The high-priority targets were discovered through a moving loop electromagnetic (MLEM) survey.
Both EM anomalies are coincident with magnetic anomalies and interpreted to be bedrock conductors with potential to represent nickel-copper sulphide mineralisation
Notably, the larger conductor target has a strike length of over 500 metres.
St George’s executive chairman John Prineas said: “Initial results from the EM survey at the unexplored Fish Hook Prospect are extremely encouraging with new conductors identified in a prospective geological setting.
“This is a great start to the 2020 field season and we are excited at the potential for more exploration success as the work programmes progress.
“Drill hole MAD177 is a reminder of the remarkable mineralisation at the Cathedrals Belt with high grades of nickel, copper, cobalt and platinum group metals – predominantly palladium.

“We are keenly awaiting the report on the latest metallurgical test work, which we believe will further confirm the exceptional value of our mineralisation and its potential to be commercialised.
“We believe the discoveries to date may only be a fraction of the mineralisation in the high-grade mineral system at Mt Alexander.
“We will continue our systematic exploration in 2020 to test the potential for more deposits down-plunge of the shallow mineralisation and also along strike to the east and west.”
Latest test work focusing on gold and PGE recoveries
Preliminary metallurgical test work completed in October 2016 confirmed that the mineralisation tested was amenable to flotation processes with separate nickel and copper concentrates produced.
The new test work will aim to repeat these excellent results as well as to maximise the recovery of gold and platinum group elements (PGEs).
