From observations made during the inspection of the site no adverse environmental effects were found, or

achieved either an ‘excellent’ or a ‘good’ grading across the 2016 to 2021 period, with all
but one day of the remaining 4% falling into the ‘Acceptable’ category.

abstraction
The Company monitors the volume of water abstracted. Groundwater level monitoring was instituted as a
requirement of consent 9608-1.2, held by DR Wilson for abstraction of groundwater at a location across the

storm pond. The stormwater falling on the non-process areas of the western half of the site (Figure 1) is
directed by “v” ditches running alongside the roads to a dam/pond and then out to the Tasman Sea via the
Manu Stream. Stormwater falling on the eastern side of the site is directed to unnamed tributaries of the
Waihi Stream via outfalls and a small sedimentation pond.

* The productive class is defined by River Environment Classification (REC) types, with a combination of dry climate categories
and soft-sedimentary, volcanic acidic and volcanic basic geology. All sites that do not fall in these categories are in the default
class.
