The Bollinger occurrence is located 1.25 kilometres northeast of the Highland Surprise (082KSW037), some 29 kilometres northwest of Kaslo, British Columbia.

The main lithologies of the area are assigned to the Permian Kaslo Group, consisting of andesite flows, pyroclastics and tuffaceous sediments. The volcanics and sediments are generally oriented 320 degrees and the contact between these two units has a strike of 350 degrees. Serpentinite is the most extensive rock type exposed in this area, forming northwesterly trending bands with steep southwest dips and extending up to 750 metres in width. Talc and asbestos are common alteration minerals associated with this serpentinite unit. The contact between the serpentinite and surrounding lithologies is faulted. This faulted contact has a strike of 350 degrees and a steep westerly dip. The surface trace of this fault can be traced for several kilometres. Underground, this fault is marked by a heavy talc gouge. Dikes and sills in the area are dioritic and feldspar porphyry. For a more detailed geological description of the area the reader is referred to the Highland Surprise occurrence.

Quartz veins are common throughout the property. The Bollinger showing is reported to consist of gold, copper and lead mineralization in a quartz vein (Minister of Mines Annual Report 1901 and Geological Survey of Canada Open File 464). No other specific geological information could be located for this mineral occurrence.
