Question: Which of the following Canadian gold mines was operated by Royal Oak Mines from 1998-1999: Kemess Mine or Bralorne?
Context: Osisko is a Canadian precious-metals mining company headquartered in Montreal, Quebec.  It operates in Canada with a focus on gold mines in the Abitibi gold belt of Quebec.  The company was known as Osisko Exploration LTD. before changing its name in May 2008.  It owns at least 17.41 e6ozt of gold reserves (including 10.71 in malartic and 6.7 at Hammond Reef, malartic reserves up 20% in March 2011 due to higher gold prices) and over 230 km2 of land in the Malartic-Cadillac area.  Based on market capitalization, it is one of Canada's largest Canadian gold mining companies.  The Canadian Malartic mine will be the biggest gold mine ever in Quebec and one of the biggest gold mines in Canada. George A. Dondero High School (formerly Royal Oak High School) was opened in 1927 in Royal Oak, Michigan in Greater Detroit.  It was named after former United States congressman and Royal Oak School Board President George A. Dondero.  A part of the Royal Oak Neighborhood Schools, it was merged into the new Royal Oak High School. The N.W.T. Mining Heritage Society, in the Northwest Territories, Canada, was first formed in early 2000 as the Giant Mine Heritage Group to rescue items from the Giant Mine site after its owner, Royal Oak Mines Incorporated, went bankrupt. 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. 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. Bralorne is an historic Canadian gold mining community in the Bridge River District, some eighty dirt road miles west of the town of Lillooet. Hutti Gold Mines Limited () (HGML) is a company located in the state of Karnataka, India and engaged in the mining and production of gold.  This was first established as Hyderabad Gold Mines in 1947.  With the closing of Kolar Gold Fields in 2001, this is the only company in India which produces gold by mining and processing the gold ore.  Owned by the Government of Karnataka, HGML has two plants located in Hutti and Chitradurga.  HGML mines gold from its main gold mine located in Hutti and other satellite mines. Cadwallader Creek is an important tributary of the Hurley River in the Bridge River Country of the British Columbia Interior, Canada, most notable for its role as the home of the Bralorne and Pioneer Mines and associated gold claims and workings.  Less than twenty miles in length, the creek is joined by Noel Creek within the area of the town of Bralorne, and just below Bralorne joins the Hurley River just above Hurley Falls and that river's ten-mile canyon prior to its own confluence with the Bridge River near the town Gold Bridge.  Standard Creek, a short tributary of Cadwallader Creek near its upper end, connects via McGillvray Pass to the creek of the same name and, on Anderson Lake far below, the resort townlet of McGillivray Falls.  One-time plans to build a cog railway to the mines from the Pacific Great Eastern at McGillivary Falls were never fulfilled. 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. The Dolaucothi Gold Mines (Welsh: "Mwynfeydd Aur Dolaucothi" ) (grid reference [ SN662403] ), also known as the Ogofau Gold Mine, are ancient Roman surface and underground mines located in the valley of the River Cothi, near Pumsaint, Carmarthenshire, Wales.  The gold mines are located within the Dolaucothi Estate which is now owned by the National Trust.
