The Upper Osprey occurrence is located south of End Lake and the Osilinka River, about 41 kilometres north of the community of Germansen Landing.

At the showing, primary and secondary dolomite breccias of the Ordovician to Lower Devonian Echo Lake Group have been highly metamorphosed by veining and replacement. A large gossanous zone, at least 10 by 20 metres in area, contains several zones of massive sulphide, each exposed over areas of 10 by 5 metres and greater. Sulphides include pyrite, chalcopyrite and sphalerite, plus/minus galena and bornite. A second showing, less than 100 metres away, occurs in a quartz latite intrusion and is pipe-like in shape and about 8 metres across. Mineralization consists of pyrite plus/minus chalcopyrite and malachite.

In 2017, work was conducted on the Wasi Davies property claims which cover the Upper Osprey showing (this description) and the Osprey showing (094C 129) located 1.1 kilometres northwest. The exploration work by B. Kreft consisted of prospecting and geochemical sampling (54 soil samples and 15 rock samples).
