MLG Oz’s integrated operating model to be tested at Gold Fields sites

Gold Fields has formally awarded the provision of site services and haulage at its Granny Smith underground gold mine, and open-pit mining services at St Ives for the Swiftsure deposit, to MLG, the mining services provider says.

The letter of award from Gold Fields is subject to both parties reaching agreement on formal terms.

Along with these new opportunities, MLG has also successfully extended its contractual arrangements to support Gold Fields’ Agnew site in a planned cut back of its Barren Lands open pit.

The Granny Smith contract is for a three-year term with an option to extend for another two years, with the contract expected to contribute some A$9 million ($5.9 million) in additional revenue in MLG’s 2024 financial year.

The Swiftsure open-pit mining services at St Ives comes with projected revenue of circa-A$20 million, with the project comprising a single open-pit gold mine incorporating load and haul services. The initial project is expected to be completed in eight months, starting in January.

The planned cut-back of the Barren Lands open pit at Agnew involves supplying the necessary mining equipment to execute drill and blast and load and haul activities, with the works having commenced in November 2023 and expected to continue through to March 2024.

MLG founder, Managing Director and majority shareholder, Murray Leahy, said: “We are delighted to expand our integrated services model across Gold Fields’ portfolio and to bring our site services expertise to their Granny Smith operations. MLG can now provide a consistent approach across all of Gold Fields’ Australian mine sites. In addition, the award of the open-pit mining scope of works at the Swiftsure deposit at St Ives, and the extension of works at the Barren Lands open pit operation at Agnew, acknowledges the breadth of service and overall capabilities across MLG’s integrated operating model.”

Dyno Nobel, Fortescue sign tech alliance focused on drill and blast decarbonisation

Incitec Pivot Limited’s Dyno Nobel is to extend its supply relationship with Fortescue, with the two parties agreeing to a long-term extension that will see Dyno Nobel continue providing explosives technology and collaborating on key decarbonisation projects to assist Fortescue in reaching its ‘Real Zero’ goal.

A key focus of the new agreement is an innovative technology alliance. As part of this, Dyno Nobel will invest A$5 million ($3.2 million) in new technologies to support Fortescue’s decarbonisation efforts within its drill and blast process. The new agreement will apply across Fortescue’s Pilbara operations: Cloudbreak, Christmas Creek, Solomon and Eliwana. The Iron Bridge project, which Fortescue has a majority stake in, is supplied by Dyno Nobel under a separate contract the two companies announced last year.

Dyno Nobel Asia Pacific President, Greg Hayne, said: “We’re incredibly proud of our relationship with Fortescue who are at the forefront of efforts to decarbonise the mining industry. The agreement will see us ramp up our decarbonisation efforts which will include conversion of our MPU (mobile processing unit) fleet to renewable energy sources and investigating the use of lower carbon footprint, bio-fuel based explosives.

“This is about providing our customers with technology solutions that lower our carbon footprint and, in turn, theirs.”

Fortescue Metals CEO, Dino Otranto, said: “We’re looking forward to continuing our successful partnership with Dyno Nobel, which will deliver blasting services as well as provide new technologies to help us achieve our industry leading target of Real Zero emissions across our Australian iron ore operations.”

The agreement will provide Fortescue with the opportunity to benefit from Dyno Nobel’s commercialisation of a reduced GHG emissions DIFFERENTIAL ENERGY® solution, an explosives method that tailors the energy delivered to different rock layers within a blast hole and across a blast. The efficiencies generated through the use of DIFFERENTIAL ENERGY reduce both overall mining costs and emission volumes for customers, according to Dyno Nobel, with the reduced emissions solution able to reduce Scope 1 emissions by up to 25% in normal blasting circumstances.

Hayne said that since Dyno Nobel’s DIFFERENTIAL ENERGY technology was introduced to the Australian market in 2018 it has provided customers with production and environmental benefits.

“Fortescue has already seen the technology deliver value at their Iron Bridge operations, one of the first sites in Australia to fully benefit from DIFFERENTIAL ENERGY and the results have been very positive. We are now pleased to be increasing these advantages via a reduced emissions offering. It is just another example of our technology innovation happening on the ground.”

He said Dyno Nobel’s technology development aligned with Fortescue’s vision.

“We are looking forward to continuing our successful partnership with Fortescue which has evolved into finding innovative and sustainable solutions for the future by working together,” he said.

