Tsodilo Resources Limited Announces Positive Micro-Diamond Results
TORONTO, CANADA - Tsodilo Resources Limited (TSX Venture Exchange: TSD) ("Tsodilo" or the "Company") is pleased to announce positive results of caustic fusion analyses of micro-diamond samples by the Saskatchewan Research Council ("SRC") from kimberlites K4 and K10.

To date, 27 kimberlites that have been identified in the Nxau Nxau province which stretches over an area of some 40 by 25km oriented in a NW-SE orientation. An analysis of the technical characteristics of the known kimberlites in the Nxau Nxau field was initiated in 2010. Additional mineral chemistry and petrography work was necessary for some of the kimberlites and this was completed in late 2010. A review of this data resulted in the decision to submit samples from three kimberlites (K4, K10 and K20) for micro-diamond analysis, in order to conduct a first-pass evaluation for these bodies. Micro-diamond work had previously been conducted on six kimberlites in the Nxau Nxau field resulting in the recovery of a singleton diamond from three and two diamonds from one of them. A review of the methodology of this work was not regarding as qualitative.

Approximately 200kg of drill core from each of K4, K10 and K20 were submitted for analyses to the SRC laboratory in Canada in 2010 and results were recently provided. All holes were drilled using HQ size core utilizing synthetic diamond drill bits. Two of the three kimberlites submitted for analysis had positive micro-diamond recoveries as follows:

The most interesting result was obtained from kimberlite K10 which returned 14 stones from 221.2 kg or 63.3 stones per ton (SPT). This is the first time that such number of micro-diamonds had been returned from any of the kimberlites in Ngamiland. The recovered diamonds appear to be colorless and fragmented and can be viewed on the Company's website at: /s/K4andK10.asp.

Inclusive of this recent testing, seven kimberlites out of a cluster of 27 intrusions have been tested for micro-diamonds. Of these, four tested positive for micro-diamond with one, K10, significantly so. These recent results in combination with previous micro-diamond analyses, indicates that the province is clearly diamondiferous. Kimberlite K10 has been classified as poorly sorted coarse-grained re-sedimented volcaniclastic (RVK) kimberlite and is interpreted as a bedded crater-facies kimberlite. Although the crater has not been well-defined, the more magmatic part or feeder underneath the crater has been modeled geophysically to be 2.5 ha in size. The mineral chemistry of the garnets reflect a typically lherzolitic trend very close to the lherzolite Cr203/CaO line.

It should also be noted that one of the micro-diamond recovered from K4 is a 0.425mm stone. Similar micro-diamond analyses performed in 1999 on this kimberlite recovered a 0.85mm macro-diamond.

The recently released geological interpretation of the Southern African Magnetotelluric Experiment (SAMTEX) project data produced the first pseudo 3-dimensional electrical resistivity map of the crustal and mantle lithosphere beneath the Damara-Ghanzi-Chobe belt and its surrounding Kalahari and Congo tectonic blocks. The Congo and Kalahari Cratons are characterised by very thick and resistive lithosphere, approximately 220km and 240km respectively, which from a diamond perspective is encouraging. The results of this program has, among others, shown that the Company's northern licences are underlain by the Angolan Craton (Khoza et al in press, Muller and Jones 2007) and this means that kimberlites occurring in the most northern licences would be the most interesting from a diamond perspective.

The micro-diamond results and the tectonic reconstruction studies continue to enhance the potential of the Ngamiland diamond project. The diamond exploration program for 2011 will focus on kimberlites K17, K18, and K19 which are the most northerly bodies so far discovered in the Nxau Nxau cluster but for which the Company has very little information. In addition, some kimberlite targets that have been identified further to the north will be scheduled for drilling once the Company's second drill rig arrives on site. Finally, the K10 micro-diamond results are sufficiently encouraging to warrant the sampling of kimberlite K11, which is proximate to K10 and has a similar 2.5ha feeder, for micro-diamond content.
