Capital, a leading mining services company, has announced the award of a material drilling contract in Nevada with Nevada Gold Mines and associated rig purchases, together with an update on the ramp up of operations at its Ivindo iron ore contract in Gabon.

The three-year drilling services contract with Nevada Gold Mines (NGM) in the US spans a wide range of drilling services including diamond, both surface and underground, and underground reverse circulation. Drilling spans a number of operations across NGM including underground diamond drilling in the Leeville underground mine within the Carlin complex, underground RC drilling in Carlin and diamond drilling at the Robertson project within the Cortez complex.

NGM is a joint venture between Barrick (61.5% ownership) and Newmont (38.5% ownership), with Barrick as operator. NGM operates three Tier One gold assets: Carlin, Cortez and Turquoise Ridge, consisting of 10 underground mines, 12 open-pit mines and associated facilities.

The contract will consist of nine rigs and will include equipment with advancements in automation for improved safety and efficiency, Capital said.

The contract is expected to generate annualised run rate revenues of circa-$35 million once all the rigs are fully operational from 2025, at margins commensurate with the broader group, Capital said. The company will purchase new rigs with associated equipment for the contract with capital expenditure expected to be circa-$20 million, predominantly falling in 2024.

In Gabon, the company reported that ramp up of operations at its load & haul, crushing and drilling contract with Ivindo Iron SA, majority-owned by Fortescue, was proceeding well.

“We have now commenced drilling operations to assist in further defining this world-class deposit,” Capital said. “The majority of the mining equipment is now in country with operations also already underway, and crushing due to commence later in the year.”

Peter Stokes, Chief Executive Officer of Capital, said: “This new drilling contract award represents a landmark moment for Capital as we extend our geographic reach in drilling into North America, adding to our existing and growing operations in Canada with MSALABS. It is a strong endorsement of our long-standing commitment to world leading standards in both safety and productivity.

“We are pleased to further expand our services with Barrick, having begun our relationship across operations in Africa before extending more globally, first at the Reko Diq mine in Pakistan, earlier this year, and now to the Nevada Gold mines complex in the United States.

“It is also great to see a continuation of our decisive and strategic move to reposition and improve our contract portfolio, set out in the second half of 2022, focusing on large-scale mine sites and Tier-1 projects with significant growth potential. The addition of world-class contracts in 2023 across Reko Diq, Ivindo and now Nevada presents significant further opportunity and a strong platform as we look into 2024.”

Based near Port Shepstone on the KwaZulu-Natal south coast, Brauteseth Blasting’s success has evolved into a national footprint – and beyond – with multiple drill rig acquisitions from Sandvik Mining and Rock Solutions bolstering its production capacity across South Africa and multiple industries, including mining.

In fact, remarks Sandvik Mining and Rock Solutions Account Manager Andre Blom, Brauteseth Blasting has acquired units from every Sandvik boom drill range in a single year.

“This included Leopard™ DI550 and Leopard DI650 down-the-hole (DTH) drill rigs from our Leopard range, the Pantera™ DP1500i and the Ranger™ DX800 and Ranger DX900i surface top hammer drill rigs,” Blom says. The two companies have built a strong partnership since 2005, when the first Sandvik rig was acquired by Brauteseth Blasting.

Brauteseth Blasting began mainly in the civil engineering sector and in quarrying, but has now moved decisively into surface mining as well. Clive Brauteseth, Managing Director since 1989, points to the geographic expansion now beyond KwaZulu-Natal and the Eastern Cape – into Limpopo, Mpumalanga, the Northern Cape and beyond South Africa into Zambia.

By this year, the number of Sandvik drill rigs acquired by the company over the years has reached almost 50, and more acquisitions are in the pipeline by the end of the year, Brauteseth says.

“We have built a strong relationship with Sandvik over my 35 years with the company,” he says. “We have some of the best equipment in the market, and keep it well maintained and up to date; this means continual investment in replacing plant regularly.”

He notes that the quality and performance of Sandvik drill rigs gives Brauteseth Blasting the uptime and reliability that its projects demand, backed up by the experience and skills of its stable and committed teams. The ongoing upskilling also ensures the latest technology investments are put to the most productive use in the field – to deliver the bottom-line results that keep customers loyal, it says.

Of Brauteseth Blasting’s acquisitions during 2021 into 2022, the Leopard range is designed for high capacity production drilling in medium-sized to large open-pit mining operations, while the Ranger DX800 and Ranger DX900i drill rigs serve mainly the construction and small mining sectors. In between, the Pantera DP1500i rig is a ‘cross over’ for applications in quarries and smaller open-pit mines.

