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).

Odessa Minerals
Overview
Odessa Minerals (ASX:ODE) is an ASX-listed junior mining and exploration company focusing on uranium exploration in the Gascoyne Region of Western Australia via its three projects— Lyndon Project, Relief Well and Gascoyne East.
Odessa Mineral’s pivot towards uranium and away from lithium is a smart move, especially in the current environment of high uranium prices. Uranium prices have soared to their highest point since 2008, surpassing US$100 per pound. This upward trend is expected to continue due to the ongoing supply and demand imbalance for uranium. With its portfolio of uranium projects, Odessa is strategically positioned to capitalize on these robust market fundamentals.
Odessa Minerals’ projects in the Gascoyne Region of Western Australia totalling >3,000km2
The company’s flagship Lyndon project is immediately adjacent to Paladin Energy’s 15.6 million pounds (Mlbs) U3O8 Carley Bore uranium project. The Lyndon Project has identified highly significant uranium intersections with some rock chip sample assay results showing exceptional grades up to 6,612 parts per millions (ppm) U3O8 at the Baltic Bore and Jailor Bore prospects. Odessa plans to begin drilling at the target areas in 2024.
The other two projects—Relief Well and Gascoyne East—have shown significant potential for uranium. An extensive palaeochannel stretching over 8 kilometers has been verified at Relief Well, offering the potential for uranium mineralization in a roll-front style. Odessa is planning a drilling program to test roll-front uranium mineralization at Relief Well.
The Gascoyne East project is one of the most under-explored areas in the Gascoyne Province. The company has identified multiple gold, copper and uranium targets for the project, and drilling has been planned for 2024.
The company is in the early stages of its operations, making it attractive for investors looking to get exposure to uranium assets in a tier-1 mining region like Gascoyne. The high insider holding, at nearly 28 percent, is an encouraging sign for investors as it aligns management’s interests with those of the shareholders.
Company Highlights
- Odessa Minerals is an ASX-listed, uranium exploration company with a large holding covering over 3,000 sq. km. in the Gascoyne region of Western Australia. The company has three key projects in the area – Lyndon, Relief Well, Gascoyne East.
- The company focuses on advancing uranium prospects at its flagship project, Lyndon. Lyndon is adjacent to Paladin Energy’s Carley Bore uranium project, which has a resource base of 15.6 Mlbs U3O8.
- Initial review of the Lyndon project has identified highly significant uranium intersections at the Jailor Bore, Baltic Bore and Ben Hur prospects, with some exceptional grades reaching up to 6,600 ppm U3O8.
- The Relief Well Uranium Project has revealed significant palaeochannel-hosted uranium mineralization typically amenable to low-cost recovery. The company will move forward with drill planning and seek approvals to conduct drilling at the Relief Well prospect.
- Uranium prices have surged to their highest level since 2008, exceeding US$100 per pound. This upward trend is anticipated to persist due to the tight supply and demand balance for uranium. Odessa's portfolio of uranium projects is well-positioned to benefit from strong fundamentals.
- The Gascoyne East project has extensive gold, copper and uranium targets that were identified during the recent airborne survey. The company is planning air-core and RC drilling for the project in 2024.
- The Company’s senior leadership team is well-experienced in the mining sector and has significant ownership in the company at nearly 28 percent. This is an encouraging sign for investors as it aligns the management’s interest with that of the shareholders.
Key Projects
Lyndon Project
The Lyndon project tenements total 1,000km2 of highly prospective ground for REE/lithium exploration. The project has also shown signs of significant uranium potential, making the company pivot towards it and aligning its priorities to uranium exploration. The initial fieldwork on the project has yielded impressive results.
Jailor Bore, Baltic Bore and Ben Hur prospects showed significant calcrete-hosted uranium mineralization at the surface. The findings at the Balti Bore and Jailor Bore included 12 rock chips with assays revealing over 1,000 ppm U3O8 and five rock chips with assays showing more than 1,000 ppm V2O5 (vanadium oxide).

Baltic Bore prospect: The Baltic Bore prospect area features several radiometric anomalies linked to calcrete terraces, extending over a strike length of 2.6 km. Baltic yielded a noteworthy 6,612 ppm U3O8 while also uncovering 2,132 ppm V2O5 in sample XT0970. An additional eight samples show rock chip assays exceeding 1,000 ppm U3O8. Historically, little attention has been paid to the Baltic Bore prospects compared to Jailor Bore. However, the assay results at Baltic Bore indicate significant potential for high-grade uranium discovery.
Jailor Bore target: Jailor Bore encompasses more than 2 km of uranium radiometric anomalies along its strike length. Surface mineralization has been observed at this target, with four rock chip assays exceeding 1,000 ppm U3O8, with a maximum of 4,489 ppm U3O8. Additionally, high vanadium levels were found to be associated with uranium mineralization, with rock chip XT0929 showing up to 1,541 ppm V2O5.
Ben Hur, Giant and Red Hill Uranium Targets: The Ben Hur, Giant and Red Hill prospects exhibit calcrete-type uranium mineralization similar to that found at the Baltic Bore and Jailor Bore. Historical exploration reported intersections up to 2 meters @ 411 ppm U3O8 from 4 meters.
Relief Well Project
VTEM survey data has confirmed the presence of a palaeochannel at the Relief Well prospect with a strike length of greater than 8 km that remains open to the south. The palaeochannel-hosted uranium mineralization at the Relief Well prospect is typically amenable to low-cost in-situ leach recovery. Relief Well is situated directly along the strike and serves as an upstream extension of the paleochannel that hosts Paladin Energy’s Carley Bore, which contains a 15.6 Mlbs U3O8 resource. The company will now move forward with drill planning and will seek approvals to conduct drilling at the Relief Well prospect.
Gascoyne East Project
The Gascoyne East Project tenements cover 2,108 sq. km. of exploration licenses. The Gascoyne East project is one of the most under-explored areas of the Gascoyne Province. The company has identified multiple gold, copper and uranium targets for the project, and is planning a two-phase air-core drilling program. Phase 1 air core drilling with hole spacings ranging from 200 meters to 400 meters aims to update the basement geology model and rank targets for the follow-up Phase 2 drill program, which will test for mineralization at depth. Phase 1 drilling is expected to commence in Q3 2024.

