Malachite

Geufron mine at Llanidloes in Powys, Wales, lies slightly south-east of the Snowdonia National Park and worked part of the Van lode.  The Malachite forms a hillocky thick crust of small mounds and ribbons with a velvety texture of predominantly light peppermint-green to occasional mid-leaf green.  The Malachite contrasts nicely against the slatey dark grey matrix with a rusty ochre-brown limonitic crust.  An impressive specimen from a seldom seen Welsh location, collected in May 1974.
