The Orion occurrence is located at an elevation of approximately 1870 metres on a east-southeast trending ridge, west of Kemess Creek and approximately 2 kilometres north-northeast of Kemess Lake, about 188 kilometres north-northwest of the community of Germansen Landing.

The Toodoggone district lies within the eastern margin of the Intermontane Belt and is underlain by a northwest-trending belt of Paleozoic to Paleogene sediments, volcanics and intrusions covering an area of 90 by 25 kilometres. The basement rocks are Proterozoic metasedimentary equivalents of the Hadrynian Ingenika Group. These rocks are unconformably overlain by volcanic and sedimentary units of the Devonian to Permian Asitka Group, which are in turn overlain by Upper Triassic basaltic to andesitic flows, volcaniclastics and minor limestone of the Stuhini Group. Volcaniclastic rocks of the Lower Jurassic Hazelton Group and rhyolitic to dacitic flows, intrusions and volcaniclastics of the Lower Jurassic Toodoggone Formation (Hazelton Group) overlie the Stuhini Group. Further to the west, nonmarine sediments of the Cretaceous Sustut Group overlie the volcanic strata and form the western margin of the district.

The Early Jurassic Black Lake Suite, of quartz monzonitic to granodioritic composition, has intruded the older strata in the central and eastern parts of the region and forms the eastern margin of the Toodoggone district. Within the district, syenomonzonitic and quartz feldspar porphyritic dikes may be feeders to the Toodoggone Formation.

The dominant structures in the area are steeply dipping faults that define a prominent regional northwest structural fabric trending 140 to 170 degrees. 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.

At the Orion showing, at surface, a series of 1- to 50-centimetre- wide vuggy quartz veins host copper mineralization, whereas diamond drilling intersected pyritic and silicified sediments adjacent to a biotite feldspar porphyry intrusive with gold values and variably chlorite- and epidote-altered basalts hosting pyrite, chalcopyrite, arsenopyrite and sphalerite.

In 2015, a diamond-drill hole (KH-15-25) yielded intercepts of 24.10 grams per tonne gold over 1.60 metres of silicified sediments with pyrite; 50.7 grams per tonne silver with 0.101 per cent zinc over 2.0 metres of chloritic basalt with pyrite and arsenopyrite; and 0.227 gram per tonne gold, 15.70 gram per tonne silver and 0.504 per cent copper over 2.0 metres of epidote-altered basalt hosting pyrite and chalcopyrite (Assessment Report 36283).

The area has been historically explored in conjunction with the nearby Kemess North deposit (094E 021) located 3.6 kilometres north-northwest, and the Kemess South deposit (094E 094) located 3.6 kilometres south-southwest.

During 1966 through 1971, Kennco Explorations Ltd. completed programs of geochemical sampling and geological mapping on the area immediately west as the Kemess 1-100 claims.

In 1975 and 1976, Getty Mines Ltd. examined the property and completed programs of soil sampling and geological mapping on the area immediately west.

During 1986 through 1989, El Condor Resources Ltd. completed programs of rock and soil sampling, geological mapping, trenching and a 14.1 line kilometre ground magnetic survey on the area immediately west as the New Kemess 1-2 claims.

In 1990 and 1991, El Condor Resources Ltd. conducted programs of geological mapping, geochemical sampling and a 201.0 line kilometre induced polarization survey on the area as part of the Kemess property. In 1999, Royal Oak Mines Inc. completed a series of 16.0 line kilometre long ground geophysical surveys on the area.

During 2000 through 2011, Northgate Minerals Corporation examined the area as part of the Kemess property. In 2003, seven diamond-drill holes were completed on the area.

During 2013 through 2017, AuRico Gold Inc. completed programs of geological mapping and diamond drilling on the area as part of the Kemess East property. In 2015, five diamond-drill holes were completed in the Ron 9 (Orion) area.
