Here is the log for the last 70ish meters of the Rio Tinto hole at Oval. (Found on wamex)

	Hole ID	Meters From	Meters To	Dark/Light	Colour 1	Colour 2	Texture 1	Lithology
1	OVN001	164.1	164.5		GREY	GREEN	EQUIGRANULAR	**BRO
2	OVN001	164.5	206.8		GREY	GREEN	INTRUSIVE	**BRO
3	OVN001	206.8	214.4	DARK	GREY		BEDDED	SANDSTONE
4	OVN001	214.4	215.9		BLACK		BEDDED	BLACK SHALE
5	OVN001	215.9	218.2	DARK	GREY		COARSE	SANDSTONE
6	OVN001	218.2	220.5	DARK	GREY		BEDDED	SANDSTONE
7	OVN001	220.5	224.4		BLACK		BEDDED	BLACK SHALE
8	OVN001	224.4	232	DARK	GREEN	GREY	MONOMICTIC	**BRO

Interestingly enough, the hole actually ended with 8 meters in a **broic unit and not black shale. I guess they assumed that the two small intercepts of black shale were enough to be responsible for the conductivity anomaly.
By all means the interbedded sequence of Shale/**bro/Sandstone may very well continue at depth and be the reason for the anomaly.
Needle in a haystack but still a very exciting prospect in my opinion.

For me, I believe the three conductors they identified at their Fairbairn prospect are of more significance and potential.
