Robber Gulch PropertyIdaho, U.S.A.
- Large land position in an underexplored district north of Nevada’s Carlin Trend.
- Shallow, heap-leachable oxide gold targets < 250 m deep along >2 Km strike length.
- Straightforward permitting on BLM claims.
- Structural complexity and multiple generations of normal faults: multiple targets.
- Alteration exposed in erosional window and extends beneath volcanic cover.
- Historic drill intercepts: AC-4: 18.3m of 0.23 g/t Au and 24.4m of 0.56 g/t Au including 6.1m of 1.25 g/t Au in oxide, true thicknesses of intercept unknown.2
- Same host rocks as Liberty Gold’s Black Pine.1
- Location: 30 km SW of Burley, Idaho, with lodging, food, and Interstate 90.
- Access: Paved and gravel roads from Burley. Maintained drill roads onsite.
- Claims: 3.4 km2. Dominantly BLM land. Minor USFS unpatented lode claims.
- Ownership: Option to earn 100%.
- Infrastructure: Low power costs. Rail line 30 km NE. 34 KV transmission line 1 km NE.
- Permitting: BLM. Notice of intent drill permits in 30 days.
- Host rocks: Penn-Permian Oquirrh Formation (various local members) silty limestone, calcareous sandstone. Exposed in erosional window through post-mineral volcanics.
- Structure: N-S striking, steeply W-dipping faults are primary fluid conduits. Bedding serves as secondary fluid pathways. Previous work focused on NW striking structures, now understood as post-mineral.
- Alteration: Jasperoid and minor decalcification in silty limestone. Silicification and qtz-goethite veining in calcareous sandstone.
- Geochemistry: Au-Ag-As-Sb correlation in rock chips.
The primary targets at Robber Gulch are surface-mineable, oxide Carlin-style gold mineralization associated with intense jasperoid, decalcified limestone, and local quartz veining and brecciation within sandstone and carbonate units.
- Heap-leachable oxide gold at target depths < 250 m.
- Same host stratigraphy as Black Pine mine, Oquirrh Formation.1
- Mineralized fluid conduits extend under post-mineral cover.
- Minimal outcrop, no previous soil geochemistry.
- Widespread alteration and anomalous Au-Ag-As-Sb-Hg in rock chips.
- Follow up of historic drill intercepts.
