Minerals 260 (ASX:MI6) said it started early construction and development activities at its fully owned Bullabulling gold project in Western Australia, according to a Monday filing with the Australian bourse.

The company said it is progressing work on multiple fronts, including village construction, water infrastructure, and grade control drilling. It plans to start plant construction in the first half of 2027 and is targeting first gold production at the project in the fourth quarter of 2028.

The project's maiden ore reserve and pre-feasibility study remain on track for July, ahead of an updated mineral resource estimate planned for August, per the filing.

Minerals 260 said it ended the March quarter with around AU$250 million of cash and deposits, leaving it well positioned to continue Bullabulling's development.
