Ewoyaa Project Drilling Update - Final Results Received

Most Significant Drill Intersection Reported to Date at

Ewoyaa Project - Cape Coast Lithium Portfolio

Ghana, West Africa

IronRidge Resources Limited (AIM: IRR, 'IronRidge' or the 'Company'), the African focussed minerals exploration company, is pleased to report that it has received final assay results from its third phase drilling programme campaign at the Ewoyya Lithium Project (the "Ewoyaa Project"). The results, obtained through a Diamond Drilling ('DD') programme, returned high-grade intersections with the most significant drill intersection reported to date at the Ewoyaa Project within the Cape Coast Lithium Portfolio in Ghana, West Africa.

HIGHLIGHTS:

Ø Broad and high-grade results returned for Diamond Drilling ('DD') programme completed at the Ewoyaa Project; representing the final drilling results received for the third phase programme

Ø Total of 350m of diamond drilling completed in two (2) drill holes as part of the third phase programme and reported herewith

Ø High-grade drill intersections* reported at Ewoyaa in diamond drilling including:

o GDD0010: 76m @ 1.81% Li2O from 43m

o GDD0010: 33.5m @ 1.3% Li2O from 124m

o GDD0011: 69.74m @ 1.45% Li2O from 15.86m

o GDD0011: 31.4m @ 1.78% Li2O from 92.6m

Ø Highest lithium grade x length of mineralised interval ('metal endowment') reported to date in a single drill hole at the Ewoyaa Project; 76m @ 1.81% Li2O and 33.5m @ 1.3% Li2O in hole GDD0010

Ø Visual observations re-confirm coarse spodumene as the dominant lithium mineral phase; in-line with previously reported metallurgical test-work results where greater than 6% Li2O concentrates at up to 85% recovery can be generated using DMS gravity separation at a coarse 6.3mm crush (refer RNS of 21 May 2019)

Ø Targeting JORC compliant Maiden Mineral Resource Estimate ('MRE') for Q1 2020

*Reported at a 0.4% Li2O cut-off with maximum 4m of internal dilution

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

“The latest diamond drilling results from the third phase drilling programme have delivered robust drill intersections and are our highest Li2O grade x length of mineralised interval (‘metal endowment’) reported to date in a single drill hole at the Ewoyaa Project; 76m @ 1.81% Li2O and 33.5m @ 1.3% Li2O in hole GDD0010.

“Visual observations from both diamond drill holes reconfirms that coarse grained spodumene is the dominant lithium phase at the Ewoyaa Project; in-line with previously reported metallurgical results where greater than 6% Li2O concentrates with low contaminants and up to 85% recoveries can be generated at a coarse 6.3mm crush and using DMS gravity separation (refer RNS of 21 May 2019).

“Additionally, infill hole GDD0010 has confirmed continuity of mineralisation and grade within the central zone of the Ewoyaa Main deposit, where the majority of the Indicated category resource will be estimated.

“We are now working towards delivering the maiden MRE in Q1 2020. In the meantime, field teams continue to develop and advance the project portfolio with ongoing regional exploration programmes, baseline monitoring and drill site re-vegetation works.”

Diamond Drilling Results - Third Phase Programme

The Company has now completed its third phase drill programme for a total of 12,669m of Reverse Circulation ('RC') in 97 holes and 350m of Diamond Drill core ('DD') in two (2) holes. The Company has drilled three phases of RC and DD drilling to date for a total of 25,563m of RC in 198 holes and 1,394m of DD in 11 holes (refer RNS' of 28 August 2018, 8 October 2018, 20 November 2018 and 5 March 2019).

Results reported herewith are for the DD component of the third phase drilling programme completed at the Ewoyaa project and represent the final results to be reported for this programme.

Hole GDD0010 was designed as part of an infill drill section to provide a higher degree of geological confidence as well as provide future metallurgical test-work drill core sample and geotechnical data. Hole GDD0011 was drilled perpendicular to the current drill grid at Ewoyaa Main and within the likely zone of an Initial Mining Area ('IMA') at the Project to provide confidence in the geological model, additional geotechnical data, as well as additional future metallurgical test-work sample material.

Hole GDD0010 is significant as it represents the highest grade 'metal endowment' (Li2O grade_% x interval_m) combined intersection received to date within a single drill hole at the Ewoyaa Project.

Both holes intersected broad and high-grade widths of coarse spodumene pegmatite mineralisation from near surface which provides confidence in the likely IMA location within an area of infill drilling, as well as re-confirming coarse spodumene as the dominant lithium mineral phase and amenability to a simple gravity process flow-sheet design (refer RNS of 21 May 2019).

All DD drill intersections at a 0.4% Li2O cut-off and maximum 4m of internal dilution are summarised in Table 1 below and in Figure 1.

All drill intersections for the third phase combined RC and DD programme are summarised in Table 2 and Figure 3 (refer RNS of 25 November 2019).

Table 1: All reported Diamond Drill intersections at a 0.4% Li2O cut-off and maximum 4m of internal dilution from Phase 3 DD programme

The reported intersections and visual observations in diamond drill core have added considerable confidence in the geological model and continuity of mineralisation within the central portion of the Ewoyaa Main deposit. This is where the majority of the RC infill drilling has been completed to date and will be the focus for the indicated portion of the JORC compliant MRE.

The diamond drill holes will provide metallurgical test-work sample material as well as valuable geotechnical assessment for future studies.

Next Steps

The Company is compiling and reviewing all of the geological data in preparation for the MRE. All of the data and geological interpretations will be provided to the Competent Person for resource estimation. The Company is targeting release of the MRE for Q1 2020.

The Company will use this time wisely to advance the projects whilst maintaining field activities and managing budgets carefully. Field teams will continue to progress the exploration programmes, baseline monitoring and drill site remediation activities including re-planting.

The Board is delighted with the progress that the Company has made in 2019 to date and looks forward to keeping shareholders updated as further news becomes available.
