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

"Ongoing positive drilling results including 72m @ 1.27% and 67m @ 1.21% Li(2) O as well as high-grade intersections including 38m @ 1.65% Li(2) O continues to confirm Ewoyaa as a significant discovery and provides the Company with 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."

"Essential infrastructure including roads and power, within 100km trucking distance of an operational deep-sea port and a well-trained local workforce is a significant advantage for the project with potential for a low capital and operational intensity start-up."

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

"Field teams have commenced a pitting programme to further define the Ewoyaa pegmatite footprint along the North Extension ahead of drilling programmes."

"Planning is underway for a metallurgical diamond drilling programme, which is planned to commence post receipt of the remaining 1,704m of drilling results."

"Field teams are finalising the regional soils programme across the Cape Coast Lithium Portfolio and rapid analysis using our handheld LIBS lithium analyser to define exploration targets ahead of pitting and drilling."

"The Ewoyaa Project occurs within one of nine lithium licenses the Company holds in Ghana and represents the most advanced exploration project in the portfolio."

Additional Drilling Results

Additional assay results have been received for a further 2,206m of drilling completed as part of the initial 8,090m RC drill programme completed at the Ewoyaa Project (refer to RNS on 29 May 2018 and 28 August 2018). All samples were analysed by SGS Canada Inc. 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% Li(2) O cut-off and maximum 10m of internal dilution (refer to Figure 1 and Table 1) including highlights of:

-- GRC0048: 72m @ 1.27% Li(2) O from 24m including 56m @ 1.5% Li(2) O from 28m (incl. 38m @ 1.65% Li(2) O from 36m)

-- GRC0049: 67m @ 1.21% Li(2) O from 70m including 41m @ 1.2% Li(2) 0 from 70m (incl. 5m @ 1.57% Li(2) O from 82m and 8m @ 1.4% Li(2) O from 100m), and 18m @ 1.47% Li(2) O from 114m (incl. 7m @ 1.69% Li(2) O from 114m)

-- GRC0051: 36m @ 1.04% Li(2) O from 64m including 14m @ 1.47% Li(2) O from 64m (incl. 11m @ 1.59% Li(2) 0 from 67m), and 8m @ 1.11% Li(2) O from 92m

   --     GRC0050: 20m @ 1.41% Li(2) O from 70m including 13m @ 1.51% Li(2) O from 73m 

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 to RNS on 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 to RNS on 29 May 2018 and 28 August 2018, Figure 2 and Figure 3).

Additional results received continue to confirm the developing broad, continuous, high-grade lithium mineralised zone within the Central and North Extension zones, which remains open to the north and north-east.

Additionally, the mineralised pegmatite intersected within the northern-most drill section of the North Extension zone remains open to the north (refer Figure 4).

All drill intersections reported to date are included in Appendix 1 (refer to Table 2 and Figure 6).

Proximity to Essential Infrastructure

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

The proximity of known lithium bearing pegmatites to essential infrastructure including road, power and operational deep-sea port, in addition to a well-trained local workforce and stable, pro-mining jurisdiction of Ghana is a significant advantage for the potential rapid, low capital and operational intensity of the project.

Exploration Upside

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% Li(2) O in trenching and up to 2.95% Li(2) O in rock chip sampling at the Abonko target (refer to RNS on 9 November 2017).

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 to RNS on 7 August 2018).

Results are pending for the remainder of 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 1,704m of drilling will be reported as soon as they are received from 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.
