Mongolian Mining（蒙古焦煤，00975.HK）: A Company You Can't Price, at a Price You Shouldn't Pay
A coking coal miner bolting on a gold mine, a government eyeing 60% of the economics, and a stock trading at twice my expected value.
Mongolian Mining digs coking coal in the Gobi Desert, trucks it 240 kilometers to the China-Mongolia border, and sells it to Chinese steel mills. In September 2025, it added a second leg — a gold mine called Bayan Khundii came online. The market re-rated it from a pure-play coal cyclical into a “diversified mining platform.” The stock went from HKD 0.50 in 2021 to HKD 14.78 at its peak — nearly 30x. Then coal prices collapsed, the gold mine underdelivered, and the Mongolian government started talking about a new tax. It halved to HKD 5.90, then bounced to HKD 8.99 today.
My conclusion: HKD 8.99 is too expensive. My best-effort expected value is around HKD 4.35 per share. If I haircut that by half for the sheer number of unverifiable assumptions baked in, the no-brainer entry price is roughly HKD 2.10 — a level the stock traded at in mid-2023. Not ancient history.
The Coal Business: A Narrow Sliver of Profit You Can’t Control
Coal is 96% of revenue. The operations are fine — the mines have been running for over a decade, the wash plant churns out about 9 million tonnes of saleable coal a year, and the cost structure is well-documented at roughly USD 53 per tonne delivered to the border. None of that is in dispute.
The problem is that coal mining is a fixed-cost business. Revenue minus a wall of immovable costs leaves a thin sliver of profit. And the three variables that determine how wide that sliver opens are all completely outside MMC’s control.
The first variable is what price the coal fetches. Blended ASP was USD 121/t in 2024 and crashed to USD 82/t in 2025. Over a ten-year lookback, the through-cycle midpoint for MMC’s product mix is roughly USD 85–115/t. Every USD 10/t swing moves annual owner earnings by about USD 63 million. Multiply that by a 5x cyclical multiple and you get a USD 315 million valuation swing — from a single input. The dashboard assumes USD 102/t as the normalized midpoint. I think that’s optimistic. China’s crude steel output has fallen from 1.065 billion tonnes in 2020 to 961 million in 2025 and is still declining. If that decline is structural — driven by the permanent shift from real estate to manufacturing as the primary source of steel demand — the coking coal demand base isn’t coming back, and the ASP midpoint should be closer to USD 88–95.
The second variable is how much the Mongolian government takes. The ordinary royalty of 5–8% of revenue is already baked in. But in February 2026, the government signed a non-binding MoU proposing that it receive 60% of “cumulative economic benefits” from the mines, replacing a threatened 34–50% free equity stake with a market-price-linked special royalty instead. The precise formula has not been disclosed. If “60%” includes all existing taxes, royalties, and interest payments the company already makes, the incremental burden could be trivial — an extra 1–2% of revenue. If it’s layered on top of existing obligations at 5–8% of revenue, it would drain USD 30–50 million per year from owner earnings and effectively cap shareholder upside in any coal upcycle. This is a binary event: the day the final agreement is published, a huge chunk of valuation uncertainty collapses overnight.
The third variable is how much it costs to keep the mine running. Open-pit coal mining requires continuous stripping — removing the overburden rock sitting on top of the coal seams. This is real cash expenditure that doesn’t show up in EBITDA but absolutely shows up in free cash flow. The bill was USD 93 million in 2023 and has risen to USD 128 million in 2025. The dashboard assumes USD 100 million as the mid-cycle norm. That looks stale. Add USD 40 million for sustaining equipment replacement, and you’re looking at USD 160–170 million in annual maintenance capex before a single dollar reaches shareholders.
I probability-weighted these three variables across their plausible ranges and ran the numbers ten thousand times. The expected annual owner earnings come out to about USD 74 million — roughly half the dashboard’s USD 155 million midpoint. Not because any single assumption is extreme, but because the operating leverage in this business amplifies small input deviations into large profit swings. A 4% revenue miss, plus a new royalty layer, plus slightly higher stripping costs — each one modest on its own — combine to cut OE nearly in half. At a 5x multiple, the coal business is worth roughly USD 370 million in my framework, versus USD 775 million in the dashboard’s.
The Gold Mine: One Number Decides Everything
Bayan Khundii produced its first gold in September 2025. The wash plant works — Q1 2026 throughput hit 94% of design capacity. Recovery rates exceeded the feasibility study assumption at 96%. Engineering risk is largely behind us. This is a real mine, not a PowerPoint.
