Results from two drill holes have enabled Diadem Resources (ME) to confirm the presence of a lamproite dyke on its property in Leek Springs, Calif. The holes, in conjunction with stream sediment samples, indicate the dyke is more than 6,000 ft. long and 600 ft. wide; it appears to be one of a cluster of deposits.
Indicator minerals observed in the core and stream sediments suggest the lamproites are from a diamond-bearing source. Diadem believes that one or more of the dykes in the cluster could be the source of diamonds that were found below Leek Springs by miners during the California gold rush of 1849. Core from the drill holes is being analyzed for possible microdiamond content. Diadem plans to continue with its program in the spring.
