Notes:
- A Mineral Resource is not a Mineral Reserve, and there is no guarantee that all or part of the Mineral Resource will be converted to a Mineral Reserve
-
The Mineral Resources have been depleted with historical mining underground voids - The underground Mineral Resources are reported above a 1.2% CuEq cut-off. The Kombat open Pit Mineral Resources (All indicated) are reported above a 0.53% Cu cut-off, and the Gross Otavi open Pit Mineral Resources (All Inferred) above a 0.60% CuEq cut-off
- Mineral Resources are reported as total Mineral Resources and not attributable to Trigon
- Mineral Resources are reported inclusive of any Mineral Reserves that may be derived from them
- No geological losses are applied at Kombat. The Gross Otavi Mineral Resources include geological losses of 15%, depletion for unknown historical development of 1% and reduced by a porosity factor by 7.5%
Mineral Reserves
The open pit Mineral Reserves estimates as set out in Table 4 are limited to the Ore Capping open pits, which are situated in the Kombat East and Central areas. The LoM pit has been excluded due to interference with current underground infrastructure. The open pit Mineral Reserve estimate is declared at the RoM stockpile as a reference point.

Notes:
- The Mineral Reserves have been depleted with historical mining pit shells and underground voids.
- The Mineral Reserves are reported within pit designs and scheduled.
- The Kombat Mineral Reserves are reported above a 0.56% Cu cut off.
- Mineral Reserves are reported as total Mineral Reserves and not attributable to Trigon.
- The Mineral Reserve statement excludes 13.0 kt at 0.83% Cu sitting in stockpile.
The Mineral Reserves estimates for the underground mining schedule are set out in Table 5 below. The Mineral Reserves are reported at the point where the ore is fed into the processing plant. The Indicated Mineral Resources at No 3 shaft below the ore capping pit were not considered to be converted to Mineral Reserves at the time of the study. This was mainly due to higher Pb levels which were not considered to be marketable at the time and will be included in future study work.

Notes:
- Applied a dilution factor 0.5 m envelope of ore below cut-off in the stopes.
- Applied an overbreak of 5% in waste development.
- Lashing or mucking loss of blasted material in the stopes at 2%.
- Applied a cut-off of 1.5% Cu ore.
- The Mineral Reserve estimates are declared at the shaft head.
- Cu metallurgical recovery applied is 93%.
The combined Mineral Reserves estimates for the Kombat mine are set out in Table 6 below.
