CARMACKS COPPER-GOLD BELT

Carmacks Copper Project

Western Copper Corporation's (WRN:TSX, www.westerncoppercorp.com )100 per cent owned Williams Creek property is located 50 kilometres southeast of Sherwood Copper’s Minto Mine, 200 kilometers north of Whitehorse in the Yukon Territory, Canada.

On May 24th, 2007 Western Copper Corporation announced that an independent feasibility study by M3 Engineering & Technology Corporation of Tucson, Arizona (“M3”) concluded that development of the Carmacks copper property can be achieved with an after-tax internal rate of return (IRR) of 15.7%, based on 100% equity financing. The project has an undiscounted net present value (NPV) of C$123 million, with payback of initial capital investment realized in 3.9 years.

The proposed development plan is for an open pit mine with an acid heap leach followed by solvent extraction and electrowinning. Over the projected 6 years of operation the mine will produce a total of 208 million pounds of pure cathode copper of grade equal to or exceeding LME Grade A.

The development plan proposed in the study considers a construction start in early 2008 with pre-stripping of the mine commencing concurrently. Production of copper is targeted for the fourth quarter of 2009. The current reserve estimate would sustain mine production for 6 years. Following this, rinsing of the heap would commence with further recovery of copper before neutralization and reclamation of the heap is completed.

Western Copper has commenced a 10,000 metre diamond drill program targeting sufficient additional oxide reserves to extend the life of the project well beyond the 6 year mine life proposed in the feasibility study.

Mineral Resource and Reserve Statement

The following tables illustrate the Carmacks Mineral Resource and Reserve estimates accompanying Western Copper’s May 24th, 2007 news release.

Geology and Mineralization (abridged from Western Copper Corporation’s website)

The Carmacks Copper, copper-gold deposit lies within the Yukon Cataclastic Terrane. The deposit is hosted by feldspathic mafic gneisses (generally quartz deficient) that form a roof pendant within Upper Triassic hornblende-biotite granodiorite of the Granite Mountain Batholith.

The majority of the copper found in oxide portion of the No. 1 Zone is in the form of the
secondary minerals malachite, cuprite, azurite and tenorite (copper limonite) with very minor other secondary copper minerals (covellite, digenite, djurlite). Other secondary minerals include limonite, goethite, specular hematite, and gypsum. Primary copper mineralization is restricted to bornite and chalcopyrite. Other primary minerals include magnetite, gold, molybdenite, native bismuth, bismuthinite, arsenopyrite, pyrite, pyrrhotite and carbonate. Molybdenite, visible gold, native bismuth, bismuthinite and arsenopyrite occur rarely. The upper 250 m of the No. 1 Zone is oxidized.

Exploration History (abridged from Western Copper Corporation’s website)

The property was first staked in 1970 and since that time has been the subject of various
exploration campaigns comprising trenching, diamond drilling, reverse circulation drilling, geophysical, and geochemical surveying. Prior to 2006, a total of 80 diamond drill holes and 11 reverse circulation holes, totaling 12,900 m of drilling, had been completed in the exploration of the property. In addition, over 8,000 m of surface trenching was completed. The majority of this work focused on the No.1 Zone and was completed before the mid-1990’s.

In 2006 a new exploration program was initiated on the Carmacks Copper property with a view to better defining the No.1 Zone and starting a more systematic exploration of the other known zones of mineralization. This consisted of diamond drilling and some rapid air blast drilling. The field program was suspended because due to freezing weather on November 17, 2006 after a total of 7,100 m in 34 drill holes diamond drilling had been completed.

The exploration drilling program recommenced in March 2007, initially focusing on zones immediately south of the proposed open pit. This program is planned to continue through the year.