Aquirian set to expand drill and blast portfolio with Hanwha ammonium nitrate emulsion plant

Specialist mining services provider Aquirian Limited, via its wholly owned subsidiaries, has entered into a binding agreement to acquire the assets and land comprising the Wubin ammonium nitrate emulsion plant from Hanwha, with the company also setting out plans to offer Hanwha’s patented X-Load™ range of products in Western Australia.

The facility was built and commissioned in 2020 and is production-ready, with licensing to produce 110,000 t/y of ammonium nitrate emulsion. It was put into care and maintenance in 2021 as part of Hanwha’s strategic decision to exit the bulk explosives market in Australia, with Hanwha selling its other emulsion production assets in Queensland and New South Wales to Orica earlier this year.

Aquirian will pay A$9.6 million ($6.04 million) for the facility, which is some way below the replacement cost of A$18 million the company previously obtained.

The facility site comprises 142 ha of freehold land in Wubin, with the company having also purchased an adjoining property of 9 ha in September this year. This additional property provides accommodation options for staff, with airstrip access, and is expected to de-risk the investment in the facility by allowing for future growth in capacity and storage.

The Wubin facility is strategically located on the northern freight corridor, removing exposure to major population centres and providing access to up to 1.25 Mt of potential explosive demand across Western Australia, the company estimates. The facility’s location provides direct access to up to 75% of the potential explosives market across the Midwest and Pilbara, it says.

Aquirian Managing Director, David Kelly, comments: “This unique opportunity evolves Aquirian as a diversified mining service company, adding further value across the drill and blast value chain. Our management team has extensive industry knowledge, including with this facility, and I am excited by this acquisition and the potential synergies and opportunities it offers. Our acquisition of a near new strategically located asset below likely replacement cost is anticipated to enable us to fast-track our growth plans and provide clients with a new range of services and products to achieve sustainable outcomes in their operations.”

Kelly was also previously the Managing Director of Hanwha in Australia.

The transfer or securing of required licences in favour of Western Energetics is anticipated to take 3-5 months and is a condition precedent to completion of the sale transaction. Once the sale transaction is completed, it is expected to take between 8-12 weeks to bring the facility back online and into production, the company says.

The facility can produce a variety of nitrate-based emulsions. These emulsions are a class 5.1 dangerous good used as a precursor raw material that is blended with other materials to produce a variety of bulk explosives, which are used in mining operations across Western Australia.

The site is also set up as a logistics and storage hub for ammonium nitrate with a storage capacity of 1,500 t currently, with the objective to be expanded to circa-10,000 t.

Aquirian’s technology portfolio is focused on optimising blast hole quality to ensure better client outcomes. This acquisition will bring the company’s offerings closer to providing drilling technology alongside optimised energetics, to meet its clients’ changing and challenging mine conditions, it says.

The acquisition of the facility is conditional on Hanwha granting the company an exclusive licence to manufacture and supply Hanwha’s patented X-Load range of products in Western Australia and a non-exclusive licence to use and sell other of Hanwha’s products. X-Load is a low-density waterproof energetics solution for the challenging and wet mining conditions in the Pilbara mining region. This region traditionally uses basic ANFO product which is not waterproofed. X-Load provides an energy profile and density that mimics ANFO while being a waterproof solution, according to Acquirian.

Nyamal Holdings to help Fortescue with drill and blast program at Iron Bridge

Fortescue has signed what it says is a major agreement with the Nyamal traditional custodians to provide mining equipment for the company’s Iron Bridge magnetite project, in Western Australia.

The A$18 million ($12.1 million) agreement, which builds on the A$331 million in contracts already awarded to Nyamal businesses since 2019, will see Nyamal Holdings initially provide five contour drill rigs, one stemming loader and two platform rigs to Fortescue. This will grow to include six additional platform rigs over the next two years to meet the Iron Bridge mine plan.

Fortescue Metals Chief Executive Officer, Fiona Hick, said: “The drill and blast program at Iron Bridge represents one of the most crucial aspects to achieving maximum throughput in the processing plant. We are pleased that we have been able to partner with Nyamal to deliver this important capability.

“From the outset, Fortescue has been focused on practical initiatives that drive economic and employment opportunities for Indigenous Australians. Contracts like this support the growth of Indigenous businesses, enabling them to build capability which in turn provides ongoing economic benefits to communities.”

Nyamal Aboriginal Corporation Chair, Gavin Mitchell, said: “Nyamal Holdings are excited to secure this significant contract for the Nyamal people enabling us to own the fleet which will provide ongoing training and employment opportunities for Nyamal members.

