The King Midas Trail vein occurrence is located east of the Zeballos River and north of Fault Creek at an elevation of approximately 185 metres on the Yuaco No. 6 (L.1668) Crown grant.

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 Trail (Yauco No. 6) vein consists of a 2.5 to 10-centimetre wide quartz vein with pyrite, chalcopyrite and pyrrhotite with minor sphalerite hosted by volcanics of the Karmutsen Formation. The vein strikes 010 degrees with a dip of 65 to 90 degrees east and has been intermittently traced for 550 metres along strike. The vein lies approximately 75 metres east of and parallel to the Contact vein (MINFILE 092L 216), which it is believed to merge with to the south.

In 1938, sampling of the Yuaco No. 6 (King Midas-Trail) vein yielded from 0.5 to 1.0 gram per tonne gold (Property File - C.C. Starr [1938-05-03]: Report on the King Midas Mine).

In 1950, a sample by Stevenson assayedtrace gold and silver and 0.8 per cent copper (Bulletin 27, page 117).

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.
