Additionally, 2,600 feet of drift were completed on the Big Creek #4 level with plans to connect the Big Creek #4 and Countess portals to create a secondary escape way. 

Test mining was also conducted in 2011 and 2012 with mechanized equipment on three separate sublevels of the South Vein to determine vein characterization and optimal mining methods for future production.
