Drilling results extend broad gold zone at Old Red Hill
[email protected]
28 July 2006
ASX Code : HEG, HEGOA
The recently completed Stage 2 drilling program at the Red Hill project has
intersected a broad zone of near surface gold mineralisation and has extended the
Old Red Hill mineral resource area. Results have confirmed the continuity of a wide
zone of gold mineralisation previously drilled in hole RC32 which intersected
2.52g/tAu over 30 metres from surface (including 6.54g/tAu over 8 metres).
The Red Hill project is located over a zone of gold mineralisation and old high grade
workings of three kilometres in strike length and 50 to 100 metres in width, along the
eastern flank of the Hill End Anticline to the north of Hill End, New South Wales,
Australia. The company has almost the entire fifty kilometres strike length of the Hill
End Anticline under tenement.
In the Red Hill project area, deep weathering to a depth of 70 metres and gently
undulating topography is ideal for open pit development.
Reverse circulation drilling has targeted gold mineralisation in the weathered zone
above the water table with significant intersections including the following results:
RHRC88 with 1.94g/tAu over 20 metres from 27 metres;
RHRC89 with 2.83g/tAu over 9 metres from 32 metres;
RHRC90 with 2.04g/tAu over 25 metres from surface; and,
RHRC91 with 1.36g/tAu over 20 metres from 6 metres.
The Old Red Hill vein set, which is now outlined by shallow drilling over a 200 metres
strike length and up to 27 metres width, is located five kilometres along strike from
Hawkins Hill and Reward deposits. It occurs in a similar geological setting to
Hawkins Hill and Reward with gold in bedding and spur quartz veins in en echelon
vein sets, which are interpreted to continue down plunge for a kilometre or more.
Four shallow-plunging vein sets have been identified to date in the southern Red Hill
area over a near surface strike length of 800 metres: Whites, Red Hill Deeps, Old
Red Hill and Marshall-McMahon. Additional areas along strike in the northern Red

Hill area, which are yet to be drilled, are the Valentines, Emily and Old Company
workings.
Further drilling on the Old Red Hill vein set is planned down dip and down plunge of
the current drilling, and previous drilling by BHP in 1989 will be re-drilled since it is
likely that the BHP drilling, sampling and assay methods have resulted in a low bias
in the assays received.
Previous metallurgical testing of oxide, transitional and primary samples from Red Hill
indicated excellent gold recovery using simple gravity and leach processing at a
relatively coarse grind. In summary, for all mineralisation categories:
•
•
•
gold appears to be free gold and liberated at a maximum particle size of 212
microns;
gravity gold recovery averaged 77% and the remainder leached quite rapidly
over approximately six hours;
the total gold extraction for all samples was 98-99%.
A review of mining parameters has indicated that the weathered zone to
approximately 60 metres is quite soft for excavating and the wide mineralisation will
result in a low stripping ratio.
A new resource estimate for Old Red Hill near surface mineralisation will include the
planned infill and extension drilling. The previous inferred and indicated mineral
resources estimate for the Red Hill area was done in 2004 and totalled 27,000
ounces of oxide and transition material in Whites and Old Red Hill (inferred resource
of 8,600 ounces in oxide material).
Some assay results are awaited for the Stage 2 drilling program at Red Hill which
included 1,879 metres of reverse circulation drilling and 655 metres of diamond
drilling in 31 holes. Further details will be reported at a later date. Reverse
circulation drilling samples with visible quartz samples and diamond core samples
were assayed with the screen fire assay technique. Visible gold was observed in
several core samples with grains to 1mm.
