The decline shaft is 473m-long and was started in the fourth quarter of 2011 and was completed in July 2013 as part of the first phase. The first 70-80m were driven through sand overburden and the shaft had be lined as it progressed so it would not collapse. A conventional drill and blast technique was used beyond there down to the 150m level, and the decline was concrete-lined using precast concrete segments forming a ring.
