Title: List of Lupin the Third Part I episodes
Passage: Lupin the Third Part I (ルパン三世 , Rupan Sansei ) is the first TV anime adaptation of Monkey Punch's manga series of the same name.  Produced by Yomiuri Telecasting Corporation and Tokyo Movie, with character designs by Yasuo Ōtsuka, it was directed originally by Masaaki Ōsumi and later by Hayao Miyazaki and Isao Takahata under the name "A Productions".  It aired on Yomiuri Telecasting Corporation in two seasons from October 24, 1971 to March 26, 1972, the first 11 episodes being of the first season and the latter 12 of the second.  The series centers on the adventures of Arsène Lupin III, the grandson of Arsène Lupin, the gentleman thief of Maurice Leblanc's series of novels.  He is joined by Daisuke Jigen, Lupin's closest ally; Fujiko Mine, the "femme fatale" and Lupin's love interest who works against Lupin more often than with him; and Goemon Ishikawa XIII, a master swordsman and a descendant of Ishikawa Goemon, the legendary Japanese bandit.  Lupin is often chased by Inspector Zenigata of the Tokyo Metropolitan Police, a descendant of Zenigata Heiji.  A rather cynical detective, Zenigata has made it his life's mission to chase Lupin across the globe in hopes of arresting him.
Title: Lupin Mine
Passage: 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.
Title: Hedley Mascot Mine
Passage: 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.
