D	SY161	170.2	173.2	OMS	Pyrite - dolomite - sphalerite rock. Carbonate replacement mineralisation of host silicified dolomite. Estimated 25% of dolomite host still present as an irregular mass.

D	SY162	59	68	OMS	Very vuggy and leached sulphide zone with pyrite, galena and sphalerite in that order of abundance. Mineralisation appears to be hosted in the siltstone, but host could also be a dolomite interbed. Interval from 62 - 68m not as massive and contains more bleached host rock.

Some darker carbonaceous fragments at 54m represent narrow siltstone interbeds. Lots of core loss nrar start of hole.	TAN										FE	2																					
D	SY163	62.1	93.1	SCI	Very carbonaceous until 80m - almost could be considered a black shale, at which point fine laminations become more visible.
