As ore mines ramp up and come on stream, the total number of active surface machines (including trucks, excavators, shovels, loaders, graders and dozers) is forecast to rise from 141,470 in 2020 to 167,367 by 2025. This will be a CAGR of 3.4% from 2020 to 2025. The largest contributor to this growth is expected to be trucks, particularly smaller-sized trucks with shorter lifespans, used extensively in parts of Asia Pacific. Underground mining equipment is similarly expected to see a CAGR of 2.3% in this same time frame, with the number of mining trucks and loaders/LHDs in active underground mines expected to rise to 19,853 by 2025. GlobalData’s extensive mine-site research and equipment models have been used to build a complete view of mobile mining equipment populations globally for trucks, loaders, graders, dozers, excavators and shovels. This report includes informative breakdowns by each major region and key mining country, and also by major commodity.

Located in the Eastern Goldfields, the East Kundana joint venture (EKJV) project comprises three producing underground deposits, namely Raleigh, Rubicon and Hornet. Ore from the mine is treated at Northern Star’s Kanowna Belle processing facility.

Owning a 12.25% stake in the EKJV, Rand Mining said that the decision was reached due to the firing of stoping panels in the southern mining area of the mine last month.

The seismic response happened near the 6,000 to 5,949 levels of the Raleigh underground mine, with each of these levels sustaining substantial damage.

Northern Star holds a 51% stake in the EKJV while Rand Mining and Tribune Resources jointly own 49%.

In a press statement, Northern Star said: “EKJV Management has proposed a revised mining plan that would see underground mining suspended at Raleigh in April 2020.

“The life-of-mine plan previously presented to the company in October 2019 saw Raleigh production continuing to 2026 to exploit the ore reserves reported by Northern Star in August 2019.”

A detailed assessment to restart mining at Raleigh will be conducted while the operation is under care and maintenance until April.

Meanwhile, Northern Star noted that underground mining at its other deposits within EKJV are not affected by the Raleigh underground mine shutdown.

In November 2018, Northern Star Resources made binding proposals to acquire a 49% stake in the EKJV underground gold mining project.
