Mineralization. The chrome ore mineralization is strictly confined to the ultramafics and occurs at six different stratigraphic levels Band-I is continuous for a greater distance and is thickest all the chromite lodes. It bears a gradational contact with the wall rock. The ultramafics in the form of veins do occur in many places within the chromite lode.

Mineralization. Past production focused solely on oxidized ore. Oxidation is extensive in the CX-Pxxxxx fault system, affecting the entire length of the zone and penetrating up to 1500 feet in depth. The oxidation process generated pervasive limonite, hematite, and other iron and arsenic oxides. Oxidation is variably developed in the Range Front fault. In some fault and shear zones, oxidation is present at depths of 1800 feet; in other places oxidation gives way at shallow depths (<500 feet) to sulfide mineralization. Sulfide mineralization is a pervasive event consisting of two stages of pyrite development, a non-ore pyrite, and an ore-stage axxxxxxx pyrite. In hand specimens, gold bearing pyrite is a dull brassy to black color and extremely fine-grained. Remobilized carbon is usually associated with the pyrite, giving the sulfides a “sooty” appearance. Gold is primarily contained in pyrite, or found as rims around fine pyrite grains (Wxxxxxx and Wittkopp, 1983, Fxxxxx, 1994). Detailed geochemical work suggests there is also a primary positive Au-Hg (and weaker Au-As) correlation, as well as a negative Au-Ba association, which is preserved in the unoxidized environment (Fxxxxx and Kxxxxxxxxx, 1991). No other major elements (Pb, Zn, Cu, Mo, F) show any positive or negative relation to Au.
Mineralization. Mineralization in Mega Pit occurs in several environments, including fracture fillings in what are likely feeder zones; as passive disseminations in permeable beds bounded by mafic sxxxx; and as massive replacements in structurally incompetent fold hinges. The mineral suite consists principally of auriferous pyrite, supplemented by axxxxxxx pyrite, orpiment, stibnite, and rare realgar. The fracture fillings require brecciation and a permeable matrix. The passive disseminations depend on prior decalcification of the sedimentary rock within the igneous 'sandwich'. The massive fold-hinge replacements depend primarily on pre-existing silicification, which can be shattered upon folding. In spite of the variety of ore environments, the hydrothermal system is quite linear, and confined to a N-S corridor centered on the midline of Sections 6, 7, 18, 19 & 30. Along this corridor, it is clear that the mineralizing system is opportunistically exploiting all potential hosts along its longitudinal path, and. transgressing north-dipping stratigraphy from south to north, within a fairly restricted vertical interval, so that the principal hosts migrate upsection as follows:
Mineralization. Material information in the control or possession of the Seller, its Affiliates or any Inmet Party relating to Project mineralization has been made available to the Purchaser and such information has been prepared in a manner which is consistent with accepted practice in the mining industry, the statements, assumptions and projections contained therein are fair and reasonable as and when produced and, to the knowledge of the Seller have been arrived at after reasonable inquiry having been made in good faith by the persons responsible therefor.
Mineralization. In accordance with the Commission’s Guideline on Non-Reserve Mineralized Material, and as shown in the following table, the Borrower estimates 136.2 million pounds of in-place mineralized uranium material on the Borrower’s New Mexico properties as of September 1, 2012. The estimate for each New Mexico property is based on studies and geologic reports prepared by prior owners, along with studies and reports prepared by geologists engaged by the Borrower. The estimates presented below for Mancos, Churchrock, Nose Rock, West Largo, Roca Honda, Crownpoint and Ambrosia Lake were reviewed and affirmed by Xxxxx Xxxxxxx & Company (USA), Inc., an independent private mining consulting firm in their report dated February 26, 2008. Since the date of the report, the Borrower has maintained its ownership position of these properties, the properties have not been subject to any production activities and the estimates remain unchanged. On August 31, 2012 the Borrower completed the acquisition of Neutron. The Xxxxxxx, Southeast, Area I, Area II, Area III and Area V were added to the Borrower’s New Mexico portfolio. These properties were not part of the Xxxxx Xxxxxx report. Non-reserve mineral resource estimates attributed to the former Neutron properties now under the Borrower’s control were prepared by Neutron’s technical staff.

Mineralization. The Monster Property mineralization is hosted within and directly adjacent to the Xxxxxxxx Breccia. Cobalt occurs on the property as cobaltite and erythrite, in veins and disseminations. Copper occurs on the property as chalcopyrite and bornite, in veins, veinlets, blebs and disseminations. Fourteen mineralized zones have been described from the Monster Property during historical work. Two of these zones are the South Co Zone (Baknes, 1995), and the Goblin Showing (Xxxxx, 1999). The South Co Zone is a 50 x 70 m poorly exposed zone of carbonate altered and silicified dolostone, mineralized with cobaltite and chalcopyrite. One grab sample reported in Baknes (1995) contained 2.80% Co and 1.70% Cu. The Goblin Showing is a zone of concretionary shale and dolomite with abundant quartz- carbonate veins, that hosts chalcopyrite, bornite, and minor cobaltite. Seven contiguous representative grab samples reported in Xxxxx (1999) contained 0.56% Cu over 35 metres. None of the historical data has been verified by the company.
