Westmoreland

(U3O8 Limited 100%)

  • Major detailed radiometric survey recently completed.
The Westmoreland project consists of three tenements (3 applications) and is located immediately east and north-east of the Westmoreland Uranium deposits situated approximately 400 kilometres north-west of Mount Isa, Queensland. The Carpentarian Westmoreland Conglomerate of medium and coarse argillaceous sandstone with conglomerate lenses intruded by north-east trending dolerite dykes, which, at Redtree and other Westmoreland deposits (Westmoreland total Inferred Resource 17.4 million tonnes @ 0.12% U3O8), show brecciation, shearing and are extensively altered with reddish haematite particularly along contact zones. The primary ore mineral in the Westmoreland Conglomerate is pitchblende.

The targets on the project area are hard rock uranium mineralisation in the eastern continuation of the Westmoreland Conglomerate, and roll front / palaeochannel situations in the Cainozoic sands further east and north-east, analogous to those in the Frome Embayment of South Australia, where the Beverley and Honeymoon deposits are found.

Westmoreland
Westmoreland East - Geology and Prospects
 
Two known hard rock occurrences in extensions to the Westmoreland Conglomerate are known within EPM 14964 at Buck Hill and Buck Hill Fault:

Buck Hill Fault Large silicified sandstone fault breccia length 915m, maximum width 39m. High radioactivity noted on boulders of scree slop where torbernite gave 2,500 c/m.
Buck Hill Area Pebbly, conglomerate quartz sandstone. Surface sample 0.02% U3O8. Torbernite & autunite in phosphatic lenses. Counts were 300-500 c/m, compared to background 50 c/s.


The Cainozoic sands have been tested by very widely spaced drill holes which confirmed anomalous radioactivity. The drilling showed that although much of the Cainozoic sequence in the tested area was dark grey to black clay with scattered bands of gypsum and pyrite / marcasite nodules, gamma-ray logs indicates that there are anomalous zones in the uranium channel, correlating with either sandy bands or gypsum bands. Further follow up of sandy units is warranted to establish the presence of palaeochannels.

U3O8 Limited has recently completed a major airborne magnetic and radiometric survey over the three tenements making up the project area. Results of the survey are still pending but it is expected that drill holes can be positioned on anomalies that will be generated.
