GEOLOGY

In September 2024, Yukon Metals conducted a helicopter-supported mapping and sampling program on its AZ property. A prominent zone of orange iron-stained and altered rocks was followed over 1.2 kilometres on the north and eastern flanks of Chair Mountain. Consistent copper mineralization was found along the prospected area. Of the sixty rock-chip samples taken, 18 samples showing significant copper content, assayed from 0.12-3.49%. 

Hematite alteration was also noted in the area. This can be associated with oxidized hydrothermal fluids, which are key drivers in forming major porphyry copper deposits.

Rock-chip samples were collected in quartz veins within basalt and andesite volcanic rocks in both outcrop and float exposures near the ridge tops. This area is coincident with a major topographic lineament, mapped regionally as a NW trending fault zone, that extends a further kilometer down to Sanpete Creek (a past alluvial gold producer) and the property boundary to the southeast.

The large gossan and mineralized veins provide evidence of a large hydrothermal system driving fluids through the faults and fractures on Chair Mountain. Strongly clay-altered biotite-quartz diorite dykes were mapped in the vicinity of mineralization and are interpreted to be part of the Nutzotin suite of intrusions.
