Question: Which was opened first, the Lupin Mine or the Hedley Mascot Mine?
Context: The Samira Hill Gold Mine (fr.  "Mine d'Or du Mont Samira") is a Gold mine in Téra Department of the Tillabéri Region in Niger.  Opened in late 2004, it is the first industrial scale gold mine in the nation, and while operated by a Canadian/Moroccan consortia, the government of Niger owns both a 20% stake in its operation, and functions under government concession.  The mine, and the possibility that other gold concessions will follow, is projected to be an important component of future export revenue for the West African state. Lupin Mine was a gold mine in Nunavut Territory, Canada.  It opened in 1982 and was originally owned and operated by Echo Bay Mines Limited, who in 2003 became a fully owned subsidiary of Kinross Gold Corporation. The Hedley Mascot Mine was a gold mine in Hedley, British Columbia, Canada.  Gold was first discovered in the Nickel Plate Mountain area in 1897 and several small mines were developed over the years.  The Hedley Mascot Mine operated between 1936 and 1949 and was one of the most unusual mining operations in the world, being built entirely on the side of a mountain, 5,000 feet above the town of Hedley or seven thousand feet above sea level.  In the 1990s, the British Columbia government was going to burn the site down because it posed a safety risk, but the Minister of Tourism at the time intervened and, in 1995, steps were taken to preserve the site as a Provincial Heritage resource. Anina Coal Mine is an underground mine that is now closed.  It was one of the largest mines in Romania.

It was owned by Miniera Banat a state owned company that specialised in the management of coal mines in the Banat region.  The mine opened in 1790 making it the longest running mine in Romania until its closure in 2006.  Its galleries are hundreds of kilometers in length and reach a depth of 1200 m making it the deepest mine in Romania and one of the deepest in Europe.  The mine supplied oil shale to the nearby Crivina Power Station, a 990 MW thermal power station, the first oil shale power station in Romania, that had to be supplied with around 4 million tonnes of oil shale per year.
