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

"We have worked closely with our partners to secure the necessary approvals to allow us to commence earthworks and drilling; the next crucial step in confirming Ewoyaa as a significant lithium discovery.

Additionally, we have diligently used the intervening time to advance the portfolio; establishing a local office, community consultations and detailed orientation surveys over known deposit footprints to provide a cost effective blueprint for future exploration success and discovery over our portfolios in Ghana and Ivory Coast.

We have renewed the Forest Entry permit and submitted a license application over Egyasimanku Hill, whilst recovered historical Geological Survey maps, coupled with the helicopter geophysical survey, have highlighted additional exploration upside.

We look forward to updating the market when news becomes available on our application for the exploration license."

Earthworks, Drilling and Geology Update:

Relevant approvals have been received allowing earthworks and drilling to commence over the Ewoyaa pegmatite target. All community consultations and landholder negotiations have been completed and a dozer mobilised to site to commence drill access and drill pad construction.

Earthworks are expected to take between two and three weeks to complete with a multi-purpose drill rig targeted to commence drilling late April to early May 2018.

Whilst waiting for the necessary approvals, the Company has completed 428 pits in addition to trenching (as announced on 9 November 2017) to better define surface geology at the Ewoyaa and Abonko targets.

The factual observations from pitting and trenching has allowed for a detailed surface geology re-interpretation of the targets; defining three significant spodumene bearing pegmatite zones at Ewoyaa with a combined 1,600m strike length. The largest central zone spodumene bearing pegmatite is 840m long and up to 90m wide at surface, with the potential to host significant tonnage (refer Figure 2).

Approximately 7,000m of RC-DD drilling has been planned over two phases at the Ewoyaa target, with a total of 60 drill holes to an average depth of approximately 130m planned and dependent on results of the first phase (refer Figure 2).

Orientation Study - Blueprint for Lithium Exploration Ghana & Ivory Coast:

The Company completed a detailed orientation survey over the Ewoyaa deposit footprint including orientation soil sampling traverses which were sent to the lab for lithium analysis. Results demonstrated that the Ewoyaa pegmatite footprint coincides with a clearly defined lithium soil anomaly. A trial using a Reflex hydraulic PRESS and SciAps Z300 hand held lithium analyser was completed on the same sample suite with results comparing favourably to laboratory assays.

The Company has subsequently purchased and commissioned a Reflex hydraulic PRESS and SciAps Z300 portable lithium analyser; both based at the Mankessim field office in Ghana to service extensive regional exploration soil sampling programmes over the Ghana and Ivory Coast lithium portfolios. This has been implemented to rapidly and cost-effectively assess the Company's lithium portfolio at the exploration stage and define potential trenching and drilling targets.

A dedicated team of lab technicians has been recruited and is being trained locally to implement this long term vision and forms part of an important strategy within the Company of recruiting, training and empowering members of the local communities within which it operates (refer Figure 3).

Egyasimanku Hill Update

The Company successfully renewed its Yenku Forest Entry permit, allowing field mapping to resume over the Egyasimanku Hill target. Concurrently, the Company recovered historical 1960's Geological Survey maps and cross-sections over the Egyasimanku Hill lithium pegmatite target; detailing historical trenching and drilling locations and identifying the zone over which the historical deposit of 1.48Mt @ 1.67% Li2O was estimated (non JORC compliant).

The Company has re-deployed geologists to the site to resume mapping and sampling of historic trenches as well as following up high-priority geophysical anomalies within the immediate area. Concurrently, the Company has submitted an exploration license application over the area.

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.
