Low-grade mineralization encountered in both SEP06-114 and SEP06-115 occurs above the andesite in tuffaceous rock, possibly associated with a newly recognized high-angle fault.
The mineralization appears to be associated with a northwest trending dike within a high-angle fault, a structural association common at Jerritt Canyon.
With the existing assayed high-grade drill hole located along the high-angle fault, data was available to aid in the decision to begin the drill program.
A high-angle fault displaces the mineralized body on the west side, apparently down-dropping it.
The next phase of work will involve a limited induced polarization (IP) geophysical study, to aid in the better definition of drill targets and the possible identification of high-angle faults associated with jasperoids and expected pyrite-stibnite mineralization at depth.
Points of maximum slope on the GRAVIS were determined and where such points form prominent linear features, they have been interpreted as high-angle faults in the basement.
The veins at Fire Creek are primarily hosted by high-angle faults in brittle mafic rocks.
As many as six types of mineralization are present, including veins related to diorite dikes, high-angle faults, low-angle faults, and thrust faults; and disseminated mineralization in shale and sandstone related to detachment faults.
The geology consists of fine-grained Ordovician sedimentary rocks intruded by a dacite porphyry and crosscut by northwest and north-south striking high-angle faults.
