Good morning Niocorp faithful:

Using today's release I have decided to update the probable extra profit from our mine. https://www.niocorp.com/niocorp-announces-drill-core-assays/

I will repeat my statement. It is my intention to calculate a profit that is achivable, not just wishful.

From today's assays results, we learned that the concentration of rare earth minerals is pretty well spread all over the property. A pretty significant discovery, since we will be extracting them from the residue of the mining of our main 3 elements.

In my previous "white paper", I made some significant guesses. I will keep the guess of the cost to extract the 3 rare earth oxides from the solutions obtained during mining of the main resources at 25%. After further research, the down time necessary for preventive maintenance is less than I expected. I will modify the down time from 60 days to 30 days per year.

Since the assays in today's release are from totally different drill cores as the ones utilized on the ones reported in the Feasibility Study from SEDAR dated 8/10/2017, I will combine them and use the average of the 2.

Terbium Oxide: PPM average: _ _ _ _ 15.63
Dysprosium Oxide PPM average: _ _ _ _ 68.03
Nd Pr Oxide PPM average: _ _ _ _ _ _ 802.0

Since the daily price of the rare earth oxides is extremely dynamic, today's prices will be used: https://www.metal.com/rare-earth-oxides

Price per KG will be used:
Terbium Oxide _ _ _ $1751
dysprosium Oxide _ _ $458
NdPr Oxide _ _ _ _ _ $133

Terbium (Tb):
2,900,000 Kg per day x (extraction rate) .93 = 2,697,000 Kg x (PPM) .0000156 = 42 Kg per day. 42Kg x $1,751.00 (price per Kg) = $73,500 per day x .75 (profit) = $55,125 profit per day X 330 days = $18,191,000 per year profit.

Dysprosium (Dy):
2,900,000 Kg x .93 = 2,697,000 Kg x .000068 (PPM) = 183 Kg per day. 183Kg x $458.00 (price per Kg) = $83,814 per day x .75 = $62,860 profit per day x 330 days = $20,743,000 per year profit.

Neodymium/Praseodymium (NdPr):
2,900,000Kg per day x .93 = 2,697,000Kg x .0008 = 2,157Kg per day x $133.00 price per Kg = $286,881 profit per day x .75 = $215,160.00 profit per day x 330 days = $71,000,000.00 per year profit.

A pretty sweet addition to our bottom line.
Tb - - - - - - - - - - - - - - - - -$18,191,000
Dy - - - - - - - - - - - - - - - - -$20,743,000
NdPr - - - - - - - - - - - - - - - -$71,000,000.00
Profit from the 3 oxides: - - - - - $109,934,000.00

Amazingly enough the clear profit per year is almost identical.

The assays for this last study originated from drill cores located all over the property, over 2000 acres. The assays used in my original white paper, since they were included in the FS, were obtained from the 60 acres only.

I beleive the reason for the last study is to establish that commercially profitable rare earth production could occur on the entire property, not only on the 60 acres included in the FS.

Just my opinion, I beleive our Company should update the FS to include the profit from the 3 rare earth oxides. It is a very considerable amount of profit not currently included.

Have a great day.
