Torex Gold’s Media Luna project in Mexico has been behind a surge of battery-electric vehicle contract activity of late, with the latest recipient being Saskatoon-based Rokion.

The gold mining company has ordered a 28-strong fleet of BEVs from Rokion, set to start being delivered at the back end of the year.

These vehicles will be crucial in providing zero emission and effective personnel transport and production support functions at the project, which is set to extend the life of mine of its El Limón Guajes (ELG) Complex through at least 2033.

Media Luna is located 7 km south of the existing ELG Complex comprised of the El Limón, Guajes and El Limón Sur open pits, El Limón Guajes underground mine, plus the processing plant and related infrastructure. It is an underground deposit primarily containing gold, copper and silver mineralisation, separated from the ELG Complex by the Balsas River.

The underground mine is designed for an average production capacity of 7,500 t/d, predominately using a mining method of longhole stoping with paste backfill, supplemented by mechanised cut and fill stoping where appropriate. It will be a fully mechanised operation with the primary access to the mine via the Guajes Tunnel, which, itself, will have a length of approximately 6.5 km, creating an underground connection between the ELG Complex and the Media Luna mine. The ELG site will continue to serve as the base of mine operations, with all production levels accessible from the internal mine ramp.

Torex expects to bring Media Luna into commercial production in early 2025, ramping up to 7,500 t/d by 2027 and creating one of Mexico’s largest underground mines. It contains reserves of approximately 2.1 Moz gold, 18.9 Moz silver and 444 Mlb copper.

As of March 31, 2023, physical progress on the project was approximately 24%, according to Torex, with detailed engineering, procurement activities, underground development and surface construction advancing. The project continued to track to overall schedule and budget, the company noted.

Equipment deliveries will be key in advancing the project in line with the schedule and, earlier this year, both Sandvik Mining and Rock Solutions and MacLean announced sizeable equipment orders – both battery- and diesel-powered – related to the mine’s development and production phases.

Now, IM can reveal that Torex has also sealed an agreement with Rokion.

Rokion are to supply 27 of its battery-powered utility trucks to the operation along with one R700 forklift – the latter representing the company’s first order for a battery-powered forklift.

According to Rokion, these trucks can navigate mine sites with 20% grade at a full gross vehicle weight and full speed while traveling more than 70 km per charge. This is more than enough to get through a full shift without charging. And, while availability is a key selling point, Rokion says its battery-powered vehicles have been designed for simple and easy maintenance. The modularity of the components are “ideal for remote mining locations where the priority is to have dedicated service personnel with expertise in production mining equipment”.

When it comes to vehicle specifics, Rokion outlined that Torex would receive 10 R200 battery-powered trucks – configured to carry up to five passengers – two R200 trucks set up as two-passenger surveyor utility vehicles, two R200 two-person “6×6 Surveyor” utility vehicles and four R200 two-person “6×6 Electrician” utility vehicles. This would be complemented by seven R400 vehicles fitted out to carry 12 passengers – which have four-wheel steering to greatly improve manouevrability, according to Rokion – and two R400s equipped for three passengers able to carry out mechanic duties.

The Rokion order from Torex for Media Luna includes 16 of the company’s R200 battery-electric vehicles

Gertjan Bekkers, Vice-President, Mines Technical Services with Torex, said: “Our light-vehicle fleet will be used to drive fairly significant distances between our work sites on every shift, so the flexibility and range of these vehicles were key considerations for Torex during the procurement phase. The tunnel connecting Media Luna with ELG is like our horizontal shaft, connecting to the internal ramp of the Media Luna mine. Of course, we’ve also carefully considered equipment reliability and we were particularly impressed by the enhancements that Rokion has made to their portfolio since entering the underground hard-rock mining market.”

Kipp Sakundiak, CEO of Rokion, said the two companies have struck up a very important partnership over the last year or so when the engagement began.

“After getting to know the team at Torex, we are excited about the opportunities,” he told IM. “It is a good thing when you have a vendor-supplier relationship whereby both companies share similar values.”

Deliveries of the vehicles will start in October, with the full fleet set to be in place in 2025, according to Sakundiak.

