Work History

The Copper King deposit was discovered in 1897 and first staked in Jul/98 by Jack McIntyre. By 1900, most of the important deposits which form the Whitehorse Copper Belt had been discovered and staked (Dobrowolsky and Ingram (1993), p. 3) and the first small ore shipment was made that year. Mining continued at intervals for the next 20 years at seven different mines - Copper King, Carlisle, Pueblo, Valerie, Grafter, Arctic Chief and War Eagle - and some 14 7330 tonnes of cobbed ore were shipped at an average grade of about 4% copper, mostly from the Pueblo Mine in 1912-17, prior to a disastrous cave-in. Companies involved in this early work included Whitehorse Copper Company Ltd, Yukon Copper Company Ltd, British American Corporation Ltd, Yukon Pueblo Mining Company Ltd, Arctic Chief Copper Mines Company Ltd, Grafter Copper Mining Company Ltd and Atlas Mining Company Ltd. Between 1924 and 1929, Richmond Yukon Company Ltd and Richmond Consolidated Mining Company Ltd drilled 20 holes at the Pueblo deposit, worked underground on the Carlisle and shipped about 900 tonnes.

In 1947 Noranda Mines Ltd conducted linecutting, geophysical surveys and in 1948 drilled 2 holes in the Pueblo deposit, 3 holes (302 m) between the Verona and Arctic Chief deposits, 5 holes (435 m) in the Keewenaw deposit and 7 holes (471 m) in the Big Chief deposit. Yukon Mining Company Ltd conducted bulldozer trenching in 1952 at the Grafter and Valerie properties. In 1953, Hudson Bay Mining & Smelting drilled 10 holes (682 m) on the Cowley Creek deposit, optioned from J.A. Smith, J.A. Hanna and Per Johnson. This showing was later restaked as the Sue cl (75653) by D.J. MacIssac, who bulldozer trenched in 1961-62. Imperial Mines & Metals Ltd was formed in Sep/54 and began acquiring claims on the Copper Belt. In 1956, it conducted magnetometer surveys and drilled two properties. The name was changed in Mar/57 to New Imperial Mines Ltd and, by 1963 the company had acquired by staking, option or purchase, all the properties on the Copper Belt (including the Pueblo from Beadak Mines Ltd except the Spring Creek and Polar (see G.S.C. Paper 63-41).

Accelerated exploration from 1963 to 1965 outlined 5.0 million tonnes of open pit reserves in six separate deposits grading 1.2% Cu and a feasibility report in Nov/65 recommended an 1 800 tonne mill. Sumitomo Metal Mining Company Ltd provided senior financing for milling, which commenced in March/67. Additional financing to develop deep ore found in 1965 beneath the Little Chief pit was provided in Oct/69 by Hudson Bay Mining & Anglo American Corporation of Canada Ltd, which also entered a joint venture with the company in Aug/72, when it changed its name to Whitehorse Copper Mines Ltd, for exploration of the north half of the property.

Modern fringe staking by companies which did no significant work or which does not cover known showings (all in sheet 105D/11) include Ajax cl (98649) in Feb/66 by Ambassador Mining Developments Ltd; Joe cl (23667) in Feb/68 by Giltana Copper Corp Ltd; At cl (Y11916) in Feb/67 by Cree Lake Mining Ltd; and Tag cl (Y23331) in Jan/68 by Canzac Mines Ltd. Whitehorse Copper conducted substantial exploration between 1973 and 1982, including 188 holes (35 480 m) in the Little Chief, Cowley Park, Black Cub, War Eagle, Valerie, North Star, Arctic Chief, Pueblo, Empress of India, and Black Cub South deposits, a 4 500 tonne bulk sample from the Cowley Park South Zone, and IP, gravity and EM surveys. Holes were drilled as deep as 991 m.

Between Mar/67 and the end of 1982, Whitehorse Copper mined 10 247 936 tonnes of ore. Of this, 2 851 870 tonnes grading 1.06% Cu were mined from several open pits prior to Jun/71 and the remainder, 7 396 116 tonnes grading 1.50% Cu, from underground in the Little Chief deposit. Precious metal content averaged about 0.7 g/t Au and 13.0 g/t Ag. Total production, some 70% of which came from the Little Chief, was 123 145 041 kg Cu, 7062.4 kg Au and 85 577 kg Ag. The combined size of the open pit and underground portion of the Little Chief deposit totaled about 7.25 million tonnes averaging 1.5% Cu.

After the mine closed, 3 holes (1171 m) were drilled at the Cowley Park, Black Cub, War Eagle & Best Chance deposits and near Rabbit's Foot Canyon, mainly exploring for gold-rich skarns. Part of the property was optioned in 1989 to Aurora Gold Ltd which performed linecutting and in 1990 drilled seven reverse circulation holes totaling 500 m and a mag and VLF survey in 1991. Other claims were allowed to lapse.

In 1990, W.B. Wallis restaked the Rabbit's Foot showing as Fox cl 1-16 (YB27111) and trenched in two areas east and west of the shafts. B. Scott staked Carl cl 1-4 (YB27182), Railway cl 1-4 (YB27186), and Big Four cl 1-2 (YB27190) in the Keewenaw-Black Cub area. R. Stack prospected on the Polar group. H. Larsen performed blast trenching in the Arctic Chief area in 1990 and 1991. H. Coyne restaked an area south of Arctic Chief as Thule cl 1-4 (YB35746) in Mar/91.

