EXHIBIT "A" <br />SUMMARY OF 2016 ACTIVITIES <br />Updated topographic contours were collected in October and have been updated <br />in the 2016 Mine map. The permit boundary has been updated to the current mine <br />coordinate system and added to the 2016 Mine Map. <br />Reclamation hydro -seeding was completed on 3.75 acres adjacent to the inactive <br />pit in 2016. Temporary reclamation hydro -seeding was also completed on 4 acres <br />surrounding the ore stockpile to stabilize slopes and reduce runoff potential. <br />Approximately 3 acres of previously reclaimed active pit highwall and waste dumps were <br />disturbed in order to reduce the overall slope to 3:1 (H:V) and promote better re - <br />vegetation. The extra backfill space will also help as the waste factor has climbed to <br />more than 40% in 2016. The improved slope is nearly backfilled and should be fully <br />reclaimed in 2017. <br />Haul roads were treated almost exclusively with mag -chloride for dust control in <br />2016. Lignosulfate stabilizer may also be blended at 20-30% in select sections of haul <br />roads. Roughly 3,000 tons of road base were added to Eagle County 51 with Eagle <br />County Road Department personnel directing placement and compaction. A street <br />sweeping contractor is currently being used to help with pavement tracking throughout <br />the year. <br />Rock shipments from the "inactive" lower pit began in late October of 2016. The <br />lower pit has been idle since 2006. Roughly i Million tons of reserves remain under the <br />current operations plan for the lower pit. An updated operations and reclamation plan for <br />the lower pit will be submitted to CDRMS in 2017 for review. <br />Approximately 425,000 tons of gypsum rock were shipped from the mine during <br />2016. <br />
