The mesmerizing flash of diamonds and their almost magical effect on women have been known for many years. But what can they do to junior mining companies?
Consider then, the drilling of a 3,000-ft large bore diamond drill hole from the top of a glacier. That’s what Dia Met Minerals is doing on its large property 50 miles north of Golden, B.C.
Consultant Edward Schiller says that the hole is past the 200-ft mark, well on its way down the middle of a large kimberlite pipe on Dia Met’s Jack property. Kimberlite, an ultramafic rock formed deep within the earth’s crust, gets its name from Kimberly, the famed diamond mining centre in South Africa where such rocks are found.
Based on geological mapping and heavy mineral analysis of stream sediments in the area, the company has identified a 10-sq km pipe. Bulk sampling of the brecciated, disrupted surface portion of the Jack pipe yielded not only indicator minerals such as pyrope garnet, ilmenite and chromite, but a micro diamond as well.
Although not ore grade, the micro diamond was of excellent quality, according to a technical report. Ore grades in diamond deposits average more than 0.25 carats per ton, or one part diamond per 20 million parts of waste.
The drilling is designed to test deep portions of the pipe, in order to learn more about its geology, the company says.
