Gemfields Group Limited release a Maiden Inferred Mineral Resource Estimate for Target Area 5 ("TL5") and an Independent Technical Report ("ITR") on the 2022/2023 Exploration Programme at its gold exploration project in Cabo Delgado, northern Mozambique. The project is housed within Nairoto Resources Limitada ("Nairoto") which is 75% owned by Gemfields and the analysis was conducted by SRK Exploration Limited ("SRK EX") with the Inferred Mineral Estimate declared in line with the JORC Code (2012). Nairoto - Maiden Inferred Mineral Resource Estimate results (TL5 Prospect Area): 1.58 million tonnes of mineralised rock with a gold grade of 2.02 gram per tonne ("g/t") based on a `Low Scenario' basis, resulting in 103 thousand ounces ("koz") of gold, The Mineral Resource is primary mineralisation, and not part of the soil horizon, and requires professional mining and metallurgical processing rather than an artisanal or `dig and pan' approach for the recovery of gold, Inferred Mineral Estimate relates only to the TL5 Prospect Area, covering less than 0.1 square kilometres of the full 1,957 square kilometre licence area, Results are based on 20 Reverse Circulation ("RC") drillholes totaling 1,464 metres.

SRK EX have identified 18 priority target locations, covering a 115 square kilometre area, based on the results of extensive regional soil sampling in conjunction with available geological and geophysical information. Nairoto intends to prioritise exploration in these target areas. Nairoto is a joint venture between Gemfields (75%) and Mwiriti Lda (25%), the Group's existing partner in Montepuez Ruby Mine ("MRM").

Nairoto became fully functional in January 2020. Nairoto is the beneficial owner of 12 licences located about 30 kilometres to the north of the MRM concession, covering an area of 1,957 square kilometres. The licences hold exploration potential for gold (both primary and secondary) as well as ruby and allied minerals through a blend of prospecting and mining licences.

Nairoto requested SRK EX to undertake a review of its 2022/2023 exploration programme and advise on the Mineral Assets of the 12 licences. SKR EX was also requested to review the geological and exploration data for TL5 Prospect on Mining Concession 9783C and which has resulted in the declaration of a maiden Inferred Mineral Resource Estimate. Mining Concession 9783C has a current expiry date of June 2044.
