Silver and Gold Grades for Crofton Gold Project
Cloudbreak Discovery Plc has announced significant assay results from its Crofton Gold Project in Western Australia, with new findings revealing gold grades up to 142 g/t and silver grades up to 175 g/t. These results, obtained from multi-element and fire assays, confirm high-tenor gold mineralization across a 1km x 4km area and establish a correlation between gold and silver values, with some samples showing high silver where gold is absent. The company is optimistic about the project's potential, especially given current high precious metal prices, and plans further exploration to refine the relationship between gold and silver.

Cloudbreak Discovery Plc (LSE: CDL), a London Stock Exchange Main Market listed company, is very pleased to announce that further gold assay results up to 142 g/t Au (or 4.5 ounces per tonne gold) and along with silver results up to 175g/t Ag (or 5.6 ounce per tonne silver) have now been recieved from multi-element assay and fire assay, from the site visit to the Crofton Gold Project ("Crofton"). Crofton 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 1).

Tom Evans, Cloudbreak's MD, commented; "These surface results are outstanding and to see the high tenor of gold grades and now these very exciting silver grades, we are very optimistic of the potential for discovery here at Crofton. Silver and gold prices are now at historic highs, which makes Crofton an very exciting project for the Company."
These assay results confirm the high tenor of the gold mineralisation at Crofton and is now establishing a mathematical relationship between Photon and Fire assay for gold - both of which can be used for JORC reporting purposes - and the multi-element results now confirms the presence of very significant silver grades. From the results received to date, we can now see that silver values are high where we have high gold values, but we can also see silver values where there is no gold. Further exploration on site this quarter will refine the relationship between gold and silver.
Sampling Results
Crofton hosts an approximately 20km2 area of laterally extensive quartz veining hosted within the Yilgalong granite. Quartz veins are commonly 10's of metres wide and can be seen to extend along strike for 100's to 1,000's of metres. A total of 54 samples were taken around locations of previously reported gold results and along strike.
Initial work was focused on sampling areas of historically reported gold mineralisation where grades of up to 253 g/t Au have been historically reported. Gold grades > 1 g/t and up to 162.35 g/t have now been confirmed over a 1km x 4km area. The multi-element results and Fire assay being reported in this release confirm the tenor of gold mineralisation and aslo show the high levels of silver up to 175 g/t Ag. This, paired with historical >25 ppb Au soil anomalism, indicates that the Crofton project warrants immediate follow-up in the form of systematic surface geochemical sampling programs and has the potential to host economic quantities of vein-hosted gold and silver mineralisation.
About the Crofton Gold Project
The Company will hold a 100% interest in the Crofton property, which consists of one exploration licence application E45/6690 covering 57km². 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.
