Why mines can no longer afford reactive operations

In an environment where every minute of lost production has a direct financial impact, operational resilience makes or breaks margin, says Warwick Bouwer, Chief Executive Officer of Jachris. Here, he shares insight into how mines must maintain continuity in the face of ongoing disruption.

Mining has always operated under pressure, but disruption has taken on a different character in recent years. More than the occasional or isolated incident, it has become constant, layered, and more often than not, predictable.

This shift is clearly visible in what is happening on site, day after day, to see this reality.

Consider the strain of shutdowns and ramp-ups on equipment as power supplies remain unstable. In terms of seasonal changes, these can shift operating conditions in ways that affect both machinery and workforce performance, and supply chains are becoming increasingly inconsistent, with the availability of parts a recurring constraint, especially in remote locations. Even skills gaps introduce daily workforce changes that are not easily resolved.

Together, these challenges create a level of operational friction that steadily undermines performance. And what makes this more complex is that disruption builds over time so that before it is even recognised, it is already entrenched.

Maintenance is a prime example. Production is prioritised over scheduled maintenance, and systems that should be serviced continue running long after the safety window closes. These may seem like small decisions made to ensure continued output, but in reality, they add up quickly until suddenly downtime dictates productivity.

The impact of getting this wrong can be felt immediately, which is why leading operations are rethinking their approach, pushing maintenance to the top of the agenda and embedding it into daily operations so that it becomes part of machine availability itself, rather than something that interrupts it.

Beyond operational pressures, another less visible, but equally critical challenge facing many mines is how their supplier ecosystems are structured and how accountability is distributed across them.

It is common to see multiple suppliers operating across similar categories, often with the intention of reducing risk, but in practice, this approach tends to dilute accountability and weaken performance at the point where it matters most. When responsibility is shared, ownership becomes unclear, and no single partner is fully accountable for outcomes. At the same time, the incentive to invest deeply in the site is reduced, resulting in lower stockholding, limited technical presence, and slower response times.

Multiple service providers working in parallel often deliver partial coverage, collectively reaching only around 70% of what is required. In contrast, a single, committed partner is far more likely to overinvest in the operation, delivering closer to 120% through deeper stockholding, stronger technical capability, and faster, more aligned response.

That difference becomes even more critical in remote mining environments where infrastructure is limited, logistics are complex, and external support is never immediate.

In these conditions, the ability to respond effectively depends entirely on what is already present on site, which is why models such as vendor-managed inventory and permanently embedded technical teams are becoming increasingly important, as they remove reliance on uncertain supply chains and ensure that maintenance is continuous, aligned to real operating conditions, and integrated into daily operations rather than delayed until failure forces intervention.

This is not about efficiency alone; it is about regaining control over variables that would otherwise sit outside the operation’s influence.

Data also plays an important role in strengthening this control, but only when it is used to drive meaningful action, because when operations can link equipment failure and fleet availability back to root causes, they begin to identify patterns that allow them to move from reactive maintenance to predictive intervention, improving both planning accuracy and operational stability over time.

Even with systems, data, and processes in place, one factor continues to shape outcomes more than any other, and that is people.

Skills shortages and workforce changes introduce a level of variability that cannot be ignored, as knowledge gaps lead to mistakes, and mistakes lead to downtime, particularly in specialised systems where technical expertise is critical. Long-term partnerships with experienced service providers help to stabilise this environment by retaining knowledge, ensuring consistency, and reducing the operational risk that comes with constant change.

Mines cannot control commodity prices, fuel costs, or geopolitical forces, but they can control how prepared they are to operate through disruption, and that preparation is not built in response to failure, but in how operations are structured from the outset.

Mining operations fail through gaps that are consistently accepted and risks that are allowed to accumulate until they begin to affect performance. The operations that outperform are not the ones that avoid disruption. They are the ones who refuse to operate alongside it.
