SnapshotMako is a high quality, open pit mine with attractive scale and potential life extension through several near-mine exploration opportunities.

At Mako, in 2023, Resolute successfully completed a pit cut back, exposing high grade areas that will be mined over the next two years. Key focus for 2024 is progress a Tomboronkoto near-mine satellite resource to extend the Mako mine beyond 2026.

Summary:

The Mako Mine is situated in eastern Senegal within the prolific Birimian age “Kenieba Window” geological complex that hosts multiple world class gold mining operations in eastern Senegal and western Mali.

Gold mineralisation is hosted mainly within the Felsic Unit which is sandwiched between two basalt sheets and is associated with disseminated and veinlet pyrite, quartz-carbonate-chlorite alteration and veining and is typified by zones of bleaching and hydrothermal brecciation within both the felsic unit and part of the Lower Basalt Unit.

Mineralisation is contained within a kilometre of strike length and over true widths varying between 5 and 40 metres. Mineralisation remains open at depth and previous deep drill holes have already identified higher grade shoots beneath the base of the open pit which are subject to further exploration to more fully assess their potential to support underground mining operations.

It is interpreted that the northeast striking structure controlled the flow of the gold bearing hydrothermal fluids, with the preferential chemistry/rheology of the felsic volcanic horizon acting as a favourable horizon for silicification and the deposition of the gold-pyrite mineral assemblage. Intensity of gold mineralisation appears to correlate with the intensity of pyrite development and exhibits good lateral and vertical continuity through the mineralised zone.

Mineralisation has a relatively simple geometry comprising a zone that varies from 30 to 60m in width, along the 1,700m strike length drilled to date. The zone dips approximately 20-30° to the northwest near surface, steepening to approximately 45° dip at depth.

Tomboronkoto satellite deposit
Mineral Resources at Mako decreased in line with mining depletion. Moreover, there is an additional Resources from the Tomboronkoto deposit.

Mineralisation is interpreted to be within a shear in the granodiorite unit. Intensity of gold mineralisation appears to correlate with the intensity of pyrite development and exhibits good lateral and vertical continuity through the mineralised zone.

Mineralisation has a relatively simple geometry comprising a zone that varies from 30 to 60m in width, along the 1,700m strike length drilled to date. The zone dips approximately 70° to the south southeast.
