QUÉBEC CITY, June 14, 2023 (GLOBE NEWSWIRE) -- Robex Resources Inc. (“Robex” or the “Company”) (TSXV: RBX) is pleased to announce the results of the feasibility study (the “FS”, “Feasibility Study” or the “Study”) for the Kiniero Gold Project (the “Kiniero Gold Project”, or the “Project”) in Conakry, Guinea. The FS was prepared in accordance with Canadian Securities Administrators’ National Instrument 43-101 - Standards of Disclosure for Mineral Projects (“NI 43-101”).

The independent NI 43-101 technical report supporting the Kiniero Gold Project Feasibility Study will be published on SEDAR at www.sedar.com within the next 45 days.

HIGHLIGHTS:

  • Improved economics: 26% increase in pre-tax Net Present Value 5% (“NPV5%”) to US$ 251m and Internal Return Rate (“IRR”) of 42% at a base case gold price of US$ 1,650/oz while post-tax NPV5% stands at US$ 170m and IRR at 31%;

  • Increased Life of Mine (“LoM”): Mineral Reserves increased by 165koz or 21% to 968koz from the Pre-Feasibility Study (“PFS”), increasing LoM to 9.5-years (46% up compared to PFS);

  • Lower costs: LoM All-In Sustaining Costs (“AISC”) below initial target of US$ 1,000/oz, at US$ 980/oz, improving from PFS (US$ 1,035/oz);

  • Lower strip ratio: LoM Strip Ratio of 2.8:1, from 4.4:1 in the PFS; and

  • Significant potential beyond Mineral Reserve life in FS: Indicated Mineral Resources (inclusive of Mineral Reserves) at 1,481koz @ 1.07g/t, along with Inferred Mineral Resources of 1,090koz@ 1.19g/t effective November 12, 2022;

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.
