While I type this, SLR is trading at 3.27, IGR should be trading at 52c. ($3.27 / 6.28 = .52c). But IGR usually lags by a cent or so as there is more risk associated with IGR. That is, the merger doesn't go through to completion.
Both SLR and IGR opened strongly, so as long as gold keeps up around US$1700, then 51c must surely get beaten soon.
A close above 51c will be a very positive sign!
