The Hummingbird occurrence is located 9 kilometres southeast of Nelson. The vein (veins ?) was being worked as early as 1922. Minor production is recorded for the years 1933, 1941 and 1960. Numerous open cuts, pits and trenches are scattered over the property. The setting is similar to the Wisconsin property (082FSE036) to the east.

The area is underlain by granite and granodiorite of the Late to Middle Jurassic Nelson Intrusions (Nelson batholith) near the contact with Lower Jurassic Ymir Group sediments. Sediments comprise argillite, quartzite, siltstone and limestone. Plutonic rocks outcrop north, south and east of the main showings and numerous granitic sills intrude the sediments. Post-ore faulting is observed.

Erratic and discontinuous breccia and quartz veins, containing sphalerite, galena, pyrite, some pyrrhotite, arsenopyrite and chalcopyrite, cut grey black argillaceous quartzite. The veins trend east which is roughly bedding-parallel. The veins occur in a 2 metre wide fault zone in brecciated and silicified country rock. The country rock is locally replaced by sphalerite, galena and pyrite. Mineralization occurs in crosscutting fractures/veinlets in open space filling textures, in bedding parallel veinlets, in veins and in discontinuous blebs and lenses.

The main vein averages about 15 centimetres wide, but may be up to 45 centimetres, strikes about 080 degrees and dips 45 to 50 degrees south. A minimum length of 35 metres is suggested from the character of the mineralization.

A 0.35-metre chip sample across a 0.25-metre wide quartz vein exposed in an open cut above the portal of the main vein assayed 1.15 grams per tonne gold, 4.8 grams per tonne silver, 0.26 per cent lead and 0.005 per cent zinc (Assessment Report 14867).

In the years 1933 and 1941 minor production, totalling 77 tonnes, is recorded. The recovery was 1959 grams of gold, 4696 grams of silver, 1335 kilograms of lead and 5153 kilograms of zinc. Clean-up in 1960 produced 1711 grams of silver, 357 kilograms of lead and 973 kilograms of zinc from 20 tonnes of ore.
