Petratherm Ltd.'s landholdings increased to 1,489 square kilometers as it secured a second license application in South Australia, prospective for iron oxide-copper-gold-style mineralization.

The company said Dec. 12 that the geophysical features of the new license area are similar to BHP Group Ltd.'s latest discovery at Olympic Dam, approximately 160 kilometers to the southeast.

Petratherm is reviewing previous exploration results and is processing geological and geophysical data to start field work as soon as the tenement is granted.
