The Arlington occurrence, consisting of nine Crown-granted claims and fractions, is located between Rest and Hooch Creeks, approximately 4.8 kilometres northwest of Salmo.

The area is underlain by argillites and argillaceous quartzites of the Lower to Middle Jurassic Hall Formation (Rossland Group), which are gently folded and intruded by a granite-porphyry sill of the Middle to Upper Jurassic Nelson Intrusions.

Locally, pyrite, galena, and sphalerite mineralization are hosted by quartz in a 0.6 metre thick vein that closely follows the granite- sediment contact but locally occurs as a footwall or hanging wall to the intrusive sill. The vein lies in strata that exhibits gentle "rolls" or folds down-dip and these structures may have had some controlling influence on mineralization. The vein has been explored and largely mined out for 460 metres along strike.

In 1975, a diamond drill hole (75-2) intercepted 2.13 metres yielding 3.7 grams per tonne gold (Property File - Shalmar Resources [1991-07-23]: GCNL Clippings - Clubine-Comstock and Arlington).

In 1982, there were an estimated 113 ,000 tonnes of dump material, from which samples assayed between 3 and 53.5 grams of gold per tonne (Northern Miner, October 28, 1982, page 6).

The mine was in production from 1900 to 1913 and again from 1932 to 1970. The total amount of ore mined during these years was 69,823 tonnes. Recovered from the ore were 1,700,339 grams of gold, 4,334,578 grams of silver, 520,420 kilograms of lead and 456,920 kilograms of zinc. In 1983, 3084 tonnes were mined producing approximately 7400 grams of gold. Development work totals greater than 5182 metres of drift, crosscuts and raises. The vein has been explored and largely mined out for 457 metres along the strike.

The Arlington claim (Lot 3648) was Crown granted to the Hastings (British Columbia) Exploration Syndicate Ltd. in 1899. The mine was in continuous operation from 1900 until June 1912; leases kept the mine operating until November 1913. No further work was done until 1927, when the Arlington Mining Company reopened the mine and installed a 15-stamp mill; the company operated intermittently through 1928. In 1929, the property was acquired by Relief-Arlington Mines Ltd.; the company was subsequently controlled by the W.N. O'Neil Company Ltd. and, in the 1940's, by Premier Cold Mining Company. The mine was operated under lease by R. Oscarson from 1932 to 1942. Messrs. Schrieves and R. & K. Golac optioned the property in 1943 and acquired title to it in 1945. Intermittent operations were carried out by the owners or by leasees until October 1948, when F.C. Buckland optioned the property. Subsequent operations were carried out under an agreement by Kenville Gold Mines Limited until May 31, 1950, when the property reverted to the former owners. New Arlington Mines Limited was formed in December 1951 to work the property. The mill capacity was increased from 50 to 125 tons per day and milling operations, mainly of dump material, continued into 1954. Subsequent operations were carried on intermittently by leasees.

In approximately 1961, the property was acquired by J. Russell of Borrega Springs, California. In 1969, G.D. Fox and Associates, of Trail, hauled material from the old dumps to the Trail smelter. These operations ceased in 1970. In 1975, Shalmar Resources completed a program of soil sampling, a VLF-EM survey and five diamond drill holes, totalling 368.4 metres, the area as the Rest 1-4 claims. In 1982, the property was owned by Chutine Resources Ltd. In 1983, a soil geochemistry survey was carried out. In 1985, Ryan Exploration Company Ltd. acquired Chutine's interest. Chutine dropped its option in 1988.
