Epiroc says it has won a large order in Mexico from Canada-based mining services provider Dumas Contracting Ltd for underground mining equipment and related services and solutions.

Dumas, a subsidiary of STRACON Group – a leading provider of state-of-the-art underground and surface mining services throughout the Americas – is a full-service underground mining contractor. It has ordered a range of Epiroc rigs for face drilling, production drilling and rock reinforcement, as well as loaders and mine trucks for use at a silver mine in northern Mexico.

The order is valued at about SEK200 million ($19.5 million) and was booked in the March quarter of 2024.

Helena Hedblom, Epiroc’s President and CEO, said: “We have several years of successful partnership with Dumas in Canada and the United States, and we are happy to now support them in Mexico so they can provide their mining clients with the best solutions possible to strengthen safety and productivity.”

Paolo Herrera, Vice President Operations, Mexico, Dumas, said: “Building upon decades of successful partnerships, we have once again aligned with Epiroc to provide equipment solutions to one of our critical projects in Mexico as both parties were able to develop a common understanding of service delivery, which will enable Dumas to add value to our mining clients. We look forward to delivering world-class mining services that are founded in safe and productive performance.”

The ordered equipment includes Boomer 282 and Boomer S1D face drilling rigs, Boltec S and Boltec 235H rock reinforcement rigs, Simba S7 production drill rigs, Scooptram ST1030 and Scooptram ST7 loaders, and Minetruck MT2200 and Minetruck MT436B haulers.

Epiroc will also provide spare parts, drilling tools, technical service and training on site, as well as safety-enhancing digital solutions that include asset tracking.

The new order follows a smaller order from Dumas in the December quarter of 2023. Dumas then ordered Boomer 282 and Boltec 235 rigs for use at a new gold mine in Mexico.

Gowest Gold has engaged Dumas Contracting Ltd, part of STRACON SA, in a four-year contract to assist with the restart of operations at the Bradshaw gold deposit, in Timmins, Ontario.

Dumas has already begun moving equipment to the site and is rapidly ramping up the mobilisation process, with both Gowest and Dumas targeting the resumption of underground work in April.

Dumas is a leading, full-service mining contractor specialising in mine construction and development, production mining and engineering. It is the primary contractor working at numerous mines throughout the Americas, including several in northern Ontario, Gowest said.

Currently, Bradshaw contains a NI 43‐101 indicated resource estimated at 2.1 Mt grading 6.19 g/t Au for 422,000 oz of gold, and an inferred resource of 3.6 Mt grading 6.47 g/t Au for 755,000 oz of gold. Further, based on the prefeasibility study produced by Stantec on June 9, 2015, Bradshaw contains probable reserves (using a 3 g/t Au cutoff and a gold price of $1,200/oz) of 1.8 Mt grading 4.82 g/t Au for 277,000 oz of gold.

Dan Gagnon, President and Chief Executive Officer of Gowest, said: “We are extremely pleased to have Dumas, with their extensive experience and focus on safety, as our long-term partner in restarting mining activities at Bradshaw. At the same time, now that we have the significant financial support of several of our major shareholders, we are also quickly advancing on several related fronts. This includes hiring personnel, mobilising equipment, ordering consumables and other preparations to ensure Bradshaw’s success as the next new gold mine in the Timmins camp.”

The first underground work will focus on the development and production of the initial bulk sample area (East Zone), the development of ventilation infrastructure, as well as the development of a ramp to expand and access new ore zones, Gowest says.

The company is also working towards finalising an agreement for milling Bradshaw’s ore, working with several parties to determine the optimal approach for handling the gold concentrate.

Nevada Copper drafts in Dumas Mining as part of Pumpkin Hollow restart plan

Nevada Copper, in providing an update on restart and operational activities for its Pumpkin Hollow underground copper mine in Nevada, USA, has confirmed the appointment of Dumas Mining as its Capital Projects Construction contractor.

The company is currently targeting a mill restart in the September quarter with a quick ramp up to nameplate capacity by the end of 2023.

Back in June 2022, an unidentified weak rock structure was encountered in the main ramp to the East South Zone at the undeground mine. This, Nevada Copper says, restricted access to the company’s planned East South stoping zones. In response to this event, the company took steps to curtail operating activities while developing plans to address this issue.

In the latest update, Nevada Copper said it had a clear line of sight to full-scale production with a “simple and low-risk pathway to full-scale production” established.

Randy Buffington, President & CEO of Nevada Copper, stated: “Our Pumpkin Hollow team is focused on advancing the restart project quickly and safely. We are building on the momentum of the recent achievements by the underground crews as they have progressed through the dike structure and are advancing into the EN Zone in anticipation of the underground development contractor arriving on site and commencing development. The technical and leadership teams are in place and committed to executing this restart plan. We are targeting a mill restart in the third (September) quarter with a quick ramp up to nameplate capacity by the end of 2023.”

Development into the EN Zone has demonstrated that rock quality is consistent with its geotechnical model, which predicted competent ground within the EN Zone, and development is progressing at full round lengths and standard ground support, Nevada Copper says.

The company has awarded a contract for completion of capital projects to debottleneck restart of development and underground operations. This is where Dumas is involved with Nevada Copper signing a $12 million construction contract to complete critical capital projects including the coarse ore bin and installation of an underground jaw crusher, permanent dewatering system, vent shaft stripping and surface fans. Dumas, part of Stracon, is a full-service underground mining contractor providing mine construction, development, production mining, mine services and engineering early-stage projects through well-established operating mines throughout the Americas.

Nevada Copper says its operations team, meanwhile, continues to make rapid progress on all underground activities including mine development, hoisting, stope preparation and underground projects. It has completed the bid process for the development mining contractor and is in the final stages of negotiations for a unit rate contract with an “internationally recognised major mining services contractor”, it said.

Key components of the development contract include 72,000 ft (21,946 m) of lateral capital development over a 24-month contract period; delivery of full development stopes by the September quarter of 2023 to provide sufficient faces and stopes to restart and maintain nameplate milling operations (approximately 5,000 t/d); and Nevada Copper’s operating team will perform all stope mining starting in the September quarter.
