A Au-Cu occurrence/prospect with underground workings. A group of 19 unpatented Cu claims with surface and underground workings located in the S½ sec. 5, T.14N., R.9W. (Bagdad 15 minute topo map), along the headwaters of Alum Creek. Located originally by Fred Gibbs in 1922 and in 1945 held by Alec Lucy and Frank Morton. The breccia pipe at the hedwaters is a little more than ½ mile slightly west of north of the Copper King Mine. Claims extend into the W½SW¼SW¼ of sec. 22. Claims also in secs. 6, 8, 9.

Area structures include foliation in metavolcanic rocks that trends N10E to N40E.
Workings include several prospect pits. A 170 foot long adit is driven into the breccia pipe near the headwaters of Alum Creek.
