ownership of the project in 2022, it has grown to become one of the top 15 graphite deposits in the world.
