Star Minerals Limited (ASX: SMS, “the Company” or “Star Minerals”) is pleased to advise results are now available for a rock chip campaign completed in late 2023 at the West Bryah Project. Samples were collected during a reconnaissance trip by experienced SMS geologists. The aim was to evaluate the Project for prospectivity for gold deposits similar to that defined by Metal Bank (ASX:MBK) at the Livingstone Project, 30km west of the Dimble and Mount Padbury Prospects. Potential for pegmatite hosted lithium mineralisation within the Yarlarweelor Gneiss was reviewed as part of the trip, with evaluation of geology exposure.
HIGHLIGHTS
- Results for 19 Rock Chips at West Bryah Project support Historical Exploration Results at Mount Padbury Prospect and potential of Dimble Prospects.
- Best Rock Chip results include:
- 30.2 g/t Au and 2.1% Cu in sample SMRK055 from Dimble East.
- 12.7 g/t Au in sample SMRK062 from Mount Padbury.
- 11.1 g/t Au in sample SMRK061 and 6.83 g/t Au in sample SMRK059 from West Dimble 4.
- 7.97 g/t Au in sample SMRK070 from Dimble West.
- Mount Padbury reconnaissance checks historical drilling by Lachlan Resources in 19971 that returned multiple significant gold intercepts in RAB and RC drilling, including down hole intercepts of:
- 12m at 5.66 g/t Au from 0m in RAB hole MPRB015, including 1m at 59.1 g/t Au from 7m;
- 19m at 2.68 g/t Au from 0m in RAB hole MPRB001, including 1m at 6.14 g/t Au from 4m and including 2m at 17.0 g/t Au from 8m;
- 9m at 1.35 g/t Au from 22m in RAB hole MPRB014;
- 4m at 2.69 g/t Au from 35m in RC hole MPRC0002, including 1m at 7.43 g/t Au from 35m;
- 2m at 2.42 g/t Au from 11m and 1m at 1.16 g/t Au from 20m in RC hole MPRC0004;
- 3m at 1.66 g/t Au from 5m in RC hole MPRC0007; and
- 1m at 8.04 g/t Au from 27m in hole MPRC0008
- Historical drilling and sampling and recent surface sampling highlight potential for West Bryah Project to host gold deposits similar to the Livingstone Project deposits 30km to the west owned by Metal Bank Limited.
Star Minerals’ Chair, Ian Stuart commented:
“Reconnaissance work at the West Bryah continues to deliver significant high-grade gold in surface samples, validating the historical dataset compiled by the Company.
Star Minerals are focussed on building understanding of the controls on gold mineralisation at the Project to get ready for drill testing of the multiple targets at the Dimble and Mount Padbury areas.
We are confident that well designed programs of modern exploration will unveil further targets at the Project, with all commodities under consideration for targeting to compliment the numerous gold Prospects already present”.
The location of the West Bryah Project is shown in the geology plan for the Bryah Basin region, Figure 1 below. The plan shows the extent of Narracoota Formation and Wilthorpe Formation present in the West Bryah Project, both geology units that host significant gold and/or VMS deposits further north and east in the Bryah Basin.

West Bryah Gold Prospects Overview
The Dimble Prospects and Mount Padbury Prospect were the main areas of interest during the field trip. Figure 2 below shows the location of the gold prospects at the Project, plus the Yarlarweelor Gneiss complex, considered prospective for lithium mineralisation. The Dimble Prospects have historical drilling from the 1970s – 1980s, in addition to multiple generations of soil and surface sampling with digital compilation in progress for all historical data. Rock chip results and a high density of early 1900s workings demonstrate the high grade nature of the gold mineralisation at Dimble. There is good exposure of geology throughout the Dimble Area which extends for 9km strike in the east to west direction, and 2.5km in the north – south direction.

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.
