Wildlife deaths, intergenerational harm flagged in gold mine assessments

Gold Mine Proposal Sparks Fierce Debate: Wildlife, Heritage, and Economy Clash Near Cromwell

A controversial gold mine proposal near Cromwell is igniting a firestorm of debate, pitting significant economic promises against grave concerns for the region's unique environment and rich cultural heritage. The Bendigo-Ophir project, put forward by Australian company Santana Minerals, has drawn strong opposition from a broad coalition of environmental groups, local iwi, and residents, while also garnering support from some landowners and a dedicated community group. A decision on the mine, which involves four open-cast pits, is expected from an expert panel by October.

Santana Minerals has presented the project as a major economic boon for New Zealand, projecting it could create hundreds of jobs, generate $6 billion in export revenue, and contribute over $1 billion in taxes and royalties. The company asserts that the application is the culmination of years of meticulous technical and environmental assessments.

However, these claims are being met with significant skepticism. The Department of Conservation (DOC) has issued a stark warning, estimating that the mine could lead to the deaths of as many as 600,000 native lizards. The Otago Conservation Board has also flagged serious risks, highlighting that the proposed tailings storage facility could attract wetland birds to water contaminated with toxic cyanide. Both DOC and the Otago Conservation Board have recommended that the expert panel decline the consent.

Fish & Game Otago echoed these concerns, stating that there is insufficient evidence to guarantee the protection of trout and game birds from potential contaminants. Gary Taylor, chief executive of the Environmental Defence Society, described the environmental impacts as "completely over the top," arguing that the mine is "the wrong mine in the wrong place." He believes a "tsunami of expert evidence" is contesting the application, which should be enough for the panel to reject it.

The Parliamentary Commissioner for the Environment, Simon Upton, has also weighed in, characterising New Zealand as an "immature mining destination" lacking the robust standards found in countries like Canada or Australia. He stressed that the panel must be able to independently verify that risks will be mitigated for at least a century after the mine's closure, or decline the application. Santana Minerals was due to provide its response to these comments by Friday.

Economic Diversification: A Ray of Hope for Some

Despite the widespread environmental opposition, the Bendigo-Ophir project has found vocal supporters. The New Zealand Minerals Council, Shine Irrigation Company, two neighbouring landowners, and the Santana Mine Supporters community group have all backed the proposal.

Bill Sanders, a Cromwell local and head of the Santana Mine Supporters group, claims a substantial and informed segment of the local population supports the mine. His group has reportedly grown to 8,600 members, many of whom view the mine as a crucial opportunity for economic diversification in Central Otago.

"In Central [Otago] at the moment the cherry orchards and the vineyards, they're not having a very good time of it," Sanders explained. "So here's an opportunity for people to get a decent job in the mine and let's not forget that the mine won't be the only thing. There'll be downstream industries where people will be able to work and earn good money in those as well." He expressed confidence in the mine's future oversight and assured that it would only be approved if it met stringent standards, highlighting that modern mining practices are significantly cleaner and that the company's management is highly experienced.

However, not all community groups are convinced. Sustainable Tarras, another local collective, opposes the project, citing overwhelming adverse impacts. The group claims over 9,000 people have signed up to their email list in opposition. Suze Keith, chair of Sustainable Tarras, voiced primary concerns about the contamination of surface and groundwater, noting the difficulty of reversing aquifer contamination once it occurs. She also stated that the project's suitability for fast-tracking was questionable, suggesting that the gold could have remained in the ground while Santana pursued the standard Resource Management Act process.

Mana Whenua and Heritage Concerns Loom Large

The cultural and archaeological significance of the proposed mine site has also become a major point of contention. Kuma Southern Māori Business Network has alerted the panel to insufficient recognition of wāhi tapu (sacred sites) and the risk of disturbing kōiwi (human remains) through large-scale excavation.

Kā Rūnaka has argued that granting consent would be unlawful, as it would conflict with the Ngāi Tahu Treaty Settlement and potentially inflict intergenerational harm.

Neighbouring landowners have also voiced opposition, with some reporting a significant drop in property values. One family fears their homestead and farming infrastructure are in a "red zone" where a tailings dam failure could lead to extensive toxic inundation. Another resident complained that their once-quiet rural road has already become a "dust bowl" due to increased Santana traffic.

Heritage New Zealand has also criticised Santana Minerals, stating that the company has downplayed the existing heritage values of the project area and underestimated the potential adverse effects. They warn of an "almost total loss of heritage values within the footprint of the mining operation."

Councils and Ministers Weigh In

The Otago Regional Council (ORC) and Central Otago District Council (CODC) have not taken a definitive stance for or against the mine but have raised concerns about its environmental risks. The ORC's geotechnical consultants have found that the proposed tailings storage facility currently does not meet stability standards. The CODC has noted that the project's proposed noise and vibration activities would necessitate additional land-use consents.

Six ministers have provided feedback on the project. Māori Development Minister Tama Potaka is the only minister who has explicitly stated his support for the application. Infrastructure Minister Chris Bishop expressed "broad support for projects which deliver positive outcomes for New Zealand, including the Bendigo-Ophir Gold Project," while South Island Minister James Meager highlighted the project's "substantial economic benefits" for the region. Regional Development and Resources Minister Shane Jones indicated that the project aligns with the Minerals Strategy for New Zealand, which aims to double mineral export revenue by 2040.

Santana Minerals' Response

In a statement, Santana Minerals chief executive Damian Spring indicated that the company would address all feedback through its submission to the panel. He emphasised that the project is supported by extensive technical work undertaken by independent experts over several years.

"The project is backed by a substantial body of technical work developed over several years by independent experts and that material is now being examined through the process," Spring stated. "It's not appropriate to address individual points in isolation - the legal framework is designed to assess all questions against the full evidence base. Our focus is on engaging directly through the process and providing comprehensive responses to the panel."

The complex web of environmental, cultural, economic, and social considerations surrounding the Bendigo-Ophir Gold Project ensures that the expert panel faces a monumental task in reaching its decision. The outcome will undoubtedly have lasting implications for the future of the Central Otago region and New Zealand's approach to resource development.
