. Kiniero Project

Once in operations, the Kiniero project will be the flagship asset of Robex.

Kiniero was acquired by Robex in April 2022 as part of the business combination with Sycamore Mining Limited (please refer to the press release dated 9 November 2022).

The Kiniero Gold Project is a 470km² package of mining licences in the prolific Siguiri Basin, Guinea; and consists of the adjacent Kiniero (mining) and Mansounia (exploration) licences which host numerous deposits.

Construction already started, in Q4 2022

Robex is expected to restart the mine with a new CIL Processing Plant.

The NI-43101 Feasibility Study delivered in June 2023, with an Updated Feasibility Study expected to be released in September 2024

. Project Overview

The Kiniero gold mine operated from 2002 to 2014 from 2002 to 2014 and produced a total of 418,000 ounces of gold during this period.

The mine was placed on care and maintenance in early 2014 and was awarded to Sycamore in 2019.

Sycamore has invested $25 million in the project to drill the property to a definitive feasibility level for restarting the operation. Through a business combination, Robex took over the project in 2022, and now plans to restart the mine with a new processing plant. The existing mining infrastructure will be refurbished and expanded with minimal additional infrastructure required.

Robex has also commenced an extensive drilling program on the numerous deposits identified to increase the resource base and extend the mine life at Kiniero primarily by increasing drilling density at depth and along the known lateral extensions. Following completion of the first phase of Mineral Resource delineation drilling at the Mansounia deposit and recent drill spacing study, Robex reported a significant increase by 52% in its inferred resources base in December 2023 (Mineral Resource Estimate). Mansounia adds 896koz of inferred.

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.
