Update on Cape Coast lithium portfolio, Ghana

Published by , Editorial Assistant
Global Mining Review,

IronRidge Resources has provided an exploration update for its Cape Coast Lithium Portfolio in Ghana.


  • Reverse circulation (RC) drilling ongoing with over 8000 m drilled to date of a planned 13 200 m third phase programme.
  • Multiple visual spodumene bearing pegmatite zones intersected in drilling at Ewoyaa North, Ewoyaa North-East and Abonko; assays pending.
  • New coarse spodumene bearing pegmatite discovered in outcrop and trenching at the Kaampakrom target 1 km north of resource drilling at Ewoyaa, with over 250 m strike and possible extensions to 500 m. Trenching is underway and mineralisation open in both directions.
  • Drill access and prospecting drill pads completed at the Kaampakrom target; drilling imminent.
  • New pegmatite discovery at the Ndasiman target approximately 10 km west of Ewoyaa; trenching defines 700 m strike and up to 100 m apparent width.
  • New pegmatite discovery at the Krofo target approximately 3 km northwest of Ewoyaa; trenching defines 400 m strike and up to 25 m apparent width.
  • Wet season environmental and social baseline draft report received from Ghanaian consultancy NEMAS Consult; dry season baseline studies to commence.
  • Targeting maiden mineral resource estimate for 1Q20 lithium hydroxide conversion test work at ANSTO underway.

Commenting on the Company’s latest progress, Len Kolff, Chief Operating Officer of IronRidge, said: “Drilling is progressing well with approximately a third of the planned RC and diamond programme remaining. We are pleased to report that drilling has defined new pegmatite zones along the known Ewoyaa deposit footprint, with visual spodumene in RC drill chips and assays pending.

“Ongoing exploration activities; running concurrently with the drill programme and bolstered by an additional dedicated geologist has delivered multiple new pegmatite discoveries at Kaampakrom, Ndasiman and Krofo.

“Target areas prioritised on the basis of the regional soils programme including in-house laser-induced breakdown spectroscopy (LIBS) and portable X-Ray Florescence (pXRF) analysis complemented by the regional airborne magnetics survey and reconnaissance field mapping are delivering new pegmatite discoveries; vindicating the methodology and highlighting multiple new target areas. 

“The Kaampakrom discovery is especially encouraging given the coarse visible spodumene in outcrop and trenching, and close proximity to the current drilling underway at Ewoyaa 1 km away.

“The scale of the Ndasiman pegmatite discovery is promising, with pegmatite exposed in trenching over 700 m strike and up to 100 m apparent widths, with assays pending to confirm whether it is lithium bearing.

“The Krofo discovery which is within 3 km from the Ewoyaa deposit footprint is encouraging and provides further prospectivity within the Cape Coast pegmatite field for additional discoveries.

“The Ghana field team has done a great job in advancing the resource drilling programme and the exploration pipeline through diligent, staged field work where results demonstrate further exploration upside within the Cape Coast lithium portfolio.”
