Interpretative work on drilling completed to date continues to suggest the presence of a northeast plunging mineralized dilational zone consisting of quartz reef and associated splays in which gold is hosted in quartz veins.

Highlights of results published in this release are provided in Table 1, collar information in Table 2, and full results in Table 3.

Leviathan Gold Chief Executive Officer, Luke Norman, remarked: “Following on from the success of Core Prospecting’s Phase 1 program at Excelsior, ongoing drilling and geological work appears to demonstrate the potential for north-eastward strike extensions to Phase 1 gold mineralization at the property. With over 3,000 meters of diamond drilling remaining to be completed by Core under their current Phase 2 program, these works continue to provide Leviathan with the opportunity to define a high-grade gold deposit of significance. We once again thank Core for their considerable efforts to date and look forward to working with their highly skilled team as this program continues to evolve.

About the HOA

Under the terms of the HOA, Core may earn an initial 40% interest in a three square kilometre area within EL5387 (the Excelsior Area of Interest, or “AOI”) by completing, at Core’s sole cost and expense, 2,000 meters of diamond drilling including assays by April 17, 2024 (“Phase 1”), and a further 35% interest in the AOI for an additional 4,000 meters of diamond drilling including assays and preparing an independent JORC report (the “JORC Report”) identifying an Indicated and/or Measured Mineral Resource within 12 months from the end of Phase 1, each at Core’s sole cost and expense (“Phase 2”). In lieu of completing such further drilling, Core may instead prepare, at its sole cost and expense, a JORC report containing Indicated and/or Measured Mineral Resources of not less than 50,000 ounces of gold at a cut-off grade of 2.5g/t Au within the AOI. Upon fulfilment of certain conditions by Core, Leviathan shall on behalf of Core apply for a standalone tenure over the AOI, (the “New Tenement”). If Core fails to complete Phase 2 they shall forfeit any interest under Phase 1 and shall have no interest in the AOI.

As a result of Core completing the initial phase of diamond drilling (press release of June 25, 2024), and commencing its second phase of diamond drilling, it has earned a 40% interest in in a New Tenement to be applied for by Leviathan, subject to the fulfilment of certain further conditions by Core.

Upon Core having attained a 75% equity interest in the AOI, Leviathan may either contribute its share of costs and maintain its equity interest or be diluted pro-rata to a minimum carried interest of 5%, which Core shall purchase from Leviathan for the sum of AUD$150 per ounce of Indicated and/or Measured Mineral Resources as estimated in the JORC Report, payable upon commencement of gold production. Alternatively, Core may, within 12 months of the completion of Phase 2, purchase Leviathan’s holding in the AOI for the sum of AUD$75 per ounce of Indicated and/or Measured Mineral Resources in the JORC Report, or Core may within 12 months of the completion of Phase 2 purchase Leviathan’s holding in the Excelsior AOI by paying instalments of AUD$25,000 per quarter, increasing to AUD$75,000 per quarter, commencing from the date on which a New Tenement is granted and continuing for the life of any gold production mine located within the area of the AOI.

The HOA also provides that Leviathan may, subject to Core first completing Phase 1, claw back Core’s equity stake in the AOI for the sum of AUD$500 per meter drilled, or after receipt of the JORC Report for AUD$150 per ounce of gold mineralisation estimated and classified as an Indicated Mineral Resource and/or a Measured Mineral Resource in the JORC Report.

About the Excelsior Prospect

The Excelsior prospect is interpreted to host structurally controlled gold mineralization developed within quartz veins. Historic production records from Excelsior indicate the mining of 13,200 tons for 9,260 ounces of gold down an ore shoot to a depth of 100 meters at an average recovered grade of 22 g/t Au between 1909 and 1915¹, with said mineralization open to depth and along strike. A total of 1,917 meters in 11 holes have been drilled at Excelsior by Leviathan to date.

Qualified Person and Data Verification

The technical content of this news release has been reviewed, verified and approved by Keith Whitehouse, MAusIMM (CP Geol), MAICD, Exploration Manager of Leviathan Gold (Australia) Pty. Ltd., a qualified person as defined by NI 43-101.

Drilling was carried out by Core using their equipment, and all core was drilled at NQ size. Average core recovery for the program was 96.6%. Drill core was cut in half by Core using a diamond saw, with one half of the core then taken as a sample for analysis. Samples were sawn along the bottom of hole orientation line, or if none present a consistent cutline as marked by the logging geologist. Sample intervals were generally between 10 and 150 centimetres, producing samples of between 0.27 to 4.0 kg. Samples were delivered to On Site Laboratory Services (Pty) Ltd (“On Site”), in Bendigo, Victoria. The samples were coarse crushed to P80 <2mm using industry standard Boyd crushers with a 1kg sub-sample being packed into standard containers for assay using a Chrysos Corporation Photon Assay analyser, lab method code PAAU02. Regular crush duplicates were generated and reported by the laboratory together with regular replicate results of the primary sample. Replicate results were provided for 100% of gold grades greater than 10 g/t and more than 85% of grades greater than 5 g/t. Core routinely inserted Photon Assay certified geochemical standards and blanks together with samples flagged for coarse crush duplicate-sampling into the drill core sample stream as part of a documented Quality Assurance/Quality Control (“QAQC”) process to monitor laboratory performance. During the drilling program QAQC material was inserted into every sample batch at the following average rates per primary sample: crush duplicates 1 in 30; basalt blanks 1 in 30; certified reference material 1 in 30. QAQC sampling was considered to provide acceptable results. Sample grades were checked against recovery percentage for potential bias; no discernible high- or low-grade bias was observed.
