Newmont’s Canada mines hit wireless initiation milestone with Oricas WebGen

Newmont has continued to leverage the benefits of fully wireless initiation in its blasting process, having initiated its 500th blast using Orica’s WebGen™ system at its Canada mines.

The milestone was achieved at three of its underground mines in Canada, which are blasting with WebGen. Each site uses different mining methods, and all have achieved improved performance and safety in their overall mining processes with the implementation of innovative WebGen-enabled mining techniques, Orica says.

“The key to Newmont’s success was its ability to think differently and to take advantage of pre-charging with ‘no strings attached’,” the company added. “Eliminating the physical connections to each blasthole and the need for re-entry allowed the blasting sequence to be arranged for optimised outcomes.”

The blasting process changes help mines deliver significantly improved ore recovery and has simultaneously reduced interactions, cycle times and rework, according to Orica. WebGen wireless blasting technology is an innovation that enables process change unlike any other, by pre-charging blasts and firing blasts after access to the area is lost, it claimed.

Newmont’s WebGen journey started at the Musselwhite mine in late 2016 following Orica’s launch of the first-generation wireless initiation system, WebGen 100. The Orica technical team identified an opportunity to use the new technology and approached the Musselwhite team with a new concept, the “Temporary Rib Pillar (TRP) Avoca Mining” method.

Over the following months, workshops, detailed design reviews, risk assessments, crew meetings and signal surveys were completed and the first TRP stope was designed and ready to be blasted.

The initial stope was drilled and loaded in November and December 2016 and fired in January 2017.

Over the next year, the Musselwhite and Orica teams continued to use and refine the TRP method.

“As confidence in WebGen 100 increased, the teams explored other opportunities where wireless blast initiation could significantly improve safety and stope performance,” Orica said. “Several other wireless enabled mining methods were developed and evaluated through these collaborative efforts throughout 2017 and 2018.”

The results so far from the WebGen collaboration include a 20% reduction in mucking time, 14% improvement in production tonnes per day and 34% reduction in ore dilution.

Following the success of Musselwhite gold mine, the team from Éléonore Mine approached Orica in late 2018 to explore the possibilities of implementing the WebGen system on-site. The team conducted a two-day face-to-face workshop where the technical and operations teams from Éléonore and Orica met and conducted an in-depth review of Éléonore’s production mining operations.

The workshop ended with a commitment to complete a joint wireless blasting optimisation project, Orica said.

“A project charter was developed, which involved a detailed 10-stope evaluation across various geometries with the primary goal to improving stope recovery,” the company explained.

“Preparation started in early 2019 with detailed design sessions, signal surveys, risk assessments and crew information sessions.”

The first stope blast was loaded in February 2019 and fired in March. The project’s scope was completed by late summer and the project delivered and exceeded all the agreed performance metrics, according to Orica.

Sill pillars at Éléonore represent a challenge for both ground control and drill and blast teams.

“WebGen technology allowed us to safely and efficiently recover side-drilled stopes by greatly reducing worker exposure and stope cycle time,” Ugo Marceau, Drill & Blast Engineer at Newmont Éléonore, said.

Results from the WebGen introduction at Éléonore include an 86% increase in ore recovery, 72% reduction in stope time and 71% increase in drilling rates.

While the Éléonore project was underway, teams from Borden and Orica had already “white boarded” various wireless enhanced stoping scenarios to increase mining efficiency in Borden’s complex geometry.

“The main goals were eliminating as much lateral development and cemented rock fill as possible while maximising ore recovery,” Orica explained. “As with both Musselwhite and Éléonore, signal surveys, risk assessments and crew information sessions were completed to prepare the first stope.”

Borden’s first stope was loaded in early April and fired later that month. Once again, the outcomes from using WebGen exceeded those expected from a conventional approach, according to Orica.

Eric Fournier, Mine Engineering Supervisor at Newmont Borden, said: “Orica have been partners with us from the very beginning. The WebGen team is very professional, knowledgeable, and easy to work with. The technology is great but the people behind it make it happen. WebGen technology allows us to be a safer and a more efficient mine. It removes the need to send people around hazardous conditions that exist after a blast.”

Results from the Borden implementation include 98% actual ore recovery and 17% actual dilution.

Orica concluded: “Wireless-enhanced production mining has been expanded across these three Newmont mines. The WebGen system has proven itself as a reliable initiation system and enables drill and blast engineers to modify existing mining methods for substantial improvements in safety, productivity and cost reduction. This has been an exceptional journey together with Newmont and highlights the results that can be achieved through innovation and collaboration.”

