Mt Isa District Tenements
Within the Mt Isa district DYL carries out
exploration on its 100% owned tenements and on two joint
venture areas. In agreement with Matrix Metals Ltd, DYL can
earn the rights to 100% of the uranium within Matrix's
extensive tenement holding to the north and north-east of Mt
Isa and to the south of Cloncurry. DYL is currently earning
into the first tranche of the agreement, namely a 51% interest
in the uranium rights. Exploration is well advanced on various
tenements with two prospects (Miranda and Conquest) returning
encouraging widths and grades of uranium mineralisation from
RC percussion drilling.
In agreement with Mt Isa Mines Ltd, part of
the Xstrata Group DYL can ultimately acquire 100% of the
uranium rights over a project and immediately west of the Mt
Isa minesite (ASX 21 January 2008). Exploration programmes
commenced in March 2008 and targets have been developed for
drilling.
Queens Gift Prospect - Prospector EPM
15070 - DYL 100%
The Queens Gift Prospect is located 70 km
north of Mt Isa within EPM 15070. Surface mapping and sampling
by DYL outlined a uranium mineralised zone up to 50 m wide
over 1,300 m strike with a best surface composite rockchip
sample assaying 2.86% U3O8.
Previous diamond drilling by Queensland Mines Ltd (QML) in
1969 and by Agip Nucleare Australia Pty Ltd (Agip) in 1974 was
all completed above 50 m vertical depth.
Some significant intercepts included:
-
QML 2 - 4.57 m at 5,840 ppm (0.584%) U3O8
from 71.63 m
-
QML 3 - 6.10 m at 830 ppm (0.083%) U3O8
from 32.31 m
-
Agip 1 - 21.0 m at 470 ppm (0.047%) U3O8
from 41.0 m
-
Agip 2 - 4.0 m at 1,020 ppm (0.102%) U3O8
from 72.25 m
-
Agip 3 - 3.0 m at 900 ppm (0.090%) U3O8
from 61.80 m
An RC percussion drill programme totalling 47
holes for 4,930 metre was carried out over 800 m strike of the
outcropping area of the 1.3 km strike radiometric anomaly with
the best results coming from the Central and North anomalies.

Uranium mineralisation is hosted by altered
(albitisation) basalts with quartz hematite breccia zones
locally developed through the alteration zone. This
metasomatic style of mineralisation is common within the Mt
Isa district with the best example being Summit Resources
Ltd's Valhalla uranium deposit (JORC Code 2004 compliant
resource estimate - 25,970 tonne U3O8).
It is important to note that within some of
the wider 400 ppm U3O8
intercepts, intervals with average grades in excess of 700 ppm U3O8
occur which approximates the resource grade of the Valhalla
deposit. Uranium mineralisation is associated with intense
hematite-magnetite alteration with a sharp western and a
gradational eastern contact.
Within the North anomaly the deepest
intersection is 11 m at 585 ppm U3O8
from 119 m downhole the centre of this intercept is 95 metre
below surface with mineralisation being open to depth.
Significant assay results from the drilling are highlighted

Hole QGDC001
Queens Gift Diamond Drilling
As follow-up to the 2007 RC percussion drill
programme a total of six diamond holes for 969 metre was
completed (including one abandoned hole) (ASX 21 August 2008).
Assay results have been received from three of
the six drill holes. QGDC001 was drilled to determine the
extent and orientation of the mineralised zone that was
encountered by 2007 RC percussion drilling. Mineralisation was
intersected down-plunge of previously reported holes DQRC0032
and DQRC0033. The mineralised zones are foliated and often
brecciated with pervasive hematite and carbonate alteration
(see photograph of core).
Holes QGDC002 (an undercut of DQRC0047) and
QGDC006 are located 200 metres and 300 metres south of QGDC001
respectively and intersected similar styles of mineralisation
as in QGDC001, confirming previous RC percussion drill
intersections.
Further diamond drilling and RC percussion is
planned for the Queens Gift Prospect area later in the field
season following priority drill programmes on the Ewen and Isa
West Project tenements.

* XRF Chemical Assays
The Directors consider that these early
results from Queens Gift indicate the prospect has the
potential to host an economically viable uranium deposit.
NW QUEENSLAND JOINT VENTURE (Matrix Metals Ltd)
DYL commenced exploration on the joint venture
tenements in November 2006 with RC percussion drill programmes
over the Lochness and Miranda Prospects. In August 2007 DYL
undertook the first of two helicopter supported reconnaissance
mapping and sampling programmes over the extensive joint
venture tenement holdings (ASX 5 October and 13 November 2007)
which resulted in the delineation of drill targets throughout
the tenements with the main cluster being within the EPM 14916
(Ewen) located 85 km north of Mt Isa.

Ewen Project EPM 14916 Prospect Locations
An initial and limited RC percussion drill
programme on its Conquest Prospect returned highly encouraging
assay results (ASX 2 January 2007). Previous exploration in
the prospect area was carried out by Mineral Deposits Limited
and Agip Nucleare (Agip) in the 1970s. Agip drilled 7 holes
for 553 m however selective assaying of drill core by Agip
returned only narrow intercepts the best being 4 m at 1,210
ppm U3O8.
Significant wide intercepts at Conquest were
returned by DYL in late 2007 namely:
As follow-up to the 2007 results, the 2008 RC
percussion drilling programme commenced in late July.
XRF chemical assay results from the drilling
(holes DCQRC008 - 010 drilled on the DCQGRC006 section)
confirm mineralisation over approximately 25-30 metres true
width at shallow depth. The intersections of 14 m at 1,008 ppm U3O8
and 12 m at 592 ppm U3O8
in hole DCQRC010 are very
encouraging and are typical of the Valhalla and Queens Gift
style of uranium mineralisation. Holes DCQRC011 and 012
drilled 20 m to the north of the main zone intersected
narrower and lower grade mineralisation. The main intersection
is open to the south and will be drilled shortly.

