Trevali to test out FLSmidth’s Rapid Oxidative Leach tech on Caribou material

Trevali Mining has announced the commencement of a pilot plant testing program using Caribou run-of-mine and milled material at FLSmidth’s Rapid Oxidative Leach (ROL) process testing facility in Salt Lake City, Utah.

The program expands on previous laboratory test work and is aimed at demonstrating the potential to recover zinc, lead, copper, gold and silver as a precipitate or metal and additional zinc and lead from Caribou ore and mill tailings.

The leach test program is targeting an improvement to zinc, lead, copper, gold and silver metal recoveries, the potential to produce a precipitate or metal on site replacing the current ore concentrate that is produced at Caribou – which, if implemented, would lead to savings on transport costs and offsite treatment costs – and the opportunity to process historic mill tailings, which include gold and copper metals, in addition to run of mine ore. The latter would increase revenues and reduce closure liabilities, Trevali said.

Trevali says the use of FLSmidth’s ROL technology also provides the potential to reduce Trevali’s carbon footprint at Caribou and extend Caribou’s mine life and treat lower-grade deposits in the Bathurst camp of Canada.

FLSmidth says ROL leaches 97-99% of copper directly on-site in six to eight hours, from concentrates as low as 5% Cu. In gold, ROL has the potential to unlock the value of undeveloped refractory gold deposits with less than 3 g/t gold head grade, it says.

Unlike other refractory processing techniques, the ROL process uses the application of mechanical energy coupled with oxidation under atmospheric conditions. The process relies on stirred media reactors to accelerate the oxidation of sulphide minerals. This eliminates the need for ultrafine grinding, high temperatures and high pressure which makes it energy saving and very cost-effective, according to the mining OEM.

Trevali said a successful pilot plant test program using ROL may allow Trevali to replace the existing flotation circuit at Caribou with atmospheric leach vessels and potentially an SX/EW train, introducing the possibility of producing base and precious metals on-site and thereby save transport costs and offsite treatment costs.

Conceptual objectives of the program include:

  • Recovery of metals/minerals that are not recoverable using the current technology at Caribou (precious metals and magnetite); and
  • Improved payables/selectivity of the traditional flotation process using new and emerging technologies.

Ricus Grimbeek, President and Chief Executive Officer of Trevali, said: “FLSmidth’s ROL metallurgical technology has the potential to transform the Caribou mine and the wider Bathurst Mining Camp.

“This next phase of the testing program is an essential step in evaluating the suitability and economic viability of a processing solution with the potential to enhance the value of the in-situ material and tailings at Caribou as well as the surrounding deposits in the Bathurst region. The positive results to date support further study and analysis given the potential implications for the Bathurst Mining Camp in general and Trevali in particular.”

Beyond quantifying the ability to recover additional metal values, the objective for the pilot plant test program is to determine the various kinetic factors, mass and energy balance and engineering data to support future engineering on a preliminary economic assessment for potential processing of the Trevali mill feed and mill tailings and produce metal on site.

Continuous pilot plant trials commenced in June 2021 (Phase 1) to tune the pilot plant and provide material for precious metal leach tests in late July, followed by a test program at the Caribou Mine site that is planned for September 2021 (Phase 2). Leach data and results are expected to verify that batch testing results can be achieved in a continuous operation.

GR Engineering to help double processing capacity at NSR’s Thunderbox

GR Engineering Services says it has executed an engineering, procurement and construction (EPC) contract with Northern Star Resources in relation to the Thunderbox 6 Mt/y expansion project in Western Australia.

Located 45 km south of Leinster, the Thunderbox operations currently have a 3 Mt/y processing capacity. The asset was owned by Saracen Mineral Holdings prior to a merger with Northern Star.

The works will involve the design, engineering, procurement, construction and commissioning of the project, with the contract sum amounting to A$101 million ($74.3 million) and work is expected to start immediately.

GR Engineering has carried out several projects on the Thunderbox operations, including EPC work on the Thunderbox paste plant work, which has seen a new 150 cu.m paste backfill plant built.

Commenting on the recent award, Geoff Jones, GR Engineering Managing Director, said: “GR Engineering is excited to continue working with Northern Star, one of the world’s leading gold producers, to safely deliver the Thunderbox Expansion project. We have worked with the Northern Star team over many years and see this award as a strong endorsement of our proven EPC delivery capability.”

