Warriedar Resources Limited (ASX: WA8) (Warriedar or the Company) is pleased to report on assay results received for the five (5) holes drilled at the Austin deposit, part of the ongoing Reverse Circulation (RC) drilling program at its Golden Range Project in the Murchison province of Western Australia.
HIGHLIGHTS:
- RC drilling results at the Austin deposit (Golden Range Project), located 4km southwest of the Golden Grove Cu-Zn-Pb-Ag-Au deposit, intersected polymetallic sulphide mineralisation.
- The Austin polymetallic system, open at depth and plunging south, sits within an interpreted Volcanogenic Massive Sulphide (VMS) horizon.
- Robust extensional intercepts returned including 20m @ 1.98g/t Au, 7.2g/t Ag, 844ppm Pb from 160m; and 8m @ 1.04g/t Au, 19.5 g/t Ag, 0.54% Pb from 144m.
- Historic drilling at Austin (gold was the focus but multi-element assays were taken) returned 30m @ 3.31 g/t Au, 29 g/t Ag, 0.62% Pb from 127m, including 2m @ 7.07 g/t Au, 140 g/t Ag, 1% Pb and 2m @ 3.15 g/t Au, 54 g/t Ag, 2.5% Pb.
- Five (5) holes for 1,086m have been drilled at Austin in this campaign, with target depth not achieved for three (3) of those holes; follow-up diamond tails and surface and downhole Electromagnetic (EM) surveying is planned for Q3, chasing high grade feeder zones.
The holes were planned to test for depth extensions to the gold mineralisation lying under the existing shallow pit (previously mined in 2014 for oxide gold mineralisation), and to investigate the potential for the Austin deposit to be polymetallic. RC holes drilled in 2020 and 2021 by the previous owner had intersected high grade gold and silver with sub-economic base metals (see Table 2). This was the first time that multi-elements were assayed for the Austin deposit.
The Warriedar team reviewed the historical data and carried out a geological and geochemical interpretation, indicating the Austin primary polymetallic sulphide mineralisation is hosted within a felsic-intermediate unit at the contact with an overlying mafic-ultramafic unit.
Three of the five holes drilled at Austin in this campaign failed to reach target depth due to excessive water. These holes are planned to be diamond tailed in the Q3 drilling program. Two holes were successful in reaching target depth.
Key intervals returned from these two holes include (refer Table 1, and Figures 3 and 4):
- 8m @ 1.04 g/t Au, 19.5 g/t Ag, 0.54% Pb from 144m (AURC087); including
- 4m @ 0.88 g/t Au, 27 g/t Ag and 1.02% Pb from 144m (AURC087);
- 20m @ 1.98 g/t Au, 7.2 g/t Ag, 844ppm Pb from 160m (AURC086).
The Ag and Pb assay results confirm the Warriedar model that the Austin deposit is a polymetallic deposit with significant base metal exploration potential. Currently, the mineralisation is open in both the north and south direction (along what is termed the host horizon, a more conductive unit mapped well in the Airborne Electromagnetic (EM) and Gradient Array Induced Polarization (GAIP) data; see Figure 2). The existing drilling suggests the system is plunging to the south, however further drilling is required to better understand the scale and geometry of the deposit, and where, if any, higher grade VMS feeder zones exist within the host horizon.
The Yalgoo Singleton Greenstone belt that underlies the Warriedar tenements, hosts several Volcanogenic Massive Sulphide (VMS) deposits, the most significant being the Cu-Zn-Pb-Ag-Au Golden Grove cluster of mines, located approximately 4kms to the east of Austin (see Figure 1). To the south in the same belt is Capricorn Metals’ (ASX: CMM) Mt Gibson Gold Project, believed to have originally been a Au-Cu-Zn rich VMS deposit that has been overprinted by a later hydrothermal gold mineralising event. To the north in the same belt are the Venture Minerals (ASX: VMS) VMS prospects (see locations in Figure 1).
VMS deposits typically occur in clusters, as readily demonstrated at the adjacent Golden Grove cluster. Encouragingly, there is a weak bedrock conductor in 2014 Airborne EM data approximately 1.2km south of the historical Austin pit, within the same host horizon. Ground and downhole EM are the only effective EM configurations for detecting Golden Grove style mineralisation1, and ground EM is planned to be undertaken over the conductor south of Austin during H2 2023.

