Ø New mineralised pegmatite intersections confirmed in drilling results at the Ewoyaa North target where mineralisation remains open to the north and south.

Ø Drilling ongoing; assay results reported herewith for an additional 3,081m of the current programme, designed to add resource tonnes within the immediate ELP resource area and test new exploration targets within the adjacent Saltpond license.

Ø Ideal infrastructure support: projects located within 110km of the operating Takoradi deep-sea port, within 100km of the capital Accra and adjacent to the sealed Takoradi - Accra highway and high-power transmission lines.

Ø Highly supportive government; long mining history, strong diversification drive and pro-renewable and stored energy space initiatives.

Ø Increasing lithium demand due to its role in the stored energy transition.

Commenting on the Company's latest progress, Vincent Mascolo, Chief Executive Officer of IronRidge, said:

"We are highly encouraged with the ongoing results received, which continue to confirm additional high grades in new exploration targets tested within the ELP area.

"The Board is delighted to have defined a new mineralised structure at the Ewoyaa North target, where broad pegmatite intersections, including 50m at 1.36% Li2O, have been reported, which remains open along strike and is within 210m of the currently defined resource footprint.

"We are confident the additional exploration targets will increase resource scale and improve project economics, where we have defined Ghana's first lithium JORC compliant resource of 14.5Mt at 1.31% Li2O, within 110km of an operating deep-sea port. This drilling programme is a key part of our work towards expanding the resource base on what we consider to be an industry-leading asset; we are now evaluating options to fast track the project to production.

"Earthworks are underway for the infill drill programme as well as planning for metallurgical test-work, mining and engineering studies in support of the Pre-Feasibilty Study.

"The Company is ideally positioned to take advantage of the increasing demand for lithium due to its role in the stored energy transition and looks forward to keeping shareholders up to date as further results become available."

Ongoing Drilling Results

Additional drilling results for 3,081m in 22 holes have been received for the ongoing drill programme. Multiple high-grade drill intersections have been returned, with highlights reported in Table 1 and Figure 1 at a 0.4% Li2O cut-off and maximum 4m of internal dilution (refer Appendix 1 for all reported intersections).

All sampling was completed at 1m sampling intervals at the drill site and submitted for analysis at Intertek laboratory with sample preparation completed in Ghana and sample analysis in Perth, Western Australia. All results passed internal and laboratory QA/QC protocols, providing confidence in the reported results.

The drilling programme is designed to test multiple new spodumene-bearing pegmatites identified through the Company's recent and ongoing auger drill programme; to add resource tonnes within the immediate ELP area. The programme will also advance the regional exploration pipeline by drill testing the Ndasiman, Amoanda and Hweda targets within the Saltpond and Apam West licenses respectively (refer Figure 3).

The original planned 12,500m RC drilling programme was increased to 16,500m to test strike extensions of recently drilled pegmatites where mineralisation remains open and to test new targets with drilling ongoing (refer RNS of 13 April 2021).

Notes to Editors:

IronRidge Resources is an AIM-listed, Africa focussed minerals exploration company with a lithium pegmatite discovery in Ghana, extensive grassroots gold portfolio in Côte d'Ivoire and a potential new gold province discovery in Chad. The Company holds legacy iron ore assets in Gabon and a bauxite resource in Australia. IronRidge's strategy is to create and sustain shareholder value through the discovery and development of significant and globally demanded commodities.

Côte d'Ivoire

The Company entered into conditional earn-in arrangements in Côte d'Ivoire, West Africa; securing access rights to highly prospective gold mineralised structures and pegmatite occurrences covering a combined 3,584km2 and 1,172km2 area respectively. The projects are well located within access of an extensive bitumen road network and along strike from multi-million-ounce gold projects and mines. The Company's most advanced project is the Zaranou gold project which includes high-grade gold drilling intersections along 8km strike including 6m at 6.44g/t gold from 132m, 6m at 15.11g/t gold from 26m, 4m at 5.16g/t gold from 110m and 22m at 3.39g/t gold from 8m within a broader 47km long gold anomalous structure.

Ghana

The Cape Coast Lithium portfolio covers some 684km2 and includes the newly discovered Ewoyaa Lithium Project with a maiden Mineral Resource estimate of 14.5Mt at 1.31% Li2O in the inferred and indicated category including 4.5Mt at 1.39% Li2O in the indicated category (reported in accordance with the JORC Code). The Company entered into earn-in arrangements with Obotan Minerals Limited, Merlink Resources Limited, Barari Developments Limited and Joy Transporters Limited of Ghana, West Africa, securing the first access rights to acquire the historical Egyasimanku Hill spodumene rich lithium deposit, estimated to be in the order of 1.48Mt at 1.67% Li2O and surrounding tenements. The tenure package is also prospective for tin, tantalum, niobium, caesium and gold, which occur as accessory minerals within the pegmatites and host formations.

Chad

The Company entered into an agreement with Tekton Minerals Pte Ltd of Singapore concerning its portfolio covering 746km2 of highly prospective gold and other mineral projects in Chad, Central Africa. IronRidge acquired 100% of Tekton including its projects and team to advance the Dorothe, Echbara, Am Ouchar, Nabagay and Kalaka licenses, which host multiple, large scale gold projects. Trenching results at Dorothe, including 84m at 1.66g/t Au (including 6m at 5.49g/t & 8m at 6.23g/t), 4m at 18.77g/t Au (including 2m at 36.2g/t), 32m at 2.02g/t Au (including 18m at 3.22g/t), 24m at 2.53g/t Au (including 6m at 4.1g/t (including 2m at 6.2g/t) and 2m at 6.14g/t), 14.12g/t Au over 4m, 34.1g/t over 2m and 63.2g/t over 1m, have defined significant gold mineralised quartz veining zones over a 3km by 1km area including the steep dipping 'Main Vein' and shallow dipping 'Sheeted Vein' zones.

Australia

Monogorilby is prospective for province scale titanium and bauxite, with an initial maiden resource of 54.9MT of premium DSO bauxite. Monogorilby is located in central Queensland, within a short trucking distance of the rail system leading north to the Port of Bundaberg. It is also located within close proximity of the active Queensland Rail network heading south towards the Port of Brisbane.

Gabon

Tchibanga is located in south-western Gabon, in the Nyanga Province, within 10-60km of the Atlantic coastline. This project comprises two exploration licenses, Tchibanga and Tchibanga Nord, which cover a combined area of 3,396km2 and include over 90km of prospective lithologies and the historic Mont Pele iron occurrence.

Belinga Sud is Located in the north east of Gabon in the Ogooue-Ivindo Province, approximately 400km east of the capital city of Libreville. IRR's licence lies between the main Belinga Iron Ore Deposit, believed to be one of the world's largest untapped reserves of iron ore with an estimated 1bt of iron ore at a grade >60% Fe, and the route of the Trans Gabonese railway, which currently carries manganese ore and timber from Franceville to the Port of Owendo in Libreville.