On award of Northern Star’s largest infrastructure project to date, Northern Star’s General Manager Processing, Simon Tyrrell, said: “The Thunderbox expansion increases the operation’s hard-rock processing capacity to 6 Mt/y from the current 3 Mt/y, and decreases processing costs as outlined in the 2021 Investor Day Presentation. Northern Star is pleased to be working with GR Engineering again, a local company with vast project delivery experience in the Australian mining industry.”

In this same presentation, the company said the processing capacity boost would involve the addition of a new 18 MW mill and classification circuit; new leach tanks, elution and gold room upgrades; and new tailing thickener and tailings pumping. The plant would be designed for 100% fresh ore, NSR said.

NRW’s METS business takes flight with Primero’s latest contract awards

The first build own operate (BOO) contract initiatives, and the first major engineering, procurement, site support and commissioning contract in West Africa are some of the highlights from Primero Group’s latest contract awards.

The company, acquired by NRW Holdings earlier this year, has recently been awarded new contracts totalling circa-A$155 million ($114 million) with key clients. It has also progressed strategic initiatives that provide further strength to the group offering within the newly formed Minerals, Energy and Technology (METS) business under the NRW Holdings banner, NRW said. RCR Mining Technologies and DIAB Engineering also feature under the METS business.

“These include the award of the group’s BOO contract initiatives crystalising the strategic direction deployed by the group to enter the market of ownership and operation of processing infrastructure,” it said. “The equipment is designed, fabricated and constructed internally utilising the METS division companies and focuses on enabling the infrastructure to be relocatable, in alignment with other material handling products already being offered by the group.”

Primero has been awarded two key contracts with Mt Gibson Iron. The first is for the upgrade of the Koolan Island crushing circuit under an engineering and construction contract off the coast of Western Australia. The second is a two-year fixed crushing contract at the Shine development project in the Mid-West region of Western Australia under a BOO arrangement, with an option to extend.

Also, in the iron ore space and Western Australia, Primero has been awarded a four-year contract for crushing services at Atlas Iron’s proposed Miralga Creek operation in the Pilbara region. The contract provides crushing services for 2 Mt/y under a BOO scenario and will commence in early 2022.

In West Africa, meanwhile, Primero has secured its first major engineering, procurement, site support and commissioning contract for the Abujar gold project in Côte d’Ivoire, owned by Tietto Minerals. “The project award demonstrates the groups continuing growth and maturity in minerals processing engineering execution and diversity in capability across multiple commodities in the group,” NRW said.

The project is at a 3.5 Mt/y throughput scale with most of the contract revenue to be recognised in NRW’s 2022 financial year.

Back in Western Australia, meanwhile, Primero has been awarded the Mt Holland water supply pipeline construction contract from Covalent Lithium. The project follows on from the design services that Primero was awarded in October 2020 and completed including detailed construction planning and methodology for the 130 km pipeline and associated pumping facilities.

Site construction works have commenced, and the project is scheduled for completion in the March quarter of 2022.

As an updated note, Primero confirms the previously announced letter of intent with Panoramic Resources for the contract operations of the Savannah Nickel project has been finalised into a binding contract with a term of three years, as per Panoramic announcement dated April 6, 2021.

Work has already commenced in the preparation and operational readiness for the recommencement of the concentrator operations in-line with the announced restart plan of the mine in the September quarter with first shipments planned in December.

NRW CEO, Jules Pemberton, said: “The ongoing development of the METS pillar of the NRW Holdings Group is continuing to provide further success and market penetration within key client groups in our sector. Primero, as the newest addition to that group, has added significant capability and these recent contract awards showcase the diversity, capability and the expanding capacity of the group across multiple commodities and services.”

Scantech launches GEOSCAN GOLD to help digitalise and control ore quality

Scantech International Pty Ltd has released GEOSCAN GOLD, a premium elemental analyser that, it says, uses the highest specification PGNAA (prompt gamma neutron activation analysis) technology available.

The analyser, which builds on Scantech’s GEOSCAN-M high-performance elemental analyser, provides previously unattainable levels of risk-free, real-time measurement performance to the resources sector to help digitalise and control ore quality, according to the company.

GEOSCAN GOLD provides high-quality, real-time elemental analysis for conveyed flows where precision and short measurement times are essential for optimal control. This makes it ideal for bulk diversion (bulk sorting) and fine control where elements at parts per million levels need to be measured or determined from proxies such as gold, platinum group elements, silver and toxic contaminants (eg mercury, cadmium, chlorine, etc), Scantech says.

The analyser incorporates a high performance proprietary detector array for a “better, cleaner spectrum” at lower concentrations for superior element recognition. The array overcomes limitations of conventional, low efficiency detection systems, according to Scantech. It can also operate at extremely high count rates with negligible pulse pile-up.

