Project :: Mafic
^{Gold
Nimba South}

The Mafic Prospect lies in the southwestern portion of the Nimba South Project and approximately 10 km southwest and on strike with the Kuobhan Mountain prospect

Geologically, this prospect comprises rocks that have been intensely sheared and have been subjected to a series of tectonic activity such as faulting and folding. Most of these faults strike NW-SE and have been confirmed by field geological mapping.

Rigorous field geological mapping by Liberty geologists conducted over the prospect has identified intensely sheared intrusive amphibolitic greenstone facies in contact with basement Archæan granites. A series of diorites intrusive into the granites have also been identified and mapped.

Structurally, there are significant amounts of later faulting which have affected this area. NE-SW and E-W faulting has occurred on the Mafic.

Elevated gold values have been found to be associated with the fluid movement along the highly faulted units and also with the chlorite and carbonate alterations within the mafic schist greenstone formation.

Two phases of geochemical soil sampling programs, including a regional program on a 400m x 50m grid and an infill program at 200m x 50m, have been conducted over the entire prospect. Anomalous soil geochemical targets have been identified mainly along the fault zones and the greenstone belt further south. To date, 11 test pits and a trenching program to understand the stratigraphy and also to test possible mineralization at the near surface have been completed.

Due to the presence of active alluvial miners in the area, a hard rock gold source is believed to potentially exist within the prospect.

However, results to date have not located it due to possible overburden masking.

Consequently, a ground geophysical IP program (pole-dipole) is recommended over the Mafic Prospect.

Based upon any geophysical anomalies that may be detected, structure and favorable geology, a follow-up RAB (rotary air blast) drill program will be proposed. The RAB drilling will be able to help investigate any subsurface geophysical anomalies that are hidden or masked by overburden.

Fieldwork statistics to date are depicted in the table below.
