![]() Besides the work conducted by TIR at Lake Charlotte, grates to provide access for bats have also been put in place at Glenelg and Londonderry. In the past 11 years TIR has backfilled more than 200 AMOs, capped four mine openings at Caribou Mines and New Ross, and assisted NR&R staff in the placement of a grate to protect a bat habitat at Lake Charlotte. TIR plays a major role in the AMO Remediation Program, both in carrying out work with its own crews, and in tendering and managing contracted work. Methods for remediating AMOs include backfilling, fencing and placement of concrete caps over the mine opening. The AMO Remediation Program began in 2001, and since that time approximately 650 AMOs on Crown land have been remediated. Most of the AMO’s in the province (including those on private land) have been assigned a hazard rating, ranging from Type I (inescapable) to Type IV (no significant hazard). AMO hazards range from extremely dangerous to no significant hazard. These mine openings are spread across approximately 140 mining areas and each site may host anywhere from a single AMO up to 250 mine openings. There are approximately 2,400 documented AMO’s on Crown land in the province. Other factors are also considered, such as newly discovered hazardous openings or fill settlement in previously remediated, high-priority openings. A listing of AMO areas on Crown land has been prioritized and the work plan for each year is determined primarily based on the priority listing. The AMO Remediation Program is a long-term project, and approximately $50,000 worth of work is completed each year. Approximately 900 abandoned mine openings have been remediated through the program over the last 18 years. It is overseen by the Executive Directors of the two Branches and the Land Services Branch of Natural Resources and Renewables. The program is managed jointly by the Regional Services Branch of Natural Resources and Renewables and the Geoscience and Mines Branch at NSDEM. The Department of Energy and Mines (NSDEM) and the Department of Natural Resources and Renewables have instituted an Abandoned Mine Openings (AMO) Remediation Program to address AMO’s on Crown land. ![]() Anyone who may be traveling in an undeveloped area known to potentially contain abandoned mine openings should review the Nova Scotia Department of Natural Resources Information Circular ME 42, 1995 - A Sign to Watch Your Step. At some mines, signs on Crown and private land identify the locations of open holes and hazards however, many more of these abandoned mine openings have no warning signs posted. Most abandoned mine sites contain unsecured open holes and tunnels which present hazards to the public.
