Robex Resources Inc. 10 mins read

QUEBEC CITY, Dec. 22, 2023 (GLOBE NEWSWIRE) -- Robex Resources Inc. (TSXV: RBX) (“Robex” or the “Company”) is pleased to announce (i) a 43-101 Mineral Resources Estimate Update for the Mansounia deposit and start of an optimized Feasibility Study (“FS”) for Q2 2024, (ii) to prioritize workstreams to bring Mansounia in the Kiniero project and review the impact on the project timeline; and (iii) extension of the existing US$ 35m Bridge Facility (the “Bridge”) with Taurus Mining Finance Fund No. 2, L.P. (“Taurus”) alongside their support for the US$ 115m Project Finance Facility (the “Project Finance”).

Highlights of the Mansounia 2023 Mineral Resources Estimate (“MRE”) update include:

  • The total contained gold for Mansounia Inferred Mineral Resources on a standalone basis has increased by +169% compared to the previous 2022 Kiniero Gold Project Feasibility Study MRE on Mansounia.
  • The 2023 MRE update for Mansounia increases the total contained gold of the Kiniero Gold Project Inferred Mineral Resources by +52% compared to the previous 2022 Kiniero Gold Project FS MRE.

MANSOUNIA DEPOSIT RESOURCES INCREASES CONFIRMS PROSPECTIVITY OF THE KINIERO PROJECT

Following completion of the first phase of Mineral Resource delineation drilling at the Mansounia deposit1 and recent drill spacing study, Robex reports a significant increase in its inferred resources base, as shown in the table below. The Mansounia Central deposit is approximately 3km south of the Kiniero processing plant at the Kiniero Gold Project in Guinea, West Africa.

The Mineral Resource Estimate (MRE) update, prepared by Micon International Co Limited (“Micon”), includes the Mansounia Central and Mansounia South deposits, and has been updated based on an extensive 147 RC drill hole delineation drilling programme totalling 23,310 meters, with a complete review and remodelling of the wireframe interpretations.

MansouniaInferred29.220.95896

Notes:

  1. The Mineral Resource Estimate has been prepared in accordance with National Instrument 43-101 (NI 43-101) Standards of Disclosure for Mineral Projects and has an effective date of December 21, 2023.
  2. To demonstrate Reasonable Prospects for Eventual Economic Extraction (RPEEE), open pit Mineral Resources were constrained by an optimised pit shell. All blocks above the cut-off and within the pit shell were included in the Mineral Resources. Robex created the optimised pit shell.
  3. Cut-off grades for Mineral Resource reporting were calculated using a gold price of US$1,950 oz and are: laterite 0.5 g/t Au; saprolite (oxide) 0.3 g/t Au; saprock (transition) 0.7 g/t Au; and fresh 0.9 g/t Au.
  4. Mineral Resources are not Mineral Reserves and have not demonstrated economic viability. There is no certainty that all or any part of the estimated Mineral Resources will be converted into Mineral Reserves.
  5. Average density values used are: laterite 2.12 t/m3; saprolite (oxide) 1.66 t/m3; saprock (transition) 2.46 t/m3; and fresh 2.66 t/m3.
  6. Grade interpolation by ordinary kriging using a rotated block model (azimuth 40°) with a block size of 12 m (X) by 24 m (Y) by 5 m (Z). Outlier management used grade capping for extreme outliers and a restricted search neighbourhood for outliers on a domain-by-domain basis.
  7. All Mineral Resources were classified as Inferred. To limit extrapolation, a volume was used to constrain the interpolated blocks to approximately 10 m below the base of the drilling and 40 m lateral to the drilling.
  8. Totals presented in this table are reported from the Mineral Resource models, are subject to rounding, and may not sum exactly.

Notes:

  1. Micon completed the 2023 MRE update for Mansounia in December 2023. The total in situ Inferred Mineral Resources were calculated using the 2023 MRE Update for Mansounia.
  2. All other pits other than Mansounia were not updated in 2023 by Micon and remain unchanged from the 2022 FS as stated in the technical report by AMC Consultants “Technical Report, Kiniero Gold Project, Guinea. Effective date 01 June 2023”.
  3. The 2022 FS refers to Mansounia as Mansounia Central.

START AN OPTIMISED FEASIBILITY STUDY FOR Q2 2024

Robex has engaged Soutex and Wacom to engineer the required small design modifications, including two additional CIL tanks and a larger oxygen plant for a throughput increase to 4.1 Mtpa.

Robex is now starting working on an optimized Feasibility Study to (i) include the Mansounia resources modelling across the deposits and update the Reserves and Resources on the entire project; (ii) update the capital expenditure to accommodate a higher oxide mix at 4.1Mtpa; and (iii) add flexibility in the current design to accommodate future expansion of 6Mtpa.

CONSTRUCTION UPDATE – SLOW DOWN DUE TO FUEL SUPPLY RISK AND ENGINEERING

At this stage the impact on the project timeline is under review due to the new engineering work required and the current situation in Guinea with the fuel supply disruption which are slowing down construction activities. A revised project timeline will be communicated during H1 2024.

Current spending on the project stands at c. US$ 50m as of October 30th, 2023, and earthworks on site is progressing well (Figure 3, 4 and 5). The dewatering is also progressing well with 9 meters drop from original topography. This will give Robex access to continue delineating the resources at SGA (479Koz of inferred resources at 1.54g/t).

TAURUS BRIDGE EXTENSION UNTIL JUNE 21ST 2024

The current Bridge Facility provided by Taurus was drawn from time to time since closing of the facility in April 20232 and is now fully drawn at US$ 35m. Proceeds of the funds were allocated to developing the Kiniero Gold project by ordering of long lead items, start of earthworks and others work programs.

Given the resources update at Mansounia Central and ongoing technical works to carry out as part of the optimized Feasibility Study, Robex and Taurus agreed to extend the maturity of the Bridge Facility by 6 months from December 22nd 2023 to June 21st 2024. This additional time will allow Robex to optimize value of the Kiniero Gold project and will provide additional time to finalize the US$ 115m Project Finance Facility as set out in the Mandate Letter previously signed3. The extension comes alongside the following revised key terms:

  • Interest rate 10% per annum (from 8% currently);
  • Royalty of 0.25% capped at 1.5Moz of gold across Kiniero’s licences, including buy-back mechanism subject to specifics conditions;
  • Permitted indebtedness headroom increased from US$ 4m to US$ 12m subject to certain conditions;
  • Security, covenants and other conditions remain unchanged;

The Bridge still has no requirements for hedging. Closing of the extension is subject to customary conditions.

Aurelien Bonneviot, President and CEO: “We are pleased to see Mansounia delivering inferred resources increase. This is a significant advancement towards the delineation of the 4.5 km Sabali – Mansounia corridor. This resource confirms the prospectivity of our Mansounia Licence and that’s why the company have decided to include it in an optimised feasibility study. We thank Taurus for supporting Robex in extending the maturity of the bridge and reiterating their support for the Project Financing.”
