Description

Adavale Resources Ltd (Previously PocketMail Ltd) is an uranium exploration company with projects in Queensland and South Australia. In QLD the company has an interest in the Springvale Project and in SA the company has an interest in the Lake Surprise project.

LAKE SURPRISE

The Project Area is in South Australia, is situated 550 Km north of Adelaide, 70 Km East of Marree and covers 2705 Km2 on the northern flank of the Flinders Ranges. The Lake Surprise tenements cover an area that is prospective for surficial and sandstone style uranium mineralization. Strong radiometric anomalies occur in the Project area and uranium minerals have been found. Known uranium orebodies on the eastern side of the Flinders Ranges include Beverley, Honeymoon, Goulds Dam and Yarramba and the Mt Gee project lies in the northern Flinders Ranges about 60 Km from the Lake Surprise Project area. Rocks of the Flinders Ranges and surrounding areas are highly uraniferous and it is amongst the world’s most prolific uranium provinces. The targets are surficial uranium ore bodies in a number of suitable host rocks, and roll front style orebodies developed in both Tertiary and Mesozoic host rocks. A model similar to that being used by Eromanga Uranium is applicable to the Project area. The standard roll front model only considers reducing-oxidation (redox) conditions in relation to the solubilisation and the precipitation of uranium. The proposed model incorporates additional physico-chemical processes that influence the equilibrium between soluble and precipitated uranium. It also incorporates the input of uranium and other chemical species from artesian springs.

SPRINGVALE

The Project Area is in South West Queensland, situated between Boulia and Bedourie and covers 3000 Km2 of the flat lying uraniferous weathered Toolebuc formation which occurs at shallow depth throughout the area. The Springvale tenements cover an area that is prospective for sedimentary uranium mineralization. Huge volumes of the Toolebuc Formation have been eroded in the Springvale Project and surrounding areas and the uranium vanadium and molybdenum released from the Toolebuc have moved through the Hamilton – Georgina River system. The area is also prospective for "mound spring model" precious metal orebodies and several other commodities including rare earths and diamonds. The targets are uranium roll front style orebodies developed in and adjacent to the weathered Toolebuc formation and in the channel sediments of the Georgina-Hamilton river system. The Toolebuc formation contains significant uranium vanadium and molybdenum and occurrences of uranium minerals are known in the Project area. Airborne radiometric surveys show large areas of strong uranium channel radiation, and logged stratigraphic drill holes in the area show pronounced gamma radiation anomalies. The area has alkaline carbonate water mound springs that are expected to facilitate the leaching and transport of uranium, and the weathered Toolebuc Formation is a source of large quantities of vanadium. These factors increase the likelihood of the formation of uranium orebodies. The vanadium and molybdenum in the oxidised Toolebuc Formation have been exploration targets in the past and major Vanadium/ Molybdemum resources are being outlined. Metallurgical test work has shown that vanadium and molybdenum are subject to leaching with both acid and alkaline leachants which opens the possibility that a uranium orebody in the Project area could be amenable to alkaline in-situ leaching with recovery of uranium, vanadium and molybdenum.
