If all goes well with the pending eis and funding approvals bgd will hit in excess of 60c, i bought into bgd with this in mind. Now im looking at holding medium to long term at least with a percentage of my holding.
have any of you longer term holders looked into what bgd "could" be worth when up and running, based on the planned 5mtpa?
i know a lot of variables at play here eg, local/non local ore and future ore/steel pricing, so a ball park figure would be appreciated.
thanks guys...
ps. any comments on my 60c+ price target, (for or against) welcomed.
