Report: Midnight LC007358 The Midnight is located on private, patented ground. Additionally, there is a Midnight mill site located to the east of the Mike Horse mine road at Shoue Creek. Locations were found on an original map of patented claims located in the MBMG mineral property files. References describe this mine as several adits, last worked in 1926, partially caved in 1947 (Shea, 1947) hosted in diorite and argillite (Spokane shale). Minerals, again according to Shea, 1947, include galena, sphalerite, bornite and pyrite
