Commenting on the Company's latest progress, Len Kolff, Chief Geologist of IronRidge, said:

"The initial drilling results represent a significant milestone for the Cape Coast Lithium portfolio, with broad, continuous and high-grade lithium pegmatite intersections returned."

"Long drill intersections of 128m @ 1.21% and 111m @ 1.35% Li2O as well as very high-grade intersections up to 3m @ 3.29% Li2O is a fantastic result for a first phase drill programme; confirming Ewoyaa as a significant discovery and providing confidence for further exploration success within the portfolio."

"High grades over significant intervals and proximity to essential infrastructure coupled with the pro-mining and stable jurisdiction of Ghana bodes well for the future development of the Cape Coast Lithium portfolio."

"Results received to date indicate the development of a broad, continuous high-grade zone within the Central and Northern Extension zones which remains open to the north and potentially north-east, with additional drilling results pending."

"We will continue to advance the regional soil sampling programme and rapid analysis using our handheld LIBS lithium analyser whilst in parallel reviewing new drilling results as they are reported and commence planning for resource and exploration drilling programmes."

"I am very proud of our Ghanaian exploration team; predominantly recruited and trained from within the local community and now at the forefront of lithium exploration in Ghana."

Initial Drilling Results

Assay results have been received for the first 4,180m of drilling completed as part of the initial 8,090m RC drill programme completed at the Ewoyaa Project (refer RNS 29 May 2018). All samples were analysed by SGS Canada Inc. with check analysis completed by ALS Brisbane. Results have passed internal quality assurance and quality control ("QAQC") checks including certified standards, blanks and duplicates.

Multiple high-grade, continuous broad lithium mineralised intersections were returned at a 0.5% Li2O cut-off and maximum 10m of internal dilution (refer Figure 1 and Table 1) including highlights of:

· Hole GRC0004: 128m @ 1.21% Li2O (incl. 70m @ 1.53% Li2O from 13m (incl. 5m @ 2.57% Li2O from 38m) and 16m @ 1.36% Li2O from 115m),

· Hole GRC0027: 111m @ 1.35% Li2O from 37m (incl. 65m @ 1.58% Li2O from 40m (incl. 32m @ 1.72% Li2O from 57m) and 20m @ 1.51% Li2O from 124m (incl. 5m @ 1.94% Li2O from 131m) and

· Hole GRC0015: 35m @ 1.49% Li2O from 3m (incl. 13m @ 1.75% Li2O from 7m and 6m @ 2.35% Li2O from 26m) and

· Hole GRC0014: 15m @ 2.01% Li2O from 23m (incl. 10m @ 2.6% Li2O from 24m (incl. 3m @ 3.29% Li2O from 29m).

Very coarse spodumene crystal fragments are clearly visible in the RC drill chips for the reported intervals. This observation, coupled with the initial mineralogical characterisation study completed (refer RNS 17 January 2018), indicates spodumene is the dominant lithium mineral phase; the preferred feedstock from hard-rock pegmatite projects which bodes well for a simple process flow-sheet design.

Drill intersections received to date indicate that the Ewoyaa deposit consists of steeply east dipping to sub-vertical pegmatite dykes with interpreted true widths between 20m up to 80m where in the Central zone they appear to widen at surface on the basis of trench intersections (refer RNS 29 May 2018, Figure 2 and Figure 3).

Results received to date highlight a developing broad, continuous, high-grade lithium mineralised zone within the Central and North Extension zones, which remains open to the north and potentially to the north-east. Additionally, the pegmatite intersected within the northern-most drill section of the North Extension zone remains open to the north (refer Figure 4).

Additional targets including the Abonko pegmatites and Substation Pegmatite occur within close proximity of the Ewoyaa Project. Previous reported exploration has returned results including 25m @ 1.62% Li2O in trenching and up to 2.95% Li2O in rock chip sampling at the Abonko target (refer RNS 9 November 2017).

The Ewoyaa Project is strategically located within 1km distance of a bitumen highway, close proximity of grid power, within 100km of the Takoradi deep sea port and 100km of the capital city of Accra (refer Figure 4 and Figure 5).

The regional Laser Induced Breakdown Spectroscopy ('LIBS') and portable X-ray fluorescence, ("pXRF") soils programme is progressing steadily across the granted tenements within the Cape Coast portfolio. To date in excess of 12,460 soil samples have been collected across the granted licenses, with LIBS and pXRF analysis ongoing within our dedicated lab at the Mankessim office/residence (refer RNS 7 August 2018).

Results are still pending for the North Extension and North-East Zone where visual logging of RC drill chips indicates the presence of coarse spodumene crystal fragments within drilled pegmatite intervals.

Assay results for the remaining 3,910m of drilling will be reported as soon as they are reported by the laboratory and have passed internal QAQC review.

The Board is pleased with the progress that the Company has made to date and looks forward to keeping shareholders updated as further news becomes available.

Notes to Editors:

IronRidge Resources is an AIM-listed mineral exploration company with frontier assets in both Australia and West Africa, with two province scale projects in Gabon, and promising and advanced titanium and bauxite projects in Queensland, Australia. IronRidge's corporate strategy is to create and sustain shareholder value through the discovery of world-class and globally demanded commodities.

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.

May Queen is located in Central Queensland within IRR's wholly owned Monogorilby license package and is highly prospective for gold. Historic drilling completed during the 1980s intersected multiple high-grade gold intervals, including 2m @ 73.4 g/t Au (including 1m at 145g/t), 4m @ 38.8g/t Au (at end of hole) and 3m @ 18.9g/t Au, over an approximate 100m strike hosting numerous parallel vein systems, open to the north-west and south-east.

Wholly owned Quaggy contains highly anomalous platinum, palladium, nickel, cobalt and copper exploration targets and is located in Central Queensland, within a short trucking distance of the dormant rail system 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.

Chad

The Company entered into an agreement with Tekton Minerals Pte Ltd of Singapore concerning its portfolio covering 900km2 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. Initial trenching results at Dorothe, including 14.12g/t Au over 4m, 34.1g/t over 2m and 63.2g/t over 1m, have defined significant gold mineralised quartz veining over a confirmed 1km strike at an average of 2m and up to 5m true width, across multiple stacked vein zones over a 250m wide zone, with new hard-rock artisanal workings potentially extending strike to >3km.

Ghana

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 resource, estimated to be in the order of 1.48Mt at 1.67% Li2O and surrounding tenements. The portfolio covers some 645km2 with a further identified 20km strike of pegmatite vein swarms. Tenure package is also highly prospective for tin, tantalum, niobium and gold, which occur as accessory minerals within the pegmatites and host formations.

Côte d'Ivoire

The Company entered into conditional joint venture arrangements in Côte d'Ivoire, West Africa; securing access rights to highly prospective gold mineralised structures and pegmatite occurrences covering a combined 3,235km2 and 1,177km2 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.
