Kimberlite is just one of several rock types found at the earth's surface that sometimes contains diamonds. More than 40 kimberlites were initially mapped in the Colorado-Wyoming State Line district (1), this was followed by mapping of a small kimberlite blow in the Sheep Rock district (2), a major dike-blow complex in the Iron Mountain district (3), and the mapping of a major lamproite ...

In 1986, a 3175- tonne bulk sample was shipped to the Dankoe mill at Keremeos and yielded 109.44 kilograms of gold (Assessment Report 19437). In 1993, as a result of mining at the Heino-Money zone, a total of 5503 tonnes of mineralization with an estimated head grade of 24.4 grams per tonne gold was shipped to the Goldstream mill (MINFILE 082M 141) for processing.

The lamprophyre dyke intruded into the dolomitic marble, forming a serpentinized contact zone. The zone consists of olivine, serpentine, calcite, dolomite, biotite, spinel, and hematite. Minor F and Cl contents in the serpentine and biotite indicate the composition of the infiltrating H 2 O-CO 2 fluid.
