Jul 13, 2022 (Therese Pettigrew) - The East Dyke is 19 m wide and >1200 m strike length. Prospecting in 2017 identified spodumene mineralization in the East Dyke pegmatite, with a mineralized zone containing up to 10% fine- to coarse-grained spodumene ranging in size from 0.5-6 cm and grading up to 2.56% Li2O. (Assessment report 20000016979). In 2001, Navigator Exploration Corp. conducted exploration to assess the tantalum potential of the East Dyke (Assessment report 32E04SW2004). In June 2001, seven grab samples were collected and analyzed for Nb and Ta, and the pegmatite was prospected. In August 2001, a channel was cut 16.6 m long from wall to wall across the western part of East Dyke and analyzed for Nb and Ta and multi-elements as 1 m samples. Feldspar and mica pairs from 4 channel samples were analyzed for multi-elements. Navigator concluded that the tantalum levels in the grab and channels samples were low and the trace element content of the feldspar and mica pairs were also unencouraging. The East Dyke is less evolved than the other Case pegmatite Dykes and thus likely has no potential for economic amounts of tantalum.
