FALC kimberlites

The geological literature on Fort a la Corne has compared the site to Ndugr Mayi in Zaire. From 1930 to 1990, the mine at Ndugr Mayi produced 1/3 of the world diamond production. In 1996, in spite of the military conflicts in the area and the dear need for upgrading, it produced 6,5-million carats valued at $80-million. Productive kimberlites are not limited to the shapes found in the NWT.

The kimberlites at Fort a la Corne are best described as champagne glasses (coupe) with a narrow stem. They are mostly extrusive as the kimberlite has come up and settled over the sedimentary surface. Over time, the site has been recovered and protected by other sediments.

Sills, on the other hand are by definition intrusive, they fill in internal cavities. They are only very minor occurrences at Fort a la Corne.

Because of the shape of the kimberlites and of lateral zonal variations, the best mining option is still cheap open pit mining as described by the 1995 scoping study done by Fluor Daniel Wright Ltd.

The water table level is below the kimberlites and has never been a source of concern.
