Ann: HIGH POTENTIAL STRATEGIC ACQUISITION EQUADOR NIOBIUM PROJECT, page-199

Given that SUM has Tantalum worth 4 times the price of Niobium and twice the Weight,
Means it is actually worth about 8 times the Price of Niobium in ppm or percentage.

SUM is from surface,
In a Country that has cheaper Drilling and Labour costs.

It only needs a far smaller deposit size for the same value.

Even 0.125% Tantalum grade is worth the same as 1% Niobium grades !!!!

That's not even including the Niobium value which would put it at 9 times the value of Niobium alone,
At the same percentages of each.

It can be over ten times the value
or more if Tantalum grades are higher than Niobium.

So actually SUM could have a deposit a tenth of the Size,
and have the same or higher value of material in the ground.

Then it has the advantage of being near:
Roads,
Water,
Power,
Workers and Accommodation.

So SUM has even more advantage.
Not having the expense of building a Town in the Middle of nowhere.
As well not having to build all the other things like Roads, Accommodation, Water Treatment Facilities,
A Power Station and much much more....

Not to mention SUM does not require expensive FIFO workers,
As it is near to workers who can get there via road etc.

Being from surface not 50 metres underground also makes SUM better value,
Not needing to spend Millions if not Billions digging before hitting the deposit.

So in reality SUM probably only needs a deposit a 20th of the Size,
To make the same amount of $$$$

Actually that makes SUM seem even more Undervalued !!!!
