Evolution enlists RCT and its Guidance Automation tech to transform Red Lake gold mine

Evolution Mining has selected RCT and its ControlMaster® Guidance Automation technology to help “transform” its new Red Lake mine in Ontario, Canada.

Evolution has embarked on a three-year investment strategy to restore the newly acquired Red Lake mine to a safe, highly efficient, long life and low-cost operation providing strong value for shareholders. This followed its acquisition of the operation from Newmont in November 2019 in a deal that could eventually rise to $475 million.

RCT has previously worked with Evolution Mining on transitioning its Mungari operations in Western Australia’s Goldfields region to its fully-autonomous technology solution.

To assist in the Red Lake turnaround strategy, RCT will commission its interoperable and scalable ControlMaster Guidance Automation technology to the underground loader fleet.

RCT says it is working closely with Red Lake’s leadership team to seamlessly integrate the new technology to enable greater productivity efficiencies to support Evolution Mining’s transformation strategy.

“The technology will unlock significant value for Evolution Mining by ensuring optimal machine performance, higher speed autonomous tramming, and reduced machine damage,” RCT said. “The technology will deliver faster production cycle times and reduced unplanned downtime across the loader fleet.”

The loaders will be controlled from either the surface-based ControlMaster Automation Centre or the customised underground Automation Centres designed specifically for easier transfer via the mine shaft hoist system.

This solution safeguards machine operators by relocating them away from hazards commonly found at the mine face and significantly reduces shift handover times, lowering overhead costs and resulting in greater site efficiencies, RCT said.

Kirsty Liddicoat, Red Lake General Manager, said: “We are very pleased to be partnering with RCT to introduce modern technologies to Red Lake as part of our transformation process. RCT equipment will enable higher productivity and efficiencies from our underground scoop fleet, while improving safety for our people.”

RCT’s Mining Business Development Manager, Ryan Noden, said ControlMaster is an ideal solution to help deliver the operational transformation that is aligned to Evolution Mining’s Red Lake strategy.

“The advanced features of the ControlMaster Automation technology means Red Lake will be able to quickly achieve improved production efficiencies from its loader fleet, with a greater level of safety for its operators,” he said. “Red Lake will also benefit from selecting a truly interoperable technology provider that can collaborate closely with them to realise further mobile equipment automation opportunities as further optimisation of the asset is achieved.”

Noden added: “RCT has a proud history of delivering value to the Canadian mining sector and we look forward to continually delivering to them with our cutting-edge technology backed by our dedicated in-country support team based at the company’s facility in Sudbury, Ontario.”

Evolution’s vision is to restore Red Lake to be one of Canada’s premier gold mines sustainably producing 300,000-500,000 oz/y of low-cost gold, Jake Klein, Evolution’s Executive Chairman, has said.

Canada Nickel’s Crawford mine could be low carbon nickel leader, Skarn says

Canada Nickel Company, following an assessment from metals and mining ESG research company, Skarn Associates, claims its Crawford project in Ontario, Canada, could have an industry leading low carbon footprint, lower than 99.7% of existing global nickel production.

When in operation, Crawford is expected to produce 2.05 t of carbon dioxide (CO2) per tonne of nickel-equivalent production over the life of mine, which is 93% lower than the industry average of 29 tonnes of CO2, it said.

These results are based on a study by Skarn Associates, applying data from Canada Nickel’s preliminary economic assessment (PEA), the results of which were released on May 25, 2021. This study from Ausenco estimated annual average nickel production of 34,000 t over a 25-year life of mine, use of autonomous trolley trucks and electric shovels to reduce diesel use by 40%, and optimisation of the carbon sequestration potential of the tailings and waste rock. A feasibility study on the project is expected to be completed by mid-2022.

On the Skarn study, Canada Nickel said: “Importantly, this CO2 footprint estimate does not include the carbon offset expected to be provided from the process of spontaneous mineral carbonation from the tailings and waste rock comprised largely of serpentine rock which naturally absorbs CO2 when exposed to air.”

Mark Selby, Chair & CEO of the company, said: “This study demonstrates that Canada Nickel’s Crawford project can be a world-leading large scale, low cost nickel supplier while possessing an extremely low carbon footprint. I am particularly excited that we can achieve this result even before we include the carbon offset potential from our waste rock and tailings which we expect to allow us to produce NetZero NickelTM, NetZero CobaltTM, and NetZero IronTM.

