I have had a look through Google Earth to see if the mining permit to the immediate east of GEL's Waikaia permit shows any action. It was reported as being underway in February this year. The satellite image must be old, as it shows no disturbance to the paddocks there at all.

The GEL report says that there appeared to be no disturbance to the gravel and sediment layers wherever they drilled on the east side of their permit. The Kaipara/Solway drill research concentrated in a narrow strip heading North to South right beside McDonald Road. Where GEL's permit tucked into the bottom end of this channel, they have spent a fair bit of effort getting drills done there, and they have been relatively high grade. One cross-section that was provided implies that there are two wash layers a small distance apart, which merge as you get closer to the Garvie Burn (stream). However the Garvie Burn stream must have been heavily dredged years ago, and the hills to the east of there look to have been sluiced in many places.

Glass Earth has a permit over an unworked area.

Travelling a bit further northwards, Google Earth has been updated in the Drybread area. A bit of cloud there on the day in question, but take a look at the earthworks. They really are mining over there!
