Significant Trenching Intersections and Drill Programme

Ewoyaa West Target - Cape Coast Lithium Portfolio

Ghana, West Africa

 

IronRidge Resources Limited (AIM: IRR, 'IronRidge' or the 'Company'), the African focussed minerals exploration company, is pleased to announce that trenching has defined wide and long pegmatite intersections at the Ewoyaa West target, just one of the multiple pegmatite targets within the Cape Coast Lithium Portfolio, located in Ghana, West Africa.

 

HIGHLIGHTS:

 

Ø Over 940m of new trenching completed and 1,640 pits dug over the Ewoyaa Project area; both ongoing as an effective exploration tool.

Ø Continuous pegmatite intersected in trenching and pitting over 840m strike length and up to 100m wide on surface at the newly defined 'Ewoyaa West' target.

Ø Additional extensions for a further 1.25km strike defined in pitting to the south of the Ewoyaa West target.

Ø Ewoyaa West target is within 540m from the main Ewoyaa Project and dipping shallowly to the east.

Ø Additional trenching has also intersected 65m of pegmatite at the new 'Ewoyaa Middlings' target which lies in-between Ewoyaa and Ewoyaa West; trenching ongoing with the potential to add significantly more pegmatite.

Ø Phased 13,200m Reverse Circulation ('RC') and Diamond Core Drilling ('DD') drill programme designed dependent on initial drilling results, to test new targets as well as strike extensions at the Ewoyaa and Abonko deposits.

Ø Weather permitting, drilling to commence during Q3 2019; access and drill pad planning underway.

Ø Ghanaian environmental consultancy NEMAS engaged and baseline environmental and social studies commenced.

Commenting on the Company's latest progress, Len Kolff, Chief Operating Officer of IronRidge, said:

 

"Pegmatites often occur in clusters and pitting and trenching are proving to be a successful tool for defining additional pegmatites within the immediate Ewoyaa Project area through weathered cover where no outcropping pegmatite is visible.

 

"We have effectively increased the known outcropping pegmatite surface area by approximately 50% with the addition of the Ewoyaa West target and with trenching ongoing at the Ewoyaa Middlings target there is potential for further increases.

 

"We have planned a phased RC drill programme to test the new targets as well as extensions at the Ewoyaa deposit, with drill access and pad planning underway, and commencement of drilling planned for Q3 2019 weather permitting.

 

"Given the Projects significant mineralised intersections, positive metallurgical results, proximity to infrastructure and favourable jurisdiction, we are pleased to have awarded long lead environmental and social baseline studies for future mine permitting to Ghanaian consultants NEMAS Ltd which have now commenced."

 

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

 

"The discovery of Ewoyaa West and Ewoyaa Middlings targets is extremely encouraging, and we look forward to the next phase of drilling.

 

"The decision to advance the Ewoyaa Project area ahead of a maiden resource estimate was predicated by the ongoing success with the discovery of new pegmatites in the immediate project area, exceptional metallurgical test work results and a robust treasury."

 

 

New Target Areas

Ongoing pitting and trenching activities within the Ewoyaa Project area has defined over 840m strike of continuous weathered pegmatite up to 100m wide at surface at the Ewoyaa West target, which dips shallowly towards the east. A total of 525m in four (4) trenches was completed at the Ewoyaa West target (refer Figure 1).

 

Additional pegmatite has been intersected in pitting to the south, providing potential for a further total of 1.25km strike at the Ewoyaa West target (refer Figure 1).

 

A fifth trench was extended 190m east to test pitting intersections in-between Ewoyaa and Ewoyaa West. Over 60m of continuous weathered pegmatite was intersected in the fifth trench which remains open to the north and south in what is now called the Ewoyaa Middlings target (refer Figure 1).

 

Both new targets coincide with a low-lying ridge, with no pegmatite visible at surface. This is significant as it increases the potential for additional 'blind' pegmatite discoveries that have not yet been tested by pitting. Additional sub-parallel ridges are evident within the topography in the immediate project area which will be tested by ongoing pitting programmes (refer Figure 2). 

 

The newly identified pegmatite zones are significant as they enlarge the surface area by 50% within the immediate Ewoyaa project area; allowing for potential resource increases and within easy trucking distance for potential future mine development.

  

Not only does pitting and trenching provide valuable geological observations of the pegmatites which are otherwise not seen at surface nor in auger drilling programmes, but it also provides youth employment within the local communities rather than utilising machinery (refer Figure 3).

 

Drill Planning

A phased Reverse Circulation ('RC') and Diamond Core Drilling ('DD') drill programme has been designed to test the Ewoyaa West target, Middlings target and strike extensions over the known Ewoyaa and Abonko deposits. Final meterage will be commensurate with initial confirmation of spodumene or other lithium mineral phases below base of weathering at Ewoyaa West and Middlings targets to justify the second phase.

 

Additional DD drilling has been planned over the Ewoyaa West target and Abonko for future metallurgical test-work and geological control.

 

Drilling is planned to commence during Q3 2019 after the current wet season, weather permitting. Drill access and pad planning is underway and a total 13,200m of RC and DD drilling has been planned (refer Figure 3).

 

Location

The Ewoyaa deposit is well located within 1km of a bitumen highway and adjacent to grid power, within 100km of an operating deep-sea port and within the pro-mining, stable jurisdiction of Ghana (refer Figure 4). Multiple additional pegmatite targets occur adjacent to Ewoyaa including the drill tested Abonko deposit, the developing Ewoyaa West target and additional exploration targets, as well as the historical Egyasimanku Hill deposit (1.48Mt @ 1.66% Li2O, non JORC) further to the east.
