Gemstone Mining
After  your tour you may want to try your luck mining for real gemstones or genuine fossils . The photos show what can be found in a single bag of mining rough.
Just purchase a bag of mining rough from the gift shop and take it to the sluice outside.  Pour your rough into the screened trays provided and watch for gemstones or fossils appear before your eyes.

  Use the identification board to see what you’ve found, or ask at the counter and we’ll be happy to help with some of the trickier ones.
