In this episode, Stephen and Ewan are joined by Jimmy, a lifelong West Coast coal mining expert, to explore the surprising connections between geology, mining, soil health, and modern agriculture.

What begins as a conversation about coal quickly expands into the history of New Zealand's geology, the science behind different coal types, mine rehabilitation, and how mining by-products are helping improve soil function and farm productivity.

Drawing on decades of experience in the mining industry, Jimmy shares insights into how coal is formed, processed, and used far beyond energy production, while also challenging common perceptions around environmental impact, land restoration, and the future of New Zealand's mineral resources.

Through the EFA lens, this episode examines how overlooked natural resources, practical problem-solving, and independent thinking can create opportunities for both farming and industry.

We discuss:
• How coal is formed and why different coal types have different uses
• Mine rehabilitation and restoring land back to productive use
• The surprising role of coal by-products in improving soil health
• Clean coal, energy efficiency, and common misconceptions about mining
• Why soluble silica and coal humates are becoming valuable farm inputs
• The future of New Zealand's mining industry and primary sector
• What farming and mining can learn from each other
