Aminex: From Acorn to Oak – Chapter 9: Seismic & Scale-Up

The data that turned a discovery into a giant

---

With the farm-out complete and funding secured, the stage was set for the next big step: a fresh look beneath the surface. Until then, Aminex and its partners had relied mostly on 2D seismic data and the encouraging results of Ntorya-1 and Ntorya-2. It was enough to prove hydrocarbons, but not enough to map the full extent of the resource.

That changed when 3D seismic was acquired across the Ruvuma acreage. For the first time, the subsurface could be seen in high resolution. The results were striking. Structures that had been hinted at on 2D were revealed in detail. Reservoir connectivity was better understood. New drilling targets came into focus.

Most importantly, the numbers jumped. Independent assessments, incorporating the new seismic data, lifted the estimated gas in place from the hundreds of billions of cubic feet into multiple trillions. Ntorya was no longer just a promising field — it was Tanzania’s largest onshore gas development in the making.

For Aminex, still holding its 25% interest on a free carry, the upgrade was a game-changer. The farm-out had already ensured the company would not be bankrupted by development costs. Now the seismic confirmed that the upside was far greater than originally imagined. A quarter share of a small discovery is one thing; a quarter share of a multi-TCF basin is quite another.

The new seismic also laid the technical groundwork for the Chikumbi-1 (CH-1) well. Designed to test deeper zones and provide further calibration of the seismic data, CH-1 would help convert gas in place into booked reserves — the critical step for financing and long-term planning.

For shareholders, the 3D seismic was the moment the story shifted gears again. Ntorya wasn’t just commercial — it was strategic, both for Tanzania’s energy security and for Aminex’s future.

➡️ Next time: Chapter Ten — To Be Continued. With the CPF under construction, pipeline contracts in place, and CH-1 on the horizon, the next RNS will carry the story into first gas and the long-awaited cashflow era.

Aminex: From Acorn to Oak – Chapter 7: The Ruvuma Basin Story

Ntorya’s promise and the wells that proved it

---

If Kiliwani North was Aminex’s proof of concept, the Ruvuma basin was always the real prize. Stretching across southern Tanzania and into Mozambique, this frontier play had the scale to change the company’s future — if it could be unlocked.

The first breakthrough came in 2012 with the drilling of Ntorya-1 (NT-1). The well flowed at around 20 MMcfd of gas, with light condensate. For the first time, Aminex had a discovery of material size — one that could support development rather than just prove hydrocarbons existed.

Five years later, in 2017, the partners drilled Ntorya-2 (NT-2). This wasn’t just a repeat exercise — it was confirmation. NT-2 flowed at rates above 17 MMcfd and extended the known limits of the reservoir, it even brought the excitement of oil shows in the mud cuttings! With two wells delivering strong results, independent assessments began to point to hundreds of billions of cubic feet, and potentially over a trillion cubic feet, of gas in place.

For Aminex, NT-1 and NT-2 were transformational. Together they showed that Ruvuma wasn’t a marginal basin — it was one of East Africa’s most exciting undeveloped gas assets. But success brought a new problem.

Big discoveries demand big money. Building a processing plant, drilling more wells, and laying a pipeline to Madimba would cost hundreds of millions of dollars. For a junior like Aminex, already stretched by years of exploration, that scale of capex was impossible to fund alone.

It left the company at a crossroads: hold onto the prize and risk running out of money, or bring in a heavyweight partner with the resources to carry it forward..

The Ntorya discoveries proved the potential. The next challenge was to secure the funding and expertise to turn them into production.

➡️ Next time: Chapter Eight — Farm-out & Transformation. We’ll follow how Aminex brought in ARA Petroleum, secured a $35m+ free carry, and positioned itself for a share of future cashflow without the burden of development costs.

Aminex: The Ruvuma Basin Potential That Could Transform Ntorya

Beyond current reserves — how 16+ Tcf of gas, condensate uplift, and possible oil could multiply Aminex’s value many times over.

---

1. From Current to Future

So far, our valuation discussions have been based only on 0.4 Tcf net to Aminex, which is the currently recoverable gas booked at Ntorya. That alone already suggests strong upside to today’s share price.

But the real long-term prize is the Ruvuma Basin itself, where independent assessments point to 16+ Tcf unrisked potential.

If the mapped ~16+ Tcf unrisked potential were progressively proved up during Full Field Development, Aminex’s 25% stake could reach up to 4 Tcf net — ten times larger than today’s discovered share! Even partial success (say 25–50% of that potential) would still lift Aminex’s net exposure to roughly 1–2 Tcf, materially above today’s booked ~0.2–0.4 Tcf.

---

2. The Numbers — Scaling Up

Let’s use the same pricing assumptions as before:

• Base Case: $4.00/Mcf (domestic tariff)

• High Case: $6.10/Mcf (industrial tariff)

For 4 Tcf net to Aminex:

• Base Case → ~$16 billion gross sales

• High Case → ~$24.4 billion gross sales

Even after PSA splits (conservatively assuming 55–60% government take, though Aminex has agreed favourable terms), that still implies:

• $6.8–10.4 billion net to contractors

• $1.7–2.6 billion net to Aminex

Divide by 4.22 billion shares:

• Base Case ~31p/share

• High Case ~47p/share

That’s an order of magnitude higher than today’s 1.95p.

