THE DRILL SERGEANT: St George Mining (ASX: SGQ) announced location of a new EM target for massive nickel-copper sulphides at the company’s Mt Alexander project, located in the north-eastern Goldfields.

St George Mining reported the EM conductor is modelled with conductivity of 81,000 Siemens, claiming it to be one of the highest of any conductor identified at Mt Alexander to date.

The conductor was observed in the mid to late time data of a recent DHEM survey and recorded a time constant of 100 milliseconds.

The company explained combination of conductivity and time decay of this kind are typical of massive sulphides.

The new EM conductor is coincident with a trend of prominent gravity highs that have been interpreted to represent dense rocks – further confirming the conductor as a compelling target for mineralisation.

Of note, the new conductor is close to several other EM conductors recently identified by the DHEM surveys at West End and Investigators – in drill holes MAD196, MAD199, MAD200 and MAD201.

This field of multiple conductors supports the potential of substantial sulphide mineralisation in this underexplored area of the Cathedrals Belt.

“Our systematic and concurrent use of drilling and downhole EM surveys has delivered another stand-out result with the identification of one of the most exciting EM conductors at Mt Alexander to date,” St George Mining executive chairman John Prineas said in the company’s ASX announcement.

“We have a 100 per cent success rate in confirming conductors of this kind as nickel-copper sulphides, so we are confident that drilling this target will deliver another discovery of high-grade mineralisation.

“The growing number of significant mineralised intercepts and downhole EM conductors at West End and Investigators demonstrates a very large and fertile mineral system and further supports the potential for a significant deposit in this area.”

THE DRILL SERGEANT: St George Mining (ASX: SGQ) has continued to produce promising exploration results at the company’s high-grade Mt Alexander project in the north-eastern Goldfields of Western Australia.

St George drilled hole MAD201 as a large step-out from the 10.96 metres of nickel-copper sulphides that had previously been encountered by discovery hole MAD199.

MAD201 was drilled to test for extension of mineralisation at depth and intersected a 16m thick intrusive unit from 421m downhole that included a 2.4m interval of nickel-copper sulphides from 434.6m downhole.

MAD201 is the first step-out hole from MAD199 with mineralisation open in all directions.

“The mineralised intersection in MAD201 is an excellent result for the large step-out from the MAD199 discovery as it has identified a potential 125 metres down-plunge extent of mineralisation,” St George Mining executive chairman John Prineas said in the company’s ASX announcement.

“The strong EM conductors identified from the downhole EM survey in MAD201 further support the likelihood of additional mineralisation being present in this area.

“Our systematic exploration approach of the large intrusive mineral system at the Cathedrals Belt is now delivering tangible breakthrough results.

“We are confident that further drilling will continue to grow the footprint of high-grade mineralisation at the Cathedrals Belt coinciding with strong capital markets focus on identifying the next generation of nickel sulphides supplies.”

THE DRILL SERGEANT: St George Mining (ASX: SGQ) has commenced a multi-rig drill program at the company’s Mt Alexander project, located in the north-eastern Goldfields of Western Australia.

This program is to include reverse circulation (RC) drilling across a range of nickel-copper sulphide targets and diamond drilling testing new conductive features identified by magnetotelluric (MT) and audio-magnetotelluric (AMT) surveys completed earlier this year.

St George explained the new conductive targets are located deeper than the current extent of drilling and believes they have potential to deliver new nickel-copper sulphide discoveries.

RC drilling has already started and will focus on testing shallow targets at the Fish Hook and West End Prospects, as well as completing the resource definition drilling at the high-grade Stricklands deposit.

“We are excited to be commencing this highly anticipated drill program at Mt Alexander,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.

“The shallow deposits discovered to date confirm that the mineral system at the Cathedrals Belt hosts outstanding mineralisation with high grades of nickel, copper, cobalt and platinum group metals.

“The MT survey completed this year has confirmed the presence of conductive features beyond the current extent of drilling.

“This new data is a significant breakthrough in exploration at Mt Alexander.

“It has provided a blueprint to the structural framework of the mineral system that will guide our drilling of the deeper targets.

“In addition to drilling these deep conductive targets, we are excited to begin the first ever drilling at the Fish Hook prospect.

“With a high-order soil anomaly coupled with EM anomalism and interpreted ultramafic intrusives, this drilling has the potential to deliver another greenfields nickel sulphide discovery.

“We are also pleased that this drill campaign will include the resource definition at the shallow Stricklands deposit.

