MORE HIGH-GRADE NICKEL-COPPER SULPHIDE TARGETS AT MT ALEXANDER

Soil survey at the Fish Hook Prospect identifies a nickel soil anomaly with a strike of 700m:

• 1,260 soil samples from Fish Hook return assays that include anomalous values indicative of ultramafic rocks below surface

• Most highly anomalous assays connect in a linear trend consistent with the interpreted eastern extension of the mineralised Cathedrals ultramafic

• Surface moving loop electromagnetic (MLEM) survey to be completed at Fish Hook ahead of maiden drill programme

Extensive geophysical surveys being launched across the Cathedrals Belt to identify further

nickel-copper sulphide targets:

• MLEM survey to be completed at the Bullets, West End and Fish Hook Prospects

• High temperature SQUID sensor being used in the MLEM survey to minimise potential interference by conductive cover and to optimise depth of penetration

• Inaugural seismic survey planned for the Cathedrals Belt to investigate the structures associated with the mafic-ultramafic intrusives that host nickel-copper sulphides

Drilling of EM conductors continues:

• MAD172 underway to test the first of seven electromagnetic (EM) conductors identified so far by the downhole EM (DHEM) surveys in the recently completed deep stratigraphic holes along the Cathedrals Belt

• The target EM plate is modelled with conductivity of 25,000 Siemens and at a depth of 260m downhole – the deepest conductor drilled to date at the Cathedrals Belt

Growth-focused Western Australian nickel company St George Mining Limited (ASX: SGQ ) (“ St George ” or “ the Company ”) is pleased to announce that ongoing exploration programmes have generated additional strong targets for the discovery of more nickel-copper sulphides at the Mt Alexander Project, located in the north-eastern Goldfields.

Laboratory assays have been received for the comprehensive soil survey completed at the Fish Hook Prospect. The ground at Fish Hook is covered by up to 10m of aeolian sands with no outcrop of ultramafic rocks that would otherwise be used to target initial exploration for nickel-copper sulphide mineralisation.

The soil survey has identified a large geochemical anomaly, coincident in nickel, copper and chromium, that forms in an east-west trend and is consistent with the interpreted surface position of the southern ultramafic unit at Fish Hook.

Importantly, this unit is interpreted to be located along the eastern extension of the mineralised trend that hosts the currently known nickel-copper sulphide deposits of the Cathedrals Belt.

The nickel anomaly is also coincident with linear magnetic features observed in the magnetic surveys for the Fish Hook area and which are interpreted to represent ultramafic stratigraphy.

A MLEM survey will now be completed over the prospective areas of the Fish Hook Prospect to search for any conductors that may represent nickel-copper sulphides.

This survey will also be completed at a number of other unexplored or underexplored areas of the Cathedrals Belt, where there is potential for new EM targets to be identified.

Optimised MLEM Survey:

The new MLEM survey being deployed at the Cathedrals Belt will use a high temperature SQUID (superconducting quantum interference device) sensor that operates to minimise noise levels from conductive cover. This facilitates the collection of higher resolution EM data and deeper penetration of EM signals.

The survey will also utilise both traditional and Slingram configurations – the latter uses a sensor inside and outside of the survey loop, which further minimises any interference from conductive cover.

Figure 1 shows the areas to be covered by the new MLEM survey. These will include:

• West End Prospect: The western extension of the Cathedrals Belt remains largely unexplored, partially because of cover, including the area where the Cathedrals Belt intersects the Ida Fault. SAM (Sub Audio Magnetic) data has mapped a continuation of the structures that host the mineralised ultramafic at Investigators for more than 2km into the West End Prospect.

The new MLEM survey wiill assist to identify any conductive targets associated with these structures.

• Fish Hook Prospect: The recent soil geochemical survey at the Fish Hook Prospect (see below for further details) identified an anomalous trend along the horizon that is known to be prospective for nickel-copper sulphide mineralisation elsewhere in the Cathedrals Belt.

Given most of the Fish Hook area has a thin veneer of conductive cover, Slingram MLEM will now be used to more effectively screen the prospective horizon between the Fish Hook and the Bullets areas.

• Bullets Prospect: One drill hole completed at Bullets intersected the mafic-ultramafic intrusion that is known to host high-grade mineralisation in other parts of the Belt.

The MLEM survey will assist in the search of potential mineralisation associated with this intrusive unit, and will focus on the area to the north of previous drilling.

• Stricklands Prospect: A small MLEM survey will be completed on the western extension of the Stricklands Prospect to follow up recent drilling success along the mineralised horizon and to assist with further drill planning in that area.

Fish Hook Prospect – Soil Surveys Confirm Ultramafic Trend:

The Fish Hook Prospect covers an interpreted eastern extension of the east-west oriented Cathedrals Belt located within Exploration Licence 29/954 (100% owned by St George).

