GBP tbh Trombone, of course it's far in the future to realise such market caps and it's important that we all realise that it's still an exploration project that can also go wrong. But for instance if you ask ChatGPT for a valuation of a success case (I know ChatGPT is far from perfect, but probably better than I am at it, while I try to give the reasonable prompts), you get the below. Again, that is a big success scenario for Boland and a big success scenario (albeit not a max Cadia-like success scenario) for Manna Hill, so that is undoubtedly on the very very very high end of what is realistic and would require everything to go right over the next 3-5 years.
Prompt: "what could be the eventual fair market cap if both assets succeed, Boland a 500Mt ore resource with 1000ppm TREO/250ppm MREO, and Blue Rose a solid (but not Cadia-like) skarn & porphyry deposit"
Answer:
1. Boland ISR – 500 Mt @ 1000 ppm TREO, 250 ppm MREO
Tonnage math
500 Mt × 0.10% TREO = 500,000 t TREO
25% MREO bias = 125,000 t MREO, which is the value driver
Basket value (current prices, 2025)
Basket (with 25% NdPr/Dy/Tb, 75% cheap La/Ce) ≈ US$28–32/kg REO (we ran this earlier)
In situ REO value = 500 Mt × 1,000 g/t × (US$30/kg ÷ 1,000) ≈ US$15 billion gross metal value (GMV)
Payability & recoveries
ISR recoveries: say 60–70% (bench + field efficiency)
Payability uplift (if they strip La/Ce): ~80% of basket value (vs industry 70%)
So:
Realisable value = US$15b × 0.65 × 0.8 ≈ US$7.8b
NPV / EV multiple
Cost structure could be bottom quartile if ISR really works → say US$10/kg REO opex vs $30/kg basket = fat margin.
At 7.5–8% discount rate, you might capture ~30–40% of in-ground value in NPV → call it US$2.5–3.0b NPV.
Assign 0.5–0.7× NPV as fair EV at Feasibility/production-ready stage → US$1.3–2.0b (A$2–3b) attributable.
2. Blue Rose + porphyry system
Skarn scenario
Suppose they delineate 20–30 Mt @ 1.5–2% CuEq (Cu + Au credits).
That’s ~300–600k t CuEq metal in a shallow, mineable skarn.
At US$9,000/t Cu, in-ground GMV = US$2.7–5.4b.
Discount heavily for cost/strip/etc → US$0.5–1.0b NPV plausible.
Porphyry upside
If the system yields a Cadia-like monster, the upside is huge, but you said assume not Cadia-like. So let’s be modest:
A 200–400 Mt @ 0.4–0.6% CuEq porphyry is still a company-maker → 0.8–2.4 Mt CuEq metal (~US$7–20b GMV).
Even at conservative valuations, that’s another US$0.5–1.0b NPV.
So combined Manna Hill optionality = US$0.5–2.0b NPV, fair EV maybe US$0.3–1.0b (A$0.5–1.5b).
3. Barton package
A$15m hard asset, negligible in the grand scheme.
4. Sum-of-the-parts “success case”
Boland (ISR HREE): A$2–3b
Manna Hill (skarn + porphyry): A$0.5–1.5b
Barton stake: A$15m
Total eventual fair market cap (success case): A$2.5–4.5b (~£1.25–2.25b)
