“Pyroclastics, specifically lapilli pyroclastics, occur in and near the Ashton pipes 125km to the east of the Chinchaga area;”
This statement sent me back to review the Ashton K14 results. you can find them at Ashton Canada's ‘news' location:
ashton.ca
Some quotes:
“The fourth new pipe, K-14B, has been detected by test pitting on a satellite magnetic anomaly 250 metres north of pipe K-14, which was found last winter. Additionally, test pits immediately north of the K-14 discovery hole have found kimberlite under relatively shallow overburden cover. Earlier analyses of a sample of 204 kilograms from the one hole on K-14 returned 190 microdiamonds and 12 macrodiamonds.”
Keywords "satellite magnetic anomaly".
Jesse, do you think this is what Richard was referring to? Is it your belief that K14B was in fact a crater facies? In hindsight, do you think that Ashton achieved a better diamond count from the apparent facies than from drilling the main K14 kimberlite? A lay person like myself has a difficult time sorting out the jargon - diatreme facies, pyroclastic facies, lapilli pyroclastics - YIKES.
Here is another Ashton quote:

Ashton Discovers Kimberlitic Pipes in
Alberta
John S. Auston, President & CEO of Ashton Mining of Canada Inc. is pleased to announce that the first two holes in a program of drilling in north-central Alberta have intersected kimberlitic rocks.
These drill holes on two separate geophysical anomalies are the first in an initial program designed to test 10 anomalies, all of which display the characteristics of kimberlite-style volcanism.
After penetrating 34 metres (113 feet) of glacial sediments the first vertical diamond drill hole on anomaly 7B passed into olivine-dominated fragmental and tuffaceous material displaying possible crater and diatreme facies textures. The drill hole remained in this volcanic-textured material until termination at 154 metres (505 feet)."
The question is, are we talking diatreme facies in Marums case; does the Ashton information confirm an association with the Marum find and so what? If Marum is drilling the facies, can the kimberlite pipe be far away?
Out of my depth, but working on it.
