The Axe (Adit zone) prospect outcrops along the steep west side of the Summers Creek valley, about 600 metres west of the creek and 21 kilometres north of Princeton.

This area along Summers Creek is underlain by the Eastern volcanic facies of the Upper Triassic Nicola Group, comprising mafic, augite and hornblende porphyritic pyroclastics and flows, and associated alkaline intrusions. These rocks are intruded by granodiorite and quartz diorite of the Middle to Late Cretaceous Summers Creek pluton.

This prospect is part of the Axe property, a large porphyry system some 3.2 kilometres in diameter, containing three significant zones of copper mineralization, including the Adit zone. The other two zones are the South (092HNE040) and West (092HNE142) zones. The Adit zone is 800 metres north of the South zone and 930 metres east-southeast of the West zone. This porphyry-copper hydrothermal system is related to the intrusion of small stocks and dikes of fine- grained diorite and monzonite through the West and Adit zones. These intrusions are interpreted to be part of the Nicola magmatic suite and may represent the deeper part of Nicola volcanoes.

The Axe (Adit zone) is largely hosted in a stock of porphyritic micromonzonite, 1500 by 500 metres in area, intruding basaltic to andesitic flows and tuffs of the Nicola Group (Central belt, Bulletin 69). The micromonzonite is comprised of 25 to 45 per cent plagioclase crystals and up to 10 per cent hornblende crystals in a matrix of orthoclase. The stock is cut by a few coeval porphyritic diorite dikes. The northern one-quarter of the deposit is hosted in sericite schist derived from strongly sheared flows or tuffs. Minor andesitic to basaltic, granodioritic and rhyolitic dikes of Cretaceous or Tertiary age cut all other rock units.

The hostrocks are strongly faulted, fractured and sheared in all orientations. One prevalent fracture set strikes 045 degrees. A major northeast-striking fault, dipping steeply northwest, traverses the area of copper mineralization. This structure is part of the north-striking Summers Creek fault system.

The monzonite stock and surrounding volcanics are strongly chloritized pervasively and along fractures. Epidote commonly accompanies the chlorite and also forms fracture fillings and irregular veins, usually with calcite. Strong zones of albitization are locally present. Fine-grained biotite often accompanies chlorite. Gypsum veins up to 1.5 centimetres wide occur at depth. Limonite and manganese staining are very common in the upper 30 metres of the zone. Malachite and azurite occur frequently in outcrop, usually along shears and fault zones. Surface exposures are intensely leached and clay altered. Clay is also developed along the numerous shears and fault zones.

Sulphides form up to 20 per cent of the zone and consist of pyrite, chalcopyrite, minor molybdenite, chalcocite and bornite and rare pyrrhotite. They are commonly disseminated and occur to a lesser extent in veins and fracture fillings. Chalcopyrite exceeds pyrite in areas of stronger mineralization. Chalcopyrite and pyrite tend to be disseminated in pervasive chlorite, epidote and albite, and along fractures with chlorite and epidote. Molybdenite occurs in chlorite-lined fractures, as irregular stringers and as disseminations in locally strong, pervasive epidote alteration. The bulk of the copper mineralization appears to be older than molybdenum mineralization, which may be associated with the Summers Creek stock.

The numerous scattered copper occurrences comprising the Adit zone outcrop over a north-south distance of 1400 metres and an east-west distance of up to 800 metres. Diamond drilling has intersected significant copper mineralization in a 500 by 400 metre area in the southwestern part of this zone. Drilling up to 1973 has defined indicated reserves of 14,513,600 tonnes grading 0.56 per cent copper (Northern Miner - September 6, 1973). Silver values are generally low. One drillhole analysed 0.54 per cent copper and 3.3 grams per tonne silver over 53.6 metres (Assessment Report 9896, page 12, hole 73-3). A second hole graded 0.0677 per cent copper, 0.420 gram per tonne gold, 35.2 grams per tonne silver and 0.551 per cent zinc over 3.05 metres (Assessment Report 10886, Appendix G, hole 82-3, sample R82 11612).

The Axe (Adit zone) was first explored with a 30-metre long adit, excavated some time in the mid to late 1930s. Quintana Minerals Corporation conducted geological mapping and drilled several rotary holes in 1968. Amax Exploration Inc. completed various geological, geophysical and soil geochemical surveys and drilled 7 percussion holes and 6 diamond-drill holes between 1969 and 1971. Adonis Mines Ltd. carried out additional geological mapping and drilled 24 percussion holes and 9 diamond-drill holes in 1972 and 1973. No work was done on the property from 1974 to 1979. The property was then optioned by Global Energy Corporation (formerly Adonis Mines) to Cominco Ltd. in 1980.

From 1980 to 1993, Cominco earned a controlling interest in the claims by completing work programs during the period 1980-1983. During this period, they compiled all historical data, abandoned all original claims and re-staked the Axe 3000, 4000, 5000, 6000 claims. They also completed magnetometer, VLF electromagnetic surveys, rock and soil geochemistry, and drilled six diamond drill holes totaling 765 metres. In 1991, Cominco drilled eleven percussion holes totaling 375 metres in an area of gold soil anomalies. This program was unsuccessful for the most part in penetrating deep overburden.

In 1994, Cominco sold the claims to the Predator Syndicate, who maintained the claims to their status in 2004. The claims were transferred to Kenneth L. Daughtry, who held the claims in trust for the syndicate until March 2003. From 1997 to 2000, the property was optioned to Causeway Mining Corp. They performed a work program in 1998 consisting of an IP survey, reviewing of available drill core, rock chip sampling and staking five additional claims.

In 2003, Bearclaw Capital Corp. entered into an agreement to option the Axe property. John Kerr prepared an Instrument 43-101 report on the Axe Property in October, 2003. In his report, Mr. Kerr reported an indicated resource in the Adit Zone of 6.1 million tonnes grading 0.59 per cent copper at a cut-off of 0.25 per cent copper.

In 2004, Bearclaw Capital Corp. drilled three diamond drill holes, totaling 297.8 metres, on the Adit Zone of the Axe property in March and early April, 2004. The holes were drilled to test the oxide copper potential of the weathered zone of a previously drilled porphyry copper prospect and the following results are derived from Bearclaw Assessment Report 27516. Two holes have intersections of oxide-only mineralization. The oxide zones are 13.5 and 43.5 metres in length, with grades of 0.10 and 0.13 per cent oxide copper, respectively. Two holes have intersections of oxide and possibly supergene sulphide copper mineralization. These zones are 33.0 and 10.5 m in length, with grades of 0.19 and 0.11 per cent sulphide copper and 0.12 and 0.22 per cent oxide copper, respectively. The total copper grade is about 0.3 per cent copper. All holes encountered primary copper sulphide mineralization. The intersections are 15.0, 3.6 and 23.6 metres in length, with grades of 0.17, 0.15 and 0.52 %, respectively. Later in 2004, a reverse circulation program was completed on the property. Results are pending.

Exploration and Mining in BC for 2003 and 2004 reports the following inventory which is based on previous drilling, totaling about 14,000 metres in 185 drill holes. This drilling defined four mineralized zones with an aggregate indicated resource of 39,100,000 tonnes grading 0.39 per cent copper (at a 0.25 per cent copper cut-off), along with an inferred resource of 32,000,000 tonnes at similar grade. The overall resource is said to include an inferred oxide resource of 8,500,000 tonnes grading 0.54 per cent copper. The gold content has not been determined.
