Hello Maintenance
Sorry but I just noticed your post of Nov 18 and apologize for not getting back to you before now.
I really have not been following the WSP thread very much. I just get too tired of all the bickering and sniping and don't have the energy to skip through all the nonsense.
I mentioned last week that I was going to attend the NWT Geoscience Forum and would report back if anyone was interested. Unfortunately, I tore up my knee the week previous, and attempted to avoid the lunch rush by leaving a bit early. As it turns out, I missed the WSP presentation Friday, which was apparently made just after I left.
I spoke to a few who did attend however, and from what they told me, it pretty much sounded like the same old same old. I asked if there had been any mention of age dating of the kimberlite dykes, and the attendees indicated that there had not been to their recollection.
The Jericho pipe talk by Canamera and Aber talk by Abby and Ira were interesting in that regard however. Harison (Canamera) confirmed that Jericho had been dated at 176 Ma and was definitely a lower diatreme. Most of the Aber/Dia Met pipes have been dated around 50Ma and Ira indicated that most of these appear to have been modestly erroded, no more than 150 - 200m. Mountain Province's 5034 (Kennedy Lake) is around 110Ma I believe, and is widely understood to be primarily hypabyssal in nature (primarily lower diatreme to root zone preservation). Tesla and the others nearby the 5034 have not had their ages published as of yet.
Every diamond consultant and company expert I spoke to prior to, and at the Forum, each confirmed that dykes are definitely indicative of root zones and/or hypabyssal structures. Suggesting that most if not all of these are either very old kimberlites or young but of course heavily erroded.
So, at the very least, there is evidence in the craton of multiple intrusive events seperated by as many as 120Ma within 100km of each other. No such absolute evidence exists as yet in the area of the WSP play, nor of kimberlites with such age spreads found close to one another, but that does not mean it does not exist.
Regardless, there is no reason to believe that it could not.
The dilema remains, if younger less erroded pipe(s) exist in and around Snap Lake, with such intense and focused exploration, why have they not yet been found?
I noticed Walt at the Aber presentation, and presume he also attended the WSP session. I am sure he can offer more information about it.
