Angela
and Pamela Uranium Deposits
Reports and data
held by Geoscience Australia
The
following drill-hole data files, cross-sections and reports on the
Angela and Pamela uranium deposits, 28 km south of Alice Springs, were
initially submitted by Uranerz Australia Pty Ltd to the Australian Government (Australian
Atomic Energy Commission) in the early 1980s.

volumes containing data on
equivalent
uranium grades for mineralised intersections measured by Uranerz
Australia Pty
Ltd.

:: Supplementary
information to uranium resources evaluation, Angela area
Uranerz Australia Pty Ltd, 1983. Supplementary
information for the Bureau of Mineral Resources on the Angela 1 deposit
and
Angelas 2 to 5 prospects, Alice Springs, Northern Territory.
The report provides background information to the evaluation of uranium
resources at the Angela deposit. The exploration history from 1972 to
1983, geology, mineralisation and methods used to calculate grades are
described.
:: Processing of radiometric borehole data - summary of
discussions
Summary
of
discussions with Uranerz Australia Pty Ltd on methods used
to process
borehole
radiometric logs from the Angela deposit NT. Report to Bureau
of
Mineral Resources, 1984.
Prior
to 1980, equivalent uranium
grades of mineralised intersections were derived from down-hole gamma
ray probe
measurements using the ‘area under the curve’
method. After 1980, the Uranerz
geophysicists used the ‘deconvolution (or inverse
filtering)’ method to
estimate equivalent uranium grades. All radiometric grades were later
recalculated
using the deconvolution method.
