### Hello gents,

I forget what all we were including in these data dumps. A lso, I have (3) 2010 Queenstake roaster tests not in the dbase that have not been reviewed. If you like I can send the stack test report summary pages. We had spoke earlier about sending PDFs, but to be frank, that's going to be a bit of work to cull tho se out of the files

-- so unless you are sure that you need those I'll stand by and wait for your word until I ship those.
