An update to the Coal Reserve of Aspire Mining Limited (ASX: AKM)’s Ovoot Coking Coal Project, located in Mongolia, has been released by the company on 11 September 2026. And that updated number, just like in November 2024, is 130.1 million tonnes.
That reserve breaks down into 76.8 million tonnes Proved and 53.3 million tonnes Probable. When run through the processing plant, 97.9 million tonnes of it will be turned into premium coking coal, ready to sell.

The Reserve Number Didn’t Move. Everything Around It Did.
New consultant, same rock. Glogex Consulting LLC took over the review from SRK Consulting, with Mr Buyan-Ulzii Narankhuu signing off as Competent Person this time.
He didn’t visit the site. Mining hasn’t started at Ovoot yet, so there was nothing fresh on the ground worth inspecting.
Glogex wasn’t asked to remodel the deposit. The brief was narrower: check whether two years of project changes had quietly broken the mine plan. They hadn’t.
How Aspire Mining Cut the Ovoot Coking Coal Project’s Upfront Bill
Here’s the part that actually moves the needle for anyone watching AKM. The previous study assumed Aspire would buy its own mining trucks and excavators from day one of operations.
The new plan rents that fleet for the first three years instead.
Road haulage gets similar treatment. The trucks hauling coal from Ovoot to the rail terminal will be contracted for five years rather than bought outright, and a chunk of site infrastructure, camps, workshops, warehouses, gets deferred because some of it already exists and sits unused on site.
The forecast capital spend now breaks down like this:
- Phase 1 pre-production: US$61.2 million
- Phase 1 post-production: US$88.0 million
- Phase 2 expansion: US$71.2 million
- Sustaining capital over the mine’s life: US$1.037 billion
Compare that opening number to the old one. The 2024 study wanted roughly US$215 million spent before Ovoot earned a single dollar of revenue. This one wants US$61.2 million, plus US$24.6 million of working capital. Call it US$86 million all up, a funding gap cut by well over half, and it’s the biggest change buried in this announcement.
The NPV Actually Dropped, and That’s the Interesting Bit
A smaller capex bill usually pushes project value up. Ovoot’s post-tax NPV10 went the other way, sliding from US$1.58 billion in 2024 to US$1.48 billion now.
The reason sits in how those savings get funded. Aspire’s Mongolian subsidiary, Khurgatai Khairkhan LLC, plans to raise about US$126 million through bonds on the Mongolian OTC market, paying a 12% coupon every quarter plus a 3% broker fee on whatever gets raised.
Add roughly US$42 million of deferred payments owed to EPC contractor CCTEG-IEC, insured through China’s Sinosure, and the financial model is now carrying real interest and fee costs it never carried before.
So the trade is plain enough. Aspire gives up close to US$100 million of headline project value in exchange for a funding task that’s actually achievable for a company this size.
Nobody builds a coking coal mine in Mongolia by writing one big cheque, and this update reads like management accepting that reality rather than fighting it.
What Still Has to Go Right Before Ovoot Ships Coal
The EPC contract with CCTEG-IEC, worth US$69.9 million, is signed and covers the coal handling plant and the Erdenet Rail Terminal. That’s contracted pricing replacing old engineering guesswork, and it’s the main reason this update carries more weight than the last one.
The first coal is scheduled to be extracted in the December quarter of 2027, a year after initial predictions. From 1.5 million tonnes per year, production will go up to 2.5 million, and later on to 5 million tonnes once another processing module is installed.
The road remains the wildcard. Ovoot’s coal needs a new highway between the mine and the rail terminal, built and run under a public-private partnership with the Mongolian government, and that agreement still isn’t finalised.

Everything downstream of it, trucking costs, the toll, the whole logistics chain to China, depends on that deal landing on schedule. Aspire’s situation echoes what’s played out at Stanmore Resources’ Queensland operations, where weather and infrastructure timing swung a quarter’s numbers around just as much as the coal itself.
One more figure worth flagging for anyone doing their own sums. About 12% of the tonnes in the production schedule come from Inferred Resources, the least certain category under JORC rules, which by definition can’t sit inside a formal Reserve.
Most of that material is scheduled late in the mine’s 31-year life, so it barely touches the NPV even if none of it converts. But it’s there in the fine print, and coking coal pricing itself has swung hard before, as Peabody’s Queensland acquisition saga showed when a single mine incident rattled the whole deal.
For AKM watchers, the story hasn’t changed as much as the funding path wrapped around it. Same rock in the ground, same 130.1 million tonnes, same US$230-a-tonne coking coal price assumption borrowed from BHP’s own coking coal exposure in recent results commentary.
What’s different is how Aspire plans to pay for digging it up, and that plan now looks considerably more realistic for a company still building toward its first tonne of production.
