Hi Folks! Well, I have lots of research links for anyone interested here. If not, click forward! If so, I apologize for the length. Some good research links are included:

This is brand new to the Geological Survey of Canada Website. It is all about the Slave craton geol., etc (worth reviewing):
"Kimberlite Indicator Minerals in Till, Central Slave Province, Northwest Territories"

If you haven't, def'ly see their "Mineral Exploration" page: sts.gsc.emr.ca

If you have time, go through this Diamond presentation, including d.mining history, formation, facts, figures, etc. w/ great photos:

eg., "China and the emerging East-- Fifty years of communism is coming to an end and bringing with it 1.2 billion new consumers. As in most areas of the economy, the diamond industry is growing in the East. De Beers has launched an intense advertising campaign to attract and educate new consumers."

A description of NWT diamond find/rush, as well as a table "SUMMARY OF KIMBERLITE PIPE BULK SAMPLE RESULTS NORTHWEST TERRITORIES", & more (good read):

"Near the surface, kimberlite bodies, often comprising multiple intrusive phases, take the form of small, carrot-shaped volcanic pipes or diatremes that are accompanied by associated dykes and sills (Figure 4). At the surface, the pipe may be expressed as a maar (crater) surrounded by a low accumulation of pyroclastic debris known as a tuff ring. Kimberlites tend to occur in clusters of 6 to 40 individuals, with each cluster occupying an area some 40 km in diameter... Almost all kimberlite pipes containing economic concentrations of diamonds are found on those portions of the cratons that are Archean (older than 2,500 m.y.) in age."

A more technical description of diamond exploration. Anyone serious about learning more tech. for their investment has got to check this out:
syd.dem.csiro.au
"Geochemical methods of diamond exploration rely on recognizing indicator minerals that formed in the earth's upper mantle, within the diamond stability field, and were entrained in rapidly rising volatile-rich magmas and emplaced in or on the crust (Fig. 1). Diamond is only stable at high pressure. Therefore, diamond exploration commonly targets prospects containing high pressure minerals, such as low-Ca, high-Cr ("G10") garnets and high-Cr chromites, similar to inclusions in diamonds."

"The AGS has released the results of a comprehensive, 3 year study into the potential for diamond-bearing deposits in Alberta. The results have been compiled into a 158-page report (Bulletin No. 63) that points out that Alberta may have moderate to high potential for diamondiferous diatremes and vent-related deposits..."

"Although the sample distribution in northern Alberta is irregular, three geographic trends, based on the number and quality of eclogitic and other indicator minerals, have been recognized in northern Alberta. These include: (a) a southwesterly trend from just north of the townsite of Peace River to the Birch Hills northeast of Grande Prairie, (b) a southerly trend from the lower Wabasca River to the Loon River, and (c) a southwesterly trend in the Marguerite River to Fort Mackay area...
The surficial geology and glacial stratigraphy of the Peace River region (NTS 84C/ w half) indicate the area was affected by one major ice advance.... In the lowlands, deglaciation caused the formation of glacial lakes which inundated the Peace River valley including the towns of Manning and Peace River. Glacial stratigraphy in the study area is recorded by one glacial till."
