The Revenge past producer is located 2.75 kilometres west- northwest of the summit of Mount Wallace and 1.75 kilometres east of Beaverdell, British Columbia (Assessment Report 16772).

Initial prospecting began in the Beaverdell area in the late 1880s. The first ore was shipped in 1896. The major producing mines in the Beaverdell silver-lead-zinc vein camp, from west to east, were the Wellington (082ESW072), Sally and Rob Roy (082ESW073), Beaver (082ESW040) and Bell (082ESW030), with numerous other small workings throughout the area.

In 1917, the Revenge, Sunset, Fraction and Bell Fraction were owned by G. Barrett. Work commenced on surface showings and included 7.6 metres of opencutting, 9.1 metres of stripping and 42.7 metres of drifting and crosscutting started from the lower opencut. Five tonnes of ore were reported mined from a 13-centimetre pay streak in these workings (Minister of Mines Annual Report 1917, page F203). Another 8 tonnes was reported sacked and ready to ship in the following year (Minister of Mines Annual Report 1918, page K220). Another 27 metres of drifting was done on a promising vein. The crosscut was continued for another 24 metres in 1919 with 24 tonnes mined and shipped. The crosscut was extended another 3 metres in 1921 and a 12-metre drift driven. The property was leased and bonded to Westbridge interests in 1922. Barrett, however, developed a new 31-metre upper tunnel. Development was continued by lessees in 1923, with another 23-metre tunnel driven 7.6 metres below the upper tunnel and a shallow shaft sunk in the upper tunnel. In 1925, the property was leased to R. Clothier et al., who did considerable development work. The following year, the Crysler Mining syndicate leased and bonded the Revenge, Sunset Fraction, and Bell Fraction claims. The Revenge No. 2 (upper) and lower tunnels were driven ahead with ore taken from the upper tunnel. Work ceased in 1927 as operating capital ran out. Further work in 1928 consisted of a short crosscut driven under the No. 2 tunnel by Barrett. The upper tunnel was mined for a short time in 1929 by Silver Star Mines Ltd. A minor amount of work was done in 1930. Work ceased until 1934 when a Penticton syndicate drove two crosscuts below and southwest of the No. 2 tunnel. The Revenge Mining Co. made the last recorded ore shipment in 1935. In 1939, the Revenge property was leased to R.C. McLanders and 61 metres of surface stripping and underground work was done. The following year, A.St. Clair Brindle carried out a small amount of development work. The property was acquired by Highland-Bell Ltd. in 1946, owner of the Beaverdell mine. In 1970, ownership was transferred to Teck Corp. The Beaverdell mine operated until 1991.

Granodiorite of the Westkettle batholith underlies most of the area. It has been intruded by small quartz monzonite porphyry stocks including the Beaverdell, Tuzo Creek, Eugene Creek and Carmi stocks. Other granitic porphyry stocks that intrude the Westkettle batholith are the Beaverdell porphyry. These have been dated by potassium- argon methods as Eocene (Watson, P.H. (1981): Genesis and zoning of silver-gold veins in the Beaverdell area, south-central British Columbia; Leary, G.M. (1970): Petrology and structure of the Tuzo Creek molybdenite prospect near Penticton, British Columbia and Exploration in British Columbia 1995, pages 124-126. The Westkettle batholith has been correlated with the Nelson intrusions that has been dated by potassium-argon and uranium-lead methods as Middle Jurassic. The Westkettle batholith contains remnants of pendants and/or screens of metamorphosed Wallace Formation. The Wallace Formation is believed to be correlative with the upper sections of the Carboniferous to Permian Anarchist Group. Lithologies include metamorphosed andesitic tuffs and lavas, hornblende diorite porphyries, olivine gabbro and hornblendite, hornfels and minor limestone. The contact between the Wallace Formation and the Westkettle batholith is sinuous, trending north with gentle east dips. These are unconformably overlain by Oligocene tuffs and conglomerates and Miocene plateau basalts. Westkettle granodiorite or Beaverdell quartz monzonite are the dominant hostrocks. Mineralization rarely extends into the Wallace Formation to the east.

A series of dikes, ranging in composition from quartz latite and quartz monzonite porphyries to hornblende andesite porphyries, are found throughout the area. In the Beaverdell camp, fine grained, brown andesite dikes, referred to as Wellington-type dikes, are believed to be pre-mineralization. One of these was dated by potassium-argon methods at 61.6 +/- 2.2 Ma (Watson, P.H., 1981). Quartz latite dikes are referred to as Idaho-type dikes and thought to be syn or post-mineralization. One of these has given a potassium-argon age of 50.6 +/- 1.5 Ma (Watson, P.H., 1981).