“Nyamal Aboriginal Corporation have strong and ongoing engagement with Fortescue, and we are pleased that through this contract we are able to build on this longstanding relationship.”

The Iron Bridge magnetite project is an unincorporated joint venture between FMG Magnetite Pty Ltd (69%) and Formosa Steel IB Pty Ltd (31%). The joint venture partners are each responsible for their equity share of the total capital expenditure.

Fortescue reported production of the first wet concentrate at the Iron Bridge project back in April.

Iron Bridge is set to deliver 22 Mt/y of high grade 67% Fe magnetite concentrate, with the total project capital estimated at $3.9 billion, with Fortescue’s share approximately $3 billion.

GroundProbe and Orica collaborate on ‘world-first’ BlastVision solution

GroundProbe, a member of the Orica Group, has launched BlastVision®, a world-first solution that, it says, delivers actionable blast performance insights for optimal safety and productivity.

The crucial data aids in the detection of potential misfires and out-of-sequence firing and in identifying and tracking fly rock, according to the company. Intra-blast monitoring also adds valuable wall control insights, such as monitoring and mapping instantaneous blast damage to slopes and identifying movement on significant structures.

GroundProbe, a specialist in geotechnical monitoring, leveraged the partnership with Orica, a leading mining and blasting solutions provider, to gain information around current blast monitoring methods through interviews with engineers, according to GroundProbe CEO, David Noon.

“Through talking to mine site engineers responsible for blasting on the ground, we identified that many sites were still using quite simple and sometimes unsafe methods for blast analysis.

“Techniques included recording blasts with ground-based camera systems and conducting visual inspections of this footage to determine areas of concern.

“From this, the idea of using drone footage and automated algorithms to quickly identify key areas of interest was born.”

BlastVision takes custom high-speed drone footage of a blast as it happens, using world-first advanced proprietary algorithms and modern AI frameworks to convert the footage into analytics data, according to GroundProbe. Data is then remotely analysed in its custom software platform, with insights swiftly reported back to the site. From these insights, mine site personnel can optimise blasting and monitor the impacts of blasting, improving both safety and productivity, the company said.

The solution has been tested, trialled or demonstrated across over 60 mine sites around the globe, positively impacting hundreds of drill and blast team members across these mine sites, according to GroundProbe.

GroundProbe’s VP – Technology, Fernanda Carrea, said that no other solution provides the range of insights from the whole blast area that BlastVision provides, from start to finish.

“BlastVision provides an increased level of safety, efficiency, accuracy and productivity through our software algorithm automatically identifying key areas and issues,” Carrea said.

“Data is also able to be captured before, during and after a blast, and covers the blast area in its entirety.

“We can proudly say that this patent-pending technology is a world first.”

Orica ups the fragmentation monitoring ante with FRAGTrack Gantry

Orica has announced the release of what it says is its most innovative fragmentation monitoring solution yet, FRAGTrack™ Gantry.

The company calls FRAGTrack Gantry a market-first haul truck measurement solution that combines real-time oversize detection alerts and accurate particle size distribution (PSD) of fragmentation on all models and sizes of haul trucks.

The new product combines the success of the existing suite of automated post-blast fragmentation monitoring solutions – covering the original FRAGTrack release and the release of FRAGTrack Crusher earlier this year – and the feedback from customers experiencing loss of production due to crusher blockage.

FRAGTrack Gantry uses advanced machine vision and machine learning technologies to enable autonomous triggering and processing, without interfering with the haulage operation, Orica claims

It leverages real-time oversized detection through artificial intelligence (AI), with the machine-learning capability applied to real-time detection accomplished within seconds, with alerts syndicated via Fleet Management Systems (FMS), email or SMS for the re-routing of trucks. Operators can also predetermine customisable oversize limits, enabling a reduction in crusher blockage/damage frequency due to oversize material, the company says.

Orica Vice President – Digital Solutions, Raj Mathiravedu, said: “The full adoption of AI technology into our architecture, coupled with our strategic partnership with Microsoft, allows us to expedite the delivery of capabilities that were not previously possible, and FRAGTrack Gantry is another example of how we are leveraging AI to help deliver intelligence and value to our customers.”

The reliable and accurate fragmentation information from FRAGTrack Gantry enables customers to optimise their drill and blast operations for downstream processes without impacting the haul circuit operation, Orica says. The addition of a Gantry option complements the suite of FRAGTrack measurement systems currently available for shovel-, crusher- and conveyor-mounted configurations.

