The Aspen occurrence is located on a north facing slope, south of the Nechako Reservoir, approximately 6 kilometres southwest of the mouth of Chedakuz Creek.

Regionally, the area is underlain by undivided volcanic rocks of the Middle Jurassic Naglico Formation (Hazelton Group) which have been intruded Eocene gabbroic to dioritic rocks.

The area is underlain by a variety of igneous rocks that include a bimodal suite of volcanic flows as well as coarser-grained bodies that are believed to represent sub-volcanic intrusions emplaced at shallow depth. In addition, there are massive to weakly bedded ash and lapilli tuffs as well as lesser quantities of tuff breccia with heterolithic clasts exceeding one metre in diameter. The sub-volcanic intrusives range from narrow dikes to larger bodies that are several hundreds of metres in diameter. They range compositionally from highly leucocratic rhyolite, often containing large quartz phenocrysts, to more mafic, andesitic rocks.

Locally, massive, silicified rhyolite that contains up to 4 per cent pyrite which is fine to coarse grained and disseminated. It is often associated with abundant jasper veining and contains vugs lined with small euhedral quartz crystals. In very rare instances, magnetite is present. This style is believed to be associated with an intrusive dome.

In 2017, a sample (2948130) of jasper-magnetite-bearing rock assayed 29.4 grams per tonne silver and 0.14 per cent zinc (Webster, I., Ray, G.E. (2018-01-17): Technical Report - The Aspen Project).

Another zone of possible mineralization, referred to as the Bruin zone is located to the north east, comprises veins up to 5 centimeters thick containing coarse grained pyrite and black sphalerite with very trace amounts of arsenopyrite. The Bruin zone mineralization has only been seen in roadside float. The mineralized float includes both highly altered mudstone-siltstone as well as some bleached and strongly altered igneous rocks of unknown composition.

In 2017, samples of mineralized mudstone float assayed up to 0.23 gram per tonne gold, 9.4 grams per tonne silver and greater than 1 per cent zinc (Webster, I., Ray, G.E. (2018-01-17): Technical Report - The Aspen Project).

Limited exploration during the early 1980’s on the area, is reported to have identified mineralization in outcrop containing up to 30.1 grams per tonne silver and 0.16 per cent zinc (Webster, I., Ray, G.E. (2018-01-17): Technical Report - The Aspen Project).

In 2017, J. Bond Capital Corp. completed a program of geological mapping, prospecting and geochemical sampling on the area as the Aspen property.
