RE:RE:RE:RE:Sigma DepositWWH,
As I recall, the projection for the top 400m of Sigma RE was coming from a timeline chart (one of the Corp Presentations). At the time, it would seem that this would be the ready-made source for feeding the mill and de Jong was talking about some 200,000 - 300,000 oz. There were postings on the topic but I am no good in digging them out. However, things seemed to fade away, and the company was not too anxious to include this RE as part of their "next RE". The latest thing on Sigma is the whole tree rather than those low-hanging fruit.
If it's only the reworking of the old (historic) data collected by the previous company without doing any additional drilling or going down to the high-and-dry workings (deeper than 400m, assuming that they have been pumping the water out) then it should not take that long to do the analysis. The data are available in digital format (digitized for the GRC last year, they spent ~ $1M to get this done?).
A small team of geos and computer analysts with good analytical skills (they have all the latest softwares for interpreting and manipulating the data) should be able to crank out an updated RE in a few months. I would say 3 months?, or 6 months max.
Again, the time-consuming portion portion would be the checking out of the information involving drilling or underground work (e.g.for the top 400m, or deeper) where people actually have to walk/crawl around to verify drill locations, the gold bearing shear veins (length and width), etc...Having this physical proof of the size of the veins would provide strong support to the new estimate (pictures of those veins would be good). But when it comes to analytical work (with reliable data) then with computer technology, it's just a push of a button. Of course, you need good people with good heads to drive that mouse.
