Explorex Caravans

For more than 20 years, Explorex Caravans has been a trusted partner for Australia’s mining and exploration sectors, providing durable, mobile infrastructure built to withstand the harshest conditions. A pioneer in off-grid technology, Explorex is helping mining companies reduce their reliance on diesel generators with sustainable solar and battery-powered systems that ensure reliable, self-sufficient operations in remote locations.

A legacy of innovation in mining support solutions

Since its inception, Explorex Caravans has gained a reputation for providing high-quality, custom-built solutions for the mining industry. Known for its legendary steel-frame construction, Explorex units are engineered for strength and reliability. The company’s journey into off-grid solutions aligns with the broader shift in the mining sector toward sustainability.

Explorex’s off-grid technology leverages solar and battery systems to provide power for essential services such as accommodation, kitchens, crib rooms, offices and even electric toilets — effectively relegating traditional diesel-powered generators to emergency backup. As demand for sustainable practices has grown, Explorex has adapted its designs to meet the industry’s needs for reduced environmental impact and operational independence.

The move to off-grid power

The mining industry’s growing focus on sustainability, cost efficiency and emissions reduction has fuelled the demand for off-grid solutions. Diesel generators have long been the standard for powering remote mining camps, but these solutions come with significant environmental and logistical challenges, including fuel costs and transport risks.

In response, Explorex has developed an off-grid power system that integrates high-voltage DC power with solar panels and lithium batteries to provide reliable energy, eliminating the need for diesel generators as the primary power source.

Explorex Caravans General Manager David Hancock says the off-grid systems were developed in response to client demand for energy-independent solutions.

“Hamelin Gold approached us in 2022 with the idea of making their camp completely off-grid,” he said.

“We rose to the challenge, and the camp has now been running for almost two years without external power.”

Autonomous operation: powering every need

Explorex’s off-grid systems are designed to provide complete autonomy for remote operations. Weather permitting, the solar and battery system powers all necessary functions, including air-conditioning, refrigeration, security systems and office operations. Even the crib rooms with electric toilets do not require external water sources, beyond basic handwashing facilities.

The real-world performance of these systems has far exceeded expectations.

Hamelin Gold Managing Director Peter Bewick says the team can leave camp for a week with fridges, freezers and security cameras still running.

“When we return, everything is exactly as we left it, no spoiled supplies, no restocking required,” he said.

“The power reliability is phenomenal.”

Custom solutions to meet unique needs

Explorex stands out for its ability to customise off-grid solutions to suit the specific needs of each client. While its off-grid systems are based on a proven steel-framed platform, Explorex works closely with companies to adapt the units for unique operational requirements. Whether it’s integrating additional safety features, including Starlink for remote connectivity, or ensuring that systems meet specific environmental standards, Explorex offers tailored solutions for every project.

“We pride ourselves on working with clients to provide exactly what they need,” says Explorex Managing Directors Greg Ferguson.

“Every project is different, and we take the time to ensure our units are designed to meet each client’s unique specifications.”

Sustainability and cost savings: why off-grid makes sense

The environmental and financial benefits of off-grid technology are significant. By reducing reliance on diesel generators, mining companies can save on fuel and maintenance costs, as well as mitigate the risks associated with fuel transport.

“We’ve saved $60,000 in fuel costs over 18 months, and that doesn’t even account for the reduced risk of transporting fuel,” Mr Bewick said.

“Off-grid systems pay for themselves quickly, and the benefits only continue to grow.”

For mining companies looking to meet their environmental, social and governance (ESG) targets, Explorex’s solar-powered caravans offer a practical, sustainable solution. Eliminating diesel consumption not only reduces carbon emissions but also eliminates the noise and fumes generated by traditional power systems.

“The cost savings are significant, and the environmental benefits are clear,” Mr Hancock said.

“This technology helps our clients meet their sustainability goals while improving operational efficiency.”

Technology and Innovation: evolving with the industry

Explorex continues to refine its off-grid technology, working with clients to integrate the latest advancements in solar and battery technology. The company is focused on improving energy capacity while reducing the weight and footprint of its systems, ensuring that they remain adaptable and scalable as technology continues to evolve.

“As solar and battery technology improve, we’re constantly working to enhance our systems,” Mr Hancock said.

“Our goal is to increase energy capacity without adding unnecessary weight or complexity to our units. We’re committed to staying ahead of industry trends and delivering the most efficient solutions possible.”

Explorex’s commitment to innovation has also led to growing interest from industries outside of mining, such as remote infrastructure projects, emergency response operations, and agribusiness. The versatility of the off-grid system makes it a compelling solution for a wide range of applications that require reliable, sustainable power in isolated locations.

The future of off-grid mining operations

Explorex is positioning itself as a leader in the off-grid power space, with a scalable manufacturing capacity that allows them to produce up to three off-grid units per week to meet growing demand. As more mining companies seek to reduce their environmental impact and operational costs, Explorex remains focused on providing reliable, self-sustaining infrastructure that meets the challenges of remote exploration.

“The mining sector is increasingly moving toward off-grid solutions as part of a broader trend towards sustainability,” Mr Ferguson said.

“Off-grid technology is no longer just a nice-to-have, it’s becoming essential for companies that want to remain competitive and meet their environmental targets.”

A new standard for remote mining operations

Explorex Caravans has long been a leader in providing durable mobile infrastructure for the mining industry. With the introduction of its off-grid solar and battery systems, Explorex is now helping companies transition to more sustainable, cost-effective operations in remote exploration sites. The company’s dedication to innovation, customisation and sustainability ensures that it will continue to lead the way in off-grid solutions for the mining sector.
