PORTFOLIO OF GOLD TARGETS AT EAST LAVERTON
St George Mining Limited (ASX: SGQ ) (‘St George Mining’ or ‘the Company’) is pleased to provide an update on the major drill programme to test gold targets at its 100% owned East Laverton Project in Western Australia.
This drill programme is testing a portfolio of gold targets located on the greenstone belts within the 2,000 sq km East Laverton Project. A total of 100 RC drill holes have been completed to date for 7,304m drilled.
The reconnaissance drilling is designed to advance areas of gold anomalism to better assess if they may be associated with primary gold mineralisation and require further drilling. The current programme is also drilling several deeper targets where shallow gold mineralisation has been identified indicating prospectivity for bedrock gold mineralisation.
Early drill results are encouraging with multiple drill holes logged as intersecting mafic rocks, including dolerite, with intervals of prominent hydrothermal alteration containing sulphide mineralisation and quartz veining.
Assays received to date indicate significant gold anomalism and prospectivity at the Cambridge and Cambridge North targets that warrants follow-up exploration. Assays for drilling at the other targets are pending.
St George Mining Executive Chairman, John Prineas said:
“The 2017 drill programme is testing a range of gold targets at the East Laverton Project, with most areas drilled for the very first time.
“Already we are seeing encouraging results with potential for significant gold mineralisation at some of the targets, and we are keenly awaiting the remaining assay results.”

Desert Dragon:
The Desert Dragon gold prospect is located along the Stella Range belt, and encompasses an area where the belt undergoes significant folding and structural deformation. Two tight folds in the belt have been identified as target areas for potential gold mineralisation.
Numerous drill holes at Desert Dragon have intersected gold anomalism. These include DDD010, drilled by St George in 2014, which intersected 6m @ 0.70g/t Au including 2m @ 1.42g/t Au from 149m. The gold mineralisation is associated with a strongly sulphidic metasedimentary unit (26% sulphur). The mineralised horizon is also intersected 100m to the east and up-dip in DDRC049 (4m @ 0.3 g/t Au).
Dr Walter Witt, in his review earlier this year of the gold targets at the East Laverton Project, completed a detailed analysis of all historical exploration data, including drill hole data, soil surveys, geological mapping and geophysical surveys. Figure 2 illustrates the detailed targeting analysis by Dr Witt at Desert Dragon, and highlights two of the priority targets recommended for test drilling at this prospect.
Dr Witt noted the presence of the following features favourable for gold prospectivity:
-
Widespread multi-element (Au, Cu and Mo) soil anomalies
-
Folds in the belt with reactive Fe-rich unit
-
Widespread geochemical indicators of potassic (Rb/K2O) and carbonate (Sr/CaO) alteration in holes drilled into reactive Fe-rich units
-
Anomalous (W+Mo+Bi) geochemistry that suggests the presence of oxidised magmatichydrothermal fluids
-
Anomalous (As+Sb) geochemistry that suggests S-rich sediments and not reduced hydrothermal fluids

The coincidence at Desert Dragon of pathfinder elements and structural architecture that are typically associated with gold systems make this prospect a high priority area for further gold exploration.
Eight drill holes are planned for Desert Dragon in the current drill programme, four holes in each of the target areas shown in Figure 2. Drilling at Desert Dragon is scheduled for next week.

Bristol:
The Bristol gold prospect is located along a greenstone belt in the central area of the East Laverton Project, and is associated with a large magnetic and gravity body.
Historical gold drilling has been completed mostly on the western side of the Bristol magnetic body within a complex and sheared contact between a late alkaline granite intrusive centre to the west and the greenstone to the east.
Both historical drilling and drilling completed by St George in 2016 over this area has intersected anomalous regolith gold over a strike of 1,500m. This substantial supergene gold at Bristol is consistent with a proximal and more significant primary gold-bearing source.
Like most gold deposits, a concentration of primary gold mineralisation is likely to be associated with a significant structural intersection of reactivated fundamental north-west trending and east-west transform faults.

Such an area is located to the north of the regolith gold anomaly, where three main structures intersect. These are the north-trending greenstone belt, a major NW trending fold axes and a NE-SE trending fundamental transform fault that forms part of the Churchill Lineament.
Dr Witt, in his review of the Bristol prospect, identified this area as a priority target in recognition of the highstrain rheological (ultramafic-granite) contact, including fault bends and intersections along strike. The high strain zone is outlined in red, in Figure 3, and there is no effective drilling in this area.
Three drill holes were completed at Bristol and assays are pending.

Windsor:
The Windsor prospect is located at the southern section of the Stella Range belt. The gold target at Windsor is associated with prominent magnetic anomalies in the eastern part of the Windsor prospect area, where drilling has been very limited.
Sixteen (16) drill holes have been completed to test two prominent magnetic anomalies; see Figure 4. Drilling intersected strong hydrothermal alteration and sulphide mineralisation within a mafic/dolerite host, with assays pending. Figure 5 contains an example of drill chips from WINRC032.

