Whilst I've no reason to put much store by SGR's timeline projections, hopefully the following report extracts are factual~

3rd Feb 2010 NR ~ San Gold also reports that development has commenced toward the “007” zone from the Hinge decline. Mobilization of the mining contractor Cementation took place during the first week in January and advance of approximately 20 feet per day is now underway with contract crews. This initial access drift is approximately 550 meters (1800 ft) long and is expected to reach the “007” zone late in the second quarter.

Mar 1st 2010 NR ~ Development towards the 007 Zone is underway, originating from the Hinge decline with over 660 feet (200 meters) completed to date. An additional 1,500 feet (450 meters) remain in order to access the zone at 820 feet (250 meters) vertical depth where initial development and bulk sampling of the 007 zone is anticipated to begin in the third quarter, 2010.

##### 007 tunnel started Jan 2010, 2 months' work to 1-3-10 and 200m done ~ around 100m per month or 3.3m per day. 450m to go from 1st March 2010~ 4.5 months, takes to mid - June.

If it slows by 40% to 2m a day as the tunnel lengthens, that would be 60m a month. 450m / 60m = 7.5 months, would mean mid-Sep.

Nov/Dec would be 9 months, 50m per month, or a 50% slow up.

#####

I'm having trouble pinpointing the start of the Hinge decline for comparison, but

22Oct 2008 NR ~ Over 300 meters (1000 ft) of decline access has been completed to date, with less than 2 months of access development remaining before reaching the first ore levels.

19Feb 2009 NR ~ Over 700 meters (2300 ft) of decline access has been completed to date, with less than week of access development remaining before reaching the first ore levels

##########

Finishing up the hinge decline, 400m in 4 months, 100m per month, seems to have been acheived, consistent with the first 200m of the subsequent 007 extension, at 100m per month.

Replicating these 600m of tunneling would mean June 2010, a 40% slow up woudl mean Sep 2010, a 50% slow up would mean Nov/Dec 2010. Is there a reason for a slow up, which would buck SGR's 600m+ excavation trend?

In my estimation, using SGR's reported facts.
