Equipment and service provider Sandvik Mining has unveiled a new multi-functional surface and underground (NSU) core barrel system for core drilling.

The newly developed system has interchangeable components including standard and pump-in applications, capable of increasing productivity for miners. The innovative design offers cost-efficient solutions by reducing networking capital and spare parts inventory, ensuring safer operations.

“The newly patented iQ-FCV valve provides and maintains a constant alert through sustained high water pressure, assuring the operator that the inner tube assembly has positively latched into the core barrel. “This eliminates mislatches and ensures that valuable time is not lost,” says Sandvik mining core drilling product line manager Chris Daws.

“For better water efficiency, the iQ Valve has been designed to always retain the volume of water in the drill string even in broken ground or dry holes, which is an important benefit in core drilling,” he adds.

The NSU system features automatic latch-locking and latches for safety and a knuckle joint for ease of handling. The core drilling unit doesn’t require cable eyes or cable splicing, making it easier for maintenance operators to repair on site.

“The Sandvik NSU and forthcoming H surface and underground (HSU) core barrel systems share the majority of components used in the core barrel head assembly,” says Daws.

“With the interchangeable design for both systems, the NSU core barrel head assembly can be converted into an HSU core barrel head assembly, and vice versa. This will significantly reduce parts and spare parts inventory.

“The new core barrel system is designed for both standard and pump-in applications, which means there is no longer a need to keep different coring tool systems on the shelf. It also reduces the net working capital for the owner,” he adds.

Sandvik plans to launch the HSU system later this year.

Codelco partners with Microsoft to extend digitisation

Codelco, the world’s largest copper producer, has struck a deal with Microsoft to promote digitisation and automation at its copper mines across Chile

Chile's Codelco, the world's largest copper producer, has announced a deal with tech giant Microsoft to fast-track the digitisation of its sprawling mining operations, helping it extend automation and improve analytics.


The joint project with Microsoft will beef up the company's capacity to make its production processes more efficient and promote "sustainability" within its operations, Codelco said in a statement.

Codelco, like many Chilean miners, has fought in recent years to adopt new technologies to boost efficiency and keep down costs at its aging deposits, many of which suffer from declining ore grades.

"We are promoting profound changes so that different areas operate in a completely remote and automated way, reducing risks, improving productivity, safety and reliability of our operation," said company executive Alvaro Garcia.

Mining companies worldwide are pushing forward with plans to operate mines remotely, reducing the risk of accidents and boosting efficiency.


Codelco’s move towards automation however has led to confrontations with unions, who see it as a threat to their livelihoods. The company said the project with Microsoft will include a training component for the its workers.

The state-run miner has recently ramped up its use of technology to ensure its copper is 100% traceable, a vital step in reducing its carbon footprint and boosting sustainability within its operations.



Codelco’s CEO Octavio Araneda said that tracing copper through its mines would help the company more precisely measure progress on its social and environmental goals while providing proof to increasingly demanding customers of those efforts.

“We can now say that 100% of our products are traced…which will allow us to have a very strong transparency regarding our resource use footprint,” Araneda said.


The announcement comes amid a broader push by the company to reduce water consumption, recycle industrial waste and scale back carbon dioxide emissions by 2030.

Codelco said in a webinar that the tool it has developed to assure traceability will help assure those sustainability targets are met.

Soaring demand for electric vehicles, a key component in the global fight against climate change, has increased attention on the carbon footprint and sustainability of inputs such as copper, cobalt and lithium.
