Core Viewpoint - Rise Gold Corp. has initiated a review of historical data suggesting that its Idaho-Maryland mine may contain significant tungsten deposits, which are critical for U.S. defense applications [1][4]. Company Overview - Rise Gold Corp. is an exploration-stage mining company based in Nevada, USA, with its principal asset being the historic Idaho-Maryland Gold Mine located in California [8]. Historical Context - The Idaho-Maryland mine operated from 1862 to 1957, producing approximately 2.4 million ounces of gold at an average grade of 0.50 ounces per ton [2]. - In 1954, the mine began exploring for tungsten, leading to the production of tungsten trioxide concentrate until operations were suspended in 1957 due to a significant drop in tungsten prices [3]. Tungsten Significance - Tungsten is classified as a critical mineral by the U.S. government, essential for various defense applications, and the U.S. has not had a domestic supply since 2015 [4]. - China currently dominates global tungsten production, accounting for 84% of the supply, and has recently imposed restrictions on tungsten exports [4]. Exploration and Development Plans - The company has engaged experts to review historical tungsten data and generate recommendations for further exploration, which may include re-assaying existing drill cores [7]. - The historical association of the Idaho-Maryland mine with tungsten has made it a candidate for federal sponsorship as the U.S. seeks to reshore its critical defense industries [5].
