Quick and dirty case study for ore prospecting for Unobtanium on Pandora, author Heppen, all numbers are probably off by alot, don't go chasing after the ore without contacting your town geologist!

unobtanium: kg price 20'000'000 $

assuing you can extract all of the unobtainium in the lirhosphere

Pandora;

Mass: 0.72 earth units

429'984'000'000'000'000'000 kg (4.29e24 kg)

mass of lithosphere 9.3522e+22

Gravity 0.8 g -> higher rock density than earth, ish

Diameter 11447 km (earth 12,742 km)

rock composition;

assuming simmilar conditions as earth

-> not evenly distributed ore in rock mass

ore grade? lets say 0.000001 ppm (1e-10%)

mass * grade = unobtanium mineral

price of infrastruckture: 1'000'000'000'000 $, 10e+12

in whole planet{

(unobtanium in planet: 4.29e+18 kg

market value: 8.58e+25

profit: 8.58e+25)

}

in lithosphere

unobtanium in lithosphere: 6.006e+22 (mass)* 1e-10% (concentration)= 93522000000 kg

value: 1.87044e+18

profit: 1.87034e+18 megaprofit!

if price of infrastructure: 1e17 $

value: 1.87044e+18

prifit: 1.77044e+18 megaprofit!

this shows that the profit would be huge given the current price of infrastructure and mining on Pandora is profitable (even though its galena they show as the mineral...)
