A like-for-like Sandvik Bolting Head (SBH) upgrade at the New Afton mine, in British Columbia, Canada, is delivering a significant productivity boost at the New Gold-owned operation, according to Sandvik Mining and Rock Solutions.

Launched over a decade ago, New Afton’s now ageing Sandvik DS300 drill rigs are being given a new lease of life, thanks to an upgrade that sees a current generation bolting head fitted in a like-for-like replacement. Not only is maintenance more straightforward and spare parts easier to source, the new bolting head is delivering a remarkable productivity increase – of 25% – Sandvik claims. In fact, so successful has the mine’s 2021 upgrade been that New Gold has recently confirmed a second of its Sandvik DS300 drill rigs will be given the treatment.

Bolting rigs are used to stabilise hanging and side walls in underground mine applications.

“The upgraded SBH bolting head fitted to the Sandvik DS300s is the business end of the drill and features the latest RD300 series rock drill,” Francois Nell, Sandvik Mining and Rock Solutions’ Head of Rebuilds and Upgrades, says. “This makes it perfect for rock reinforcement in underground mines with small-and-medium cross sections. Different bolt type and length configurations are available, providing an extensive bolt selection, while a full bolt carousel ensures the DS300 is capable of installing up to 15 bolts, ranging from 1.6-3 m in length. Bolt types include cement grouted, resin grouted, anchor point and friction bolts.”

There are several benefits of adding new technology to ageing drills, according to Nell.

“The new SBH is already proven in the field and gives an instant performance boost, thanks to the RD314’s much improved penetration rates,” he explained. “Added to that is the convenience of being able to source readily available current parts more easily, as well as increasing mine’s parts commonality across more drills.

“Also, the new SBH doesn’t put the rest of the D300 under additional strain; in fact, due to the lighter RD314 drifter compared to the drill it replaces, machine strain is, if anything, reduced.”

The SBH upgrade itself is straightforward, coming in kit form, and can be conducted by a mine’s in-house technical teams using the instruction manual the SBH comes with, according to Sandvik. Taking at most a couple of shifts to complete, customer feedback regarding the installation process has been universally positive, the OEM says.

With several hundreds of Sandvik’s Lyon, France-built D300s still working around the world, Sandvik says it expects that this SBH upgrade will be as popular with other mines as it is at New Afton.

Epiroc and Rokion battery-electric machines reduce costs at Evolution’s Red Lake ops

Evolution Mining’s efforts to achieve net zero emissions by 2050 are already being witnessed at its Red Lake Operation (RLO) in Canada, where the company is pursuing fleet replacement and energy efficiency gains through deepening its partnerships with Epiroc and Rokion.

The pacts with the two battery-electric vehicle (BEV) service providers also extend to operational changes Evolution is making via fan timers for underground ventilation at RLO.

In partnership with Epiroc, Red Lake has taken the opportunity to leverage its offering of conversion kits to transform diesel-powered loaders easily and seamlessly to battery-electric driven operation, it said. RLO has ordered two of the converted diesel-powered Scooptram ST1030 machines for deployment underground with the first one delivered at the start of December 2021. The site has also ordered two Scooptram ST14 battery-electric loaders that are designed based on the diesel ST14 version, which are scheduled for delivery in 2022. This order was announced last year by Epiroc.

The Red Lake team has also purchased three Rokion electric light vehicles – two R100s and an R400. They have been risk assessed in the field, have dedicated charge stations and are capable of online data capture and storage, the company said.

Rokion says 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. The R400 platform, meanwhile, is able to accommodate three passengers in a utility vehicle setup or up to 12 in a passenger crew variant.

“The electric fleet brings the opportunity to save on maintenance, cooling and ventilation costs with reducing expenditures related to diesel and power usage,” Evolution Mining says.

“This cost saving and energy efficiency has similarly been seen in the recent changes to the underground ventilation fan timers, which are vital in clearing the drives, post blasting of headings. After assessing the timer programming, the functionality of the fan timer switch was altered so that operators can run them when needed rather than running automatically at irrelevant times.”

BQE Water has entered into an Operating Services Agreement with Minto Metals Corp to provide plant operations services for an existing water treatment plant at Minto Mine, some 240 km northwest of Whitehorse, Yukon, through to 2024.

Under the agreement, BQE Water will be responsible for clean water production at the Canadian mine where the final effluent must meet stringent requirements not only for metals but ammonia, nitrite and nitrate to protect the aquatic life in the receiving environment. Included in the operations services provided by BQE Water will be on-site technical supervision, coordination with Minto’s environmental and metallurgical team to maximise the volume of water discharged into the environment, operator training, and on-site and off-site engineering support.

