Petratherm (ASX:PTR) is an Australian explorer with a focus on discovering world-class copper-gold and rare earth deposits. The company has several advanced drill-ready projects in South Australia's Olympic Copper-Gold Domain. The company has found rare earths hosted in clays within the Northern Gawler Craton, which is currently undergoing intensive drilling. Founded in 2004, Petratherm initially led the way in geothermal exploration technology. After divesting those interests, they returned to their roots: mineral exploration. Re-listed on the ASX in 2018, they hold onto their history of pioneering discoveries.
