Highfield Resources Ltd is an Australia-based, ASX-listed mineral development company focused on potash in northern Spain. Through its Spanish subsidiary Geoalcali S.L., the company is advancing the Muga Potash Project, located across Navarra and Aragón, to produce muriate of potash (potassium chloride) for fertilizer markets.
Highfield also holds the nearby Pintanos and Sierra del Perdón potash projects. Muga is planned as a conventional underground operation mining shallow sylvinite, with potential salt by-products. The company’s strategy leverages proximity to European agricultural and industrial customers and established logistics to supply regional potash demand.
