Real mining at Bartlett Mountain started in the 1910s. Molybdenum demand increased sharply that decade, first as European countries geared up for war and then as World War I demonstrated the clear superiority of molybdenum-strengthened steel. The major local breakthrough came in 1915, when Otis King developed a process for separating molybdenum ...
