WIDTH OF MINERALISATION INCREASING
Ra zone mineralisation has averaged 400m in width,
a considerable increase to the 90m experienced in the Amun zone.
As reported in October 2002 the company engaged Stanley Mining Services to begin
drilling the Ra Zone at Sukari with the intention to add to the existing
2,040,000 oz resource of the Amun zone. Two Stanley Rigs were added to the
company's three existing rigs on October 13th and the company expects to drill
its 300th (Sukari Diamond Drill Hole, SDDH300) this month. Stanley Rig 10 moved
south from 10675N to add reserve ounces to the resource, whilst Rig 37 together
with Centamin's rigs stepped out north into the Ra zone to add resource ounces.
The mineralised system has now been proven to be continuous from section to
section as the drilling has progressed into the Ra zone, with the mineralisation
being consistent with the mineralisation logged in the Amun Zone
Geological logging of the diamond drill core indicates that the zones of
mineralisation are well defined within the Sukari porphyry. Mineralisation is
related to stockworks, brecciation, quartz veining and contact mineralisation,
these are traceable along the strike and dip of the Sukari porphyry.
Stockworks are broad zones defined by sericitic and chloritic alteration, the
porphyry is highly fractured and jointed, these are infilled with high ratios of
disseminated fine grained pyrite and arsenopyrite in the altered porphyry.
Zones of brecciation are well defined within the broader stockwork. The breccia
is characterised by fragments of porphyry supported by fine grained pyrite and
sulphide matrix. Quartz veins and zones of breccitaion are easily identified
and indicate an increase in the tenor of the gold mineralisation.
Stacked east dipping structures (breccia) normally contain the high grade with
medium to low grade mineralization occurring in the quartz and sulphide
stockwork in between these structures.
Contact mineralisation with the footwall is in close proximity to the porphyry
and found in association with highly foliated metavolcanics, these display a
high ratio of pyrite and quartz veinlets. Along the foot wall contact an
extremely high grade zone, the 'Hapi Zone', is present and continues to be
intersected
The extensiveness of the system is best demonstrated by SDDH 284 which
encountered the mineralised porphyry 9m from surface with an intersection of 1m
@ 75 g/t Au, and continued in mineralisation for over 400m down hole. Drill
hole data and assays are included in the tables below with some assays still to
be received.
Holes drilled and assayed to date show continuity along strike adding
significant ounces in areas previously undrilled. For Example:
SDDH 275, 100m @ 1.71 g/t incl. 41m @ 2.06 g/t is 25m along strike from
SDDH 278, 120m @ 1.63 g/t incl. 38m @ 2.27 g/t which is 50m along strike from
SDDH 282, 107m @ 2.42 g/t. incl. 40m @ 3.37 g/t.
The development program to move one of the Stanley rigs and Centamin's 3 rigs
north into the Ra zone and add resource ounces has been a resounding success,
with significant mineralisation encountered in every hole.
It must be stressed that the Amun and Ra zones are continuous and contained
within the Sukari outcrop, with the division between zones made purely for ease
of reference rather than being separate structures. As such Sukari has the
ability to be a multi million ounce single pit deposit, with the Ra zone yet to
be included in the resource calculation and the Gazelle and Pharaoh zones yet to
be tested by drilling.
Drilling is continuing and further results will be released at the time of the
resource upgrade which is planned for February 2003.
