Tanzanian Royalty Reports That Laboratory Results Confirm Widespread Distribution of Diamond Indicator Minerals From Three Projects in Tanzania

    Vancouver, Canada (ots/PRNewswire) - The Company is pleased to report that a wide range of kimberlite indicator  minerals has been identified on three of its diamond projects in Tanzania.  Kimberlite is the host rock for most of the world's major diamond deposits including the Williamson diamond pipe at Mwadui, Tanzania, the largest ever  mined.

    "Visual identification of the indicator minerals from these three project areas has also confirmed the presence of numerous chrome diopsides,  a mineral that is often associated with diamondiferous kimberlites," noted  the Company's Tanzania-based president, John Deane.

    "A selection of kimberlite indicator minerals from these areas will be  subjected to electron micro-probing to determine their mineral chemistry  and results from this laboratory work should be available in the next  quarter," he added.

    All indicator mineral analysis is being conducted by Mineral Services  in Cape Town, South Africa. Twenty five kilogram samples (55 lbs) were  submitted to Mineral Services for analysis from each hole in last year's  Rotary Air Blast (RAB) drill program.

    A recap of the drill program and the analytical results reported by  Mineral Services are presented below on a property-specific basis. Please  note that the same nomenclature (i.e. K1, K2......) is used to identify the  various kimberlite bodies on each property even though they are different  pipes.

    Mwadui Project Area: Nyamigunga PL

    The Nyamigunga PL is known to host five kimberlites within an area of  approximately two square kilometres. In actual fact, these kimberlite  bodies represent a "cluster" or assemblage of carrot-shaped pipes which  were likely intruded along some regional structure that provided a pathway  to surface for diamonds and their associated kimberlite indicator minerals.

    The five kimberlites were first tested more than 20 years ago by the  Madini-Mwadui partnership, a joint venture between the Tanzanian government  and DeBeers, the world's largest diamond mining and trading organization.

    In the early 1980s, 450 tonnes of surface gravels and two tonnes of  kimberlite were processed through a small wash plant, yielding several good  quality diamonds. "With diamond prices at historically high levels, these  previously assessed situations are certainly worth revisiting," said Deane,  adding: "Of particular interest to us is the potential to identify any  local hard rock source for these diamonds."

    Ground magnetic surveys were completed on these licenses in September  of 2005, identifying two new untested targets that were subsequently tested  by RAB drilling in November. All five kimberlite bodies were intersected in  the program and two previously undiscovered pipes were found after drilling  two untested magnetic anomalies. Visual results from Mineral Services were  received in March 2006 and they are very encouraging as indicated in the  table below:

      K1 pipe:
            Chromite:                  132 grains
            Chrome Diopside:         30 grains
      K2 pipe:
            Purple Garnet:          189 grains
            Orange Garnet:            55 grains
            Chromite:                  106 grains
            Chrome Diopside:         62 grains
      K3 pipe:
            Purple Garnet:              5 grains
            Chromite:                      8 grains
            Chrome Diopside:          1 grain
      K4 pipe:
            Chromite:                      2 grains
            Chrome Diopside:          7 grains
      K6 pipe:
            Chromite:                      4 grains
      K7 pipe:
            Chromite:                      2 grains

    Poor ground conditions including heavy water inflows may have produced  contamination in the drill holes which could explain some of the low grain  counts in several pipes. Nevertheless, kimberlite bodies within Tanzania  often have variable indicator mineral chemistry without diminishing their  economic potential.

    Igunga Project Area

    Two brand new kimberlite pipes were also discovered in the Igunga Project Area in November 2005. One RAB hole penetrated 67 metres of lake  profile overburden before intersecting kimberlite K1 from 67 to 82 metres.  A second hole penetrated 83 metres of similar material before intersecting  kimberlite K2 from 83 to 102 metres. Both holes were terminated in  kimberlite after the Company successfully recovered 25 kilogram samples for  laboratory analysis. Further exploration will be required on these  kimberlites to determine their geometric configuration and depth potential.  Visual results from Mineral Services for these pipes are highly encouraging  as shown below.

      K1 pipe:
            Purple Garnet:          1 grain
            Orange Garnet:          1 grain
            Ilmenite:                 58 grains
            Chromite:                 19 grains
            Chrome Diopside:      27 grains
      K2 pipe:
            Purple Garnet:         75 grains
            Ilmenite:                 52 grains
            Chromite:                 54 grains
            Chrome Diopside:      35 grains

    Nzega Project Area:

    Two new kimberlite pipes were also discovered in this area, both of  which were internally generated geophysical targets. One pipe occurs close  to artisinal diamond activity for alluvials in a nearby river bed. "This  suggests that these kimberlite pipes - or others nearby - may be the  primary source of the diamonds in these alluvial workings," said Deane.  Visual results from Mineral Services include the following kimberlite  indicator minerals.

      K1 pipe:
            Orange Garnet:          1 grain
            Ilmenite:                 22 grains
            Chromite:                  5 grains
            Chrome Diopside:        1 grain
      K2 pipe:
            Orange Garnet:        106 grains
            Ilmenite:                 40 grains
            Chromite:                 63 grains
            Chrome Diopside:      45 grains

    Confidentiality Agreements

    The Company also wishes to announce that several companies have either  expressed an interest in or in fact have signed Confidentially Agreements  (CA's) with respect to certain properties owned by the Company in the Lake  Victoria Greenstone Belt of Tanzania.

    These agreements include gold and diamond prospects that are at various  stages of exploration. Under these agreements, interested parties have the  right to review technical data on the properties but they are not allowed  to share the information with others who are not party to the agreement.

    "I take great pride in the numerous accomplishments of our management  team and the competence, drive and successes of our exploration group which  is now being recognized by the growing number of Confidentiality Agreements  that are now in place or under consideration," said the Company's Chairman  and CEO, Jim Sinclair. "With the largest exploration undertaking on the  African Continent, I look forward to more announcements of progress for our  investors and potential industry partners."

    Mineral Services Disclaimer:

    Results from examination of concentrate are reported on the basis of  possible kimberlitic indicators recovered by visual inspection of concentrate under a binocular microscope by experienced mineral sorters.  Mineral classifications are reported on the basis of visual identification  unless otherwise specified. Such visual classifications may be inaccurate  and are provisional until confirmed by analysis.

    The Company's Qualified Person is Mr. John Deane, the President of Tanzanian Royalty Exploration, M.Sc. University of Cape Town (1993), a  registered scientist with SACNASP (Reg. No. 400005/05).
