DRILLING UPDATE – INTERIM RESULTS AT DRAGON 9
St George Mining Ltd ("St George" or "the Company") is is pleased to announce the latest update on its high impact drilling campaign at its 100% owned East Laverton Property in Western Australia.
Drill hole DDRDD0001 was designed to test the strong EM conductor at Dragon 9 and has been completed with an end of hole depth of 436m. Mafic, ultramafic and sulphidic sedimentary rock sequences were identified by visual logging of the drill core and this assessment is supported by the XRF analysis.
The Dragon 9 EM conductor was modelled by Newexco at a depth of 235m down hole, with a high conductance (4900 Siemens) and a very long time decay (443ms).
The hole intersected alternating sequences of mafic rocks and sulphide‐rich sediments between 219m and 255m with thin intervals of pyrrhotite, magnetite and some shales. There were no expected massive sulphide occurrences observed within this interval, where the conductor was modelled to be present.
A DHEM survey will be carried out at DDRDD0001 to test for the presence of any conductive material located near to the hole and to refine the modelling of the Dragon 9 EM conductor. The rocks encountered in DDRDD0001 are likely to be part of the target EM plate, although the relatively minor conductivity of the material intersected is not entirely consistent with the very powerful EM response of Dragon 9.
A review of all data will be completed in conjunction with Newexco to determine if any further testing of Dragon 9 is warranted. Any further drilling will be scheduled as part of the reverse circulation (RC) drilling programme that is planned to commence in September 2015.
Mr John Prineas, Executive Chairman of St George Mining said:
"We will review the geophysical aspects of Dragon 9 once the data from the downhole EM survey is received and complete follow‐up drilling if recommended. The area is very prospective and we have additional untested EM conductors there that we are continuing to evaluate.
"The drill rig is now at Dragon 5 where we have another opportunity to test a highly quality target for massive nickel sulphides.

"We have a tremendous pipeline of high quality prospects. There is over 40km of strike of prospective greenstone just in the Stella Range Belt and the targets we have drilled represent only a small footprint.
"We are confident that persistence, together with good technical and systematic exploration, will deliver a significant discovery."
A strongly anomalous base metal zone was identified in DDRDD00001 between two ultramafic units from 269m to 282m, with peak spot XRF values of 0.25% Cu and 0.77% Zn. Chalcopyrite was also identified further down the hole with a metre wide quartz vein at 406m downhole returning a spot XRF value of 4.2% Cu and 0.13% Zn (see Figure 1).
The rocks tested by this hole appear to have been strongly hydrothermally altered (chlorite + carbonate), consistent with the geochemically anomalous bismuth and molybdenum values present in intervals of elevated Cu and Zn. There is geochemically elevated copper (+100 ppmCu) throughout this hole.
A significant increase in sulphur was noted for the last 40m of the hole, which is comprised of mafic rocks that are chlorite‐carbonate altered, and has elevated copper values. It is the most consistent and highest sulphide intersection in DDRDD0001 noted from initial analysis. There appears to be a substantial introduction of hydrothermal pyrite at the base of the hole.
The geological logging and XRF analysis of the drill core from DDRDD0001 is ongoing, and the results described here are provisional in nature only. A conclusive determination of the metal contents, rock types and the stratigraphic and structural correlations will be confirmed once laboratory assays are available.

Figure 1 – Blebs of Chalcopyrite (copper sulphides) present within quartz vein sulphides at 406m in DDRDD0001. Spot XRF value of copper for this interval was 4.2% Cu.

NEW AND COMPELLING TARGET ‐ DHEM CONDUCTOR AT DESERT DRAGON NORTH
Hole DDNDD0001 was drilled to test the ultramafic rocks underlying the massive nickel sulphide stringers (2m @ 1.08% Ni from 55m) intersected in hole DDNRC002.
The recent DHEM survey for DDNDD0001 identified a strong off‐hole EM conductor situated 100m below and 50m north of DDNDD0001. Initial details of this EM conductor, named 'North Dragon 1', were provided in our ASX Release dated 29 July 2015 'Strong DHEM Conductor at Desert Dragon North''.
Newexco, our geophysical advisers, have completed further modelling of the DHEM survey data and have advised that "the off‐hole late time anomaly and resulting model create a compelling target for further exploration and drill testing is recommended."
John Prineas commented further on this new, high priority target:
"The exploration potential at Desert Dragon North is unfolding nicely with the new conductor being an excellent fit to our exploration model for this prospect.
"The massive nickel sulphide stringers discovered in hole DDNRC002 are interpreted to be part of a locally situated and larger accumulation of massive sulphides. The new EM target is a great illustration of the success that comes with patience, persistence and systematic exploration.
"We will complete geological modelling of the conductor once assays for DDNDD0001 are reviewed, and then schedule this exciting target for test drilling."
DDRDD0002 AT DRAGON 13
The XRF analysis of the drill core from hole DDRDD0002 has been completed with no significant mineralisation identified. The geological logging and interpretation of the drill core is continuing.
The hole was drilled to a depth of 550m and was predicted to intersect the Dragon 13 EM conductor, which is modelled as EM plate DD‐DDN‐03, at a depth of 500m.
A gyroscopic survey and DHEM survey will be completed at the hole later this week. Data from these surveys will allow for a better assessment of the final drill hole location in relation to the EM target.
If required, further drilling at Dragon 13 will be scheduled during the RC drilling programme that is planned to commence in September 2015.
LABORATORY ASSAYS
Samples of drill core from the completed holes have been progressively delivered to Intertek Genalysis throughout the drilling campaign for completion of laboratory assays. All samples are being assayed for a comprehensive suite of elements.
We anticipate an announcement regarding assay results for some of the initial drill holes later this week.
DRILLING UNDERWAY AT DRAGON 5
Drill hole DDRDD0008 has commenced at Dragon 5, which features a strong EM conductor that is co‐ incident with a large positive gravity feature (see Figure 2).
The conductor has been modelled by Newexco as EM plate DDS_03 with a short strike length of 250m and a modelled depth extent of 350m. The conductance is 3,500 Siemens with a time constant of 250ms, calculated over a number of late‐time channels. The EM signature of this conductor is consistent with that of a discrete massive sulphide body.