CMIC-backed novel comminution technology hits commissioning milestone

The Canada Mining Innovation Council’s (CMIC) Conjugate Anvil Hammer Mill (CAHM) and MonoRoll platform technology project has reached a new milestone with hot commissioning of the MonoRoll at COREM’s testing facility in Quebec, Canada.

CAHM is a platform technology advancing two technologies in parallel where both designs break particles in a highly efficient thin particle bed. CAHM, according to CMIC, provides a more efficient alternative to high pressure grinding rolls and SAG mills, while the MonoRoll variant is designed for finer grinds and to replace inefficient rod and ball mills.

In a recent post, CMIC said hot commissioning of the MonoRoll at COREM’s testing facility, using some of the 300 t of ore contributed by Agnico Eagle Mines, was now complete. Although the MonoRoll is being tested using hard rock, there is also significant interest from the iron ore, cement and aggregate industries, CMIC says.

It added: “Fabrication of the CAHM machine is underway and if the optimised discrete element method modelling results hold, we are confident that the MonoRoll and the CAHM are on track to achieve the following significant benefits in ore grinding:

  • “Reduce energy consumption by an estimated 50% compared to best available technology;
  • “Eliminate grinding media;
  • “Increase ore feed reduction ratio; and
  • “Simplify the comminution circuits.”

CMIC is leading a consortium including experts in comminution, product development, engineering and testing as well as six major hard-rock mining companies guiding the effort and participating as potential first adopters. Included among the consortium is CTTI, Hatch, Glencore Canada – XPS (Expert Process Solutions), COREM, Teck, Agnico Eagle, Newmont and Kinross.

The MonoRoll technology is one of only six finalists in Impact Canada’s Crush It! Challenge. Launched in October 2018, Crush It! challenged Canadian innovators to deliver game-changing solutions for cleaner, more efficient rock processing.

CMIC said: “The MonoRoll project is the only finalist developing a novel grinding mill, and if the project wins the C$5 million ($3.9 million) Grand Prize, the funds would be used to engineer a large-scale machine to test in active mining operations.”

RUC Mining set for Newmont Tanami shaft lining and equipping contract

RUC Cementation Mining Contractors says its RUC Mining business has been awarded preferred bidder status for the shaft lining and equipping contract at Newmont’s Tanami Expansion 2 project in the Northern Territory of Australia.

DST to help Newmont go cyanide-free with CLEVR agreement

Dundee Sustainable Technologies has entered into a Technology Transfer Licensing Agreement with Newmont for the use of DST’s cyanide-free gold extraction technology, known as the CLEVR Process™.

DST has been in ongoing discussions and technology review with Newmont regarding its CLEVR gold extraction process to evaluate and quantify its applicability on projects selected by Newmont.

Following a successful test work program in the March quarter of this year, Newmont expressed its interest in the execution of such an agreement allowing Newmont to conduct laboratory CLEVR leaching tests in its technical facilities in Englewood, Colorado.

The method used by DST uses no cyanide, produces no toxic liquid or gaseous effluent, and the solid residues are inert, stable and non-acid generating, according to the company.

David Lemieux, President and CEO, said: “We are very pleased to announce this agreement with Newmont which is the culmination of much work and dialogue between our companies. Our collaboration with a global gold producer is the result of years of continuous efforts in developing an innovative and technically sound process for the industry.”

He added: “Today’s announcement is further validation of DST’s CLEVR Process as one of the leading cyanide-free alternatives for the gold industry, and it represents an important milestone in the early-stage adoption and understanding of our technology by a world leading gold company.”

As part of the agreement, DST and Newmont, agreed to:

  • A two-year, non-exclusive licence for the utilisation of CLEVR at the laboratory scale in its Colorado technical facilities with an option to renew, for an additional two-year period under the same terms;
  • Technology implementation support by DST, including all technology laboratory protocols in addition to technical training sessions to initiate and support the technology transfer and practical operations;
  • Ongoing technology support and for DST to review the laboratory test plans, execution, and results conducted by Newmont; and
  • Any process scaling-up requirements, resulting from positive applications of CLEVR, will be conducted jointly with Newmont at DST’s technical facilities in Canada and/or on-site using DST’s technology and engineering group expertise.

The objective of the agreement is to facilitate the adoption, understanding and application of CLEVR on various gold projects being, or to be, developed by Newmont. The agreement was executed on November 25, 2020.

