Rex Minerals Ltd shares have surged close to threefold after the junior explorer reported high-grade copper and gold drill results from its Hillside project in South Australia.
Managing director Steve Olsen described the discovery as "spectacular" and said the company had not yet intersected the source of the gravity anomaly, which is expected to contain the highest concentration of copper.
Rex Minerals shares had gained 19 cents, or 146.15 per cent to 32 cents by 1108 AEDT on Monday.
Hillside is located on the Yorke Peninsula in SA.