With the experience of almost two decades of running Sandvik drills, Brauteseth believes Sandvik Mining and Rock Solutions has the edge in this market. This is important for the way that his company embraces new technology to help keep it a step ahead.

“When there is new equipment in the market, we are always interested in what it can do for our fleet capability and our customers,” Brauteseth says. “I really value Sandvik’s continuous innovation, and the way they listen to customers when pursuing those developments.”

Blom highlights the unique partnership between the companies, where Sandvik Mining and Rock Solutions provides solid OEM support to enable Brauteseth Blasting to remain self-sufficient operationally and technically. More drill rig acquisitions are in the pipeline for 2023, as the company’s growth trend only gathers strength.

Boliden has selected Sandvik Mining and Rock Solutions to supply two Leopard™ DI650i down-the-hole (DTH) drill rigs and AutoMine® Surface Drilling systems, enabling fully autonomous surface drilling at its Kevitsa multi-metal mine in northern Finland, the OEM says.

The order also includes a five-year parts and services agreement and My Sandvik Onsite analytics for process optimisation. Delivery of the two Leopard DI650i drill rigs is scheduled during the September quarter.

“Boliden Kevitsa is committed to improving sustainability, productivity and safety by investing in the latest automated technologies,” Christian Bjorne, Vice President Sales Area Northern Europe at Sandvik Mining and Rock Solutions, said. “We look forward to continuing our technology cooperation and supporting Kevitsa in its journey to becoming an even more safe and productive mine through our drilling solutions.”

The Kevitsa open-pit mine represents one of the largest mines in Finland when it comes to excavation volume. Temperatures at the mine can drop below -30°C during the winter, and, with operations running 24/7, Kevitsa requires robust, proven technology. Sandvik and Boliden conducted comprehensive field tests over several months to prove the automated Sandvik drilling technology and performance. Technical support exceeded the mine’s expectations during the field tests, according to Sandvik.

Kevitsa will run the two Leopard DI650i DTH rigs using the AutoMine system from a remote control station near the drilling area or from mine control room. Boliden and Sandvik have an ongoing rock tools agreement at Kevitsa, including DTH hammers, bits, pipes and rock tools services. Sandvik on-site technicians will ensure support is available 365 days a year, maximising the drill rigs’ utilisation, productivity and reliability, it says.

AutoMine Surface Drilling is an autonomous solution for a wide range of Sandvik i-series surface drill rigs, designed to improve safety, reduce costs and increase productivity. Sandvik says it enables an operator to control multiple rigs remotely from a comfortable line-of-sight location or a control room – improving working conditions and safety.

Leopard DI650i drill rigs are equipped with iDrill technology, a scalable automation platform that supports fully autonomous operation and is designed to accelerate the production process. iDrill onboard automatics cover all steps of the drilling cycle from automated boom positioning, drilling and pipe handling to finishing the hole, and ensures consistent high-quality drilled holes, according to the OEM. These capabilities can be upgraded with more advanced modules such as single-rig or fleet remote control systems with AutoMine Surface Drilling.

Sandvik Mining and Rock Solutions is introducing the new Sandvik RR340 single seal roller bearing rotary drill bit in an effort to, it says, boost service life and lower drilling costs.

Sandvik’s rotary bit offering has consisted of the standard air bearing bit Sandvik RR240 and the ultra-premium Charger™ RR440 and RR450 bits. The Sandvik RR340, a premium single seal roller bearing bit, now completes the company’s rotary offering. Its single seal roller bearing technology and optional PowerCarbide® inserts ensure reliable and efficient drilling with 45% longer service life compared with standard products, the company says. More bearing hours mean fewer bit changes and an added sustainability benefit, with reduced risk exposure and environmental impact from production and shipping, it added.

“[The] Sandvik RR340 rounds out our offering within rotary bits, ensuring that customers in all segments and applications can find the ideal choice for their operation,” Sandra Arman, Product Manager Rotary Bits at Sandvik Mining and Rock Solutions’ Rock Tools Division, said. “Field tests have demonstrated significant cost savings potential. Compared to equivalent standard air bearing bits, a typical surface mine drilling 1.5 million meters per year could expect to save more than $800,000 annually with Sandvik RR340. This is truly the single seal effect.”

Some of the technology that provides the Sandvik RR340 single seal bit with its longevity includes an abrasion-resistant radial seal. Its shape delivers extended bearing hours and greater reliability compared with conventional seals, according to the company. In addition, the Sandvik RR340 features a low friction bearing, which minimises friction and heat generation, which can otherwise cause wear and reduce efficiency.

