Numerous broad pegmatite intersections discovered at Ewoyaa Project

Global Mining Review,

Australian minerals exploration company IronRidge Resources Ltd (IronRidge) has announced multiple, broad visible pegmatite intersections in reverse circulation drilling currently underway at the Ewoyaa Project in Ghana (West Africa).

Chief Geologist of IronRidge, Len Kolff, commented on the company's latest progress, stating: "130 m of continuous visible pegmatite from surface in RC drilling is a very significant drill intersection; notwithstanding multiple additional visible pegmatite intersections including 62 m and 40 m in the first nine holes drilled."


"True pegmatite widths have been interpreted between 20 m to 60 m, with drilling having tested to 140 m vertical depth and >300 m strike, and mineralisation open down dip and along strike.


"With assays pending within the next two months and the high-grade surface trenching results reported previously including 100 m @ 1.57% Li2O (including 40 m at 1.93% and 15 m at 2.18% Li2O), we are eagerly awaiting the results.


"The proximity of the project to an operating port, the national highway and grid power within the pro-mining jurisdiction of Ghana is potentially a real positive."

  Drilling Update, Ewoyaa Project

According to IronRidge, multiple, broad visible pegmatite zones have been intersected in the first nine reverse circulation (RC) holes completed over the central zone of the Ewoyaa Project. The first phase 5000 m drilling programme is ongoing, currently assessing the southern and northern zones of the Ewoyaa Project and expected to be completed within the coming months.


Significant visible pegmatite intervals have been observed in RC drill chips, including a continuous pegmatite interval over 130 m from surface in hole GRC0004, a 62 m interval from 58 m depth in hole GRC0007 and a 40 m interval from 128 m depth in hole GRC0008.


An initial interpretation of the visual drilling results suggests true pegmatite widths within the central zone of 20 m to 60 m to depths greater than 140 m and over a minimum 300 m strike, with mineralisation open in all directions.


Samples from the first nine RC drill holes have been sent to SGS Ghana for sample preparation and analysis in SGS South Africa. Results are expected within one to two months.
