Operations at Rio Tinto's SimFer site in the Simandou iron ore project have been suspended following a worker fatality. This is the second such incident in less than a year, prompting a thorough investigation.

The Simandou project, a major untapped high-grade ore deposit, is targeting full production of 120 million tonnes/year. Rio Tinto had previously announced plans for the first shipment by November 2025, but this timeline is now uncertain due to the suspension.

RIO TINTO

Revenue Breakdown by Commodity (2024)

From consolidated net sales figures:

Iron Ore: 57.4%

Aluminum, Alumina & Bauxite: 24.2%

Copper: 8.8%

Industrial Minerals (e.g., titanium dioxide, borates, salts): 5.0%

Gold: 1.5%

Diamonds: 0.5%

Other (uranium, silver, zinc, molybdenum, etc.): 2.6%

HOW CAN RIO MITIGATE THEIR PILBARA DEPENDENCE

That’s an excellent clarification — let me restate with your correction:

1. Rio’s Iron Ore Dependence

~57% of Rio’s revenue comes from Pilbara iron ore, which is volume-rich but grade-declining.

This exposes Rio heavily to any structural shift in steelmaking demand away from 62% Fe fines.

2. Steelmaking Transition Risk

Blast Furnace (BF): Can process Pilbara Blend (~61–62% Fe).

Direct Reduction (DRI/HBI): Needs 67%+ Fe, low silica/alumina, for efficient hydrogen or gas-based steelmaking.

Problem: Pilbara ore doesn’t naturally meet DR specs → risks becoming discounted feedstock in a green steel world.

3. Simandou — Not a Perfect DR Solution

Simandou is high quality compared to Pilbara, but:

Surface ore averages ~65.3% Fe (not DR-grade).

Once shallow zones are exhausted, deeper material will require costly beneficiation to upgrade.

So while Simandou will still be premium relative to Pilbara, it is not a guaranteed DR-grade feedstock.

This limits Rio’s ability to rely on Simandou alone to plug its “green iron” gap.

4. Strategic Consequences if Rio Doesn’t Adapt

Loss of premium pricing: Pilbara ores face structural discounts vs. Vale’s Carajás or African DR-grade projects.

Earnings concentration risk: Copper, aluminium, and lithium aren’t yet large enough to replace iron ore’s profit engine.

Competitive gap: Emerging suppliers (Vale, African juniors, possibly BHP if they diversify into DR ores) will dominate green steel supply chains.

5. Trott’s Path to Rectify the Gap

Pilbara beneficiation: Invest in large-scale beneficiation + pelletising to upgrade fines into DR-grade pellets.

African expansion: Look beyond Simandou into true DR-grade deposits (e.g., Zanaga in ROC, Belinga in Gabon) that naturally offer 67–68% Fe.

Downstream integration: Build pellet/HBI plants near demand centres (MENA, India) tied to renewable hydrogen.

Diversification: Scale copper (Oyu Tolgoi, La Granja, Resolution) and lithium (Arcadium, Rincon) into true second/third revenue pillars.

✅ Corrected Conclusion:

Rio cannot assume Simandou solves its DR-grade problem — it peaks at ~65% Fe and will require beneficiation at depth. If the steel sector pivots decisively to hydrogen-based DRI/HBI, Rio’s current ore portfolio is structurally disadvantaged. Trott’s task is to:

Upgrade Pilbara ores,

Secure genuine DR-grade supply (via M&A in Africa or Brazil), and

Diversify into copper and battery metals to rebalance Rio’s overexposure to iron ore.

Guess how much I care about the opinions of the muppet sphere....

**Now (post-GIS deal):** * 20% is locked up with GIS (value ~$146m NPV at 3% fee). * But **80% is available** — far more flexible, and highly attractive to a Rio/Baowu/BHP JV.

> THIS IS THE NUB. HOW STRATEGICS NAVIGATE PAST THE GIS 20% PRECEDENT AND ZIOC CAN SECURE EARLY STAGE FINANCING:

ChatGPT said:

Exactly — you’ve got to the heart of it. The GIS deal “unlocks” ZIOC from the Glencore stranglehold, but it does set a precedent (20% of product already tied up, and the fee structure implied).

Here’s how strategics might navigate this, and how ZIOC can still structure early-stage financing:

1. GIS Precedent: Fixed Slice

GIS holds 20% of life-of-mine product marketing rights.

This slice is locked, so Rio/Baowu/BHP can only ever get access to the other 80%.

The implied valuation (~$146m NPV @3% fee) sets a benchmark — strategics won’t pay wildly above this, but they’ll factor in that the GIS deal wasn’t fully “arms-length” (so they could demand stricter terms).

