The Skal uranium deposit is located 30km north of Mount Isa.
The Skal deposit contains a number of ore lenses which are concentrated in four zones within an area of approximately 2km². The mineralised lenses that comprise Skal vary in strike from 035° to 045° and dip steeply from -85°E to -75°W. Individual lenses can be up to 50m thick and have a combined strike length of over 1,300m. High grade intervals are associated with quartz veins within brecciated and albitised siltstones and basalts. The deposit area is structurally complex, and orebodies are truncated and offset by faults.
The current Skal Mineral Resource is stated in the table below. The Mineral Resource estimate was undertaken using Kriging methodologies with search radii dependant on variography results and drill hole spacing. Approximately 72% of the dataset was derived from downhole radiometrically logged equivalent U3O8 grades. The remainder was from geochemical assays. Downhole logging was carried out using Company owned and calibrated equipment, with derived grades being validated against assays in a number of drill holes. All recent holes were downhole surveyed for deviation and collars were located using a DGPS .
