High-Grade Lithium Pegmatite Drilling Success In Ghana
IronRidge Resources Limited (AIM: IRR) has unveiled final high-grade lithium pegmatite drill intersections at new targets adjacent to the Ewoyaa Lithium Project in Ghana, West Africa.
At Ewoyaa the company has defined a JORC compliant mineral resource estimate of 14.5Mt at 1.31% Lithium Oxide (Li2O) in the inferred and indicated category, including 4.5Mt at 1.39% Li2O in the indicated category.
- Highest metal content intersection (lithium grade multiplied by meters) reported to date in the resource expansion programme of 53m at 1.34% Li2O from 80m in hole GRC0392.
Additional high-grade lithium pegmatite intersections reported in reverse circulation (“RC”) drilling results at the Ewoyaa North target adjacent to the ELP, including highlights at a 0.4% Li2O cut-off and maximum 4m of internal dilution of:
o GRC0392: 53m at 1.34% Li2O from 80m
o GRC0393: 32m at 1.34% Li2O from 87m
o GRC0393: 19m at 1.17% Li2O from 56m
o GRC0392: 13m at 0.93% Li2O from 25m
o GRC0391: 12m at 0.93% Li2O from 84m
o GRC0390: 11m at 1.01% Li2O from 66m
Additional high-grade lithium pegmatite intersections reported in RC drilling results at the Grasscutter target adjacent to the ELP, including highlights at a 0.4% Li2O cut-off and maximum 4m of internal dilution of:
o GRC0374: 28m at 1.35% Li2O from 97m
o GRC0377: 19m at 1.37% Li2O from 76m
o GRC0397: 15m at 1.6% Li2O from 136m
o GRC0369: 12m at 1.44% Li2O from 70m
o GRC0372: 11m at 1.29% Li2O from 105m
o GRC0398: 11m at 1.29% Li2O from 78m
o GRC0399: 11m at 1.24% Li2O from 78m
o GRC0377: 6m at 2.12% Li2O from 102m
o GRC0384: 13m at 0.97% Li2O from 147m
o GRC0384: 8m at 1.56% Li2O from 135m
o GRC0370: 9m at 1.37% Li2O from 129m
o GRC0385: 10m at 1.17% Li2O from 158m
o GRC0388: 10m at 1.11% Li2O from 58m
CEO, Vincent Mascolo, said a 25,612m resource expansion programme is now completed with infill resource drilling and metallurgical diamond core drilling now underway with five drill rigs on site.
“We have returned our best drill intersection to date with the highest metal content observed (lithium grade multiplied by meters) for the resource expansion programme at the Ewoyaa North target,” he said.
“The resource expansion drilling programme has now been completed and we will maintain momentum with five drill rigs currently active on site for the resource infill programme.
“The board remains confident the additional exploration targets will increase resource scale and improve project economics, where we have defined Ghana’s first lithium JORC compliant resource of 14.5Mt at 1.31% Li2O, within 110km of an operating deep-sea port.
“Infill resource, metallurgical and hydro monitoring drilling is well underway in addition to metallurgical test-work in support of planned Feasibilty Studies.
“The Company is ideally positioned to take advantage of the increasing demand for lithium due to its role in the stored energy transition and looks forward to keeping shareholders up to date as the Ewoyaa Project progresses.”
