• Resource Base is aligned with environmental consulting group Rivertech and geological resource consultants IHC mining to maximise the progression of the project in line with environmental best practice and state legislative requirements
• Drilling is expected to commence later in 2023 however, is dependent on th e Victorian state government approval process

CORPORATE

• Cash at 30 September of ~$1.147 million

James Bay Lithium Projects

On 1 May 2023, the Company announced that it has completed the acquisition of the Wali and Ernst Lake Lithium Projects, located in the prolific James Bay Lithium District in northern west-central Québec, Canada (Acquisition) (James Bay Projects). Details of the Acquisition are set out in the announcement dated 24 February 2023.

Wali Lithium Project Overview

The Wali Lithium Project comprises 100 mineral claims totalling 5,112 hectares (51.12 Km2 ) located in the James Bay Region of northern west-central Québec. The Wali Project is located in the LaGrande sub-province of the Superior Province, ~16km east of Patriot Battery Metals (ASX:PMT) Corvette prospect. The Property sits along the volcanic belt and encompasses various intrusive suites including the lithium pegmatite prospective source rocks of the Vieux Comptoir Granitic Suite which have been mapped on the property.

Regionally, the Vieux Comptoir Granitic Suite is known to host K-feldspar granite phases in pegmatite form which may host an abundance of spodumene. Wali is underlain by the source rock (Vieux Comptoir suite) which would have injected pegmatite dykes into those greenstone rocks in the region.

Geologically, the greenstone within the Wali Project is interpreted to be a 'dismembered' section of the same greenstone belt that hosts Patriot's CV5 discovery.

Ernst Lake Lithium Project Overview

The Ernst Lake Lithium Project comprises 109 mineral claims totaling 5,631.72 hectares (56.31 Km2 ), located in the James Bay Region of northern west-central Québec.

The Ernst Lake Project is located directly along the Trieste formation like recent lithium discoveries made by Winsome Resources Limited (ASX: WR1) on its Adina project. The Project is located just 13km south of the Adina Project partly within the same greenstone belt which is prospective for lithium with over 10km of strike.

Summer Field Work Program

During the quarter, the Company provided an update on the on ground field activities at the James Bay Lithium projects. Resource Base has identified an abundant number of outcropping pegmatites and boulders over both projects with as at 30th September a total of 14 days in the field. One of the significant finds within the first pass on-ground exploration is a topographic high along strike from the Corvette discovery (ASX:PMT) with encouraging potassium to rubidium ratios returned from a handheld XRF, indicating lithium bearing pegmatites may be present.

The in-country team has also discovered various cross-cutting structures over the glacial dispersion of the known North-East to South-West geological trend with numerous clusters of pegmatites.

Wali Project

The Wali project has uncovered various prospective zones of up to 1.6km strike length of pegmatitic outcrops, with 40 rock chips from pegmatites sent to the lab to be assayed from the first eight (8) days on the project.

The total strike length of the dykes paired with the magnetic data (See ASX announcement "High-Priority Targets Identified at Wali Lithium Project") suggests structural complexity over various strike directions, abutting the greenstone and granite contact (see Figure 3).

Ernst Lake Project

The Ernst Lake project has exposed numerous pegmatites and outcrop-boulders in the first six (6) days on the project. A distinctive trend has been mapped hosting 44 pegmatitic outcrops within the metasediment and greenstone host of the Trieste Belt. The South-West to North-East system within the incumbent glacial trend has recorded fertile pegmatites of interest with the discoveries extending from the north to the southern strike of the Ernst Lake claim.

Mitre Hill REE Project

The Company believes the Murray Basin has the potential to be a globally significant REE precinct.

The Mitre Hill Project tenements are highly prospective for clay hosted Rare Earth Elements (REE) within the southern margin of the Murray Basin on the South Australia / Victoria border. Drilling results have confirmed the occurrence of shallow mineralisation across the two tenements drilled so far.

The maiden JORC Inferred Mineral Resource estimate of 21 Mt @ 767 ppm TREO consists of thick zones of near-surface mineralisation. Significantly, the existing resource has the potential to substantially grow in size and scale as the Mineral Resource estimate only incorporates a portion of the identified Exploration Target drilled to date. The Company has also completed significant aircore drilling in Exploration Lease EL7646 located approximately six (6) km east of EL7647 however is not included in this Mineral Resource estimate.

