Geologically, the main hosts for uranium-vanadium mineralization in the Sunday Mine Complex are fluvial sandstone beds assigned to the upper part of the Salt Wash Member of the Jurassic Morrison Formation, with minor production coming from conglomeratic sandstones assigned to the lower portion of the Brushy Basin Member of the Morrison Formation. Mineralization from both members is present at the property, with the mine production coming from the Salt Wash Member. Beds generally strike NW-SE and dip SW, with some exceptions within fault bounded blocks adjacent to Big Gypsum Valley.

According to the USGS Bulletin 1693 (Cox, D.P., and Singer, D. A., eds., 1986), the Deposit Model for the project is Model 30c, Sandstone Uranium – Tabular subtype.

Mineralogy: Uraninite, coffinite, pyrite in organic-rich horizons. Chlorite common.

Texture/Structure Stratabound deposits. Tabular U--intimately admixed with pore-filling humin in tabular lenses suspended within reduced sandstone. Replacement of wood and other carbonaceous material. Roll front U--in crescentic lens that cuts across bedding, at interface between oxidized and reduced ground.

Alteration Tabular--Humic acid mineralizing fluids leach iron from detrital magnetite- ilmenite leaving relict TiO2 minerals in diagenetic ores. Roll front- Oxidized iron minerals in rock updip, reduced iron minerals in rock downdip from redox interface.

Ore Controls Permeability. Tabular--Hu ........

The historic mining on the property, was originally by rail, then converted to a trackless underground mine in the 1970’s. Ore extraction used jackleg drilling and a random room and pillar mining method. Split shooting of ore and waste to maintain grade was common.

Traditionally in southwest Colorado and southeast Utah, uranium and uranium-vanadium deposits were owned or controlled by mining companies of various sizes. Some mines were controlled by the companies that owned the mills, but many mines had owner/lessees that shipped their ore to the regional mills. To which mill to ship depended on the toll contracts and the mineralogy of the uranium and host rocks.

The mills were conventional surface facilities that processed the ore to obtain the uranium. Conventional milling is one of the two primary recovery methods that are currently used to extract uranium from mined ore. A conventional uranium mill is a chemical plant that extracts uranium using the following process:

1. Trucks deliver uranium ore to the mill, where it is crushed into smaller particles before being extracted (or leached). In most cases, sulfuric acid is the leaching agent, but alkaline solutions can also be used to leach the uranium from the ore. (In addi ........
