The Idaho-Maryland Mine Project is designed to minimize new land disturbance by using or reclaiming previously disturbed land. The placement of engineered fill, barren rock and dry sand tailings, derived from gold production, is designed to maximize usable land. Instead of “mine waste” the project creates over 50 acres of new flat buildable land. This land is vital for the local economy.
Brunswick Industrial Site
The Idaho-Maryland Mine Project will be constructed on the Brunswick Industrial Site.
This existing industrial site has been an employment center for Nevada County for 130 years and will be restored to productive use with minimal new disturbance.
- Mining at Brunswick from 1888-1956
- Main Vertical Shaft to 3400 feet below surface
- Healthy forest, housing, and orchards surrounded mine
- Commercial Sawmill from 1956-1991
- Closed when SPI purchased Bohemia for timber lands
- Numerous houses surrounded sawmill during operations
Centennial Industrial Site
The Centennial Industrial Site is the historic tailings storage location for the Idaho-Maryland Mine.
This site has been unusable for almost 70 years since the mine closed in 1956.
Rise will reclaim and restore this site to provide rare and valuable flat industrial land for the benefit of the local economy.
- Creation of 31 acres of industrial land with Engineered Fill
- Some historic mineralized material to be cleaned up under DTSC voluntary clean-up agreement prior to fill placement
