Structure: Roberts Mountains Thrust; Cortez Window North-trending shear zones

Alteration: silicification and bleaching of carbonate rock near fissure veins

Commodity: Ore Materials: gold, tetrahedrite, galena, pyrite, argentite, sphalerite, chalcopyrite in old Emma Mine mine ore Gangue Materials: gangue of iron and manganese oxides and calcite, quartz. Arsenopyrite was reported in the gold ore with calcite, realgar, orpiment, stibnite, quartz and pyrite.

Deposit: The old Mill Canyon Mine (Emma E. claim) was developed on polymetallic sulfide-bearing fissure veins in north-trending shear zones. The current target is disseminated gold hosted by Wenban limestone. In 2003, Victoria reported that mapping had delineated four major, northwesterly striking, gold-bearing structural systems, which occur in the NW, N-S, WNW and NNE structural systems. Several major intersecting zones, which are currently the focus of the second phase sampling, occur within the belt. These intersection zones carry the higher grades of up to 104 g/T gold in Victoria's geochemical sampling. Some of the existing targets, inherited from previous holders of the property are located within these intersection zones as well. The intersection zones mapped to date plunge southeasterly in areas not yet evaluated by previous drilling. Victoria plans to establish the geometry of these intersection zones to test some of the older, yet viable targets such as Open Cut with surface channel sampling of 83.20 metres at a grade of 8.9 g/T. The Company will also assess the volume potential before drilling. Located approximately 3 km northwest of Open Cut, step-out drilling from previous mining company intercepts of 1.52 metres at 97.98 g/T, and 7.62 metres at 6.47 g/T in skarn zones that were cut by two drill holes 200 metres apart, will also be a focus for future drilling. Victoria's work indicates that the adjacent Cortez Hills and Cortez Mine deposits ore bodies were down-dropped steeply to the west from the Mill Canyon property. Victoria is currently working on restoring their original, pre, post-mineral fault positions with respect to the Mill Canyon structural systems to enhance prioritization of structural targets for driling.

Deposit type: Carbonate-hosted Au-Ag

Development: Victoria Resource Corp. acquired the Mill Canyon property along with the Hilltop-Slaven and Preble-Prinson properties from Newmont early in 2003. Victoria planned a drilling project on the Mill Canyon property which is adjacent to the old Cortez and Horse Canyon Mines and 1.6 kilometres east of Placer Dome's recently announced 5.5 million ounce Cortez Hills gold discovery. Drlling was planned to test the northwest extension of the "Horse Canyon Corridor" which hosts the Horse Canyon mine and other active exploration drilling areas to the southeast. Victoria plans to commence a drill program at Mill Canyon in the fall of 2003 pending the receipt of drill permits. In Jan. 2004, Victoria Resource Corporation announced initial diamond drill results from the Mill Canyon Property in Nevada. 2004 drilling at the Mill Canyon Project concentrated on the Open Cut target which is believed to be in a structurally similar environment to the Cortez Mine and the Cortez Hills discovery. A total of 5 holes totaling 935 metres have been drilled to date and assay results have been received from 3 of the 5 holes. Hole OC-5 encountered four separate intercepts of "Carlin Style" gold mineralization which are: 3.1 metres of 26.38 grams per tonne gold (g/t), 8.8 metres of 16.83 g/t gold, 26.2 metres of 3.82 g/t gold and 17.4 metres of 3.60 g/t gold. A second drill has drilled 2 holes totaling 589 metres at the Scorpion King target located 2 kilometers northwest of Open Cut. No significant results have been received to date and the drill will move to the Open Cut target as soon as the planned holes at Scorpion King are completed.

Geology: Generally north-trending shear zones were invaded by hydrothemal ore fluids.
