Energy Resources of Australia (ERA) has decided to scrap its proposed Heap Leach Facility at the Ranger Mine in the Northern Territory.

The company revealed the decision in its half-year results, which were released today.

The proposed facility was designed to process low-grade uranium ore in stockpiles at the mine, located inside Kakadu National Park.

ERA says it decided not to proceed with the project because of high capital costs and an uncertain level of support from stakeholders.

The half-year results also show a net loss for the company of about $122 million.

ERA blames the result on the suspension of operations at Ranger for six months because of the wet season.

The company says it plans to cut operational costs by $150 million over the next three and a half years.

But it says it is still pursuing its 3 Deeps project, a proposed underground mine which would be established just north of the Ranger site.
