The Diver Lake group is located immediately north of Diver Lake, approximately 275 kilometres northwest of Prince George. The Dag 1 claim covers a massive to banded massive sulphide showing on the Diver Lake logging road.

The area is underlain by Upper Triassic to Lower Jurassic volcanic and sedimentary rocks of the Sitlika Assemblage which have been regionally metamorphosed to greenschist facies. This assemblage is composed mainly of well foliated andesitic to rhyolitic pyroclastics and flows with lesser amounts of greywacke, siltstone and phyllite. The Sitlika volcanics are characterised by local development of sericite, quartz—sericite and chlorite schists. The Takla Fault separates the Sitlika rocks from the Tertiary Sustut Group to the west. The Permian Cache Creek rocks to the east are separated from the Sitlika by the Vital Fault and a serpentinite melange. The Cache Creek Group is bounded to the east by the Pinchi Fault and the Jurassic Hogem Batholith.

The sulphide showing is hosted by a series of intermediate to felsic pyroclastic rocks of the Upper Triassic to Lower Jurassic Sitlika Group.

In 1985, Noranda Explorations optioned the property from Art Halleran and performed a series of electromagnetic, magnetic, and geochemical surveys. The next year, a seven-hole diamond drilling program was completed for a total of 423 metres. Diamond drilling intersected numerous zones, 1 to 4 metres in size, of disseminated and stringer pyrrhotite and minor pyrite, up to 20 per cent locally, in brecciated rhyolites, andesites and dacites. No significant assays were returned.

In 1996, Angel Jade Mines Ltd. completed a soil and rock sampling program on the occurrence. A new outcrop was referred to in the report as the Vent showing, but no rock samples were taken. Anomalous values were observed in the soil samples.

In 1999, L.B. Warren conducted a soil sampling program over the area containing the occurrence. Results showed a large zinc, copper, and arsenic soil anomaly to the east and west of the Fall River access road on the property.

In 2006, Amarc Resources Ltd. completed multiple geochemical surveys over the property containing the occurrence. Anomalous levels of copper, lead, and zinc were detected.

In 2008, Amarc Resources Ltd. completed multiple geochemical surveys on the property containing the occurrence. Although no significant results were reported, Assessment Report 29729 details the anomalous zones detected.
