Exhibit B - Index Map An Index Map is included with this amendment showing the location of the Speer Mining Resource. Exhibit C-Pre-Mining and Mining Plan Maps of Affected Lands Exhibit C has been amended to reflect the change in the reclamation plan. Exhibit C-1, the Pre-Mine Plan Map has remained the same. All sand and gravel has been mined from this site, so there is no real need for a new mine plan map, but a revised Exhibit C-2 (Mine Plan Map) for this site is being included to primarily show the location and type of backfill that will be implemented on the site for the new reclamation plan. A typical cross-section through the proposed fill is also presented. A new Exhibit C-3 (Adjoining Property Owners) is also being included to show all owners of properties within 200 ft. of the permit area who will be receiving notification of this amendment. There are no leaseholders or other mineral owners on the permit area. Exhibit E - Reclamation Plan Reclamation of the mined land of the permit area will be changed from the currently approved reclamation plan, that of being a sealed water-storage reservoir, to complete backfilling of the site to near pre-mine grade with clean fill dirt and other inert materials and a cap of clean fill dirt where required. The backfilled area will be seeded with a native grass seed mix and will be returned to an agricultural use. Approximately 26 acres remain as an open pit on this site, as all sand and gravel has been removed through the approved mining process. Some backfilling with clean fill dirt has already occurred on the south and east portions of the permit area. Approximately 1,000,000 cubic yards of clean fill dirt and inert materials will be required to backfill the Speer site to near pre-mine topography. These areas are shown on Exhibit C-2. Materials making up the backfill will be clean fill dirt for the majority of the site, and inert fill (as defined by Colorado State regulations) making up a lesser proportion of the site. A cross- section contained on Exhibit C-2 shows these areas. Inert fill is defined by the Colorado Dept. of Public Health and Environment (CDPHE) as: "Non-water soluble and non-putrescible solids together with such minor amounts and types of other materials as will not significantly affect the inert nature of such solids. The term includes, but is not limited to, earth, sand, gravel, rock, concrete which has been in a hardened state for at least sixty days, masonry, asphalt paving fragments, and other inert solids." Both the CDPHE and Adams County have more stringent standards for inert filling than the DRMS. ASCI is also seeking approval through both those governmental entities for approval to fill the Speer pit with inert materials. Attached at the end of this amendment
