I've used per tonne prices of $ 18 for ilmenite, $ 100
for rutile, $ 133 for zircon, a 50 % haircut for probable reserves, and 75 % for measured & indicated resources.
I'll be kind & use the same in - the - ground prices as last year (approx. 10 % of medium / long term average spot prices): A price of $ 18 per tonne for ilmenite looks spot on, the $ 100 price
for rutile's mostly irrelevant, and a $ 133 price for zircon's generous considering recent grading & pricing.

This material, in which carbon substitutes
for some of the lattice oxygen atoms, absorbs light at wavelengths below 535 nanometers and has a lower band - gap energy than
rutile (2.32 versus 3.00 electron volts).

I must say however, your «medium term prices» are unrealistically low and I can not support your reluctance to use current spot prices
for ilmenite,
rutile and zircon.
