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

"This recent discovery is a resounding endorsement of our global search initiatives and the IronRidge team.

"We are ideally positioned to take advantage of the current and expanding renewable energy initiatives in Ghana and globally. We see huge potential in stored energy with the potential of complementing the circa 280MW solar farms spread across Ghana, including the 20MW Onyadnze solar farm within 5km of our project area.

"We look forward to working with the relevant Ghanaian authorities across the mineral and energy sectors."

Project Area and Geology

The project area is located on the southern margin of the Cape Coast Batholith, a major 100km by 200km granitic intrusive complex occurring along the southern-central coastline of Ghana and part of the West African shield. A window of older Birimian metasediments is surrounded by the batholith and occurs along the intrusive contact; possibly representing a roof pendent of older metasediments underlain by granitic intrusives.

Smaller kilometre scale, more fractionated granitic intrusive bosses occur within the metasediments and are spatially associated with pegmatitic vein swarms. These intrusive bodies are believed to be the more fractionated end-members, and accordingly more prospective zones for lithium rich pegmatites.

The project area is well located, being easily accessible within 100km from the capital city of Accra along a bitumen highway, is adjacent to grid power with transmission lines traversing the project areas and well serviced by infrastructure and logistics needs for potential rapid development.

Due Diligence Results

Results were received for technical and legal due diligence programmes completed over the Saltpond, Apam and Winneba license and application areas. Collectively, Barari, Obotan and Merlink satisfied all terms to agree binding and unconditional farm-in agreements with IronRidge.

A first pass field programme including 86 individual rock chip samples, 100m of trenching, 270m of channel sampling and over 130m width of bulk surface rock-chip sampling for a total of 1,545kg of sample (not including Quality Assurance/Quality Control 'QA/QC' samples) and reconnaissance mapping was completed across the project areas.

Reconnaissance mapping and rock-chip sampling identified prospective pegmatites within the project areas; however, returned low level anomalous lithium (Li) assay results. It was recognised that the small sample volume used in rock chip sampling combined with tropical weathering could explain the low-level anomalous Li results and a follow-up sampling strategy was required to adequately test the targets. Accordingly a combined trenching, bulk surface rock-chip sampling and channel sampling programme was designed over three selected pegmatite targets within the Barari license to confirm or otherwise high-grade lithium results.

A total of 1,545kg for 63 samples was collected at an average individual sample weight of 24.5kg, over 100m of trenching, 270m of channel sampling and 130m of surface bulk sample rock-chip sampling. All samples were delivered in their entirety to ALS Ghana for sample preparation and representative pulps sent to ALS Johannesburg for multi-element geochemical analysis by sodium peroxide fusion (ICP-OES and ICP-MS finish, lab code ICM90A) for 54 elements. 

Multiple high-grade lithium results were received over significant and continuous broad widths over two of the three pegmatites initially tested. Broad, continuous high-grade trenching results of 100m at 1.57% Li2O including 40m at 1.93% Li2O which includes 15m at 2.18% Li2O were returned. Additional surface bulk rock-chip sampling results over 10m width at 2.41% Li2O, 25m at 2.29% Li2O and 25m at 2.14% Li2O were returned from an adjacent pegmatite (see Figure 2 and Figure 4).

Additional multiple mapped pegmatites remain untested with significant lithium exploration upside within the Barari license area and across the Cape Coast project portfolio (see Figure 2).

The outcropping pegmatites are characterised by coarse crystalline spodumene (a lithium rich pyroxene mineral and the preferred feedstock of hard-rock lithium mining projects). IronRidge proposes to investigate the leaching of lithium and then to precipitate a lithium carbonate product (see Figure 3). In addition to lithium, the licenses are also prospective for tin, tantalum, niobium, beryllium, caesium and gold which occur as accessory minerals within the pegmatites and host formations. Additional anomalous beryllium and caesium was identified within the multi-element geochemistry assay results.

