Ovoot Coking Coal Project
Aspire Mining - Mongolia
Ovoot Coking Coal Project is under development and owned by Aspire Limited, located in Khuvsgul Aimag, Mongolia. O2 Mining has been providing consulting services to Aspire for development of this project since 2017.
Study Ovoot Phase 1, 2 & 3, PFS Update
Through our subsidiary, we completed an international standard pre-feasibility study announced by Aspire to the ASX in 2019.
Erdenet Rail Terminal Design
Later O2 was engaged by Aspire to design the Erdenet Rail Terminal for transhipment of coal from road train trucks into a coal storage facility, where coal is reclaimed and further loaded onto trains at a rate of up to 10 mtpa and this work was successfully completed in 2022. In 2024 O2 updated the ERT design to accommodate a new Phase 1 to Phase 2 expansion plan.

BED for Transport Hub and Offsite Infrastructure
In 2024 O2 was engaged to provide consulting services, including the preparation of an international standard design and cost estimate for the transportation hub and offsite infrastructure to support Aspire’s Ovoot Coking Coal project. Services comprised Basic Engineering Design for two truck rest stops strategically located along the transport route and a central transportation hub designed to support efficient and productive trucking operation. The transportation hub will serve as the centralised base for all trucking activity including routine inspections, scheduled preventative, maintenance, major overhauls, tyre changing and refuelling.

Kharmagtai Gold Copper Project
Xanadu Mines - Mongolia
Kharmagtai is a world-class, 30-year copper-gold mine in the South Gobi region of Mongolia that is under development by Xanadu Mines with investment and support from Zijin Mining. In 2022 O2 Mining was engaged to provide elements of the PEA with a focus on non-process infrastructure. Later O2 delivered an update to the PEA as being the overall QP for the work. In 2023 O2 commenced overall study management of the PFS. O2 created added value with introduction and execution and execution of CIL plant design, adding a further $120M to NPV and increasing IRR by 1.2% to bring in a further 8% of total gold recovery for the project.
O2 also played a key role in the project's implementation strategy, including the Project Execution Plan (PEP) and Operational Readiness Plan (ORP). Additionally, O2 contributed to the business and financial aspects of the study, including the development of the financial model for the PFS.

We provided turnkey air quality monitoring station solutions for the Kharmagtai Copper Gold Project at the project site. Incorporating air quality monitoring during the project design phase is essential for identifying potential environmental and health risks early. It allows project teams to establish baseline conditions, predict impacts, and integrate effective mitigation measures into the design. This proactive approach ensures compliance with regulations, protects local communities and ecosystems, and supports sustainable, responsible development from the outset.

Designing with clean air in mind means building responsibly from the ground up, protecting people, communities, and the environment before the first
shovel hits the ground.

O2 Mining installed two automated TSI Air Quality Monitors at the Bayan Khundii Project in partnership with Erdene Resource Development Corp. and its Mongolian subsidiary. These monitors provide real-time data to support dust suppression efforts and form the foundation for a robust Air Quality Management Plan, as part of the site’s Detailed Environmental Impact Assessment.
Local labour was engaged for the installation, fostering community involvement and raising awareness around air quality monitoring. The advanced TSI system measures PM1, PM2.5, PM10, total particulate matter, and gases including CO₂, CO, NO, and NO₂. This real-time data enables proactive risk management and enhances safety for workers and nearby communities.
This installation reflects O2 and Erdene’s strong commitment to environmental stewardship and opens the door for participatory monitoring to promote transparency and informed community dialogue.

Alluvial Gold Project
ODOD Gold Project - Mongolia
In 2019, O2 Mining subsidiary, SES Resources LLC secured an alluvial gold operations contract in Bayankhongor Province. We were able to mobilise only a few weeks after contract award, develop access into and set up a new site, and commence production. Mid season we finished mining on the first license and demobilised the camp and relocated to another license and commenced operations where we stayed through to the end of the season. By the end of the season, through our dedication and innovation, we had helped our client increase production threefold. And we achieved this without any recordable injuries (medical treatments or lost time injuries). We are exceptionally proud of what the team was able to achieve during the production season.

Chuluut International
Jonsh Tolgoi Project - Mongolia
O2 Mining has invested in a fluorspar project with Eurokhan and Chuluut International. We mobilised a team to refurbish existing equipment in the processing plant, assess conditions of the existing foundations and equipment, pull down the plant, re-design the processing plant to improve the efficiency of production, procure all new equipment to re-build and substantially complete all foundations for the installation of the new equipment. We ended the 2019 year with no recordable injuries, a great result given the complex and ever changing operations that were undertaken at the project site.
