On 24 March 2022, MMG’s board approved the development of the Kinsevere Expansion Project.
The project will extend the life of the Kinsevere operation for at least 13 years from 2022. Construction of the Kinsevere Expansion Project (KEP), including the transition to the mining and processing of sulphide ores and the commencement of cobalt production, is progressing. All civil work for the cobalt plant has been completed, long-lead time equipment is being shipped to the site and the installation of equipment has commenced. Detailed engineering for the concentrator and roaster plant is in progress. Earthworks of the new tailing dam have started.
The first cobalt production is expected in 2023 and the first copper from the sulphide plant in 2024. |

Summary:
The Kinsevere deposit is a sediment hosted copper deposit with low-grade cobalt association.
The deposit is comprised of the R1, R2 and R3 subgroups of the Neoproterozoic Roan Group. Copper mineralisation is generally confined to the Mines (R2) subgroup, however, minor copper-oxide and copper-sulphide development occurs along the R1-R2 contact and the R2-R3 contact.
The deposit is located along a major structural element termed the Kinsevere lineament. Halokenetic and tectonic processes have resulted in the emplacement of discrete lower Roan (R2) stratigraphic blocks onto younger, upper Roan (R3 and above) stratigraphy.
The Kinsevere deposit is comprised of three distinct mineralisation domains: Central, Mashi and Kinsevere Hill. Central and Mashi form a contiguous sequence of mineralised Mine Series correlates that host copper-cobalt oxides and sulphides. Kinsevere Hill represents a structurally isolated occurrence of Mine Series host rocks containing copper-cobalt oxides with minor copper sulphides.
Copper oxide mineralisation is defined as material that has CuAS:CuT ratio between 0.5 to 1. The principal copper oxide mineral is malachite with subordinate chrysocolla, copper clays (Goethite and Mn-WAD), pseudomalachite and rare azurite. Tenorite, native copper and other minor copper oxide phases (Cuintergrows) are also present in minor quantities (~<5% of total Cu oxide mineralogy). The largest proportion of copper oxide mineralisa ........

Summary:
Mining of the Kinsevere deposits is undertaken by the open pit method, which is expected to continue throughout the life of mine.
Kinsevere mine is an open pit operation that is mining and processing oxide copper ore. The operation uses a contract mining fleet of excavators and both rigid body and articulated dump trucks along with a fleet of ancillary equipment.
This mining method is appropriate for the style and size of the mineralisation.
Minimum mining width (bench size) is typically in excess of 45m but is ~35m in some isolated areas during stage development.
All required infrastructure is in place for processing Oxide Copper bearing minerals only. Infrastructure required for the Sulphide plant is outlined in the Kinsevere Expansion Project (KEP) study. Mining rates are planned to stay relatively constant and is within the capacity of the proposed mining contractor capability and capacity.

Reserves at June 30, 2022:
Mineral Reserves cut-off grade approximates 1.1% Cu for Oxide and Transitional ex-pit material, 1.0% Cu for Primary Material and 0.9% Cu for Oxide existing stockpile reclaim.
The reporting cut-off grade applied to the model is 0.5% acid soluble copper (CuAS%) for the oxide Mineral Resource, 0.6% total copper (Cu%) for the transitional mixed (TMO) Mineral Resource and 0.6% total copper (Cu%) for the primary sulphide Mineral Resource.
