The Mastodon zinc-lead-silver deposits, about 4 km east of the Copper Queen prospect, was discovered in 1898, and prospectors of the time probably knew of the malachite stained cliff at the Copper Queen. The first work on the Copper Queen was reported in the early 1900's, and sometime before 1965 three drill holes tested the showings, but no records of the results of this work were recorded.
In 1966, the S Group, consisting of 60 two-post claims, was staked for Clearwater Mines Ltd. of Bathurst, N.B. Clearwater used five diamond drill holes, totalling 1,425 feet, to test the occurrence. Holes CQ-1 and CQ-2 were collared on a bench approximately 300m to the east of the showings, but apparently failed to reach bedrock. Holes CQ-3, CQ-4, and CQ-5 were collared at an old drill site just above the main showings and fan drilled on a N20oW section line from a single setup. All three holes had intersections of copper and zinc mineralization over significant core lengths. Hole CQ-3 (a vertical hole) was reported to be well mineralized from 112ft to about 206ft, but only visual estimates of grade were reported (GCNL No. 114, June 14, 1966; Certificate of Work filed Feb. 7, 1967). Hole CQ-4 contained intersections from 170ft to 205ft and 225ft to 270ft averaging 0.6% Cu and 0.47% Cu, respectively (GCNL No. 131, July 8, 1966). Hole CQ-5 was reported to contain a 98ft section between 187-285' (true width reported to be 60ft) with grades running between 0.45% Cu and 1.14% Cu (GCNL No. 137, July 18, 1966). Grid drilling, reported to be planned by Clearwater, was never undertaken.
In 1976 Kerr Addison Mines Ltd. held the Property and conducted a program of soil and silt sampling and geological mapping which defined a northwest-southeast trending coincident copper, zinc and lead soil anomaly with a 600 metre length on the CC9 claim. The anomalous trend was open to the southeast. The Copper Queen showing was mapped as a 6 metre thick layer of calcareous metavolcanic rocks with malachite, sphalerite, chalcopyrite, and pyrite mineralization (Lund and Hajek, 1976). Kerr Addison drilled four BQ holes totaling 775.3 metres on units 13 and 14 of the CC9 claim, but specific locations and results were not reported (Exploration in B.C. 1977, pp. E66-E67).
Since the early 1980s major phases of advanced exploration work has been and is being done by mining companies on the J&L gold property which adjoins the eastern boundary of the Columbia Belle property. Proven and Probable Ore Reserves in the Main Zone are 1.7 million tonnes grading 7.4gpt gold, 75.9gpt silver, 4.4% zinc and 2.6% lead, and a further 1.9 million tonnes are classed as Possible Ore Reserves at a similar grade. Ore Reserves in the Yellow Jacket Zone are 690,000 tonnes grading 52.3gpt silver, 7.1% zinc and 2.5% lead, and a further 337,000 tonnes are classed as Possible Ore Reserves at a similar grade.
During the period July to October 1999 Orphan Boy Resources Inc. conducted an exploration program, consisting of 8.5km of flagged grid lines with 25m stations on lines spaced at 50m to 150m, collection and analyzing of 312 soil samples and 16 rock samples, limited geological mapping and prospecting, was conducted. Geochemical samples were analyzed for 36 elements by ICP and mass spectrometry techniques at Acme Analytical Laboratories Ltd. No work has been reported on the Property since 1999.
