Maiden RC Drilling At Carnac Prospect Intersects 85m Horizons
St George Mining Limited (ASX: SGQ) has identified new exploration potential with current drilling activities underway at its flagship high- grade Mt Alexander Project, located in the north-eastern Goldfields in Western Australia.
“Early results from the RC drilling at Mt Alexander are very promising with multiple prospects emerging that look highly prospective for more significant nickel discoveries,” John Prineas, St George Mining’s Executive Chairman, said.
“The geology encountered in the drilling at the Carnac and Jailbreak prospects fits the respective geological models that we are targeting in these areas.
“The thickness of the prospective units intersected at both Carnac and Jailbreak is very impressive and provide a significant search horizon for potential nickel sulphide mineralisation.
“We look forward to progressing our systematic exploration of these prospects which are located within our 100%-owned tenements at Mt Alexander.
“The multiple new exploration targets established across our project tenure – in addition to the high-grade discoveries already made at the Cathedrals Belt – support the potential for Mt Alexander to develop into a major nickel camp with multiple high-grade nickel-copper sulphide deposits.
“We will keenly await the data from the seismic survey at the Cathedrals Belt ahead of resuming our deep diamond drilling at Mt Alexander.
“The seismic survey will provide crucial information regarding the orientation and behaviour of the intrusive-host structure at depths of up to 1.5km, to give us more accurate modelling of current drill targets and provide further targets beyond the scope of current EM surveys.
“With diamond drilling at both Mt Alexander and our Paterson Project due to kick off again shortly, we expect a very busy and important period of newsflow at a time when the market is looking for exciting exploration news.”
Seven drill holes were completed at the newly identified Carnac Prospect – MARC139, MARC140, MARC141, MARC142, MARC143, MARC144 and MARC145. Carnac is located on E29/1041 (100% St George).
The drill holes were designed to test a linear magnetic trend that extends east-northeast across the Carnac Prospect for more than 8km.
Drilling has successfully confirmed the presence of mafic-ultramafic intrusive- style rocks that have the same geochemical signature as the rocks seen at the east-northeast trending Cathedrals Belt, giving support for the potential of Carnac to also host high-grade nickel-copper sulphides similar to those on the Cathedrals Belt.
The soil survey at Carnac which returned anomalous values for nickel, copper and chromium was only partly completed prior to this RC drilling. The encouraging results from the drilling warrant a broadening of the soil survey over the remainder of the trend towards the east.
Follow-up activity will be planned once the results of the current drilling and soil survey are reviewed.
CATHEDRALS PROSPECT – INFILL DRILLING
RC drilling has now commenced at the Cathedrals Prospect where high-grade nickel-copper sulphides have been discovered from 30m below surface with two distinct deposits recognised.
Drilling will focus on the upper deposit, situated largely between 30m to 80m below surface and hosted within the intrusive Cathedrals mafic-ultramafic.
Initially, 25 drill holes will be completed with an average depth of 80m to test the potential extension of known mineralisation into areas where there has been no drilling.
Additional infill drilling will be designed once results from the initial holes are reviewed.
SEISMIC SURVEY HAS COMMENCED
The first ever seismic survey at the Cathedrals Belt is underway. The survey will comprise up to 20km of five 2D seismic lines that are oriented north-south across the Cathedrals Belt at the West End and Investigators Prospects.
The seismic survey is expected to map the intrusive-host structure up to 1.5km below surface. A number of EM conductors have been identified in this area by recent DHEM surveys.
Based on drilling to date, the intrusive-host structure is interpreted to dip to the north-northwest at 40 degrees. The seismic survey will confirm if the structure continues at depth with this orientation or takes a different direction.
Any major change in trajectory would provide a potential trap site for sulphide accumulations and thus a high priority drill target.
Surface EM surveys have limited depth penetration, with the latest DHEM conductors identified well below the reliable detection range.
The seismic data will assist in better targeting these EM conductors as well as other areas at depth with potential for hosting accumulations of massive sulphides. For further details of the EM conductors in this area,
