  • Anomalous gold in soil over 3 x 2.5 km with untested high priority follow up areas with significant gold- and copper-in-soil
  • Rock samples have returned up to 12.55 g/t gold with 93.10 g/t silver
  • Potential for regional-scale epithermal vein mineralization

Rosy Geology

The Rosy property is predominantly underlain by Devonian to Mississippian aged metasedimentary and metavolcanic rock of the Yukon-Tanana Terrane. The southern end of the property has been intruded by 184.28 ± 0.07 Ma Early Jurassic Sawtooth Pluton, which is composed of weakly foliated hornblende-biotite granodiorite. In the northern part of the property, the 81.2 ± 0.9 Ma Late Cretaceous quartz monzonite Boswell Pluton, which hosts the Red Mountain Molybdenum deposit, intrudes Yukon-Tanana rocks. Numerous cream-to-pink weathering quartz-feldspar porphyry dykes cut the Sawtooth Pluton and are commonly flanked by quartz-carbonate veins and/or carbonate altered wallrock. Primary structural features in the southern part of the property are a series of strong north-south trending linears and less obvious, secondary northeast-southwest trending linears that cut the primary structural trend.

Rosy Mineralization

The Rosy property mineralization demonstrates an epithermal gold-silver characteristic with two main types of mineralization discovered to date. The first consists of low sulphidation, epithermal, (often chalcedonic) quartz-carbonate veins in the southern part of the property, These veins consist of stringers, blebs and disseminated pyrite, lesser arsenopyrite and rare chalcopyrite and typically account for 1% to 10% of the vein. On weathered surfaces, sulphides have been oxidized and leached to produce limonitic pits.

The second style of mineralization is found in quartz-feldspar porphyry dykes within the Sawtooth Pluton, consisting of trace pyrite and rare arsenopyrite which weathers to give a gossanous appearance.

Key showings on the Rosy property include the R1-R4 veins and A-D soil anomalies. The R1-R4 veins are weakly defined and consist of quartz-carbonate that host pyrite and arsenopyrite. Soil anomalies A-D occur within a 3 x 2.5 km area with gold-in-soil values up to 1,820 ppb gold.
