The LOI has been entered into pursuant to the agreement entered into between the Company and 1322645 BC Ltd. and announced by the Company in its new release dated March 17, 2026. As such, the transaction contemplated in the LOI is considered a "related party transaction" within the meaning of Multilateral Instrument 61-101 ("MI 61-101"). The Company is relying on exemptions from the formal valuation requirements of MI 61-101 pursuant to section 5.5(a) and from the minority approval requirements of MI 61-101 pursuant to section 5.7(1)(a) in respect of such insider participation, as the fair market value of the transaction, in so far as it involves interested parties, does not exceed 25% of the Company's market capitalization.

About the Uranium Exploration Portfolio

The Property is comprised of three projects (the "Projects", each a "Project"): the Hamilton Basin Project, the Algebuckina Project and the Yalyirimbi Project. The Property represents a rare opportunity to enter the energy sector in a jurisdiction with existing uranium mining, transportation and export regulations and infrastructure¹. The Company believes that the Property is highly prospective for large-scale, sedimentary-hosted uranium mineralisation².

The flagship Project, Hamilton Basin, located in South Australia, is highly prospective for roll-front and palaeo-channel type uranium. Encompassing almost the entirety of the sedimentary Mesozoic-Cenozoic basin after which the Project is named, covering an area of 10,655sqkm of granted Exploration Licences (Table 1), the Hamilton Basin Project is considered to be a large scale, untested uranium exploration target.

The Hamilton Basin Project is located in the northern central part of South Australia, centred on longitude 134° 40' E and latitude 26° 50' S.

Previous exploration in the Project area has confirmed the existence of high levels of uranium in basement rocks and high levels of uranium in the Hamilton Basin sedimentary sequence. Furthermore, limited historical drilling in the 1980's³ has identified palaeo-channel-hosted uranium mineralisation.

Based on proprietary regional geological and geographical studies, and historical exploration results, a very large roll-front uranium system is believed to have persisted at the Hamiton Basin Project.

The Algebuckina Project is the second Project in the Property portfolio and is also located in South Australia. The Project consists of one Exploration Licence covering 273sqkm (Table 1) and is considered prospective for roll-front and unconformity-type uranium mineralisation.

The Algebuckina Project is also located in the northern central part of South Australia, centred on longitude 135° 45' E and latitude 27° 55' S.

Previous exploration at the Algebuckina Project identified uranium enrichment in a basal sedimentary sequence outcropping within the Project, as well as numerous occurrences of uranium mineralisation within basement rocks immediately south of the Project. The proximity of uraniferous "hot rocks" is an important component of the exploration model.

The Algebuckina Project hosts two discrete uranium exploration targets. The first, the Hastings Target, corresponds to a known uranium occurrence within a discrete radiometric anomaly measuring approximately 7km long. Hastings is prospective for unconformity-related uranium mineralisation.

The second target, the Mount Harvey Target, corresponds to a discrete radiometric anomaly associated with the sedimentary Cadna-Owie Formation, which extends for approximately 30kms across the Project. Mount Harvey is prospective for roll-front uranium mineralisation.

The Yalyirimbi Project, the third Project in the Property portfolio, is located in the Northern Territory and includes one granted Exploration Licence covering 247sqkm (Table 1) and two application Exploration Licences covering 324sqkm (Table 1). The Company believes the Project is highly prospective for palaeo-channel and REDOX type uranium mineralisation in the style of the Four Mile and Beverley uranium deposits of the Frome Embayment in South Australia. The Four Mile and Beverly deposits contain approximately 100Mlb of uranium⁶. Yalyirimbi is also considered prospective for ionic-clay REE enrichment.

Yalyirimbi is located in the central part of the Northern Territory, centred on longitude 132° 50' E and latitude 22° 35' S.

Previous exploration at the Yalyirimbi Project, which includes airborne electromagnetic surveying, has identified more than 50km of incised palaeo-channels containing Eocene-aged uranium-bearing sediments. Importantly, this palaeo-channel system lies immediately adjacent to the Yalyirimbi Range that hosts high levels of uranium in basement rocks outside of the Project. The headwaters of the palaeo-channels emanate from the range front draining this large uraniferous source area.

Only two historical drill holes have tested the Yalyirimbi palaeo-channel system with both holes intersecting uranium mineralisation⁷ which supports the robust nature of the exploration model. Such limited drilling - despite its success in intersecting mineralisation - has inadequately tested the large palaeo-channel system, including the upper reaches of the channels that lie proximal to the uranium source rocks.

Access to the publicly available airborne electromagnetic survey data, which is a crucial geophysical technique used to identify palaeo-channel systems, marks the Yalyirimbi Project for near-term, targeted drilling.

The Yalyirimbi Project is also considered prospective for ionic-clay hosted rare earth elements (REE) with the world's largest REE-uranium-phosphate deposit⁸, Nolans Bore, located 30km east of the Yalyirimbi Project and proximal to the Project's palaeo-channel system.

Summary

Golden Age is tremendously excited by the acquisition of this large-scale uranium portfolio and considers the upside potential of these three Projects as unprecedented. All Projects host existing uranium occurrences and large-scale targets that include walk-up drill targets. The flagship Project, Hamilton Basin, has the potential to develop into a significant roll-front uranium precinct. Golden Age is in an enviable position to have secured exploration rights to almost the entire Hamilton Basin, which has only seen minimal exploration historically.

The Projects comprising the Property were generated by Ross Brown, a sedimentologist and geomorphologist with over forty years' mineral exploration experience. In the 1990's Mr Brown was involved in resource drilling at the Mulga Rock uranium deposit in Western Australia and, in 2006, founded Oklo Uranium to explore for Langer-Heinrich style palaeo-channel uranium in Australia and Africa. Oklo listed on the Australian Security Exchange (ASX) in 2007, raising $8M. In recent years, Mr Brown has applied his modified uranium Exploration Model to sedimentary terrains in central Australia, generating high-quality projects. In 2024, Mr Brown collaborated with Rob Heaslop to secure the Mac Minerals uranium portfolio that Golden Age now has an option to acquire.
