Fuchsitic veined zone between 167.5 - 168.5, irregularly shaped to 3mm width. Sphalerite, where present is very coarse-grained and brown in colour.

D	SCD001	183.5	199.3	SSI	Weakly siderite veined mostly laminated siltstone with a brecciated texture in places. Lithology grades into a sandstone texturally, producing an interbedded nature to the appearance of the interval. Narrow 1-2cm sphalerite-galena vein at 191.9m.

D	SCD001	225.1	251.5	OBX	Black shale breccia, cement changing from quartz to siderite along interval, brecciation very clearly defined and present mostly as angular clasts (clast-supported) with a milky coloured quartz cement. Significant siderite veining between 243.8 and end of interval. Very coarse-grained 30mm width galena veins at 249.6m and 250.45m.	BLK	WHI	QTZ	4									PY	1	VI	GAL	2	VI				BRX			VAN								
D	SCD001	251.5	293.1	SCI	Carbonaceous siltstone breccia with quartz veining and minor siderite veins. Brecciation intensity generally increasing towards the bottom of the interval. Small graphitic shears plentiful,  particularly in the more carbonaceous sections. 	BLK	WHI									FRS		QTZ	8	FS	SID	0.5	VI				BRX			SHD								
D	SCD001	293.1	303.8	VCC	Strange greenish-grey coloured lithology, difficult to identify,  possibly altered volcaniclastic sandstone. Green mineral likely chlorite, small 1mm specks of a dark grey mineral, probably graphite. Gradational contact over 10-15cm to a breccia at upper and lower contacts of interval.

D	SCD001	303.8	332.6	SCI	Carbonaceous siltstone approaching cataclasite with occasional weakly hornfelsed sections exhibiting varying degrees of brecciation. Hornfelsed bands appear bleached and tan to khaki in colouration. Some irregularly shaped siderite-quartz veins present from 322m to end of interval with subordinate sphalerite and galena. Trace green fuchsite present as narrow veins.	BLK	WHI	SID	3									SPH	1	VI	GAL	0.1	VI	PY	2	VI	BRX			BAN

D	SCD002	2.2	93.2	SSI	Volcaniclastic derived siltstone, frequently finely laminated at 30-40 degrees to LCA. NQ from 62.8m. Base of total oxidation 4.6m, BPO 30.8m. Interval 0-13m characterised by abundant Fe and Mn oxidised in fractures. Facing sedimentary structures indicate beds are upright. Fracturing ends abruptly at 30.8m. 	GRY	TAN	PY	1	0.5	30					FE	3										FRA			GDB			LAM					
D	SCD002	93.2	156.9	SCG	Conglomerate and siltstone, interbedded with thickest interbed between 124-132m. Sub-rounded clasts, clast-supported, occasional bright green fuchsite clasts, as well as presence as a selvage on white, coarse-grained quartz veins. Variegated chert and shale clasts generally less than 10mm in an arenaceous matrix. Frequent interbeds of fine-grained sandstone and siltstone. 	GRY	CRM									FRS																						
D	SCD002	156.9	202.5	FZ	Brecciated fault zone composed of angular clasts of carbonaceous siltstone and fine grained sandstone with a white to grey quartz veined sometimes colliform cement. The last 5m of the interval is far more carbonaceous and verging on a black shale. This more graphitic zone has taken up more of the strain and movement with a sheared texture in places. Minor irregularly shaped  3mm quartz veins with clots of sphalerite present. A coarse-grained quartz vein with angular wall rock inclusions from 168-170m appears to be almost parallel to the LCA.

D	SCD002	202.5	253.5	MMF	Weakly hornfelsed siltstone characterised by weak pervasive siderite alteration as well as occasional siderite breccia veins with subordinate included coarse-grained galena and sphalerite blebs. The sediments appear to have a very weakly developed hornfelsed texture, giving the sediments a light-tan bleached appearance and brittle micro-fractures.

D	SCD002	253.5	335.5	BH	Quartz and calcite veined carbonaceous siltstone breccia with occasional coarser grained interbeds of fine-grained sandstone, and occasional finer-grained shaley or muddy material. The unit is mixed texturally, but has a pronounced brecciated appearance particularly from 267m onwards. The more carbonaceous, graphitic bands appear to be more sheared and preferentially take up more of the strain. Similar to previous interval but without hornfelsing texture. 2-3mm siderite breccia veins are rarer and where present only contain trace galena and sphalerite. Interesting siderite veins to 10mm width with accessory pyrite blebs occur from 330-331.3m oriented parallel to the LCA. 	GRY	BLK	QTZ	3	4	45							PY	0.1	BL							BRX			VAN	45	4						
D	SCD002	335.5	419.4	SCI	EOH. Carbonaceous siltstone, still well brecciated,  but far less veining present. Interval is generally finer-grained and has less shaley interbeds. Quite graphitic overall, the interval has bands where brecciation is absent and bedding can be seen (382.4m) at 40 degrees to the LCA..	GRY	BLK	QTZ	1	1																	BRX		1
