Montero presents at Byron's electric metals conference

  1. 1. Focus on exploration for Rare Earth Elementsand associated minerals
  2. 2. Disclaimer 2
  3. 3. Montero - Company Background • listed on the TSX-V (MON) February 2011 • focused on rare earth elements • ex Placer Dome team • Share Price C$0.77, Market Capitalization C$32.6M Shares as at April 11, 2011 (million) Shares issued 42.3 Stock options 3.7 Warrants 7.1 Total – fully diluted 53.1 Director and officers 15.49% 3
  4. 4. Wigu Hill Project – Overview• Ownership • 60% ownership - option to 100% with Tanzanian JV partner• World-class deposit • large carbonatite complex (6.4km x 3.2km) intruded by sheeted high grade bastnasite bearing dykes • first identified in 1957, historic grades up to 16.5% TREO • high grade identified by Montero 27.25% TREO• Development potential • 170km south west of major port of Dar es Salaam • 12km to Tazara rail linking Zambia and Dar es Salaam • Good infrastructure, water, transport and mining support • High grade, large tonnage open pit potential• Tanzania – mining friendly country • Good mining law with major mining companies operating 4
  5. 5. Wigu Hill Project Location Wigu Hill licences –142km² Dar es Salaam 5
  6. 6. Wigu Hill – Drill Targets Tembo drill Twiga drill target target NPrevious mapping and sampling programs defined 10 drill target areas 6
  7. 7. Wigu Hill – Location of Drill Targets 7
  8. 8. Rare Earth bearing Carbonatite Dykes The carbonatite dykes consist of finely to coarse crystalline dolomite with minor amounts of goethite and intergrowth of Bastnasite bearing Burbankite crystals. Hexagonal burbankite hosts abundant bastnasite and related rare earth minerals, plus barite strontianite, quartz and dolomite. 8

  14. 14. Wigu Hill – BH TW0001 Bastnasite-Rich Intersection 14
  15. 15. Wigu Hill Mineralogy• Simple REE mineralogy predominantly: Bastnasite Synchisite LREE* (CO3) F Ca LREE* (CO3)2 F Density: 4.7 to 5.0 Density: 3.9 to 4.0 Hardness: 4 to 4.5 Hardness: 4 to 4.5• Occur as course crystalline aggregates intergrown with barite, strontianite and Fe-dolomite; REE, Ba, Sr minerals replace earlier minerals 15
  16. 16. Mintek – Montero Metallurgical ResearchMintek commissioned to develop a rare earth element (REE)extractive process flow sheetJoint team to design a process flow sheet to maximise recoveriesof REO’s and determine process economics to yield: High purity mixed rate earth oxide (MREO) concentrates; and Individual pure rare earth oxides (REOs).Mintek has worked for over 25 years on REE metallurgy, haspatented treatment processes for REE production andsuccessfully run pilot plant scale operations.
