The Gblita prospect is located in Gbarpolu County north of the Kpo Range and is highly prospective for a potential hard rock gold deposit.
In 2007 Liberty geologists collected four samples form quartz veins in the Lucky Hill (Gblita) area and one sample directly from a quartz veinlet. The samples were submitted to Eco-Tech Laboratories in Kamloops BC for assay analysis which returned the following assay values. (Liberty International NI 43-101 report September 2, 2007)

Liberty geologists collected three more grab samples from the same quartz system – several fragments of which contained visible gold – from approximately 30 meters distance from the original sampling point. The samples were again sent to the Eco-Tech laboratories in Canada and returned the following values.

Liberty geologists have since done extensive grids and geochemical work on the property including the collection of 7,187 soil samples.
The Gblita Prospect area is underlain by two broad basement lithologies, namely granite and granitic gneiss, into which quartz veins and veinlets have been intruded.
The general trend of both lithologies ranges between 44° - 82°, dipping steeply to the northwest (>65°). Around the Lucky Hill hard rock mine site, the area is underlain by greenstone and itabirite (banded iron formation) which forms the southern portion of the Kpo Range.
Field observations show that gold mineralization is controlled by the lithological contact between the granite and granitic gneiss. Veinlets of quartz, itabirite iron formation (BIF), ultramafic greenstone rocks, and amphibolites have been intruded into the granite and granitic gneisses.
The mafic greenstone belt is the main lithology which contains most of these potential anomalous zones. There are many undisturbed quartz veins which contain visible gold in the same areas where artisanal work is ongoing.
On the other hand, where the quartz veins are sheared, there are veinlets interbedded in the intensely sheared mafic schist. Most of these sheared mafic schists have been altered by hydrothermal fluids rich in carbonates and iron oxides. The carbonate-rich altered zones have elevated grades of gold throughout the Kpo Greenstone formation.
Since 2006, Liberty has completed a significant amount of geochemical soil sampling and detailed geological mapping work on the Gblita Prospect. A rock chip sample taken from the Lucky Hill hard rock mining site on the Kpo Greenstone formation returned an assay of 54g/t Au. In addition, two main anomalous soil zones have been delineated on this prospect from the geochemical soil sampling program which generated about 7,187 samples.
The initial sample grid was at 400m x 50m intervals and a subsequent infill grid was completed at 200m x 50m intervals over the two main anomalies.
A first phase pitting and trenching program, along with a possible airborne geophysical IP survey, is proposed for 2009.
