The Technical Report titled “Independent Technical Report for Kombat’s Asis West Mine, Namibia” is dated March 15, 2024 with an effective date of February 29, 2024, and supports the disclosure made by the Company in its press release dated March 4, 2024 announcing the positive feasibility study for its Kombat Asis West underground mine and updated mineral resources and reserves estimates. There are minor changes to the Pb grades published in the Mineral Resource tables in the March 4, 2024 press release.

The Technical Report can be found under the Company’s profile on SEDAR+ (www.sedarplus.ca) and on the Company's website (www.trigonmetals.com).

Mineral Resources and Mineral Reserve Estimates

Mineral Resources

The Mineral Resource estimate presented represents the third Mineral Resource estimate prepared for the Kombat Mine project in accordance with NI 43-101 by Minxcon (Pty) Ltd (an independent consulting company) commissioned by Trigon to undertake this work. The Mineral Resources have been independently reviewed by SRK and reported using updated techno-economic factors.

Mineral Resource estimates are shown in Tables 1 to 3 below. Mineral Resources are reported inclusive of any Mineral Reserves that may be derived from them.

Notes:

1. 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
2. The Mineral Resources have been depleted with historical mining pit shells and underground voids
3. The Mineral Resources are reported within an optimised pit shell, based on the techno-economic factors disclosed above
4. The Kombat Mineral Resources are reported above a 0.53% Cu cut-off, and the Gross Otavi Mineral Resources above a 0.60% CuEq cut-off
5. Mineral Resources are reported as total Mineral Resources and not attributable to Trigon
6. Mineral Resources are reported inclusive of any Mineral Reserves that may be derived from them
7. 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%

Notes:

1. 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
2. The Mineral Resources have been depleted with historical mining underground voids
3. The Mineral Resources are reported above a 1.2% CuEq cut-off
4. Mineral Resources are reported as total Mineral Resources and not attributable to Trigon
5. Mineral Resources are reported inclusive of any Mineral Reserves that may be derived from them
6. No geological losses are applied

Notes:

1. 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
2. The Mineral Resources have been depleted with historical mining underground voids
3. 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
4. Mineral Resources are reported as total Mineral Resources and not attributable to Trigon
5. Mineral Resources are reported inclusive of any Mineral Reserves that may be derived from them
6. 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:

1. The Mineral Reserves have been depleted with historical mining pit shells and underground voids.
2. The Mineral Reserves are reported within pit designs and scheduled.
3. The Kombat Mineral Reserves are reported above a 0.56% Cu cut off.
4. Mineral Reserves are reported as total Mineral Reserves and not attributable to Trigon.
5. 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:

1. Applied a dilution factor 0.5 m envelope of ore below cut-off in the stopes.
2. Applied an overbreak of 5% in waste development.
3. Lashing or mucking loss of blasted material in the stopes at 2%.
4. Applied a cut-off of 1.5% Cu ore.
5. The Mineral Reserve estimates are declared at the shaft head.
6. Cu metallurgical recovery applied is 93%.

The combined Mineral Reserves estimates for the Kombat mine are set out in Table 6 below.
