Stantec // Oceana Gold NZ Ltd // Waihi North Project Transportation Assessment 17 Figure 26 Mine Workforce 2001 to 2016 It is noted that activity in the Martha Pit reduced significantly to occasional maintenance work as a land slip in 2015 effectively suspended the work within the pit. Following the slip, the mine workforce has been steadily decreasi ng and in 2016 the workforce comprised personnel associated with activity at the company office, and the underground operations and processing area accessed from Baxter Road. The majority of underground mine activity is a 24-hour operation and is undertaken by shift workers. Typically, there are two shifts per day which start at around 7 am and 7 pm respectively. Open pit work was typically a daytime-only operation. The consented hours of work are 7 am to 7 pm weekdays and 7 am to 12 pm Saturdays. OGNZL has provided historical gate log data for Baxter Road (2008 to 2013 inclusive) which identifies the number of vehicles entering each gate. This gate data has been used in combination with the personnel records to understand both historical and forecast traffic demands associated with the mine. At the Baxter Road access, the average daily number of inbound vehicles at the Baxter Road gate is summarised in Figure 27. Figure 27: Average Daily Inbound Traffic at Baxter Road Gate The data shows that light vehicle movements account for around 90% of all vehicle movements on Baxter Road. The busiest period is mid-2011 to early 2012 which corresponds to the period of peak workforce levels shown in. 4 Project Martha (Consented) There are numerous previously granted consents relating to the Waihi mining operation, the most recent of which was Project Martha which is intended to extend the life of the mine.
