Solid post gumboot and thanks for sharing.
As we await the DFS (or amendment / addendum etc) for the final monazite grade to run the implied monazite content, but we can already piece together a very compelling picture. What we know so far is world-class: NdPr at 21.8%, DyTb at 2.9%, and Yttrium at 11.9%. With other rare earths like Cerium and Lanthanum likely making up another 25% to 30%, the Total Rare Earth Oxide (TREO) typically accounts for about 62.5% of the total mass.
To reverse engineer the potential, we look at the grades. With Rutile at 0.96% and Graphite at 0.95%, we can imply a monazite ratio of roughly 1:40. This suggests a monazite grade of 0.024%. If Heavy Minerals (HM) make up ~6% of the ore, that equates to 0.40% Monazite in HM. For comparison, Fortuna—just 20km away—measures 0.32%, while we benefit from a higher magnetic delta of 2.9 amps versus their 2.4 amps.
Based on a 12,000,000 tpa ore throughput, a 2.51% combined grade, and an 85% recovery (which might be a touch aggressive, but possible), we get roughly 1,024 tonnes of concentrate per year. Because of the high quality, this sand would likely fetch $10,500 per tonne rather than the standard $8,500, generating $10.7 million per year just from selling the raw concentrate.
While my understanding is that SVML isn't currently looking at the later stages, the full picture is staggering. Moving to Stage 2 (chemical acid leaching) moves the price to $45,000/t ($46m/yr). Moving to Stage 3 (refined oxides via solvent extraction) hits $125,000/t, or $128m/yr. These revenue figures effectively double after the year 5 ramp-up, potentially reaching $260 million a year if SVML and Rio decide to become a refining powerhouse.
The Capex to reach Stage 3 would be around $520 million, offering a lightning-fast 2-year payback. This is a high-margin "add-on" with an incremental IRR of 45% to 50%—which is unheard of. When you blend that with the base 23% IRR, the total project IRR jumps to ~36%. That brings the total capital cost to $1.75 billion against an annual profit of $736 million.
Of course, these are the usual caveats as I'm piecing together what could be, rather than what is currently fact. We await the final details to re-run the numbers. For now, the focus is on getting the ESIA ready and submitted, easier said than done, I know! Good luck to the team. If a Rio decision lands around 14 July (hopefully!), they may see this as a Tier 2 prospect on their radar, but the positives at SVML are simply becoming too big to ignore. GLA
