Rumble Resources Ltd. was founded in 2011, and it is an Australian mining company headquartered in West Perth, Australia. It has been publicly traded on the ASX under the ticker RTR, so it was definitely traded as a listed company.

Ownership

Publicly available sources in this search did not give a simple “owned by X” answer, because Rumble Resources is a listed company with shareholders rather than a single private owner. The company’s website describes it as 100% Rumble owned for some projects, which refers to project ownership, not the whole company’s corporate ownership.

Trading history

The company has been traded on the Australian Securities Exchange, and recent market news still refers to it as ASX:RTR. That means the company itself remained publicly listed during the period covered by the sources.

Name change

The name-change result I found is for a different company called Rumble Resources Inc. , which changed its name to NovaRed Mining Inc. in February 2026 to avoid confusion with other public companies with similar names. That is not the same as the Australian ASX company Rumble Resources Ltd., so the reason for a name change does not appear to apply to RTR from the sources I found.

What this means

  • Started: 2011.
  • Owned by: public shareholders, not a single private owner in the sources I found.
  • Traded: yes, on the ASX as RTR.
  • Name change: the available name-change explanation belongs to Rumble Resources Inc., not the ASX-listed Rumble Resources Ltd.

If you want, I can next separate the ASX company history from the Canadian company history in a clean timeline.
