Bell Copper's Kabba K-11 hole finds 14 m of Cu sulphide

2015-07-28 12:54 ET - News Release

Dr. Timothy Marsh reports

KABBA DRILL PROGRAM UPDATE

Drilling on Bell Copper Corp.'s K-11 drill hole on the Kabba prospect encountered a long interval of visible copper and molybdenum mineralization hosted entirely by strongly altered and veined Laramide porphyry. A new hole, K-12, is being permitted to follow up on the pyrite-rich mineralization seen in K-11. Brown Drilling of Kingman, Ariz., has been selected to drill a 400-metre precollar for K-12, and Godbe Drilling LLC of Montrose, Colo., will drill the core tail.

Hole K-11 penetrated postmineral gravel and basalt cover rocks, and entered oxidized, leached and sericitized porphyry 542 metres below surface before cutting a 14-metre-thick blanket of supergene chalcocite (copper sulphide) starting at a depth of 564 metres. The thickness of this chalcocite interval is believed to be nearly a true thickness, in that the overlying postmineral rocks were bedded at an average angle of 80 degrees to the vertical drill hole. The supergene blanket consisted of sooty to steely grey coatings of chalcocite on abundant disseminated and veinlet-style pyrite.

Beneath the supergene chalcocite blanket was a long interval from 578 metres to about 1,410 metres that typically carried around 5 volume per cent disseminated- and veinlet-style pyrite, common quartz-molybdenite veinlets, and variable but generally low amounts of chalcopyrite. In most intervals, pyrite greatly exceeded chalcopyrite in abundance. A short interval near 1,185 metres depth was characterized by bornite-digenite copper minerals, again closely associated with pyrite. This uncommon mineral association is characteristic of the high-grade upper parts of the giant Resolution deposit, also in Arizona, and it attests to the capacity of the Kabba system to produce high-sulphidation-state copper minerals. Late-stage fluorite, another mineral common to the Resolution system, was observed as veinlets in K-11.

Hole K-11 was finally terminated at a depth of 1,431 metres in propylitically and potassically altered dacite porphyry carrying scattered pyrite and ankerite veinlets.

Quantitative determination of the amount of copper encountered in the K-11 core will require splitting and sampling, followed by assaying at an independent analytical laboratory. Core will be split and sampled in a locked compound at the laboratory in Tucson, Ariz. Control samples, including field blanks and copper standards, will be inserted into the sample stream by Bell at an average rate of one control sample per 15 unknowns.

Qualified person

The technical content of this release has been reviewed and approved by Dr. Timothy Marsh, PhD, PEng, the company's chief executive officer and president, a qualified person as defined by National Instrument 43-101. Dr. Marsh's qualifications as qualified person derive from his registration as professional engineer (geological) No. 34499 in the state of Arizona, and as registered member No. 4047103 of the Society for Mining, Metallurgy and Exploration. No mineral resource has yet been identified on the Kabba project. There is no certainty that the present exploration effort will result in the identification of a mineral resource, or that any mineral resource that might be discovered will prove to be economically recoverable.

"This long intersection of strongly altered and mineralized porphyry leaves little room for doubt that Bell has found the faulted top of the Kabba porphyry at K-11. The presence in our core over many hundreds of metres of macroscopic copper and molybdenum mineralization, together with the vein types and hydrothermal alteration minerals typical of a porphyry copper system, gives us the confidence to expect to find a copper shell commensurate in size with the large pyrite shell that we have now drilled in K-11. We know from incredible outcrops that display the roots of the Kabba system over many square kilometres that more intense mineralization, veining and alteration than was encountered in K-11 remain to be discovered in the upper plate of the fault. The much stronger induced polarization response at the proposed K-12 site gives Bell good reason to expect that the supergene chalcocite blanket found at the top of the K-11 sulphide zone will be strong at K-12.

"The great depth to which Bell was able to pursue this exciting porphyry intersection was due entirely to the expertise and enthusiasm of our driller, Godbe Drilling LLC. Their 40 years of diamond drilling experience throughout the Americas, combined with the high mechanical availability of their drill and close logistical support out of their Willcox, Ariz., field office, allowed the K-11 drilling operation to succeed in challenging rock formations where other major drilling companies have failed.

"Godbe's ongoing commitment to support Bell's work on the Kabba project is driven entirely by what they saw coming out of the ground. We now have a talented drilling partner who fully understands the magnitude of the discovery that we are pursuing. Bell is pleased to have Godbe as a partner going forward at Kabba.

"The company will work to advance the drillout of the Kabba porphyry until the full extent of copper mineralization is determined. We believe that K-11 represents the prelude to a significant Arizona copper discovery."
