Gerle, Monopros come up short at Doyle Lake

A 6-hole drilling program at the Doyle Lake diamond project in the Northwest Territories encountered no kimberlite.

Gerle Gold (GGL-V) holds a 40% interest in the project and is the operator.

Monopros, the exploration arm of De Beers Consolidated Mines (DBRS-Q), recently earned a 60% interest in the venture.

The program tested six targets on the LA 1-25 claims for a total of 1,223 metres. Earlier this year, a 20-hole program tested a series of geophysical targets on the claim block. No kimberlite was found.

Last year, drilling traced a narrow diamondiferous kimberlite sill over a strike length of 1.3 km, with intersections ranging from 0.2 to 5.7 metres in thickness. A composite 125.2-kg sample from four holes yielded 67 microdiamonds.

Gerle says Doyle Lake is proving to be an extremely difficult property, with a complex glacial history and unusual geographic features. “The excellent mineral trains and diamondiferous kimberlite sill tell us that kimberlites are in the area,” states a company release.

The northern boundary of the Doyle Lake claims lies just 200 metres south of the Hearne kimberlite pipe, recently discovered on Mountain Province Mining’s (MPV-V) AK property.
