Odessa Minerals Limited (ASX:ODE) (“Odessa” or the “Company”) is pleased to provide a further update on the exploration program underway at its Yinnetharra Lithium Project at Lockier Range in the Gascoyne region of Western Australia.
Highlights:
- First assay results confirm fertility of Robinson Bore pegmatites to host lithium-bearing minerals
- >16,500m of pegmatites mapped at Robinson Bore
- First rock chip assays of pegmatites at Robinson Bore return up to:
- 1097ppm Li2O
- 10 other samples above 500ppm Li2O
- Highly-elevated key lithium-pegmatite pathfinders including:
- > 2000ppm Rb in four pegmatites
- 672ppm Cs
- 212ppm Ta
- 2970ppm Be
- Soil sampling complete - assay results pending
- Sampling in other pegmatite fields including Central Pegmatite Field, pending assay
Robinson Bore Lithium Pegmatite Targets
The Robinson Bore pegmatite field is one of four mapped pegmatite fields at the Lockier Range Project, located proximal to Delta Lithium’s Yinnetharra lithium discovery. Robinson Bore contains >16,500 metres of mapped pegmatites (Figure 1). Recent rock sampling results from pegmatites have demonstrated their fertility to host lithium-bearing minerals. Previous soil sampling results have shown extensive lithium anomalies over 4 x 2km.
Recent rock chip sampling aimed to identify highly fractionated and fertile pegmatites within the Robinson Bore pegmatite field through feldspar and mica multi-element analysis, as well as whole-rock pegmatite analysis. The Company has successfully identified a 2.5km-long northwest-trending corridor of fractionated pegmatites coincident with a lithium-in-soil anomaly (Figure 2). Peak Li2O in rock was 1097 ppm. A further 10 samples returned anomalous Li2O values above 500pm, with coincident elevated pathfinders of Cs-Ta-Be (Figure 3).
David Lenigas, Executive Director of Odessa, said: “Highly promising first assay results are in from our extensive rock chip and soil sampling programme at our Yinnetharra Lockier Range Project. The K/Rb ratios from some of our samples are showing that we are in or near to the sweet spot for lithium mineralisation and we are already seeing some strong lithium indicators coming through. The majority of more than 16km of mapped pegmatites at Robinson Bore sub-crop, with vast areas concealed by cover material. The Company is awaiting the assay results from a 100m x 100m infill soil sampling programme to identify the extent of the potential blind, fertile pegmatites. The soil sample results will be of particular importance at the northern end of the fractionation trend, where the most fractionated pegmatites have been discovered, but rarely outcrop.”

ODE: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.
