Ø 51,539m AC and RC drilling programme now completed across the Mbasso, Ehuasso, Ebilassokro and Yakassé targets and a further three hole 645m diamond drilling ("DD") programme completed at Ehuasso for geology, density and twinning of RC holes with assay results pending.

 *incorrectly reported as 28m at 4.07g/t Au from 124m in RNS of 18 January 2021, with a lower metal content than currently reported

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

"Ongoing results from the current drilling programme have confirmed significant mineralisation potential at the Mbasso target.

"Our 'early ounces' strategy continues to target weathered oxide mineralisation, with initial observations suggesting it continues to average depths of 50m and up to 90m, which we believe is indicative of simple mining and processing at low operational and capital costs.

"With only 12km of the 47km of identified strike having been drill tested to date, an additional 8km strike of hard-rock artisanal workings and 27km of soil anomalies remain untested, with the potential to deliver a pipeline of further discoveries along this considerable mineralised structure.

"The AC and RC drilling is now complete across the Mbasso, Ehuasso, Ebilassokro and Yakassé targets for a total of 51,539m in addition to a 645m DD programme completed at the Ehuasso target for geology, density and twinning of select RC holes for resource estimation."

High-Grade Results within New Target Areas

Remaining 4m composite RC and AC results for the completed drilling programme at the Zaranou license have been received and are displayed in Figure 1 and Table 1 below. Drilling has returned multiple gold intersections at the Mbasso target and extended mineralisation further north-east over a total 2.1km strike.

The planned drill programme across the Mbasso, Ehuasso, Ebilassokro and Yakassé targets has now been completed for a total of 51,539m, of which 31,216m in 611 AC holes and 20,323m in 110 RC holes were drilled. All 4m composite samples have now been received and reported herewith, with the final 1m primary sample assays pending.

In support of better geological understanding on the controls on mineralisation, density measurements and twinning of select RC holes, a 645m three-hole diamond drilling programme was completed at the Ehuasso target with assays pending.

Highlight gold drill intersections at greater than 5 gram-metres for the 4m composite results in RC and AC drilling at the targets, are reported in Table 1 and summary Figure 1 below. All intersections reported in Table 1 and Appendix 1 are at a 0.1g/t cut-off and maximum 4m of internal dilution for the 4m composite samples.

All RC and AC sampling was completed at the drill site and consisted of initial 4m composites submitted for analysis, of which all composites greater than 0.1g/t gold will be re-submitted for analysis at 1m intervals from retained primary samples at the project site. ALS laboratory completed sample preparation in Côte d'Ivoire and sample analysis in Burkina Faso, with results passing internal and laboratory QA/QC protocols, providing confidence in reported results. All AC and RC drilling to date has been completed at -55 to -60 degrees dip.

Cross sections for reported drill results are included in Appendix 2.

New drilling results reported herewith confirm mineralisation potential at the Mbasso target with good continuity confirmed in up to five interpreted structures over a 2.1km strike in 160m spaced AC drill traverses. Newly reported results at the Mbasso target include 4m at 21.4g/t from 24m in hole ZAAC1112 and 12m at 6.1g/t from 36m in hole ZAAC0979 (refer Figure 2 and cross sections Appendix 2).

The Mbasso-Coffee Bean-Ehuasso targets cover a combined strike of 8km, centralised over the robust Coffee Bean magnetic anomaly (refer RNS of 11 November 2019), with high-grade drilling results to date following structures visible within the aeromagnetics data (refer Figure 2).

The previously reported drill intersection in hole ZARC0100 at the Yakassé target (refer RNS of 18 January 2021) was reported prematurely without all results received to the end of hole. The revised intercept reported for hole ZARC0100 at the Yakassé target is 36m at 3.7g/t Au from 124m; an improved gram x meter gold content from 114gxm to 132gxm (refer Figure 3). The intersection is highly encouraging given it is located at depth within fresh bedrock with mineralisation remaining open along strike to the north and currently defined over a 200m strike.

Drilling Programme

The third phase AC-RC drill programme across the Mbasso, Ehuasso, Ebilassokro and Yakassé targets has now been completed for a total of 51,539m of which 31,216m in 611 AC holes and 20,323m in 110 RC holes were drilled.

A 645m diamond drilling programme for three holes has been completed at the Ehuasso target for an improved geological understanding on the controls on mineralisation, density measurements and twinning of select RC holes with assays pending.

All target areas occur along a 47km striking shear structure along the length of the Zaranou license with regional soils confirming prospectivity along the structure and key target areas, as well as previous drilling completed within zones of hard rock artisanal workings (refer Figure 4).
