Ferruginous iron-stained orange-brown coloured fractured structural zone from 11-13.5m and  35-47m. Base of total oxidation at approximately 15m. Base of partial oxidation approximately 48m. Minor disseminated medium to coarse-grained pyrite euhedra present within 11-13.5m structural zone, partially oxidised particularly within fractures. Cased-off to NQ at 152.9m. An 8m wide weakly-developed structural zone is present  from 83.25-91m characterised by fracturing and quartz-calcite veining providing a local focus for increased weathering. Signs of hornfelsing of the sediments increasing down the interval, with tan coloured and indurated brittle-fractured zones present in places.	GRY										FO		PY	0.1	DI							GDB			FRA								
D	SY800	158	417.6	MMF	Greenish yellow to grey weakly hornfelsed sediments with fine whispy 2-3mm calcite veinlets common, wider calcite veins often having an Fe-rich ankerite selvage. Frequent brittle micro-fractures visible, sometimes with movement of a few mm visible. Upper contact of interval very gradational over several metres. 10cm calcite veins containing a few percent coarse-grained galena and sphalerite blebs centred on 159m and 167.25m. Interval has occasional greenish coloured bands containing small 1mm clots of chlorite.	GRN	GRY	CCT	3	3						FRS		CHT	0.2	BL	GAL	0.1	VI	SPH	0.1	VI	LAM			BAN			FRA		3

First evidence down hole that the Balstrup Fault zone is close. Interval from 440m onwards more veined and appears more bleached in appearance due to intense calcite veining, some of the texture best described as breccia. Occasional very irregularly shaped thin whispy pyrite veinlets, largest of which occirs at 421.9 - 422.2m.	GRY		PY	2	3						FRS											VAN		3	BRX								
D	SY800	457.7	471.5	SSI	Pyrrhotitic brittle fracture stockwork zone. First clear occurrence of siltstone cataclasite texture at 460m, however some angular clast-supported breccia bands present a little earlier.This interval almost definitely represents a structural splay off the main Balstrup Fault zone. Narrow 20cm cataclasite/melange zones also present at 466.5m and 471.4m. 10-15cm band of galena and sphalerite-rich brittle fracture zone veining at 4615m, occasional blebs of sphalerite and galena within more pyrrhotite and pyrite material as described above.

D	SY800	471.5	503.3	SSI	Hornfelsed and silicified indurated siltstone. From 494.6m to 498m, a siltstone matrix-supported breccia band with vuggy Fe-rich carbonate cement/matrix occurs. The last metre of the interval contains abundant vuggy calcite breccia veins, which fractured readily during the drilling process. Occasional 2-3mm width fine sinewy pyrite-pyrrhotite-sphalerite veins. Balstrup Fault could be defined from 494-506.5m not including the brittle hanging wall zone.

D	SY800	506.4	568.1	SDL	Weakly skarnified and calc-silicate altered recrystallised dolomite. From start of interval to 528m, corresponding to the immediate footwall, the dolomite has significant magnetite and pyrrhotite with accessory pyrite present as strange almost spinifex-textured accumulations. The dolomite becomes more massive after this depth. Green calc-silicate minerals possibly epidote-actinolite occur in amorphous masses in close association with pyrrhotite and magnetite in this interval.

The upper contact, tray 135 photographed, supports the lithology being altered carbonaceous siltstone rather than dolomitic. Interval contains some significant pyrite-sphalerite-pyrrhotite-galena veins: 595 - 596.45m (semi-massive), 601.6 - 603m, 625.5 - 626.8m and a very talc-rich vein 630.65 - 631.1m with ony 15% sulphides.