2. Pathways for Strategics

Secure the 80%: Rio/Baowu could demand exclusive marketing over the remaining 80% in exchange for development capital and project leadership.

Cap GIS exposure: ZIOC can argue GIS rights are capped at 30 Mtpa plan, leaving any upside (expansions to 50–100 Mtpa) 100% available for the strategic investor.

Offset with equity stake: Strategics might say, “Fine, GIS has 20%, but we want a controlling project equity stake (40–50% JV) to secure volumes for our steel/iron ore portfolio.”

Use GIS as a customer channel: Instead of seeing GIS as a blocker, Rio could view them as a guaranteed Gulf/US buyer base, making Rio’s job easier in placing product.

3. ZIOC Early Financing Options

Sell part of the 80% rights now: If the GIS slice is worth ~$146m NPV, even 10% of the remaining 80% could bring ~$70m in upfront financing.

Staggered allocation: ZIOC can pre-sell tranches (5–10% rights) at feasibility/FEED milestones, bringing in stage-gated capital without surrendering full control early.

Expansion premium: Any rights beyond 30 Mtpa can be explicitly ringfenced for a strategic lead — a powerful sweetener for Rio/Baowu/BHP.

✅ Bottom Line

GIS deal costs $146m of marketing value, but it unlocked $584m of available rights to be monetised or used for strategic alignment.

Strategics can live with GIS 20% if they:

Get exclusive 80% rights,

Gain equity/project control,

Or ensure all future expansions (above 30 Mtpa) are fully theirs.

ZIOC can still use its 80% flexibility to stage-finance development before full JV — GIS is a nuisance, but not a deal-breaker.

I then fed the Nov 2022 Glencore marketing agreement to ChatGPT.

THIS IS VERY USEFUL — THANKS FOR POSTING THE VERBATIM TEXT.

Let me highlight the key economic and strategic implications of this Glencore life-of-mine Marketing Agreement and contrast it with the newer GIS offtake rights:

🔑 Key Features of the Glencore Agreement

Exclusive life-of-mine rights

Glencore had exclusive marketing rights to all iron ore produced at Zanaga, plus any other ZIOC/MPD iron ore in Congo using similar infrastructure.

This was effectively a total lock-up — no other party could access Zanaga’s product without going through Glencore.

Evergreen / binding

It continued for the life-of-mine unless terminated by breach.

ZIOC could not unilaterally revoke it.

Glencore fee structure

Glencore was entitled to an arm’s length marketing fee. While the fee % is not disclosed here, industry norms (iron ore marketing, especially high-grade niche products) run 2–5% of realised FOB price.

Revenue model

MPD/ZIOC received FOB sales proceeds once Glencore sold product to the final buyer.

In other words, ZIOC bore price exposure but not marketing execution.

Other ZIOC assets

Glencore also had the right of first refusal to market any other Zanaga-linked iron ore resources in Congo.

🔄 What Changed with GIS

Under the new structure (after the Glencore buyback), ZIOC allocated:

20% marketing rights to GIS (as part of Greymont Bay’s cornerstone investment).

The remaining 80% is free for ZIOC to allocate to other strategic partners.

Effectively, ZIOC cut Glencore out of exclusivity, freed up 80% for deal-making, but gave away 20% (to GIS).

⚖️ Strategic Implications

Before (Glencore deal):

Zanaga was heavily “encumbered.” Any major (Rio, BHP, Baowu) could not dictate offtake/marketing without negotiating with Glencore. This limited strategic interest.

Now (post-GIS deal):

20% is locked up with GIS (value ~$146m NPV at 3% fee).

But 80% is available — far more flexible, and highly attractive to a Rio/Baowu/BHP JV.

Downside: ZIOC had to “pay” by conceding 20% to GIS in order to free itself from a total Glencore stranglehold.

📌 Conclusion

The Glencore agreement was a major barrier to strategic development.

ZIOC’s restructuring traded 20% of marketing rights for the ability to sell 80% to the highest-bidding strategic investor.

While this does set a precedent valuation benchmark (future marketing rights will be compared to GIS), it is far superior to the Glencore lock-up, which made ZIOC essentially Glencore-dependent.

👉 Would you like me to quantify the “opportunity gain” here — i.e. compare the NPV of Glencore’s 100% lock-up vs. ZIOC’s current 20% GIS + 80% free structure?

ZIOC still retain 80% of the off take marketing rights, and I understand that these are lucrative for interested parties. However, we shall see whether this scenario is still possible, given the give away precedent set by the GIS deal.

