Capsule
The area was sampled first in 1967 by a regional program which identified silt anomalies across Earn Group stratigraphy.
The Bach occurrence is located within the Selwyn Basin which consists of shallow shelf to off-shelf marine clastic and chemical sediments, as well as basinal clastic sediments derived from the Ancient North American Platform to the north-east. The occurrence occurs along the western limit of a broad deformation belt unofficially called the "Gold River Fold Belt'.
The occurrence is underlain by an ESE trending package of Road River Group shale with minor chert extending along an ESE trending contact with a broad package of Road River Group chert with lesser shale and siltstone to the north. The southern shale package, which contains a small phyllite member, lies in contact with a unit of Earn Group chert pebble conglomerate to the south. A smaller unit of Earn Group conglomerate extends along western portions of the shale-chert contact.
The location of the occurrence is coincident with a gold in soil anomaly and coincides with geological contacts and structures on the property.
