ASX-listed Resolute Mining, the Africa-focused gold miner, has announced an updated Mineral Resource Estimate (MRE) for the Doropo Gold Project which is situated in Northern Côte d’Ivoire.
Since acquiring Doropo in Q2 2025, Resolute has been updating the existing Definitive Feasibility Study (DFS) that was produced by Centamin in July 2024. As part of the update optimisations of the Resource have been completed at a gold price assumption of $3000/oz versus $2,000/oz in the previous 2023 MRE.
The Updated Mineral Resource Estimate of 4.4 Moz represents a substantial c. 1 Moz increase from the previous MRE of 3.4 Moz with 84% of contained ounces in the Measured and Indicated resource category. The Company is confident of further growth of the Mineral Resources as current optimisations are based on conservative pit shell assumptions and the two largest prospects, Kilosegui and Souwa that contain approximately 2.3Moz of the MRE, remain open along strike and at depth.
Resolute anticipates that, based on the plant capacity outlined in the 2024 DFS, the increase in Mineral Resources will extend the mine life by at least five years beyond the original 10-year plan. The conversion of Measured and Indicated Resources to Reserves was approximately 61% in the 2024 DFS.
Resolute is in the process of optimising pit designs and incorporating revised capital and operating cost estimates to update the Ore Reserves of Doropo. This is being done at a gold price assumption of $1,950/oz (versus $1,450/oz in the 2024 DFS). The updated DFS is expected to maintain a production profile, similar to the 2024 DFS, of more than 200koz per year in the first four years of production. All workstreams for Doropo are on track.
The updated DFS, being run by Lycopodium, is targeted for Q4 2025 along with an updated Ore Reserve. Resolute is awaiting approval of the Exploitation Permit by the Interministerial Commission followed by signing of the Presidential Decree. Following this, FID is expected by end of 2025.
Chris Eger, CEO commented: “This increase in the size of the Mineral Resource at Doropo is a promising first step and one we expected given the change in the gold environment since Centamin’s DFS published in July 2024. We are confident that Doropo will be a high-quality long-life mine underpinned by the expectation of further resource growth at Kilosegui and Souwa. The major increase over the existing Resource indicates major upside at Doropo and is a key consideration in the updated DFS. We are continuing the optimisation studies and expect to provide the updated DFS and Ore Reserve by the end of the year.”
Doropo Resolute announced the acquisition of the Doropo Gold Project on 1 May 2025. Doropo is a development stage project that is expected to increase Group production above 500koz per year once in production from 2028. The project is expected to grow and diversify Resolute’s operations in the broader West African region.
In the 2024 DFS a gold price assumption of $2,000/oz for the pit constrained RPEEE Mineral Resources and $1,450/oz for the Ore Reserves was used. Resolute is currently carrying out a number of workstreams to update the 2024 DFS which will reflect the higher gold price and revised input costs. Resolute has recently rerun new pit optimisations on all the Doropo Mineral Resource Block Models for pit optimisation using a range of gold prices. The Mineral Resource for Doropo is reported within a $3,000/oz pit shell and above a cut-off of 0.3g/t
