Project : Grand Kru
Grand Kru

The Grand Kru Dube project, located in the southeast corner of Liberia near the Cote d’Ivoire border, is crosscut SW/NE by the Dube Shear Zone and is highly prospective for gold mineralization.

Work to date has been comprised of a soil sampling program including 440 kilometres of line cutting and 8,475 soil samples, and a pitting program. (Total of 10,146 samples collected)

Of most interest to date is an area located near the Jolodah alluvial mine site where extensive alluvial activity has been conducted over an alluvial flood plain approximately 600 meters in length by 400 meters wide. Near the edge of the area local artisanal miners have dug a huge pit by means of shovel, rope and buckets approximately 30 metres in diameter by 15 metres deep to extract gold from a huge quartz vein they report contains much “visible gold” and which they claim to have reached during the time of the civil conflict.

Due to the heavy rain season which delayed work in reaching the quartz vein, Liberty geologists did not see the reported huge Jolodah quartz vein but two grab samples of quartz were randomly collected from what was considered refuse material from the large Jolodah pit. They were sent to the Eco Tech lab in Canada and returned assay values of 118.5 and 252 grams of gold per tonne (3.8 and 8.1 ounces of gold per metric ton respectively).

A third sample of highly brecciated transported quartz was collected from a nearby stream flowing into the alluvial flat which returned a value of 270 g/t Au or 8.7 ounces per metric tonne gold.

The Jolodah mine site area is near where Liberty geologists collected a stream sediment sample which graded 65.78 g/t gold during the initial 2005 reconnaissance program.

Geologically, the Dube Prospect is underlain by three main lithologies: namely, amphibolitic quartz diorite, greenstone schist and leucocratic gneiss. There are intrusives of banded iron formation (BIF) which form an iron - rich quartzite. The strike of these units is generally NE - SW and the amphibolitic quartz diorite dips 80 degrees to almost vertical. The leucocratic gneiss also dips on average 45 degrees while the greenstone schist dips 65 degrees to the east.

Structurally, the Dube Shear Zone runs through the central part of the property with some intersections of strong iron formation rocks. The trend of this shear zone is generally NE - SW.
Mineralization is generally associated with shearing and quartz stock works which normally occur at the contact between the intrusive mafic greenstone formation and the basement Archæan granite. It is also associated with the intensely sheared zones where there are significant carbonate and sericite alterations.

Liberty’s Dube exploration program commenced after the successful completion of the initial ground reconnaissance exercise. The 200m X 50m geochemical soil sample grid covers an area of over 120 square kilometers. More than 401km of grid lines were cut, traversed and soil sampled.

In addition, regolith mapping, detailed geological mapping and rock chip sampling was conducted concurrently with the geochemical soil sampling.

During 2009, a trench sampling program will be undertaken on the soil anomalies that occur in the southeastern, central and northwestern portions of the grid.

The Grand Kru Project is considered a highly potential region for the discovery of a significant deposit of gold.
