North Lily Mine
The North Lily mine is an historic underground mining operation within TCM’s East Tintic property, that is of note because of the extremely high-grade gold rich ores that were historically mined from the End-line Dyke fissure where 65,000 tons of ore were mined at an average grade of 1.326 opt gold, 4.75 opt silver and 1.37% copper. The mine ceased operations in 1949 with total production of 377,000 tons of ore containing 151,000 ounces of gold, 3.48 million ounces of silver, 2,915,000 pounds of copper and lesser lead and zinc. Production was halted at the 1600 level where mining intersected the groundwater table.
The North Lily deposit is characterized by very high-grade gold-rich ores that were mined from structurally controlled siliceous vein breccias within the Tintic Quartzite, as well as overlying carbonate replacement lead-zinc-silver ores along the thrust faulted contact with the Tintic Quartzite. Of note, a selected sample historically taken from the gold rich End-line Dike fissure assayed an exceptional 9.25 % gold (2,221 opt Au), 44.14 % copper, 0.72 % silver, 27.43 % sulfur, 13.98 % arsenic and lesser antimony and iron.
The North Lily mine (and other historically producing mines) offer TCM an exciting pipeline of advanced exploration targets to pursue. Because of the extremely high-grade gold ores historically mined in and around the North Lily operation, the next focus of TCM beyond the re-opening of the Trixie mine is to employ the same approach of historic data collation using modern mining software, 3D modeling and re-interpretation of the legacy data to identify gold focused targets for an aggressive program of exploration drilling.
Potential drill targets will include the at-depth extension below the water table of the very high-grade gold ores associated with the northeast trending fissure faults, and the potential for along-strike and sub-parallel gold-rich ore zones potentially developed within the favorable Tintic Quartzite host rock at depth.
