During the 2002 field season, a total of 130 regional samples were collected by APEX Geoscience Ltd. and processed at the Saskatchewan Research Council. Of these samples, 27 yielded diamond indicator minerals with one sample containing 45 pyrope garnets and two eclogitic garnets grains. Probe confirmed kimberlitic grains include pyrope garnet, olivine, chrome diopside, chromite and ruby corundum. These new results confirm those previously obtained, whereby 46 per cent of the 107 total pyrope garnets identified in 29 samples were G10 subcalcic pyropes as defined by Gurney (1984). Three of these G10 pyrope garnets are significantly subcalcic and have the following compositions: (1) 12.27 per cent Cr2O3, 2.83 per cent CaO; (2) 13.96 per cent Cr2O3, 4.75 per cent CaO; and (3)12.45 per cent Cr2O3, 3.72 per cent CaO.
