Robex Resources Inc. 11 mins read

QUEBEC CITY, May 22, 2024 (GLOBE NEWSWIRE) -- Robex Resources Inc. (TSXV: RBX) (“Robex” or the “Company”) is pleased to announce a Mineral Resource Estimate update prepared by Micon International Co Limited (“Micon”) for the Mansounia Central and Mansounia South deposits (collectively, the “Mansounia Deposit”) in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”), (the “Mansounia 2024 MRE Update”).

Highlights of the Mansounia 2024 MRE Update include:

  • The total contained gold for the Mansounia Indicated Mineral Resources is reported as 303koz following the conversion of 35% of Inferred Mineral Resources to Indicated Mineral Resources compared to the previously announced Mansounia 2023 MRE update1; and
  • The Mansounia 2024 MRE update increases the total in-situ contained gold of the Kiniero Gold Project Indicated Mineral Resources by 23% compared to the previous 2023 Kiniero Gold Project Feasibility Study MRE.

Aurelien Bonneviot, Chief Executive Officer commented: “I am very encouraged by the results of the Mansounia infill drilling program. They have confirmed the geological potential of the 5km mineralisation trend from Sabali North to Mansounia South and our ability to convert Inferred Mineral Resources to Indicated Mineral Resources.”

Mansounia Deposit Indicated Mineral Resources reinforce prospectivity of the Kiniero Project

Following completion of the first phase of infill drilling at the Mansounia Deposit, Robex reports a significant conversion of Inferred Mineral Resources to Indicated Mineral Resources, resulting in an increase of the in-situ Kiniero Gold Project Indicated Mineral Resources. The results are shown in the tables below. The high conversion rate supports the geological interpretation and mineralisation model for the Mansounia Deposit.

The Mansounia 2024 MRE Update prepared by Micon includes the Mansounia Central and Mansounia South deposits, and has been prepared based on a 126 Reverse Circulation (“RC”) infill drilling program on a 30m-by-30m grid totaling 11,029 meters. A single block kriging drill hole spacing study was used to inform the infill drill grid spacing and Mineral Resource classification.

Notes:

  1. The Mineral Resource Estimate has been prepared in accordance with NI 43-101 and has an effective date of May 16th, 2024.
  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. Micon 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 12 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. Mineral Resources in volumes with a drill grid spacing of 30 m by 30 m were classified as Indicated Mineral Resources based on the results of a single block kriging drill hole spacing study updated as part of the Mansounia 2024 MRE Update. All other volumes were classified as Inferred Mineral Resources. To limit extrapolation, a wireframe 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 reported from the Mineral Resource models, are subject to rounding, and may not total exactly.
  9. The Mansounia license is currently in the process of conversion from exploration to exploitation.

Notes:

  1. Micon completed the 2023 MRE update for Mansounia in December 2023. Reported Inferred Mineral Resources differ from December 22nd press release due to updated cut-off grade values being used.
