Update on Construction Activities
Construction of the project started in Q4 2022, with US$ 27m expected to be spent by June 30, 2023 of the initial capital costs of US$ 160m (or 17% of total):
- Contractors mobilized on site and detailed engineering is ongoing;
- In line with the previously disclosed mandate with Taurus Mining Finance Fund No. 2, L.P. (“Taurus”), we are currently discussing the terms of the Project Finance Facility and providing information needed for due diligence. Please see the press releases dated January 24, 2023 and March 21, 2023 available on SEDAR at www.sedar.com for further details;
- Resource expansion program ongoing, the last drill hole in the geological database supporting the FS dates from August, 17, 2022 with 24,443m of drilling completed since then; and
- Exploration is underway at our Mankan target in the north portion of the property for the first time since the project was owned by SEMAFO.
Aurélien Bonneviot, CEO of Robex commented: “The completion of the FS for the Kiniero Gold Project is a major milestone in our journey towards project development, as the FS optimizations and updated Mineral Resource Estimate result in a stronger project with enhanced economics.
Since the announcement of the Kiniero acquisition on 20 April 2022, we have improved the asset to reach a now-projected 9.5-year LoM. Kiniero is now expected to average above 100koz per annum over the first 7 years and we will continue to drill to hopefully increase the average grade, the production capacity and the LoM.
This FS incorporates the actual pricing and tenders we have been collecting for the construction, giving us confidence in the upfront capex estimates. The majority of the parameters are at the detailed design stage, the construction crew has mobilized on site, and we are on track for the first gold poured in mid-2024.
While the FS includes a 21% increase in Mineral Reserves, this represents only a fraction of the total Mineral Resource, and we are targeting additional conversions of Mineral Resources to Mineral Reserves in the coming years. With more than 1moz of Inferred Mineral Resources within 10 km of the processing plant, we see potential for significant LoM extensions and rapid growth at the asset in a short timeframe.
With these excellent results, Robex will focus its efforts on the previously announced debt package with Taurus Mining Finance Fund No. 2, L.P.”.
Feasibility Study Highlights
The ore mined from the Kiniero deposit is expected to be processed through a standard 3.0mt capacity Carbon-in Leach/Gravity (“CIL”) plant. The mine is expected to be an open pit using conventional mining methods.

As shown in Figure 1: Gold Production and AISC Summary across the LoM below, the Study demonstrates Kiniero’s ability to deliver an average of 90koz of gold per year at an AISC of US$ 980/oz over the LoM, as mine plan optimization efforts prioritized a stable, long mine life, rather than peak upfront production. Over the coming years, Robex intends to continue its exploration efforts to continue to extend the LoM and increase annual production.

FEASIBILITY STUDY DETAILS
The Project is located in eastern Guinea in the Kouroussa Prefecture. It is situated approximately 27km southeast of the town of Kouroussa and at a distance of 546km from Conakry, the capital of Guinea (Figure 2: Regional Locality of the Kiniero Gold Project and Regional Infrastructure of Guinea).
The Kiniero Gold Project is a 470.48km² exploitation and exploration land package that consists of the adjoining Kiniero exploitation License Area and Mansounia exploitation License Area. The Kiniero Project is one of the largest gold licences in Guinea.
Figure 2: Regional Locality of the Kiniero Gold Project and Regional Infrastructure of Guinea
Kiniero gold deposits, located in the prolific gold-producing Siguiri Basin, were discovered in the early 1900s and were subsequently explored until 2002 when gold production began under the ownership of Semafo Inc and its subsidiary Semafo Guinée SA.
The historical Kiniero gold mine comprised an open pit mining operation that produced 418,000 ounces of gold during its 12-year operational history. The mine was placed on care and maintenance in early 2014.
Robex is now restarting the Kiniero gold mine as a long-life open pit mining operation based on constructing a new 3Mtpa process plant.
Given the strong exploration potential, a combination of near plant brownfields infill and known extension, as well as greenfield large-scale targets, Robex is targeting (i) the discovery of Mineral Resources across the Kiniero exploration permit area over the next few years, and (ii) the conversion of Mineral Resources into Mineral Reserves.