Sandvik introduces new tophammer drill rig for drill and blast contractors

Sandvik Mining and Rock Solutions is launching what it says is a new, even more productive and sustainable top hammer drill rig, designed especially for drilling and blasting contractors.

The redesigned Dino™ DC420Ri will replace its predecessor, the Dino DC410Ri, although the proven overall concept – namely the biggest coverage area in its class and powerful rock drill – will remain, Sandvik says. In addition, the new Dino DC420Ri will feature a wider carrier for improved stability and a Stage V engine for lower emissions, together with a drill rod carousel and one-hole automation for increased productivity.

During the span of just a few years, the Dino DC410Ri top hammer drill rig has become a popular choice for urban contractors and others such as small mine sites and quarries looking for productivity and mobility in the 51–76 mm hole size range, according to Sandvik. The boom system has the largest coverage area in this drill rig category and the powerful 14-kW RD414 rock drill enables high-capacity drilling, it says.

Upgrades were, however, needed to ensure its proven concept remains competitive for years to come, in terms of both productivity and sustainability, Sandvik said.

Several of the key features on the newly-introduced Dino DC420Ri have been completely redesigned. A Stage V diesel engine now provides regulatory compatibility for the markets where this low-emission engine standard is required and the rig carrier is wider, offering better stability – thereby improving operator safety in difficult terrain and at challenging work sites, Sandvik said. The third major upgrade is the actual drilling system, which can now be fitted with an optional three-rod carousel cassette to enable longer holes, up to a depth of 14 m. Future upgrades will add the option of one-hole automation, making full use of the potentially longer holes and improved productivity made possible by the addition of the drill steel carousel.

In addition to the most significant upgrades to the tracked carrier, drilling system and engine, the Dino DC420Ri will also feature several other smaller, but nevertheless significant, new features, Sandvik says.

Operators of the new machine will enjoy a new 7 in (178 mm) touchscreen and a control system and screens with the same look and feel as cabinless Sandvik drill rigs Commando™ DC130Ri and DC300Ri, offering a unified user experience, ease of training and other commonality benefits, the company said. The drill navigation system is updated to the TIMi version and the electric systems have been redesigned to improve overall robustness and reliability.

Over the next few years, the Dino series will be streamlined into a single Dino DC420Ri with two engine options for both Tier 3 and Stage V emission classes, Sandvik says. Until then, the Dino DC410Ri will remain on the market to bridge the offering for those customers requiring a Tier 3 engine. Future system updates will also include an open interface for transferring 3D data to third-party systems for purposes such as drill and blast planning or production control.

Sales of the new Dino DC420Ri have already commenced, with deliveries due to start late 2022, Sandvik added.

IMDEX focuses on drilling fluids, AMC BORE HOLE STABILISER release to boost productivity

IMDEX is talking up the use of drilling fluids as part of its holistic focus on improving drilling performance when out in the field.

The company’s drilling optimisation solutions combine best-in-class technologies, sensors, and motors to deliver improved performances, but, for IMDEX Drilling Optimisation General Manager, Charles Macfadyen, drilling fluids are at the start of the value chain, maximising the data delivered from the company’s technology and tools.

“Costs are always increasing, so the emphasis is on precision drilling: drilling smart metres and drilling efficiently,” Macfadyen said.

“It all relies on fluids to be able to do that. Fluids are an essential part of the drilling process with the potential to unlock hidden productivity when used effectively.”

He says while the oil and gas industry has long understood the importance of fluids and the skills of mud engineers, the understanding within the mineral exploration community has not been as widespread.

“There is a big difference in the cost of exploration drilling between oil and gas, and mineral exploration, but the science and logic will come to mining; the understanding that it’s far more than just a fluid, there’s an understanding of what equates to precision and enhanced performance that makes it special.”

Additional costs caused by higher operational standards, environmental restrictions and increased hole depths will continue – and could be the catalyst for a greater understanding of the part played by fluids, according to IMDEX.

IMDEX has around 100 drilling fluid products to cater for specific regional and global requirements, with the most recent addition being AMC BORE HOLE STABILISER™ (BHS).

BHS is a multifunctional product formulated specifically for air drilling applications, particularly drill and blast applications.

It helps prevent a wide range of down-hole problems including poor collaring, hole decay or sidewall instability, provides a degree of lubrication to the hole and will improve the lifting capacity of the air stream for cuttings transportation, according to the company.

Use of BHS in an underground mine in Western Australia resulted in an increase of up to 40% more metres drilled per day, reduced drilling consumables by up to 50%, improved load times and explosives use for explosive crews, and reduced HSE risks through less manual handling to mobilise and install casing, IMDEX says.

