Commodity type:	metallic
Major mineral:	Mercury
Operation type:	Unknown
Production size:	No production occurred
Development status:	Occurrence
ore:	Cinnabar
ore_ctrl:	Cinnabar Occurs In Fractures And Breccia Along Fault Zones In Sandstone, Shale, And Siltstone Of The Puget Group. Mafic Rocks Intruded The Sediments, And All Were Subjected To Folding And Faulting Prior To Mineralization (Mackin, 1944, P. 8). The Shear Zone That Localizes Mineralization At The Barnum-Mcdonnell Deposit Has A Maximum Thickness Of 10 Ft. The Best Ore Is In Tuffaceous Sandstone (Huntting, 1956, P. 256).

hrock_type:	Shale,Siltstone,Sandstone
tectonic:	Deltaic Deposits Of The Eocene Puget Sound Group Were Folded And Faulted During The Tertiary (Gard, 1968, P. 27-29). Mineralization Probably Took Place During Or Shortly After Deformation.
