The Apex mine of the Money Creek Mining District lies in a glacial cirque at an elevation of 3800 feet.
The Apex deposit was discovered during 1892 by John Maloney, an engineer for the Great Northern Railway. It was one of the first discoveries in the district.
The mine has a checkered history of production owing to periods of changing ownership and its isolated location in mountainous country. Accumulations of 6 to 9 feet of winter snow and demanding trail access to the mine, contouring around steep cliffs, mandated construction of an aerial tramway to facilitate production.
Adit #5 is a previously unexplored adit due to being sealed by collapse for 90 years. Adit #5 was located at an elevation of 3000 feet and was 1200 feet in total workings. The #5 should be considered extremely unstable and dangerous to enter.
In 1936, W. J. Priestly, manager of the property from 1915 to 1943, conducted a comprehensive sampling of the vein material exposed in adits 2, 3, and 4. Ninety-one samples averaged 1.2 ounces of gold per ton and 7 ounces of silver per ton.
