Waihi North Project – Overview of Application Structure viii GLOSSARY OF TERMS Term Meaning Alimak A proprietary mast climbing (rack and pinion) access system developed by Alimak Group AB (Sweden; https://alimak.com/new-equipment/) that has been adapted to facilitate bottom-up underground shaft construction. Area 1 Means Area 1 as shown on Figure 4 in the Overarching AEE. Area 2 Means Area 2 as shown on Figure 4 in the Overarching AEE. Area 3 Means Area 3 as shown on Figure 4 in the Overarching AEE. Area 4 Means Area 4 as shown on Figure 4 in the Overarching AEE. Area 5 Means Area 5 as shown on Figure 4 in the Overarching AEE. Area 6 Means Area 6 as shown on Figure 4 in the Overarching AEE. Area 7 Means Area 7 as shown on Figure 4 in the Overarching AEE. Average Return Interval The average time period between rainfall or flow events that exceed a given magnitude. Benthic Of, relating to, or occurring at the bottom of a body of water. Canopy Tallest layer of the forest. Catchment An area of land bounded by natural features such as hills or mountains from which surface water flows into streams, rivers and wetlands. Central Stockpile An existing stockpile, located adjacent to the existing TSFs, used for the disposal of rock material. Concrete Batching Plant Existing infrastructure, located north of the conveyor and immediately west of the WTP, that produces cement aggregate fill for use in the backfilling of underground mines. Construction Runoff Any runoff, sediment laden or otherwise, that flows as a result of the construction related activities. Typically results from rain events. Collection Ponds A pond for the purpose of gathering and retaining run-off water for treatment in the WTP. This may include settlement, treatment, and interception/removal of hydrocarbons. Contact water Is water that has contact with mining, mineral processing, and tailings disposal and, as such, is not suitable for direct release into the environment. Construction works Various activities undertaken to construct the Waihi North Project. Contingency Ponds Ponds which collect runoff from the ore stockpiles and conveyor, while also providing containment of any chemicals used for processing ore and water treatment in the event of spillage. These ponds will remain active until mine closure.
