Mine closure was once treated mainly as the final stage of a mining operation. Today, that approach is becoming harder to justify. Closure can involve major rehabilitation work, long-term environmental monitoring, social transition, water management and changes to existing...

Mining equipment sits at the centre of production, and when a critical machine stops, the cost can extend far beyond the repair itself. A failed haul truck can reduce material movement, while a problem with a crusher, mill or...

A cut off grade may look like a simple technical boundary in mine planning, but it can influence much more than whether material is classified as ore or waste. It can determine how much material reaches the processing plant,...

When most people think about mining, they picture open pits, underground tunnels, heavy machinery and large volumes of rock being moved from one place to another. That is how most mines have traditionally operated. But there is another approach...

Coal remains one of the world's largest sources of energy, but the market around it is changing. Global coal demand reached about 8.85 billion tonnes in 2025, only slightly above the previous year, while the International Energy Agency expects...

Mining is built around production. A deposit is explored, developed and mined until the remaining ore is no longer economic to extract. At that point, attention turns to closure, rehabilitation and the long-term management of the site. But the...

Mining has always depended on finding deposits where the value of the ore can justify the cost of extraction. That balance is becoming harder to maintain. Many companies are now dealing with deposits that are deeper, lower grade, more...
