White Cliff Minerals (ASX:WCN) has observed broad intervals of sulfide mineralization from regional drilling along the main fault zone during the reverse circulation programme at the Danvers copper project in Canada, according to a Tuesday Australian bourse filing.

One of the drill holes intercepted 65 meters of copper sulphides from 48 meters, while two other drill holes returned wide intersections of lower concentrations of copper sulfides interpreted to be near, but not intersecting the main lode, and will be followed up with further drilling in due course.

The company said diamond drilling is now active at the Hulk and Stark prospects of the project.
