AJM have a Mkt Cap. 3 times that off AGO, they won't be making an cash until later this year, whereas AGO is already maling making good money on their Iron Ore, and lithium later this year.
Altura Mining
Mkt Cap. of $861 Million
Shares issue 1.81 Billion Atlas Iron
Mkt Cap of $287 Million
Shares issue 9.28 Billion
But AJM also have a bigger debt($128M) and at a higher interest rate (14 to 15%).
AGO has a debt of $103M at an interest rate of around 9% (Not sure of this, it is supposed to be 4.3% higher than US Libor, plus other interest factors)
They currently have $111M in cash, whereas AGO last reported to have $114M in cash.
In any case, this is just another example that AGO is undervalued. They are in a better financial situation than AJM, and yet their Mkt Cap. is 1/3 of AJM.
