Montero Mining and Exploration Ltd. has received results of the remaining infill diamond drill holes completed on the Twiga Zone on the far eastern edge of the Wigu Hill Rare Earth Project in Tanzania. The Twiga Zone makes up a portion of the existing NI 43101 3.3Mt Inferred Mineral Resource Estimate. None of the infill drill results in this release were included in the resource with the exception original near surface drill holes TW001, TW002 and TW003R. The infill drilling program consisted of 17 core boreholes (900 metres), which were drilled at approximately 25 metre spacings and down to an average inclined depth of 35 metres. The results of one hole, TW016 has already been reported and is very positive at 7.35% TREO over 11.5 metres. At the eastern end of the main 'EastWest' dike, northwest trending bastnaesiterich dikes were intersected in Boreholes (BH) TW021 and TW030 in which very encouraging TREO mineralization was located. The tonnage potential is quite significant in this area from a number of subparallel mineralized carbonatite dikes, which have been cut by nearby trenches or boreholes drilled from the NE. The dike thicknesses increase from 2.19m in BH TW018 to 20.74m in BH TW003. Thicknesses are variable between 7.13m and 14.50m true thickness in a SW direction to BH TW028 where a near surface intersection is 3.08m at 11.36% TREO. The drilling data and geological evaluation of the Twiga Zone is being modeled with a view to outlining an ore resource at an increased confidence level, which will provide an update to the NI 43101 Resource Estimate released in September 2011.
