The Moose-Climax occurrence is situated 0.5 kilometre east of the Kitsault River, 26.5 kilometres north of the town of Alice Arm. This vein has been extensively explored since 1916 for its silver-lead-zinc mineralization. The Moose showings are located between 609 and 762 metres elevation near the top of the steep Kitsault slope. A trail, now almost obliterated (ca. 1951), branches from the Trout Creek trail near the Silver Horde cabin and leads to the lowest working, about 535 metres to the north.

The area is underlain by a sequence of volcanics and sediments of the Upper Triassic Stuhini Group and the Lower-Upper Jurassic Hazelton Group. The sequence is folded into the doubly plunging, north-northwest trending Kitsault River syncline and has been regionally metamorphosed to greenschist facies.

The Moose-Climax prospect consists of a quartz-barite-carbonate breccia vein developed in a west dipping sequence of andesitic tuff and breccia of the Hazelton Group. The vein strikes east for 240 metres and dips steeply to the north. It has been traced downdip for 100 metres and varies in width from 1 to 3.7 metres. The vein has been segmented by a number of north to northeast-trending faults.

Mineralization consists of pyrite, marcasite, galena and tetrahedrite with traces of argentite and pyrargyrite in a gangue of colliform banded quartz, barite, carbonate, jasper and hematite.

Reserves initially defined for an 82 metre long, 46 metre deep, 2.6 metre wide block were estimated at 27,000 tonnes grading 309 grams per tonne silver (Assessment Report 6112, page 13). A later estimate of 90,000 tonnes grading 257 grams per tonne silver was calculated for a 200 metre long, 100 metre deep block with an average width of 2 metres (Assessment Report 9564, page 18).

Mineralization was discovered in 1916, and exploration was carried out by trenching and a drift adit. In 1920, Moose Group Mining Company Limited optioned the Moose property and drove a lower adit before dropping the option in 1921. The upper adit at about 716 metres elevation is reported to have been driven 30 metres along a mineralized zone but is inaccessible (ca. 1951), as is a shorter adit at 640 metres elevation. A lower adit driven 61 metres eastward at an elevation of 609 metres was accessible in 1951. The Climax showings are between 701 and 731 metres elevation on the east slope of the ridge between Trout Creek and Kitsault River and are reached by an old trail from the main Trout Creek trail; a cabin near the main trail is still standing (ca. 1951). Beginning in 1918, the Climax claims (Lots 941 and 942) were prospected by trenching. An adit was driven in 1925 and 1926, but since then little has been done and the trenches are partly sloughed. Little has been done since then. In 1964, Silver Butte Mines Ltd. completed 621.7 metres of diamond drilling.

During 2010 through 2019, Dolly Silver Corporation explored the area as apart of the Dolly Varden property. A complete property exploration history can be found at the Dolly Varden (MINFILE 103P 188) occurrence. In 2014, seven sample from the area are reported to have assayed over 20 grams per tonne silver and up to 250 grams per tonne silver including from a new zone of mineralization located approximately 400 metres to the west and 300 metres to the south (Higgs, A.A. (2015-05-01): Amended 2015 Technical Report for the Dolly Varden Property).