LDO Group’s Rokion battery-electric light vehicle refocus starts to pay off

LDO Group is making serious headway in deploying Rokion’s ground-up-design electric light vehicles across Australia, with the New South Wales-based distributor hoping to have three machine trials in place before the end of the year.

LDO is focused on the underground mining and tunnelling industries, specialising in systems, processes, mine planning and training. It has been the exclusive distributor of Canada-made Rokion battery-powered vehicles in Australasia since 2018, having deployed vehicles across the soft- and hard-rock space.

The latest Rokion deployment LDO Group is celebrating is at Agnico Eagle Mines’ Fosterville gold operation in Victoria where a Rokion R400 was recently shown off alongside a Sandvik LH518B at a launch ceremony at the gold operation.

Alan Ross, General Manager of LDO Group, said the R400 vehicle – a platform able to accommodate three passengers in a utility vehicle setup or up to 12 in a passenger crew variant – has been deployed as part of a six-month trial at the operation.

“They (the Fosterville team) plan to use this in a people carrier configuration,” Ross told IM. “It will transport people to and from the operation.”

Considering the ramp-supported Fosterville operation goes below 800-m depth, this will present a good test for the R400’s re-generation capacity and uphill performance.

Rokion says the vehicle, which has 100 kWh of battery capacity, was engineered for the demands of underground mining and is its most adaptive platform design, capable of transporting a large crew in mine applications. Like all Rokion vehicles, it incorporates lithium iron phosphate battery chemistry, which, the company says, is the safest battery chemistry currently available.

The vehicle heading underground at Fosterville was previously deployed at a coal mining operation in Queensland, yet Ross says LDO Group is now re-focusing its efforts on the hard-rock mining space.

This has already seen the company partner with Newmont on an R400 deployment at its Tanami underground operation in the Northern Territory of Australia where it was initially used to transport team members up and down the mine.

Newmont said last year that early indicators had shown the vehicle had the capability to complete several trips to and from the bottom of the Tanami mine without requiring recharging.

Ross agreed with the Newmont assessment, explaining that the company was expected to re-deploy the same unit to the Tanami operation with an additional battery cooling module later this year.

“The ambient temperatures can reach 50°C in the Tanami desert, so we have equipped the vehicle with this new module to cope with such extremes,” he explained.

The company also has two R200 units – which include a four-passenger crew truck and a two-passenger utility truck – in Australia awaiting redeployment. One of these vehicles recently completed a successful stint at a tunnelling operation in the country.

LDO is also engaged with another mining company with an operation in New South Wales seeking to trial Rokion’s smallest battery-electric platform, the R100.

The R100 series includes a four-passenger crew truck and a two-passenger utility truck, with both models built on the same frame dimensions and available in ramp-ready configurations.

“We’re currently focused on these three key customers and supporting them in terms of the deployments and on-going operations,” Ross said.

In addition to regular site visits from LDO personnel to support maintenance and operations staff at the underground mines, LDO staff are able to remotely download data logs for these machines on a daily basis, assessing if there is potential for optimising the operation or if maintenance work may need to be conducted.

With many companies in the battery-electric light vehicle conversion space in Australia struggling to get hold of donor diesel vehicles, Ross says mining companies are increasingly appreciating Rokion’s ground-up approach.

“We have a fantastic OEM partner to rely on for these vehicles and we at LDO are able to support them in the best possible way,” he said. “We don’t have to rely on a different vendor to obtain the base machine; the design, engineering, manufacturing and testing are all performed under the Rokion roof, ensuring quality from concept to delivery.”

Ross said Rokion is continually working on design improvements and new machines based on industry feedback, with a newly-designed R200 vehicle set to bridge the gap between the existing R200 and the larger R400.

The latest in Rokion’s R200 Series is an 11-passenger crew truck built on a heavier frame and suspension construction than previous models, Kipp Sakundiak says

Kipp Sakundiak, CEO of Rokion, was happy to provide more details of this to IM: “The latest in our R200 Series is an 11-passenger crew truck built on a heavier frame and suspension construction than our previous models, all the while maintaining the simplicity and performance of dual drive motors.”

Sakundiak said the new model was robust and powerful, at the same time offering a comfortable ride for all crew members.

