Tertiary Minerals PLCÂ has reported significant progress at its Konkola West copper project in Zambia, where partner KoBold Metals is carrying out a major drilling campaign as part of an earn-in agreement.
The first drill hole, KWDD001, reached a depth of 2,711m before being terminated due to technical issues, making it the deepest mineral exploration hole recorded in the Zambian Copperbelt.
Partial assay results from KWDD001 have returned anomalous copper values, including 2,950ppm over 1.05m and up to 1,050ppm in deeper sections.
The remaining assays are expected shortly, and the data is being used to enhance geological understanding of the basin.
KoBold has now advanced a second drill hole, KWDD002, to over 1,340m. It is on track to intersect the targeted copper-bearing zone, with geological formations encountered as planned.
The agreement’s timeframe has been extended by six months to December to accommodate final results.
The project is located near several world-class copper mines, including KoBold’s Mingomba deposit.