“With high-grade mineralisation starting 30 metres from surface, we believe Stricklands can support a low capital cost, high-margin mining operation that we can fast-rack to development.”

THE DRILL SERGEANT: St George Mining (ASX: SGQ) has identified a raft of new exploration targets at the company’s Mt Alexander nickel-copper sulphide project in the north-eastern Goldfields of Western Australia.

St George Mining completed an MT/AMT survey at Mt Alexander that was designed to map structures and conductive rock types (including mafic/ultramafic intrusives) along two key sections of the Cathedrals Belt that are known to host nickel-copper sulphide mineralisation.

The survey was also designed to identify repetitions of similar structures and stratigraphy in the underexplored tenements adjacent to the Cathedrals Belt.

The company reported that the interim results from the MT survey have indicated the presence and orientation of the prospective structures and potential mafic/ultramafic stratigraphy, opening up a new range of priority targets for nickel-copper sulphides.

At the Investigators prospect, data from the MT survey has clearly shown a conductive response that is coincident with the Investigators ultramafic where extensive high-grade mineralisation has already been discovered from near surface to more than 250 metres below surface.

The MT survey data also demonstrated conductive responses to be present at depth at the Fairbridge prospect, the West End prospect and to the north of Investigators on tenement E39/548 (owned 100% by St George).

These areas have also never been drilled.

“The results from the MT survey are a game-changer for exploration at the Mt Alexander project,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.

“We have already discovered high-grade nickel-copper sulphides at shallow depths across more than 5.5 kilometres of the Cathedrals Belt.

“However, intrusive mineral systems like we have at the Cathedrals Belt will typically have significant mineralisation at depth.

“These potential larger deposits are likely to be at deeper levels than explored to date at the Cathedrals Belt and our challenge has been how to best target drilling to discover these deeper, undercover deposits.

“The MT survey has gone a long way towards unlocking the geological model at the Cathedrals Belt by providing new and breakthrough insights into the stratigraphy and structural framework at depth.

“We now have a guide to where the granites have disrupted the ultramafics, how the ultramafics have been folded and – most importantly – where the deeper deposits may be located.

“We will revise the drill programme for Mt Alexander in light of this data and are very excited at the opportunity to test drill these new targets.

“The COVID-19 pandemic has created many challenges for our community and for our industry.

“We will carefully navigate this evolving period of uncertainty to protect the health and safety of our team and service providers, and to keep St George strong.

“We are undeterred in our commitment to deliver further exploration success at our projects and will be announcing more significant exploration initiatives over the coming weeks, including a revised drill program for Mt Alexander and our first exploration results at the new Paterson project where an airborne magnetic survey was completed this month.”

St George also announced the appointment of Entech as its external geological consultant to estimate a maiden JORC-compliant mineral resource at the Mt Alexander project.

A scoping study is scheduled that will focus on assessing a potential mining operation that can be developed with very low capital costs and a simple open-pit mining operation.

The resource estimate will initially focus on the Stricklands deposit – where thick massive nickel-copper sulphide mineralisation starts at 30m below surface.

St George considers Strickland to have the simplest potential mining operation among the four shallow deposits discovered so far across the Cathedrals Belt.

“The appointment of external geological consultants for a maiden resource estimate is another major step in the scoping study for the potential mining of the shallow deposits at the Cathedrals Belt,” Prineas continued.

“We are aiming to deliver an economically robust start-up mine with very low up-front capital costs and a high-value product with exceptional payabilities for nickel, copper, cobalt and platinum group metals that include palladium, platinum and rhodium.”

From the drill bit, St George received assays for drill hole MAD177, which it declared to have confirmed high-grade nickel-copper-cobalt-PGE sulphide mineralisation, including:

MAD177
10.5 metres at 4.82 per cent nickel, 1.67 per cent copper, 0.15 per cent cobalt and 2.87 total grasm per tonne PGEs from 182.5m, including 4m at 7.53 per cent, 2.47 per cent copper, 0.23 per cent cobalt and 3.92 total g/t PGEs from 186m.

Platinum group metals include high levels of Palladium and Rhodium – 10.5m at 2.33g/t Pd and 0.08g/t Rh, including 4m at 3.23g/t Pd and 0.1g/t Rh.

“The assays for MAD177 have again reminded us of the high quality of our mineralisation,” Prineas said.

“Long-term market demand for new high-grade nickel sulphide discoveries like Mt Alexander remains very strong and St George is exceptionally well positioned to take advantage of the economic bounce-back when the pandemic subsides.”
