Steppe Gold Ltd (TSX: STGO) (OTCQX:STPGF) (FSE:2J9) ("Steppe Gold" or the "Company") is pleased to announce the positive results of the Feasibility Study on the 100% owned ATO Gold Project in Mongolia (the "Feasibility Study"), comprising a further two years at the producing oxide phase and a 10.5 year expansion ("Phase 2 Expansion"), for a 12.5 year aggregate mine life. The results reinforce the Company's current Phase 2 Expansion plans with construction already underway, and existing permitting and infrastructure in place.
All amounts are in US dollars unless otherwise indicated.
- Pre-Tax NPV (5%) of $320 million with an IRR of 109% and a Post-Tax NPV (5%) of $232 million with an IRR of 67%, driven by rapid payback of three years from initial capital outlay
- Total gross revenue of $1.72 billion and EBITDA of $584 million over 12.5 years, with first concentrate production anticipated in Q4 2023.
- 106k oz of annual gold equivalent ounce production in years 1-5 of the Phase 2 Expansion, following depletion of the oxide zone
- Average site AISC of $853/gold equivalent ounces, with solid plans to optimize, notably with grid power
- Initial capital expenditure, prior to optimisations, is expected to be $128 million (including a $12 million contingency)
- Phase 2 Expansion assumes processing 2.2 million tonnes per annum incorporating crushing, grinding and flotation of concentrates
- Gold recovery is forecast to be 79% with further recoveries of up to estimated 10% through CIP/CIL plant in later years
Mr. Bataa Tumur-Ochir, President and CEO commented, " Following our highly encouraging resource update earlier this year, we are very pleased to share the Feasibility Study results. These results reinforce Steppe Gold's commitment to creating shareholder value from our exciting and growing portfolio of precious metal assets. We are confident that our flagship asset, the ATO Gold Project, will deliver significant upside for all stakeholders with the robust economics from this project and infrastructure already in place.
The 2021 Feasibility Study highlights a positive economic project for the Phase 2 Expansion at the ATO Gold Mine. This has confirmed an expanded life of mine to 12.5 years producing gross revenues of $1.72 billion, EBITDA of $584 million with an initial capex of $128 million and site AISC of $853/oz of Au Eq.
With a conservative metal prices modelled, including $1,610 per gold ounce, the ATO Gold Project is shown to deliver a solid set of results, featuring strong cash flows and a rapid payback of capital.
Importantly, Steppe Gold has already started construction work which will benefit the Phase 2 Expansion, with a new 2.5Mt per annum fixed crusher now being installed and expanded infrastructure underway. The Phase 2 Expansion project has all major permits in hand and we anticipate first concentrates in Q4 2023.
We have numerous plans underway to further optimize the Phase 2 Expansion to include planned connection to grid power, optimization of construction and engineering costs, and further exploration and remodelling to support higher conversion of resources to reserves.
Furthermore, with planned production in 2022 and 2023 for a total of 100k oz, at Site AISC of $687/oz, from the oxide zone we have a strong position to source the required additional capital.
As communicated in previous shareholder updates, discussions with project lenders are advancing. Timely debt financing will allow the Phase 2 construction that is already underway, to continue uninterrupted."
Mr. Matthew Wood, Executive Chairman commented, " This very exciting study supports our long held view that the ATO Gold Project would show strong economics at conservative metal prices. We consider this to be a strong base line economic view for the project as currently scoped but we are most excited about the plans underway to continue improving on the scope, scale and economics of the project with expanded drilling, interpretation, cost savings measures and optimization of processing. We know we can improve on gold recovery overall and we have still only scratched the surface of the precious metals potential at the exciting Mungu deposit."

The technical report related to the Feasibility Study results will be filed on SEDAR within 45 days, in accordance with National Instrument 43-101 ("NI 43-101") The study has been prepared with input from the following independent consultants:
|The study has been prepared with input from the following independent consultants:|
|DRA Global Ltd||Mining, Mineral Reserves, Geochemistry, Processing Plant and Infrastructure|
|Ulzii Environmental LLC||Environmental and Social|
|Knight Piésold Pty Ltd||Tailings Facilities, Hydrology and Tailings Facility Geotechnical|
|DRA Global Ltd and CRU Consulting||Economic Evaluation / Financial Modelling|
The TSF has been designed by Knight Piésold Pty Ltd to ANCOLD guidelines and the Global Industry Standard on Tailings Management (GISTM). The TSF will comprise an initial starter cell of 3.6 Mt (18 month capacity) and with a final capacity of 14.8 Mt at an average annual throughput rate of 2.38 Mt/y. Subsequent to Stage 1, the TSF will be constructed in annual raises to suit storage requirements, however this may be adjusted to biennial raises to suit mine scheduling during the operation.
The ANCOLD Dam Failure Consequence Category is identified as ‘High C' on the basis of a potential population at risk in the range of ‘≥1 to
The TSF is located in a south-east facing valley approximately 2 km south-east of the pit and will comprise a high-density polyethylene (HDPE) lined cross-valley storage facility formed by multi-zoned earth fill embankment. Downstream raise construction methods will be utilised for all TSF embankment lifts. Construction materials for the TSF embankment will be principally sourced from local borrow material within the basin area and mine waste.
Tailings will be discharged into the TSF by sub-aerial deposition methods, using a combination of spigots at regularly spaced intervals from the TSF embankment and other specified locations, to locate the supernatant pond at the decant towers.
The site experiences low rainfall and average temperatures are below freezing for five (5) months of the year (November to March). A decant return / process water shortfall is expected to occur under average and design dry climatic conditions and all make-up water requirements will be provided by groundwater abstraction from the borefield.
As part of the operation of the TSF, extensive monitoring of all aspects of the operation should be undertaken.
The estimated capital costs for the Phase 2 Expansion of the ATO Project were primarily built up from quotations and proposals from equipment and service providers. The Feasibility Study costs currently assume a contract mining fleet. All financial analysis for the Life of Mine includes the total design, construction and commissioning, production, and closure.
The Feasibility Study work has been completed based upon the development of the Phase 2 Expansion of the ATO Gold project with minimal tonnage from the Mungu deposit. Further exploration and development work on the Mungu resource, with an effective date of March 30, 2021, could further extend the life of the operation while utilising the same infrastructure and processing capabilities already in operation.

NON-IFRS PERFORMANCE MEASUREMENT
Non-IFRS Performance Measurement: Earnings before interest, taxation, depreciation and amortisation ("EBITDA") and all-in sustaining cost (AISC) are non-IFRS performance measurements. C1 cash costs and AISC are included because these statistics are widely accepted as the standard of reporting cash costs of production in North America. These performance measurements do not have a meaning within IFRS and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measurements should not be considered in isolation as a substitute for measures of performance in accordance with IFRS.
The health and safety of our employees, contractors, vendors, and consultants is the Company's top priority. In response to the COVID-19 outbreak, Steppe Gold has adopted all public health guidelines regarding safety measures and protocols at all of its mine operations and corporate offices. In addition, our internal COVID-19 Taskforce continues to monitor developments and implement policies and programs intended to protect those who are engaged in business with the Company.
Through care and planning, to date the Company has successfully maintained operations, however there can be no assurance that this will continue despite our best efforts. Future conditions may warrant reduced or suspended production activities which could negatively impact our ability to maintain projected timelines and objectives. Consequently, the Company's actual future production and production guidance is subject to higher levels of risk than usual. We are continuing to closely monitor the situation and will provide updates as they become available.
