Western Gawler Project (DYL 50% can earn
100% of uranium rights)
In February 2006 DYL reached agreement with
Dominion Gold Operations Pty Ltd, a wholly owned subsidiary of
Dominion Mining Limited (Dominion) to acquire the uranium
rights (100%) to seven exploration licences covering 5,706 km2
in the Western Gawler Province.
Despite being relatively unexplored, the
Tertiary palaeochannel systems in the district are known to
host several uranium deposits including the Yarranna 1-4
Deposits (Narlaby Palaeochannel) and the Wynbring, Ealbara and
Warrior Deposits (Kingoonya Palaeochannel). Indications of
anomalous radioactivity are widespread within the region with
uranium mineralisation believed to have been derived from the
weathering of crystalline Proterozoic rocks and emplaced at
suitable redox boundaries within the overlying sedimentary
cover. In general, palaeochannel and mineralisation style
resembles that seen at Honeymoon (Curnamona Province) where
mineralisation is hosted by carbonaceous Eocene sands and
blanketed by Miocene clays.
In September 2006 DYL flew an airborne
electromagnetic (AEM) survey over the main tenement block
south of the Challenger Mine. The AEM survey data provided
excellent definition of palaeochannels ahead of a planned
aircore drilling programme.
Following clearance for its drilling programme
from the Antakirinja Matu - Yankunytjatjara Native Title
Claimants in early June, Deep Yellow commenced an initial pass
of Aircore drilling with 145 holes for 9,856 m being drilled.
These holes were sited along existing lines of access or where
natural access permitted. Hole spacing varied from 500 m to 1
km, with hole depths ranging from 80 to 110 m.

Drill Traverses
Lithologies intersected included surficial
channel sands; carbonaceous-lignitic clays; basinal clays,
claystones and various metamorphic basement rocks. Most holes
were radiometrically logged downhole and drill cuttings
scanned with a hand-held scintillometer.
All of the targeted paleodrainages received
some drill coverage, with the Mulgathing tributary of the
Anthony Paleochannel receiving most attention. Only low order
radiometric anomalism was detected. Assay results returned
best values of 2 m at 43 ppm U3O8
(Challenger Channel) 4 m at 22 ppm U3O8
(Lake Anthony South Channel) and 2 m at 26 ppm U3O8
(Mulgathing Trough area). Whilst these values are low, the
associated host rocks are considered prospective and worthy of
further drilling in order to try and locate lignite hosted
mineralisation and/or sandstone hosted roll front uranium
mineralisation.

In June 2008 a meeting was held with the Maralinga-Tjaruta
Council with respect to access for drilling to EL's 3092 and
3093. Negotiations are still progressing.
