Extract Resources, the ASX & TSX listed Namibian uranium miner (ASX:EXT, TSX:EXT) part owned by Kalahari Minerals (LON:KAH) , released the latest drilling results on its Rossing South project on 21st May. Rossing South is the most significant global uranium discovery in decades and is likely to be amongst the world’s top 3 uranium mines once fully in production. For further analysis on Extract, see this: http://www.stockopedia.com/content/the-extract-complex/30317.

Extract currently has the largest mineral drilling programme in Africa underway, with 19 rigs deployed. Since Extract's last JORC resource statement in July last year, the focus has mainly been on infill drilling on the existing known zones 1 and 2. This is necessary to form the basis of Extract's DFS (definitive feasibility study) which is due in the fourth quarter of 2010. I have analysed the latest results and believe that they reveal some interesting new information.

 

New Drilling and Current Resources

Figure 1 - New drilling locations

Figure 1 covers an area of 4.1km East-West x 9.4km North South (it appears stretched east-west due to the underlying spreadsheet used to create the diagram). Each cell represents  a 100m x 100m area. Where an annotation appears in a cell, drilling results have been reported for that cell (either in this month's release or previously). Cells coloured yellow represent infill drilling reported this time in previously drilled cells. Cells coloured green are "virgin territory", previously undrilled (i.e. new exploration). We can see that a significant amount of new explo has been reported this month. I have marked the approximate extent of the previously reported zone 1 and 2 resources on the diagram.

Note that the official JORC resources are 145Mlb U3O8e for Zone 1 and 122Mlb for Zone 2. An independent estimate [1] of additions to those resources by drilling results released since last July suggests that the next official JORC declaration should include at least 173Mlb for Zone 1 and 164Mlb for Zone 2 - representing an aggregate increase of 70Mlb... but that's before new exploration is taken into account.
