The Queen Mary occurrence is located at about 480 metres elevation northeast of Reed Creek, in the historic Fairview mining camp. The Stemwinder occurrence (082ESW007) lies 1 kilometre to the northeast. Oliver, British Columbia lies 6 kilometres to the east.

The Queen Mary occurrence lies within the Okanagan Terrane of the Intermontane tectonic belt. The area is predominantly underlain by polydeformed and regionally metamorphosed rocks of the Carboniferous to Permian Kobau Group. Highly deformed, low-grade metamorphic quartzite, phyllite, schist, greenstone and marble comprise the main units of a 1900-metre structure succession. Three phases of fold have been identified in the Kobau Group rocks. The initial phase of folding was coincident with pre-Jurassic regional metamorphism, whereas later phases of folding are related to intrusive activity. The main intrusions in the Fairview camp are the Jurassic Oliver plutonic complex and the Jurassic to Cretaceous Fairview granodiorite. The Oliver pluton is heterogeneous and is composed of biotite hornblende granite, porphyritic biotite granite, garnet muscovite granite, porphyritic quartz monzonite and syenite. Other intrusive phases cutting the Kobau Group metasediments and volcanics include aplite dikes, granitic, dioritic and mafic stocks, auriferous quartz veins related to Jurassic intrusions and Tertiary northeast-trending mafic dikes.

The Queen Mary occurrence is hosted by siliceous schist, chlorite-actinolite phyllite and foliated phyllitic quartzite of the Kobau Group, near the contact with granodiorite of the Fairview pluton. In places, the vein lies between porphyritic dikes and schists.

No information could be found describing type and character of mineralization at the Queen Mary occurrence. However, quartz veins are ubiquitous in metasedimentary rocks of the Kobau Group, displaying varying degrees of deformation related to their time of emplacement. At the nearby Joe Dandy occurrence (082ESW161), mineralization is hosted within a 30 centimetre to 1.0 metre wide bluish white quartz vein, striking 115 degrees and dipping 36 to 60 degrees north. The vein is reported to be traceable on surface over 457 metres. Minerals in the vein include pyrite and galena. Areas where high sulphide mineralization occurs reportedly contains good gold values.

In 1940, the Queen Mary was owned and operated by A. Whitehead and produced 73 tonnes of ore from which 1244 grams of silver and 715 grams of gold were recovered.

In 2014 and 2019, Hi Ho Silver Resources Inc. completed minor programs of rock sampling and structural analysis on the area as the Fairview property.
