The King Midas Lynch adit is located on the north side of Fault Creek, approximately 50 metres from the mouth of Fault Creek on the Zeballos River.

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.

Locally, a 0.8 to 5.0-centimetre wide quartz-calcite vein, striking north and dipping vertically, is present in andesite. A 15 to 25-centimetre wide silicified shear zone, located 15 metres uphill, with sphalerite, chalcopyrite, pyrite and pyrrhotite has been explored by several opencuts. A sample of oxidized material assayed 63.09 grams per tonne gold, 6.86 grams per tonne silver, 0.5 per cent copper and 2.8 per cent zinc (Bulletin 27, page 116).

On the south bank of Fault Creek, a 7.5 to 15-centimetre shear zone striking 020 degrees and dipping 45 degrees south contains banded quartz with arsenopyrite. A sample assayed 20.57 grams per tonne gold and 3.4 grams per tonne silver (Bulletin 27, page 116).

In 1938, a sample from the ‘east’ vein assayed 37.3 grams per tonne gold, whereas sampling of the ‘west’ vein assayed 17.1 and 37.3 grams per tonne gold with an average of 28.4 grams per tonne gold over 10 centimetres from the two veins (Property File - C.C. Starr [1938-05-03]: Report on the King Midas Mine). The veins were reported to likely join to the north and were thought to be a possible continuation of the King Midas No. 1 (MINFILE 092L 020) vein.

An adit and several opencuts of unknown age, but likely dating to the 1930s, are reported at the occurrence. 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 2003, Canalska Ventures Ltd. completed a regional program of rock, silt and soil sampling on the area. In 2009, Global Silver Producers Ltd. and A25 Gold Producers Corp. prospected the area.
