there is a mixture of the sulphuret and carbonate. Besides
these, which are not considered important, there is a large
fissure, in places fourteen feet wide that has been traced
about a quarter of a mile. It is on the old Ansley tract,
and extends in a westerly direction towards Mineral Point.
For about the depth of fifteen feet the fissure was found to
be filled with an iron ochreaus substance named "gosson", and
lumps [lumps] of sulphuret and carbonate of copper mixed in it.
Below this depth is clay with a little ore scattered through it. The
lumps above were of all sizes, up to two hundred pounds
weight. No shafts were ever sunk to prove this fissure at
greater depth; but there is every reason to suppose that it
will be found productive in other parts, besides the atrip near the
surface. The little rock veins prove that the ore belongs
to the formation as much as the lead ores, and in whatever
way it may have been brought up from below it is likely to
to have formed other deposites in the fissure worth looking
after.
