Jun 29, 2011 (A Wilson) - On the dump, a few crushed, brownish-red zircon crystals were found in fragments of a fine-grained pink syenite. Some very large crystals were reportedly collected from this site. Some of the zircons have good hyacinth colour and parts of the crystals are sometimes suitable for gem cutting.
