The Adriana occurrence is located on McNab Creek, approximately 8.6 kilometres north-northwest of the creek mouth on Thornbrough Channel, Howe Sound.

The area is underlain by various phases of the Cenozoic-Mesozoic Coast Plutonic Complex and a small pendant of Lower Cretaceous Gambier Group metavolcanic and metasedimentary rocks. The intrusive rocks vary from quartz diorite with diorite inclusions, to granodiorite.

Mineralization consisting of pyrite, chalcopyrite, molybdenite and minor bornite hosted in the quartz diorite near its projected contact with granodiorite. The sulphides occur either on fracture plane surfaces or are associated with quartz veining. Minor sericite, epidote and chlorite are evident. Gambier Group rocks mask the eastward continuation of the mineralization.

In 1979, Tri-Con Mining, on behalf of Silverado Mines, completed a program of silt and soil sampling on the area as the Adriana 1-9 claims. Denarii Resources Inc. operated the property in 2010.
