St George Mining Limited (ASX: SGQ) has commenced a substantial diamond core drill programme at its 100% owned Paterson Project located in the East Pilbara region of Western Australia.
“We are delighted to commence diamond drilling at the Paterson Project where our 2021 air-core reconnaissance drilling identified elevated levels of pathfinder elements for base metal and gold deposits,” Executive Chairman, John Prineas, said.
“The targets being tested are high-priority areas coincident with favourable structural features seen in the data from gravity and airborne magnetic surveys completed by St George.
“While this exciting drill programme is underway at the Paterson, we will complete further geophysical surveys at our Mt Alexander Project. These new seismic and EM surveys will assist in fine-tuning nickel-copper sulphide targets for the next drill programme at Mt Alexander.
“We look forward to reporting further on these important field programmes as results are received.”
Diamond Drilling to Follow-Up Maiden 2021 AC Programme
Several of the shallow air-core holes drilled in 2021 at the Paterson Project intersected visible chalcopyrite and locally intense alteration that was confirmed with petrology.
Highly Successful Drilling at Paterson Project
Drill holes in the 2021 air-core programme also intersected metasediments interpreted to belong to the prospective lower Yeneena Basin which hosts substantial copper and gold discoveries in the northern Paterson Province.
Significantly, this is same stratigraphic package that hosts Rio Tinto’s major copper-gold Winu discovery located 50km south-west of St George’s project area.
High-resolution gravity and airborne magnetic surveys completed by St George at its 100%-owned E45/5226 also identified prominent geophysical and structural features that are interpreted to be similar to those known to be associated with major precious and base metals discoveries in the region.
These results strongly support the potential for copper and gold mineralisation across the 35km prospective stratigraphy hosted in E45/5226.
Two target areas have been prioritised for testing in the current diamond drill programme.
• Target Area 1: Two large structurally complex anticlinal folds with interpreted intrusive granite cores and bounded by regional scale faults. Visible copper was observed in air-core chips from the 2021 drilling on the west limb of the anticline.
• Target Area 2: Large, interpreted domal anticline structure bounded by regional scale faults. In particular, the regional anticlines interpreted from airborne magnetic data in the project area may represent similar geological settings to Rio Tinto’s Winu deposit.
Both target areas are considered prospective for vein hosted base metal and gold mineralisation.