* XRF Chemical Assays
A 2008 RC drill programme comprising 113 holes has been
designed to test the Ewen Prospects. An initial
programme of 75 holes will commence on 25th July with the
balance of the programme being results driven.
Within EPM 14281 (Miranda) uranium
mineralisation is hosted by chloritic shear zones developed
through granite.
Some of the wider intercepts returned
indicate that the Miranda Prospect has tonnage potential and
that further drilling in the 2008 field season is warranted.
Significant Miranda Prospect intercepts
include:
NW QUEENSLAND JV - Regional Exploration
In the Mt Cuthbert area within EPMs 14282 and
11025 uranium mineralisation is associated with granitic
rocks and felsic intrusives. At Anomaly 78 - Warwick,
the highgrade samples assaying up to 1.17% U3O8
were collected
over 80 m strike and are associated with narrow
chlorite-sericite schist zones and more 'mafic' layers within
the felsic rock similar to the mineralisation at the Miranda
Prospect to the south. Elsewhere in the district granitic
outcrops have returned anomalous uranium values and have been
designated for follow-up in 2008.
To the south of Cloncurry rockchip sampling of
airborne radiometric anomalies within the JV tenements
returned numerous elevated uranium assays. Most of these
anomalies lie along linear northwest trending fractures and
lithologic contacts within pelitic sediments. Typically these
features form ferruginous/siliceous ridge tops and are often
coincident with small copper shows. Several of these
structural linears or corridors have recently been
drill-tested for copper-gold mineralisation by Matrix,
particularly along the Sierra, Greenmount and Leopard Lines.
Most of the uranium anomalous samples comprise
highly leached ferruginous/gossanous lode material,
registering as only modestly radioactive with hand-held
scintillometers. Some anomalies occur in sheared metasediment
adjacent to siliceous/ferruginous ridgetops. The exception is
sample WR 004 -Toby Barty, taken from a small copper working,
which exposed visible torbernite in relatively fresh
siltstone. This sample returned 1.14% U3O8. A percussion hole
drilled directly beneath this site, returned 400 ppm U3O8
from
a one metre sample registering only 2 x background. Although
rather spotty and discontinuous, many of these ground-checked
anomalies warrant follow-up radiometric surveying and downhole
probing of available percussion drillholes.
The results from the sampling programme in the
Cloncurry area compliment Matrix's extensive uranium anomalous
database which formed the basis for DYL's initial move into
the 'Mt Isa Province'.
ISA WEST PROJECT (earning 100% of uranium rights from Xstrata)
As previously announced to the ASX (21
January, 2008) DYL reached agreement with Mount Isa
Mines Limited (a company within the Xstrata Group) (Xstrata)
whereby DYL may (subject to a number of conditions)
ultimately acquire 100% of the uranium rights over six (6)
tenements held by Xstrata. The tenements cover a total
of 504 km2 immediately west
of the Mt Isa townsite/minesite.
The six Exploration Permits for Minerals
(EPMs) are known collectively as the Isa West Project and
importantly they cover extensive basalt and sediment sequences
of the prospective Haslingden Group which hosts the Valhalla
and Skal (Summit/Paladin) and Queens Gift (DYL) uranium
deposits.

Isa West Regional Geology and Tenement Locations
The study of historic uranium (and base metal) exploration
reports confirmed a cluster of uranium prospects hosted by
Haslingden Group basalts and sediments. Mapping and sampling
of the prospects has been completed and assay results tabled
below.

Uranium Anomalies Isa West Project
At two of the historic prospects shallow
shafts were sunk and material mined in the 1950s. Historic
trenching results include:
- 3 m at 1,450 ppm U3O8
- 5 m at 3,300 ppm U3O8
- 8 m at 800 ppm U3O8
and
- 5 m at 3,600 ppm U3O8
Several of the 1970's trenches have been
selectively resampled and prospected using a handheld
spectrometer to confirm mineralised zones.
XRF chemical assay results have been received
for (horizontal) composite channel chip samples from the
resampling of 'mineralised zones' within 1970s backhoe
trenches (see ASX 23 July and 21 August 2008).
At the Folderol North and South Prospects
located within EPMs 13098 and 12886, the best interval
returned (Folderol North) was from a zone of
hematite-magnetite altered chloritic schist (sheared basalt)
over 3.5 m assaying 3,409 ppm U3O8.
At Folderol South best assays were 2 m at 5,700 ppm U3O8
and 2 m at 4,100 ppm U3O8.
The best interval returned at Mothers Day was
from a zone of magnetite altered dolerite containing patchy
visible uranophane mineralisation over 4 m and assaying 8,557
ppm U3O8.
At Turpentine best assays were 3 m at 1,414 ppm U3O8
and 6 m at 1,031 ppm U3O8
from epidote altered chloritic schist.

* Datum MGA Zone 54 / GDA 94
Based on the assay results and ground
radiometric survey data an RC percussion drill programme has
been designed to test the mineralised targets at depth. The
prospects covering an area of 6 x 2 km have been cleared for
drilling by the Kalkadoon Traditional Owners.