He added: “There is a lot of adaptability built into the new platform, including configurations for soft- and hard-rock applications. It’s one of our most versatile designs.”

Rokion battery-powered vehicles hit new depths at Vale Creighton

As Vale continues to go deeper at its Creighton nickel mine, in Sudbury, Canada, it is adopting alternatives to its fleet of diesel-powered haulage, loading and utility vehicles in a bid to lower operating costs and improve environmental conditions for personnel that could eventually be working nearly 3 km underground.

Vale’s PowerShift strategy, part of the miner’s 2030 sustainability goals, aims to make the company’s energy matrix “clean” by focusing on the use of renewable energy and alternative fuels, greater efficiency of operations using new technologies, and forest promotion. As part of this strategy, it will test and adopt existing ‘green’ solutions as well as develop technologies with the potential for greater impact on its carbon footprint.

This has involved the use of Rokion’s battery-powered personnel carriers/utility vehicles at Creighton.

The company has been working with Rokion for close to two years after placing an order for three of its vehicles for the Creighton mine. Alongside these vehicles are other battery-powered haul trucks, loaders and production support machines supplied by the likes of Epiroc and MacLean Engineering. All these machines are being added to the fleet as the company looks to access deeper, more ventilation-constrained areas of the mine.

Todd Van Den Enden, Process Superintendent at Creighton Mine, told IM recently that the Rokion R100, R200 and R400 units had been “very well received at Creighton Mine” and the company had moved forward in purchasing more of these units to further its battery-electric vehicle development at the operation.

The units are currently used by Vale’s service groups – such as industrial mechanics, electrical and planning departments – and generally run for the entirety of a 10.5-hour shift.

The ramps at Creighton, which go from 15-20% on both the incline and decline, according to Van Den Enden, will aid the continual operation of these battery-powered machines. Equipped with lithium-iron phosphate battery technology, the Rokion units recharge their batteries on descent thanks to regenerative braking. This translates to not only a longer operating time without charge, but also greater savings per vehicle over the life of the mine, according to Rokion.

Rokion trucks can navigate mine sites with 20% grade at a full gross vehicle weight and full speed while traveling more than 70 km per charge, according to the company. This is more than enough to get through a full shift without charging.

This means the vehicles are typically only charged after the 10.5-hour shift is complete at Creighton, according to Van Den Enden. The larger R400 (pictured), which includes a six- to 12-passenger crew truck and a three- to nine-passenger utility option, has completed two shifts on a single charge during testing.

When charging is required, the Rokion units can rely on existing mine power infrastructure, with the charging procedure no different to the way people top up the charge on their Tesla vehicles, Rokion says. The company worked within the Global Mining Guidelines Groups’ BEV guidelines to design this standardised system.

Vale’s Van Den Enden said the operation of both the R100, which includes a four-passenger crew truck and two-passenger utility truck option, and the R200, which has a four-passenger crew truck and two-passenger utility truck option, has “exceeded our expectations”.

He explained: “We have roughly 1,200 hours on these units and we see advantages with the availability.”

While availability is a key selling point, Rokion says its battery-powered vehicles have been designed for simple and easy maintenance. The modular change-out options – which extend to both the battery and drive system – are “ideal for remote mining locations where the priority is to have dedicated service personnel with expertise in production mining equipment”.

Rokion explained: “A mine is not going to hire an expert in battery power when introducing a new truck such as this, so we take that aspect out of the equation, compartmentalising our battery systems into a modular form so that they can be easily switched out.”

Mine operators can visualise the operation of their vehicle assets by accessing a live fleet management system that streams data between the truck and site operations team, according to Rokion. This helps customers identify vehicles that are low on power or may need servicing. Customers also have the option of having this data routed to Rokion for additional support, the company says.

“Managing this data into useful information has become a valuable tool in helping to improve operational efficiencies for our customers,” the company said.

While there is the very real prospect of Rokion selling more units to Vale’s Creighton operation, it is also working with the miner on refining its latest R400 unit, which, it says, was engineered to be the company’s most adaptive and modular truck platform.

Van Den Enden said the R400 unit was just finishing up the testing phase with the Creighton mining department, with the machine having performed well. He said the two firms were currently working on a “minor update” for the next series of this unit.
