Growth focused Western Australian nickel company St George Mining Limited (ASX: SGQ) has provided an update on the drilling and resource development programs in progress at its flagship high-grade nickel-copper sulphide Mt Alexander project, located in the northeastern Goldfields of WA.
Resource development milestones achieved at the shallow, high-grade nickel-copper sulphide deposit at the Stricklands Prospect:
Reverse circulation (RC) drill-out has finished with 4,077m of RC drilling completed.
Metallurgical and geotechnical diamond core drilling at Stricklands has finished with 661.6m of PQ diamond drilling completed.
Core samples are being sent to Canada for detailed metallurgical testwork.
Diamond drilling of new conductive targets at the Investigators Prospect is underway:
Drilling of the first deep hole – MAD180 – to test the large conductive target at Investigators identified by the magnetotelluric (MT) and audio-magnetotelluric (AMT) surveys has commenced.
MAD180 is planned to be drilled to a downhole depth of 800m.
Second diamond rig is scheduled to arrive at site on or about 14 July 2020, with both diamond rigs to operate 24/7.
Resource development at Stricklands reaches key milestones: The resource drill-out of the shallow, high-grade nickel-copper sulphide deposit at Stricklands has concluded with 52 drill holes completed for 4,077m of RC drilling.
Drill holes were completed on close-spacing of between 10m to 20m. Samples from the drilling have been dispatched for laboratory assaying in Perth.
The shallow Stricklands mineralisation has been defined over an area that is approximately 450m long, 50m wide and 80m deep.
Entech, the external geological consultancy engaged by St George to issue a JORC-compliant resource estimate for Stricklands, will receive all drill hole data and assay data as soon as available.
The resource estimate, once issued, will be used in the scoping study for a potential mining operation at Mt Alexander including the design of alternative open-pit shells for mining.
John Prineas, St George Mining’s Executive Chairman, said:
“We are very pleased to have completed the resource drill-out at Stricklands as well as the metallurgical holes required for resource development work.
“These are important milestones for the scoping study into a potential starter mine at Mt Alexander.
“The thick intercepts of nickel-copper sulphides in the latest met holes are a reminder of the excellent mineralisation that we have at Stricklands.
“Drilling of the deep MT conductive targets has now commenced with drill hole MAD180 targeting the compelling new conductive feature at Investigators.
“A second diamond rig is scheduled to arrive at site shortly which will accelerate testing of these new and exciting deep conductive targets.“
