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:
- Assay results (Rock chip and soils) define standout DRILLING TARGETS for Lithium in Pegmatites
- Soil sampling defines coherent anomalous lithium-pegmatite trends:
- 248 soil samples return Li2O > 100 ppm
- 4km x 2km northwest-trending Li-Cs-Ta-Be-Rb-Bi anomaly at Robinson Bore coincident to the 16,500m of sub-cropping fractionated pegmatites
- 2.7km x 2km coherent Li-Cs-Ta-Be anomaly at the Eastern Pegmatite Field adjacent to the fertile Thirty Three Supersuite granite
- Highly-elevated key lithium-pegmatite pathfinders in rock chips including:
- peak Li2O result of 1911ppm
- 22 samples above 500ppm Li2O
- 5 samples above 100ppm Ta2O5 (Peak 259ppm)
- 18 samples above 100ppm Cs2O (Peak 712ppm)
- 9 samples above 100ppm BeO (Peak 8245ppm)
- 7 samples above 2000ppm Rb (Peak 2728ppm)
- Pegmatite Rock chip samples at Mt Yaragner show a westward fractionation trend with K/Rb ratios within feldspars <30
David Lenigas, Executive Director of Odessa, said: “Odessa’s exploration team have processed thousands of rock chip and soil samples from Lockier Range over the past 6 months and the results have now defined some exceptional lithium rich areas that will be targeted with our maiden drilling programme. The Company is actively engaging with Native Title Holders to complete the necessary access permissions so that we can get the drills turning on the ground. We have excellent targets to drill at four locations, with a number of key indicators pointing to existence of extensive LCT systems, and drilling is the next phase of exploration planned here. At Robinson Bore alone, for example, we have identified a lithium trend of 4km that needs to be drilled.”
Lockier Range Lithium Pegmatite Targets
In addition to the Robinson Bore rock chip results announced to the market on 16th October 2023, all rock chip and soil samples across the Yinnetharra Lockier Range Project have been received, with analysis of LCT pegmatite results now completed (Figure 1).
Recent rock chip sampling aimed to identify highly fractionated and fertile pegmatites across the Lockier Range Project through feldspar and mica multi-element analysis, as well as whole-rock pegmatite analysis. Recent soil sampling aimed to identify anomalous trends indicative of potential blind, fertile pegmatites at Robinson Bore, the Eastern Pegmatite Field and Mt Yaragner.

Robinson Bore
The Company has successfully identified a coherent 4km x 2km northwest-trending Li-Cs-Ta-Be-Rb-Bi in-soil anomaly at Robinson Bore, coincident with the recently announced 2.5km-long northwest-trending corridor of fractionated pegmatites (Figure 2). A total of 140 soil samples returned Li2O results above 100ppm at Robinson Bore, mirroring the trend of sub-cropping mapped pegmatites.
The majority of pegmatites at Robinson Bore occur in sub-crop, with vast areas concealed by cover material. The in-soil anomalies have generated additional targets where potential blind pegmatites are present, notably along the fractionation trend (Figure 2).

Eastern Pegmatite Field
The Eastern Pegmatite Field is located directly adjacent to the fertile Thirty Three Supersuite granite that is thought to be the source of lithium-bearing pegmatites at Delta Lithium’s Yinnetharra Project. Soil Sample results at the Eastern pegmatite Field have returned a coherent 2.7km x 2km Li-Cs-Ta-Be anomaly, with 61 soil samples above 100ppm Li2O (Figure 3). No outcropping pegmatites were found, with the in-soil anomaly generating targets for potential blind pegmatites.
A significant northwest trend in Sn-W-Bi pegmatite pathfinders extends from the mapped margin of the fertile Thirty Three Supersuite granite from the Eastern Pegmatite Field soil anomaly through to the sub-cropping Robinson Bore Pegmatite Field (Figure 3).

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.
