The Hummingbird (Lot 1369) occurrence is located immediately west of the Granby River at the Hummingbird Bridge of the North Fork (Granby) road.

The area is underlain by grey and white limestone of the Triassic Brooklyn Formation, which is intruded by small diorite dikes and bounded to the north by granodiorite of the Cretaceous Anstey pluton and to the south by greenstone.

The limestone is replaced by silica along fractures that carry pyrite, pyrrhotite, marcasite, sphalerite, arsenopyrite, galena and minor chalcopyrite in stringers and as isolated segregations along bedding planes. To the north, sediments have been intruded by a dark, fine-grained diabase dike. Sulphides occur in vein-fissures in limestone and at the contact with andesite.

Locally, two mineralized zones have been identified, the first located near the southeast corner of the Humming Bird and Humming Bird Fraction claims and the other along the boundary of the Humming Bird Fraction and OK claims, approximately 300 metres to the north-northwest.

In 1974, two samples (HB 1 and 2) yielded 13.0 and 30.1 grams per tonne gold, 88.9 and 75.2 grams per tonne silver with 8.00 and 1.80 per cent zinc, respectively (Property File - Bianca Resources Ltd. [1977-10-11]: Prospectus Report - Humming Bird Mineral Claims - Bianca Resources Ltd.).

In 1991, a sample of a 20-centimetre wide facture or shear situated in marble adjacent to diorite and hosting pyrite yielded 66.24 grams per tonne gold (Property File - Orvana Resources [1991-11-01]: OK Syndicate - Interim Report).

A total of 942 tonnes of ore was mined from the Hummingbird, from which 52 501 grams of silver, 23 575 grams of gold, 37 802 kilograms of zinc, 254 kilograms of copper and 82 kilograms of lead were recovered.

Some work was reported to have been done on the Hummingbird in 1897. The property was owned by the Humming Bird Gold Mines, Ltd. in 1899 and approximately 47 metres of underground development had been done. The orebody, which consisted of pyrrhotite and chalcopyrite, was reported to be 1.2 metres across on surface, dipping into the hill at a flat angle. The Hummingbird was Crown-granted in 1900 and in that year 60 metres of tunneling was reported; however, that might be the overall total at that time. In 1901, the mine was leased to Misters Shannon and Layeux, who were shipping ore. A total of 150 metres of tunnelling had been done. In 1900, 1901 and 1903, a total of 546 tonnes of ore was mined with only silver and gold being recovered.

The Hummingbird was again active in 1916, shipping 57 tonnes of ore, this time with some copper recovered as well as gold and silver. The workings were dewatered in 1925, but no additional development was reported at the time. The ore was reported to be pyrite and marcasite. In 1926, the Hummingbird and Hummingbird Fraction were Crown granted to Carl Anderson. In 1929, the Hummingbird Fraction and Mammie were operated by Carl Andersen. It was reported at the time that numerous opencuts and a short tunnel had been driven on a zinc-pyrite mineral zone in the limestone, approximately 30 metres above the old workings. The ore was reported to occur in beds conforming to the dip of the limestone and vary in width from 5 to 25 centimetres. Samples varied from “$10 to $20 in gold to the ton”. Carl Anderson shipped ore in 1939 and over the next four years, until 1943, a total of 339 tonnes was produced with values in silver, gold and zinc. It was reported that 15 metres of drifting was done in 1942. Another shipment of 41 tonnes is documented for 1950.

In 1975, Chang and Riepe collected 109 soil samples and conducted 6 kilometres of VLF and 2 kilometres of ground magnetics surveying on the Hummingbird. In 1977, Bianca Resources Limited conducted a 6-kilometre ground scintillometer survey. In 1978, Bianca drilled three EXT holes, totalling 183.2 metres, on the Humming Bird.

The property was worked in 1981 and again in 1985 by Minequest Exploration Associates Ltd., who held the Hummingbird as part of a larger property that they conducted work on. Most of the work was apparently directed toward the Seattle claim (MINFILE 082ESE158). During 1991 through 1994, the claims were held by Orvana Minerals Corp., also as part of much larger land position in the area. Much of the work by Orvana was directed elsewhere besides the Hummingbird. See Seattle (MINFILE 082ESE158) and Sailor Boy (MINFILE 082ESE077) for further details of the area history.
