Metalex tests another kimberlite target in Angola

Metalex Ventures said the current drill programme at its Angolan project is focused on testing large geophysical anomalies in the immediate proximity of the Cuango River.
Large alluvial diamond deposits were being mined downstream the river.
The company said in a statement to Rough&Polished that a third anomaly (MB04), estimated at 18 hectares based on its geophysical signature, had been field confirmed as a kimberlite.
Initially, a vertical core hole (LDH009-1) encountered sandstone at 4.3 meters before intersecting potential kimberlite from 8.2 to 9.8 meters, 15.8 to 48.5 meters and from 431.9 to 434.3 meters.
Sandstone was also intercepted below the last kimberlitic intersection to the end of hole at 594.7 meters.
It said a second inclined hole (LDH009-2) was underway and being drilled from the same location as LDH009-1 but was inclined at -50 degrees towards an azimuth of 318 degrees.
Sandstone had been intersected at a depth of 4.3 to 18.0 meters where interpreted kimberlite was intersected until 65.8 meters.
Core from hole LDH006m, which tested the 7 hectare MB02 anomaly was also being processed for diamonds and diamond indicator minerals, it said.
The company had been exploring the headwaters of the highly diamondiferous Cuango River with 50 kimberlites discovered to date.
