St George Mining Ltd (ASX:SGQ) has intersected massive nickel-copper sulphides in the first ever drilling at the Stricklands Prospect, which is located within the Mt Alexander Project in Western Australia.
Drill holes MAD20, MAD22 and MAD23 targeted separate modelled EM conductors at the Stricklands Prospect, and all three have intersected nickel-copper sulphide mineralisation at shallow depths.
John Prineas, executive chairman, commented:
“The discovery of massive nickel-copper sulphides in the first ever drill program at Stricklands illustrates the strong potential that exists for additional new discoveries at Mt Alexander.
“The effectiveness of EM techniques and our rapidly increasing knowledge of the geology of the region are substantially enhancing the prospectivity of the project.
“With more EM targets being defined and drilling ongoing, we are in an excellent position to deliver further exploration success.”
Stricklands is located within the Cathedrals shear zone, 1 kilometre west-southwest of the Cathedrals Prospect where the initial discovery of nickel-copper sulphides was made by BHP Billiton in 2008.
