Excerpt from the Ashton presentation:
----
"The Buffalo Hills Kimberlite Province, North-central Alberta, Canada"

...To date, 15 kimberlites have been discovered in the province, with inferred sizes ranging from <1 to ~45 ha. Some pipes are covered by variable thicknesses of glacial overburden up to 90 m deep. Several kimberlites outcrop, including the spectacular example of kimberlite K5 that forms a hill some 60 m high. Deep seismic profiles suggest that many kimberlites in the province exhibit distinct pipe-like morphologies, with initial pipe flaring apparently beginning at the boundary between Precambrian and Phanerozoic sequences. U-Pb dating of perovskite suggests that the Buffalo Hills kimberlites were emplaced between 86 (+ or -) 3 and 88 (+ or -) 5Ma.

Initial petrological studies of the Buffalo Hills kimberlites indicate that all material recovered to date is crater facies. A diatreme -facies component has not as yet been identified in drill core from depths of up to 200 m...
