Underexplored region containing recent world‐class gold discoveries at Tropicana (+8MozAu) and Gruyere (+6MozAu)
ST GEORGE READY TO DRILL AT EAST LAVERTON
St George Mining Limited (ASX: SGQ ) (‘St George Mining’ or ‘the Company’) is pleased to announce a major drill programme at its 100% owned East Laverton Project in Western Australia. The drill rig is mobilising to site today with drilling expected to commence by this Saturday.
This reverse circulation (RC) drill programme will primarily focus on the pipeline of gold targets established across the three underexplored greenstone belts at East Laverton. Targets on all three major greenstone belts will be drilled with over 5,000m of drilling planned.
The drill programme will also include the drill testing of the highly conductive DHEM plate at the Windsor nickel sulphide prospect. At 210,000 Siemens, this is the most conductive nickel sulphide target identified at the East Laverton Project to date.
St George Mining Executive Chairman, John Prineas said:
“Our technical team, in conjunction with our external experts – Dr Walter Witt and Dr Jon Hronsky, have dedicated considerable time in developing the pipeline of gold targets across the East Laverton Project. We are pleased to commence drilling of these targets which have the potential for a significant gold discovery.
“The drilling of the extremely powerful EM conductor at Windsor has been much anticipated, and I’m happy to say that this outstanding nickel sulphide target will be the first to be drilled in this programme.
“With ongoing major drill programmes at our East Laverton and Mt Alexander Projects, it’s a very exciting time for our shareholders.“

WINDSOR – HIGHLY CONDUCTIVE EM TARGET
Past drilling by St George at the Windsor nickel sulphide prospect has resulted in numerous disseminated nickel sulphide intersections within channel facies komatiites, indicating an attractive exploration area for a massive nickel sulphide deposit.
Drill hole WINDD004 was drilled by St George to test the highly conductive DHEM plate WINRC016_v1 (210,469 Siemens) at Windsor. There was no conductive material in the drill core of WINDD004 capable of providing the extremely high EM response that was modelled for DHEM plate WINRC016_v1 . The DHEM survey data from WINDD004 identified a strong off‐hole EM anomaly about 5 metres to the north of WINDD004, indicating that WINDD004 came close to testing the conductive source but did not intersect it.
Newexco has completed further interpretation of the DHEM data from WINDD004 and WINRC016 resulting in a new DHEM plate – WINDD004_v1. This plate is modelled with a very high conductivity response, has dimensions of 50m x 10m and is situated 95m below surface.
Figure 1 is a cross section of drilling at Windsor which illustrates the location of DHEM plate WINDD004_v1 on the western contact of the Windsor ultramafic, a favourable setting for potential nickel sulphide mineralisation.

Nickel sulphide enrichment was identified in WINDD004 between 85m to 138m downhole with nickel values up to 1.05%Ni. The presence of nickel sulphide mineralisation adjacent to the DHEM plate supports the potential for this highly conductive target to represent massive nickel sulphides.
MAJOR GOLD DRILL PROGRAMME
The East Laverton Project is located near the eastern margin of the North Eastern Goldfields, an area that remains underexplored and where two of the most recent large greenfields gold discoveries in Australia ‐ the +8MozAu Tropicana deposit and the +6MozAu Gruyere deposit – are also located.
Historical drilling, as well as recent nickel‐focused drilling by St George, has identified widespread gold anomalism on all three main greenstone belts at the East Laverton Project. This gold anomalism has the potential to be associated with larger gold systems that could host significant gold deposits.
A pipeline of prospective gold targets has been identified by our technical team, working in conjunction with external experts Dr Walter Witt and Dr Jon Hronsky. Drill holes have been planned for these targets and prioritised for drilling.
The gold drill programme was scheduled to commence at East Laverton in March 2017 with 2,000m of planned drilling. The start of the drill programme was delayed due to unseasonal heavy rains in the North Eastern Goldfields that caused numerous road closures by local shires, and prevented access to our East Laverton Project. The delay in the start of the programme has allowed further drill targets to be finalised and added to the programme, expanding it to over 5,000m of planned drilling.
Figure 2 illustrates the priority gold targets situated across the three main greenstone belts at East Laverton.

