Hey, dude, I'm a real fan of yours--your links have been much appreciated by more exploration- and mining-types than you can imagine. Merci Beaucoup, dude. Concerning your question:
>> Re. the line about the innovative geologic model, I'd like to know more about it! I assume it's now including seismics & EM's?- Do you know? <<
Yeah, but company confidentiality (and a "lil" thing called ethics <grin>) does not allow this geezer to reveal all. So here's a bit o' the sanitized mining geophysics for public consumption.
Seismics: As your posting of the APEX Geoscience (e.g., bottom of Page 3) report also states "...and re-interpretation of old and new seismic data are being (did you note the typo?) used with success in some places;". The "oil-patch" seismic data which Ashton presented last month in Toronto were very diagnostic for upgrading Ashton's magnetic anomalies to high priority drill targets. (In my never humble opinion, the juniors working in areas of thick till should review the brokered seismic data before drilling any boreholes! My clients do; hopefully, Montello did.)
EM: No electromagnetic (i.e., EM) geophysical data from the Alberta Kimberlite Play have been published (that I'm aware of), yet. Dighem had their helicopterborne 5-frequency coaxial-coplanar "bird" flying out of the Peace River airport in October. Rumor while I was in Peace River in late October was that "Ashton" was flying the bird over their kimberlites--unsubstantiated rumor from the bush was that the high-frequency coplanar response of specific kimberlites was "not subtle" (note that either no or gigantic would confirm the response "rumor" <grin>). [As you well know, thick till can make both EM and Mag interpretation very difficult for kimberlite exploration (also airborne EM usually costs three to five times more than Mag, therefore, I think neglible EM has been contracted for the Alberta play to date.)]
Thanx again and Best Regards,

P.S. Also note the cover page to Yorkton's "Diamonds in Alberta" 6-Feb report by Ettlinger and Leishman. Note that Ashton's K5 Complex occurs on the intersection of a NS and a SE magnetic gradient. I think the structural controls on Alberta's kimberlite intrusions are very important--the NS trends are more than just interesting. |
