• These outstanding results represent a significant game changer for GWR as it transitions from explorer to gold producer.
• The Golden Monarch deposit targeted as the start-up mine via the Binding Heads of Agreement executed with Blackham Resources ("BLK") whereby BLK will form a joint venture to mine and mill Wiluna West gold deposits (refer to GWR, ASX announcement dated 23rd November 2018).
• BLK own the Wiluna gold mill located 40km to the north east of the Wiluna West Gold project which is earmarked under the Binding HoA for processing.
• Latest drilling shows the potential to provide the Wiluna Mill with an additional feed source.
• Updated resource models will now be prepared for all three deposits.
• Mining approvals are largely in place for Golden Monarch.
• These exciting results will help underpin studies into the viability of all three deposits and further processing strategies.
GWR Group Limited (ASX: GWR) ("GWR" or "the Company") is pleased to announce that it has received the final assay results from the 72 reverse circulation ("RC") drill holes for 3,918 m recently completed at the Golden Monarch, Emu and Eagle deposits at its Wiluna West Gold Project.
The Wiluna West Gold Project contains a combined Mineral Resource estimate of 3.5 million tonnes at 2.3 g/t Au for 254,000 oz (refer to ASX announcement dated 31st October 2017). The project is locatedapproximately 40 km south west of the Blackham Resources Limited ("BLK") (ASX:BLK)) Matilda / Wiluna Gold Operation which includes a gold processing and treatment plant (Figure 1). The gold mineralisation at the Golden Monarch, Eagle and Emu deposits is within the regional Joyners Find shear zone and is hosted within steep westerly dipping banded iron formation units ("BIF"). All of the recent and most of the historical drilling is on an azimuth of 0900 inclined at -600 which is approximately perpendicular to the mineralisation.
Recently appointed GWR General Manager Adrian Costello who was appointed because of his extensive gold mining experience said: "The Company is excited by the very solid drilling results achieved at Wiluna West".
"GWR Group is in the process of transitioning from an explorer to a Gold producer and the results of this recent drilling adds more support to GWR's strategy of moving the Company into production," Mr Costello said.
Binding Heads of Agreement with Blackham a low capex route to gold producer
In November 2018 GWR executed a Binding Heads of Agreement ("HoA") with BLK for the establishment of a joint venture for the development, mining and processing of gold mineralisation from the Wiluna West Gold Project (refer to ASX announcement dated 23rd November 2018).
Under the terms of the HoA GWR is responsible for drilling deposits to JORC (2012) Indicated category, if successful it can nominate the deposit as a Proposed Qualifying Deposit and BLK will conduct feasibility studies and if positive, undertake mining, transport, and processing of the deposit.
The recent RC drilling targeted Golden Monarch, Eagle and Emu as Proposed Qualifying Deposits.
Golden Monarch
The Golden Monarch deposit contains a combined Mineral Resource estimate of 747,000 tonnes at 2.2 g/t Au for 52,400 oz (refer to ASX announcement 31st October 2017 and Table 1). A total of 37 RC holes for a total of 1,636 m was recently completed over a strike length of 1,040 m (Figure 3). There is a substantial amount of previous drilling (340 holes for 14,411m) and the recent program was designed to infill the overall drill hole spacing to a minimum of 20 m north and 10 m east.
All significant intercepts from the recent RC drilling program are summarised in Table 2. Significant intercepts include;
o WGRC0054, 7 m @ 12.0 g/t Au from 28 m, including 1 m @ 72.0 g/t Au
o WGRC0055, 4 m @ 4.4 g/t Au from 50 m, including 1 m @ 13.6 g/t Au
o WGRC0061, 7 m @ 11.8g/t Au from 36 m, including 1 m @ 72.3 g/t Au
o WGRC0073, 7 m @ 8.3 g/t Au from 18 m, including 1 m @ 38.1 g/t Au
The shallow and robust nature of these intercepts confirms the potential of Golden Monarch
The results from the recent drilling are being compiled and it is intended to submit Golden Monarch to BLK as a Proposed Qualifying Deposit under the terms of the Binding HoA.
In addition to the recently completed drilling GWR has already commenced permitting / approvals process which is somewhat streamlined as it is largely within clearing permits and Mining Approvals already granted as part of the Wiluna West Iron Project.
Emu
The Emu prospect contains a JORC (2004) Inferred Mineral Resource estimate of 371,000 tonnes at 2.4 g/t Au for 28,700 oz (refer to ASX announcement dated 14th June 2010 and Table 1). A total of 17
RC drill holes for 1,124 meters was recently completed over a strike length of 440 m testing a mineralised BIF. Figure 4 shows the collar positions of drilling to date and Figure 5 provides a representative cross section of the mineralisation. The recently completed drilling has infilled the pattern to a nominal 40 m north and 15 m east spacing.
All significant intercepts are listed in Table 2 and include;
o WGRC0092, 5 m @ 15.0 g/t Au from 45 m, including 1 m @ 69.4 g/t Au
o WGRC0096, 12 m @ 7.3 g/t Au from 48 m, including 3 m @ 25.3 g/t Au
o WGRC0101, 8 m @ 11.1 g/t Au from 53 m, including 3 m @ 25.0 g/t Au
o WGRC0105, 10m @ 2.6 g/t Au from 47 m
The high grade intercepts achieved in some holes was unexpected and approximately 50% of recent drilling is outside of the current Resource model. Detailed geological mapping, plus review of optical televiewer data acquired from down hole surveys is planned to investigate potential structural controls to the high grade mineralisation. It is also planned to update the Resource model incorporating the recent drilling to JORC (2012)
Eagle
The Eagle prospect contains a JORC (2004) Inferred Mineral Resource estimate of 489,000 tonnes at 2.4 g/t Au for 37,800 oz (refer to ASX announcement dated 14th June 2010 and Table 1). A total of 18 RC drill holes for 1,158 m was recently completed over a strike length of 240 m testing a mineralised BIF. Figure 6 shows the collar positions of drilling to date and Figure 7 provides a representative cross section of the mineralisation. The recently completed drilling has infilled the pattern to a nominal 20 m north and 20 m east spacing.
All significant intercepts are listed in Table 2 and include;
o WGRC0083, 12 m @ 2.1 g/t Au from 43 m
o WGRC0086, 6 m @ 3.7 g/t Au from 10 m
o WGRC0089, 7 m @ 3.0 g/t Au from 50 m
o WGRC0108, 6 m @ 4.00 g/t Au from 118 m
o WGRC0114, 5 m @ 9.7 g/t Au from 54 m, including 2 m @ 21.8 g/t Au
It is now planned to update the existing JORC (2004) model to JORC (2012) incorporating the recent drilling results.
Next steps
The following activities are planned;
o continue Golden Monarch feasibility studies
o Complete permitting and mining approvals for Golden Monarch
o Compile Eagle and Emu data and update Resource models and plan work required to allow submission to BLK as Proposed Qualifying Deposits
o Undertake a comprehensive review of the entire project to prioritise targets for future work
