Rose Petroleum plc

Mineral Assets

With the Company’s focus now on U.S. oil resource plays, the strategy for the legacy mining assets is to maximize shareholder value with little to no further capital investment.  

The Company has interests in base and precious metals and uranium.  The base and precious metals projects are located in Mexico and the USA.  In Mexico, the Company owns and operates a floatation mill and leach facility and operations center on projects that can generate cash from production to fund the Company’s exploration and development program. The Tango base-metals porphyry project is held by agreement that also covers gold and silver projects which are part of the same porphyry system. In the USA, the Company is focused on the southwestern USA porphyry-copper province.  The Company’s uranium holdings are located in Arizona and Utah.

The mining assets are held and operated by the following wholly owned Rose subsidiaries:

  • Minerales VANE SA de CV – Mexico base and precious metals projects
  • AVEN Associates LLC – USA base and precious metals projects
  • VANE Minerals (US) LLC – USA uranium projects
