I'm no geologist but a few months back we were all talking about Lapilla as a possible marker. Now we have another possible volcanic tuff marker. Things coming together with the more data points. I've cut and pasted the part of the Novo release I found most interesting


Quote from Novo Comet Wells release of March 20, 2018 on Comet Wells

Trenching and Bulk Sampling

"At the Powerline showing, a new gold-bearing conglomerate horizon has been exposed approximately 20 m up section from the basal bouldery unit (Figure 5). The thickness of this horizon has yet to be determined, but several gold nuggets encased in rock matrix have been recovered as the weathered portion of this horizon has been stripped away in preparation for sampling (Figure 6).
This new gold-bearing conglomerate rests on top of a thin, but distinct marker horizon of possible volcanic origin containing large lapilli, or rock fragments, in a dark ashy matrix. Novo geologists have been able to trace this marker unit along strike to the east from the Powerline showing and have also identified it in several scout diamond drill holes (Figure 7)."
