The Cob 1 is underlain by Pennsylvanian sedimentary rock of the Stikine Assemblage. The assemblage is intruded by Paleocene to Eocene granite and alkali feldspar granite of the Sloko-Hyder Plutonic Suite, in contact a few kilometres to the west, and granodiorite of the Early Jurassic Cone Mountain Plutonic Suite, in contact a few kilometres to the north and south.

Blebs and disseminations of pyrite and chalcopyrite occur within lenses of limonitic limestone. The area is dominated by weakly calcareous siltstone. The showing occurs within 75 metres to the north of a northeast trending fault.

CobPro01 is a soil grid target, located on the northern part of the Cob soil grid, that covers an area of 1.5 square kilometres. This prospective target is composed of clusters of pathfinder element anomalies including gold, silver, copper, lead, zinc, antimony and mercury anomalies which overlap well in a few concentrated centres observed along northeast trending faults. One of these soil anomalies contains sample Q923729 which assayed 1.18 grams per tonne gold, 5.9 grams per tonne silver and 0.03 per cent copper (Assessment Report 35895).

In 2013, IMGM International Mining Inc. staked the Phacops claims, totalling 163.48 square kilometres, located about 10 kilometres south of Telegraph Creek. In 2014, a 45-day field season resulted in the collection 103 silt samples and 110 rock samples mainly at the northern part of Phacops Property and included a cursory mapping of all 10 Phacops claims. Three prospective areas were defined, the Devils Elbow (104G 012), the Apex area (Cob) 104G 013), and the Phacops Mountain and Butterfly Mountain areas, on the southern part of the Phacops property.

In 2015, IMGM International Mining Inc. collected 591 soils over much of the Cob grid (Phacops property) which is 850 metres east-west by 4.3 kilometres north-south, totalling 3.66 square kilometres in area. They also collected 102 rock samples and 18 thin section samples. Mapping was completed on a 1:10,000 scale

In 2016, IMGM International Mining Inc. expanded the Cob grid/area 1-kilometre east along its entire north-south length. They collected 444 soils over an expanded Cob grid/area (Phacops property). They also collected 102 rock samples and 18 thin section samples. Mapping was completed on a 1:10,000 scale. Focus was on the V-3 zone (Dev 3 (104G 334) which yielded a number of mineralized samples in 2016 with high silver, copper, lead and zinc assays. In 2016, the 2015 Cob soil grid was expanded to the east at the most norther part of the grid. A number of exploration soil lines were also completed throughout the Cob area.
