The Spectrum mine is a patented 20 acre lode mining claim located on a deposit of calcium-rich plagioclase phenocrysts which is hosted in basalt flows. The mine produces gem quality plagioclase, some of which contains inclusions of copper parallel to the principal cleavage-plane, which causes an optical effect called schiller, often referred to as Oregon Sunstone.
The Spectrum property is currently owned and operated by High Desert Gems and Minerals which conducts intermittent surface mining operations. The site is also the location for a commercial fee-for-dig screening operation and camping area which are open to the public by reservation.
