It appears Shane Jones has not been listening.
In his opinion piece he accuses Pakeha with environmental concerns about mining of trying to undermine hapu development aspirations. He's missed the point, not all mining techniques are equal. For example, mining limestone and aggregate within his own rohe would not create toxic waste.
Legitimate concerns being raised are on mining techniques that leave toxic waste. I would expect all MPs and councils to take this seriously instead of blindly rolling on with corporate economic development speak.
The type of rocks that hold gold and silver in the North means its extraction would create millions of tonnes of toxic waste that would most likely end up stored at the top of water catchments.
How? The gold-baring rocks would be crushed to a powder, flooded with cyanide which separates out the gold and silver. This chemical process using cyanide also changes the nature of the remaining heavy metals in the rock and makes them "bioavailable".
