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.”

What Is Aminex’s 0.4 Tcf of Gas Really Worth?

Breaking down Ntorya’s discovered resources, gas pricing, and billions in potential sales revenue.

---

Asking the Question

In our first two articles we compared Ntorya’s discovered gas with Cove Energy’s 2012 sale, and then explored the much larger basin upside. But let’s pause on a simpler, practical question:

“If Aminex’s share of Ntorya is ~0.4 Tcf recoverable, what could that actually be worth in revenue?”

---

The Price of Tanzanian Gas

Gas in Tanzania is not sold at global LNG prices but at regulated domestic tariffs. Still, the market is attractive because:

• The Gas Sales Agreement (GSA) for Ntorya is already signed.

• Demand is guaranteed: gas will feed directly into power plants and industrial users via the Madimba plant and national grid.

• Industrial tariffs have been reported around $6.10 per thousand cubic feet (Mcf) — reflecting a blend of state-regulated pricing and the premium paid by industry.

• For sensitivity, we can also consider a lower $4.00/Mcf base case (a conservative benchmark for domestic gas).

(Orca Exploration’s 2023 results showed average realised prices above $6, which reinforces the higher case as realistic.)

---

Step 1: How Much Gas is 0.4 Tcf?

• 1 Tcf = 1,000,000,000,000 cubic feet.

• 0.4 Tcf = 400,000,000,000 cubic feet.

• In units of 1,000 cubic feet (Mcf):

  • 400,000,000,000 ÷ 1,000 = 400,000,000 Mcf.

---

Step 2: Apply the Prices

• Base Case $4.00/Mcf

  • 400,000,000 Mcf × $4.00 = $1.6 billion gross revenue.

• Higher Case $6.10/Mcf

  • 400,000,000 Mcf × $6.10 = $2.44 billion gross revenue.

So even Aminex’s 0.4 Tcf net discovered share alone could generate between $1.6bn and $2.4bn gross sales over the life of production.

---

Step 3: What Does That Mean for Aminex?

Of course, gross sales are not the same as free cash:

• Tanzania’s Production Sharing Agreement (PSA) splits revenue with the government.

• Capex and opex must be recovered.

• Timings matter — revenues arrive over many years, not in one lump sum.

But the exercise shows something important:

• Even using conservative domestic pricing, Aminex’s discovered gas represents a multi-billion-dollar gross revenue stream.

• Against a current market cap of ~£80m (≈$100m), that scale looks highly attractive.

---

Step 4: The Benchmark

To put this in context:

• Orca Exploration reported average realised gas prices of over $6/Mcf last year.

• That aligns neatly with our $6.10/Mcf higher case.

• It reinforces that Ntorya’s gas, once flowing, is likely to achieve pricing toward the higher end of our range.

---

Closing Thought

Asking “what is 0.4 Tcf worth?” shows why Ntorya is such a strategic asset. Even before considering the 16+ Tcf upside in the wider basin or the possibility of oil, Aminex’s discovered gas alone equates to billions of dollars in potential sales.

And with TPDC funding the pipeline and infrastructure in place, this value is not a theoretical number — it is linked directly to a contracted market hungry for supply.

For investors, that underlines the simple truth: Ntorya is underpinned by real demand, real contracts, and real scale — and the upside could be far greater.

Beyond Ntorya: Unlocking the 16 Tcf Potential of the Ruvuma Basin

Why future drilling, deeper horizons, and even potential oil could transform Ntorya from a domestic gas play into a basin-scale energy hub.

---

From Discovered to Potential

In our previous article we compared Aminex’s current discovered share of Ntorya gas with Cove Energy’s position in Mozambique back in 2012. That comparison was based on today’s proven gas only — roughly 0.4 Tcf net to Aminex.

But Ntorya sits within the wider Ruvuma Basin, a structure that independent assessments and operator mapping suggest could hold 16 Tcf or more of unrisked gas potential.

This is where the real long-term opportunity lies.

---

Why Basin Potential Matters

Majors don’t just buy into what has already been booked. The Cove Energy bidding war showed that upside scale is what excites strategic buyers.

• Cove’s 8.5% stake equated to ~5–6 Tcf net when sold.

• If future drilling proves out Ruvuma’s 16+ Tcf potential, Aminex’s 25% stake could represent ~4 Tcf net.

• That’s on par with Cove’s net interest — but onshore, with lower development costs and direct access to a growing domestic market.

---

The Jurassic Oil Angle

Ntorya’s story isn’t just about gas. During NT-2 drilling, oil traces were identified in the mud — evidence that deeper horizons could contain liquid hydrocarbons.

Originally, the Chikumbi-1 (CH-1) well was planned to target multiple stacked levels, including the deeper Jurassic formation. The revised location focuses only on gas, reflecting Tanzania’s immediate priority for domestic supply.

