Question: What mine was operated by Royal Oak Mines at at earlier date, Kemess Mine or Colomac Mine?

Documents:
source: Colomac Mine
text: 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.

text: Kemess Mine The Kemess Mine was an open-pit copper and gold mine, located just northeast of the foot of Thutade Lake, at the head of the Finlay River, in the Omineca Mountains of the Northern Interior of British Columbia, Canada. It was operated by Royal Oak Mines from 1998 to 1999, when it was bought by Northgate Minerals. Northgate operated the mine until its closure in 2011; that year Northgate was taken over by AuRico Gold. In 2014 AuRico Gold partitioned off its portion of kemess Mine ownership creating a new company called AuRico Metals. AuRico Metals is actively implementing permits for a block caving mine.

source: Thutade Lake
text: Thutade Lake Thutade Lake is located in the Omineca Mountains of the Northern Interior of British Columbia, Canada. About 40 km in length, and no more than about 2 km wide, the lake is primarily significant as the ultimate source of the Mackenzie River. The lake is at the head of the Finlay River, which joins the Peace River via Williston Lake. The area is very remote, being located about 260 km north of Smithers, although several mining operations for ores containing copper, lead, zinc and silver have occurred around the lake. The largest of these is the Kemess Mine, an iron and copper property originally owned by Royal Oak Mines and now by Northgate Minerals, located in the valley of Kemess Creek, which is off the northeast end of Thutade Lake. The mine is accessed by the Omineca Resource Road and other resource routes, and is 400 km by road from Prince George. Just downstream from the outlet of Thutade Lake, the Finlay plunges over 180 ft Cascadero Falls, and then through a series of cataracts in a twisting course until it begins its main northeastward trend. Cascadero Falls is slated for hydroelectric development in connection with the power needs of the area's mines.

source: P3 Mk2 mine
text: P3 Mk2 mine The P2 Mk2 and P3 Mk2 are Pakistani plastic cased minimum metal anti-tank blast mines. The P2 Mk2 has a square case with a central circular ribbed pressure plate, the P3 is circular with a central circular pressure plate. Both mines use anti-personnel mines as the fuse, typically the either the P4 Mk1 or P2 Mk2 anti-personnel mines. The anti-personnel mine sits in a cavity below the pressure plate, when enough pressure is place on the pressure plate of the mine, it collapses onto the anti-personnel mine triggering it and the main charge which sits below it. A yellow canvas carrying strap is normally fitted to the side of the mine. The mines have a secondary fuse well on the bottom which can be used with anti-handling devices. A GLM-2 electronic booby trap can be fitted to the cavity under the pressure plate. The mine is supplied with a steel disc which makes the mine more easily detectable, although this is seldom used. Since 1997 only a detectable version of the mine has been produced, and to comply with the Convention on Conventional Weapons amended protocol II, Pakistani stocks of the mine are being retrofitted with steel detection discs. The mines are found in Afghanistan, Angola, Eritrea, Ethiopia, Pakistan, Somalia, and Tajikistan.

text: National Mine Map Repository The National Mine Map Repository (NMMR) is part of the United States Department of the Interior (DOI), Office of Surface Mining Reclamation and Enforcement (OSMRE or OSM). The NMMR resides in the Pittsburgh suburb of Green Tree, Pennsylvania, and collects and maintains mine map information and images for the entire country, including data and maps of coal mines in the anthracite coal region of northeastern Pennsylvania. The Green Tree facility provides and stores, digitally and in microfilm (aperture cards), over 182,000 maps of abandoned mines. This repository contains maps of mine workings from the 1790s to the present day. It serves as a point of reference for mine maps and other information for both surface and underground mines throughout the United States. It also serves as a location to retrieve mine maps in an emergency. The NMMR provides services ranging from retrieving mine related data for economic analysis to assessing the potential risk associated with underground mining. Through analysis of mine maps and related information, the repository assists private and public sectors in industrial and commercial development, highway construction, and the preservation of public health, safety, and welfare. In addition, they collect, reproduce, and maintain a national inventory of mine maps and supporting documentation for private and public interests.

text: Cascadero Falls Cascadero Falls is a waterfall on the Finlay River in the Northern Interior of British Columbia, Canada, located just below that river's head at the outlet of Thutade Lake. The height of the falls is 180 ft and below it there are numerous cascades or rapids in a twisting course prior to the river's general northeastward trend from this area. The falls are slated for hydroelectric development in connection with the area's mines, the largest of which is the Kemess Mine owned by Northgate Minerals Inc., located just east of the foot of Thutade Lake in the valley of Kemess Creek.