Between Jan and Mar/94 B. Scott staked FYDB cl 1-16 (YB46665) overtop of the tailing impoundment area of the Whitehorse Copper Mine. Scott sampled the tailings in Jun/94 and drilled 7 shallow auger holes ( 22.5 m) the following January. In Dec/95 Scott drilled 7 deeper auger holes (38.1 m) which penetrated through the tailings pile. In Aug/2001 B. Scott drilled 14 auger holes (108 m) in the middle of the tailings impoundment area.

Capsule Geology

The Whitehorse Copper (New Imperial) property encompasses the Whitehorse Copper Belt, which consists of 28 old mines and showings along a length of 32 km on the western margin of the Whitehorse Batholith. Most of these are skarn deposits which are found both in limy sections of the upper Triassic Lewes River Group and in mid-Cretaceous granodiorite. Many skarns are related to irregularities (embayments, etc) in the margin of the stock and mineralization sometimes extends as much as 150 m from the contact.
Most deposits are lensoid or tabular with irregular edges, are mainly coincident with bedding, and usually dip steeper than 60 degrees, although some are irregular masses (Arctic Chief, Keewenaw) and others are flat-lying (Gem and Black Cub North). The best ore zones have a limestone hanging wall and a quartzite or silicate skarn footwall and appear to develop where limestone-quartzite contacts are within 90 m of, and parallel to, an intrusive margin. Two main types of skarn deposits are present: (a) Iron-rich, in which copper occurs with magnetite, serpentine, specularite, talc, chlorite and occasional pyrrhotite and pyrite, usually associated with relatively non-magnetic diorite and (b) Iron-poor (Silicate), which consist of a wide variety of contact minerals (garnet, diopside, wollastonite, tremolite, epidote, chlorite, calcite and quartz) and usually occur near strongly magnetic phases of diorite. Faulting, shearing and dykes are more common in iron-rich than in silicate skarns.

Bornite and chalcopyrite are the main copper minerals, although chrysocolla, native copper, chalcocite and secondary minerals are present in small amounts, together with minor molybdenite, scheelite, tetrahedrite and valeriite. The copper minerals occur as scattered grains, blebs, pods and stringers that clearly postdate the skarn minerals. Bornite predominates in the iron-rich skarns and is slightly more abundant than chalcopyrite in the silicate skarns. Chalcopyrite shows a tendency to be on the footwall or hanging wall of iron-rich skarns but is more evenly distributed through silicate skarn. Magnetite concentrates contain 0.01 to 0.06% gallium. Silver grade is proportional to copper grade but gold is more erratically distributed, being more abundant in the iron-rich skarn deposits.

Whitehorse Copper evaluated at least 12 zones grading between 0.71% and 1.84% Cu. The deep portion of the Little Chief deposit, which occurs in an iron-rich skarn, is the only one which graded over 2% Cu and exceeded 1.2 million tonnes in size. The Keewenaw and Reservoir Lake deposits somewhat resemble porphyry deposits in that the mineralization is related to fracture networks in hornblende granite and is accompanied by weak alteration. Unmined reserves at the Cowley Park deposit are 213 200 tonnes grading 2.46% Cu and 0.14% MoS2. The 1987 drilling at Kodiak Cub intersected massive magnetite-serpentinite-bornite skarn that assayed 2.9% Cu, 4.46 g/t Au and 21.3 g/t Ag over 4.63 m.

In 1990, drilling by Aurora Gold near the old Grafter workings intersected 30.5 m of copper mineralization averaging 1.49% Cu, 0.38 g/t Au and 6.2 g/t Ag. The mineralization coincides with a north-trending IP anomaly. Trenching by B. Wallis near the Rabbit's Foot shafts exposed 6.1 m of coarse garnet-epidote skarn strongly mineralized with bornite and chalcopyrite. A chip sample from one of the trenches east of the shafts averaged 5.83% Cu over 0.9 m.

Scott staked the tailing impoundment areas in hopes of recovering economic quantities of magnetite and gold. A scoping study completed by Kilborn Ltd in 1984 estimated that the tailing impoundment areas host approximately 10 000 000 tonnes of tailings grading approximately 19% magnetite and a private report completed by Whitehorse Copper in 1985 estimated that the tailings contain approximately 1 500 kg of gold (or 0.15 g/t) (see introduction, Meinert, 1986). Six grab samples collected from the tailings in 1995 returned up to 0.45 g/t gold. The seven auger holes returned an average gold content of 0.24 g/t gold. The nine deeper holes drilled in Dec/95 targeted areas assumed to hold higher gold values. Gold assays ranged from 35 ppb to 827 ppb.

The majority of holes drilled in 2001 reached 9.1 m in depth which is the approximate limit of the drill employed. An average hole consisted of between 3.6 to 4.2 metres of fine dry grey sand, followed by up to 0.6 metres of wet grey clay, followed by fine wet grey sand to the end of hole. Fourteen composite samples returned an average gold content of 0.204 g/t gold (slightly higher than that reported by Whitehorse Copper) and 17.9% magnetite slightly lower than Kilborn¿s 1984 estimate.
