The Monitor occurrence lies in the eastern end of the Zeballos camp and is located south of the Nomash River, approximately 1 kilometre south-southeast of its junction with Curly Creek.

Regionally, the area is underlain by Upper Triassic to Lower Jurassic Bonanza Group basaltic to rhyolitic volcanic rocks. Conformably underlying the Bonanza volcanic rocks are limestones and limy clastics of the Triassic to Lower Jurassic Parson Bay Formation (Bonanza and Vancouver groups) and Upper Triassic Quatsino Formation (Vancouver Group), and tholeiitic basalts of the Upper Triassic Karmutsen Formation (Vancouver Group). Dioritic to granodioritic plutons of the Zeballos intrusion phase of the Jurassic Island Plutonic Suite have intruded all older rocks. The Zeballos stock, a quartz diorite phase of the Eocene to Oligocene Mount Washington Plutonic Suite, is spatially related to gold-quartz veining in the area. Bedded rocks are predominantly northwest striking, southwest dipping, and anticlinally folded about a northwest axis.

Locally, several narrow (up to 5 centimetres wide) quartz veins with pyrite and native gold are hosted in a shear zone, up to 15 cetimetres wide, in granodiorite. The veins strike 280 to 295 degrees and are steeply dipping.

Other zones of mineralization are reported to include massive copper sulphide (chalcopyrite?) mineralization occurring as replacements in limestone of the Quatsino Formation near the intrusive contact. No further information is available on the replacement mineralization (Geological Survey of Canada Paper 40-12, page 34).

During the 1930s or early 1940s, several short adits were driven on the veins.

In 2017, the area was prospected and sampled (rock and soil) as the Santa Barbara claims. Also, at this time Pacific West Stone Inc. completed a program of prospecting, geological mapping and rock sampling on the area. This work was directed towards limestone and dimension stone evaluation.