Resource Base has estimated an Exploration Target at EL007647 of 13 Mt – 34 Mt at 630-830 ppm TREO (refer ASX announcement 3 February 2023 and 5 October 2023).

Metallurgical Testwork

During the quarter the Company announced the results of its preliminary metallurgical testwork for the Mitre Hill REE Project which confirmed the ionic nature of the deposit and therefore potential for conventional separation.

Two (2) assayed holes were randomly selected from within the mineralised envelope and test-work supervised and conducted by Strategic Metallurgy laboratories in Perth, Western Australia. The aim of this initial phase of testwork was to broadly understand the metallurgical and processing requirements to recover rare earths from the Mitre Hill project. Simple bottle-roll leaching tests were undertaken under standard desorption conditions of 1.25 M (166gpl lixiviant concentration) using ammonium sulfate as the lixiviant, at pH 3.0, adjusted by addition of sulfuric acid, and left overnight for circa 16 hours.

Clay-hosted REE deposits have advantages over hard rock deposits as they typically contain a higher proportion of magnet earth elements, within generally, shallow hosted deposits. Processing of ionic deposits is a more simplistic process, as the acid separates the minerals with the rare earths remaining within the adsorbed segment, creating superior mining economics.

Drill Program Planning

The Company is currently in the process of engagement with landowners and DEECA (Department of Energy, Environment and Climate Action) to obtain approvals for the next phase of drilling at Mitre Hill, which seeks to expand and upgrade the current JORC inferred mineral resource estimate of 21 Mt @ 767 ppm TREO.

Resource Base is aligned with environmental consulting group Rivertech and geological resource consultants IHC mining to maximise the progression of the project in line with environmental best practice and state legislative requirements.

Drilling is expected to commence later in 2023 however, is dependent on the Victorian state government approval process.

Black Range Project

During the quarter, the Company advised that while the Company had consulted extensively with the Victorian Regulators and its tenement manager, the Company has been unable to satisfy the necessary geological evidence required to allow the granting of a RL over the Black Range tenement in an outcome which was flagged as a key risk in the prospectus at the time of re-admission. While there are avenues to explore opportunities to reapply for the tenements, this lengthy process is not in-line with the Company's current corporate focus.

Competent Person Statement

The Information in this report that relates to exploration results, mineral resources or ore reserves is based on information compiled by Mr Michael Beven, a consultant to the Company, who is a Member of the Australasian Institute of Geoscientists. Mr Beven has sufficient experience which is relevant to the style of mineralisation and type of deposits under consideration and to the activity that he is undertaking to qualify as a Competent Person as defined in the 2012 edition of the `Australian Code for Reporting Exploration Results, Mineral Resources and Ore Reserves' (the JORC Code). Mr Beven consents to the inclusion of this information in the form and context in which it appears in this report. Mr Beven does not hold securities in the Company.

The Company first released the exploration results relating to Mitre Hill Project tenement EL007646 on 18 May 2022 and further results were released on 23 August 2022. The Company first released the exploration results relating to Mitre Hill Project tenement EL007647 on 10 October 2022, and further results were release on 24 October 2022. The Company first released the JORC mineral resource estimate on 3 February 2023. The Company confirms that it is not aware of any new information or data that materially affects the information in the relevant market announcement.

Cautionary Statement: In relation to the disclosure of visual mineralisation, the Company cautions that visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analysis. At this stage it is too early for the Company to make a determinative view on the abundances of any of these minerals. These abundances will be determined more accurately through petrography, assay, and XRF analysis. The observed presence of pegmatite does not necessarily equate to lithium mineralisation. It is not possible to estimate the concentration of mineralisation by visual estimation and this will be determined by chemical analysis.

The Company notes that pegmatites contain varying abundances of typical LCT pegmatite non-Li-bearing minerals, predominantly feldspar, quartz, muscovite mica (as a group also referred to as Alpite) and accessory tourmaline. Investors should note that while LCT pegmatites are a known host for accessory lithium bearing minerals such as spodumene, it is also known that this is not a universal association.
