Hey there,
the grab sample that you have mentioned has been apart of the corporate presentation for awhile now - in most recent as of dec 4 - slide 13 - grab sample in the middle is the one just over 6000gpt
the news release from oct 1 2007 - has a picture of the same grab sample with visible gold on page 4 in right colum but no mention of the grading
Hope this helps a bit - still have to do some more reading through archived nr's to see when results were released