“These results reflect the mine’s low strip ratio and our ability to utilise the low carbon hydroelectricity in the region and by using trolley trucks and electric shovels to reduce the consumption of diesel fuel.”

Skarn Associates’ proprietary E0 GHG intensity metric relates to Scope 1 and 2 mine site emissions from mining and processing of ore, plus fugitive emissions. It includes emissions from integrated smelting and refining facilities, but excludes emissions from third-party smelting and refining, Canada Nickel explained.

Emission intensities are stated on a recovered nickel-equivalent basis, calculated using average 2020 metal prices. Emissions are pro-rated across all commodities produced by the mine, based on contribution to gross revenue.

New Gold heads towards New Afton’s B3 Zone

New Gold is set to soon start ore extraction activities at New Afton’s B3 Zone in British Columbia, Canada, after receiving its Mines Act Permit from the Ministry of Energy, Mines and Low Carbon Innovation.

The gold-copper mine has recently been focused on development of the B3 and C-Zones, which are likely to represent the major production sources over the next decade.

Current production is coming from the B1 and B2 Zones (Lift 1) where there are two panel caves (west and east) in operation. The B3 Cave is 160 m below and immediately to the west of Lift 1. Ore from B3 will be hauled by truck to the existing gyratory crusher, with production continuing until at least late 2024.

The C-Zone block cave zone is around 550 m below Lift 1. Development towards the C-zone is underway with production planned to commence with the first of 143 planned drawbells in the second half of 2023.

On the permit award, Renaud Adams, President & CEO of New Gold, said: “This is a significant milestone for the New Afton Mine. With the receipt of the B3 permit, ore extraction activities will begin this quarter and ramp-up over the year.

“C-Zone development continues to advance with C-Zone extraction expected to begin in the second half of 2023.”

The C-Zone permitting process was initiated during the March quarter of this year with the submission of the pre-application package to the Ministry of Energy, Mines and Low Carbon Innovation, Ministry of Environment and Climate Change Strategy and Indigenous groups.

Major Drilling’s drilling dominance aim strengthened with new Manitoba office

Major Drilling has opened a new office in Manitoba, Canada, as it looks to expand its contract drilling services and streamline its operations.

Completed at the end of 2020, the new 29,000 sq.ft (2,694 sq.m) operations head office houses an enlarged maintenance shop, parts warehouse and administrative offices. It also includes a 3.2 ha storage yard.

“We are proud of our long history in Manitoba,” Barry Zerbin, General Manager of Canadian Operations, said. “With our expanded space in Winnipeg, we can better serve our clients throughout the country and continue the specialised drilling results we are known to deliver.”

The new building stands over 8.5 m tall among developments inside the ‘CentrePort’ 8,094 ha inland port and foreign trade zone. The zone is home to North America’s largest tri-modal World Trade Center located in Rosser, part of the Winnipeg metro area, Major Drilling says.

The CentrePort campus positions Major Drilling well logistically. The geographic centre of Canada is mere kilometres from the new building where the shop, maintenance, and support staff supply crews, drills and parts across the country. The new building adds to the already strong and established framework of Major Drilling branches and shops throughout Canada including locations in Flin Flon, Sudbury, Rouyn, Timmins and Yellowknife, the company says.

The new Winnipeg location services Major Drilling’s Canadian operations with 24 offices for administration office staff, the human resources, safety and operations departments, and country managers. The maintenance team, with over a dozen employees, is housed in a 743 sq.m shop containing four full-sized bays with over 7.5 m in ceiling clearance to service all rig types in the Major Drilling fleet. The warehouse team works in a 650 sq.m facility containing inventory and spare parts. The building can also accommodate in-house training schools for additional crews coming aboard to meet client needs.

