The Excelsior showing is located on the right bank of Monashee Creek, previously known as the south fork of Cherry Creek, about 32 kilometres southeast of Lumby.
A tunnel was sunk 2.4 to 3 metres in 1901. No other reference has been found for this showing.
The area is underlain by sedimentary and volcanic rocks of the Upper Triassic to Lower Jurassic Nicola Group. These comprise basic lavas, pyroclastics, argillites and some limestones.
A quartz vein about 20 centimetres wide contains argentiferous galena. The vein was found on surface and the tunnel attempted to follow it. Samples reportedly assayed 4113.6 grams per tonne silver (Minister of Mines Annual Report 1901, page 1127).