Unconformity Uranium Drill Targets Identified from 2024 Geophysical Data
Key Highlights
- Final data received and interpretation completed for the ground electromagnetic geophysical surveys from the winter 2024 program at the Marshall and North Millennium projects.
- Several conductive anomalies identified at Marshall, located above and below the unconformity, consistent with regional exploration model.
- Stacked anomalies concurrently with multigenerational geophysical data provides a base to assess the exploration targets and refine drillhole targets.
- The projects are located 15 kilometres from the majority Cameco owned Millennium deposit, and just 40km from the world class McArthur River mine.
- Basin remains funded for the next round of field exploration.
The ground electromagnetic successfully identified 3 main targets which confirms the geological and exploration model. Of note is Target 1 (Figure 1), where modelled EM plates below the unconformity align with a sandstone ZTEM anomaly, which is interpreted to be alteration within sandstone. The identification of these targets is encouraging and consistent with regional trends in the southeastern Athabasca and provides increased confidence in drill hole targeting. Basin is currently reviewing options and priorities of how to progress exploration of these confirmed targets.
Basin’s Managing Director, Pete Moorhouse, commented:
“Conducting ground geophysical surveys on Marshall and North Millennium was a milestone in advancing these underexplored projects in Basin’s uranium portfolio. The form of these anomalies is highly encouraging given the proximity to some of the world’s largest uranium deposits.”
Key results
Following the encouraging conductive anomalism highlighted by the 2023 3D inversion of two historic airborne Electromagnetics (Z‐Tipper Axis) (“ZTEM”) datasets partially covering the current North Millennium and Marshall projects3,4, Basin contracted Discovery International Geophysics5 to carry out ground Stepwise Moving Loop Transient Electromagnetic (‘Ground EM’) surveys on areas of immediate interest within the Projects.
Figure 1 Three main anomalies shown from 2024 ground EM, in plan view (top diagrams) and cross- section looking northeast (bottom diagram). The ground EM anomalies are displayed with the modelled plates against the historical ZTEM data.
The 2024 Ground EM survey data returned six conductive anomaly picks producing three main target areas (Figure 1). The anomalies correlate strongly with the southern edge of the circular ZTEM conductive anomaly at Marshall and the interpreted northern edge of the circular anomaly identified in the historic data. A weaker EM pick was also interpreted centred between the two prominent ZTEM conductivity anomalies.
Three-dimensional modelling using Maxwell produced six electromagnetic conductive plates within the basement stratigraphy, all below the unconformity (Figure 1). The two southeastern plates are clearly aligning with a conductive sandstone ZTEM anomaly identified from the historic data, which is above the interpreted unconformity. This is interpreted as potential basal sandstone alteration proximal to the EM anomalies and constitutes a high-priority drill target area, refer figure 2.

Airborne EM over Multiple Targets on Ti-Tree Project
- Augustus Minerals has contracted UTS Geophysics to conduct a VTEM Max survey over several Copper, Cu-Ni-PGE, Zn-Pb-Ag and Uranium targets along the money Intrusion and within proximity of the prospective 85k long Ti-Tree Shear.
- The surveys will cover:
- The Money Intrusion, prospective for Cu-Ni-PGE mineralisation.
- Copper Ridge and Nics Bore over anomalous Copper Drilling results
- The Coo Creek prospect where drilling by Augustus in 2023 identified strongly anomalous Zn-Pb-Ag mineralisation.
- The Munaballya Well North area which shows potential for economic Uranium mineralisation.
- The surveys will help to advance the untapped potential of the Ti-Tree project to host economic mineralisation of multiple commodities.
Andrew Ford, GM Exploration
“The VTEM survey will provide key targeting data over three highly prospective and different prospects with potential for multiple commodities. Whilst the high prospectivity for copper mineralisation has been well documented, the addition of uranium and Broken Hill base metal style mineralisation highlights the quality of the underexplored Ti-Tree project”.
VTEM
UTS Geophysics has been engaged to conduct a helicopter borne VTEM Max survey comprising 646-line km over three separate survey areas. The system is excellent for locating discrete conductive anomalies as well as mapping lateral and vertical variations in resistivity which helps map structure, alteration and rock type. The system also collects magnetic data through a caesium magnetometer. The transmitter/receiver loop is suspended on a cable approximately 40m below the helicopter (Figure 1).
Figure 1 VTEM Max helicopter deployed electromagnetic survey arrangement.
Figure 2 Prospects and VTEM Survey areas.
Money Intrusion
The Money Intrusion, which has proven potential to host Ni-Cu-Co-PGE (platinum group elements), is part of the regional Mundine Well Dolerite Suite, a regionally extensive dolerite (strike length >80km). This extensive mafic intrusion, which is comprised of a variety of lithologies, including gabbro in the core, olivine dolerite on the chilled lower contact or keel and fine-grained dolerite on the outer edges. Mapping, aeromagnetics and multi-spectral imagery show that the Money Intrusion within the Ti-Tree Project covers a strike length greater than 16km, reaching widths >600m in the north of E09/23241.
