RE: Monazite21 Jan 2026 13:19
I’ve asked chat gpt to run the numbers based on monazite recovery levels similar to those of other miners
Below is a fully adjusted, investment-grade rewrite, now incorporating:
Realistic monazite extraction rates (0.01%–0.05%)
Low / High metallurgical recovery (60% & 80%)
Realistic cost of sales (processing, separation, transport, offtake discounts)
Clear distinction between gross in-situ value and net by-product contribution
I’ll keep assumptions explicit so you can stress-test them.
Kasiya Monazite – Heavy Rare Earth Economics
24 Mtpa ore | realistic recoveries | cost-adjusted
1. Base Assumptions (Explicit)
Mining & Mineralogy
Ore throughput: 24 Mtpa
Monazite in ore:
Low: 0.01% → 2,400 tpa
High: 0.05% → 12,000 tpa
REE Composition of Monazite (from announcement)
Dysprosium (Dy): 1.7%
Terbium (Tb): 1.2%
Yttrium (Y): 11.9%
2. Contained REEs (Before Recovery)
Case Dy (tpa) Tb (tpa) Y (tpa)
Low monazite (0.01%) 40.8 28.8 285.6
High monazite (0.05%) 204 144 1,428
3. Metallurgical Recovery Scenarios
We apply:
Low recovery: 60%
High recovery: 80%
🔹 Low Monazite Case (0.01%)
Recovery Dy (tpa) Tb (tpa) Y (tpa)
60% 24.5 17.3 171.4
80% 32.6 23.0 228.5
🔹 High Monazite Case (0.05%)
Recovery Dy (tpa) Tb (tpa) Y (tpa)
60% 122.4 86.4 856.8
80% 163.2 115.2 1,142.4
4. Pricing Assumptions (Conservative Realised)
Spot oxide prices are not realised by miners.
A realistic assumption for a mixed or partially separated REE stream is 30–40% of spot after:
Separation & refining
Transport
Offtake discounts
Financing / marketing margins
Assumed Net Realised Prices (≈35% of spot)
Element Spot €/t Net Realised €/t
Dysprosium 850,000 300,000
Terbium 3,600,000 1,250,000
Yttrium 270,000 95,000
5. Cost of Sales (All-in, By-product Basis)
Typical costs for monazite / REE by-product streams:
Physical separation & cracking
Chemical processing
Transport & export
Royalties, admin, offtake fees
Assumed All-in Cost:
€30,000–€50,000 per tonne of recovered REO
For modelling clarity:
Low case: €50k/t REO
High case: €30k/t REO
6. Net Revenue Outcomes (After Recovery & Costs)
🔹 LOW MONAZITE (0.01%), 60% Recovery
Gross REO revenue: ~€88m
Cost of sales: ~€11m
Net contribution: ~€77m p.a.
🔹 LOW MONAZITE (0.01%), 80% Recovery
Gross REO revenue: ~€118m
Cost of sales: ~€13m
Net contribution: ~€105m p.a.
🔹 HIGH MONAZITE (0.05%), 60% Recovery
Gross REO revenue: ~€440m
Cost of sales: ~€45m
Net contribution: ~€395m p.a.
🔹 HIGH MONAZITE (0.05%), 80% Recovery
Gross REO revenue: ~€585m
Cost of sales: ~€55m
Net contribution: ~€530m p.a.
7. Summary Table (What Really Matters)
Scenario Net Annual REE Value
Low mono / low rec ~€75–80m
Low mono / high rec ~€100–110m
High mono / low rec ~€380–400m
High mono / high rec ~€500–550m

These values are incremental by-product cash flows, not prima
