The Butcher Boy past producer is located immediately south of Carmi, British Columbia, on the Butcher Boy (Lot 2352) Reverted Crown grant. The Reverted Crown grant lies on the west side of the West Kettle River and adjoins the Carmi property (082ESW029) to the west.

The Butcher Boy claim was first staked in 1896 by J.C. Dale. Development work initially consisted of trenches. Shaft sinking began in 1903. In 1904, the Butcher Boy (Lot 2353), May (Lot 2355) and No. 3 (Lot 2354) were Crown granted to J.C. Dale, R.D. Kerr and P.B.S. Stanhope. In 1913, the claims were leased to A. Robinson from F.J. Finnucane. No further work was reported until 1930 when Dale, Stanhope and Kerr leased the property to J. Carlson and associates. The underground workings were extended with ore shipments made in 1930 and 1931. Canadian-American Mines Ltd. acquired the Carmi (082ESW029), Butcher Boy and 18 other claims in 1932. In 1934, the underground workings of the Carmi mine were extended into the Butcher Boy claim 94 metres. Canadian-American Mines Ltd. assets were taken over by Carmi Gold Mines Ltd. in 1934 and further underground development work was completed. Lessees worked the property for a short time in 1935. The claim was acquired by J.V. Hinks and J.A. Olinger. Options have been held by International Minerals and Chemical Corp. (Canada) Ltd. in 1970 and by Husky Oil and G.V. Lloyd Exploration Ltd. in 1970 and 1971. Vestor Explorations Ltd. optioned Mineral Lease M 290, which include the St. Lawrence (Lot 1562s), Copper Queen (Lot 1563s), Lily (Lot 1565s), Butcher Boy (Lot 2353), No. 3 (Lot 2354), May (Lot 2355), No. 6 Fraction (Lot 2356) and Hatford (Lot 2358) Reverted Crown grants, Mineral Lease ML 425 and about 300 adjacent claims, in 1974. In 1981, Kelvin Energy Ltd. was owner of the Carmi claims, surrounding the Carmi occurrence. An 8-hole diamond drill program was conducted, three of which tested for the Carmi veins below the old workings.

The Butcher Boy is hosted by granodiorite of the Jurassic Westkettle batholith and an irregular body of Permian Wallace Formation approximately 2.56 square kilometres. The Westkettle batholith varies in composition from granodiorite to quartz diorite to diorite. The granodiorite phase is medium grained, grey to pink with chlorite or occasionally biotite-altered mafics. Local epidote and minor potassic alteration also occur. The quartz diorite phase is commonly foliated and porphyritic. These phases are intruded by quartz monzonite, quartz-k-feldspar and andesitic dikes. Veins are composed of quartz, quartz and k-feldspar or quartz-calcite plus or minus pyrite. The veins are commonly associated with a clay-rich fault gouge.

The Butcher Boy and Carmi workings appear to be on the same faulted vein, following a shear zone in fine-grained granodiorite. The shear zone strikes 090 degrees and dips 45 to 60 degrees southward. It has been traced for over 549 metres strike length, despite minor fault displacement. The vein varies from 5 to 213 centimetres width. One mineralized ore shoots near the surface was reported to be 76.2 metres long.

Mineralization consists of pyrite with lesser sphalerite and galena carrying gold and silver values. Minor chalcopyrite and molybdenite are also present. The gangue is quartz and ankerite and in places intensely sericitized andesitic dike.

A general sample of unsorted ore taken in 1930 from the shaft dump yielded 11.66 grams per tonne gold, 85.71 grams per tonne silver and 1.6 per cent lead (Minister of Mines Annual Report 1930, page 220). In the following year shipped ore averaged 17.14 grams per tonne gold, 102.86 grams per tonne silver and 3 per cent zinc (Minister of Mines Annual Report 1931, page A126).

The Butcher Boy has produced 2000 tonnes of ore intermittently between 1904 and 1940. Recovery included 21,337 grams of silver, 5195 grams of gold, 361 kilograms of lead and 634 kilograms of zinc.
