Larvotto Resources (ASX:LRV) modified plans at its Hillgrove Antimony-Gold Project in New South Wales to implement dry stacking of process tailings, replacing the previously planned larger conventional wet slurry facility, according to a Monday filing with the Australian bourse.

The New South Wales government has approved the change as a modification to the existing project permit, the filing said.

The switch to dry stacking reduces engineering risks, simplifies permitting, and improves landform rehabilitation during operations, the filing added.

Additionally, the change streamlines the permitting process, with no impact on the project's startup costs, the company said.

The transition to dry stacking will allow Larvotto to rehabilitate tailings landforms during the life of the project, rather than only post-completion, and apply best practices to legacy tailings areas.

The modification is being integrated into the ongoing definitive feasibility study, expected to be completed in the first quarter of fiscal 2025, the company added.

Shares of the company fell past 2% in recent Monday trade.
