The Two Mile Creek occurrence is situated on the west side of Two Mile Creek, approximately 400 metres south of the south end of Robinson Lake and 9 kilometres northeast of Hazelton.
The area is underlain by Middle Jurassic to Lower Cretaceous Bowser Lake Group clastic sedimentary rocks (mainly calcareous tuff and argillite). The Bowser Lake sequence is approximately 1500 metres thick and includes tuffaceous rocks, sandstone, greywacke, arkose, argillite, conglomerate and shale. Carbonaceous shales and thin coal seams occur at wide intervals throughout the succession. Localized intrusive stocks of the Bulkley and Babine intrusive suites occur throughout the Hazelton area. The strata strike north, dipping approximately 15 degrees west. Granodiorite of the Eocene Babine Intrusions intrudes the sedimentary rocks in the area.
A sulphide-bearing quartz vein occurs within massive arkose. Sulphide minerals include sphalerite, galena and arsenopyrite (Assessment Report 10457). The vein was exposed by a series of hand trenches; however, no record of the work exists. Examination of a dump pile revealed quartz with some arsenopyrite, galena and sphalerite.
The Two Mile Creek showing occurs on the American Boy property and has mainly been explored as part of work programs on the American Boy occurrence (MINFILE 093M 047) situated immediately east. The American Boy property was first staked in 1910. Between 1911 and 1916, Harris Mines Limited conducted surface trenching and underground development on five veins. From 1912 to 1915, small shipments of high-grade ore were sent to the smelter at Trail. In 1918, low-grade development ore was shipped to the Silver Standard gravity mill on Two Mile Creek.
In 1950, the property was acquired by American Standard Mines. Exploration work by the company consisted of stripping, diamond drilling and underground development. In the fall of 1951, a new high-grade vein, the No. 6 vein, was discovered. Further stripping of veins was conducted by Pioneer Gold Mines of B.C. Limited in 1952. Later, in 1955, J. Gallo shipped crude ore from a shoot on the No. 6 vein.
The property was restaked by George Braun in 1967. At this time, Northwest Midland Development Limited shipped 10.35 tonnes of Wifly Table concentrate from existing stockpiles. Minor trenching was completed in 1968 and 1971.
The property was restaked in 1976 by Tri-Con Mining Limited and then further expanded in 1981. In 1978 and 1980, Tri-Con carried out backhoe trenching, sampling and limited electromagnetic geophysical surveying. Exploration work in 1981 resulted in the rediscovery of the Two Mile Creek occurrence and the discovery of a new vein and mineralized float from a possible third vein at the American Boy showing. The Two Mile Creek vein had been exposed by a series of old pits of unknown age. Some unmineralized angular quartz float was found on the top of a knob just north of the Two Mile Creek showing.
In 1982, Can-Ex Resources Limited optioned the property. Between 1982 and 1984, Can-Ex Resources carried out a major exploration program consisting of geochemical and geophysical surveying, mapping, sampling, diamond drilling and trenching. Further programs conducted in 1986 consisted of soil sampling, very low-frequency electromagnetic surveying, backhoe trenching and diamond drilling. In 1987, exploration consisted of reconnaissance geological mapping, detailed soil geochemical sampling, electromagnetic geophysical surveying and trenching. The following year, three drillholes totalling 44.2 metres and 5 kilometres of very low-frequency electromagnetic and magnetometer geophysical surveying were completed.
The ground lay dormant until 2005, when Cadre Capital Incorporated staked new claims over the area. The following year, Golden Sabre Resources optioned the claims and carried out a limited exploration program of rock sampling and soil grid geochemistry.
By 2009, TAD Capital Corporation (later known as TAD Mineral Exploration Limited) had acquired a 94 per cent interest in the American Boy property. That year, Rio Minerals Limited conducted an exploration program of grid surveys, geochemical sampling, geophysical surveying, hand trenching and geological sampling and mapping on behalf of TAD Capital. In total, 280 metres of trenching were completed, and 423 soil and 23 rock samples were collected. Work occurred immediately east of the Two Mile Creek showing. In 2010, eight diamond drill holes totalling 704.24 metres were completed at the American Boy occurrence (MINFILE 093M 047).
By 2012, the Sidina property to the north had been expanded to include additional claims covering the Nine Mile Mountain area, including the American Boy property area.
