The Silver Sun occurrence is located in a steep south-facing gully on the north side of Notary (Silver) Creek, approximately 6.8 kilometres southeast of the junction of Lawyers Creek and the Toodoggone River.

The area lies within the Omineca-Cassiar Mountains at the southern end of the Toodoggone gold camp. The area is situated within a Mesozoic volcanic arc assemblage that lies along the eastern margin of the Intermontane Belt, a northwest-trending belt of Paleozoic to Neogene sediments, volcanics and intrusions bounded to the east by the Omineca Belt and to the west and southwest by the Sustut and Bowser basins.

Permian Asitka Group crystalline limestones are the oldest rocks exposed in the region. They are commonly in thrust contact with Upper Triassic Takla Group andesite flows and pyroclastic rocks. Takla volcanics have been intruded by Lower Jurassic granodiorite to quartz monzonite of the Black Lake Suite and are in turn unconformably overlain by or faulted against Lower Jurassic calc-alkaline volcanics of the Toodoggone Formation (Hazelton Group).

The dominant structures in the area are steeply dipping faults that define a prominent regional northwest structural fabric trending 140 to 170 degrees. In turn, high-angle, northeast-striking faults (approximately 060 degrees) appear to truncate and displace northwest-striking faults. Collectively these faults form a boundary for variably rotated and tilted blocks underlain by monoclinal strata.

The occurrence area is underlain by andesite crystal tuffs, volcaniclastic breccias and hypabyssal quartz trachyandesites, part of a larger package of Toodoggone Formation volcanics assigned to the Metsantan Member. Other lithologies of the Metsantan Member include mostly latite lava flows with interflow lahar, and a mix of epiclastic and pyroclastic rocks (Bulletin 86).

Locally, variably propylitic and phyllic-argillic–altered porphyritic andesite and/or lithic/crystal tuff host zones of silicification and quartz veining with associated gold values. Barite is also reported in the area.

In 1984, three rock samples (088, 222 and 224) yielded from 0.22 to 2.40 grams per tonne gold (Assessment Report 12911).
