Silver Dome




The Silver Dome Project is 100% owned by Allegiant, subject to underlying royalties, and is located 72 km northwest of Delta, Utah, along the western margin of the Fish Springs Mountains.

In 2008, Columbus drilled 13 rotary holes targeting bulk-tonnage silver mineralization near the Cactus Mine. Although silver was encountered in the drill campaign, the results did not justify further work in the area of drilling. However, a mag survey completed during this phase of exploration discovered a circular magnetic high, lying under valley fill just to the southwest of the Cactus Mine. This mag high is interpreted as the signature of a shallow buried intrusive, which presents an excellent drill target for copper, zinc, indium and silver especially along its margins. The intrusive is interpreted to be about 0.8 km. in diameter.

The region is known for mineralization both within intrusive rocks and their associated skarns. The Crypto zinc-copper-indium skarn deposit lies immediately north of the Cactus mine. Lithic Resources Ltd. published a 43-101 report on the Crypto deposit by Mine Development Associates in 2010. Mine Development reports the total of indicated and inferred resources at Crypto at 25.5 million tonnes at 6.3% zinc equivalent. One of the largest copper mines in the world, Bingham Canyon, is about 150 km northeast of Silver Dome. Bingham Canyon has produced over 15.4 tonnes of copper, 23 million ounces of gold, 190 million ounces of silver, and 850 million pounds of molybdenum, largely from classic porphyry copper mineralization with associated skarn mineralization.
