Bell Copper Corp V.BCU

Alternate Symbol(s):  BCUFF

Bell Copper Corporation is a Canada-based mineral exploration company focused on the identification, exploration and discovery of large copper deposits located in Arizona. The Company is exploring its 100% owned Big Sandy Porphyry Copper Project and the Perseverance Porphyry Copper Project. The Big Sandy project comprises approximately 5,733 acres of mineral tenures, including 256 federal lode mining claims and 3 State of Arizona Mineral Exploration Permits, which is located 30 kilometers south of Perseverance. The Perseverance project is located in northwestern Arizona, approximately 19 miles southeast of Kingman and 150 miles northwest of Phoenix. The land package comprises a total of approximately 5244 hectares. The Company’s Perseverance porphyry copper/molybdenum project lies on a productive porphyry copper trend between Freeport's Bagdad mine and Origin Mining's Mineral Park mine in northwestern Arizona.

Copper Creek

Copper Creek

Sombrero Butte Project

At Sombrero Butte, Bell has purchased, optioned and staked a large contiguous land position in the southern region of the Copper Creek District. This land package represents the first consolidation of these claims since the area was mined back in 1920.

The Sombrero Butte property contains at least two main clusters of breccia pipes believed to be associated with one or more underlying porphyry copper systems. The breccia pipes in the northern cluster represent relatively small but high-grade copper deposits that are of greatest interest because of their suspected link to an underlying porphyry copper system. At least twenty distinct breccia pipes had been recognized by Bell Copper in the Sombrero Butte area prior to 2008, and 34 diamond drillholes were completed to test mineralization within the pipes and any shallow subjacent porphyry system.

Recent fieldwork has resulted in the discovery of 8 additional breccia pipes in a separate cluster located three kilometers further south. These 8 pipes constitute a distinct cluster covering an area of 1 kilometer by 1.6 kilometers. The newly discovered breccias share a common style of hydrothermal alteration consisting of relatively coarse grained (>100 microns), translucent, blue-green dickite (Al2Si2O5(OH)4) filling open spaces between angular breccia clasts. Wallrock surrounding the breccia pipes is in most places unaltered, or cut by sheeted tourmaline-quartz veinlets. The striking similarity of the alteration in these widely separated breccia pipes suggests that they shared a common hydrothermal reservoir, like a large porphyry copper system in the subsurface.

Dickite is an alumino-silicate clay that forms at temperatures of 150°-270°C under very acidic conditions. Primary potassium feldspar and secondary muscovite (sericite) in the breccias have been completely replaced by dickite, necessary mineralogical reactions to qualify as advanced argillic alteration. Positive identification of the dickite was made using a Pima infrared spectrometer as well as a microRaman spectrometer at the University of Arizona's RRUFF laboratory.

Hydrothermal alteration in the previously recognized breccia cluster 3 kilometers to the north ranges from chlorite-calcite-specular hematite-quartz-amethyst-adularia-rhodochrosite, to tourmaline-biotite-chlorite, to chlorite-sericite-hematite. Primary sulfide mineralization in the northern breccia cluster includes bornite-chalcopyrite and pyrite variably overprinted by steely supergene chalcocite. The presence of abundant dickite and gossanous iron oxides including jarosite within the southern breccia cluster adds a new and larger dimension to the footprint of this system.

X-ray fluoresecence analyses of iron oxide minerals in the dickite-bearing breccias show anomalous copper, molybdenum, and arsenic concentrations. Multiple young porphyry dikes up to several hundred meters long cut the host rocks surrounding the breccia pipes, and the porphyries are present as angular, rotated clasts within some of the breccias. Abundant copper oxide minerals, including the relatively rare mineral vesignieite (BaCu3(VO4)2(OH)2) are present at the surface in two widely separated breccia bodies that do not appear to carry dickite. Tourmaline is locally very abundant outside the breccia pipes as vein fillings and vein envelopes in sheeted, steeply dipping vein sets that do not seem closely linked to the dickite bearing breccias.

Future drilling at Sombrero Butte will be focused on the dickite-bearing breccia pipes because of the role that dickite plays in some exceptional porphyry copper deposits in Arizona and elsewhere around the world. Dickite is known in several of Arizona's major, higher grade porphyry copper systems, including Resolution, Bisbee, and San Manuel (19 kilometers west of Sombrero Butte). Dickite is also known at Oyu Tolgoi, Mongolia, Butte, Montana, Cananea, Mexico, and El Salvador, Chile. In these deposits dickite is associated with higher grade copper minerals such as digenite, chalcocite, and bornite.

In my humble opinion...............The developments over the past year in this Copper Creek district, by both Bell Copper and Redhawk Resources, could prove to be very significant over the coming months.

Cheers
