The two developers own 50.1% and 49.9% of the project respectively.
The pair said they have applied for an additional 148 square kilometres of ground that forms a close-fitting inner ring around the Ballarat mine and which became available on Monday.
The new application covers ground surrounded on all sides by RRAL's existing licence applications, which amount to 2,336 square kilometre of ground in the Victoria Gold Fields.
Three other parties have also applied for licenses covering the ground, which the miners said demonstrates the strategic significance of this area.
RRAL has received several approaches from third parties to acquire interests in, joint venture or earn-in to the RRAL license package, in whole or part.
Alongside the intention to list some or all of RRAL on a North American stock exchange RRAL is working with potential partners to assess external proposals, it added.
The firms continue work on equipping and staffing its headquarters office in Ballarat, in Australia, and on technical planning for anticipated exploration and drilling programmes.
“As a Ballarat-based company with its focus on Ballarat, we consider that this ground would be a logical fit with our holdings in the area and enable us to further our mission of becoming a Ballarat specialist,” Red Rock’s chairman Andrew Bell commented in a release.
“There is an intense level of activity around RRAL demonstrating a commitment to building a rapidly growing Australian gold company focused on the Victoria Gold Fields,” Power Metal’s chief executive Paul Johnson said in a separate announcement.