“This innovation vastly improves the signal to noise ratio and spectral peak resolution, enabling elemental detection at lower levels,” the company said.

Just some of the advantages of GEOSCAN Gold that Scantech highlighted include:

  • An ultra-compact design that can install between standard idlers;
  • Unmatched proven performance;
  • Operational at completion of commissioning;
  • Customised calibrations;
  • Three models cater for belts 600 mm to 2,400 mm and bed depths to 530 mm;
  • No contact with material or conveyor belt;
  • No sampling necessary during normal operation;
  • No wear parts, therefore, low maintenance requirements;
  • Optional customised SUPERSCAN console;
  • Interface to most process control systems; and
  • Proven short paybacks in many applications (bulk diversion, blending, monitoring, feed forward, etc) to optimise plant performance.

The company says GEOSCAN GOLD measures elements in primary crushed rock in conveyed flows at <100 t/h to >10,000 t/h irrespective of belt speed, particle size, mineralogy, dust, moisture, or segregation/layering,

It covers most elements from carbon onwards in the periodic table, including gold, over various measurement times and concentration levels. It can also analyse selected elements to below 1 parts per million, and even register accurate results where conveyor belts contain chlorine or steel cords.

It can register gold directly over 5-10 minute increments and other elements, including proxies for gold (eg sulphur, copper, etc), with high precisions over each 30 seconds of flow.

Measurement data is used concurrently for various applications: bulk sorting, ore blending, ore reconciliation, ore tracking, feed forward control, metal accounting, etc.

“GEOSCAN GOLD is the new standard in representative, real time, conveyed material measurement using Scantech’s Rocks2data customisation module,” the company said. “Successful performance is already proven in many challenging bulk ore sorting applications in base metals and PGMs. It builds on the very successful, world-leading GEOSCAN-M with over 100 installations in the minerals sector in more than 10 commodities. Paybacks are in a few months and sometimes weeks. Non-contact design minimises maintenance and remote access ensures trouble-free operation and high data accessibility.”

Yamana Gold retains electrification path for Wasamac in new study

Yamana Gold has reiterated a plan to minimise the amount of carbon emissions generated with the development and operation of the Wasamac gold project in Quebec, Canada, in its first study since acquiring the asset from Monarch Gold.

Monarch, prior to being taken over by Yamana Gold, had laid out plans for an underground mine at Wasamac producing 6,000 t/d, on average, with an expected mine life of 11 years. It expected to use a Rail-Veyor® electrically powered, remote-controlled underground haulage system in addition to an almost entirely electric fleet of production and development equipment.

The December 2018 feasibility study by BBA indicated the Wasamac deposit hosted a measured and indicated mineral resource of 29.86 Mt at an average grade of 2.7 g/t Au, for a total of 2.6 Moz of gold, and proven and probable mineral reserves of 21.46 Mt at an average grade of 2.56 g/t Au, for a total of 1.8 Moz of gold. The study forecast average annual production of 142,000 oz of gold for 11 years at a cash cost of $550/oz.

With drilling, due diligence and further studies, Yamana Gold, in studies forming the new feasibility level studies, has come up with baseline technical and financial aspects of the Wasamac project that, it says, underpin the decision to advance the project to production.

This has resulted in a few changes to the Wasamac plan.

For starters, the company plans to use the extract the now 1.91 Moz of reserves quicker than Monarch’s strategy, with a rapid production ramp-up in the first year followed by sustained gold production of approximately 200,000 oz/y for at least the next four years.

Including the ramp-up phase, average annual production for the first five years of operation is expected to be 184,000 oz, the company said, with life of mine production of 169,000 oz/y. Mill throughput has been increased to 7,000 t/d, on average, but the plant and associated infrastructure were being sized for 7,500 t/d. Production could start up in the December quarter of 2026, the initial capital expense was expected to be $416 million and all-in sustaining costs over the life of mine had been calculated at $828/oz.

The use of a conveyor is still within this plan, but a company spokesperson told IM that Yamana was now considering a conventional belt conveyor rather than the Rail-Veyor system.

Yamana explained: “The optimised materials handling system uses ore passes and haul trucks to transport ore from the production levels to a central underground primary crusher. The haul trucks will be automated to allow haulage to continue between shifts. From the underground crusher, ore will be transported to the crushed-ore stockpile on the surface using a 3-km-long conventional conveyor system in two segments.”

