Colomac Mine
The Colomac Mine was a privately owned and operated open pit gold mine located 220 km northwest of Yellowknife in the Northwest Territories in Canada . The Colomac mine operated between 1990–1992, and 1994–1997. It was operated by Neptune Resources Limited that had little success in making a profit during its operation. In 1994, the mine had reopened under Royal Oak Mines Inc. Both Neptune Resources and Royal Oak Mines where both owned and operated by Peggy Witte. Due to low gold prices and high cost of mining, Royal Oak Mines was forced into bankruptcy. The Federal Government of  Canada became owners of the mine, along with the related environmental issues. A major cleanup effort is under way to prevent the mine from polluting the environment, but this might be too late at this stage. This mine is now owned and controlled by the Indigenous and Northern Affairs department of the Federal government, while Public Works and Government services is the current contracting authority. Production. The Colomac Mine processed a total of almost 12,300 Megagrams of ore, and produced 16.7 Megagrams (535,708 troy ounces) of gold, with an approximate value of $916 million. This figure is based on  2012 gold prices, averaging close to USD $55,000 per kg. In April 2007, Indian and Northern Affairs Canada engaged the Professional Services company Deloitte & Touche LLP to become their solicitor, in order to find another independently-owned and -operated company to acquire the idle mine as well as the resources on the land it occupied. To generate interest, they featured the mine as holding 6.6 Teragrams of untapped resources, a gold processing mill and related equipment, a maintenance building, a dorm room styled housing complex, power and fuel storage facilities, and mobile equipment (rock trucks, excavators and loaders). It  was also featured on the popular reality television show "Ice Road Truckers". Cleanup. After being shut down in 1997 and abandoned shortly after by Royal Oak Mines, it transferred into the Canadian Government's hands and responsibility in mid-December 1999. In accordance with water licensing laws and regulations in Canada, Royal Oak Mines had posted a $1.5 million security deposit and in 1999 they were charged with cyanide dumping by the Federal Government. The government of Canada had estimated the cost of the cleanup at $70 million due to high levels of cyanide and ammonia content, as  well as acid mine drainage. For the people of Indian Lake the tailing pond owned by the mine was at one stage threatening to overflow unless immediate action was taken to prevent a disastrous environmental impact. A public hearing was called to cancel the mines' license and to begin a cleanup. In 1999, the Department of Indian Affairs and Northern Development (DIAND) awarded a one-year, $2 million contract to a consortium of aboriginal businesses from DetonÇho Corporation, the Dogrib Rae Band and the North Slave Métis Alliance to undertake final reclamation activities at the Colomac Mine. The consortium  conducted studies into contamination and took responsibility for on-going environmental monitoring and maintenance of the site. After the contract was awarded, Royal Oak Mine was finally charged under the Water Act and the Fisheries Act for the pollution it had caused, this was much too late, since the company was already in receivership. According to MineWatch Canada in a 2001 publication: "Now, the water license has not been changed, the money needed to clean-up the site is not forthcoming, and the Dogribs are faced with a potential catastrophe if the tailings pond overflows. Says Dogrib leader Ted Blondin : "I think there is a fiduciary responsibility that the federal government has to looking after the Dogrib interests, and these are the arguments that we will use towards ensuring that the quality of water and the work that has to be done for the cleanup is done." During the initial cleanup phase, many new and effective remediation procedures where developed and put into place, including the use of farmed micro-organisms to remove hydrocarbons from soil contaminated by poor management of the fuel tank farm located on site. On 25 February 2010 a $19 million contract was awarded to  two aboriginal firms, Tlicho Engineering/Environmental Services Ltd and Aboriginal Engineering Ltd for a final two year remediation contract, which will also create local jobs in the area. According to Aboriginal Affairs and Northern Development Canada this two year remediation will cover: "final remediation of the site, including: major demolition activities (primary and secondary crushing facilities, mill complex, maintenance shop and camp); hydrocarbon remediation (restoration of Steeve's Lake shoreline, free product recovery and soil treatment); site restoration (Truck Lake channel construction, stream crossing restoration) and capping of the non-hazardous landfill sites as well as continued provision of site  services and maintenance. The contract, which follows a competitive process, will last until April of 2012 when the companies will conduct a full and final demobilization of the site." In May 2010, officials suspended the remediation project due to an accident, which occurred at mine in April 2010. It occurred after a foremen working for Aboriginal Engineering Ltd suffered leg injuries after a 2.5 cm cable snapped. Human Resources and Skills Canada announced in May 2010 that they would not allow this remediation to continue until Aboriginal Engineering Ltd set out to implement the standards for health and safety set  out by the Federal Government in relation to this type of task.
