Metals of Africa identifies multiple U-IOCG targets

THE DRILL SERGEANT: Metals of Africa (ASX: MTA) has completed a program of geophysical modelling at the company’s 100 per cent-owned Mkindu project in Tanzania.

Metals of Africa picked up the Mkindu project in January this year as part of an acquisition of, what the company considers to be, a portfolio of five highly-prospective exploration assets.

According to the company, geological mapping data of the Mkindu area has confirmed the presence of volcanic filled breccia plug, brecciated sandstone, brecciated igneous rock and alteration of sandstone, which are all important geological criteria for IOCG style mineralisation.

The company recently had further geological modelling conducted by independent geophysicist, David Johnson of Zion Geophysics, which has identified multiple large scale uranium-iron-oxide-copper-gold (U-IOCG) drill targets.

MTA described the identified targets as appearing to be less than 100 metres below surface, predominantly concealed, and are of a substantial size in terms of depth extent and width.

The company indicated it now plans to conduct an initial exploration program including field mapping, surface sampling and ground geophysics.

This work is expected to be finished by about May, depending on how soon access to the site is permitted.

Once the initial part of the program has been completed, returning successful results, MTA anticipates following up with further drilling.
 
“The geophysical modelling involved 3D magnetic inversion processing on airborne magnetic data, flown at a line spacing of 250 metres, which identified multiple intrusions in an area believed to be conceptually prospective for Olympic Dam style U-IOCG style mineralisation,” Metals of Africa said in its ASX announcement.

“Olympic Dam is a multi-mineral ore body, it is the world’s largest known uranium deposit and also boasts considerable quantities of copper, gold, silver and rare earth elements.

“It is Australia’s largest underground mine.”

MTA indicated it would also be carrying out exploration activities at the company’s main Rio Mazoe project in Mozambique where a maiden drill program in 2013 intersected a number of high-grade lead-zinc mineralised zones at the Meque prospect.

Work at Rio Mazoe will recommence after the current wet season.
