Benmara, Northern Territory,  Australia

PD is farming into two exploration licences held by Lagoon Creek Resources Pty Ltd, a wholly owned subsidiary of Laramide Corporation of Canada which owns the Westmoreland uranium deposits in north-west Queensland. The project is located on pastoral leasehold land in the Northern Territory, where uranium mining is permitted.

Geologically, the properties cover a series of targets which appear to have very similar characteristics to the Westmoreland uranium ore district but are beneath post-ore cover. In the Westmoreland deposits (Figure 1), uranium mineralisation is located within the Westmoreland Conglomerate on the margins of dolerite dykes and sills and of the basaltic Siegal Volcanics. Ore formation at these locations is interpreted to have occurred because oxidising uranium-bearing ore fluids passing through faults and the Westmoreland Conglomerate, have come into contact with reduced iron in the volcanics and dolerite, causing the uranium to be deposited.  At Benmara, unlike Westmoreland, the targets are all beneath younger Cambrian sandstone cover of variable thickness which PD interprets to be around 100m on average. PD believes that no exploration company has drilled holes into any of these Westmoreland-type targets before.

Interpretation of the aeromagnetic data over the area, along with geological mapping, has indicated that the Westmoreland Conglomerate and Siegal Volcanics are both present within the EL. The Murphy Inlier basement rocks are known to be uranium-bearing and, as at Westmoreland 120 km to the east, are a potential source for the mineralisation that occurs in the overlying stratigraphy.   A uranium vein occurrence (known as Anomaly 1) within the Murphy Inlier basement rocks provides further evidence that uranium-bearing ore fluids have passed through the area.

A number of targets which appear to be similar to those in the Westmoreland district have been interpreted. The highest priority is on the margins of an interpreted (concealed) north-east trending dolerite dyke. From the magnetic data, it is interpreted to be much thicker than the north-east trending dyke at Westmoreland and, as such, may represent a significant potential chemical “trap” zone.  In the event that a large volume of uranium-bearing ore fluids have flowed along or across its contact with the Westmoreland Conglomerate, it has the potential to host a large uranium deposit.  As at Westmoreland, it is suggested that the dolerite mineral chemistry may have interacted with a uranium-bearing fluid as it passed through the dyke contact, depositing uranium mineralisation. The northern end of the dyke is interpreted to be in contact with the Siegal Volcanics, presenting a similar setting to the Westmoreland deposits themselves (see Figure 2).

A number of other targets with characteristics similar to other uranium prospects in the Westmoreland district have been identified.

PD regards this property as highly prospective for a Westmoreland-style uranium deposit. The targets are particularly suited to the PD methodology because detailed geophysical surveying may be used to interpret the geometry of the target dolerite and the Siegal Volcanics contacts. Then PredictoreTM fluid modelling technology can be used to identify high quality drill targets. This will allow PD to maximise its chances of success with specifically targeted drilling.
