A well-defined, contiguous zone of breccias (West Breccia Zone and Paramount
Zone) extends along the west margin of the Main Zone and to the north for a total
length of at least 2.1 km. Geophysical mapping to the south of the Main Zone
shows quite clearly that the breccia extends at least another 1.1 km to the south,
for a total of at least 3.2 km. The breccia most likely extends even further to the
south, but available data do not allow additional projections. To the north, drilling
and currently available geophysical mapping do not support extending the breccia
beyond the current limits of mapping (6361300N), although the breccia may be
offset in this area toward the northwest along a steep northwest-trending fault
