IAMGold weighs autonomous drilling, haulage at Côté gold project

IAMGold has provided an update on its majority-owned Côté gold project in Ontario, Canada, which included confirmation of a key approval and the mention of studies on implementing autonomous haulage and drilling technologies.

The late 2018 feasibility study on the project demonstrated its potential to produce 460,000 oz/y of gold at all-in sustaining costs of around $700/oz for the first six years of a 16-year mine life.

It said this week that the project has received approval for its application under Section 36 of the Fisheries Act (Canada). This is a key milestone in attaining permits relating to impacts on fish habitats and tailings management, according to the company.

Since the feasibility study was published in late 2018, IAMGold says it has been very active in “de-risking” the project.

As of the end of May, the company says it has:

  • Completed additional resource and geotechnical studies, and advanced mine planning;
  • Completed over 60% of detailed project engineering, including the tailings facility;
  • Following this level of engineering, obtained firm bids and secure prices on all major equipment. To date, 55% of project cost has firm pricing, further reducing technical and cost risks for the project leading to a refinement in costs and metrics as IAMGold works toward a construction decision;
  • Completed a pre-construction camp on the adjacent Chester site;
  • Completed all tree clearing needed for initiating construction – work was carried out with a First Nations partner firm earlier in 2020, before standing down in respect of the COVID-19 pandemic;
  • Carried out detailed implementation studies on technology, including automated truck haulage and drilling, and commenced discussions with regulators regarding the use of automated equipment;
  • Advanced development of construction protocols in consideration of COVID-19; and
  • Completed 4,700 m of drilling at the Gosselin Zone, a potential satellite pit 1.5 km northeast of Côté.

The company has also signed Impacts and Benefits Agreement with First Nations partners, approved the Environmental Assessment and Closure Plan, and advanced permitting.

The 2018 feasibility study envisaged a truck-shovel operation, assuming 220 t autonomous trucks and 34 m3 shovels, and a 36,000 t/d mineral processing circuit incorporating primary crushing, secondary crushing, tertiary high pressure grinding roll crushing, ball milling, vertical stirred milling, gravity concentration and cyanide leaching, followed by gold recovery using carbon-in-pulp, stripping and electrowinning.

Gordon Stothart, IAMGold President and CEO, said: “A key part of the future of IAMGold is our organic growth pipeline, starting with the Côté Gold Project in northern Ontario.

“The transformative impact of Côté Gold on IAMGold’s production profile and global cost structure, in addition to its long mine life in an attractive jurisdiction, establishes clear and compelling reasons for this project to proceed.

“Our current financial position supports our proposed growth plans, with over $800 million in cash on hand, access to a currently undrawn $500 million committed revolving credit facility, and expected stronger operating cash flows from our current mining operations, including anticipated contributions from Saramacca at Rosebel and steady performance from Essakane and Westwood.”

A formal decision on the construction of the Côté Gold Project will be made in conjunction with IAMGold’s partner, Sumitomo Metal Mining, given a satisfactory environment for construction to proceed with appropriate work protocols in light of COVID-19 and without risk of interruption.

IAMGold said: “The company is currently working with SMM toward a formal decision. A decision in the coming months would allow construction to commence later this year with a targeted completion date of mid-2023.”

BHP readying rollout of autonomous trucks at Eastern Ridge

BHP is looking to start the roll out of autonomous trucks at its Eastern Ridge mine site in the Pilbara of Western Australia in the next month, with the fleet of 20 Cat 793 haul trucks set to be fully converted to autonomous mode by the end of the year.

The company announced earlier this year that Eastern Ridge (also referred to as Newman East) would be the next mine to benefit from autonomous haulage. This came after a previous automation announcement related to the jointly-owned Goonyella Riverside mine, in Queensland. BHP has also agreed to acquire 41 new model Komatsu 930E-5, which are autonomous ready, for its in-development South Flank iron ore mine, but the company has not yet confirmed if it will use the autonomous capability at the site.

A BHP spokesperson confirmed the existing fleet of Cat 793s were set for automation retrofits, explaining that the roll out would occur from the end of June/early July.

Despite the restrictions in place to curb the spread of COVID-19, the spokesperson said the company was on track for full roll out completion by the end of year, as planned.