Yamana added: “Using a conveyor rather than diesel trucks to transport ore to surface reduces CO2 emissions by 2,233 t/y, equivalent to taking 500 cars off the road. Over the life of mine, the company expects to reduce CO2 emissions by more than 20,000 t.”

The aim to use electric vehicles wherever possible remains in place.

“The Wasamac underground mine is designed to create a safe working environment and reduce consumption of non-renewable energy through the use of electric and high-efficiency equipment,” the company said. “Yamana has selected electric and battery-electric mobile equipment provided that the equipment is available at the required specifications.

“Battery-electric underground haul trucks are not yet available at the required capacity with autonomous operation, so diesel trucks have been selected in combination with the underground conveyor. However, Yamana continues to collaborate with equipment suppliers with the expectation that the desired battery-electric equipment will be available before Wasamac is in operation.”

In tandem with this, the company plans to use a ventilation on demand solution and high-efficiency fans to reduce its power requirements. This will likely rely on an underground LTE network.

“Heating of the underground mine and surface facilities is designed with the assumption of propane burners, but an opportunity exists to extend the natural gas line to the project site,” it added. “Yamana has initiated discussions with the natural gas supplier and will study this opportunity further as the project advances.”

The site for the processing plant and offices is confined to a small footprint strategically located in a naturally concealed area, and the processing plant has been designed with a low profile to minimise the visual impact as well as minimise noise and dust, according to Yamana.

The primary crusher, previously planned to be located on surface, has been moved underground, with the crushed material transported to surface from the underground mining area using conventional conveyors and stored on surface in a covered stockpile to control dust.

Several design improvements to the previous Wasamac plans have also been made to reduce consumption of fresh water to minimise the effect on watersheds, according to Yamana. Underground mine water will be used in the processing plant, minimising the draw of fresh water and reducing the required size of the mill basin pond.

The Wasamac tailings storage strategy is designed to minimise environmental footprint and mitigate risk, it added.

“Around 39% of tailings will be deposited underground as paste fill and 61% of tailings will be pumped as a slurry to the filter plant located approximately 6 km northwest of the processing plant and then hauled to the nearby dry-stack tailings storage facility,” Yamana said.

Strategic phasing of the tailings storage facility design allows for the same footprint as previously planned, even with the increase in mineral reserves, the company clarified. Also, the progressive reclamation plan for this facility minimises the possibility of dust generation and expedites the return of the landscape to its natural state.

New Gold to collaborate with MineSense in underground ore sorting move

MineSense is gearing up for a move underground with the help of New Gold and its New Afton gold-copper mine in British Columbia, Canada.

The Vancouver-based technology company has already established and proven its ShovelSense technology for the open-pit mining sector, with its X-ray Fluorescence (XRF) sensor-based system now operating on shovels, wheel loaders and excavators on a commercial basis across six operating mines. This includes large installations at Teck’s Highland Valley and Copper Mountain’s copper operations in BC, as well as one ShovelSense unit at the Antamina copper operation in Peru.

Designed for operation in extreme environments and retrofits on any existing mobile equipment, ShovelSense units come equipped with a human machine interface and proprietary algorithms that measure and report ore grade/characteristics. They can also connect directly to fleet management or other existing control software systems, enabling mine operators to reconcile geological block models with actual ore grade data.

Having finetuned the system for above-ground operations, the company is now embarking on its underground move, according to MineSense President and CEO, Jeff More.

A trial of the underground ShovelSense system at New Gold’s New Afton mine is first up to complete product development. The company will be installing a unit on a Cat R1600G LHD for this step. This will be followed closely by installation at a “large entity” in Chile – with More anticipating start up in the September or December quarter.

The development agreement with New Gold at the BC-based mine is looking to trial and finetune the system for underground operations, with More confident the ShovelSense system will stand up to the test.

“The core technology – all of the algorithms, software, hardware – is the same as ShovelSense for open-pit mining,” More said. “It is the ‘application package’ – looking at how we can attach the unit to the machine and protect it in an underground environment – that is what we have to test out. The design for this is already complete; it’s just a matter of trialling it.”

New Afton represents a good test for the system.

New Afton is Canada’s only operating block cave mine, with the New Afton deposit part of a larger copper-gold porphyry district in the region. The operation regularly mines 15,000-16,000 t/d of ore and waste, with the majority of this currently going to the mill.

The company has already pursued “ore segregation” projects to boost the grade of material being fed through to the processing side, but the move into the higher-grade C-Zone in 2023-2029 will place an even greater emphasis on ore/waste boundaries and milled tonnes at the operation.