An extensive drilling programme is ongoing on the numerous identified deposits to increase the resource base and extend the LoM at Kiniero predominately through extending the drilling density at depth and along known strike extensions.
Since the beginning of the construction, Robex has been committed to involve village communities in the mine’s development, as well as exploring sustainable power energy source to reduce and limit its environmental footprint.
The property is located within the Kiniero Gold District of the Siguiri Basin, which is situated in north-eastern Guinea, extending into central Mali. Geologically, the Siguiri Basin comprises a portion of the West Africa Birimian Greenstone Belt, including intrusive volcanics (ultramafics to intermediate) and sediments largely deposited through the period 2.13 Ga to 2.07 Ga.
The volcanic and sedimentary lithologies comprise fine-grained sedimentary rocks (shales and siltstones), with some intercalated volcanic rocks. Sandstone-greywacke tectonic corridors have been preferentially altered and locally silicified, supporting extensive brittle fracture networks. These in turn have provided host environments for ascending mineralized hydrothermal fluids.
The deposits located on the property are associated with the Proterozoic Birimian orogeny of West Africa. Most gold mineralization in the West African Craton is shear-zone-hosted and structurally controlled, with lithology having a minor, local influence. The mineralization developed in the Kiniero Gold District conforms to this general style of mineralization.
A total of 47 gold anomalies have been identified on the property, of which five clusters of deposits (Sabali, Mansounia, SGA, Jean, and Balan) have been explored sufficiently to enable the estimation of Mineral Resources.
Figure 3: Location of the main Kiniero deposits and cross sections (A-B, C-D) and Figure 4: Cross sections through the SGA (A-B) and Sabali South (C-D) deposits illustrate the location of the main Kiniero deposits and cross sections through the SGA and Sabali South deposits. The selected cross sections display the 0.3g/t gold grade shell, Pit and RPEEE (Reasonable Prospects for Eventual Economic Extraction) Shells, significant gold intercepts (minimum of 2m @ 0.5g/t), and regolith profiles across each deposit. Section A-B, across SGA, demonstrates the deposit’s significant northeast strike and depth extension. Section C-D, across Sabali South, shows the deposit’s deep weathering saprolite and saprock profile in the east (beyond 100m in areas).

The Kiniero Project’s 2023 planned exploration programme includes a combination of brown and greenfields exploration activities. Greenfields activities comprise the continuation of the license-wide soil geochemistry (BLEG) programme, focussed on completing the Northern Block area of the Kiniero License. In addition, a maiden RC drilling campaign in the Northern Block is planned to target the Mankan, Heriko and “Filon Bleu” deposits. The drilling will build on the exploration data already generated by SMG and historical drilling completed by Semafo to further delineate the deposits.
Brownfields exploration will consist of trenching and drilling at and around the near-mine deposits. Drilling will be a combination of diamond and RC drilling and the purpose is twofold, namely Resource addition and Resource to Reserve conversion. Drilling will focus on four deposits: SGA, NEGD, Sabali South and Mansounia Central. SGA, NEGD and Sabali South will comprise Resource addition drilling by strike and depth extension, as well as Reserve conversion drilling. A grid drilling programme at Mansounia Central is designed to further delineate and upgrade the Resource.
A planned total of approximately 5,000m of diamond and 65,000m of RC drilling will be completed at the various deposits. However, the drilling programme will be an iterative process based on the ongoing results and the impact thereof. As a result, the plan may be changed and adapted to any changes in strategy.
Mining at Kiniero is expected to be undertaken by conventional contractor-operated truck and excavator open-pit mining in the SGA, Jean, SGD, Sabali South, and Sabali North and Central pits using Komatsu PC1250-sized excavators mining on 5 m benches and 2.5 m flitches loading 55 t Volvo A60H haul trucks.
Mining in upper oxide layers will be free-dig with drill-and-blast required in areas that mine through the transitional material into fresh rock. The free-dig nature of the oxide and transitional zones has been confirmed by extensive previous mining at the site. Drill-and-blast will be required for approximately 1% of the oxide material, 40% of the laterite, 60% of the transitional, and 100% of the fresh.
Ore will be categorized by material and grade through in-pit grade control and will be hauled to the mine ore pad (MOP). Waste will be hauled to the nearest available waste dump by the Volvo A60H fleet.
