“We are pleased to have crossed this threshold,” said EDS CEO Gary Taylor.

“The project comprises four open pits and underground mining, associated processing infrastructure and a very large tailings dam in the Dunstan hills above the Clutha River in central Otago.

“Ever since it was listed in the Fast-track Approvals Act we have been investigating its potential environmental effects and testing its purported economic benefits.

“The Applicant has spent millions preparing an extensive case, totaling over 9,000 pages of legal and technical reports. It says that the regional and national benefits of the project outweigh environmental and other adverse impacts.

“Our invitation to join the process means that we can provide the decision-making Panel with independent expert evidence scrutinising these assertions.

“EDS has a long track record of bringing evidence-based environmental analysis to major decisions. For this case, we have engaged senior counsel and independent specialists, including experts in economics, terrestrial ecology and freshwater. Our evidence will critically evaluate the project’s economic benefits and the environmental risks.

“Our analysis to date identifies material environmental impacts and overstated economic benefits.

“We are extremely grateful to those that have donated to support our case so far. We still have a shortfall of $40,000. If you’re able to assist with this remaining cost, please contact shay@eds.org.nz.

“As part of our involvement in this matter EDS has also made a submission to the Overseas Investment Office on the applicant’s proposed purchase of the site, and we are scoping the decisions made by the Central Otago District Council to grant roading access.

“EDS has until 10 April to present its case to the Panel,” Mr Taylor concluded.