- RXDD122: 0.95m @ 13.50 g/t Au from 204.44m
- §These results further demonstrate the continuity of high- grade gold mineralisation along the Youanmi greenstone belt belt, and the potential for resource growth both at depth and along-strike, with discovery potential to the south
- 35,000m Step-up drill campaign well underway with the plan to bring forward ounces and increase the mine plan
The program focused on converting Inferred stopes at Pollard, United North and Youanmi Main to higher confidence Indicated classification and providing material for metallurgical testing for the upcoming Definitive Feasibility Study (DFS) – on track for H2 CY25.
This final consignment of diamond assay results are the fourth batch of assays results returned from the drill program and have been entirely drilled from the Pollard, Youanmi and United North areas (Figure 1).
Rox Resources’ Chief Executive Officer, Phillip Wilding, commented:
“It’s pleasing to round out the 11,000m RD and DD drilling program with another batch of excellent intercepts.
“More importantly, the program has significantly improved our knowledge of the high grade and underexplored Youanmi ore system, and shown that mineralisation remains open at depth.
“Next steps are to convert Inferred areas of the Resource to the higher confidence Indicated classification, and finalise key intercepts of sample material for metallurgical test work to feed into the Youanmi DFS.
“We are excited to have commenced the 35,000m Step-up program to potentially bring forward ounces in the mine plan and significantly increase the size of the Pollard ore zone.”
Youanmi Major Growth Drill program
Resource drilling has focused on converting selected Inferred stopes in the current Mineral Resource of 16.2Mt at 4.4g/t Au for 2.3Moz (Indicated: 10.7Mt at 4.5g/t Au for 1.6 Moz : Inferred 5.5Mt at 4.2g/t Au for 0.7 Moz) 1 to higher confidence Indicated classification at Pollard, United North and Youanmi Main as shown in plan on Figure 1. The drilling has also provided both sample material for metallurgical testing and valuable geological data for the pending Definitive Feasibility Study (“DFS”) planned for second half of 2025.

Outside of the immediate resource area, drilling was also conducted on near-mine exploration and focused on the Youanmi South prospect area, or Paddy’s Lode, first reporting high-grade intercepts in 20232. The drilling at Paddy’s has complimented the Company’s exploration strategy moving south along the Main Lode Shear Zone (MLSZ) and adding additional gold ounces to the Resource. Youanmi South has the potential to grow the Resource above the 103kozpa Production Target outlined in the recently completed Pre-Feasibility Study (“PFS”)3.

Drilling Commenced at Viani in Fiji
HIGHLIGHTS
- The Phase 1, three-hole diamond drilling program has commenced at the Viani Project, Fiji and will test for extensions to the quartz vein gold mineralisation at depth.
- Phase 1 is expected to be completed in early 2025, with plans for additional drilling under the same program dependent on the initial results
- The Viani Project (SPL1513) covers an area of approximately 200km2 and is largely underexplored.
- At the Dakuniba prospect within Viani, low sulphidation epithermal high-grade gold mineralisation has been mapped over >3km strike length.
- Diamond drilling completed by Japan International Cooperation Agency (JICA) in 1995 to 1997 intersected high-grade gold in low sulphidation epithermal quartz veins, including 0.6m @ 27.6 g/t Au.
Alice Queen’s Managing Director, Andrew Buxton said,
With drilling underway, Alice Queen is positioned to test the epithermal gold-style mineralisation identified in historic drilling at the Viani Project. Weather permitting, we anticipate completing the Phase 1, three-hole diamond drilling program in early 2025. Following this, our exploration team will mobilise the drill rig to the Sabeto Project in Fiji to maintain the momentum of this campaign. To deliver timely results to shareholders, we intend to accelerate the analysis of the drill core at ALS Brisbane.”

Details
Geology
The geology of the Viani Project (SPL 1513) comprises olivine basalts and volcaniclastics of the Natewa Volcanic Group which are intruded by andesite sills and dykes. In the 1940s, gold mineralisation was found by local prospectors near the village of Dakuniba. At Dakuniba, low sulphidation style epithermal gold occurs in quartz veins, and silicified rocks along a 3km long NE trending zone.
In 1995-1997, Japan International Cooperation Agency (JICA) drilled six diamond holes at Dakuniba and intersected high-grade gold in chalcedonic, crustiform, colloform banded quartz veins at depths of 50m to 100m below surface (i.e. MJVFV-5 intersected 2.2m @ 11.3 g/t Au, incl 0.6m @ 27.6 g/t Au at 121m downhole). This high-grade gold mineralisation is open in all directions.
Proposed Drill program
The initial Phase 1 drill program at Viani (see Table 1) will comprise three diamond drillholes designed to test continuity to the epithermal gold mineralisation previously intersected in JICA drillhole MJVFV- 5 (2.2m @ 11.3 g/t Au) (see Figure 2). The drilling will test for extensions to the gold mineralisation at depth and along strike.