At the same time, the ShovelSense deployment at New Afton will represent the first time MineSense has sent a unit into a mine that has so much payable gold, with most operations the company has worked on being primarily base metal-oriented.

In 2020, New Afton produced 64,000 oz of the yellow metal, along with 32,659 t of the red metal.

“This will be the first time we’re touching gold at this level; we have other mines that have payable gold but not at that level,” More explained.

In New Afton’s case, sampling and historical data has proven that the orebody’s copper and gold ratios tend to be consistent and unchanging over the long term. With this knowledge, New Afton has used technology in the past to determine the copper value and make ore/waste production decisions. ShovelSense allows New Afton to move the ore/waste production decision to the drawpoint, according to MineSense. This reduces mixing and blending during the crushing and conveying circuit which can homogenise the material to the point where it is not worth segregating.

Trialling new technology such as this is nothing new for New Afton.

The operation already uses automated loading through Sandvik’s AutoMine solution, is employing electrification with the use of Sandvik and MacLean Engineering battery-powered mobile equipment, and, in the process plant, has Gekko Systems’ highest volume InLine Pressure Jig IPJ3500 to improve gravity concentration.

More says the ShovelSense unit could be in the Cat LHD bucket at New Afton in August, with the machine then going through an above-ground trial ahead of the underground transition at the end of September.

“By early Q4, we should have completed the pilot,” he said.

Macmahon defies labour tightness to bolster contract mining order book

Macmahon Holdings Ltd has added around A$1.35 billion ($988 million) of work to its order book with the signing of three previously flagged contract mining gigs, plus announced the addition of surface mining work at Northern Star Resources’ Julius gold project in Western Australia.

The three projects making up the A$1.35 billion of contract mining works are the 5-year agreement with St Barbara Ltd at the Gwalia gold mine, a three-year pact with Anglo American at Dawson South and a five-year contract with Red 5 Ltd at King of the Hills.

The contract with Northern Star Resources at Julius is expected to deliver revenue of A$25 million over the next 12 months. Production from the Julius deposit is expected to complement output from NSR’s Jundee operations.

In addition to these projects, Macmahon says it is well progressed in finalising the commercial arrangements for Phase 8 of its Batu Hijau copper-gold project in Indonesia, an operation owned by PT Amman Mineral Nusa Tenggara.

Macmahon commented: “While Macmahon has observed a tightening of the labour market in Australia over the past year, it can confirm that the Gwalia, Dawson South and Julius projects have commenced operations by the times required in those contracts.

“Macmahon has existing strategies for responding to challenges in the availability of labour, and believes it is well placed to continue to manage this operational issue into the foreseeable future, and to continue to deliver value for its clients.”

Commenting on today’s announcement, Macmahon CEO and Managing Director, Michael Finnegan, said: “Macmahon is continuing to build on its track record for delivery and to advance its growth strategy.

“It is very satisfying to have secured significant new work during financial year 2021, which provides us with a strong order book and excellent earnings visibility for FY22 and FY23. The underground work at Gwalia and King of the Hills also adds scale to our underground business, which is an important step in our strategy to diversify Macmahon.”

Newmont to add to Ghana gold production with Ahafo North development

Newmont Corp’s Board of Directors has approved advancing the Ahafo North project, in Ghana, into the execution phase, setting the company up to develop four open-pit mines and a standalone 3.7 Mt/y plant.

The project exceeds the company’s required internal rate of return, adding profitable production from the best unmined gold deposit in West Africa, it said.

Newmont President and CEO, Tom Palmer, said: “I am pleased to announce the approval of full funding for the Ahafo North project, expanding our existing footprint in Ghana and adding more than 3 Moz of gold production over an initial 13-year mine life. The development of this prolific orebody will leverage our proven operating model and will be supported by our existing world-class Ahafo South operation.

“The project will be developed and operated in a sustainable and responsible manner to create value for all our stakeholders.”

Located some 30 km north of Newmont’s existing Ahafo South operations (pictured) – which are expected to produce 515,000 oz of gold this year – Ahafo North’s production is expected to average approximately 275,000-325,000 oz/y with all-in sustaining costs of $600-$700/oz for the first five years. Projected capital costs are estimated to be between $750-$850 million with construction expected to be complete in the second half of 2023. At current gold prices, the project is expected to deliver more than a 30% internal rate of return, Newmont said.

The project will create approximately 1,800 jobs at the peak of construction with more than 550 permanent roles created once the mine is operational.

