In answer to some of your questions. Two of GMD's staff geologists have been let go. The company is just not as busy as it was.

The new guys are very real people, with very realistic goals. Their backgrounds have been presented in the information circulars and news releases. They have my full support.

A story about no work being completed on the Royce Group??? Haven't you seen the news releases about the airborne geophysical survey? About the new till sample results? About the acquisition of an additional 165,000 acres? About the follow-up program? GMD is investing more money on its diamond property than almost any other company in the NWT.

Primary diamond deposits are largely constrained to kimberlitic host rocks that intrude Archean Terrains. The older (deeper?) the stable crustal domain, the better chance the kimberlite acquires xenoliths from the diamond-stability field (>150 km deep). Exploration can focus on finding favourable terrains, and then looking for indications of kimberlite intrusions. The Royce Group covers a portion of the Archean Slave Craton (favourable domain) that both siesmic tomography and magnetotelluric studies show has a deep crustal keel penetrating >250 km (very good for hosting diamond-bearing kimberlite). Samples of tills contain G10 pyropes, kimberlitic chrome diopside, and ilmenite, plus some kimberlite fragments (very positive indicator of diamond-bearing kimberlite). Some of these indicators are constrained to the property (another plus).

In summary, GMD is in good hunting ground for diamond deposits, is known to host glacial dispersion trains of containing kimberlite fragments, and kimberlite indicator minerals that have (most-likely) come from a diamond-bearing kimberlite.
