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

"We are pleased to report that field programmes continue to gather momentum within our Côte d'Ivoire exploration portfolio. 

"The addition of national geologists has bolstered our in-house exploration team and we have secured new office facilities in Abidjan to support our level of in-country activity.

"Detailed face mapping and channel sampling of 145 primary 'hard-rock' artisanal mining pits over a 16km strike will provide valuable insights into gold mineralised structures where intensely, steep dipping sheared and brecciated quartz vein zones have been mapped at the Zaranou Gold Project.

"We initiated and completed 3,903m of AC drilling before the onset of the wet season at the Bianouan and Bodite license areas to test the highest priority coincident soils, trenching and auger gold anomalies; assays are pending.

"Finally, we are advancing our Kineta-Marahui portfolio where trenching has returned encouraging initial trenching intersections including 2m @ 4.04g/t gold."


 Exploration Project Updates

The Company has been diligently advancing its exploration portfolio in Côte d'Ivoire and provides herewith and update on activities.

Refer to RNS of 12 June 2019 for an update on the Vavoua gold portfolio where Southern Geoscience Consultants of Perth, Western Australia, recently completed a litho-structural interpretation and targeting exercise. Field mapping teams have now covered 227km2; approximately 32% of the granted Vavoua license area.

Refer to Figure 1 below for license areas reported on herewith.



Field teams have completed detailed face mapping and channel sampling over 15 large scale and 130 small scale artisanal pits for a total 145 primary 'hard-rock' artisanal mining pits within the north-eastern half of the Zaranou license. A total of 324 samples including 144m of channel sampling and Quality Assurance/ Quality Control ('QA/QC') samples have been submitted to the lab for gold assay.

Detailed face mapping of primary 'hard-rock' artisanal pits has provided valuable insights into potential mineralised structures, vein types and true mineralised widths pending receipt of assays (refer to Figure 2).


Bianouan and Bodite:

A total of 1,415m of AC drilling for 28 holes to an average of 50m depth was completed at Bianouan. Drilling was designed to test coincident soils, auger and trenching gold geochemical anomalies at depth.

At Bodite a total of 2,488m for 37 AC holes was drilled to an average depth of 30m to test the highest priority soil geochemical anomaly.

A total of 2,123 samples including QAQC samples have been submitted to the lab for assay.


Kineta and Marahui Portfolio:

At Kineta the Company has received multiple narrow gold intersections in trenching, including 2m @ 4.04g/t gold and 6m @ 0.24g/t gold. All trenching intercepts are reported in Figure 3 below at a 0.12g/t gold cut-off with maximum 2m of internal dilution.

At Marahui a total of 5,129 soil samples, including QA/QC samples, have been collected on initial 400m x 25m spaced lines and subsequently infilled to 200m and 100m line spacing across prospective trends.

Significant soil anomalies between 30ppb to 2,500ppb gold have been defined over broad NNE trending 2km strikes and 100m to 200m widths (refer Figure 4).



Next Steps:

The Company is planning infill AC drilling fences at Kineta to further test the mineralised trends and better test for high-grade gold shoots at depth.

At Marahui the Company will plan trenching or AC drilling to test the highest priority soil anomalies.

At Zaranou the Company is planning infill AC drill hole fences to test for mineralisation width and continuity within high-priority zones highlighted in channel and rock-chip sampling assay results. Concurrently, the Company is planning a drone survey for accurate topography in addition to detailed air photography.

At Bianouan and Bodite the Company is awaiting results of the aircore programme before planning the next steps.


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.

IronRidge Resources is an AIM-listed, Africa focussed minerals exploration company with a lithium pegmatite discovery in Ghana, extensive grassroots gold portfolio in Cote d'Ivoire and a potential new gold province discovery in Chad. The Company holds legacy iron ore assets in Gabon and a bauxite resource in Australia. IronRidge's strategy is to create and sustain shareholder value through the discovery and development of significant and globally demanded commodities.




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 deposit, estimated to be in the order of 1.48Mt at 1.67% Li2O and surrounding tenements. The portfolio covers some 684km2 with the newly discovered Ewoyaa project including drill intersections of 128m @ 1.21% Li2O from 3m and 111m @ 1.35% Li2O from 37m, and a further identified 20km strike of pegmatite vein swarms. The tenure package is also highly prospective for tin, tantalum, niobium, caesium and gold, which occur as accessory minerals within the pegmatites and host formations.




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.
