Site Visit Completed to Crofton Gold Project, W.A.

Cloudbreak Discovery Plc (LSE: CDL), a London Stock Exchange Main Market listed company, is pleased to announce that the maiden site visit has been completed to the Crofton Gold Project ("Crofton") which is located 120 kilometres east-southeast of the 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 3). 

The purpose of the 3-day helicopter-supported Crofton site visit was to review areas where previous gold results up to 253g/t gold and 215g/t silver with visible gold had been recovered (as announced on 9 October 2025), and to assess vehicle access and logistics for future exploration programs.

Tom Evans, Cloudbreak's MD, commented; "I am delighted to report a successful maiden site trip to Crofton, where company geologists took 54 samples from previous and new target areas. Observations of substantial quartz veins over hundreds of metres and tens of metres wide adds to the prospectivity of the project where bonanza grade gold samples up to 253 g/t were taken and historic gold production averaged 150g/t. A systematic exploration program consisting of in-fill and extension soil sampling, rock chip sampling and geological mapping is being designed and expected to commence in early 2026, after the wet season. This incredibly exciting gold project in Western Australia adds significantly to our growing portfolio of gold assets in a period of record gold prices and resurgent silver prices."

Findings from Maiden Site Visit

Crofton hosts an approximately 20km2 area of laterally extensive quartz veining hosted within the Yilgalong granite. Quartz veins are commonly 10s of metres wide and can be seen to extend along strike for 100s to 1,000s of metres. A total of 54 samples were taken around locations of previously reported gold results and along strike.

On the ground, quartz veins were observed to host zones of boxwork iron oxides, primary sulphides including pyrite and galena, and copper-oxide stainings (Figure 2), which are all indicators for the presence of hydrothermal fluids, that may contain gold and silver mineralisation. Previously reported rock chip results from some of these zones included.

· 48.63 g/t Au (RBR015)

· 62.48 g/t Au (RBR017)

· 20.61 g/t Au (RBR020)

· 12.24 g/t Au (RBR021)

· 253.59 g/t Au (RBR022)

· 195.53 g/t Au (RBR028)

· 10.22 g/t Au (RBR030)

· 2.78 g/t Au (RBR032)

Numerous additional zones of outcrop that looks similar to the above previously sampled locations, were observed during the maiden site visit.

Given the extent of quartz veining and the relative lack of systematic work completed to date at Crofton, a systematic exploration program consisting of in-fill and extension soil sampling, rock chip sampling and geological mapping is highly warranted. Planning for these programs is underway and expected to commence in early 2026, after the wet season. This work will assist with defining zones within the extensive quartz vein network, for the company's maiden drilling program.

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 3). 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:

Samples have been submitted to ALS Perth, with results expected in 4-6 weeks. Planning for regional soil sampling - including orientation surveys - is underway and works are planned to start after the Australian summer concludes in March/April 2026. This will be followed up with geological mapping and rock chip sampling of target areas which will then be reviewed and prioritised for drill-testing.
