Commenting on the drilling, Bryah CEO Ashley Jones said: “These excellent drill results follow our other news flow, being the updated manganese resource and the granting of the mining leases. All the manganese JORC resources are now on granted mining leases. The August drilling results continue to expand the mineralisation at Brumby Creek West and Redrum. Our grades reported are using cutoffs higher than many other ASX reported resource grades, which should give us the competitive edge when it comes to mining”.
The Bryah Basin project area is located approximately 100km north of the town of Meekatharra in Western Australia. The Company’s tenements and manganese mineral rights cover 1,135km² over parts of the western Bryah Basin. Figure 1 shows the Manganese Joint Venture tenement package, with prospects and an existing manganese Mineral Resource.1
The August 2023 drill program covered 95 holes for 2938 metres. The prospects drilled were Brumby Creek West, Epona, Redrum, Black Hill North and Gold Trip. The best drill intersections continued to come from the extensional drilling around the resources at Brumby Creek and Redrum.

Brumby Creek West
Drilling in August continued to follow the shallow manganese mineralisation southwards. The mineralisation appears to be bifurcating with excellent results on the western side becoming prominent. Grade though is still excellent, with the best results of:
- 6m at 24.4% Mn from 19m in hole BBRC0249
- 13m at 22.7% Mn from 15m in hole BBRC0241
- 4m at 22.05% Mn from 28m in hole BBRC0251

BYH:AU
High grade Assay Results Continue at Youanmi
- The latest batch of assays have been received from the 11,000m drilling program (both diamond core and reverse circulation) at the high gold-grade Youanmi Gold Project, located centrally in Western Australia’s prolific gold fields
- The recently-completed infill/exploration program aimed to improve resource confidence and open up corridors for resource growth; to underpin the Definitive Feasibility Study (DFS), and, additionally, provide sample material for ongoing metallurgical optimisation test-work for the DFS program
- Latest highlights from the program include:
- RXDD131: 4.38m @ 19.07 g/t Au from 387.98m,
- incl. 1.73m @ 41.43 g/t Au from 389.96m
- RXDD119: 4.56m @ 14.60 g/t Au from 220.64m
- RXDD115: 2.99m @ 21.11 g/t Au from 249.88m
- RXDD119: 4.0m @ 7.37 g/t Au from 162.0m
- RXDD132: 7.19m @ 3.90 g/t Au from 263.61m
- RXDD133: 2.83m @ 6.53 g/t Au from 431.00m
- RXDD128: 3.82m @ 4.51 g/t Au from 364.59m,
- incl. 1.73m @ 8.22 g/t Au from 364.59m
- incl. 1.73m @ 8.22 g/t Au from 364.59m
- 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.
