Metso Outotec to engineer SAF solution for MGX’s silicon project

MGX Minerals Inc has announced the engagement of global mining equipment supplier Metso Outotec for its British Columbia silicon project.

The OEM has been tasked with providing design, equipment and mechanical engineering for the processing of high-grade silica from the company’s wholly-owned Gibraltar silica deposit into silicon metal 3303# grade.

The primary piece of processing equipment related to the agreement is a submerged arc furnace (SAF). This electric arc furnace generates heat up to 1,600°C sufficient to melt the quartzite. The liquid metal is then tapped and poured into bricks and rough crushed into 3-4 in (76-102 mm) pieces for shipment.

Recent metallurgical testing on a 1 t sample from the company’s Gibraltar silica deposit, 95 km northeast of Cranbrook, British Columbia, has indicated that the material is chemically suitable as medium-quality feedstock for metallurgical-grade silicon.

MGX says the demand for silicon metal continues to grow and recent supply chain bottlenecks have limited overall supply, creating an opportunity for the distribution of silicon in Asia from North America.

Taseko Mines starts commercial construction move at Florence ISR copper project

Taseko Mines, having just completed a $400 million bond refinancing and fundraising program, is moving forward with developing a commercial operation at its Florence in-situ recovery (ISR) copper project in Arizona, USA.

Capital requirements for the commercial production facility at Florence, which followed an ISR pilot project, are estimated at $230 million.

Pending final regulatory approvals and financing, Taseko has previously stated it could start construction of the commercial operation this year, with first production in late 2022.

Stuart McDonald, President of Taseko, said: “With the majority of the required funding for our Florence Copper project now in hand, we are moving forward with final design engineering of the commercial production facility as well as procurement of certain critical components.”

McDonald said the company is continuing to advance discussions with potential joint venture partners at Florence, but its strong cash balance and improved Gibraltar mine cash flows from copper prices currently over $3.70/Ib ($8,159/t) means it has “numerous options available” to obtain the remaining funding.

Russell Hallbauer, CEO of Taseko, added on Florence: “Florence is one of the least capital-intensive copper production facilities in the world and, when fully ramped up, will produce 40,000 t of high-quality cathode copper annually for the US domestic market.

“It is a green project, with carbon emissions and water and energy consumption all dramatically lower than a conventional mine, and, with C1 operating costs of $0.90/Ib of copper, it will also be in the lowest quartile of the global cost curve.”

Taseko Mines’ Gibraltar operation honoured at BC Mine Reclamation Awards

Taseko Mines’s Gibraltar copper-molybdenum operation has been awarded the prestigious Jake McDonald Annual Award for Metal Mine Reclamation from the British Columbia Technical and Research Committee on Reclamation (TRCR).

TRCR’s annual BC Mine Reclamation Awards, which recognises outstanding achievement in mine reclamation in British Columbia, was held on September 23, 2020.

The aim of Gibraltar’s reclamation research program is continual improvement by identifying and introducing leading-edge ideas within the field of environmental science in mine reclamation, it says. With this goal in mind, projects at Gibraltar include:

  • Sampling of salmon from the Fraser River in partnerships with the Xatśūll First Nations and the North Shuswap Tribal Council to provide information to local Indigenous communities regarding the safety of consuming salmon captured at traditional fishing sites;
  • Studying and using innovative technologies to determine how reclamation activities promote the development and recovery of biological communities; and
  • Supporting BCIT, SFU, and Mitacs master’s students in a trial research program to expedite the development of soil microbial crust, specifically at the tailings storage facility.

Stuart McDonald, President of Taseko, said: “The Jake McDonald Award is the top mine reclamation award in British Columbia, a province that has a large mining industry. This achievement reflects the hard work of many talented people and we are honoured to have been chosen as this year’s recipient. The award adds to our track record of achievement which includes other recognition awards for employee safety and community service.”

Russell Hallbauer, CEO and Director of Taseko, added: “Gibraltar has been operating for nearly 50 years, generating opportunity for people and economic benefit for communities in the Cariboo. The efforts of our Gibraltar employees continue to be rewarded by achievements like this high-profile award. It is gratifying to see their talent and ingenuity being recognised at the highest levels. Gibraltar is proof of mining sustainability in action.

“We would specifically like to acknowledge the local Xatśūll First Nations and the North Shuswap Tribal Council Fisheries Department for their partnership and traditional knowledge in the annual Fraser River salmon sampling program. As well as a thank you to the Xatśūll First Nations reclamation crew, whose participation has contributed to the success of Gibraltar’s reclamation program.”

Xatśūll First Nations Chief, Sheri Sellars, said: “I am proud of the work Xatśūll First Nation community members have done in partnership with Taseko-Gibraltar. The fish sampling program and the reclamation work have been award-winning successes. Our members have also benefitted from employment opportunities and educational initiatives which stem from our relationship with Gibraltar.”

Taseko, the 75% owner of Gibraltar, restarted the operation in 2004. It is the second largest open-pit copper mine in Canada and the largest employer in the Cariboo region, according to the company.