But the grade is wrong. The feasibility study projects a life-of-mine average of 4.0 grams per tonne. Actual feed grade in Q1 2026 was 1.9 g/t, rising to 2.7 g/t by March. Management says this is normal ramp-up — the current mining face is in a lower-grade zone, and the geological model predicts improvement as the pit advances into the core orebody. That explanation is plausible. It’s also exactly what every mining management team says when early grades disappoint.
Grade matters more than anything else at BKH because the wash plant’s capacity is denominated in tonnes of rock, not grams of gold. Processing costs are roughly the same whether a tonne of ore contains 4 grams of gold or 2 grams. At 4.0 g/t, annual output is about 78,000 ounces; at 2.0 g/t, it’s 39,000. Revenue halves. Costs don’t move. Profit swings by a factor of three.
The breakeven grade is only about 0.8–1.0 g/t at current gold prices, so BKH won’t shut down even if grade stays low. But the difference between 4.0 g/t and 2.5 g/t is the difference between a USD 400 million asset and a USD 150 million asset. That’s not a rounding error.
There’s also a structural wrinkle: MMC owns 50% of Erdene Mongol, the joint venture that operates BKH. But MMC is simultaneously a creditor — it has lent EM about USD 73 million, on top of a USD 50 million bank loan from TDB. Cash flow from the mine must first repay TDB, then repay MMC’s shareholder loan, and only then does the residual equity get split 50/50 with partner Erdene Resource Development. In the early years this structure actually favors MMC — it collects as a senior creditor before Erdene sees a dime of equity distributions. But it means you cannot simply take 50% of the project NPV and call it MMC’s share. You have to run the waterfall. After running it at a conservative 3.0 g/t grade and current gold prices around USD 4,200/oz, I get roughly USD 300 million as MMC’s look-through value. The dashboard’s base case at full FS grade and a lower long-term gold price gives USD 323 million — remarkably close, but arrived at from different directions.
Copper and Silver Options: Having Rock in the Ground Is Not the Same as Having a Mine
In March 2025, MMC paid USD 20.5 million for 50.5% of Universal Copper, which holds exploration-stage copper, silver, and gold projects in Mongolia. The resource estimates are real — drill holes were drilled, core samples were assayed, independent qualified persons signed off. Copper is there. Silver is there.
But from “there’s metal in the ground” to “we can profitably extract and sell it” is a long road with many off-ramps. There is no feasibility study, no proven reserve, no confirmed metallurgical process, no capex estimate, no water or power infrastructure plan, and no financing. In the copper project, arsenic contamination in the ore could complicate processing. In the silver project, over 60% of the resource is classified as Inferred — the lowest confidence category, meaning the drill holes are too sparse to say much beyond “something is probably there.”
The dashboard applies a probability-weighted NPV and arrives at USD 55 million for MMC’s share. I’d anchor closer to the acquisition price — if a knowledgeable buyer and seller agreed on USD 20.5 million for 50.5% after due diligence, that’s a real market data point. No milestone has been achieved since to justify a 2.7x markup. But frankly, whether you use USD 25 million or USD 55 million barely matters — it’s noise in a company where coal alone swings by USD 350 million depending on your ASP assumption.
Putting It Together
After subtracting roughly USD 138 million in net debt — the USD 350 million Senior Notes due 2030 at 8.44%, less cash on hand — total equity value comes to about USD 586 million, or HKD 4.35 per share. The current stock price of HKD 8.99 implies a market cap of approximately USD 730 million, about 25% above my expected value. To justify HKD 8.99, you need coal to be worth north of USD 850 million — which requires the ASP midpoint, the government’s tax take, and the stripping bill to all break favorably at the same time.
The stock traded at HKD 0.50 in 2021 and at HKD 2.10 in mid-2023. Those prices turned out to be far too cheap — the company survived, coal prices surged, BKH got built, debt got refinanced. But recognizing that the stock was cheap at HKD 2 is not the same as concluding it’s cheap at HKD 9. The fundamental picture has genuinely improved — BKH adds real value, the balance sheet is healthier, gold prices have more than doubled. I estimate those improvements are worth roughly HKD 2–3 per share on top of the old base. That gets you to HKD 4–5 as a fair reflection of the better fundamentals. The remaining gap to HKD 9 is the market paying for a narrative — “diversified mining platform” — that hasn’t been verified yet.
Verdict: Watchlist. Don’t buy, don’t short, wait for the price to give you a margin of safety.
