Annual Report — 2013 <br />Henderson Mine and Mill Reclamation Activities <br />Permit No. M- 1977 -342 <br />Henderson is currently developing a report of five quarters of water quality data for several of the <br />groundwater wells that were installed in 2012, as a part of the requirements in the Groundwater <br />Monitoring Plan. This will serve to assess baseline water quality and to establish a monitoring program <br />and point of compliance (POC) well locations moving forward. <br />Additionally, a report to assess the low pH measurements in the Mill POC monitoring well MLGW -7 is <br />being developed and will be submitted by March 31, 2014. <br />As a result of low pH measurements in the Mine POC monitoring well MNGW -1, a project is being <br />initiated to install additional monitoring wells to investigate the source of low pH waters and the <br />adequacy of the existing POC location and well construction. <br />2.3.7 — Gravel Pit Operations <br />Approximately 50,000 tons of material was crushed and screened in 2013. This material is being be <br />utilized for various road building and construction activities at the Henderson Mill site. Another 150,000 <br />tons of material is expected to come from this resource in future years. <br />3.0 Anticipated 2014 Activities <br />3.1 Prospecting <br />Prospecting activities for 2014 are currently being assessed and the required notice(s) of intent will be <br />submitted to the DRMS once they are established. <br />3.2 Tailinas Delivery Line <br />Henderson Mill will be undergoing a project during 2014 to enhance the structural integrity of the <br />droptower section of the tailing delivery line. This section of the tailing delivery line experienced several <br />issues during 2013. This project will help to alleviate those issues by providing more structural support <br />through additional steel and concrete applications. A request for a technical revision will be submitted to <br />the DRMS prior to this work commencing and will include a copy of the report completed by W.W. <br />Wheeler & Associates along with a full set of construction drawings. <br />Reclamation in 2014 will include continued topsoil salvage and stabilization at the Mill. New activity <br />will continue at the newly approved stockpile location at the head end of Ranger Gulch. <br />4.0 Financial Warranty <br />Draft revisions to the Henderson Mine and Mill Financial Assurance (FA) cost estimate were submitted in <br />2013 for review by DRMS staff. Henderson representatives and DRMS staff discussed the FA cost <br />estimates in a meeting held on January 28`h, 2014 and adjustments are now being made to the final cost <br />estimate. Henderson is working to complete the final cost estimate, incorporating DRMS suggestions, by <br />late March of 2014. The intent is to have this final number available for a hearing before the MLRB <br />seeking revisions to the Henderson Mine and Mill FA instruments. <br />Page 4 <br />