Historic mining in Jean, SGA, and SGD has resulted in pit lakes that require dewatering and clean-up before mining.
The key mining infrastructure including pits, waste dumps, stockpiles, and haulage roads is shown in Figure 5: Key Mining Infrastructure Layout.
Figure 5: Key Mining Infrastructure Layout
Soutex Inc. (“Soutex”) was commissioned by Robex to undertake the detailed design of the new processing plant. The process plant design is based on a metallurgical flowsheet developed for flexible operation between the various types of ore while maintaining the throughput and gold recovery. Ore will be processed on-site, at a centrally located processing facility near the mining areas. The gold will be recovered in a beneficiation plant that has been designed to process a blend of oxide, laterite, transition, and fresh ores from various ore deposits.
Oxide and upper transition ores (soft) require less comminution energy than laterite and fresh ore (hard). However, they present other challenges in handling due to the sticky nature of oxide ore types, justifying dedicated crushing devices for soft and hard ores. The process plant design has been based on a nominal capacity of 3.0 Mtpa. The flowsheet includes crushing, semi-autogenous grinding (SAG) milling, gravity concentration, thickening, CIL leaching, Zadra elution, gold electrowinning, and carbon regeneration and SO2 detoxification, which are well-proven in the industry.
Figure 6: 3D Processing Plant
The Project benefits from good infrastructure in close proximity to the site, and a limited relocation requirement as there are no villages on the site. Existing mining infrastructure will be refurbished with minimal additional infrastructure required.
In addition, early works have focused on advancing the site infrastructure to facilitate a smooth transition into construction. Site roads to the mine from the national road network, mine perimeter fence, and the earthworks for the construction camp have already been completed as part of the early works, incurred during the first six months of 2023.
New infrastructure will be added to support mining, processing and waste management on the mining license including power transmission line, diesel generators, and additional site facilities and accommodation for staff.
The Project will utilize a diesel-solar and battery storage hybrid power plant consisting of diesel generators with a capacity of approximately 13,286kW, a solar photovoltaic (PV) plant with a total capacity of approximately 18,030kWp/14,400kW and the battery energy storage system with a capacity of 6MWh/12MW. Robex is part of a clear policy of reducing CO2 emissions from its operations on-site.
The hybrid power plant has been developed based on Vivo Energy providing power as an Independent Power Producer (IPP). Vivo Energy will be responsible for all energy requirements of the mine and the fuel storage capacity. The diesel generator will be the prime source of power supply. The PV battery plant will be displacing the thermal generation by up to 40% during solar hours with support from a battery energy storage system (BESS).
The PV battery and diesel generator plant will be connected directly to the main switchboard of the mine at a high voltage of 15 KV through a dedicated power line infrastructure. The distribution will supply the camp, plant, mining workshops, and the tailings storage facility (“TSF”) via the Mine’s main switchboard.
Water for operations is to be sourced from the proposed TSF (prioritized), dewatering of historical pits, and boreholes. Allowance has been made for the procurement and installation of industrial Reverse Osmosis units. Water supply to the Reverse Osmosis units will be via existing boreholes near each camp.
Process water will be primarily sourced from recirculated TSF water. It is continuously recirculated from the TSF to the process water pond and the processing plant, mainly in the milling area. A pump located in the process water feeds the process water distribution network of the mill. Raw water is added to the process water pond through the freshwater tank overflow to compensate for the process water losses. The proposed water supply is sufficient to meet the process plant requirements.
Epoch Resources (Pty) Ltd (Epoch) was commissioned by SMG to undertake the detailed design of the new TSF. The proposed TSF is required to accommodate 36 Mt of tailings over a 12 years LoM at a rate of 250 ktpm (3 Mtpa). The required storage volume for the tailings has been calculated based on an estimated average in situ dry density of the tailings product of 1.39 t/m3, a particle specific gravity (SG) of 2.77 t/m3, and an estimated average in situ void ratio of 1.
The TSF is expected to be constructed in phases as a full containment facility incorporating an HDPE liner to the basin and inside faces of the containment walls to mitigate against the potential for groundwater pollution. Management and monitoring systems is expected to be implemented to ensure that risks associated with the facility are identified and mitigated in line with accepted practices and standards.

