Drill Results

Leviathan Gold, via Core Prospecting Pty Ltd. Receives Results, from Phase 2 Diamond

Drilling at the Excelsior Prospect.

• A total of 640.85 meters of diamond drilling over 5 holes has been completed by Core

Prospecting Pty Ltd.

• Highlights include 0.41 meters at 6.3 g/t Au in hole EH0 30 terminated in a void

thought to represent historic underground mine workings, and 1.62 meters at 5.3 g/t

Au and 0.27 meters at 14.5 g/t Au in hole EH031,

• Drilling is ongoing and form s part of an ongoing 4,000 meter diamond drilling

program being undertaken by Core , the expected cost of which is approximately

CAD$950,000.

Vancouver, BC – September 10, 2024 - Leviathan Gold Ltd. (“ Leviathan”, the “Company”)

(LVX – TSXV, 0GP – Germany) is pleased to announce receipt of initial assay results from Phase

2 diamond drilling currently under way at its Excelsior Prospect (“Excelsior”) pursuant to a Heads

of Agreement entered into between Leviathan and Core Prospecting Pty Ltd (“Core”) on July 17,

2023 as subsequently amended on January 16, 2023 (“ HOA”). Excelsior lies within the

Company’s Avoca Project in the Victorian Goldfields, Australia.

A total of 640.85 meters of diamond drilling over five Phase 2 holes has now been completed by

Core in a south-easterly oriented fan of drill holes designed to test for north-easterly continuation

of high-grade hanging wall mineralization identified during the first phase of drilling, as reported

by the Company on June 25, 2024 (Figure 1). This work forms part of a n ongoing 4,000 meter

diamond drilling program being performed by Core, the expected cost of which is approximately

CAD$950,000.

Results from the first two holes of this program (EH030 and EH031) have been received , and

include 0.41 meters at 6.3 g/t Au and 1.62 meters at 5.3 g/t Au in hole EH030, which terminated

in previously mapped underground mine workings . While drilling had been designed to target

mineralized structures beyond these workings, deviation of the drill string is understood to have

brought about this intersection, and nevertheless validates Core’s targeting model. An interval of

0.27 meters at 14.5 g/t Au was returned in hole EH031. Additional drilling will be required to

determine the true thickness of mineralization.

The purpose of the current Core program is to drill beneath and along- structure from intervals

previously reported by Leviathan from Excelsior, which include 8.24 g/t Au over 6.63 meters

(54.63 gram meters), from 161.95 meters in hole EH003 (press release of April 21, 2021); 5.40 g/t

Au over 11.02 meters (59.51 gram met ers), from 84.37 meters in hole EH005 (press release of

April 26, 2021) and 4.85 meters at 9.0 g/t Au (43.66 gram meters) in hole EH014, 3.13 meters at

56.9 g/t Au (178.23 gram meters), in hole EH017 and 12.68 meters at 9.2 g/t Au, (116.85 gram

meters), in hole EH029 (press release of June 25, 2024). These intervals are believed to represent

the down- dip continuation of mineralization observed in historic mine workings, and are

characterized by intense quartz veining, visible gold, and enveloping sericitic alter ation and base

metal sulphides.

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..

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 mete rs 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 2 5,

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 Resource s as estimated in the JORC Report, payable upon

- 2 -

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. Sampl es 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

- 2 -

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.
