The Ford occurrence is located on the western slopes of Mount Dewdney, in the north eastern head waters of Eighteen Mile Creek.

The area is underlain by Permian to Jurassic Hozameen Complex rocks comprised mainly of interbedded chert, pelite and basic volcanics. The Hozameen fault traverses south-southeast separating the lower greenschist facies rocks of the Hozameen Complex from the unmetamorphosed Mesozoic rocks of the Ladner Group to the east.

The Lower-Middle Jurassic Dewdney Creek Formation (Ladner Group) consists of a sequence of well-bedded sediments comprised of interbedded argillite, siltstone, wacke, sandstone and conglomerate. Local quartz stockworks and diorite dikes, ranging up to 30 metres in width, crosscut the strata. The siltstone and wacke is highly silicified near the dike contacts. Disseminated pyrite occurs in the silicified siltstone and some beds are heavily oxidized with extensive limonitic staining.

Locally, the Hozameen Complex consists of ribboned cherts with interbedded schistose bands and an andesitic volcaniclastic unit. The rocks have undergone greenschist facies metamorphism and local silicification. In the western part of the property, a chert unit is highly silicified and intruded by aplite dikes. In this sequence, quartz veins up to 15 centimetres in width, crosscut and locally flood the chert.

Several rock samples were collected and averaged 0.1 gram per tonne silver, 0.01 gram per tonne gold with traces of copper, lead and zinc. A sample (75450) taken near the headwaters of Eighteen Mile Creek assayed 0.18 gram per tonne gold and 0.5 gram per tonne silver (Assessment Report 13270).

In 1984, Placer Development completed a program of geological mapping and rock, silt and soil sampling on the area as the Ford 1-6 claims. In 2006 and 2007, the area was prospected as the Sumalo Five claim.
