White Mountain is an epithermal gold exploration project located approximately 300km south-southwest of Salt Lake City and 25km southwest from the town of Milford in Utah, USA.
Alderan has a 100% interest in tenements covering 7.6km2.
The geology of the area consists primarily of Miocene age rhyolites, tuff and basalt. The prominent Brimstone Fault runs east-west through the area and can be seen on ground magnetics which were completed by Alderan. A 5km argillic, phyllic and siliceous alteration zone has been mapped through the area largely centred around this fault. Within the alteration zone there is evidence of sinter terraces, alunite and a chalcedony blanket plus there is an historical sulphur mine – all indicators of an epithermal system.
Alderan has completed ground magnetics over the area and reconnaissance geological check mapping and limited rock sampling. The mapping confirmed the geology, structure and alteration zones while the rock samples contained low gold grades typical of epithermal systems however mercury, silver and barium were elevated in some samples. The magnetics defined the trace of the Brimstone Fault and a number of additional structures.
White Mountain displays all the characteristics of being capable of hosting two styles of epithermal gold deposit:
- Bonanza fault-hosted gold-bearing banded quartz vein and
- Disseminated, stratabound gold within an initially porous permeable volcanic host rock.
