Depends on age. Pipes vary from 1 billion to 16 million years in Arctic, just like Kimberly South Africa. (Here in this shield territory of SA, billion year old pipes such as the Premier may still be large.) If the pipe is late late, late it can be into limestone and not eroded at all. Prior to that it is up for grabs. Some pipes in Northern Ontario subcrop under paleozoic cover. Some are into Blake River volcanics. If they are Cretaceous, they have seen all the erosion since then that exposed and peneplaned the volcanics. So I would not buy that volcanic intruded pipes are less eroded.

The Somerset Island pipes were fairly large, and very widely diamondiferous (Mitchell). I don't know about crater facies but certainly diatreme. The ones that intruded the paleo in Ontario were diatreme by my core inspection. KL pipes varied but were mostly diatreme. (50% diamondiferous, and high carbonate. No good chemistry work done yet, but good looking and plentiful pyrope) Debeers said in their log that the Victor was hypabyssal, but we have not seen that. Inspection of Mountain Province tells me it was crater and diatreme. Snap lake was high level diatreme despite its limited geometry. We are seeing many crated facies pipes in the territories. Wawa pipes that I saw were diatreme texture. (Protected from erosion even in that environment by limited deep erosion of Algoman orogeny.) So I would say that it is a combination of age, and cover intruded into.
Bottom line? I would bet you could see anyhing anywhere. In the paleo, you could see deep erosion of older pipes pre paleo, and also young pipes too. But with extreme age differences, you would expect different environment, level and character. Since paleo cover areas are quiet, you could say also that late pre paleo pipes, may be not that much eroded as they formed in low basin structures.

Mr. David Stone reports
10.23 CARAT DIAMOND RECOVERED FROM FORT A LA CORNE KIMBERLITE 140/141
Kensington has been notified of the recovery of a 10.23-carat diamond from a recent drilling and sampling program conducted by the Fort a la Corne joint venture. The operator, De Beers Canada Exploration Inc., today notified the company of partial preliminary results arising from final diamond recovery activities at its secure facility located in Johannesburg, South Africa. Minibulk samples were acquired from the drilling phase of the 2002 advanced exploration/evaluation program on kimberlite 140/141, which is one of several high-priority bodies identified in the Fort a la Corne kimberlite field, located 65 kilometres east of Prince Albert, Sask.
The large diamond was described as a dodecahedral aggregate stone with two dimensions measuring 14 millimetres by 10.5 millimetres, but no information is available at this time concerning value of the stone or the potential effect on grade forecasts and average values for kimberlite 140/141. The company acknowledges that the disclosure in this news release does not meet the requirements of sections 2.2, 3.2 and 3.3 of National Instrument 43-101 Standards of Disclosure for Mineral Projects, as a result of the preliminary stage of the diamond recovery reporting. Final diamond recovery procedures are continuing at the newly renovated De Beers facility and the company will release full results, in accordance with the requirements of National Instrument 43-101, as they are received and evaluated. The company anticipates release of this information by midyear of 2003.
WARNING: The company relies upon litigation protection for "forward-looking" statements.