In the announcement back in February, BHP said the automation project at Eastern Ridge, which the company is currently using as its proving ground for innovation, was down to the significant safety benefits offered by the technology and its ability to complement the mine’s design, culture and existing infrastructure.

“Newman East is home to our innovation centre, so we’re already using technology there that helps us to be safer and more efficient,” Newman Operations General Manager, Marie Bourgoin, said. “Autonomous trucks were the next logical step.”

This shift will create more than 30 new permanent jobs at Newman East to run and maintain the trucks, according to Bourgoin, with the new roles tied to planning the truck routes and operating the autonomous systems from a control centre, which will initially be located at the mine.

It will also generate more than A$33 million ($23 million) in contracts for Western Australia businesses, with the work required to transition Newman to autonomous haulage including autonomous conversion kits, trailers, training content development and engineering and construction packages.

Newman East is one half of BHP’s Newman operations, which also includes Newman West, locally known as Mt Whaleback. No decision has been made to introduce autonomous trucks at Newman West, the company confirmed.

Caterpillar to help Newmont’s Boddington gold mine go autonomous

Newmont’s Boddington operation, in Australia, is to become the world’s first open-pit gold mine with an autonomous haul truck fleet after the miner’s Board of Directors unanimously approved investment in an Autonomous Haulage System (AHS) from Caterpillar.

The move, which will enhance safety and productivity and is expected to be fully operational in 2021, will also see the Boddington mine life extended, according to Newmont.

Tom Palmer, President and Chief Executive Officer, said: “Not only does Boddington continue to deliver strong performance, our investment in autonomous haul trucks will generate an internal rate of return greater than 35% with a more controlled and efficient haulage operation.

“We are also uniquely positioned in the gold sector to support effective implementation and operation of the fleet thanks to the technical capabilities and previous experience of leaders in our business. Simply put, Boddington will be a safer, more productive world-class gold mine in a top-tier jurisdiction.”

Total net investment in Boddington’s AHS will be $150 million, with efficiencies expected to extend the mine’s life by at least two years, Newmont said. The project will involve adding some new AHS-enabled Caterpillar 793Fs to the haulage fleet and retrofitting some existing 793Fs with AHS capabilities, a Newmont spokesperson confirmed. The company said it also saw additional upside potential from the replication of the AHS at other Newmont operations.

The company said: “Boddington’s autonomous Caterpillar haul trucks will feature rigorous safety controls that reduce employee exposure to potential vehicle interactions. No injuries have been recorded from AHS operations since their introduction into the mining industry.”

Newmont said it is also executing a “robust people strategy” at Boddington, providing opportunities for reskilling and redeployment of haul truck drivers to other roles supporting the AHS.

Boddington is Western Australia’s largest gold producer, delivering 709,000 oz of gold and 77 MIb (34,927 t) of copper in 2018. The mine directly employs around 2,000 people and is located 135 km southeast of Perth in Western Australia.

BHP studying autonomous haulage at Eastern Ridge, Daunia

Having previously said it was weighing up a project to automate around 500 haul trucks across its Western Australia Iron Ore and Queensland Coal sites, BHP has shed more light on its autonomous haulage plans.

The company made the ambitious admission in May 2019. It has since said it will introduce autonomous haulage at the BHP Mitsuibishi Alliance Goonyella Riverside mine, in Queensland, in a staged project that will see up to 86 Komatsu trucks converted to autonomous mode.

In its half-year results released today, BHP said of the 500 haul trucks it previously spoke of 150 are currently “under feasibility or execution” and 350 are included in its “medium-term plans”. Two projects in the former category include the Eastern Ridge mine site, in the Pilbara, which the company is currently using as its proving ground for innovation, and the 4.5 Mt/y Daunia coal mine, in Queensland, which BHP opened in 2013 and has a fleet of 16 226-t payload trucks (including Cat 793Fs).

In terms of capital expenditure, these projects were expected to cost less than $800 million, including $250 million for sites in feasibility and execution and up to $550 million included in the medium-term plans, it said.

WesTrac building Caterpillar autonomous training facility in Western Australia

Caterpillar dealer WesTrac has announced it will build a technology training facility in Collie, Western Australia, focused on providing courses in autonomous operations.

