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 5: First Gas

 When molecules finally flowed to market

---

After years of drilling, licensing, and negotiating, the wait was over. In April 2016, Aminex announced that gas from the Kiliwani North-1 (KN-1) well had finally started flowing into Tanzania’s national grid.

It was a milestone not just for the company, but for the country. KN-1 marked the first time Aminex had moved beyond being a pure explorer and into the ranks of producing companies. Tanzania, meanwhile, gained a new domestic supply source to feed growing demand for power and industry.

The plan was a gradual ramp-up. Initial flows began at modest levels, with volumes increasing step by step over a 90–100 day commissioning phase until the system stabilised at around 25–30 million cubic feet per day. During that period, TPDC was invoiced monthly for gas produced, with payments made in advance under the security arrangements of the GSA.

For investors who had followed the company since the early Nyuni days, this was vindication. After more than a decade of waiting, Aminex could finally show a revenue line on its accounts — in hard US dollars.

It was also proof of concept. Gas from Kiliwani North flowed directly into the new Songo Songo processing plant and then into the pipeline system feeding Dar es Salaam. The whole chain — wellhead to processing to pipeline to end user — was now working. That mattered for the much larger discoveries in the Ruvuma basin, which would one day follow the same route.

For Aminex, first gas was the reward for persistence. For shareholders, it was proof that the long story of licences, partners, and patient waiting had a tangible outcome. But as so often in oil and gas, the story didn’t end there. Within a year, new challenges emerged.

➡️ Next time: Chapter Six — Challenges and Decline. We’ll follow the pressure problems that reduced KN-1’s flow, forcing Aminex to rethink its strategy and refocus on the bigger prize in the Ruvuma basin.

Aminex: From Acorn to Oak – Chapter 4: Gas Sales Agreement

The signature that turned gas into guaranteed dollars

---

By 2015, the pieces were lined up. Aminex had its discovery well, its government development licence, and Tanzania’s new processing plant and pipeline at Songo Songo were finally nearing readiness. What it still lacked was the most important piece of paper in any gas project: a sales contract.

That arrived on 13 January 2016, when Aminex announced that it had signed a fully-termed Gas Sales Agreement (GSA) with the Tanzania Petroleum Development Corporation (TPDC). For the company, it was the milestone shareholders had been waiting on for years.

The terms were clear, simple, and bankable:

• Price: US$3.00 per mmbtu (≈US$3.07 per mcf).

• Currency: Revenues in US dollars.

• Indexation: Annual adjustment using US CPI from 2016 onward.

• Structure: Take-or-pay depletion contract, ensuring TPDC had to either take delivery or pay for a minimum volume each year.

• Security: Monthly payments in advance, secured by letter of credit from Tanzania Investment Bank.

For a junior like Aminex, these terms were gold. Selling at the wellhead meant the joint venture partners didn’t shoulder pipeline or processing fees. The fixed dollar price insulated them from volatile global oil and gas markets. And the take-or-pay clause provided certainty that cash would flow even if volumes were lower than forecast.

It had been a long wait. The discovery was made in 2008, the development licence granted in 2011, and only now — eight years later — was Aminex in a position to sell gas. But when the GSA landed, it transformed the company overnight: a real producer in the making, not just an explorer.

For investors, this RNS was a watershed moment. Aminex had crossed the line from “exploration story” to “revenue story.” After years of patience, shareholders could finally expect the next announcement to be about gas flowing and dollars in the bank.

➡️ Next time: Chapter Five — First Gas. We’ll follow the moment molecules finally moved from the wellhead into Tanzania’s national grid, and Aminex booked its first ever production revenues.
