The Hot 1 occurrence is located approximately 36.5 kilometres northeast of Kimberley, and at the headwaters of Nicol Creek, just west of Wildhorse River.

At the Hot 1 showing, minor copper mineralization occurs as fracture-fillings associated with the intrusion of monzonitic to syenitic alkali feldspar porphyry stocks and dykes. These rocks intrude and alter Upper Cambrian-Middle Ordovician carbonate and shale units of the McKay Group, Middle-Upper Cambrian Jubilee and Middle Ordovician-Silurian Beaverfoot formations. Chalcopyrite is associated with quartz veining and silica flooding and is accompanied by up to 5 per cent disseminated pyrite. Copper-rich zones are geochemically anomalous in gold, arsenic, and mercury.

Locally, a 1 by 3 kilometre Cretaceous fine crystalline to porphyritic stock of quartz monzonite, monzonite, and minor syenite intrudes the Sheppard Formation (Purcell Supergroup) of mid-Proterozoic age, and the Jubilee Formation, McKay Group and Beaverfoot Formation of Cambrian and Ordovician age. Skarn and fracture-related copper-gold showings are present along the intrusion margin.

In 1984, Dome Exploration (Canada) Limited conducted a soil sampling survey and collected 88 rock samples in the Hot 1 showing area from feldspar porphyry intrusions and from skarn near the intrusions; these ran high in copper, up to 1,004 ppm (0.1 per cent copper) in sample 84CGR 39 (Assessment Report 12989). In 1985, Dome conducted a soil sampling survey on the Wild 1-4 claims (Assessment Report 14855).

In 1986, Dome Exploration Limited drilled 6 holes in the Hot 1 showing area. Values up to 275 parts per million copper were recorded from drilling. All holes intersected syenite, quartz diorite, skarn, or hornfels (Assessment Report 15906).

In 2007 Ruby Red Resources collected 364 soil and 72 rock samples about 1.5 kilometres (and more) to the northeast from the April showing (082GNW049), revealing new copper, lead, zinc, and silver mineralization (see Wild Horse, 082GNW116) (Assessment Report 29942). In 2008, Ruby Red completed work in the Hot 1 (082GNW050) showing area consisting of the collection of 445 soil samples (Assessment Report 30642). Work was conducted in the area of the new showings (see Do Drop, 082GNW146) previously found in 2007 and over the Hot 1 showing to southeast.

The showing has been explored as part of Dew Drop property in the Dewdney Trail Gold project of PJX Resources Inc. Exploration on the Property prior to its acquisition by the SG Spirit Gold Inc., and subsequent option to PJX in 2010 consisted of: prospecting; follow-up soil geochemistry; rock geochemistry; trenching, data compilation into GIS format; geological mapping and small drill program.

In 2016, PJX Resources Inc. conducted geological mapping and rock geochemistry sampling on the Dewdney Trail Property (Assessment Reports 36649).
