Critical Mineral Discovery in Northern England

In response to the UK government’s Critical Minerals Strategy, HolmesCo has completed a comprehensive geochemical survey targeting minerals essential for the clean energy transition.

Our field teams collected soil samples from 20 sites spanning County Durham, Northumberland, Cumbria, and North Yorkshire. Each sample was analysed for enrichment in 20 critical minerals including lithium, cobalt, tungsten, niobium, and rare earth elements.

Using rigorous statistical testing at the industry-standard significance level (p < 0.05), we identified statistically significant enrichment for three critical minerals at one site near Alston, Cumbria.

“With global demand for critical minerals surging, this is a strategically important discovery. Three separate minerals showing significant enrichment at the same location strongly suggests a genuine mineralization event — right here in the North Pennines.”

— Dr G. Holmes, Chief Scientific Officer, HolmesCo

HolmesCo recommends immediate follow-up drilling at the Alston site and has applied for an exploration licence under the Crown Estate’s critical minerals framework.