But in time, under Full Field Development (FFD), it is reasonable to expect that the Jurassic oil play will be revisited. If proven, this would add an entirely new dimension to Ntorya’s value.

---

Tanzania’s Strategic Positioning

Tanzania continues to strengthen its role as an emerging energy hub. Recent announcements of cooperation agreements with Russian firms on oil and gas data-sharing highlight how the country is seeking to attract wider international partnerships.

While this has no direct bearing on Ntorya’s near-term gas project, it underlines that global players are watching the basin — a positive backdrop for future growth and potential transactions.

---

The Bigger Picture for Investors

For Aminex shareholders, the significance is clear:

• Current discovered gas underpins near-term production and cash flow.

• Basin potential (16+ Tcf) could ultimately give Aminex’s 25% stake net exposure similar to what Cove Energy enjoyed at the time of its billion-pound sale.

• Oil upside offers an additional prize that is not priced into today’s valuations.

• Government and TPDC backing reduce financial risk on key infrastructure, keeping capital efficiency high.

---

Closing Thought

Ntorya today is about gas, CPF construction, and pipeline delivery. But Ntorya tomorrow could be about much more: multi-Tcf basin growth and the possibility of oil.

That dual track of secure near-term gas revenue and longer-term basin-scale upside is what makes the Ruvuma story compelling.

Just as Cove Energy’s 2012 sale proved, when majors see that scale — they act.

From Cove to Ntorya: What a Billion-Pound Gas Deal Could Mean for Aminex

How the Cove Energy sale in 2012 set a precedent — and what a cautious comparison suggests for Ntorya today.

---

Looking Back: The Cove Energy Deal

In 2012, Cove Energy became the centre of one of the oil and gas industry’s most closely watched bidding wars. The company held an 8.5% stake in Mozambique’s Ruvuma Offshore Area 1, where giant gas discoveries had been made.

Resource estimates at the time pointed to ~60–75 trillion cubic feet (Tcf) of recoverable gas in Area 1, giving Cove a net interest of around 5–6 Tcf.

Both Shell and PTTEP competed fiercely for the prize. PTTEP eventually secured Cove with a £1.2bn ($1.9bn) offer, equal to about £1.8bn in today’s money.

The message was clear: when majors see scale and strategic importance, they are prepared to pay significant premiums.

---

How Ntorya Compares Today

Tanzania’s Ntorya gas development is at a different stage and scale, but shares some important parallels:

• Onshore project with lower capital intensity, tied into the domestic grid.

• Gas Sales Agreement in place to supply 40 MMscf/d in the first year.

• Discovered resources of ~1.6–3.45 Tcf gas in place, equating to ~0.7–1.3 Tcf recoverable.

• Aminex 25% stake gives it ~0.4 Tcf net recoverable gas today.

• Pipeline funding covered by TPDC, reducing upfront capex risk for partners.

While smaller in absolute size than Ruvuma Offshore, Ntorya has the advantages of lower costs, faster route to market, and guaranteed domestic demand.

---

What a Yardstick Comparison Suggests

Cove’s 5–6 Tcf net stake was bought for £1.2bn. Aminex’s current discovered stake is smaller, but even if you apply Cove-style transaction multiples cautiously, it still points toward valuations in the hundreds of millions of dollars.

That compares with Aminex’s present ~£80m market cap — suggesting that as production ramps and reserves grow, there is room for meaningful upside.

---

Tanzania’s Strategic Context

Gas projects like Ntorya sit within a bigger picture. Tanzania is actively expanding its international energy partnerships, including a recent agreement to exchange data with Russian firms on oil and gas opportunities.

While this does not directly affect Ntorya’s early development, it underlines a key point: Tanzania’s energy sector is attracting global attention. That kind of strategic positioning can only strengthen investor confidence in the country’s long-term gas plans.

---

Why This Is Just the Beginning

The comparison above is based only on discovered gas at Ntorya today. It does not include:

• The 16+ Tcf unrisked potential identified in the wider Ruvuma Basin.

• The possibility of oil in deeper Jurassic horizons, hinted at during NT-2 drilling.

These longer-term opportunities could transform Ntorya into a basin-scale energy story — just as Ruvuma Offshore did for Mozambique.

---

Closing Thought

Cove Energy showed that majors will pay heavily for scale and strategic gas.

Ntorya is not Cove: it is onshore, domestic-focused, and nearer to revenue. But even on a cautious yardstick, Aminex’s stake already points to valuations above today’s market price.

And importantly, this is only the beginning. In our next article, we will explore the much larger upside potential — from multi-Tcf basin resources to the possibility of oil — and why Ntorya could ultimately prove far more significant than today’s numbers suggest.