From left to right: the new Winnipeg branch location includes an 743 sq.m shop containing four full-sized bays with high ceiling clearance to service all rig types in the Major Drilling fleet; 24 offices for administration office staff; and a 650 sq.m foot facility containing inventory and spare parts

Zerbin says the expanded space allows the Winnipeg Branch to service Major Drilling’s clients in the province which include Hudbay Minerals in Flin Flon/Snow Lake; Vale in Thompson; 1911 Gold in Bissett; and Yamana Gold in Monument Bay. It also increases capacity for clients across Canada such as Foran Mining, Nighthawk Gold Corp and Sabina Gold & Silver.

Manitoba is a long-established operations area for Major Drilling. In 1998, the company completed the acquisition of the Midwest group of companies in Canada, which operated for more than 70 years of in central Canada and the Arctic. Midwest was one of the largest drilling companies in Canada with over 115 drills (80 surface, 35 underground).

The new Winnipeg office is opening just as the mining industry enters a projected upcycle in activity, according to Major Drilling.

“In 2021, Major Drilling continues its strategy of dominating specialised drilling across the globe,” the company said.

Harte Gold goes with the Watson-Marlow flow at Sugar Zone

Harte Gold’s wholly-owned Sugar Zone Mine in Ontario, Canada, is now benefiting from the adoption of Qdos and APEX peristaltic pumps from Watson-Marlow Fluid Technology Group (WMFTG).

Having deployed the pumps in two important applications, the Sugar Zone team are now enjoying far better flow rate efficiency, along with significant reductions in both maintenance requirements and downtime, according to WMFTG, with the miner subsequently looking to invest further in the company’s pumping technology.

The Sugar Zone Mine entered commercial production in 2019 and has an anticipated operating life of around 13 years at current output levels. Producing 60,000-65,000 oz/y of gold at a 800 t/d throughput rate, a mine expansion study is currently in progress to support a 1,200 t/d rate.

In the reagents room, Harte Gold operates eight diaphragm pumps on a 24/7 basis. However, issues over insufficient process efficiency, the amount of maintenance time needed to replace diaphragms and the potential for leaks prompted the company to look at alternative solutions.

Harte Gold invited WMFTG to trial its Qdos 30 chemical metering pump. For a period of one month, the mining company compared the Qdos with an existing electric diaphragm pump dosing flotation reagents such as potassium amyl xanthate (PAX).

With a flow rate for PAX of 100-300 ml/min, the Qdos 30 significantly outperformed the diaphragm pump on flow rate efficiency, according to WMFTG. Although the dosage rates were adjusted as required before and during the trial, the Qdos outputs were noticeably more consistent in comparison with the existing pump, bringing potential for process optimisation.

ReNu peristaltic pump head technology is at the core of the Qdos pump and is key to its success at Harte Gold, WMFTG says. ReNu ensures accurate and repeatable chemical dosing and, thanks to its contained design with integral leak detection, reduces wastage and eliminates any potential for operator exposure to chemicals.

In addition, Harte Gold personnel confirmed both operations and maintenance were trouble-free during the trial runs. Indeed, there were favourable reports of the colour TFT display, which shows both flow and speed, while the maintenance team was in full support of the single, no tools ReNu pump head replacement.

Such was the success of the trial that Harte Gold is now looking to gradually phase-out all eight of its existing diaphragm pumps in the reagents room over the coming few months. Although control of the first Qdos 30 on site is manual, the company will adopt 4-20 mA I/O moving forward, according to WMFTG. Harte Gold is also planning to replace diaphragm pumps with Qdos models on the water treatment side of its business.

In another area of its operations, Harte Gold has replaced an existing peristaltic pump (not Watson-Marlow) with an APEX 35 in a 24/7 application. Here, the pump transfers thickened gravity concentrate from a gold decanting tank to a shaker table. However, the company found itself replacing hoses every week in its existing peristaltic pump.

The company already had an APEX 35 in operation so thought the same model would provide a good solution for the thickened gravity concentrate. Instead of the one week hose life previously achieved, the APEX 35 with NR hose lasted for 12 weeks, reducing both maintenance and downtime in this critical application. Now, only four hoses are required per year, rather than 52, equating to a 1,200%-plus gain in maintenance intervals, the company said.

Kirkland Lake Gold boosts Macassa battery-powered fleet with Artisan Z50s

With production at the Macassa gold mine in Ontario, Canada, set to ramp up over the next three years, Kirkland Lake Gold is, once again, bulking up its fleet of battery-electric equipment.

