This looks promising,... but,... I am reminded of what I read in the northern miner (geology 101)
The major diamond producing nations are South Africa, Botswana, Australia, Russia and Zaire. In Canada, production from the BHP Diamonds-Dia Met Minerals operation at Lac de Gras, N.W.T., will begin later this year. The vast majority of diamond production is from kimberlites, with only the Argyle deposits providing substantial production from lamproite sources. About 3% of kimberlite pipes, which can occur in clusters of up to 50, contain diamonds, and only 1% of those occurrences are economically exploitable.
Please don't hate me. My heart is with Brian but my head keeps getting in the way.