Newmont overcomes COVID-19 challenges to complete Musselwhite gold mine work

Newmont says it has successful completed two key projects at its Musselwhite mine at Lake Opapimiskan, Ontario, Canada, with the full commissioning of the mine’s conveyor system and the material handling project.

Newmont’s President and CEO, Tom Palmer, said: “I am extremely proud of the work that has been completed by the team at Musselwhite to safely deliver these two critical projects, whilst managing through the unprecedented challenges caused by COVID-19. Musselwhite is an important part of our North America region, and with the commissioning of these two projects is positioned to contribute to Newmont’s portfolio for many years to come.”

The conveyor system and the material handling systems work in association to efficiently move material from deeper mine levels to the surface, according to Newmont. Haul distances are reduced as the ore crushed at depth will be hoisted from the underground crushers to the conveyor system and brought to the surface for processing.

Work on the $90 million materials handling project to improve the movement of ore to the mill started back in 2016.

RUC Cementation, GR Engineering plan to collaborate on Tanami Expansion work

RUC Cementation Mining Contractors and GR Engineering Services have agreed to team up as part of a plan to construct surface infrastructure, as well as complete the shaft lining and equipping for a proposed hoisting shaft at the Newmont-owned Tanami Expansion 2 project in the Northern Territory of Australia.

Today, Barry Upton (right), Managing Director of RUC Cementation Mining Contractors, and Geoff Jones (left, next to Rod Schier, Engineering Manager for GR Engineering), Managing Director of GR Engineering Services, signed this “Teaming Agreement”.

The surface infrastructure component the two plan to work on includes winders, headframe and surface conveyors.

The companies said: “Both companies have worked together to submit a competitive and technically strong offer for the works and look forward hopefully to an award in the near future.”

RUC added: “Whilst a departure from the traditional GR Engineering work scope of treatment plant construction, RUC Mining is very pleased to have GR on board as a key construction partner and values the excellence in construction that GRES bring.”

The Tanami Expansion 2 project is expected to increase the annual capacity of the processing site to 3.5 Mt/y, from 2.6 Mt/y, and extend the life of the mine beyond 2040.

Newmont aims for net zero carbon emissions by 2030

Newmont has announced what, it says, are “industry-leading climate targets” to reduce its greenhouse gas (GHG) emissions by 30%, with an ultimate goal of achieving net zero carbon emissions by 2050.

The new 2030 target builds upon Newmont’s existing GHG emissions reductions target of 16.5% over five years, concluding in 2020.

“At Newmont, we hold ourselves to high standards – from the way in which we govern our business, to how we manage relationships with our stakeholders, to our environmental stewardship and safety practices,” Tom Palmer, President and CEO of Newmont, said. “We fundamentally understand the human contribution to climate change and understand we reap what we sow. It is our responsibility to take care of the resources provided to us.

“We take these climate change commitments seriously, and make them because our relationship with the planet is absolute. We want a world that is not just sustainable, but thriving for generations to come.”

Using science-based criteria, Newmont has set climate targets for 2021-2030 for its operating sites, including a renewable energy target. The science-based criteria align with Science-Based Targets Initiative criteria and assists Newmont in developing specific emissions reduction pathways and meeting the Paris Agreement objective of being well below 2°C global temperature change, the miner says.

To achieve these aims, the company will implement a new energy and climate investment standard, to be combined with its existing investment standards including shadow carbon pricing, in order to further inform its capital investment process, it said.

“This new investment standard will ensure that the 2030 reduction targets are embedded into investment decisions for projects such as fleet vehicles, production equipment, on-site renewable power generation and energy efficiency,” the company said. “Additionally, the company will engage its partners and joint ventures in an effort to align joint venture operations targets and supply chain related emissions with Newmont’s targets.”

Mining is an energy intensive business, with 88% of Newmont’s energy used for mining and milling generated from carbon-based fuels, it said. As the company looks to reduce emissions and move to a low carbon economy, it will use a strategic approach to portfolio development, energy sourcing, fleet and equipment investment, as well as land use planning to achieve its targets.

A key part of Newmont’s accountability in reaching these targets will be reporting via The Climate-Related Financial Disclosures (TCFD) guidelines. In 2021, the company will issue its first annual TCFD report. The TCFD report will detail Newmont’s governance, strategy and portfolio resilience to a range of climate scenarios. The TCFD report will also track Newmont’s annual progress toward implementing its 2030 strategy, meeting its 2030 targets and executing emissions reduction projects across its global portfolio.
