Canadian miner Timmins Gold has commenced drifting into the underground veins parallel to the south wall of its San Francisco gold mine—a unique pilot phase designed to test the mining and processing of the underground ore.

In preparation for full scale mining, the pilot phase, which will involve drifting into the south wall to access the veins in order to extract 14,000 tons of ore, will allow Timmins to test ground conditions, mining costs, grade and metallurgical recover of the underground ore. In addition, it will provide the company efficient platforms to further underground infill and exploration drilling.

To process ore recovered from the pilot phase, Timmins Will use selective fine crushing and heap leaching. The pilot phase is expected to take three to four months to complete.

In a press release, the Canadian junior miner said: “… previous drilling had delineated three mineralized veins near the south wall of the San Francisco pit, which averaged approximately 4 meters in width, with grades ranging between 2.5 and 5.0 g/t gold. These veins are located within 50 to 100 meters of the current south pit wall, dipping to the N-NE varying between 30 - 60 degrees. Veins extending along 300 meters of strike and 200 meters of dip have been delineated to date.”

Situated in the north central portion of Sonora, Mexico, the San Francisco mine is an open pit heap leach operation with a mineral reserve of 1.6 million ounces of gold.

Based in Vancouver, Canada, Timmins Gold is a Mexican-focused intermediate gold company with a portfolio of high-quality production and development assets all based in Mexico.

BHP, Rio Tinto & Vale launch 'Charge On' Innovation Challenge - a competition for tech innovators to reduce truck emissions via electrification

Mining giants BHP, Vale and Rio Tinto have launched the 'Charge On' Innovation Challenge to solve one of the biggest challenges the industry faces today - decarbonising mining operations.

'Charge On' Innovation Challenge

In partnership with Austmine, Australia's leading mining equipment, technology and services industry association, founding patrons BHP, Vale and Rio Tinto have launched the competition to encourage technology innovators to develop new concepts for large-scale haul truck electrification systems. The main goal is cutting emissions from surface mining operations.

“The mining industry needs to be at the forefront of tackling the climate challenge. The Charge On Innovation Challenge is a great example of the current collaborative work being done by the mining industry and mobile equipment manufacturers to decarbonise mining fleets,” the trio said in a media statement.

“In addition to providing a zero-carbon energy source, the conversion of mobile mining equipment to battery-electric can potentially unlock value, as electric motors have fewer moving parts when compared to standard equipment.”

A number of non-traditional mining sector vendors are actively developing technologies that can assist in mine electrification. By submitting a Challenge to the market, the Patrons of Charge On expect to:

  • Demonstrate there is an emerging market for charging solutions in mining
  • Accelerate commercialization of solutions
  • Indicate to suppliers, the mining industry seeks interoperable solutions
  • Maintain multiple actors and competition in the supply chain
  • Integrate innovations from other sectors into the mining sector

"We expect some solutions identified in the Challenge could provide propulsion to existing diesel-electric trucks. This may present a pathway to early implementation for dynamic charging solutions," the trio said.

Paris Agreement

Found patrons BHP, Vale and Rio Tinto are pledging their commitment to fighting climate change:

"The mining industry has an important role to reduce emissions and do our part to achieve the Paris Agreement goals to limit the impacts of climate change."

The Charge On Innovation Challenge asks vendors to present interoperable solutions that can safely deliver electricity to large battery-electric off-road haul trucks in a way that maintains or improves current productivity levels. Specifically, mechanisms capable of delivering in the order of 400kWh of electricity to each truck within a haul cycle (ie load, travel, dump, return, queue). The delivered electricity is to charge a battery, and if applicable directly propel the truck.

Austmine CEO Christine Gibbs Stewart commented: “We expect the Challenge will attract companies from a broad range of sectors including mining, automotive, aerospace, agriculture, and defence to deliver selected charging concepts to create a standard product that can interface with all trucks."

More information about the challenge will be released on May 18.

Electrification

The competition echoes growing efforts being made across the industry to tackle emmissions and promote electrification. In march this year, the Electric Mine Consortium was launched. It's founding members include Gold Fields, Dassualt Systemes and Sandvik who pledged their commitment to decarbonising mining operations.