“There is significant research and development that lies beneath the surface of Sandvik RR340, with several cutting-edge design and material innovations,” Arman said.

The Sandvik RR340 is currently available in sizes ranging from 6.75 in (171 mm) to 12.25 in (311 mm).

Macmahon Holdings says it has extended its appointment by PT Agincourt Resources (PTAR) as the mining contractor for the Martabe gold project in North Sumatra, Indonesia.

Macmahon has been working to support PTAR at the Martabe mine site since 2016 and, in that time, its workforce on site has grown to over 600. The scope for Macmahon on the next stage of development will involve open-cut mining activities including drilling, loading, hauling and mine site development.

The contract extension commences on April 1, 2023, for a seven-year period with the option to extend for a further two years. It is expected to generate revenue of A$350 million ($234 million) in the first seven years, adding to Macmahon’s secured order book.

Macmahon will continue to integrate safety, environmental and social considerations into its operations at Martabe and looks forward to continuing this work in partnership with PTAR and
the local communities on all these areas, it said.

The contract value of the successful extension at Martabe and other recent contract awards in financial year 2023 total approximately A$2.5 billion, which exceeds Macmahon’s financial year 2023 order book run-off. As a result, the company is better positioned to strategically pursue low-capital intensity opportunities.

Macmahon CEO and Managing Director, Michael Finnegan, said: “We are delighted to be re-appointed by PTAR as the mining contractor for its Martabe gold project and believe this reflects the significant efficiencies delivered on the project. Since 2016 we have built, and continue to build, a strong relationship with the PTAR team and look forward to being part of the further successful development of the mine. I would like to thank our Macmahon team at the Martabe project in Indonesia. Their continued dedication and support are what makes this project successful.”

Sandvik looks to transform drill bit recycling with new ‘opt-out’ program

Energy minerals, Environmental, Mining consumables, Mining services, Sustainable mining, , , , , , ,

Sandvik is introducing what it believes is an industry-first ‘opt-out’ recycling program for customers of carbide drill bits, aiming to transform the use of a material expected to run out within 40 to 100 years if consumption rates continue unabated.

Tungsten, a key component in cemented carbide, is a scarce and finite material. Making tools from recycled carbide requires 70% less energy and emits 64% less CO2. It also reduces nitrous oxide emissions, according to the OEM.

Sandvik aims to collect 90% of its own used bits by 2025, while other manufacturers’ used bits can also be recycled within the scope of the new initiative.

Jens Holmberg, President of Sandvik Mining and Rock Solutions’ Rock Tools division, said: “Our breakthrough opt-out program supports our customers’ drive to mine more sustainably and demonstrates our commitment to delivering on Sandvik’s ambitious sustainability goals to halve CO2 emissions by 2030. We are determined to lead the industry into a new era, fully committed to embed circularity across an essential component of mining.”

The recycling of drill bits is an important part of making the mining industry more sustainable, yet, historically, carbide recycling has faced several challenges. Collection of used products has been limited while carbide extraction has been cumbersome, inefficient and involved hazardous ways of working, Sandvik says. The zinc recycling process has not returned the same quality of carbide performance, either.

Sandvik says it is now able to help customers overcome these challenges through its new opt-out program.

“Customer response has been overwhelmingly positive,” Holmberg said. “We need to transition our industry at an unprecedented speed. Our recycling program is one of many new initiatives you will see from Sandvik’s Rock Tools division moving forward. We are an industry leading supplier in mining globally, and we need to do everything in our power to support and push the industry forward.”

To further underline the importance of cemented carbide recycling, Sandvik is offering its customers an industry-first extraction support. This will make it easier, faster and safer to recycle dull drill bits with a new patent-pending method that will reduce emissions from transportation by 93%, it says.

Epiroc achieves major open-pit autonomous drilling milestone with Pit Vipers

Epiroc says it continues to accelerate the transformation of the mining industry toward lower emissions, strengthened safety and higher productivity with its autonomous drill rigs having achieved another milestone in successfully drilling the equivalent length of more than once around the world.

The company’s drill rigs, used by mining and construction customers across the world, are increasingly operated autonomously. The company’s Pit Viper surface drill rigs have now drilled holes totalling more than 41 million metres, exceeding the world’s circumference of 40.1 million metres.

The societal benefits generated so far are significant, including a reduction in CO2e emissions of more than 100 000 t. An equivalent in effect would be to plant a new forest the size of the Swedish capital, according to Epiroc. The reduction in CO2e emissions is achieved through increased efficiency of autonomous drilling, higher-precision drilling and a significantly reduced need for travel to the rigs, which can be at a far distance from the control room.

