Gem River growing

Sapphire reserves on the Lower Dry Cottonwood Creek property in Montana have increased by 21%, reports Michigan-based Gem River (GR-A).

Proven and probable reserves in the Upper Meadow portion of the property, where mining has resumed, are now estimated at 3.8 million carats.

The property, says Gem River, contains two other meadows that host sapphire grades equivalent to those found at Upper Meadow. This year, Gem River plans to explore these meadows while continuing to increase reserves at Upper Meadow.
