Problem:
 In May of 2002, PHC Reclamation, Inc. (PHC-REC) began site investigation, site hazard assessment and on-site fieldwork for AML Project 17F-9, the Copper Mountain Mines Project. Mineral exploration and extraction of gold, copper, silver, tungsten, feldspar, beryl and low-grade uranium resources was conducted throughout the Copper Mountain region from the early 1880's to the mid 1970's. Due to the diverse types of minerals mined or prospected, the mining techniques and the extent of mining disturbance varied greatly. To date, minor exploration and a few active mine claims on lands administered by the Bureau of Land Management (BLM) exist.

Objective:
 The purpose of the project is to evaluate and eliminate the public safety hazards associated with abandoned underground and surface mine sites located in the historic Copper Mountain Mining District. Work performed included site investigation and evaluation, consents and clearances, eligibility research, mine permit and exploration notice research, mineral claim research, previous reclamation assessment, surveying and mapping, hazard documentation, conceptual designs and costing.

PHC Solutions: 
 The project area encompassed 52 Sections across three (3) Township and Ranges. Over 505 mine features were inventoried. Approximately 120 mine features represent an immediate hazard or potential injury concern to the public and wildlife. PHC-REC field personnel identified the existing and potential safety and environmental hazards pertaining to open or partially collapsed portals, prospect pits, exploration trenches, adit workings, subsidence features and highwalls, unstable spoil piles and dilapidated structures.
 A database was established with GIS interface to house all investigation and inventory work performed.

Results:
 Reclamation designs were developed to mitigate the public hazards. The designs were influenced by many factors including the type of hazard, access, cultural resource and Threatened and Endangered Species concerns, and special interests from the BLM, Fremont County, private surface and mineral owners, and claimants.
|
 In addition, acidic mine drainage, mine spoils in ephemeral and intermittent drainage's, impacted wetlands, soil deposition and gully erosion problems were identified at numerous mine site areas. These conditions will be addressed per federal and state environmental cleanup and mitigation standards with design concepts involving channel re-alignments, spoil encapsulation, placement of erosion and sediment control features.
