The underground development is focusing on enlargement of the main Sonneman level to 3.7 m by 3.7 m to accommodate future production. Mining in the drift has advanced 412 m from the portal, and the first significant historic ore zone, the Laxey zone, was encountered in May at about the 275 m mark. Planned underground drilling will commence once the Sonneman has been developed another 183 m toward the DMEA zone, estimated for mid-September. The initial underground detailed drilling will target the down dip extension of this zone.Avalon Rare Metals has provided a progress update on its Nechalacho rare earth elements project, Thor Lake, Northwest Territories, Canada.
