Two resources. One disciplined development model.
Steppe Nexus LLC is advancing the Shanagan project, distinguished by coal and humic material within the same licensed area, two development pathways from one project.

- Licensed area
- 887 hectares
- Coal classification
- Fat coal and semi-anthracite

≈ 87% of the coal reserve is classified as proven.
| Coal layer | Proven (kt) | Possible (kt) | Total (kt) |
|---|---|---|---|
| Layer 1 | 3,547.20 | 915.79 | 4,462.99 |
| Layer 2 | 2,085.50 | 112.04 | 2,197.54 |
| Layer 3 | 3,931.02 | 442.04 | 4,373.06 |
| Total | 9,563.72 | 1,469.87 | 11,033.59 |
From verified material to qualified products.
Independent laboratory reports (VUHU, Czech Republic; CTI, China) support continued product development. Reported humic acid content: 42–52%.
Humic raw material
For further downstream processing.
Humic acid powder
A refined agricultural input.
Potassium humate
Soluble product for soil and foliar use.
Liquid humic formulations
Formulated for application at scale.
An established mining and transport corridor.
Shanagan sits east of Ulaanbaatar within a working corridor, with access to Maanit railway station, Choir, and the Choir–Erlian route serving the China border.
Development advances through gated phases: Phase I establishes mine development and material control; Phase II introduces processing and product development, targeting up to 1.0 Mt/y washed coal and 30 kt/y humic products, subject to engineering and customer qualification.
Defined development targets, every one gated.
- 1.0 Mt/y
- Washed-coal target
- 30 kt/y
- Humic-products target
- 4,000–8,000
- Reported kcal/kg range
- 2026
- Overburden stripping commenced
Subject to engineering, financing, commissioning and customer qualification. Independent humic testing by VUHU (Czech Republic) and CTI (China).
Two distinct resources, one disciplined model.
- 01
Established legal basis
Mining licence MV-016990 covers an 887-hectare project area.
- 02
Defined coal reserve
Approximately 11.03 Mt of geological coal reserves, described as fat coal and semi-anthracite.
- 03
Differentiated humic potential
≈ 10 Mt of humic material with independently reported 42–52% humic acid content.
- 04
Sequential development progress
Exploration, licensing, feasibility approval, site preparation and initial stripping have advanced in order.
- 05
Multiple value-creation routes
Coal production can be developed alongside a separately qualified humic-product business.
Three seams, a complex structure, and a route to agriculture.
The deposit carries three main coal seams in a geologically complex setting, faulting, variable seam thickness and internal rock partings, which is why quality control and separate handling lead the mine plan.
For the group, Shanagan is more than a coal project: its humic resource is the feedstock base for Nexus Agro's route into value-added organic fertilizer products, qualified step by step from resource characterization through processing, agronomic testing and certification to commercial production.
