AmerAlia, Inc. INTRODUCTION AM2 Drilling and Completion Report This report summarizes the data and information generated during the drilling and completion of AmerAlia, Inc.'s alluvia] monitoring well AM2 in late January 2000. LOCATION, DESCRIPTION, AND HISTORY AM2 is located on Mazathon Oil Company property, just outside the most easterly part of the Rock School Lease (Federal Sodium Lease C-0119985), Rio Blanco County, Colorado (Figure 1) in the Northeast Quarter of the Northwest Quarter of Section 21, Township 1 South, Range 98 West, at a ground elevation of 6,274 feet (Figure 2). More specifically, AM2 is 1,129.6 feet from the north line of Section 21 and 1,649.7 feet from the west line of Section 21. AM2 was completed as a groundwater monitoring well for the Yellow Creek Alluvial Aquifer System (Figure 3) at a total depth (TD) of 90 feet. Personnel from Daub & Associates, Inc., were on site intermittently during drilling and completion of the well. Table 1 briefly summarizes the drilling history of AM2. Collins Drilling Company of Glenwood Springs, Colorado, mobilized a rotary pull-down rig to the location on January 28, 2000, and drilled a 7-e'-inch-diameter hole from the surface to 48 feet. Dry compressed air was used as a circulation medium. Drilling resumed on January 29, 2000, from 48 feet to 90 feet (TD). Drilling of the well concluded on January 31, 2000. As illustrated in Figure 4, the well was completed using gravel- and sand-packed 42-inch PVC casing (with the lower 40 feet slotted). Table 1 provides a narrative describing the completion process. STRATIGRAPHIC INTERCEPTS AM2 spudded in surface colluvium and alluvium associated with the valley-fill of Yellow Creek. These unconsolidated sands and gravels continued to a depth of about 82 feet. From 82 feet to TD (90 feet), the bit penetrated the weathered and fractured Uinta Formation (Figure 4). Daub & Associates, Inc.
