In short: The call "was essentially about Renergen," with COO Nick Mitchell alongside Mann. They are commissioning the plant and ramping production, expecting completion and first shipments early next month, and are contracting out production — 3/4 of Stage 1 by the end of next month, half of Stage 2 by the end of the year. "Pricing is very strong": the first helium deal was done at $600/mcf and they are "now seeing prices higher than that, potentially up to $1,000," all take-or-pay 5- to 15-year contracts; LNG is selling between $15 and $20. Renergen's Stage 1 nameplate production and Stage 2 contracting are also two of the three conditions on the $500m DFC / $250m Standard Bank funding.
Renergen is the operating business behind ASP Isotopes' helium story: a gas project at Virginia in South Africa's Free State that produces helium along with methane, which is chilled into LNG (liquefied natural gas) and sold to industrial and transport customers. It now sits inside ASP Isotopes rather than standing alone — its COO, Nick Mitchell, was on this call beside the ASPI CEO — so this entry is about the asset, and the way to own it is the parent.
Where it stands: the plant is in commissioning, which is the shakedown phase between "built" and "running properly," and management expects that finished with first shipments early next month. In parallel they are signing customers — targeting three-quarters of Stage 1 output contracted by the end of next month and half of Stage 2 by the end of the year. That order matters: the lenders behind the $750m package want to see contracted volume before they release money, so the sales book is deliberately being built ahead of the build-out.
The economics reported here are strong. Helium's first contract was done at $600 per mcf, with management saying it is now seeing "potentially up to $1,000" — and crucially on take-or-pay terms running five to fifteen years, so the buyer is committed to pay for the volume regardless of whether they take it. Helium has no exchange-traded spot price; every deal is negotiated privately, which is why hearing a realised contract number straight from a producer is genuinely informative. The LNG by-product sells for a comparatively ordinary $15 to $20.
In short: The focus of the presentation. "We actually started that plant up this week" with first product to customers "during September" and nameplate by the end of Q4 as the final wells are tied in through October. Phase 1: ~70 mcf/d helium + 2,500 GJ/d LNG → ~$27m revenue and ~$11m gross profit at $600/mcf and $13–14/GJ; at the $800–1,000 he says customers are now discussing, "$15 to $20 million in gross profit from just phase one" — spot is "north of $2,000 I'm told by industry participants." Phase 2 is 13× the size — 900 mcf/d + 34,000 GJ/d, "more like $370 million in revenue and $300 million in gross profit" — funded with $500m from the US DFC and ~$250m from Standard Bank, built turnkey by an EPC over 44 months, first production 2030 and first full year 2031. The gas runs 3% helium vs 0.4% in US gas and 0.04% in Qatar; 1P reserves are "about the same size as what the US federal helium reserve is."
Helium cannot be manufactured. It is produced underground by the slow radioactive decay of uranium and thorium, gets trapped in rock alongside natural gas, and escapes Earth's atmosphere permanently once released — so the only way to get it is to find gas that happens to contain it and separate it out. Almost all natural gas contains a trace: about 0.4% in a typical US well, about 0.04% in Qatar. Renergen's gas at Virginia in South Africa's Free State runs about 3%, which is roughly seven times a US stream and seventy-five times a Qatari one. That grade is the entire investment case: it means a physically small field can be commercially significant, because you are not paying to process a hundred times as much gas to get the same helium.
The timing is what makes this appearance interesting. Mann says the Phase 1 plant "started up this week," first customer shipments go out in September, and it should reach full designed output by the end of the fourth quarter once the last wells are connected in October. Phase 1 produces about 70 mcf a day of helium (an "mcf" is a thousand cubic feet) plus 2,500 gigajoules a day of LNG. At $600 per mcf, that is roughly $27m of revenue and $11m of gross profit a year.
Then comes the leverage. Because the plant's output volume is fixed and most of its costs are fixed, almost every extra dollar of price falls straight to profit. Mann says he is currently negotiating at $800–1,000 per mcf, at which the same Phase 1 plant produces $15–20m of gross profit; he has been told spot prices are above $2,000. Treat those three numbers as three different confidence levels — $600 is contracted, $800–1,000 is being negotiated, and $2,000 is second-hand.
Phase 2 is thirteen times bigger: 900 mcf a day of helium and 34,000 gigajoules of LNG, which at the same $600 would be about $370m of revenue and $300m of gross profit. It is funded largely with debt — $500m from the US government's development-finance arm and about $250m from Standard Bank — and built under a fixed-scope turnkey contract by an outside engineering firm over 44 months, meaning first production in 2030 and a first full year in 2031. So this is one asset with a near-term cash flow and a long-dated, largely debt-financed expansion behind it.
Two smaller details are worth carrying. Sales are on five- to fifteen-year contracts indexed to South African producer-price inflation, with 100% of the LNG and 50–75% of the helium already committed and the rest sold at spot — long contracts make the project financeable, while the uncommitted slice keeps upside if the shortage worsens. And about 1% of a liquid-helium cargo boils off every day it is at sea, so shipping distance is literally a cost of goods; the Cape of Good Hope sits within reasonable reach of every major market, which means customers receive more liquid and less gas than they would from a more remote source.
14:39So this talks about the size and the scale. So phase one, we expect to produce about 70 MCF a day of helium, about 2,500 gigajoules a day of LNG. And for those in the United States, a gigajoule is approximately equal to an MMBTU. And if we can achieve a sales price of say $600 per MCF on average and say 13 to 14 per gigajoule for the LNG, phase one should generate revenues of somewhere close to $27 million and gross profit of about $11 million.
