Australian focussed explorer, GWR Group Limited (ASX: GWR) (“GWR” or “the Company”) is pleased to provide an exploration update for the Wiluna West Gold Project in Western Australia (Figure 1).
Following the execution of a Memorandum of Understanding (“MoU”) with Blackham Resources Limited (“Blackham”) (ASX: BLK) for the potential treatment of deposits at Wiluna West, the Company has developed a two pronged strategy;
-
Assessing its existing gold prospects that have the potential to be near term mining opportunities and generate positive cash flow, and
-
Undertaking exploration activities designed to identify potential for “company making” gold deposits.
Golden Monarch Near Term Mining Opportunity
At Golden Monarch, previous shallow drilling identified a Mineral Resource (JORC 2004, Indicated Resource of 46,000 tonnes at 3.5g/t Au and Inferred Resource of 685,000 tonnes at 2.3 g/t Au) over a strike length of 1.5 km; ( refer Table 1- Wiluna West Gold Project Gold Resource Estimate). Studies of the mineralisation over a strike length of 500m have identified two south plunging shoots within the deposit that have a combined length of approximately 300m. The northern shoot has been tested to approximately 45m in depth and the southern to approximately 75m in vertical depth (Figure 2).
The current drilling program aims to define these shoots down to a 120 m vertical depth and further test near surface mineralisation as the next stage in determining the economic feasibility of the project. The Company will be testing down plunge extensions to intersections including;
-
8m at 3.64 g/t Au from 68 m in WWRC045
-
13m at 3.57 g/t Au from 83 m in WWRC056
-
10m at 3.62 g/t Au from 51 m in WWRC060
-
10m at 2.95 g/t Au from 70 m in JFRC08
-
6m at 4.93 g/t Au from 71 m in JFRC01
-
3m at 20.77 g/t Au from 38 m in JRC153, including 1 m at 54.3 g/t Au

GWR Group Ltd 97 Outram Street ABN 54 102 622 051 West Perth WA 6005
The RC drilling program comprising 21 holes for 1,650 metres will commence in mid-July and take approximately two weeks to complete. Results will be received in August with an updated Mineral Resource anticipated for September 2017.
Emu / Eagle RC Drilling
The recent review identified the Eagle (JORC2004 Inferred Mineral Resource Estimate of 489,000 tonnes at 2.4g/t Au for 37,800oz at a 1g/t cut off) and Emu (JORC2004 Inferred Mineral Resource Estimate 371,000 tonnes at 2.4 g/t Au for 28,700oz at a 1g/t cut off); as the next most attractive for short term production opportunities via the MoU with Blackham (refer Table 1 Wiluna West Gold Project Resource Estimate).
Approval has been received for 2,560 metres of RC drilling at Emu and Eagle of which 1,235m is considered as high priority. This program is planned to be undertaken towards the end of Q3 2017, subject to rig availability.

Regional Exploration Program & Results: Introducing “ The Blob”
Over the last six months the Company has completed a comprehensive mapping and geochemical soil sampling program over the Bowerbird prospect and over a 4 km strike length of the Joyners Shear Zone between the Comedy King and Emu prospects (Figure 1). This work has included:
-
Re-interpretation of the high-quality aerial magnetic data by Southern Geoscience Consultants (“SGC”), which was acquired as part of the iron ore project;
-
1:1000 scale detailed geological mapping over a strike length of 4 km;
-
Orientation geochemical soil sampling program;
-
Collection of 1,663 soil samples screened to -2.8 mm and +0.5 mm on a 100 m by 25 m spacing;
-
Collection of 260 rock chip samples; and
-
Survey of historical gold exploration drill hole collars with 1,000 targeted and 300 located.
The re-interpretation of the aerial magnetic data by SGC identified several structural targets and this, combined with previous drilling and historical geochemical sampling, highlighted the Bowerbird prospect and the area between the Comedy King and Emu prospects as high priority target areas.
Orientation geochemical soil sampling was undertaken and this assessment involved testing different size fractions to determine the optimal size for ongoing sampling and targeting. During this study, it was determined that the minus 2.8 mm to plus 0.5 mm fraction gave the best response at Wiluna West for gold.
The geochemical soil sampling identified a number of anomalies (>10 ppb Au) that justify following up including 4 samples of >1000 ppb Au, including one sample of 6,612 ppb (6.6 g/t) and the Blob and Bowerbird anomalies.
The Blob is a large +10 ppb Au anomaly measuring at least 400 m x 400 m and at +30 ppb: 300 m by 200 m (Figure 3); which is also anomalous in arsenic. As Figure 3 shows, The Blob anomaly is significantly larger than that expressed by the Eagle deposit (JORC 2004 Inferred Resource of 489,000 tonnes at 2.4 g/t Au) and occurs at the junction of a major north–south trending shear zone and a cross cutting northeast trending fault. It is also located in a zone of demagnetisation. No drilling targeting gold mineralisation has ever been undertaken over the peak of the anomaly.

Geochemical soil sampling over the Bowerbird area identified a strong +10 ppb Au anomaly over a strike length of 1.2 km. This contained a higher grade core of +30 ppb Au over a 1.0 km length with values of up to 136.9 ppb Au. The anomaly also overlays an interpreted dilatational feature identified by SGC.
A POW has recently been lodged with DMP to undertake an aircore (“AC”) drilling program over the Bowerbird and The Blob prospects, with drilling planned for the latter half of 2017 once approvals have been received
Commentary
GWR’s Chief Executive Officer, Craig Ferrier, said “ A much clearer development pathway at Wiluna West based on minimal capital outlay, has allowed us to significantly change the way that we look at the current deposits and prospects.
“Our focus is firmly on defining Mineral Resources that meet the criteria for mining and processing through the Wiluna Gold Plant. This current program at Golden Monarch has the potential to meaningfully add to the resource base.”

| Sampling techniques |
The soil samples were collected upon a 100 m by 25 m spacing located with a hand held GPS. The samples were collected at a depth of approximately 0.2 m using a pick or shovel and screened to minus 2.8 mm in the field to obtain a sample of approximately 200 g. The field samples were then screened and the minus 2.8 mm plus 0.5 mm fraction was weighed and the approximate 100 g sample submit to Intertek Genalysis laboratories in Perth. At Intertek Genalysis the samples were dried, pulverised then subject to aqua regia digest and read using ICP-MS, for the elements and detection limits as listed below; |
|
| Element | Detection Limit |
|
| Au | 0.1 ppb | |
| As | 1 ppm | |
