9.2.1 Bull Hill
The Bull Hill deposit consists of an REE-mineralized carbonatite dike swarm and
associated enveloping stockwork zones located within and along the western margin
of the Bull Hill diatreme. Near-surface iron oxide-manganese oxide-rare earth (FMR)
and oxide-carbonate (OxCa) dikes and veins are interpreted to be intensely (FMR)
and moderately to weakly (OxCa) oxidized and leached equivalents of the carbonatite
dikes at depth. The dike swarm was discovered by Hecla Mining Company and
described in an unpublished Hecla report (Wineteer, 1991). Rare Element conducted