“Newmont will work to create lasting value for host communities through local sourcing and hiring,” the company said, adding that a key aspect of the Ahafo North project’s workforce planning will be a target to achieve gender parity in the workforce when operations begin.

The full scope of funding will be deployed to high-impact activities, including but not limited to finalising engineering and EPCM services, relocating the national highway and support of additional resettlement activities, mining development for four open pits, constructing and commissioning a 3.7 Mt/y plant, constructing a tailings and wastewater management storage facility, long-lead sourcing including the acquisition of 14 Caterpillar 770 haul trucks.

Ivanplats to trial Epiroc battery-electric drills and LHDs at Platreef mine

Epiroc says it has won a significant order for battery-electric mining equipment from Ivanplats that will be used to develop its greenfield Platreef mine in South Africa in the “most sustainable and productive manner possible”.

Ivanplats, a subsidiary of Canada-based Ivanhoe Mines, has ordered several Boomer M2 Battery face drill rigs and Scooptram ST14 Battery LHDs (pictured).

These machines will be trialled during the Platreef underground mine’s initial development phase, Epiroc said, adding that Ivanplats has the ambition to use all battery-electric vehicles in its mining fleet at Platreef.

The order exceeds ZAR150 million ($10.2 million) in value and was booked in the June quarter of 2021.

Ivanhoe indirectly owns 64% of the Platreef project through its subsidiary, Ivanplats. The South Africa beneficiaries of the approved broad-based, black economic empowerment structure have a 26% stake in the project, with the remaining 10% owned by a Japanese consortium of ITOCHU Corporation, Japan Oil, Gas and Metals National Corporation, and Japan Gas Corporation.

The Platreef 2020 feasibility study builds on the results of the 2017 feasibility study and is based on an unchanged mineral reserve of 125 Mt at 4.4 g/t 3PGE+Au, project designs for mining, and plant and infrastructure as in the 2017 study; except with an increased production rate from 4 Mt/y to 4.4 Mt/y, in two modules of 2.2 Mt/y, for annual production of more than 500,000 oz of palladium, platinum, rhodium and gold; plus more than 35 MIb of nickel and copper.

The initial plan is to start at a mining rate of 700,000 t/y before scaling up. An updated feasibility study on the plan is expected to be published before the end of the year.

Helena Hedblom, Epiroc’s President and CEO, said it was “encouraging” that Ivanplats is considering going all battery-electric at Platreef.

“Battery-electric equipment is increasingly embraced by mining companies as it provides a healthier work environment, lower total operating costs and higher productivity,” she said. “The technology is now well established, and Epiroc is driving this change toward emissions-free mining.”

Marna Cloete, Ivanhoe Mines’ President and CFO, said: “We want to be at the forefront of utilising battery electric, zero-emission equipment at all of our mining operations. This partnership with Epiroc for emissions-free mining equipment at the Platreef Mine is an important first step towards achieving our net-zero carbon emissions goals while mining metals required for a cleaner environment.”

Boomer M2 Battery face drill rigs and Scooptram ST14 Battery loaders are built in Sweden, and are automation-ready and equipped with Epiroc’s telematics solution Certiq.

The equipment will be delivered early to Platreef in 2022. Epiroc will also provide on-site operator and maintenance training to Ivanplats, it said.

Epiroc intends to offer its complete fleet of underground mining equipment as battery-electric versions by 2025, and its full fleet for surface operations as battery-powered versions by 2030.

RUC Cementation bolsters Edna May fleet with Sandvik Toro LHD

RUC Cementation Mining Contractors has acquired a new Sandvik Toro™ LH517i loader for its underground mining operations, looking to deploy it at Ramelius Resources’ Edna May gold operation in Western Australia.

The Toro LH517i loader represents the latest in LHD technology to improve performance and reliability as well as enhanced machine data and performance analytics, RUC Cementation said.

Barry Upton, RUC Cementation Managing Director, said the company was pleased to take delivery of the new machine, which is planned to significantly enhance LHD performance across the fleet at Edna May, and it was looking forward to tapping into the benefits the intelligent series of loaders was able to offer.

The Toro LH517i loader is a matching pair with the Sandvik TH551i truck, considering the designed payload capacities.

It features the latest Sandvik Intelligent Control System and My Sandvik Digital Services Knowledge Box™ on-board hardware as standard. The unit is also fully ready for automation, requiring just a few days for AutoMine® retrofit implementation, according to Sandvik.

The Edna May operation produced 26,632 oz of gold in the June quarter.
