A 'going concern' isn't quite the way I'd put it. More of a growing concern. A going concern is a profitable and/or a trading business that sells goods for profits and FLPC is neither because all they do is exist. Quite recently, even Bob said they were on the verge of Filing for insolvency, but they only decided not to and continue to fund it themselves since they bought out Stockpile Resources to give FLPC full control over Fencemaker. Perhaps they have designs on it, but they need to fill in the Shareholder's with progress notices just like they didn't when they bought out Stockpile! Very few knew about that.
FLPC will not have the cash to convert FM to profit, so they need to find someone brave enough to pour money into it and hope for the best. Don't forget it was last mined in the 1970s and heavily Mined around 30 years prior. If it were really worth it, they would have been digging it out not that many years ago!
They should have a 'For Rent' notice put out in the Mining Mag's. If they were so sure about it, why not advertise the fact that it is 'full of Antimony Ore'? Adverts are cheap enough, but if they won't even do that, it just goes some way of proving that FM could be less of a 'Gold' Mine than it's all cracked up to be.
