(Page 2) MINE ID # OR PROSPECTING ID # M-1977-223 INSPECTION DATE 10/25/2007 INSPECTOR'S INITIALS DEZ OBSERVATIONS This inspection of Permit Number M-1977-223 (Wiley Pit) was conducted by Deb E. Zack of the DRMS due to an approved succession of operator's application. Mike Jacobson, Five Rivers Ranch Cattle Feeding LLC representative, was unavailable at the time of this inspection. The pit is located approximately 1 mile north of Lamar, CO and currently consists of approximately 87 acres, of which approximately 18.25 acres appear to be at various levels of disturbance. The mine entrance identification sign and permit boundary markers must be clearly posted per Rule 3.1.12(1)(c) and Rule 3.1.12(2) (see Problem No. 1 on pg. 3). The topsoil stockpile runs along the western extent of the permit boundary (see photo 1). This inspector collected the following information using the Division's Trimble GPS unit: • The dimensions of the topsoil stockpile were calculated to be approximately 20'(h) by 30' (w) by 960' (I) making the total approximate cubic yardage 21,333 cuyds. • The pit area is approximately 2,115 linear feet, and is high walled. • The total acreage of the disturbed area is approximately 18.25 acres. The majority of the site to the north and east appears to have not been disturbed at all at the time of this inspection. However, over the center of the western portion of the site (where the pit lies) substantial amounts of earthmoving would be necessary in order to bring down the high wall that exists, and to reapply topsoil across the area. These two criteria, as well as components of revegetation such as seeding, mulching and fertilization, are the main factors of the bond calculation that is forthcoming. This bond calculation and any corresponding requirements will be sent to the current operator under separate cover in the near future. Finally, Tamarisk were observed during this inspection, mainly on the pit floor (see photos 1, 3 and 4). The Operator is advised to treat the Tamarisk, while the infestation is relatively small and localized, with an approved herbicide, or excavate and dispose of the Tamarisk while the site is being worked. If the Operator chooses to address the Tamarisk problem while the site is being worked, the Division will require a letter committing the Operator to this course of action. If the Operator decides to spray or otherwise treat the Tamarisk with chemicals, then a weed control and management plan must be created per Rule 3.1.10(6) on or before April 30, 2008 (see Problem No. 2 on pg. 3). This plan should be developed in consultation with the county extension agency, or weed control district office, and should include specific control measures to be applied, a schedule of when the control measures will be applied, and apost-spray monitoring plan. The operator is advised that this site will not be released if Tamarisk is found on site, and must, therefore, be removed or treated adequately prior to pnancial warranty release. See the enclosed Division-approved recommendations for Tamarisk control. All other activities and completed work at the time of inspection appeared to follow the guidelines and regulations set forth by the state and in the mining and reclamation plans for the pit. At the time of this inspection there appeared to be no long-term (greater than 72 hours) water retention. The site is stable and no disturbance was observed outside of the approved permit boundaries.

Zack at the Division of Reclamation, Mining and Safety, Denver Office, 1313 Sherman Street, Room 215, Denver, Colorado 80203, phone number 303-866-4179.
