The following is an account of the recent results from systematic grid bulk sampling work, part of a continuing program, now being executed in the Lower Chicoria Creek - Upper Sorrisso River Area of DIAGEM Property 213, Juina Diamond Province, Mato Grosso State, Brazil. The diamondiferous gravels that are being sampled are lying on the slopes in terraces and buried channels and in the flats and beds of the two water courses.
The speed of bulk sampling has been increased dramatically during the last six weeks, due to adopting new sampling arrays and methodologies. The present second set of five bulk samples have been completed in the last 14 days bringing the total completed in the last four weeks to ten. This second set of bulk sample results has returned grades as high as 0.58 carats per cu.m., with an average grade of 0.42 carats per cu.m. These results confirm the encouraging results from the first set of samples reported May 29, 2003, and demonstrate consistency over an area approaching one kilometre in length.
So far, the grid samples have spread over an area of approximately 700X300 metres or 210,000 sq.m., remaining open in both directions. The overall grade, for this area, is averaging 0.40 carats per cu.m., with a very respectable average diamond size of just under 0.40 carats - the best results, to date, from this particular river system. Gravel thickness has averaged 0.68 of a metre and average overburden is a modest 1.75 metres, giving a stripping ratio of 2.6:1 and inexpensive recovery procedures.

The recent successful introduction and application of fast bulk sampling methods have included, while doing the first step gravel delineation work, an ilmenite intensity and grain size survey whose results, when contoured, indicate the gravel areas most likely to contain higher diamond grade.
The Company also reports that its first 'Sortex'x-ray diamond selection and sorting facility, has been constructed and is now undergoing testing. The Sortex machine uses x-rays to select diamonds from other heavy minerals collected in the concentrate. Implementation of this 'hand-offs'mechanized process will significantly increase control over diamond security and improve the efficiency of diamond recovery.
