A Pb-Zn occurrence/mine located 0.7 km (0.4 mile) WSW of Durango and about 5 miles NW of Dubuque. There are three main crevices containing ore.
Deposit: Deposit mined by indians before 1790's, then by by julien dubuque 1788-1810, then by fox and sac indians 1810-1820, and afterwards by miners from the eastern united states. Galena mined first; zinc production started about 1860. Cadastral location: NE 1/4 sec. 1, t. 89 n., r. 1 e. ; info.src : cobb
Geology: Ores found in a 5 mile long e-trending mineralized fracture zone; zinc occurs in secondary minerals formed from sphalerite.
Rock formation(s): Galena Dolomite
