RE: RE: Lowest CAPEX is the big cost to look at, there's not many juniors in the entire world that can beat AAA in CAPEX for a 1 million ton mine. Only South Boulder and Ethiopian Potash that has Colluli deposits can beat Allana due to open pit mining potential but no one else.
According to Dundee's calculation, Allana OPEX is $100 per ton but that cost includes transportation, port cost, etc - the $100 per ton is TOTAL OPEX COST. I've seen others who hypothetically could have lower OPEX but it's not clear if that OPEX would include all costs like Dundee's calculation for Allana did. In any case, Allana beats all on the CAPEX side (except the open pit guys) which is the big cost. All other juniors for a 1 million ton mine have costs exceeding $1 billion, while Allana is ~$800 million. So go ahead and say you see cheaper OPEX costs but make sure you state their CAPEX costs as well, the really big cost. Also, when the rail construction is complete (should be close to the time Allana mine is done), transportation costs are going to come down which lowers OPEX total costs.
Allana still the best junior I see, although Ethiopian Potash could give it a run for it's money when they start reporting on their Colluli deposit. In either case, Allana most likely to have a mine while Ethiopian Potash will most likely be taken out long before a mine so your long term value is still in Allana. South Boulder is in Eritrea and the government will own a % of the mine, so I wouldn't invest in South Boulder (plus it's ASX listed).
Also, when looking at other locations in the world, make sure you account for higher freight costs if they are going to ship to Asia. Ethiopia has a very short shipping distance to India and other Asian countries. Those all go into the price the Asians pay for the Potash so that's a big factor as well.