Cambridge North:
A 3.6km long north-south mineralised structure at Cambridge North has been confirmed by the recent drilling as a priority target for follow-up exploration. The Cambridge North target is located on the northern extension of the Stella Range greenstone belt.
-
The mineralised structure was first identified by historical drilling that included the following intersections: • 3m @ 0.97g/t Au from 27m within a larger gold halo of 10m @ 0.37g/t Au in SRAB081
-
3m @ 0.51g/t Au from 36m in SRAB083.
Previous reconnaissance drilling by St George also identified gold anomalism with the following intersections:
-
14m @ 0.237g/t Au from 32m and 3m @ 0.17g/t Au from 136m in CNR002
-
7m @ 0.54g/t Au from 35m including 1m @ 1.73g/t from 39m and 4m @ 0.24g/t Au from 84m in CNRC003
The latest drilling by St George has identified further gold anomalism with intersections of:
-
4m @ 0.07g/t Au from 52m within a larger gold halo of 24m @ 0.03g/t Au in CNRC011
-
4m @ 0.11g/t Au from 32m within a larger gold halo of 20m @ 0.06g/t Au in CNRC025

CNRC011 and CNRC025 are spaced 2km apart. Importantly, they are along the same trend and in a consistent stratigraphic position. The drill holes intersected dolerite with quartz veining, which is indicative of alteration that may be associated with gold mineralisation. There is no effective drilling between these two intersections or to their west, indicating significant exploration upside along this underexplored mineralised structure.
Cambridge:
The Cambridge gold prospect is associated with a large dunite body situated to the immediate east of the Stella Range Belt. Figure 7 illustrates the four target areas at Cambridge that were tested in the current drill programme.
Two targets, Targets C and D, intersected gold anomalism – as indicated in Figure 8 - that warrants follow-up exploration.

Figure 8 – gold anomalism at Targets C and D at Cambridge (plan view map against RTP magnetics)
Target C encompasses the intersection of a fold axis and a reactive Fe-rich unit, and drilling has confirmed the presence of supergene gold in dolerite mafic rocks.
Target D is a bulls-eye magnetic anomaly with drilling also confirming the presence of supergene gold in a BIF unit. Strong hydrothermal alteration and quartz veining were noted in the drill chips for the completed drill holes at these targets.
A follow-up drill programme is being designed for these targets to test for primary gold mineralisation in the bedrock.

| marked up at 1m intervals against the drillers blocks, which are | ||

| The visible structural features on the core are measured against the | ||
| core‐orientation lines. | ||
| RC Sampling: All samples from the RC drilling are taken as 1m | ||
| samples. Samples are sent to Intertek Laboratories for assaying. | ||
| Appropriate QAQC samples (standards, blanks and duplicates) are | ||
| inserted into the sequences as per industry best practice. Samples are | ||
| collected using cone or riffle splitter. Geological logging of RC chips is | ||
| completed at site with representative chips being stored in drill chip | ||
| trays. | ||
| Onsite XRF analysis is conducted on the fines from RC chips using a | ||
| hand‐held Olympus Innov‐X Spectrum Analyser. These results are | ||
| only used for onsite interpretation and preliminary assessment | ||
| subject to final geochemical analysis by laboratory assays. | ||

| return for that metre. This results in a representative sample being | ||
| taken from drill return, for that metre of drilling. The remaining | ||
| majority of the sample return for that metre is collected and stored | ||
| in a green plastic bag marked with that specific metre interval. The | ||
| cyclone is blown through with compressed air after each plastic and | ||
| calico sample bag is removed. If wet sample or clays are encountered | ||
| then the cyclone is opened and cleaned manually and with the aid of | ||
| a compressed air gun. | ||
| A large auxiliary compressor (“air‐pack”) is mounted on a separate | ||
| truck and the airstream is connected to the rig. This provides an | ||
| addition to the compressed air supplied by the in‐built compressors | ||
| mounted on the drill rig itself. This auxiliary compressor maximises | ||
| the sample return through restricting air pressure loss, especially in | ||
| deeper holes. In addition, the high and consistent levels of air | ||
| pressure minimise the number of drill samples. | ||
| Geological logging of RC chips is completed at site with representative | ||
| chips being stored in drill chip trays. Downhole surveys of dip and | ||
| azimuth are conducted using a single shot camera every 30m to | ||
| detect deviations of the hole from the planned dip and azimuth. The | ||
| drill‐hole collar locations were recorded using a hand held GPS, which | ||
| has an accuracy of +/‐ 5m. At a later date the drill‐hole collar will be | ||
| surveyed to a greater degree of accuracy. | ||

Assays are undertaken at Intertek in Kalgoorlie and Perth. Samples are sent to Intertek where they are crushed to 6 mm and then pulverised to 75 microns. A 30 g charge of the sample is fire assayed for gold, platinum and palladium. The detection range for gold is 1 – 2000 ppbAu, and 0.5 – 2000 ppb for platinum and palladium. This is |
|
| believed to be an appropriate detection level for these elements | ||
| within this specific mineral environment. However, should Au, Pt or | ||
| Pd levels reported exceed these levels an additional assay method | ||
| will be used to re‐test samples. | ||
| All other metals will be analysed using an acid digest and an ICP finish. | ||
| The sample is digested with nitric, hydrochloric, hydrofluoric and | ||
| perchloric acids to effect as near to total solubility of the sample as | ||
| possible. The solution containing samples of interest, including those | ||
| that need further review, will then be presented to an ICP‐OES for the | ||
| further quantification of the selected elements. | ||
