ASX-listed St Barbara has announced an initial project description (IPD) for its planned 15-Mile Processing Hub project, in Nova Scotia, which has been submitted to the Impact Assessment Agency of Canada (IAAC).

In fact, the agency already confirmed the IPD's passing through its conformity review stage, which will now be followed by IAAC sharing the IPD with the public and First Nation communities.

Subsequently, the IAAC will decide whether an impact assessment is necessary.

The IPD submission will leverage the recently signed cooperation agreement between the governments of Nova Scotia and Canada to work toward efficiently and effectively implementing the 'one project, one review' process.

The IPD submission triggers the formal planning phase for the project, with St Barbara continuing to advance studies to align with other planned submissions, such as EARD, by the third quarter of the 2027 financial year.

St Barbara confirms that the 15-Mile Processing Hub is being designed to incorporate feedback from First Nation communities, local stakeholders, regulators and environmental experts, while taking into account three years of improvements made during engineering and trade-off studies.

St Barbara MD and CEO Andrew Strelein elaborates that this IPD submission marks a major milestone in advancing the project to approval. The IPD submissions also reflect nearly three years of work to redesign and strengthen the project design to incorporate feedback received from all stakeholders, which will result in a project that is both more acceptable and more beneficial for the communities.

The 15-Mile Processing Hub will consist of the redevelopment of three historic mining sites in Nova Scotia. The 15-Mile mine alone consists of four openpits, the relocated Touquoy processing facility and associated infrastructure such as a tailings management facility.

The Old Austen and Old Mitchell mines, in turn, both comprise only single quarry-style projects.

The 15-Mile Processing Hub will be the sole processing hub for ore from the three mines, with an expected processing capacity of three-million tonnes a year.
