Ann: Bryah Basin Exploration Update, page-23

Yes. Yarlarweelor is a jasperoid depsit hosted within volcaniclastics above a chlorite-sericite-pyrite alteration zone within the Narracoota/Ravelstone transitional sequence. Which is to say, one of the 'exhalative cherts' found basin wide in the 'Horseshe Lights Mine Sequence' AKA 'Corridor of Riches' AKA SFR's target horizon, etc etc. The drilling by BYH at Windalah looks, to me, exactly like the sequence at Yarlarweelor. So, something to keep your eye on. 

Auris, you'll remember, investigated copper anomalism at Fortnum even within the Starlight pit, and that led them south to Big Billy, Forrest, Wodger, etc. The gradient array IP that Auris is doing is likely to detect any of these so-called VMS footwall chlorite-sericite-pyrite alteration zones (conductive) and the jasperoidal cherts within them (resistive). Whether this works or not is to be seen, but it should do OK. 

The question will then be - does Auris drill the conductive zones under the assumption that there's an accumulation of sulphides leading to a copper ore body, or do they drill the resistive zones and hope to hit a Yarlarweelor / Windalah gold anomalous zone? To my mind, they should do both, as it's getting tough to justify drilling umpteen holes chasing barren pyrite (eg; BYH's deep hoes at Jupiter got scads of boring pyrite) whereas a decent jasperoid hosted gold deposit is a worthy target.
