The Plinco Mine was located in the Last Chance area of northeastern Plumas County. Doyle in Lassen County was in part beneficiary of the mining operations due to the access with the Western Pacific Railroad. From the mine to Doyle was approximately thirteen miles.
The initial mine was discovered in 1905 by Joseph Novak of Utah and Orlando McNabb of nearby Milford, an avid prospector. Attempts to develop the mine languished. In the fall of 1915, J.F. Cutler, a Midwest capitalist began an ambitious project to develop the Novak Mine. On November 2, 1915 Articles of Incorporation for Plinco Copper Mine were filed in the State of Nebraska. Cutler stated at that time he had ten men working on shafts and buildings investing some $16,000 in the venture. There does not appear to be much documentation about the Plinco mine. In late August 1919 a massive forest fire, to be named the Ferris Fire ravaged the Last Chance country and destroyed the Plinco Mine buildings. The operation then ceased to exist.
