About Erdene

Erdene Resource Development Corp. is a Canada-based resource company focused on the acquisition, exploration, and development of base and precious metals in underexplored and highly prospective Mongolia. The Company has interests in four exploration licenses and a mining license in southwest Mongolia, where exploration success has led to the discovery and definition of several prospects and deposits including: Bayan Khundii - the Company's flagship and newly discovered, high-grade, near-surface gold project; Altan Nar - an extensive, high-grade, near-surface, gold-polymetallic project located 16 kilometres northwest of Bayan Khundii; Altan Arrow - an early-stage, high-grade gold-silver project 3.5 kilometres north of Bayan Khundii; Ulaan - a recently acquired copper-gold porphyry prospect adjacent to Bayan Khundii; Khuvyn Khar - an early-stage, copper-silver porphyry project; Nomin Tal - a narrow, high-grade copper-gold discovery; and Zuun Mod - a large molybdenum-copper porph yry deposit. In addition to the above projects, Erdene has an Alliance with Teck Resources Limited on regional copper-gold exploration in the prospective Trans Altai region of southwest Mongolia. The Bayan Khundii and Altan Nar licenses have a 2% net smelter returns royalty ("NSR Royalty") in favour of Sandstorm Gold Ltd. with a buy-back option to reduce the NSR Royalty to 1%.
