We spend all day underground and enjoyed
the cool temperature. And no flies! We found
some opal chips, fossils and potch. Potch
are opals without colour. It is
rather dangerous, sometimes the mines colaps
and most fatalities happened in this claim
area. The plan for the digging now was
a further dig to the estimated position of
the opals. Another 2 days digging was
probably required to arrive at the position
where the opal pockets might be. It was good
visible that we did cut now through an area
where a hot spot has been. This is required
to give the opals colour, but too much heat
melts them down. This was good visible here.
Here we are checking carefully the wall,
instructed by Denise. We find many
"angelstone" who are associated with opals.