“For drill and blast, the side wall imperative is for both function and efficiency,” Macfadyen said. “BHS delivers improved productivity while using less explosives and less redrills.

“IMDEX drilling fluids are much more than a fluid – you actually get the knowledge that comes not just from making premium fluids and understanding that over more than 30 years, but also the knowledge that comes from our understanding of the drilling market, and of rock knowledge.

“Others don’t have that rock knowledge. It’s the tangible knowledge that at any given moment in time you know what you’re drilling through, the geological understanding, the resource definition, the granular knowledge behind how to optimise your fluids program to cater for that.

“Whether it’s orientation, mineralogy or any geological understanding it’s the essential knowledge that you need to develop a fluid or optimise a drilling program.

“It puts us in a leading position. Unlike others, IMDEX is able to leverage intimate rock knowledge, lab capabilities and global mud engineers to unlock the potential of any drilling program.”

IMDEX’s presence in 70% of major mining operations globally has allowed the company to foster this knowledge, according to Macfayden.

Thiess to deliver mining services to Mount Holland lithium mine JV

Thiess says it has been awarded a four-year contract by Covalent Lithium to deliver mining services at the Mount Holland lithium mine in Western Australia.

Covalent Lithium is a joint venture between Wesfarmers and Sociedad Quimica y Minera de Chile (SQM), one of the world’s largest lithium miners.

Under the contract, Thiess will deliver drill and blast services, mining of overburden and ore, and equipment maintenance with a strong focus on community development and environmental protection, it said. Thiess commenced mobilisation and early mining operations in January.

Thiess Executive Chairman and CEO, Michael Wright, said: “We are very pleased to be selected by Covalent to undertake mining at the Mount Holland mine. This award recognises our team’s ability to deliver sustainable mining solutions and deliver enduring value for our clients across diverse commodities.

“We look forward to working with Covalent Lithium to safely position their operations for optimal efficiency, productivity and cost performance, and contribute strongly to a clean energy future.”

The Mount Holland Mine produces lithium-bearing ore that is concentrated and refined to produce lithium hydroxide, a mineral used to enable electric vehicles and battery-based energy storage systems. EPC contractor, Primero, is currently constructing the Mt Holland concentrator to process ‘run of mine’ ore at a rate of circa-2 Mt/y and produce an output of circa-400,000 t/y of spodumene concentrate to feed the company’s integrated lithium hydroxide conversion refinery situated in Kwinana.

Metarock Group transformation takes shape with new coal contracts

Australia-listed Metarock Group has banked two contract wins this week, one at the Cook Colliery in Queensland and one at the Maxwell underground coal project in New South Wales.

The former has seen its Mastermyne subsidiary become the contract operator at Cook for Constellation Mining, a subsidiary of QCoal Group. The contract term of four years comes with a further two-year option and the company will see work commence immediately under the Mining Services Agreement.

The Cook Colliery was purchased by QCoal in July 2020 and has been maintained under care and maintenance since the acquisition. In July 2021, Mastermyne was selected to carry out a package of work to prepare the mine to re-commence production. This work included recommissioning of existing underground infrastructure, overhauling of mining equipment, establishment of production panels and other associated administrative and procurement works. This first tranche of work has been completed and the mine is now ready to commence production.

Mobilisation underground is already well progressed with the first Joy (Komatsu) miner underground and cutting coal as it forms up the production panels that will see the next Joy machines start production mining using a low-risk place changing methodology, Metarock said.

The project will produce approximately 4 Mt of run of mine coal over four years across three production panels.

At Maxwell underground, Metarock’s PYBAR Mining Services has been named the preferred contractor for the Maxwell Underground Project Access Drifts as part of an executed letter of intent with Malabar Resources. The contract term of 12 months will commence later this year following the execution of a binding Alliance-style mining services pact.

The scope consists of twin parallel drifts around 1.3 km in length, which will provide access to the targeted coal seams. Excavation of the drifts will be carried out with metalliferous-style drill and blast equipment and methods, modified for operating within a coal mining lease.

Having only recently completed the acquisition of PYBAR and the renaming of Mastermyne to Metarock, MD Tony Caruso said: “Mastermyne’s transformation from an underground coal contractor to a diversified mining services provider is taking shape and the awarding of this project (Maxwell) is a major vote of confidence from customers in the new larger business.”

He added: “This project is quite unique in that it brings together the combination of the Mastermyne and PYBAR skill-sets, which is a real differentiator for the Metarock Group.”
