Description

This is a copper vein filled porphry slab from the Chino Mine in the Santa Rita District, Grant County, New Mexico, USA. This mine is a huge open pit operation. It was once the largest open pit mine in the world but it was recently surpassed. The mine is also famous for its outstanding mineral specimens which include the famous spinel crystals found by Stan Esbenshade. Stan also produces these slabs from largeĀ  boulders that he recovers from the mine. This slab contains several veins of native copper. The copper has a metallic luster which flashes like new penny as the light source changes. This slab has been coated with a thick coating of urethane resin. This piece measures 4 1/2 x 2 3/4 x 3/8 inches or 114 x 70 x 9 mm.
