Gold Portfolio Update, Chad, Central Africa

High-Grade Assay Results at Dorothe Prospect

New Licenses Granted - Extensive Artisanal Workings Mapped

IronRidge Resources Limited (AIM: IRR, 'IronRidge' or the 'Company') is pleased to provide an update on its gold portfolio in Chad, Central Africa. High-grade rock-chip assay results with grades of up to 39g/t gold have been received from new artisanal workings within the Dorothe prospect, as well as anomalous 1g/t gold from outcrops to the south of the Dorothe prospect. Additional anomalous copper grades of up to 1.05% have been received from rock-chip samples over a pXRF soil anomaly to the south-west of the Dorothe prospect. Two new licenses have been granted to the wholly owned Tekton Minerals with extensive artisanal workings and visible gold mapped.

HIGHLIGHTS:

Ø Rock-chip assay results received from mapping within the Dorothe license; steady flow of trenching and soil sampling results are expected over the coming months.

Ø High-grade assay results up to 39.1g/t gold (789g/t Ag, >20% Pb & 0.48% Cu) from rock-chips within new artisanal workings at the Dorothe prospect, first announced 23rd November 2017.

Ø Additional anomalous rock chips up to 1.1g/t gold returned from the 'Camp One Vein' prospect; potential southern extension of the Dorothe prospect, first announced 1st February 2018.

Ø Anomalous copper grades of up to 1.05% returned from two reconnaissance rock chip samples over a 2km x 1.5km soil anomaly using a Portable x-ray fluorescence device, ("pXRF"), first announced 1st February 2018 and coincident with a biotite gneiss intrusive body; may indicate potential for a bulk tonnage copper target.

Ø New exploration license granted at Kalaka and Nabagay reconnaissance license successfully converted to an exploration license, consolidating the Company's ground position within the prospective corridor.

Ø Two new artisanal mining centres, now largely abandoned, have been defined within the newly granted Kalaka license, approximately 6km and 15km along strike from the Dorothe prospect.

Ø Main Kalaka artisanal workings occur over a 1km x 1km area and occur within a large scale fold closure with visible gold observed from artisanal miners.

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

"High-grade rock chip results up to 39.1g/t gold from new workings occuring within the Dorothe prospect continue to reinforce Dorothe as a high-priority target; we eagerly await assay results for the 9,270m of trenching completed.

"New targets to the west and south of the Dorothe prospect have delivered encouraging results, ranging from 1.05% copper and up to 1.1g/t gold in rock chips, further highlighting the exploration potential within the portfolio.

"Securing the Kalaka license has been a key focus; we are very pleased to consolidate the Company's position along this highly prospective and underexplored gold corridor."

"Field programmes for the 2017-2018 season are approaching completion prior to the commencement of the wet season, and with the reporting of initial assay results, we are anticipating regular news-flow as trenching and soil sampling results are received."

High-Grade Assay Results:

Assay results have been received for the initial mapping and rock-chip sampling programmes completed within the Dorothe license, prior to the commencement of trenching and concurrent with regional soil sampling programmes.

High-grade results of up to 39.1g/t gold, 789g/t Ag, >20% Pb and 0.48% Cu were returned from rock-chip samples collected within new artisanal workings at the Dorothe prospect, as first announced on 23rd November 2017. In addition to the vein material reported, rock-chip samples of the host rock with moderate to intense alteration, indicating mineralised fluid flow outside the vein, reported up to 1.27g/t Au, 8.1g/t Ag, 1840ppm Pb, 274ppm Cu (refer Figure 1).

Approximately 1.5km south of the Dorothe prospect, rock-chip samples over the 'Camp One Vein' prospect (as announced on 1st February 2018) returned anomalous gold results including 1.1g/t Au with 12g/t Ag and 1g/t Au with 6g/t Ag over a 1km strike and representing potential southern extensions of the Dorothe prospect (refer Figure 2).

In addition to the high-grade gold results at Dorothe, the Company has received encouraging copper assay results including grades of 1.05% copper from two reconnaissance rock-chip samples collected over pXRF identified copper in soil anomaly found during routine regional soil sampling (refer Figures 3 and 4, and as announced on 1st February 2018).

Although at an early stage, the results highlight the potential for a possible bulk tonnage copper target where the pXRF soil anomalism as announced on 1st February 2018 is coincident with a biotite gneiss intrusive body, and highlights the exploration potential for additional minerals and metals within the Chad portfolio.

New License Granted - Extensive Zone of New Artisanal Workings

In line with IronRidge's strategy to secure, and in a timely and proficient manner, explore highly prospective large scale scale projects, the Company has successfully secured the Kalaka license whilst concurrently transferring the Nabagay reconnaissance permit to an exploration license; thus consolidating the Company's position along this highly prospective gold corridor (refer Figure 5).

The newly granted licenses have been ratified into the Company's exploration and mining convention, whilst the Ade license has been relinquished in favour of the Kalaka license consolidation. The Company's exploration portfolio now covers a combined surface area of 900km2 along highly prospective structures and lithological contacts with extensive artisanal workings.

Recent mapping and aerial drone surveys have highlighted two extensive artisanal mining centres, now largely abandoned at Kalaka and Guerere; approximately 15km and 6km north of the Dorothe prospect respectively . The Guerere workings, first announced on 12th June 2017, extend into the southern tip of the newly granted Kalaka license and was an important observation in the consolidation of the area between the Dorothe and Nabagay licenses.

All largely abandoned artisanal mining centres occur within favourable structural settings within large scale fold closures in the interpreted hangingwall block of a major north-south trending fault structure. At Kalaka, artisanal workings occur over a large 1km x 1km area, indicating the potential large scale of a mineralised system below (refer Figure 6).

The Board is pleased with the progress that the Company has made in 2018 to date and looks forward to keeping shareholders updated as further news becomes available.