BQE Water’s compensation will be composed of a base monthly fee and a supplemental fee for the volume of water treated that meets discharge specifications. It is estimated the plant will treat and discharge 400,000 cu.m of mine water for the remainder of the year and approximately 750,000-1,000,000 cu.m of mine water in each subsequent year of the current contract.

“We are highly appreciative of the responsiveness and technical proficiency provided by BQE Water to address the concerns we had with our water treatment plant,” Loralee Johnstone, the VP of Environment and Social Governance for the mine, said. “The transition to their operations has been systematic and transparent, with the resulting operational work surpassing our expectations.”

David Kratochvil, BQE Water’s President & CEO added: “We value the opportunity to help Minto achieve its environmental and social governance goals. We also look forward to collaborating with the Selkirk First Nation to achieve sustainable and transparent water management at the mine.”

As part of its role at Minto, BQE Water has engaged in discussions with the mine and the Selkirk First Nation about creating an active role for the local community to participate in clean water production at the site to ensure the continued protection of land and water for countless generations in the future.

The Minto mine has been in operation since 2007 with underground mining commencing in 2014. The current mine operations are based on underground mining, a process plant to produce high-grade copper, gold and silver concentrate and all supporting infrastructure associated with a remote location in Yukon.

Teck Resources has announced an agreement to deploy two electric tug boats at the Neptune Terminal in Vancouver, British Columbia, in support of Teck’s climate goals.

This marks the first electric tugs operating in Canada as a full tugboat package for harbour assist and tug services, according to Teck.

Under the agreement, SAAM will furnish two ElectRA 2300 SX tugs commencing operation during the second half of 2023, which are expected to eliminate over 2,400 t/y of greenhouse gas emissions. In addition to emissions reductions, using electric tugs will also reduce underwater noise, benefitting marine life in the harbour.

“Working with SAAM Towage to further reduce the greenhouse gas emissions associated with transportation of our products is another step forward in achieving our climate goals and contributing to global climate action,” Jonathan Price, CEO of Teck, said. “Collaborating with transportation providers to develop green transportation corridors is part of our climate action strategy and supports our goal of net zero emissions by 2050.”

Sander Bikkers, President, SAAM Towage Canada, added: “With Teck and Neptune Terminals, SAAM Towage has found value aligned partners who want to drive sustainable environmental change through innovation. This partnership is based on a shared commitment to do our part to address the global challenge of climate change by reducing our carbon footprint.”

The ElectRA Tugs are designed by Vancouver-based Robert Allan Ltd and will be built at Sanmar Shipyards in Turkey.

Neptune is owned by Canpotex Bulk Terminals Limited, a Canpotex affiliate, and Teck Coal Partnership, a subsidiary of Teck Resources.

This announcement builds on Teck’s progress to work with partners to reduce emissions across its supply chain and achieve a 40% reduction in shipping emission intensity by 2030.

Teck previously announced an agreement with Oldendorff Carriers to employ energy-efficient bulk carriers for shipments of Teck steelmaking coal from the Port of Vancouver, reducing 45,000 t/y of CO2, equivalent to removing nearly 10,000 passenger vehicles from the road, according to the company.

Teck has also announced a pilot of a fully electric on-highway transport truck to haul copper concentrate between Teck’s Highland Valley Copper Operations in south-central BC and a rail loading facility in Ashcroft, BC.

Teck’s climate action strategy also includes goals to reduce carbon intensity across operations by 33% by 2030 and be a net-zero operator by 2050.

Normet to supply battery-electric utility vehicle fleet to BHPs Jansen mine

Normet Canada says it has been awarded a contract from BHP to deliver a large fleet of multi-use battery-electric vehicles (BEV) to the Jansen potash project in Saskatchewan, Canada.

The delivery period of the fleet is expected to commence in the March quarter 2023 and extends to 2024.

The Normet fleet order follows on from Sandvik Mining and Rock Solutions being awarded a contract by BHP to deliver 10 underground battery-electric loaders along with 1 electric tethered loader for use at Jansen.

BHP aims to develop the underground mining equipment and automation solutions with a focus on sustainability, with emissions reduction, improved productivity and advanced health and welfare of employees being key inputs to the mining company’s decision to adopt BEV technology.

With the mine’s pursuit of electrification of mobile equipment and technology that mitigates natural gas emission, Jansen is expected to emit about half the average CO2 per tonne of product compared with the average Saskatchewan potash mine, according to BHP.

