In Carpentaria's ongoing search for economic copper ore at the Waukaloo copper prospect, that could possibly extend downdip beneath its earlier completed percussion drillholes PDH12 and PDH18, the drilling of the first of three appraisal diamond holes (DDH Waukaloo 1 to TD 459.6 m) over the period October-December 1973 encountered minor, scattered blebs of chalcopyrite throughout the drill core, with 1 metre split samples from the central section of the hole assaying over 1% Cu. Elsewhere, exploratory drag bit drilling to test for extensions of the 'Waukaloo Copper Horizon' within EL 85 and the adjoining EL 62 was successful in outlining this unit at distances of up to 10 km away from the main prospect. Following Minad-Teton Australia's successful discovery in 1972 of the Honeymoon uranium deposit at their South Eagle prospect, activities were directed towards assessing the electrical resistivity depth sounding method as a cheap way of defining the distribution and depth of target palaeochannel sediments. In addition, all of the earlier uranium exploratory drillholes completed by MTA and Carpentaria Exploration in the north-eastern portion of the EL area, plus local surface topographic features, were levelled and located to accuracies of +/- 0.2 m and +/- 0.1 m respectively, while twelve subsiduary survey control points were established over the mineralised palaeochannel area to aid in accurate siting of future drillholes. A post-discovery re-examination of the lithological and geochemical factors affecting the genesis of Frome Embayment palaeochannel uranium accumulations concluded that localised depositional factors, such as the abundance of pyrite and carbonaceous material, has played a major role in the deposition of secondary uranium from migrating oxidized uraniferous solutions. A detailed surface resistivity survey was carried out at South Eagle during February 1974, using an expanded Schlumberger Array to obtain electrical soundings over marginal parts of the mineralised palaeochannel, where existing drillhole density is low. The survey was able to define the eastern and western banks of the channel and to detect a subtle resistive response which may reflect the abundant pyrite associated with the uranium ore. Depths to crystalline basement, however, were over-estimated by around 24% due to the effects of conductive near-surface overburden. A preliminary ore reserve has been calculated for the Honeymoon deposit by Teton Exploration Drilling Co., based on its proprietary in-house evaluation of the drillhole gamma ray logs. An estimated 3 million lbs of uranium oxide averaging 0.37% U is currently thought to be present in the channel sands, but this tonnage and grade figure is obviously a guide only, and will later be revised to lie nearer the truth when representative coring of the mineralised zone has been carried out.
