Lower plate Carlin system in the Callaghan Window
Target: Carlin-style gold deposit
Location: Lander County, Nevada, USA
Size: 15.7 km2
Status: 188 lode claims on federal land administered by the BLM
Stage: Preliminary mapping and sampling underway, following on from historic magnetics, and gravity, and reconnaissance drilling
The Callaghan project is an early-stage exploration project with historically demonstrated Carlin-style gold mineralization. The project is located along the eastern side of the Callaghan Window, which exposes lower plate Paleozoic rocks along the core of a broad anticlinal feature. The trace of the Roberts Mountain Thrust – a regional deformation horizon that often marks the hanging wall of Carlin-type deposits – is located along the southern and northern margins of the project area, and locally hosts gold mineralization. Within the Callaghan project area, gold and elevated trace elements including As, Sb, and Hg occur within decalcified sandstones, siltstones; and within spongey jasperoid breccias along a 7.5kmstrike length. Although a portion of the system outcrops, a majority of the targets exist under shallow (
Historic work includes a 1986 drill program by Brican Resources, which intercepted 30’of 1.6ppm Au along with a handful of additional anomalous intercepts. In the northern project area, a 2011reconnaissance drill program was conducted by Kinross, which yielded anomalous intercepts and demonstrated a shallow depth to bedrock (75 feet) in the pediment cover. Neither drill program was followed up.
