DAILY DIARY <br />PROJECT: ALMA PLACER MINE <br />LOCATION: PARK COUNTY, COLORADO <br />SOURCE: BERM CONSTRUCTION <br />PROJECT N0: 1-4561-11191-10 REPORT N0: 7 DATE: 6/1$/90 <br />PROCTOR N0: N/A TIME: 10.D HOURS <br />SAMPLE N0: 1 ENGINEERING TECHNICIAN: DEA GELIS <br />YORK PERFORMED: <br />Fill placement continued today in all areas excluding the bench n the inside of <br />the berm near the south pond. Fill placement did continue on th outside of the <br />berm in this area, as the subgrade material was observed to be stable and the <br />minimum compaction requirements were met. The next lift plac ed in the area <br />however, again contained very moist clay. <br />i <br />I <br />REMARKS: <br />Mr. Fred Ladd arrived at the site at approximately 10:30 a.m. Fred observed <br />equipment travel over the inside of the berm near the south pond. Fred suggested <br />removing 1.5 to 2.0 feet of the existing subgrade, and then plac ing rock in the <br />unstable areas on both sides of the berm. <br />This afternoon, following Mr. Ladd's site visit, rock was hauled i to the unstable <br />areas using a front end loader. One push cat was required to ai the front end <br />loader at the rock stock pile, while the other push cat was used to level the rock. <br />Fill operations did not take place in any other areas this after on. The front <br />end loader was used repeatedly to roll rock into the unstable area n the inside of <br />the berm. It was observed that the pond side of the bench was be inning to creep <br />our towards the pond where the majority of the rock had been laced, and the <br />subgrade material was still quite unstable. Reclamation Resources, Inc., moved out <br />of the area and spent the rest of the afternoon placing fill mater al to the north <br />in areas which were stable. <br />Six nuclear density tests were performed at the given locations and elevations. <br />The test results indicated that the minimum compaction requirements were not met at <br />the test locations. <br />with Reclamation Resources, Inc., pAne.lin6grmRdrof today's test res lts. <br />I <br />~''I1~~/~~j~~~/~ GEOTECNNICAL.
