Jade Gas Eyes Deeper Stacked Gas Horizons Beneath Mongolia’s TTCBM Project
Key Takeaways
- Jade Gas Holdings is advancing a deeper exploration programme at TTCBM targeting CBM, shale gas, and tight sandstone horizons beneath its already-established shallower coal seams, with a structured seismic-first pathway before any deep drilling capital is committed.
- The company has received inbound inquiries from international energy companies regarding TTCBM's deeper gas potential — unsolicited third-party interest before a single seismic line has been acquired.
- Near-term priority remains the development and commercialisation of established gas resources at Red Lake, underpinned by Mongolia's first-ever formal natural gas reserves approval granted in June 2026.
- The Red Lake CBM development partnership is valued at $1.1 billion, providing a substantial commercial anchor against which the deeper exploration programme is being positioned as longer-term optionality.
- Jade draws on direct analogues from China's Ordos Basin — including the Linxing gas field and Daning-Jixian deep CBM development at depths exceeding 2,000 metres — to support the geological rationale for deeper targeting at TTCBM.
Jade eyes deeper gas potential beneath established TTCBM horizons
Jade Gas Holdings (ASX: JGH) is advancing a deeper exploration programme at its flagship TTCBM Project in Mongolia, targeting additional gas-bearing horizons that may lie beneath the established shallower coal seams the company is already developing. The initiative is complementary to Jade’s existing strategy, with near-term development and commercialisation of established gas resources at Red Lake remaining the priority. Adding weight to the case, the company has received inbound inquiries from international energy companies regarding deeper gas-bearing horizons at TTCBM, signalling broader industry interest before a drill bit has turned.

What the Ordos Basin tells us about stacked gas systems
To understand why Jade is looking deeper, it helps to understand how gas is distributed within coal-measure sequences. These are thick geological sequences that formed in ancient swampy environments, and they can host multiple distinct types of gas trapped at different depths.
The three gas types found in these stacked systems are:
- Coal bed methane (CBM): Gas adsorbed directly into coal seams (methane held within the coal itself, released when pressure is reduced)
- Shale gas: Gas trapped within fine-grained shale rock layers between or beneath the coal seams
- Tight sandstone gas: Gas held in sandstone reservoirs with low permeability, requiring more intensive extraction techniques
Jade draws on established examples from China’s Ordos Basin, particularly the Hedong Coalfield along its eastern margin. The Linxing gas field, historically developed by formerly ASX-listed Sino Gas and Energy, is the primary analogue. Exploration at Linxing identified multiple vertically stacked gas-bearing horizons within a broader coal-measure sequence, including CBM, shale gas, and tight sandstone gas. The Linxing experience demonstrates why evaluating the entire vertical gas system matters, rather than considering individual coal seams in isolation.
Further south along the eastern Ordos/Hedong trend, Daning-Jixian provides an example of deep CBM development, where gas has been successfully explored and developed from coal reservoirs at depths exceeding 2,000 metres. These analogues directly inform Jade’s decision to look beyond its currently targeted coal seams at TTCBM.
Seismic-first exploration pathway designed for disciplined target identification
Jade has outlined a structured, step-by-step exploration pathway designed to build geological understanding before committing capital to deep drilling.
- 2D seismic — broader structural and stratigraphic definition of the deeper geological sequence
- Targeted 3D seismic — higher-resolution imaging over selected areas
- Identify and rank prospective horizons — assess which deeper targets are most compelling
- Select priority targets — focus resources on the highest-conviction opportunities
- Deep exploration drilling — test the identified targets
- Reservoir and gas evaluation — assess the commercial potential of any discoveries
The logic here is straightforward: 2D seismic is lower cost and maps the broader picture first, allowing Jade to identify where higher-resolution 3D imaging is warranted. Committing to deep drilling without this seismic foundation would mean selecting well locations without adequate geological support, an expensive way to take unnecessary risk.
The company also notes that establishing a high-quality seismic dataset will provide a stronger basis for progressing discussions with the international energy companies that have already made inbound inquiries.
Ian Wang, Executive Director, Jade Gas Holdings
“We already know that TTCBM hosts an established coal-measure gas system, and our focus is now on understanding how much further that system may extend at depth… The inbound inquiries we have received from international energy companies regarding TTCBM’s deeper gas potential reinforce our view that this is an opportunity worth investigating. The seismic program will provide the geological definition needed to identify and rank deeper targets before committing to exploration drilling…”

Investment case: near-term development backed by longer-term upside
The investment case here operates on two distinct time horizons, and it is worth separating them clearly.
Near-term, Jade’s priority remains the development and commercialisation of its established gas resources at Red Lake within the TTCBM Project. This is not speculative — the company transitioned from explorer to developer following Mongolia’s first-ever formal natural gas reserves approval in June 2026, and it operates the project through subsidiary Methane Gas Resource LLC (MGR), a joint venture with the Mongolian Government. Jade also holds a CBM JV with Hong Kong-listed Mongolia Mining Corporation (MMC) over the BNG Project, adjacent to TTCBM.
The Red Lake CBM development partnership, valued at $1.1 billion, provides the commercial scaffolding against which the deeper exploration programme is being positioned, with near-term gas monetisation at Red Lake remaining the anchor of Jade’s overall project strategy.
Longer-term, the deeper exploration programme layers optionality onto that existing foundation. The inbound interest from international energy companies adds credibility to the thesis without requiring Jade to have drilled anything yet. If seismic programmes confirm compelling deeper targets, the company intends to use those results to optimise the location and design of future deep exploration wells.
The announcement also notes that identification of material deeper gas targets may provide additional technical information relevant to Jade’s proposed Hong Kong listing and its engagement with Asian strategic, institutional, and energy-sector investors.
| Project | Location | Structure | Current Stage | Deeper Exploration Status |
|---|---|---|---|---|
| TTCBM Project | Mongolia (South Gobi) | Production Sharing Agreement (PSA); JV with Mongolian Government via MGR | Development and commercialisation of established gas resources at Red Lake | Deeper programme planned; 2D and 3D seismic to define targets |
| BNG Project | Adjacent to TTCBM, Mongolia | JV with Mongolia Mining Corporation (MMC) | Further appraisal and commercial pathway assessment | Not referenced in this announcement |
The seismic-first approach positions Jade to understand the full scale of the TTCBM system before making capital commitments on deep drilling. Whether the deeper system proves material remains an open question, but the programme is designed to answer it in a disciplined, cost-sequenced way.
