Phoenix District

The Glacier and Cleaver IOCG systems lie 1.9km apart along a major E/W fault zone within the greater Phoenix district and have returned outstanding assay results from the maiden field program. A total of 46 samples were taken along a 1.1km trend at the Glacier system returning copper values between 0.11% and 42.60% from intensely potassic altered andesites. Mineralisation is hosted in veins, disseminated and as the cement phase of hydrothermal breccias. The system sits within the low to high temperature potassic alteration zone, characterized by k-feldspar-hematite-magnetite alteration.

The Cleaver IOCG system has been sampled within a kilometer scale gossan, formed by the oxidation of pyrite within strong phyllic alteration, this positions the Cleaver IOCG above the potassic zones which are observed on surface at Glacier IOCG. The phyllic alteration is host to veins, disseminations and sulphide cemented breccias with abundant pyrite and chalcopyrite. A total of 30 samples were taken at the Cleaver IOCG target and represent a significant discovery by White Cliff Minerals in the maiden field season.

A total of 9 samples were taken from Glacier Gold and 12 samples from Rust respectively.

Epithermal Systems

The Glacier Gold Epithermal Trend located SE of the Glacier IOCG trend is a > 200 m N/S striking zone of quartz-sulphide veining which has returned up to 38.2g/t Au, 76.5g/t Ag and 4.16% Cu (sample F005424) and anomalous gold > 0.1g/t over the strike length. A total of 9 samples were taken at the Glacier Epithermal Trend.

The Rust epithermal system has also returned exciting assay results and highlighted a 100 m E/W structure with anomalous uranium and copper, with values up to 0.4% U3O8 and 0.54% Cu (sample F005613). The structure passes through phyllic altered andesites and andesitic volcanic breccias with sporadic tourmaline cemented breccias. The Rust target lies just 700m south of the Glacier Gold vein system and attests to the prospectivity of the region. A total of 12 samples were taken at the Rust target.
