Killi Resources (ASX:KLI) said a second drill rig arrived at the Lodestone project in Western Australia to advance the resource growth and drilling program that started in August, according to a Thursday filing with the Australian bourse.

The reverse circulation rig will work with the diamond core rig on site to focus on both the northern and southern extensions to the current resource, as well as depth extensions within the 25-kilometer-long magnetite system, the filing said.
