About Montero Mining & Exploration

Montero Mining and Exploration Limited is a mineral exploration and development company focused on the development of our flagship Wigu Hill Rare Earth Element Project in Tanzania. The Wigu Hill project is a high grade undeveloped Light Rare Earth Element deposit where the company's current focus is on reporting an initial NI 43-101 compliant resource on the first two of ten drill target areas tested to date.

Rare Earth Elements (a group of 15 metals) are critical in the advancement and development of emerging "green" technologies and high-tech applications such as electric and hybrid vehicles, wind and hydro power turbines, energy efficient lighting, LCD screens, MRI, X-ray machines and neodymium-based magnets crucial to ear-buds, MP3 Players, microphones, mobile devices and other computing equipment. Currently China produces 97% of world supply of REE's and these are becoming increasingly critical to both 21^st Century technological progress and environmentally sustainable development. With the rising prices of REE's 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.

Montero's growth strategy is to develop the Wigu Hill Rare Earth Element project and to bring this to account by eventual rare earth production and cash flow. Montero plans to operate in an environmentally and socially responsible manner, adding value to all stakeholders. Montero has 42,365,730 shares outstanding and trades on the TSX Venture Exchange under the symbol MON.