Operating Costs Summary
Mining operating cost estimates were prepared by AMC Mining Consultants (UK) Ltd (“AMC”). Processing costs were prepared by Soutex while Infrastructure and General and Administration (“G&A”) operating cost estimates were prepared by Robex and reviewed by AMC. LoM operating unit costs are summarised in the table below.
Table 5: LoM operating unit costs
|(US$/t ore processed)||Operating costs|
|Refining and transport charges||0.1|
Capital Costs Summary
The process plant capital cost estimate was compiled by Soutex with input from Epoch on the TSF and Robex on the water infrastructure and site access roads. Robex has provided estimates for mine establishment, infrastructure facilities, high-voltage power supply and owner’s costs.
Starting January 1, 2023, the total LoM capital cost is estimated at US$ 234m, including US$ 160m of initial capex, US$ 31m of development capex post-construction period and US$ 43m of sustaining capital, as shown in table below. The initial capital costs include an 8% contingency while the capex during operations includes a 5% contingency.
Table 6: Capital Cost Estimate Summary
|Category, in US$k||Initial CapEx||Capex during operations||Sustaining Capex over LoM||Total Capital Costs LoM|
The construction has already started, and US$ 27m out of the US$ 160m (the equivalent of 17% of the total) are expected to be spent as of June 30, 2023. The first gold poured is expected in mid-2024.
The closure costs have been estimated by ABS Africa to be a total of US$ 19.9m. This includes Contractors, Preliminary and General Costs, Engineering Design and Environmental Permitting.
Environment and Social
Under the Mining Code, all applicants for an exploitation licence must submit an Environmental and Social Impact Assessment (“ESIA”). Robex completed the ESIA in the past few weeks. There are currently no objections known to Robex to the development of the Project.
The environmental permit for the Project was received and an Environmental and Social Management Plan (“ESMP”) is being implemented to guide Robex’s local community engagement as well as ensure it fulfils its environmental obligations, minimizing the mine’s impacts where possible. The ESMP will be used to ensure compliance with environmental specifications, monitoring and management measures and will be implemented from site preparation through to decommissioning and closure.
Robex believes that its most significant contribution to sustainable and responsible development is to help its local employees obtain or complete their professional qualifications, thereby ensuring long careers. Robex intends to replicate the mine-school concept in Guinea from its existing operation in Mali, targeting a >90% local talent of its skilled workforce.
During construction activities, approximately 450 employees will be onsite. During operating activities, the team will consist of 400 Robex employees (excluding exploration) and 450 contractors.
Ownership, Permitting, Taxes and Royalties
Once a mining convention is signed with the Government of Guinea, Robex will have an 85% ownership stake in Kiniero, while Soguipami (the Guinean state-owned mining company) will have a stake of 15%. Subject to the Government of Guinea’s 15% interest, Robex also has the exclusive rights to acquire full ownership of the Mansounia exploitation license pursuant to a technical partnership agreement entered into with Penta Goldfields Company S.A subject to the satisfaction of the certain conditions precedent. Robex submitted to the Government of Guinea an application to convert the licenses into exploitation. Ultimately, Robex will own 85% of Kiniero and Mansounia with the balance owned by the Guinean state. Both properties will be governed by the same mining convention.
Subject to adjustment with a mining convention the corporate tax rate of 30% of gross profit has been applied in the FS. A royalty rate of 5.5%, a 1% contribution to the Local Mining Development Fund and a 0.5% private royalty were applied to all sales.
An economic analysis has been carried out for the Project using a cash flow model. The model has been constructed using annual cash flows taking into account annual processed tonnages and grades for the CIL feed, process recoveries, metal prices, operating costs and refining charges, royalties and capital expenditures (both initial and sustaining). A payability factor of 99.95% has been assumed for purposes of gold sales.
The financial analysis used a base price of US$ 1,650/oz. The financial assessment of the Project is carried out on a “100% equity” basis and the debt and equity sources of capital funds are ignored. No provision has been made for the effects of inflation. Discounting and IRR calculations have been applied as of July 1, 2023, using a 5% discount rate. Capital costs spent until June 30, 2023, are considered sunk.
