Hilltop Property, Northwest Territories
Overview: Exploration on the Hilltop property has included 14,280 line-kilometers of detailed airborne geophysics, 400-line-kilometers of ground geophysics and 2,375 till samples. Several high priority targets have been identified, focused within a significant, and as yet, unresolved kimberlite indicator train. Located within the central portion of the property, the mineral train measures 7 kilometres long by 1.5 kilometres wide. Numerous kimberlite fragments have been discovered within this train. Two diamond drill holes tested a structure at the head of this mineral train in 2003. No kimberlite was discovered. Exploration efforts on this property have focused on the "Hot Spot" indicator mineral train. This unresolved 7 x 1.5 kilometre KIM train lies at the centre of the claim group. Despite the discovery of kimberlite float and anomalous counts of chrome-rich pyrope (up to 15% Cr2O3) at several localities within the train, the source has yet to be identified. Diamondex crews conducted an exploration program on the Hilltop property that included till and geochemical sampling as well as geophysical target evaluations. Most of the 114 till samples collected came from within the Hot Spot train but several samples were also collected up-ice of this feature. The geochemical sampling campaign was undertaken in an effort to prospect for kimberlite within areas where previous till sampling efforts have not proved to be effective. In all, 1,647 separate samples were collected from two grids, which hosted 549 individual sample sites. Evaluations of 16 geophysical anomalies (ground truthing) were completed as well.
