Project Overview

The Zolowo exploration licence covers an area of approximately 466 km2 in the Lofa County of north-western Liberia and is located roughly 25 km northeast of the Company’s Bella Yella gold project and 190 km northeast of the capital, Monrovia. It was selected based on a comprehensive in-house analysis of available datasets including geological maps, historic mineral occurrences, remote sensing data and satellite imagery. The licence is situated on the south-western portion of the West African Craton and contains 22 km of a significant 33 km long and 2.5 km wide NE-SW trending Archaean-aged greenstone belt which was historically mapped by the United States Geological Survey. In addition, numerous first and second order drainage systems that are closely associated with the greenstone belt have been extensively worked by artisanal miners with locals at some of the workings reportedly finding gold nuggets weighing up to 250 g and indicating that mining activity has been ongoing since the early-1930s.

Exploration Programme

An initial phase of reconnaissance exploration has been undertaken by the technical team involving prospecting across the licence, collecting rock-chip samples and mapping artisanal workings. Over 300 working sites, some up to a few hundred metres in length, have been identified along and parallel to the greenstone belt, a majority of which are either currently active of seasonally worked. They primarily target alluvial gravels and are found along multiple disparate first and second order drainage systems, most yielding coarse angular gold indicating the presence of multiple proximal sources along a strike length of approximately 17 km. In one NE-SW trending channel near Boyeame, active, seasonal and abandoned workings have been mapped semi-continuously along a length of roughly 1.5 km.

Amphibolites and felsic gneisses are common across the licence with mylonites and chloritized greenschists also being found within the greenstone belt. Minor blebs and disseminations of pyrite, arsenopyrite and, occasionally, pyrrhotite, are regularly observable. To date, numerous NE-SW trending quartz veins have been recorded with a rock-chip sample taken from a vein exposed in the base of a sizable colluvial working assaying at 2.95 g/t Au. In addition, prospective ‘smoky’ quartz has been documented both in-situ and float, particularly around the “Jerusalem” artisanal working where locals are reportedly able to find and crush blue-grey smoky quartz which exhibits visible gold mineralisation on the surface.

In order to identify and constrain the multiple source terrains that are responsible for the gold being mined from artisanal workings, the next phase of work will likely include a reconnaissance soil survey with samples being collected along a number of grid lines that encompass parts of the greenstone belt and its associated prospective outliers.
