The Tiger vein occurs 0.4 kilometre east of the Kitsault River, 24 kilometres due north of the town of Alice Arm. This prospect has been extensively explored since 1916 for silver.

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

This prospect consists of a quartz vein developed in plagioclase porphyritic andesite and andesitic crystal vitric (shard) tuff of the Hazelton Group. These rocks have been silicified, carbonatized and pyritized in the vicinity of the vein. The vein has been segmented into four sections varying from 3 to 73 metres in length by a series of steeply dipping faults striking approximately 050 degrees. The vein has a total strike length of 110 metres and strikes between 000 and 020 degrees and dips steeply to the west. Widths vary from a metre to 5.7 metres. It has been traced downdip for at least 400 metres.

Mineralization consists of pyrite, marcasite, galena, pyrargyrite, argentite and native silver in a gangue of quartz. The northernmost 36.6 metres of the vein is reported to average 243 grams per tonne silver over an average width of 2.8 metres (Property File - Silver Butte Mines 1968 Annual Report, page 1).

Early work included opencuts and a crosscut adit below the original showing. In 1928, Utility Mines (Number One) Ltd. was incorporated to continue exploration work, which consisted of two adits below the original workings. Work was suspended in 1930 and the property remained dormant until optioned by Silver Butte Mines Ltd. in 1968. In 1969, Silver Butte constructed a camp near the lower workings and a horizontal AX-size hole 119 metres long was drilled.

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 2018, a drill hole (DV18083) on the Bonus zone, located approximately 250 metres to the west- south west, yielded 161.4 grams per tonne silver over 15.50 metres (7.75 metres true width) (Turner, A.J. (2019-05-08): Technical Report and Mineral Resource Update for the Dolly Varden Property).