The geological context of the EM conductor is also favourable for the potential of massive nickel sulphides. The EM conductor is situated on the inferred lower contact of the ultramafic sequence and within a tight fold of the ultramafic belt, which is potentially a favourable structural position for the concentration of massive nickel sulphide.
Dragon 5 is located within a low magnetic domain (see Figure 2) which suggests a decreased likelihood for magnetic minerals, such as magnetite and pyrrhotite, to be the source of this EM conductor. This implies an increased prospectivity for this target, as the gravity and EM responses have a greater chance of being related to massive nickel sulphides.
Drill hole DDRDD0008 is planned to reach a depth of 350m.

| Aspects of the determination of mineralisationthat are Material to the Public Report.In cases where 'industry standard' work hasbeen done this would be relatively simple (eg'reverse circulation drilling was used to obtain1 m samples from which 3 kg was pulverised toproduce a 30 g charge for fire assay'). In othercases more explanation may be required, suchas where there is coarse gold that has inherentsampling problems. Unusual commodities ormineralisation types (eg submarine nodules)maywarrantdisclosureofdetailedinformation. | Diamond Core Sampling: Core is drilled with HQ and NQ2 size andsampled as half core to produce a bulk sample for analysis. Intervalsvary from 0.3 – 1m maximum and are selected with an emphasis ongeological control. | ||||||
| Assays are completed at Intertek Genalysis Laboratories in Perth.Samples are sent to Intertek where they are crushed to 6 mm andthen pulverised to 75 microns. A 30 g charge of the sample is fireassayed for gold, platinum and palladium. The detection range forgold is 1 – 2000 ppbAu, and 0.5 – 2000 ppb for platinum andpalladium. This is believed to be an appropriate detection level forthese elements within this specific mineral environment. However,should Au, Pt or Pd levels reported exceed these levels an additionalassay method will be used to re‐test samples. | |||||||
| All other metals will be analysed using an acid digest and an ICPfinish. The sample is digested with nitric, hydrochloric, hydrofluoricand perchloric acids to effect as near to total solubility of the sampleas possible. The solution containing samples of interest, includingthose that need further review, will then be presented to an ICP‐OESfor the further quantification of the selected elements. | |||||||

| RC Sampling: RC samples are visually checked for recovery, moistureand contamination. Geological logging is completed at site withrepresentative RC chips stored in chip trays. | |||||||
| Measures taken to maximise sample recoveryand ensure representative nature of thesamples. | Diamond Core Sampling: Depths are checked against the depth onthe core blocks and rod counts are routinely carried out by thedrillers. Core loss was recorded by St George geologists andsampling intervals were not carried through core loss. | ||||||
| RC Sampling: Samples are normally collected using a cone and rifflesplitter. However, in this program, the multi‐purpose diamond andRC drill rig did not have an industry standard splitter attached. RCsamples were taken manually in the most representative way. If anysample returns any values that are anomalous, then a portable rifflesplitter will be utilised to select another representative sample forassaying from the bulk sample of RC chips retained by the Company. | |||||||
| Whether a relationship exists between samplerecovery and grade and whether sample biasmayhaveoccurredduetopreferentialloss/gain of fine/coarse material. | To date, no detailed analysis to determine the relationship betweensample recovery and grade has been undertaken for this drillprogram.

| Dataaggregationmethods | InreportingExplorationResults,weightingaveragingtechniques,maximumand/orminimum grade truncations (e.g. cutting ofhigh grades) and cut‐off grades are usuallyMaterial and should be stated. | No top‐cuts have been applied. A nominal 0.15% Ni lower cut‐off isapplied unless otherwise indicated. | |||||
| Where aggregated intercepts incorporate shortlengthsofhighgraderesultsandlongerlengths of low grade results, the procedureused for such aggregation should be stated andsome typical examples of such aggregationsshould be shown in detail. | High grade massive sulphide intervals internal to broader zones ofsulphide mineralisation are reported as included intervals. | ||||||
| The assumptions used for any reporting ofmetal equivalent values should be clearlystated. | No metal equivalent values are used for reporting explorationresults. | ||||||
| Relationshipbetweenmineralisation | These relationships are particularly importantin the reporting of exploration results. | The geometry of the mineralisation is not yet known due toinsufficient deep drilling in the targeted area. | |||||
| widths andinterceptlengths | If the geometry of the mineralisation withrespect to the drill hole angle is known, itsnature should be reported. If it is not knownand only the down hole lengths are reported,there should be a clear statement to this effect(e.g.'downholelength,truewidthnotknown'). | ||||||
| Diagrams | Appropriate maps and sections (with scales)andtabulationsofinterceptsshouldbeincluded for any significant discovery beingreported. These should include, but not belimited to a plane view of drill hole collarlocations and appropriate sectional views. | Maps will be included with any announcement of any significantdiscovery, following review of assay results from the drillingprogramme. |
