| Location and accuracy | The Slate Creek lode occurrence is located at an elevation of about 3,100 ft approximately 4 miles southeast of the Myrtle Creek landing strip (sec. 12, T. 27 N., R. 11 W., of the Fairbanks Meridian). The location is accurate within a 1/2-mile radius. |
Geologic descriptionThe occurrence is described as blocks of talus as much as 30 cm in diameter of pink- and cream-colored silicates with manganese values as much as 22.23 percent (Fechner and others, 1993). Manganese oxide-stained chert with fine- to coarse-grained chalcopyrite was found nearby. The mineralized chert gave values of as much as 16.36 percent Mn. The manganese-mineralized rubble crops do not extend more than 30 m in any direction. The area is mapped by Brosgé and Reiser (1964) as within the chert unit of a Devonian(?) sequence of volcanic rocks and chert. | |
