De Grey Mining Limited (ASX: DEG, “De Grey”, “Company”) is pleased to provide the following drilling
update at the Hemi Gold Discovery, located approximately 60km south of Port Hedland in Western
Australia.
The Falcon intrusion is located approximately 600m west of Brolga and immediately south of Aquila.
Strong mineralisation has been defined over a strike length of approximately 1km (Figure 1). The
bedrock mineralisation is covered by approximately 40m of transported material. This cover is similar
to the Aquila, Brolga and Crow deposits.
The mineralisation at Falcon is intimately associated with highly brecciated and extensively sulphide
altered portions of the north-south orientated subvertical intrusion. The style and intensity of alteration
and brecciation is similar to the nearby Aquila deposit.
Significant new gold results in drilling are provided in Table 1 and Figures 1 – 5.
RC and Diamond Drilling
Falcon has now been tested with RC and diamond drilling to 80m x 40m spacing and a maximum
vertical depth of approximately 280m. The drilling demonstrates thick zones of gold mineralisation
within an intrusion up to 100m thick, 350m down dip and over 1,000m of strike. Mineralisation dips
steeply to the east and remains open at depth along the entire strike length.
The recent deepest holes occur on most 80m spaced sections and have intersected significant
mineralisation including:
− 26.3m @ 2.3g/t Au from 309m including 5.7m @ 4.4g/t Au from 325.3m in HERC298D,
− 34.2m @ 1.8g/t Au from 212m including 4.0m @ 4.1g/t Au from 218.0m and 7.0m @ 3.7g/t
Au from 230.0m in HERC407D,
− 65m @ 1.4g/t Au from 324m including 0.5m @ 17.3g/t Au from 330.0m in HERC416D and
− 55m @ 1.0g/t Au from 263m including 3.5m @ 3.6g/t Au from 298.0m and 16.5m @ 1.1g/t
Au from 324.5m in HERC400DW1.
A footwall lode below the main lode is becoming better defined and includes:
− 20.1m @ 1.0g/t Au from 324m in HERC402D
− 20.9m @ 1.9g/t Au from 369min HERC299DW1 (previously reported).
Additional footwall lodes are becoming apparent in deeper drilling, as the intrusion thickens at depth.
At Falcon, the next phase of drilling includes 160m spaced step out diamond holes to test the main
mineralised zone at a vertical depth of around 450m and will be extended to test the new footwall
lodes. This work has the potential to further significantly expand the gold endowment at Falcon.
The Falcon intrusion extends for at least another 2km to the south. Drilling across this area to date
has not defined significant mineralisation. However, the bulk of this work is wide-spaced, shallow
aircore drilling and further drilling to effectively test this zone in more detail is required.
