The New York showing is located about 1150 metres south of the Stewart highway and approximately 5 kilometres east-northeast of the confluence of American Creek with the Bear River.

The area is underlain by Hazelton Group rocks comprising the Lower Jurassic Unuk River Formation. These rocks consist predominantly of subhorizontal to gently north dipping andesitic flows and pyroclastics. A prominent reddish brown weathering argillite/tuff unit occurs in the extreme southeastern corner of the New York claim (Lot 1485). It can be traced east through the London (Lot 1480), Kensington Fr. (Lot 1484) and Elgin (Lot 1481) claims and is probably the same unit that hosts the George Gold-Copper Lower showing (104A 029). Similarly, it can be traced to the southwest, and then southeast through the Grey Copper claims (104A 066).

Mineralization occurs mainly in sheared andesitic rocks, immediately below(?) the argillite/tuff unit. Alteration minerals include chlorite, actinolite and epidote. The altered rocks contain up to 50 per cent pyrrhotite and pyrite with minor chalcopyrite over a 5 to 10 metre thickness. Grab samples from the showing assayed from 0.05 to 0.57 per cent copper, 2.7 to 3.4 grams per tonne silver and trace to 0.2 gram per tonne gold (Assessment Report 7201).

Exploration work in 1996 on the New York claims further defined the “iron formation” which was found generally to consist of a bed of chloritic-argillic andesite mudstone which has been mineralized with pyrite, pyrrhotite and occasional chalcopyrite, sphalerite and galena. This massive sulphide horizon remains relatively near surface from the New York adit approximately 100 metres upslope to the south and several hundred hundred metres to the east. Anomalous gold values occur with increased concentrations of chalcopyrite or other metal sulphides. Sampling and drilling in this area indicates that this shallow dipping horizon has been mineralized with up to 10 metres of pyrrhotite and pyrite with occasional chalcopyrite, sphalerite and anomalous gold. The best result in the drilling was hole 7 which intersected 6.4 metres grading 0.15 per cent copper and 0.27 gram per tonne gold (Assessment Report 24752).

The New York and London claims were held by Erickson and McNeill in 1908. The Bear River Mining Co. Limited was formed to explore the property and, in 1910, held eight claims in the area, including the New York and London. Work reported in 1910 comprised a 32 metre long tunnel and several opencuts. The claims were Crown granted to the company in 1913. In 1929, Atlas Gold Copper Mining Company carried out drilling on the nearby Bear Valley claim; the drilling was designed to test the extension of the George Gold-Copper Lower (104A 029) zone on the Elgin claim, immediately east of the London claim. Drilling failed to intersect anything of significance. Some drilling may have also been done near the workings on the New York claim; results are not available. In 1955, New Rufus-Argenta Mines Limited acquired the New York-London property and reported a limited amount of work in 1956 and 1964. In 1966, the company name was changed to Crest Ventures Limited. That year a subsidiary, Crest Copper Company Ltd., was incorporated and took over the property. In 1967, Cominco optioned the property and carried out geological mapping, a magnetometer survey and drilling (11 holes totalling 117 metres); the option was subsequently dropped. In 1971, Keith Copper Mines Ltd. performed a magnetometer survey, trenching and drilling (4 holes totalling 244 metres) on part of the property and adjacent Mina claim group; no work was reported on the showing. In 1978, Tournigan Mining Explorations Ltd. acquired the New York-London property of five claims and carried out geological mapping and trenching. In 1984, Tournigan conducted further geological work on the property. In 1994, Westmin Resources Ltd. optioned the New York claims and performed a magnetometer survey, a soil sampling survey, reconnaissance geological mapping, lithogeochemical sampling, hip chain and compass grid surveying and an airborne geophysical survey. In 1996, exploration work conducted on behalf of Transworld Trading Corporation on their Bear property consisted of 170 chip samples taken from various showings and 76 samples were split from the 1362 metres of BTW core drilling.
