Prince Albert Mine Plan of Operations Site Description <br />3.2 Current Mining Activity <br />The Prince Albert Prospect, or Bulk Sampling and Drilling, program under NOI P- 2005 -21 was the <br />only active mining operation in the area. Mining activity authorized under this Prospect NOI <br />consisted of accessing the ore deposit and confirming surface originated drill -hole data regarding ore <br />thickness and grade. This assessment was via a decline tunnel driven from the surface to the ore zone <br />for the purpose of collecting and shipping a 1000 -ton bulk sample of ore to a uranium ore processing <br />facility for amenability and product recovery testing (see Figure 2 "Existing Site Map "). <br />Mining facilities and disturbances currently included in the NOI consist of the following: <br />a. Re- opening the access road to the mine site from Montrose County Road U16. <br />b. Constructing ore and waste rock stockpile areas after stripping and salvaging topsoil and <br />vegetation from the appropriate locations. <br />c. Excavating a mine portal opening and decline tunnel of approximately 550 feet in length to <br />access the ore body. <br />d. Establishing stockpile(s) for salvaged growth medium. <br />e. Mining and shipping to an appropriate milling facility up to 1000 tons of natural uranium and <br />vanadium ore. <br />f. Setting up secure explosives magazines and tool storage. <br />g. Completion of one down gradient monitoring well to a total depth of 435 feet. <br />h. Structures and equipment include — A 20 -foot storage container; two explosives magazines; a <br />skidsteer loader; two "young buggy" underground haul trucks; a small air compressor; a <br />diesel - powered ventilation fan; two or more pneumatic "jackleg" drills; a crew truck; and two <br />monitoring wells. <br />Most of the initial mine development work and collection of the nominal 1000 -ton bulk ore sample <br />for the Prince Albert Mine was completed under P- 2005 -21. This Prospect NOI also includes a total <br />of 100 surface exploration drill holes. The surface exploration drilling program will continue to be <br />used to locate and define uranium ore deposits throughout the group of mining claims maintained by <br />Rimrock Exploration and Development, Inc. Note that not all uranium ore located is amenable to <br />mining from one particular location and the surface exploration work will not be limited to defining a <br />minable ore deposit that can be accessed from the existing Prince Albert Mine portal location. Ore <br />deposits discovered during the surface exploration work may have to be accessed from a location <br />separate from the Prince Albert mine operation. <br />Rimrock Exploration and Development Page 4 of 27 <br />