Beaverdell silver-rich veins are found in a 3.0 by 0.8 kilometre belt, referred to as the Beaverdell silver-lead-zinc vein camp. Five distinctly separate quartz vein systems are arranged roughly en echelon in this structural zone. The west-half contains the Wellington (Lot 2621), Sally (082ESW075, Lot 2092) and Rob Roy (Lot 2093, also part of Sally) systems which all strike east and dip from 70 degrees south to vertical. The Wellington and Sally each comprise two separate veins and the Rob Roy three. In the central part of the zone, the Bell (082ESW030, Lot 2343) comprises two veins which strike east to northeast and dip south to southeast. The eastern part of the zone contains the upper and lower sections of the Lass (082ESW133) and Highland Lass (Lot 2341, also part of the Bell) vein which strikes northeast and dips 50 degrees southeast. In general, quartz breccia veins and stockworks are so complex that continuous mineralized sections are a maximum of a few metres before being faulted or disrupted. Nevertheless, some mineralized zones have been found that extend up to 150 metres horizontally. Faults have been classified into five types based on their orientation, with each type having common orientation, kind of movement and age relationship: (1) high angle, north-striking normal faults, (2) low angle, north trending, strike-slip faults, (3) northeast striking, high angle normal faults (terminal faults), (4) northeast trending, 'slice' faults and (5) crossfaults. The northeast striking, high angle normal faults pose the greatest obstacle to systematic exploration and mining, as these faults are commonly spaced a few metres apart dividing veins into short segments in a northwest-downward direction.

Vein-type mineralization of the Beaverdell camp is characterized by a high silver content. Mineralization is composed of galena, sphalerite and pyrite with lesser amounts of arsenopyrite, tetrahedrite, pyrargyrite, chalcopyrite, polybasite, acanthite, native silver and pyrrhotite. The gangue minerals in veins are mainly quartz with lesser amounts of calcite, fluorite and sericite with rare barite. 'Ore ground' has been described as propylitic altered granodiorite, quartz diorite and quartz monzonite of the Westkettle batholith, up to 15 metres wide. These zones are characterized by sericite, clay minerals, chlorite, calcite, epidote and hematite. The fault-bounded veins commonly have a banded texture defined by outer, crudely parallel sulphide stringers. The wallrocks are brecciated and sheared over 30 to 150 centimetres width adjacent to veins. Weak sericite alteration of feldspars is pervasive in the Westkettle batholith.

The interpretation of galena lead-lead isotope age data coupled with geometrical and age relationships between dikes and veins suggests mineralization was formed around 50 Ma, coeval with Eocene stocks (Canadian Journal of Earth Sciences, Vol. 19, No. 6, pages 1264-1274, 1982).

The Revenge (Lot 3294s) adjoins the Beaverdell mine (082ESW030) in the southeast and the Sally mine (082ESW073) in the south. The property is underlain by Westkettle granodiorite. Quartz veins and veinlets averaging 15 centimetres in width occupy east trending shear zones and are displaced 30 to 60 centimetres by numerous faults. The shear zones are locally silicified.

Mineralization consists of sphalerite, galena and pyrite as nodules in a gangue of mainly quartz. A 13-centimetre pay streak was found in 1917. A sample taken in 1919 from the lower tunnel assayed 4.46 grams per tonne gold, 3504 grams per tonne silver and 5.8 per cent lead (Minister of Mines Annual Report 1919, page N169). The ore was also reported to carry high zinc. A sample from the upper tunnel taken in 1922 yielded trace gold, 5280 grams per tonne silver, 14 per cent lead and 5 per cent zinc (Minister of Mines Annual Report 1922, page N173). Sample 87-19, a 9-centimetre chip sample taken from the No. 2 tunnel in 1987 as part of ongoing property exploration, yielded 1836.3 grams per tonne silver and 1.02 grams per tonne gold (Assessment Report 16771).

The Revenge occurrence has produced 115 tonnes of ore intermittently between 1919 and 1935. A total of 564,053 grams of silver, 310 grams of gold, 5487 kilograms of lead and 3088 kilograms of zinc were recovered. Another 5.4 and 8 tonnes were reported mined in 1917 and 1918 respectively but no records could be found indicating shipment.
