YOAST MINE <br />2014 ANNUAL RECLAMATION REPORT (ARR) <br />2014 DISTURBANCE AREA <br />There were no additional acres disturbed during 2014. The total disturbed area in 2013 (2013 <br />ARR) was calculated at 848.6 acres. Historically in Colorado bond release tracking has been <br />done using maps generated in an AutoCAD format. Similar maps were recreated over the <br />years or existing maps were modified depending on need. This has led to an excessive <br />accumulation of copies of the same spatial layers (bond release polygons) with data stored in <br />maps rather than in individual layers. <br />The Colorado Bond Release Tracking Initiative was initiated in 2014 to improve management <br />of bond release polygon data and increase the efficiency and accuracy in the way bond release <br />is tracked. A GIS (Geographic Information System) was developed to allow for past and <br />present data to be kept in one updated layer. Use of GIS allows the ability to relate tabular <br />(table/ spreadsheet) information in a spatial context and to reach conclusions about this <br />relationship; in particular, acreages. <br />Polygons from past maps done in AutoCAD were consolidated into one polygon layer as a <br />base GIS shapefile. The AutoCAD generated seed maps included annual reclamation report <br />maps, bond status maps, veg sampling maps, bond release maps, seeding maps, etc... <br />Attribute information was created from information taken from the same maps in addition to <br />past Annual Reclamation Reports and Bond Release Submittals. Other information came <br />from existing staff and was added to a comments field in the attribute table. The polygons <br />were analyzed for gaps and overlaps and new acreages were assigned to individual polygons. <br />Once the process was complete a new disturbance area calculation was generated totaling <br />850.5 acres. <br />A copy of the Yoast Bond Release database has been provided to the Division of <br />Reclamation Mining and Safety (DRMS). Approval of the polygon areas and attribute data <br />should be completed as a part of review of this report. Once approved, the master copy of <br />the database will be kept at Seneca and edits to the database will only be made by a Seneca <br />representative. Any updates or changes will be approved by the DRMS and an updated copy <br />of the database will be provided by Seneca. The database will also be provided to private <br />contractors conducting vegetation studies so that acreages and attribute information remain <br />consistent. <br />BACKFILLING AND GRADING <br />There were no acres backfilled and graded in 2014 at the Yoast mine. <br />TOPSOIL AND SPOIL MONITORING <br />SCC is required by Permit C -94 -082 to monitor the salvage, storage, and redistribution of <br />topsoil and spoil handling operations at Yoast Mine. <br />
