Lower plate Carlin system in the Callaghan Window

Located in Nevada


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 7.5 km strike length.

Historic work includes a 1986 drill program by Brican Resources, which intercepted 30’ of 1.6 ppm Au along with a handful of additional anomalous intercepts.  In the northern project area, a 2011 reconnaissance 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.
