The Hot Bath area is underlain by the contact of late Triassic quartz monzonite and Middle Jurassic monzodiorite to gabbro of the Three Sisters Plutonic Suite.

In 2011, Finsbury Exploration Ltd carried out exploration over the Property as part of a soil and silt sampling program over a much larger 168,983 hectare property area known as the Galaxie property.

In 2012, Quartz Mountain Resources Ltd, on the Galaxie property, conducted systematic soil and IP surveys over eight high-priority grids and two target areas identified by the 2011 stream sediment and soil geochemical results. This work included an IP survey over almost the entirety of title 512878 and the southeastern third of title 604847.

In 2014, three rock samples were taken from foliated gossanous quartz monzonite at UTM coordinates 446592 east and 6447748 north. One of these rock samples assayed 3 per cent copper and 3 grams per tonne gold ( Assessment Report 35456).

The 2015, Induced Polarization geophysical program detected chargeability and resistivity anomalies coincident with the high MMI values in the Hot Bath area. MMI soil sampling yielded copper values up to 42,900 parts per billion with the mean value being 1165 parts per billion, indicating a strong copper anomaly on the south flank of an interpreted intrusive. Some 250 metres west of this MMI anomaly 4 rock samples were collected with one sample (2510), taken from an exposed, oxidized quartz vein with abundant pyrite and chalcopyrite, assaying 3.39 per cent copper, 2.9 grams per tonne silver and 0.0284 gram per tonne gold (Assessment Report 36409).

WORK HISTORY

The Hot Bath property was acquired by DeCoors in 2014, based on results from an airborne magnetic geophysical survey, rock geochemistry surveys and geological mapping completed as part of Geoscience B.C.'s Quest Northwest study.

In 2014 samples were collected for a total of 56 soil samples 43 using MMI technique and analysis and 13 standard soil with ICP analysis and 4 rock samples described in Assessment Report 35456.

Exploration work by DeCoors in 2015 and 2016, included 760 MMI (mobile metal ion) geochemical samples, 12-line kilometres of induced polarization and 3.5-line kilometres of magnetometer geophysical data. These data identified an extensive area, 800 metres by one kilometre of coincident high-chargeability geophysical values and anomalous MMI copper, and other indicator minerals in soils.

In 2017, Gray Rock Resources Ltd entered into an agreement with DeCoors Mining Corp to acquire the Hot Bath property.
