Montero Strengthens Technical Team to Advance the Mineral Processing and Hydrometallurgical Work on Ore from the Wigu Hill Rare Earth Project in Tanzania

TORONTO, ONTARIO--(Marketwire - Dec. 13, 2011) - Montero Mining and Exploration Ltd. (TSX VENTURE:MON) ("Montero") has assembled a highly experienced team of mineral processing and chemical engineers including Geoff Skelton, former head of development at the Impala Platinum hydrometallurgical refinery and Richard Amata, former Senior Chemist with Molycorp Minerals Inc. The team is comprised of in-house employees and consultants to support the development of a rare earth metals separation refinery to process ore material from the Wigu Hill Rare Earth Element Project in Tanzania.

Dr. Tony Harwood, President and Chief Executive Officer of Montero commented, "Montero's new engineering team will lead and support Mintek's Mineral Processing and Hydrometallurgical optimization process to a feasibility study and eventually construction of a process plant and refinery operation. The team have a proven track record in minerals processing and hydrometallurgical test work, process design, feasibility, construction and production operations and will be key in achieving our plan to fast-track mining and production of rare earths from the Wigu Hill Project in Tanzania. Securing the right team to fast track development of the mine and refinery is a crucial step towards production at Wigu Hill."
The team will be headed by:
  • Geoff Skelton, an Industry recognized hydrometallurgist with over 30 years of experience in Base and Precious metals hydrometallurgical plant design and operations in South Africa. Geoff graduated with a B.Sc. (Hons) Chemical Engineering from the University of Exeter, UK. He spent 21 years with Impala Platinum Refineries filling roles including General Manager and Project Manager where Geoff was responsible for the metallurgical development of state of the art hydrometallurgical separations processes that are incorporated within Impala's Enhanced Precious Metals Refinery in Springs, South Africa.

About Montero Mining and Exploration

Montero Mining and Exploration Ltd. is a mineral exploration and development company engaged in the identification, acquisition, evaluation and exploration of mineral properties primarily focused on rare earth elements (REE), phosphates and uranium in Tanzania, South Africa and Quebec, Canada respectively. Montero is focused on adding value through the acquisition and exploration on properties, which have the highest potential for future discoveries or development of existing mineral resources into mineable reserves. We remain engaged in the development of our flagship Wigu Hill Rare Earth Element Project in Tanzania, which is a high-grade, undeveloped Light Rare Earth Element deposit. The Company's current focus is on updating the initial NI 43-101 Mineral Resource Estimate and advancing hydrometallurgical testwork with Mintek. With the rising prices of REEs and China's control over export quotas, it is becoming imperative that the rest of the world develops new rare earth resources to meet the increasing demand from "green" technology and high-tech applications.

Montero's growth strategy is to develop the Wigu Hill Rare Earth Element project and to bring this to account through eventual rare earth production and cash flow, while operating in an environmentally and socially responsible manner. We will continue to add value for all stakeholders through the development of our portfolio of properties. Montero trades on the TSX Venture Exchange under the symbol MON.
