MON Montero Mining and Exploration Ltd

Montero Mining and Exploration Ltd. (TSX VENTURE:MON) ("Montero") provides an
update on test work performed on the bastnaesite-rich carbonatite material from
the Wigu Hill Rare Earth Project in Tanzania. A metallurgical study was
completed by SGS-Lakefield in Canada examining flotation processes to upgrade
Rare Earth Element ("REE") minerals from the Wigu Hill bastnaesite-rich
carbonatite material. 


The purpose of the study was to identify a processing route that could recover
the rare earth bearing minerals while rejecting major gangue minerals which
include; strontianite, dolomite, quartz, and barite. In laboratory scale test
work, flotation tests were completed to evaluate various collector types and
dosages. The best results from rougher stage tests were achieved from a head
grade of 6.42% Ce2O3 using a hydroxamate-type collector. Here, the cumulative
rougher concentrate graded 12.8% Ce2O3, with 79.1% recovery and 48.1% mass pull
which represents x2 upgrade. A collector was also selective against barite,
quartz, Fe-oxides, and dolomite. The results achieved in the scoping study
demonstrate the potential to recover REE minerals into a pre-concentrate and
reject the major gangue minerals, which are acid consumers for the downstream
hydrometallurgical process.



                                                                           
 Dr. Tony Harwood, President and Chief Executive Officer of Montero         
 commented, "Advancing the mineral processing flowsheet with the flotation  
 testwork completed by SGS-Lakefield, keeps us on a production focused      
 target for our flagship Wigu Hill project. These positive results represent
 a significant step in advancing the beneficiation process and improving    
 Montero's economic flowsheet for the extraction of REEs from the           
 bastnaesite-rich carbonatite mineralization. By reducing downstream reagent
 consumption costs we are on track to becoming a low cost producer of Rare  
 Earths."                                                                   



The report from SGS-Lakefield, an internationally recognized metallurgical
research and test work facility in Ontario Canada, will form the basis for
further laboratory and pilot scale test work in which flotation, as a mineral
processing option, will be further explored and optimized.

About Montero Mining & Exploration 

Montero Mining and Exploration Ltd. is a mineral exploration and development
company focused on achieving production of rare earths primarily from its
flagship Wigu Hill project in Tanzania. With China's control over rare earth
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 has a highly experienced Board and Management
team that has built and operated mines and refineries in Africa, which brings
significant credibility to our strategy of becoming a rare earth producer. In
addition to rare earths, Montero has phosphate assets in South Africa and
uranium assets in Tanzania and Quebec, Canada for sale or joint venture.