A trial soil survey was completed at Fish Hook earlier this year and returned highly anomalous geochemical values for nickel, copper and chromium – indicative of an ultramafic with nickel-copper sulphides.

Significantly, the soil assay was coincident with a linear magnetic feature which has been confirmed by drilling in other parts of the Cathedrals Belt as representing highly mineralised ultramafics.

A comprehensive soil survey was subsequently completed across the 8km east-west strike of the Fish Hook Prospect, with a total of 1,260 samples collected on 200m spaced lines with 20m sample spacing. Due to challenging cover conditions, approximately 30% of the survey is considered to be effective.

Within that area of effectiveness, the laboratory assays for the soil survey have identified a large nickel anomaly over an east-west trend of more than 700m. Figure 2 highlights the location of the nickel anomaly.

Importantly, the very high nickel-copper soil anomaly identified by the trial soil survey (assay MAS00340) lies within this broader nickel anomaly.

The large nickel anomaly and surrounding areas are considered prospective for nickel-copper sulphide mineralisation and will now be screened by a MLEM survey to identify drill targets.

For further details on Fish Hook, see our ASX Release dated 11 July 2019 ‘Further Priority Nickel-Copper Sulphide Targets’.

Seismic Survey:

As part of the escalation of geophysical surveys across the Cathedrals Belt, the first-ever seismic survey at the Belt is being designed.

Deeper drilling completed in the current programme has confirmed significant down-plunge extensions of the mineralised ultramafic.

Mineralisation remains open at depth in the north-west down-dip direction of the mineralised ultramafic, supporting the potential for ongoing exploration to establish further significant continuity of the nickelcopper sulphides.

The purpose of the seismic survey will be to map the structures through which the mafic-ultramafic intrusions hosting nickel-copper sulphides have passed upwards from the Earth’s mantle, and to detect any significant mineralisation accumulated at depth within these structures.

Further details of the seismic survey will be announced once the planning of the survey is complete.

John Prineas, St George Mining’s Executive Chairman, said:

“Our systematic exploration programmes continue to successfully scope out the scale of the large mineral system at the Cathedrals Belt.

“The soil survey results at Fish Hook are very encouraging because they have identified a new anomalous trend 5km east of the known nickel-copper mineralisation at the Cathedrals Belt. This is an area that we believe is prospective for a greenfields discovery.

“We are also pleased to be rolling out a new moving loop EM survey at Fish Hook and other unexplored areas of the Cathedrals Belt where there is strong potential to generate more EM targets for drill testing.

“The seismic survey is another exciting initiative with the potential to deliver an exploration breakthrough that could assist us to better understand the controls and distribution of the high-grade mineralisation along the Belt.”

DRILL PROGRAMME CONTINUES

Table 1 contains details of the completed holes for the current drill programme at Mt Alexander.

Diamond drilling is continuing with MAD172 currently in progress at Investigators. The hole is targeting an EM plate modelled with conductivity of 25,000 Seimens and predicted to be intersected at 260m downhole.

MAD169, MAD170 and MAD171 have been completed since our last exploration update on 29 October 2019. All three holes were deep stratigraphic holes at the Investigators Prospect.

MAD169:

MAD169 was completed to a downhole depth of 300m and intersected an ultramafic unit between 219.5m to 223m downhole with weakly disseminated sulphides and rare blebby sulphides (1-5% sulphides) comprising pentlandite (pn), chalcopyrite (cp) and pyrrhotite (po).

MAD170:

MAD170 was completed to a downhole depth of 351m and intersected a very thick mafic-ultramafic unit between 225.8m to 279.65m downhole. No significant suphides were observed.

The results of MAD169 and MAD170 are interpreted to be significant as they have intersected the down-dip extension of the intrusive mafic-ultramafic that hosts high-grade mineralisation at Investigators.

MAD171:

MAD171 was completed to a downhole depth of 250m and intersected mostly granite with no sulphides observed.

A DHEM survey will be completed in all three holes to search for further mineralisation around the holes.

Based on the intersection angle of the drilling with the modelled ultramafic unit, downhole widths are interpreted to be close to true widths.

Nickel and copper values shown above for recently completed drill holes are based on portable XRF analysis. They are preliminary in nature and a conclusive determination of the nickel, copper, cobalt and PGE values of the sulphide mineralisation will be confirmed when laboratory assays are available.

Average XRF readings in the massive sulphide interval are based on at least four readings per metre (unless otherwise stated) and are not length and density weighted.

Metal content for intervals of disseminated sulphides are not accurately determined by portable XRF analysis and estimates for this style of mineralisation are based on geological logging.