The centre will be the only Caterpillar Autonomous Training Facility in the world apart from Cat’s own testing and training ground in Arizona, USA. The facility will be developed on land owned by Bluewaters Farm Holdings in Collie’s Coolangatta Industrial Estate.

The project is supported by a grant through the Collie Futures Fund, awarded to WesTrac by the State Government’s Department of Jobs, Tourism, Science and Innovation.

The announcement was made at a ground-turning event in Collie attended by Western Australia Premier, Mark McGowan; Minister for Regional Development, Alannah MacTiernan; Collie-Preston MLA, Mick Murray; and WesTrac CEO, Jarvas Croome.

Croome said the investment includes a new fully autonomous Cat 789D off-highway truck, construction of an autonomous operations zone and training room facilities. The construction is scheduled to commence this month at the greenfield site near Collie’s Bluewaters Power Station.

Local contractor Piacentini & Son will carry out the earthworks and installation of key infrastructure, with training scheduled to commence in May.

“The initial focus will be to provide training in fit-out and maintenance requirements for the conversion and operation of existing Caterpillar haulage vehicles,” Croome said.

“Over time, we anticipate expanding the range of courses on offer to ensure the facility caters for the recognised skills of the future that will be in demand as the resource sector evolves.

“It’s an opportunity to position Collie and Western Australia as a world leader in advanced technology and skills development in automation and autonomous operations.”

McGowan said: “People will come from all over the world to utilise this facility – the first of its kind in the southern hemisphere and the second worldwide for Caterpillar.”

While WesTrac had evaluated several potential locations, Collie was the ideal centre for the training facility, according to Croome.

“The town has a long mining history and an experienced workforce with the potential to help run and develop the training facility over time,” he said.

“There’s also a vibrant community and plenty of supporting business infrastructure, plus a unique range of natural attractions and easy access to the wider South West region, which adds appeal for Australian and international training participants.”

Croome said WesTrac and Caterpillar clients across the Asia Pacific region had shown significant interest in having access to such training and strong demand was expected when the facility commenced operations.

NGEx weighs up autonomous haul trucks for Josemaría copper-gold-silver project

One of the few “construction-ready” copper-gold-silver projects yet to be funded has contemplated the use of autonomous haul trucks in its latest economic study.

The prefeasibility study for the Josemaría project in San Juan province, Argentina, showed ore would be mined using conventional open-pit methods and assumed the latest in autonomous haul truck technologies.

The PFS outlines the development of a 150,000 t/d milling operation able to produce 125,000 t/y of copper, 230,000 oz/y of gold and 790,000 oz/y of silver at a C1 cost of $1.26/Ib ($2,778/t) of copper-equivalent over a 20-year mine life.

The initial capital cost came in at $2.75 billion, with the post-tax net present value (8% discount) slightly below at $2 billion. All of these calculations used an average $3/Ib copper price.

The PFS was prepared and managed by SRK Consulting with input from Ausenco Engineering Canada, Knight Piésold, BGC Engineering, Merlin Geosciences and Gino Zandonai.

NGEx said the plan for Josemaria saw ore trucked from the open pit to a primary crusher, which crushed the material before it was sent to the process plant. The 150,000 t/d comminution circuit design considers high-pressure grind roll crushing followed by ball mill grinding. Conventional sulphide flotation would follow the comminution stage and is expected to produce a gold and silver-rich copper concentrate.

“Groundwater for the process plant would be supplied from nearby aquifers to the plant site, and power would be supplied via 250 km of power line construction to connect to the Argentine national grid,” NGEx said.

Concentrates would be trucked from the plant to the port of Caldera in Chile, approximately 380 km by road from the Josemaría plant site, requiring the construction of 57 km of new road to connect to the public highway.

NGEx CEO,  said: “The PFS shows robust economics and confirms the great potential of Josemaría. Long-term copper fundamentals are strong, and the global project pipeline is at multi-decade lows. We believe that this scarcity will lead to premium valuations for companies with construction-ready projects.

“We plan to work towards fast-tracking Josemaría towards production by starting work on a feasibility study, securing water rights, and advancing our environmental permitting plans.”
