Exhibit C -Mining Plan 1. Mining will commence in the fall of 1987 and is estimated to continue until 2007. 2. Due to the combination of a sparsely / thin type soil combined with a talus rock overburden it is not fea le to seperate and stockpile topsoil by itself. New topsoil will be transported to the site and placed upon the regraded / reshaped overburden sites at the time of reclamation. , 3. The overburden lies adjacent to the marble layer (to be extracted) and down slope. This overburden will be dozed outward and downward and configured into a bench which will provide a working area to facilitate drilling equipment, front end loaders and haul trucks. 9. The marble layer which is to be quarried is approximately 80 feet thick and dips at 60° to considerable depth. It is planned to have Quarry faces of 40 to 80 feet in height with interveining benches of 90 to 60 feet in width. 5. Type of Mining Operation: This operation is for the extraction of White Marble (Limestone), and will be conducted as follows: Stripping of vegetated topsoil and overburden along side of a 60° dipping marble layer of approximately 80 feet in thickness. This stripping is accompolished by bull dozer to expose a fresh 'face' upon which drilling and blasting will break loose the marble material. A front end loader will load blasted marble into a haul truck for transport to Salida and the Butala Construction aggregate processing facility. No building structures will occur on the site. A 250 foot long access road (15 feet wide) will interconnect the Quarry site with Chaffee County Road No. 229. 6. The significant land disturbance will be the benched overburden areas of 120 feet to 200 feet in width and ultimately 650 feet in length. The quarried out area will have clean face cuts of 90 to 80 feet in height. • 7. Chaffee County Road No. 229 will be the primary haul road and is presently improved to facilitate haul trucks.