Cambridge Gold Prospect:
The first prospect to be drilled will be Cambridge on the Stella Range Belt. Figure 3 illustrates the four target areas at Cambridge that will be drilled in this programme.
Target A – drilling here will test for gold mineralisation in an embayment on the western contact of the large Cambridge ultramafic body. This is a favourable structural area with its gold prospectivity corroborated by the presence of gold soil anomalies.
Target B – this area is a section of the untested eastern contact of the ultramafic body where rheological contrast is at its greatest at a favourable fault bend location.

Target C – this area encompasses the intersection of a fold axis and a reactive Fe‐rich unit, with possibly dolerite mafic units. There is extensive anomalous Cu and Mo in soil samples for this area. Anomalous Au intervals were encountered in historical shallow drilling that includes 6m @ 0.41ppmAu from 15m in SRAB129, reflecting supergene gold.
Target D – this is a bulls‐eye magnetic anomaly that is possibly an intrusion or folded BIF with extensive anomalous Cu and Mo in soil samples. Anomalous Au intervals in historical shallow drilling include 6m @ 0.74ppmAu from 6m in SRAB170, reflecting supergene gold.
Other Gold Prospects to be Drilled:
In addition to Cambridge, drilling is also planned in this programme for the prospects at Cambridge North, Desert Dragon, Bristol and Athena.
Further details of the drilling scheduled for these targets will be announced shortly.

| Parties | by WMC Resources in the early 1990s. This drilling was relatively | |
| shallow, mostly less than 100m. | ||
| The historical drilling along the Minigwal belt defined linear zones of | ||
| anomalous gold and copper in the regolith that extend over 1,300m | ||
| and are open to the south towards the Ascalon target. | ||
| The Bristol gold target is situated along the Central Belt within the | ||
| East Laverton Project. Widespread anomalous gold (>0.5g/t Au) was | ||
| encountered over a 1km strike length from shallow drilling in this | ||
| area completed in the 1990s by previous exploration. | ||
| The average hole‐depth for the past drilling at Bristol was | ||
| approximately 40m and identified anomalous gold in the lower | ||
| regolith. Significantly, gold anomalism in seven of the eight drill | ||
| holes occurs at the end of hole. The continuation of this gold | ||
| mineralisation, or the presence of bedrock gold mineralisation, has | ||
| never been tested. | ||
| The gold anomalism is situated on the contact of the Bristol | ||
| ultramafics/mafics with granites, as defined by a distinct magnetic | ||
| and gravity gradient. This is a favourable setting for gold | ||
| mineralisation. | ||
| Savanna Mineral Resources Pty Ltd completed a number of shallow | ||
| drill programmes across the Stella Range Belt during the 1990’s | ||
| including the series of drill holes designated SRAB001 to 176. | ||
| Anomalous gold was identified in numerous drill holes, interpreted | ||
| to be supergene gold. The presence of bedrock gold mineralisation | ||
| at St George’s gold targets has never been tested. | ||
| Nickel Exploration: | ||
| In 2012, BHP Billiton Nickel West Pty Ltd (Nickel West) completed a | ||
| reconnaissance RC (reverse circulation) drilling programme at the | ||
| East Laverton Property as part of the Project Dragon farm‐in | ||
| arrangement between Nickel West and the Company. That farm‐in | ||
| arrangement has been terminated. The drilling programme | ||
| comprised 35 RC holes for 8,560m drilled. | ||
| The results from the Nickel West drilling programme were reported | ||
| by the Company in its ASX Release dated 25 October 2012 “Drill | ||

| Prior to the Project Dragon drilling programme, there was no | ||
| systematic exploration for nickel sulphides at the East Laverton | ||
| Property. Historical exploration in the region was dominated by | ||
| shallow RAB and aircore drilling, much of which had been | ||
| incompletely sampled, assayed, and logged. This early work was | ||
| focused on gold rather than nickel sulphide exploration. | ||
