1. The Statement of Estimates of Mineral Resources has been compiled under the supervision of Mr. Oyunbat Bat-Ochir who is a full-time employee of RPM and a Member of the Australian Institute of Geoscientists. Mr. Bat-Ochir has sufficient experience that is relevant to the style of mineralization and type of deposit under consideration and to the activity that he has undertaken to qualify as a Qualified Person as defined in the CIM Standards of Disclosure.
2. All Mineral Resources figures reported in the table above represent estimates at November 1, 2022. Mineral Resource estimates are not precise calculations, being dependent on the interpretation of limited information on the location, shape and continuity of the occurrence and on the available sampling results. The totals contained in the above table have been rounded to reflect the relative uncertainty of the estimate. Rounding may cause some computational discrepancies.
3. Mineral Resources are reported on a dry in-situ basis.
4. The Mineral Resource is reported using a 0.35 g/t Au cut-off grade in oxide and transition mineralisation and 1.02 g/t Au cut-off in fresh mineralisation and is constrained above conceptual optimised pit shell. Cut-off parameters were selected based on an RPM internal cut-off calculator, assuming an open cut mining method with 5% ore loss and 10% dilution, a gold price of US$1,723 per ounce, a mining cost of US$3 per tonne and a processing cost of US$16 per tonne milled and processing recovery of 90% for oxide, 87% for transitional and 30% for fresh Au mineralisation. The conceptual optimised pit shell was constructed using a gold price of US$2,000 per ounce, which is 1.4 times the long-term consensus forecast price.
5. Mineral Resources referred to above, have not been subject to detailed economic analysis and therefore, have not been demonstrated to have actual economic viability.

BK and DH Reserve Estimate

The Bayan Khundii and Dark Horse FS Mineral Reserves have been estimated by QP, Mr. Julien Lawrence, Director, O2 Mining Limited, using the 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves to conform to the Canadian National Instrument 43-101 Standards of Disclosure for Mineral Projects. The total Mineral Reserve for the Bayan Khundii deposit is shown in Table 5 and the total Mineral Reserve for the Dark Horse Mane deposit is shown in Table 6. Mineral Reserves are based on the BK Mineral Resource and Dark Horse Mineral Resource, reported herein. Mineral Reserves estimated for the BK and DH deposits are based on Measured and Indicated Resources and have an effective date of August 1, 2023. Reserves were calculated by O2 Mining using FS level engineering designs for the pit and associated process plant operating parameters.

The cut-off grade for mineral reserve calculations is 0.63 g/t gold for the BK Gold Deposit and 0.68 g/t gold for Dark Horse Gold Deposit, based on a gold price of $1,816/oz. The reserves, as defined by the regularized block model, contain modelled mineral losses of 2.5% and average internal dilution of 10%, within the ultimate pit.

A summary of the Mineral Reserves estimated for the BK and Dark Horse deposit with an effective date of August 1, 2023 can be found in Tables 5 and 6.

Table 5. BK Gold Deposit – Mineral Reserve Estimate Summary, August 1, 2023

Notes:

1. The effective date of the Mineral Reserve estimate is August 1, 2023. The QP for the estimate is Mr. Julien Lawrence of O2 Mining Limited;
2. The Mineral Reserve estimates were prepared with reference to the 2014 Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards (2014 CIM Definition Standards) and the 2003 CIM Best Practice Guidelines;
3. Reserves estimated assuming open-pit mining method;
4. Waste to ore cut-offs were determined using a NSR for each block in the model. NSR is calculated using prices and process recoveries for each metal accounting for all off-site losses, transportation, smelting and refining charges;
5. Reserves are based on a gold price of $1,816/oz; and
6. Mineral Reserves were calculated from a diluted “mining” block model which included average dilution of 10% and losses of 2.5%.

Mining

The BK FS is based on an open-pit mining operation targeting 650,000 tonnes per year of feed material for the processing plant. The total mineable mineralized plant feed is 4.0 million tonnes at an average diluted head grade of 4.0 g/t gold and average strip ratio of 10.9:1 (waste tonne: plant feed tonne). Mineralization starts at surface, with the majority of the deposit contained within the top 100 metres. The deposit structure, grades and depth suggest selective open cut mining will be utilized. Mining will use hydraulic excavators in backhoe configuration. Drilled and blasted material will be loaded into haul trucks, with waste rock deposited in an engineered Integrated Waste Facility (“IWF”) adjacent to the pit, and ore hauled to a crusher or run-of-mine (“ROM”) pad adjacent to the processing plant.

The BK FS has assumed owner mining based on methodology and costing prepared from first principles using vendor quotations for major cost elements and O2 Mining experience in Mongolia in similar open-pit mining environments. In this scenario, the owner leases the major fleet and provides for all minor fleet and personnel to operate the project. The mine plan proposes a total of 4 x excavators (2 x ore, 2 x waste), 20 x 55t payload trucks, 3 x blasthole drills and a fleet of ancillary and support equipment to deliver the required material movement. The mining workforce peaks at approximately 260 personnel (employees and contractor personnel) to deliver the required schedule of production.

Processing

The FS assumes processing of ROM material via a conventional crush and grind circuit and a carbon in pulp plant. Plant design by 360-Global has been based on testing at Blue Coast Research which has established optimal processing parameters, including; grind size of 80% passing 60 microns; design inputs for comminution circuit, optimal cyanide concentration in leach circuit; 36 hour retention time; carbon adsorption parameters and detoxification reagent dosages. The process circuit has been designed to maximize water recovery with the most efficient dewatering process (pressure filters) to achieve targeted 15% moisture in tailings, minimize chemical and reagent usage and reduce environmental impact.

The ore-processing plant will be located adjacent to the Bayan Khundii open pit and throughput will target 650,000 ore-tonnes per year, nominally 1,935 tonnes per day. Total mineralized material from BK, processed in the plant over the course of the mine life, is 4.0 million tonnes at an average diluted head grade of 4.0 g/t gold. Using an estimated mill recovery of 92.6%, total recovered gold over the life of the Bayan Khundii Project is 476,000 ounces.

Operating Costs

Operating costs are based on the mining and processing scenarios outlined above and assume owner mining. Power for operations will be generated through an on-site hybrid diesel and solar generation solution, provided under a power purchase agreement for the duration of the Project. All other activities are assumed to be owner-operated. The AISC for Bayan Khundii is estimated at $869/oz.

Note: Rounding may cause computational discrepancies

Capital Costs

Construction costs, primarily comprising the process plant and supporting infrastructure, accommodation village, and associated engineering and indirect costs are estimated at US$88 million. Pre-production costs, including first fills and mobile site equipment total $2 million. Additionally, a 12% contingency, or US$10 million, has been provided in arriving at the total estimated capital cost. Sustaining capital of US$4 million has been included in the mine plan and net mine closure costs are estimated at US$7 million, accounting for salvage values. Total life of mine capital expenditures for the Bayan Khundii Gold Project are estimated at US$109 million. Approximately $5 million of costs have been incurred to date, representing deposits on long-lead mechanical equipment, temporary construction facilities and civil works.