---

3. Condensate Uplift & Oil Potential

The basin story is not only about gas:

• Condensate uplift: Ntorya gas is expected to carry ~15% additional liquids value, providing a premium revenue stream on top of gas sales.

• Oil upside: Drilling at NT-2 encountered oil shows in the mud, suggesting a deeper Jurassic oil play exists. If confirmed in later phases, this could open a whole new layer of value.

---

4. Why Investors Care

Cove Energy’s billion-pound sale in 2012 showed that when majors see multi-Tcf scale, they pay heavily for it. Ntorya is onshore, with lower costs and direct access to Tanzania’s growing market — factors that make it even more attractive strategically.

Long-term holders believe much of the 16+ Tcf potential will be proved up, turning Ntorya from a domestic gas play into a basin-scale energy hub with regional importance.

---

5. The Investor Takeaway

• Current reserves justify near-term upside.

• Basin potential could multiply Aminex’s value 10× or more.

• Condensate uplift (+15%) and possible oil add further optionality.

• Tanzania’s strong government backing and infrastructure funding reduce project risk.

---

📌 Closing Line:
“The discovered reserves at Ntorya are already valuable — but the 16+ Tcf potential of the Ruvuma Basin is what could truly transform Aminex. With condensate and oil as additional prizes, the long-term upside is not just incremental, but potentially transformational.”

Aminex: What Ntorya’s Gas Could Mean for the Share Price

From current reserves to full-field potential, a closer look at revenues, PSA terms, and cost recovery.

---

1. Headline Upside — The Big Picture

Aminex’s share of currently recoverable Ntorya gas is estimated at ~0.4 Tcf.

Using a base case domestic tariff of $4.00/Mcf and a higher industrial price of $6.10/Mcf, the gross lifetime sales values come to:

• Base Case $4.00 → $1.6 billion

• High Case $6.10 → $2.44 billion

With 4.22 billion shares in issue, that equates to headline values of:

• 28.8p per share (base)

• 43.9p per share (high)

👉 These are gross, pre-PSA figures, but they show why investors get excited: even the currently booked reserves generate multi-billion-dollar numbers.

And this is before considering condensate uplift, oil upside, or basin-wide volumes.

---

2. PSA-Adjusted Reality — Still Attractive

Tanzanian PSAs normally allocate around 55–60% of profit gas to government/TPDC. However, Aminex has publicly highlighted that favourable conditions have been agreed in the amended PSA (commercially sensitive and not disclosed in detail).

That means the actual government take could be less onerous than the typical model — but even on conservative assumptions:

• Base Case ~3.0p/share

• High Case ~4.7p/share

versus the current 1.95p share price.

That’s 50–140% upside — based only on what is currently recoverable.

---

3. How Cost Recovery Works (Capex & Opex)

A common misconception is that capex and opex simply reduce Aminex’s share. Under Tanzania’s PSA, that isn’t true.

• Operators can recover up to 50% of gross annual revenues as “Cost Gas”.

• This applies to both capex and opex until all are fully repaid.

• Unrecovered balances roll forward each year until cleared.

Example:

Suppose capex is $250m, and annual revenues are $200m.

• Year 1: $100m recovered (50% of $200m)

• Year 2: another $100m recovered

• Year 3: $50m recovered → capex fully paid off

From then on, more of the revenue flows directly as profit gas.

Opex is treated the same way — recoverable under the 50% annual ceiling — which means operating costs are also reimbursed before the profit split.

👉 This is why cost recovery actually improves early cash flows to contractors and ensures long-term netbacks are higher than raw PSA splits suggest.

---

4. The True Prize — Full Field Development

Everything so far is based only on ~0.4 Tcf net recoverable to Aminex. But the Ruvuma Basin has an estimated 16+ Tcf unrisked potential.

If proved up during full-field development (FFD):

• Aminex’s 25% stake = ~4 Tcf net

• That’s 10× larger than today’s discovered gas

• On the same multiples, the per-share potential could be 30p–47p turning into 300p–470p

And there’s more:

• Condensate uplift is expected to add ~15% additional value to gas sales.

• Oil shows at NT-2 strongly hint at a deeper Jurassic oil play, which could be targeted in later phases of development.

Long-term holders therefore anticipate not just steady gas monetisation, but a basin-scale growth story with multiple revenue streams.

---

5. Investor Takeaway

• Current Recoverables: Already justify upside against today’s 1.95p share price.

• PSA Economics + Cost Recovery: Show Aminex can recoup capex/opex and still achieve strong netbacks.

• Full Field Potential: 16+ Tcf basin, condensate uplift, and possible oil add layers of transformational upside.

---

📌 Closing Line for Investors:
“Even using conservative PSA terms, Aminex’s share of Ntorya already implies material upside. With cost recovery mechanisms improving early cash flow, condensate and oil adding extra value, and the 16+ Tcf basin potential still to be proved, the long-term case for Aminex remains one of scale and strategic importance.”
