Petratherm Limited announced that the drilling contractor, MJ Drilling, has mobilised to site at its Mabel Creek Project Area, 50 kilometres NE of Coober Pedy (SA). Drilling of the first hole is likely to start on Wednesday and will be testing the Area 2 gravity/magnetic anomaly. The drill program will test 4 high priority gravity targets and summaries of these targets are presented in the Company's 30/01/20 & 10/02/2020 ASX releases. The Mabel Creek Ridge is considered prospective for large Olympic Dam Style Copper-Gold (IOCG) mineralised systems and related, magnetite skarn copper and high value rare-earths. Drilling will involve rotary mud drilling through the younger cover sediment to the top of the prospective crystalline basement rock and then switch to diamond coring. Each hole is likely to be between 300 metres and 400 metres deep to adequately test each target and will likely take 7 to 10 days to complete.
