Cloudbreak Discovery Plc

('Cloudbreak', or 'the Company')

Acquisition of Crofton Gold Project

Western Australia

Gold grades up to 253 g/t + Silver grades up to 215 g/t

Cloudbreak Discovery Plc (LSE: CDL), a London Stock Exchange Main Market listed company, is pleased to announce that it has secured the exclusive option to acquire the Crofton Gold Project (" Crofton "), located 120 kilometres east-southeast of famous Australian gold mining centre of Marble Bar and 75km northeast of the mining centre town of Nullagine in the Pilbara region of Western Australia ( Figure 2) . The consideration is GBP10,000 for a two (2) month option period with 56,000,000 new ordinary shares to be issued no later than 31 January 2026 in the event that the option is exercised.

Previous soil and rock chip sampling campaigns in 2021 ( Figure 1 ) at Crofton have defined new prospects and returned bonanza-grade gold results, up to 253g/t gold and 215g/t silver (Table 1), with visible gold being common in dumps adjacent to historic test pits.

Historic gold production from the area from 1901-1910 averaged 150 g/t gold.

Soil sampling results range up to 3g/t gold ( Figure 1 ) with multiple trends identified over strike lengths exceeding one kilometre.

Rock chip sampling:

· Observed visible gold in historic test pits

· Waste dump and rock samples returned results including:

o 253g/t, 195g/t, 62g/t and 48g/t gold.

o 215g/t, 150g/t, 48g/t and 17g/t silver.

Soil sampling:

· Anomalies delineated over multiple gold trends over substantial strike lengths exceeding one kilometre.

· Peak gold result of 3g/t (3,000ppb) gold with numerous samples returning values in excess of 10ppb gold

Tom Evans, Cloudbreak's MD, commented: "This is an incredibly exciting gold project in Western Australia and it adds significantly to our growing portfolio of gold assets in a period of record gold prices and resurgent silver prices. The Crofton project has recorded some extraordinary gold grades from recent sampling undertaken in 2021 and historic mining. The delineation of multiple trends with strike lengths of over a kilometre on the tenement give the Company a vast number of high priority exploration targets. We are making plans to have geologists on-site as soon as practicable and I look forward to updating shareholders in short order.

Further, I am also looking forward to reporting on the assay results from our Darlot West project in the coming weeks.

Lastly, I am delighted to report that with this latest transaction and those previously announced since June of this year, we are going to have an extremely busy end to 2025. The refined strategy announced by our Chairman in May of this year, has allowed us to scale appropriately, on material value add to the company's assets, and move swiftly for astute commercial opportunities in a risk abated manner. Importantly the Company remains fully funded for planned works across all portfolio assets. "

About the Crofton Gold Project

Crofton hosts a large area of hydrothermal alteration within the Yilgalong Granitoid, associated with a suite of prominent quartz veins. Historical exploration has been limited to surface sampling programs of stream sediment, soil and rock chip sampling.

The Company will hold a 100% interest in the Crofton property, which consists of one exploration licence application E45/6690 covering 57km² (Figure 2). The Crofton licence covers much of the Boodalyerrie Mining Centre, which has recorded production from 1901 to 1910 of 588.4 ounces gold from 122 tonnes of ore at a reconciled average grade of 150g/t gold.

Future Plans and Assay results update:

The Company plans to undertake a site visit, conduct detailed geological mapping over the geochemical anomalies identified from previous work, and move towards defining drill targets.
