    Hello Everyone and T.M.,Please refrain from a panic style of Postings.

    The following Quote from www.nru.com.au proves right those postings which I submitted in the past regarding hearing in approx. 1962 that the Harts range was a Hot Uranium Area.Quote:-/

    The dominant feature in the Qtz Hill region is the granites of the Entia (and the inset Huckitta) Dome, which intrude and deform dominantly felsic gneisses with small amounts of mafic and ultramafic volcanics. Fractionated, garnet bearing pegmatites and small mafic lenses intrude the gneisses, and a dominantly ?sodic alteration pervades and degrades the mafic intrusions.

    A major structural suture (palaeo-subduction) zone exists to the north of the project (see fig. 5, in Geophysics), and the rim of the Entia dome is interpreted to be a major deep-crustal feature.

    Exploration History

    Pacific Nuclear Corporation (PNC) explored Quartz Hill in 1992. Prior work to that had been poorly recorded mica mining from the depression era, with re-opening of the mica mines allegedly using POW labour during the war. Many of the Italians who had worked here during the war may have returned in the post-war era, as the anecdotal evidence from prospectors and station managers in the area is that much of the post-war work in what would have been very isolated, primitive and remote camps was carried out by the newly immigrated Italian community.

    Some geological work had been done on the mica mines however, as PNC report that one of the mica mines on the Qtz Hill project was known to contain uraniferous minerals. This was probably related to the burst of exploration for uranium that occurred shortly after the war in the 1950’s.

    PNC initially flew airborne radiometrics, and followed up the data in 1993-4. This resulted in the discovery of what is now known as Quartz Hill and Spartacus.

    Quartz Hill was a priority 1 anomaly on the “quartz blow” outcrop known as Quartz Hill. Ground checks located hotspots within soil and quartz scree and on the pegmatite vein near the spur of the ridge, and a small hole was blasted on the pegmatite. Copper has been indicated on the Geol Survey map at Quartz Hill but PNC found none, whereas they located uranium rich samarskite intergrown with uraninite and coffinite, with some alteration to uraniferous tanteuxenite. Samples were in what they reported as “brecciated pegmatite”.

    Felspar (part of the Spartacus area) was a strong anomaly caused by float of a uranium rich mineral associated with a large E-W pegmatite. The mineral was massive, black, glassy, had a conchoidal fracture and didn’t show weathering. It was identified as a Y-Nb>U mineral of the fergusonite series plus alteration products./End Quote

    The Areas, which the Quote from NRU mentions are very close (and may actually join) THR's Areas in the Harts Ranges.
    I t is possible that BTV by been early on the Scene in the Harts Ranges obtained the most Prospective Areas which in due time became THR's Areas.
    I guess Conix will be able to add to this Posting.

    Enjoyable research to all,
