Westgold Resources Limited (ASX: WGR)
ASX RELEASE
9 JUNE 2009
Rover 1 Drilling Update
Exciting New Zones Discovered
- Two new mineralised zones
discovered to the west of previous drilling indicate potential for
significant extensions to the large-scale Tennant Creek Style system
- Strong Copper-Gold-Cobalt-Bismuth mineralisation
now defined over 500m strike length and within an 800m long magnetic and
gravity target
- Second diamond drill rig commissioned to target immediate
extensions of new zone before utilisation
on new regional targets ~ drilling scheduled to commence on 18 June
Following
the successful completion of a $5.7M Rights Issue and the commencement of 2009
drilling season, Westgold provides the following update
on progress at the Company’s Rover
1 Project, located in the Northern Territory.
The
drilling programme, which consists of both Reverse
Circulation (RC) and diamond drilling, is progressing well. RC drilling
commenced in mid-March, where 27
pre-collars for a total of 6,240m have been completed. The RC drilling allows for the rapid penetration
through the barren cover sequence and provides effective and rapid access for
the subsequent diamond drilling programme.
Diamond
drilling commenced in early April and is also progressing well with 7 diamond ?tails? for a total of 2,104m completed to date. Results for the
first three holes have been received and most importantly, have discovered two new zones of mineralisation, 250m to the
west of previous drilling. Results for hole WGR1D018 include:
Ironstone Hosted 53m @ 0.5% Cu, 0.03g/t Au, 0.3g/t Ag, 02% Co from 446m
(including 8m @ 1.2% Cu, 0.09g/t Au, 1.0g/t Ag, 0.06%Co)
Stringer Zone 18m
@ 1.2% Cu, 0.71g/t Au, 3.1g/t Ag, 0.15% Bi, 0.15% Co from
536m
(including 8m @
1.6% Cu, 1.2g/t Au, 4.9g/tAg, 0.23% Bi,
0.19% Co)
These
two new zones of mineralisation add an exciting new
dimension to the scale of this large Tennant Creek Style system with strong
Copper-Gold-Cobalt-Bismuth mineralisation now defined
over a 500m strike length and within an 800m long magnetic and gravity target.
The
mineralisation occurs within a 75m wide (true width),
well-developed magnetite-rich ironstone and intense chlorite alteration zone.
The strongest copper and gold (18m @
1.2% Cu, 0.71g/t Au) are hosted within the chlorite-rich alteration in a brecciated and veined Stringer Zone which
typically hosts the-high grade gold mineralisation
250m along strike to the immediate east. The massive magnetite-rich ironstone
portion also hosts further copper mineralisation with
53m @ 0.5% Cu from 446m including 8m @
1.2% Cu.
In
light of the Company’s recent exploration success, Westgold
has scheduled a second diamond drill rig
to commence on 18 June. This rig will target immediate extensions to this
new zone and potential high-grade gold structures before utilisation
on new regional targets.
Drill
hole WGR1D013 which targeted the eastern most limit of
drilling, immediately below the previously reported high-grade copper zone (65m
@ 2.6% Cu, 0.09g/t Au) has
intersected a broad 90 metre wide (true
width), magnetite-rich ironstone and chlorite alteration zone with the
following results:
52m @ 0.72% Cu, 0.07g/t Au, 0.8g/t Ag, 0.02% Bi, 0.04% Co from 446m
(including
12m @ 1.7% Cu, 0.06g/t Au, 0.9g/tAg, 0.01% Bi,
0.02% Co); and
17m @ 0.44% Cu, 0.19g/t Au, 1.0g/t Ag, 0.01% Bi, 0.05% Co from 503m
Further planned drilling beneath this zone will
target an interpreted high-grade gold zone based on geological interpretation
and strong vertical zonation. This zonation
is seen in holes immediately to the west within the Rover 1 system and is
evident at many other Tennant Creek style orebodies.
No significant results were received from hole WGR1D014.
Progressive geological logging of the next four
diamond holes shows further typical Iron Oxide Copper-Gold (IOCG)
magnetite-rich and hematite ironstones and associated intense chlorite
alteration zones together with variable visible copper and/or
bismuth mineralisation. Assay results for these holes remain pending and Westgold
expects to provide these results, as well as further updates on its drilling
progress in the June Quarterly Report.
