Any mine regardless of the economic vitality presented by a PEA, has many unpredictable risks along the road to profitability. These risks are lowered by a strong management team but increase when taking on debt to commence the mining operations. Even if Carnac was to get really good financing terms, It is not too likely they could have realized an 8M in profit within a two year timeframe of operations.
Bottomline is;
If CRCUF could pull off buying and selling mines at five times their investment about once per year, they could turn a much larger profit in less time and with less risk.