The Jansen project has the potential to be the largest potash-producing mine in the world and is expected to operate for up to 100 years, providing a rich source of potassium for soil fertilisation purposes and hence supporting food production, BHP says. Start of the production is targeted for 2026.

Redpath continues mechanised sinking evolution with S20+ deployment at Odyssey

Redpath is continuing its focus on mechanised shaft sinking operations, with the latest example being the planned use of the hydraulic shaft mucker S20+ at the Canadian Malartic Partnership’s (CMP) Odyssey gold project in Quebec, Canada.

Redpath Canada was recently contracted by the CMP to sink a 6.5-m diameter, 1,800-m deep concrete lined shaft at Odyssey, a project that has the potential to become one of Canada’s largest and most technologically advanced underground gold mines.

CMP, which is 50:50 owned by Yamana Gold Inc and Agnico Eagle Ltd, previously laid out plans to extract 19,000 t of ore at an estimated grade of about 2.75 g/t gold and roughly 5,000 t/d of waste rock during peak operations at Odyssey. The ore will be processed at the operation’s existing plant, which will eventually be adapted to the future mine’s needs including shifting from 57,000 t/d to 20,000 t/d. The ore will be hauled to surface using Blair production hoists with use of both shaft bottom and mid-shaft ore handling systems.

The sinking concept at Odyssey includes the use of the S20+, which was built by Redpath Deilmann in Germany. A previous iteration of this machine, the S20, was used with success on four shaft projects in both soft rock – with an integrated tool package – and hard rock.

The S20+ offers similar capacity/productivity to a North American pneumatic telescopic boom mucker but with a much easier learning curve for operators, according to Kevin Melong, Vice President – Shafts and Technical Services, at Redpath Canada.

Unlike the RD S100, which can move independently of the galloway within the shaft via a telescopic boom, the S20+ is connected to the galloway, requiring the lowering of the galloway to move the mucker into position for mucking.

Melong added: “The S20+ does present some potential for concurrent mucking when in and around the shaft station construction/excavation, but, in general, does not act independent of the stage as in the S100 design.”

Fitted with a bucket as standard, the S20+ offers a maximum digging depth of 7.96 m and a bucket volume of 560 litres. It also offers good flexibility, with the bucket capable of six rotations per minute.

Alongside the S20+ and the aforementioned S100, Redpath has been mechanising the shaft sinking process in mining through the use of large-diameter raiseboring equipment and operation of Herrenknecht’s Shaft Boring Roadheader (in soft-to-medium rock). The company is also working with Herrenknecht on the development of the Shaft Boring Cutterhead, a machine developed for medium-to-hard rock applications up to 250 MPa UCS.

CIMIC Group’s mineral processing company, Sedgman, has been awarded an engineering, procurement and construction (EPC) contract to deliver services for Artemis Gold at the Blackwater gold project in British Columbia, Canada.

The EPC contract, which supersedes the temporary interim service agreement announced on May 2, 2022, will generate revenue for Sedgman of C$318 million ($245 million).

Sedgman will design and construct the processing and non-processing infrastructure for a 6 Mt/y carbon-in-leach gold plant at the project.

Even before this announcement, Sedgman had made good headway on the project, executing an agreement with Metso Outotec to secure supply and delivery of crushing and grinding equipment for the processing plant.

The project schedule as laid out by Artemis supporting the EPC contract with Sedgman includes the following assumptions:

  • Receipt of the BC Mines Act and related permits in the Fall of 2022;
  • Construction mobilisation and major works preparations commence in the March quarter of 2023 with process plant bulk earthworks scheduled to be completed prior to the start of major works;
  • Commissioning activities of the process facility to commence in the firts half of 2024; and
  • First gold pour expected in the September quarter of 2024.

CIMIC Group Executive Chairman, Juan Santamaria, said: “Sedgman and Artemis have already commenced initial design and procurement work at the project, helping Artemis to unlock the value of this key gold project and work towards its first gold pour in 2024.”

Sedgman Managing Director, Grant Fraser, said: “We are pleased to be working with Artemis Gold on this exciting project and look forward to continuing our strong working relationship to ensure successful outcomes for both Sedgman and Artemis.”

Work is expected to be completed in the September quarter of 2024.

Artemis has said previously that Stage 1 development at Blackwater should lead to the building of a 6-9 Mt/y operation (6 Mt/y in years 1-4 and 9 Mt/y in year 5) able to produce around 312,000 oz/y of gold.
