CuFe identifies 47% niobium, 9% tantalum in North Dam

CuFe identifies 47% niobium, 9% tantalum in North Dam

CuFe (ASX:CUF) reports that a selective sample of columbite from weathered pegmatite has returned niobium content of 47.1% and tantalum of 9.01% following exploration activities within E15/1495 at North Dam.

CuFe director Mark Hancock says the North Dam team’s recent work further illustrates the property’s potential.

“And although the results come from a columbite chip, it demonstrates the potential of the pegmatites throughout the residence to host critical minerals other than lithium,” he says.

“We are eager to commence our first drilling program to further understand the potential of the region.”

According to an ASX announcement on May 28, 2024, a soil geochemistry survey, detailed pegmatite mapping and rock chip sampling were conducted to identify the source pegmatites that likely shed the columbite and tantalite rock chips along a narrow 97 meter streambed, yielding a 43.93% yield yielded. Nb and 14.53% Ta.

A recent chip sample ND11 of columbite was collected directly from an outcrop pegmatite located near the Niobium soil anomaly and 100 meters southeast of S254.

The selective sample of columbite from weathered pegmatite is biased and does not represent the true concentration of total pegmatite, but yielded a niobium content of 47.1% and tantalum of 9.01%.

Wider zones of anomalous niobium (>15 ppm and >20 ppm) from soil geochemistry have been interpreted to coincide with outgrowth pegmatites. These pegmatites to the west will both be mapped in detail for the presence of columbite and drill holes are planned to intersect them as part of the wider RC programme, which focuses primarily on Li2O.

A preliminary report has been received for the recent heritage survey and supports the implementation of the planned activities. The final report is expected this month.

Following this, preparatory work will be carried out prior to the mobilization of the drilling contractor, with drilling expected to commence in July.

Infill soil sampling work to support the definition of the priority boreholes has now been completed and results will be incorporated into the drilling plans once received.
