Drilling Multiple, Deeper Nickel-Copper Sulphide Targets
St George Mining Limited (ASX: SGQ) has kicked off a diamond drilling programme to test deeper nickel-copper sulphide targets at its flagship high-grade Mt Alexander Project, located in the north-eastern Goldfields in Western Australia.
Executive Chairman, John Prineas, said the drill targets are at Investigators and West End and associated with a number of electromagnetic (EM) conductors/
“We are delighted to resume diamond drilling at Mt Alexander, particularly given the portfolio of exciting nickel-copper sulphide targets that we have identified and lined up for drilling,” Mr Prineas said.
“Our ongoing systematic exploration at the West End and Investigators Prospects has produced excellent results this year including a new, deeper discovery at MAD199 and a growing number of downhole EM conductors.
“These results all point to a very large and fertile mineral system at West End and Investigators that has the potential to host a significant volume of mineralisation.
“This area remains underexplored and only lightly drilled, providing an opportunity for further drilling to deliver exciting discoveries to expand the mineralised footprint that we have identified at Mt Alexander.
“We look forward to reporting results over the coming weeks.”
Targets
Diamond drilling has commenced at Mt Alexander on a double-shift basis to ensure drilling is carried out 24/7.
MAD203: The first hole to be drilled will target an area approximately 80m east of the MAD199 discovery. The hole is located halfway between MAD199 and MAD173, which also intersected massive nickel-copper sulphides on the basal contact and returned assays of 3.21m @ 1.35% Ni, 0.8% Cu and 998ppb PGEs from 271m. The intrusive-host structure is interpreted to continue from MAD173 westwards to MAD199. The new drill hole will test for continuity of mineralisation along this 180m strike between the two holes.
MAD204: The second hole will be a step-out from MAD202. The new drill hole will target the very strong 81,000 Siemens off-hole conductor identified from the DHEM survey in MAD202. The area is associated with a large gravity anomaly representing a body of dense rocks that is interpreted to be massive sulphide accumulations.
MAD205: The third hole will target a large 250m-strike off-hole conductor identified from the DHEM survey in MAD200 which intersected preserved disseminated nickel-copper sulphides on the basal contact. The hole is designed to test the Mt Alexander geological model using the DHEM conductor as a vector to potential further nickel-copper sulphide deposits down-dip and down-plunge from MAD200.
MAD206: The fourth drill hole will target the down-plunge continuity of the discovery in MAD199 towards the west. The hole is designed to test continuity of mineralisation beyond the scope of downhole or surface EM surveys.
Successful drilling would increase the mineralised envelope by approximately 100m west or down plunge. The first step-out hole for MAD199, MAD201, intersected massive nickel sulphides 125m down-dip of the MAD199 discovery.
The downhole EM survey in MAD201 identified three very strong off-hole EM conductors with modelled conductivity of 120,400 Siemens, 30,000 Siemens and 23,000 Siemens, respectively.
These conductors support the potential for significant mineralisation in the vicinity of MAD199 and MAD201.
