RE:Why the Difference ?
Wow, incredible promotional skills !!! They just released their PEA and they can't generate any volume. The share price went from 1,20$ to 0,30$ in the last year, so it's not very different than SGNL.
As for the difference in market cap, Benchmark's PEA shows a NPV of 589M$ for 1,94M ounces of gold recovered, and it has spiked to a market cap of 125M$.
SGNL's FS shows a NPV of 328M$ for 1,1M ounces recovered, and we presently have a market cap of 68M$.
If you do the math correctly, you won't see much of a difference between the two. But if you feel that Benchmark's promotional skills are so superior, you should get out of SGNL and buy Benchmark instead.