ChatGPT:

Great. Let’s break it down step by step to estimate how much capital ZIOC could raise via a GIS-style marketing rights deal for its early-stage DRI production.

Step 1: Define the project production profile

From your previous inputs:

First production: 2030

Development period: 2026–2029

Annual production:

2030–2034: 12 Mtpa

2035–2059: 30 Mtpa

DRI grade iron ore price: $130/t in 2030, rising to $180/t over a decade

Step 2: Define the marketing rights deal

Assume ZIOC sells X% of the revenue on 20% of the project’s production:

GIS deal uses 3% of the retail price on 20% of production

Let’s also calculate for 2%, 5%, and 10% fees to understand range

Step 3: Calculate gross revenue from 20% of production

2030 first year example:

12 Mtpa × 20% = 2.4 Mt

Price = $130/t

Revenue = 2.4 Mt × $130/t = $312 million

GIS share (3% of retail) = 3% × $312M = $9.36M for 2030

Step 4: Capital-raising potential

Pre-sale of marketing rights is typically valued as NPV at the current date using ZIOC’s discount rate (10%).

For simplicity, if we take just the first 5-year period at 12 Mtpa, discounting $9.36M/year back 4–8 years (development period) gives roughly $36–40M upfront.

Extending to full production (30 Mtpa, 2035–2059) at escalating prices, NPV of 3% marketing rights across the whole 30-year project could be $146M (as we calculated earlier).

⚠️ This is the maximum theoretical amount ZIOC could raise upfront if investors are willing to pay full NPV for the future marketing rights. In practice, buyers usually offer a discount, so upfront cash might be 50–70% of the NPV.

Step 5: Sensitivity by fee level

2% fee → ~ $97M NPV

3% fee → ~ $146M NPV

5% fee → ~ $244M NPV

10% fee → ~ $488M NPV

Step 6: Practical takeaway

ZIOC could realistically raise $70–100M upfront via a GIS-style marketing rights sale at 3% of the 20% production revenue, enough to significantly de-risk early development and cover initial capital.

Selling too large a percentage (higher fees or higher production share) would limit upside for ZIOC shareholders and could be politically sensitive.

This takes some explaining.

MM: LET'S CALCULATE THE VALUE OF THE "ZIOC - GREYMONT BAY/GIS OFF TAKE DEAL" AS IF IT WAS A CURRENT ASSET, USING THE DISCOUNTED CASH FLOW METHOD.

Use 10% DR (ZIOC's rate)

4 years of development (26-29), first production 2030

Then 5 years at 12mtpa, then 25 years at 30mtpa

Current 68% price of $130/t rising to a projected $180/t over the next decade

GIS interest being 3% of the retail price (3% being a low estimate within the typical 2-10% range)

ChatGPT said:

Using your assumptions, the NPV of the GIS 20% offtake rights (3% fee on retail sales) is about:

$146 million (10% discount rate, in today’s money)

This treats the GIS agreement like a current asset:

No value during the 4-year development phase.

Revenue starting 2030, scaling from 12 Mtpa (5 yrs) to 30 Mtpa (25 yrs).

Iron ore fines price rising linearly from $130/t → $180/t over 10 years, then flat.

👉 THIS MEANS GIS’S SKIM IS WORTH ~$146M NPV

> So, and in return for providing $12.35m of cash now (for which they received 28.8% of ZIOC), the Greymont Bay consortium look to have also gained an asset worth c.$146m at current prices, i.e. the GIS off take deal.

>> If so then Greymont Bay have no finance cost on the GIS deal. In fact they could have already monetarised part of it. Were they have pre-allocated/sold just 10% of it they could have received c.$14.6m to put against the $12.35m they invested in ZIOC. If so and under this scenario 28.8% of ZIOC would have a *negative* cost of $2.25m.

>>> Scroll forward through development and into 2030 and production and the asset value of the deal is $214m. Of course, the applicable discount rate would also be much lower than 10% as Zanaga would be in production and the risks mostly mitigated, hence the asset value would be considerably higher again.

THE POINT BEING ......

What would ZIOC have done with $140m+ of cash? That is over 2x our current MCap. It would now be funding all current studies, then the company through FEED and ZIOC in a very strong negotiating position. At a guess our SP would be north of 50p.

And then there's this:

Clifford Elphick, Chairman of ZIOC, commented:

"I would like to thank Martin Knauth and Andrew Trahar for envisioning and structuring this entire process, driving the transaction and raising the capital."

Andrew Trahar's father, Tony, is one of the investors in Greymont Bay.
