Disclosure: S3 Consortium Pty Ltd (The Company) and Associated Entities own 4,895,000 MNB shares and 1,562,500 options at the time of publishing this article. The Company has been engaged by MNB to share our commentary on the progress of our investment in MNB over time.

Our African food security investment, Minbos Resources (ASX:MNB), is set to benefit from record fertiliser prices at a time when the world is desperate for new supply.

In fact, prices are so high that MNB is planning to alter its plant configuration in its Definitive Feasibility Study (DFS) so that it can maximise the economics of its low CAPEX project.

Today’s move by MNB takes place within the context of tectonic ruptures in the food supply chain.

Africa’s food security was already under threat due to the pandemic.

Then, in October 2021, China moved to ban the export of phosphate (a key fertiliser ingredient) until June 2022 (we expect that ban to continue).

Next, the war in Ukraine sent fertiliser prices flying as Russia moved to suspend fertiliser exports.

According to the The Fertiliser Institute, Russia is the world’s largest exporter of fertilisers.

The country accounts for 23% of ammonia exports, 14% of urea exports, 10% of processed phosphate exports, and 21% of potash exports.

With no end to the war in sight, and the political and economic fallout likely to continue for years, if not decades, we think fertiliser prices could remain elevated for a prolonged period.

Which is why we’re of the view that MNB’s announcement today is a strong net positive - it pushes back the timetable for the DFS (our #1 Key Objective) from Q2 2022 to Q3 2022, in exchange for the ability to capture even more value from the project.

Crucially, MNB’s plant commissioning is still on track for H1 2023 - nothing has changed with regards to the production start date.

In light of this, today’s note will cover the following:

  1. Key pieces of information in today’s MNB announcement
  2. MNB’s project economics and record fertiliser prices
  3. What makes MNB’s project unique?
  4. How today’s announcement de-risks our MNB position
  5. Bonus: highlights from Argonaut’s recent site visit
  6. Our MNB Investment Memo

Ultimately, we’re invested in MNB to see it reach production - which is reflected in the “Why we continue to hold MNB in 2022” section of our Investment Memo (click the image below to access):

More on today’s announcement

ASX MNB Investment Memo

Today’s announcement directly impacts Key Objective #1 on our 2022 MNB Investment Memo.

The DFS will be pushed back from previous MNB timelines to Q3, but we think it will be improved - more on that in the next section.

For now though, here are the key pieces of information as we see it:

  1. MNB’s plant commissioning is still on track for H1 2023 - nothing has changed with regards to the production start date
  2. Full utilisation of the plant may be accelerated
  3. The macro forces behind MNB’s product mean the DFS economics should improve
  4. In turn, this should make financing even easier

And here’s the key quote from MNB CEO Lindsay Reed:

MNB’s project economics and record fertiliser prices

Today’s announcement by MNB comes as fertiliser prices are moving towards all time highs.

Prices for raw materials that make up processed fertilisers (ammonia, potash, phosphates, sulphur) have risen 30% since the start of the year.

MNB’s Scoping Study was completed in 2020 - the world was a different place then.

The financial metrics of the project were calculated using a using a US$357-482 per tonne phosphate price (MAP price), which gave the following project economics:

  • Post-tax NPV of US$191-308M (A$260-420M).
  • Low upfront CAPEX of US$22-28M (A$30-38M).
  • 21 year mine life.

MNB also released a best-case scenario with phosphate prices at US$643/tonne where the after-tax NPV was US$343M.

MNB’s input price in the Scoping Study (MAP) trades at a +-5% price to DAP (Diammonium phosphate). Fertiliser prices are now trading at multiples of the figures MNB used in its Scoping Study, with prices >US$1,200/t.

The sensitivity analysis in the Scoping Study showed that for every ~10% increase in the fertiliser price, the pre-tax NPV would increase by ~US$50M.

With prices up almost 200% we think the current project economics are likely to be significantly stronger now.

 Scoping Study; sensitivity analysis

Of course, we have also seen plenty of inflationary pressures in supply chains. So some of the gains are likely to be offset by cost escalations in the operating and capital costs for the project, like buying steel to build the plant.

The net positive being that MNB when it delivers its DFS in Q3 of this year we think it will be able to show vastly improved project economics.

What makes MNB’s project unique?

A lot of the recent media coverage has been fixated on the issues of food security and the potential for shortages globally. See this article from the BBC: Scottish farmers warn of rising costs and food shortages.

This has put a spotlight on fertiliser supply as the agricultural sector is primarily dependent on being able to secure cost effective fertiliser to improve crop yields (output of the raw materials that are used to produce the food we consume).

This naturally leads us to the questions of ‘why’ all of this is happening.

We think that the problems are mostly related to the following:

  1. The supply chain disruptions caused by the shutting out of Russia from the global economy - Russia was the world’s biggest exporter of fertilisers in 2019 and is a key supplier of urea and potash.

  2. The input costs to produce fertiliser and food are increasing - This is more so related to the rising energy costs. The cost of natural gas is significantly higher versus the same time in 2021 and the oil price is trading just shy of ~10 year highs.

The first issue is relatively well understood, but the second is far less obvious. Almost everything that we use in daily life requires energy during its production process. Fertiliser and subsequently the foods we consume are no different.

With energy costs increasing the natural flow on effect is that the cost of producing fertilisers and food goes up, this coupled with the major supply chain issues leads to shortages, increasing prices even further.

This is where MNB’s project’s strengths start to shine through, mainly because of its location in Angola.

First of all Angola has an abundance of renewable energy capacity with over 1,000MW of hydropower available, this means Angola ranks second for the cheapest source of electricity on the planet.

The significance of this is that when MNB gets the project into production, it will benefit from having low input costs, and will also be producing with a low carbon footprint.

Second, MNB is located to the south of Europe, in Africa making it the ideal solution to solving the supply side issue caused by sanctions on Russia. MNB will be benefiting from both local demand increasing and the European interest for its product.

MNB will therefore not only benefit from increasing local demand in Africa but also benefit from the European Union's requirements to look for alternate supply sources as it tries to diversify away from Russia.

With competitive input costs and the project expected to be construction ready in 2023, MNB could potentially be a few years away from producing and supplying into key export markets like the EU.

How today’s announcement de-risks our MNB position


The above two risks are closely linked. As the underlying commodity (fertiliser) price rises, the economics of MNB’s project improve, in turn making funding more readily available.

We’re of the view that these two risks are being addressed in tandem, and today’s announcement further de-risks our MNB position.

After reviewing the notes from Argonauts site visit, it's pleasing to see infrastructure improvements going into the Angolan landscape that MNB will operate in.