Similarly, Epiroc’s autonomous underground rigs, such as the Simba production drill rigs, are increasingly used by customers. One of Epiroc’s mining customers has drilled more than a million metres autonomously underground using a single Simba rig.

In addition to lower emissions, other benefits of autonomous drilling include a safer and more comfortable work environment for operators, and higher productivity.

“Our autonomous drilling solutions are one example of how we are accelerating the transformation toward a more sustainable future,” Helena Hedblom, Epiroc’s President and CEO, says. “We have a rigorous innovation agenda, also within digitalisation and electrification, to find new ways to reduce the environmental impact, while increasing safety and productivity.”

Epiroc says it has launched several initiatives to support the industry to extract the needed minerals in the most sustainable and efficient way possible. For example, it is working toward offering its complete fleet of underground mining equipment in emission-free versions by 2025, and its full fleet of surface equipment in emission-free versions by 2030. Another example is the partnership with steelmaker SSAB that began in 2022 to produce mining equipment using fossil-free steel.

Epiroc also supports the transition towards a circular economy by providing equipment and services that enable the recycling and reuse of materials. For example, Epiroc’s hydraulic attachments tools are used by the construction industry to process concrete, asphalt and other materials on site, reducing waste and improving resource efficiency.

In 2021, Epiroc received validation from the Science Based Targets initiative (SBTi) for the 2030 targets to halve its CO2e emissions in own operations as well as from the use of sold products. The SBTi validated Epiroc’s climate targets as being in line with keeping global warming at a maximum 1.5°C, consistent with the latest climate science and the goal of the Paris Climate Agreement.

IMDEX has announced record first-half revenue to end-2022 matched with targeted acquisition activity designed to, it says, further enhance its market-leading position.

The company reported strong growth in Africa, South America and the Asia Pacific, and increasing demand for critical minerals as it revealed record revenue of A$198.8 million ($137.7 million), an 18.4% increase on the same time last year.

During this period, the company announced plans to acquire Norway-based Devico AS in a A$334 million ($230 million) deal that, it said, would reinforce its market-leading position in mining technology and deliver increased market penetration. This deal, the company says, is expected to be completed by the end of February. The company also signed a binding heads of agreement to acquire a 40% in Krux analytics, which delivers drilling analytics software, and an increase in its Datarock holding to 40.9%, from 30 per cent, in the period.

Revenue from the Americas in the six-month period was up 14% on the same period last year to A$89.3 million; Africa and Europe up 22% (A$48.4 million); and Australia and Asia up 22% (A$61.1 million).

IMDEX Chief Executive Officer, Paul House, said the M&A activity was a highlight of the first half of the year and the results demonstrated the strength of the company’s core business.

“We are very pleased with the performance, particularly our ability to grow the business notwithstanding the current macro-related uncertainty in our operating environment and to deliver further margin expansion on a normalised basis,” he said. “The company is well positioned to leverage the robust industry fundamentals through the unique competitive position our global presence, leading technologies and integrated solutions provide.

“Combining the IMDEX and Devico businesses is expected to further strengthen this position.

“Directional drilling, a market where Devico is the leader, is one of the fastest growing segments of the mining-tech space, as companies continue to look for deposits at depth, explore complex ore bodies and respond to the growing needs of faster, cheaper more accurate drilling services.”

Normalised EBITDA for the first half of the year of A$62.8 million, which excludes the exceptional litigation costs not expected to recur during the remainder of the financial year, was up 22% on the same time last year, and up 11% on a constant currency basis.

House said revenue from sensors and software had increased as had activity linked to the search for critical minerals.

“The global commitment towards net-zero emissions and the resultant demand for critical metals or the continued extraction of reserves is outstripping their replacement,” he said.

“Critical minerals are growing at a faster rate and IMDEX is well place to benefit from the necessary supply demand rebalance.”

Industry growth was underpinned by strong demand from mid-to-major mining companies, which reported ongoing or expanded exploration budgets for 2023, and strong financing for junior and intermediate companies in December.

Other first-half highlights included:

  • Rock knowledge sensors on rent up 6% and IMDEX HUB-IQ™ connected revenue increased by 41%;
  • Released next generation IMDEX ioGAS™ V8 data analysis software;
  • Completed first generation IMDEX MINEPORTAL™ software to support BLAST DOG™ trials and contracts;
  • Commercial prototype IMDEX BLAST DOG™trials progressing as planned; and
  • Spectra analysed with aiSIRIS™ software up 4%.
