The two claim groups, comprising 33 units, are accessible via a winter road to Norman Wells, N.W.T.
Stream-sediment sampling by De Beers Canada in the 1970s and ’80s identified a distinct kimberlitic indicator mineral anomaly in the area of Blackwater Lake. The lack of abrasion on the minerals suggested limited transport.
In the early 1980s, soil sampling and magnetic surveying over 345 line-km on Patrician’s new claims turned up several kimberlitic indicator mineral anomalies. The best indicator count from a single sample was 145 garnets, 117 ilmenites and seven chrome diopsides. Overall, about 1,800 glacial sediment samples were collected from depths of no more than half a metre.
Limited drilling in the area has failed to cut kimberlite.
Patrician believes the mineral assemblage at Blackwater is distinct from that at Lac de Gras, some 300 km northeast of Yellowknife, and that this indicates a separate, and likely local, source.
Analysis of till samples indicates a clustering of anomalous garnet and ilmenite grains in two main areas on the northern half of the property.
The company plans to change its name to Patrician Diamonds.
