The King Midas-Contact vein occurrence is located north of Fault Creek and approximately 30 metres east of the Zeballos River at an elevation of approximately 150 metres. This is located near the eastern corner of the Big Ben 3 and 4 Crown grants.

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 Group) and Upper Triassic Quatsino Formation (Vancouver Group), and the 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. A north-south–striking fault occurs along the Zeballos River valley, north of the rivers junction with the Nomash River.

The King Midas-Contact (Glory Hole and Mark’s) vein is 2.5 to 13 centimetres wide and follows a 13 to 25-centimetre wide shear zone. The quartz-gangue contains pyrite, chalcopyrite and pyrrhotite. The vein strikes 355 degrees with a dip of 75 degrees east and has been traced for 260 metres. The vein occurs at the contact between Quatsino limestone and Karmutsen andesitic greenstone. The Contact vein lies approximately 75 metres west of the King Midas Trail (MINFILE 092L 217) vein and is believed to converge with the previous vein to the south.

A sample of ‘typical’ vein material assayed 6.86 grams per tonne gold and trace silver (Bulletin 27, page 117).

In 1938, sampling of the vein averaged 22.6 grams per tonne gold (Property File - C.C. Starr [1938-05-03]: Report on the King Midas Mine).

In 1931, the area was explored as the Ehatset claims. In 1938, the King Midas Mining Co. Ltd. was operating on the property. In 1979, Esperanza Explorations completed a program of regional silt sampling and prospecting on the area. In 1999, the area was prospected by the Zeballos Mining Company as the Zeb Au claim. In 2009, Global Silver Producers Ltd. and A25 Gold Producers Corp. prospected the area.