Historic Lithium Resource

Through the Joint Venture Agreement with Obotan Minerals and Merlink resources, the Company has secured first rights to apply for ownership of the historic Egyasimanku Hill lithium resource. The deposit was drilled by the Ghana Geological Survey during 1962 and a resource estimate of 1.48Mt at 1.66% Li2O reported (non JORC).

The Egyasimanku Hill Lithium deposit occurs within the Yenku Forest Reserve, a designated forested area set aside for the local population. Access rights for minerals exploration and development within a forest reserve are granted to an adjacent exploration license holder on approval from the Forestry Commission, Environmental Protection Agency and the local landholders. The application to access the Yenku Forest Reserve has been lodged by the Joint Venture partner and approval is pending; no certainty to the grant of access can be assigned at this stage.

The unconditional binding Farm-in and Joint Venture Agreements with Barari, Obotan and Merlink on the three license and two application areas, provides the Company with over 45km strike of prospective ground with highly anomalous due-diligence sampling results and exciting exploration targets along rediscovered lithium bearing pegmatite trends that hosts the historic 1.48Mt Egyasimanku Hill resource at 1.66% Li2O (non JORC).

In addition to the securing licenses and applications, and the first right to apply for ownership of the historic lithium resource through the Joint Venture, the Company has also submitted a license application through its wholly owned local subsidiary Green Metals Resources Ltd, over an area to the east of the historic resource and along interpreted extensions of the lithium pegmatite trend. The application is pending approval.

Next Steps

The Company and its farm-in and Joint Venture counter-parties are currently planning a staged exploration programme which will focus on advancing through detailed mapping, trenching and sampling the currently defined spodumene bearing pegmatites, whilst in parallel executing a 'ultra-high' definition magnetics and radiometrics airborne survey over the project areas to facilitate exploration target definition and target ranking. Pending results of the detailed trenching programme and exploration activities, the Company may execute a drilling programme.

Commercial Terms of Farm-in and JVA

The Company has entered into a Farm-in and Joint Venture Agreement with Obotan Minerals Ltd and Merlink Resources Ltd of Ghana, West Africa, under which IronRidge can acquire up to 100% of the projects through staged earn in arrangements and expenditure to Feasibility Study within a 4-year period subject to Obotan and Merlink retaining a NSR of 2.5% of which 50% may be acquired for US$3 million at any stage. Funding will be used to undertake further exploration work and, pending results, defining a maiden resource and complete project studies.

The Company has also entered into a Farm-in and Joint Venture Agreement with Barari Developments Limited ("BDL") of Ghana, West Africa, under which IronRidge can acquire up to 100% of the projects through staged earn-in arrangements and expenditure to Feasibility Study within a 4-year period. Barari Developments Limited will retain a Net Smelter Return Royalty ("NSR") of 2% capped at US$2m of which 50% may be acquired for US$2m at any stage. Funding will be used to undertake further exploration work and, pending results, define a maiden resource and complete project studies.

Lithium Outlook

Global demand for lithium is increasing at an unprecedented rate since the emergence of consumer electronics, the electric vehicle and energy storage markets, driven by a desire to reduce carbon emissions and improve efficiencies.

In its purified form, lithium (Li) possesses some unique characteristics. It is the lightest of all metals, has a high electrochemical potential with an exceptionally small ionic radius and therefore exceptionally high charge to radius ratio. These unique characteristics make it ideal for use in lightweight, rechargeable batteries currently undergoing rampant growth in global demand.

Lithium and its compounds have several industrial, medicinal and biological applications, including heat-resistant glass and ceramics, lithium grease lubricants, flux additives for iron, steel and aluminum production, lithium and lithium-ion batteries, mental health treatment and bacteriostatic properties. These uses consume more than three quarters of lithium production.

Commentary, from industry experts, suggests lithium consumption will increase significantly over the coming years; especially due to increasing global battery demand.

The Board is delighted with the progress that the Company has made in 2017 and looks forward to keeping shareholders updated as further news becomes available.