In its just released December quarter results, the company confirmed it recently purchased five 50-t battery-powered underground haul trucks for the operation, with the first already delivered in the current quarter.

The loaders in question are Artisan Z50s, which have a 50-t payload and are equipped with AutoSwap, a patented self-swapping system for the Artisan battery pack.

Macassa is a first adopter of battery-electric equipment, testing out early protoype versions of machines and now having a large fleet of trucks and LHDs from the likes of Artisan and Epiroc.

Kirkland Lake has big plans for Macassa, with the #4 Shaft project underpinning much of the planned growth.

In the quarterly results, the company said the shaft advanced 875 ft (277 m) in the three months ending December 31, having now reached a depth of 4,240 ft. Kirkland Lake said the project, which will see the shaft sunk to a depth of 6,400 ft in one phase, was around one month ahead of schedule at the end of 2020. Project completion was targeted for late 2022.

Macassa produced 183,037 oz of gold in 2020, down from 241,297 oz in 2019, following COVID-19-related changes. The company expects the mine to ramp up over the next three years, reaching 400,000-420,000 oz in 2023 following completion of the #4 Shaft.

MineSense to expand XRF ore sorting presence at Copper Mountain mine

MineSense Technologies says the use of its ore characterisation and sorting technology is seeing improvements in both the ore from waste recovery and ore dilution at Copper Mountain Mining Corp’s namesake mine in British Columbia, Canada.

Having deployed the company’s ShovelSense solution on two shovels and a wheel loader in 2020, Copper Mountain now has plans to install ShovelSense on the two remaining shovels in 2021, along with the first trial installation of BeltSense to explore additional innovation concepts, Don Strickland, Chief Operating Officer at Copper Mountain Mining Corp, said.

Jeff More, President and CEO of MineSense Technologies, said: “Copper Mountain has been a fantastic partner to work with, initially to support us in our scale-up on hydraulic shovels, and then with rapid commercial deployment once the design was stabilised.

“We are thrilled that they installed three of our ShovelSense Systems in the space of five months in 2020 and will complete installation of their entire shovel fleet in 2021.”

The MineSense hardware and software went through a two-year evaluation process at Copper Mountain prior to the solution going commercial, Copper Mountain stated in a recent technical report.

The ShovelSense system improves orebody visibility bucket by bucket in real time during the loading process, according to the company. Trucks are then automatically diverted to the correct location, increasing value and revenue realised during the mining process. The technology also creates reductions of CO2 emissions per tonne of ore produced, consumption of processing chemicals and reagents, energy and water, while maximising metal recovery.

BeltSense, meanwhile, is used on conveyance at different points of the mine operation. It can be used sequentially and in conjunction with ShovelSense to maximise the ore concentrating impact, taking a first cut at the haul point and second further downstream, MineSense says.

Both systems leverage X-ray Fluorescence sensors to carry out the sorting process.

Perenti plants roots in USA on North America contract mining potential

Perenti Group has targeted the North America market for further contract mining growth, establishing a US office in the first half of its 2021 financial year.

The office, thought to be in Denver, Colorado, will help the company make the most of the substantial pipeline it has identified in North America.

The news came during the company’s first half results to the end of December 2020, which showed off revenue of A$1.01 billion ($799 million) and EBITDA of A$201 million.

Noting strong growth in its underground business and a contraction in its Africa surface business (most of which is tied to its AMS subsidiary), the company said it had won A$1.1 billion of new work and extensions since July 1, 2020, while its orderbook was around A$5.5 billion and its pipeline was circa-A$9.2 billion.

Within this global pipeline, A$2.1 billion was in the North America region, Perenti said. This was made up of 14 projects, three of which were at the tendering stage. Overall, 14% of the pipeline was from the US and 9% was in Canada.

The company, through its Barminco subsidiary, won its first “significant” North America contract last year when it signed on to an underground contract mining agreement at Barrick Gold’s Hemlo mine in Ontario, Canada (pictured).

In other news, the company said increased demand for its MinAnalytical mineral sample processing had been registered in the six months to the end of December, with record PhotonAssay processing recorded in December 2020.

The company also said it was “progressing alternative service offerings” during 2021.
