Karl,

I finally finished entering drill results for a resource calc for all reported holes. Came in at 67.2 M oz. including the new holes.. not bad considering I know zip about how it's really done, also I found about 20 errors in various categories for the Bre-X figures (caught by the wonders of spreed sheet technology), but the total error is probably +/- 1 M oz, I had to make some judgement calls. The Bre-X dud holes lopped about 1.1 M oz from my totals without the duds. Judging by my past ratio of estimates to Kilborn's, Kilborn should come in at around 73.5 M if they included the latest results. BTW, something no-one has mentioned that I have seen, I found a stealth deep-hole result in the latest Bre-X drill PR. In the PR there are deeper intercepts for a previously reported hole, SEZ-64 BSSE-155 going down to 707 meters with the majority of additional gold in the 416-492 meter range.

Other interesting figures.... for all of Busang about 47 percent of all core contains gold (53 percent does not), between SEZ-44/69 about 60% does (40 percent does not). The top 10 kilometers of core accounts for about 30 million oz.

For the die-hard map fanatics, I made two small corrections to the map, moving dud hole BSSE-246 one unit to the right, and correcting hole BSSE-168 from the 10 > 0 range to the 20 > 10 range. Also, the Bre-X dud holes are now labelled.

Interesting that Freeport changed "insignificant" to "inconclusive".
