Nimba South

Nimba South


Project Location
The Nimba South Project is situated east of Ganta city in Nimba County, approximately 240km’s northeast of Monrovia. The area covers approximately 136km2 respectively. The main access from Monrovia to the property is via the Monrovia-Ganta Highway and then through the Ganta-Gban route. The Nimba-Buchanan rail corridor cuts through the property in the west. The property is traversed by the West African Power Pool (WAPP) and is accessible all year round.

Exploration Activity
Extensive exploration over the property commenced in February 2013 with geological field mapping in confirmation of aero-magnetic survey. Five Prospects were identified with the aid of mapping & geochem information. These included Whentein, Gbahn, BM-271, Dingamon-A and Dingamon-B Prospects. Geo-chemical assay results from float and outcrop samples sent to the SGS laboratory prompted the need for the excavation of 42 trenches over the identified iron ore anomalies. The 42 trenches were dug, mapped and sampled and revealed high grade iron mineralisation. To ascertain the resource potential of this anomaly, limited test drilling was necessary and a drill programme was planned with SRK.

34 drill holes totalling 3000m were drilled over the Gbahn and Whentein Prospects from November 2013 to February 2014.

The general lithologies intersected within these prospects were hematite-goethite iron formation, limonite, mica schist, amphibolite and granitic gneisses. Mica schist was only encountered within the Gbahn Prospect.

Local Geology
The Nimba South Project lies within the Liberian Age Province, the oldest of three geologic age provinces of Liberia. This province comprises of rocks of the Archean Age group which forms part of the West African Craton. During the period under review, fragments and boulders of recrystallized ironstone were identified in the target line of the Dingamon-Whentein prospect. Trenching activities over targets of these iron-rich float and boulders confirmed the presence of iron formations that underlie much of the basement complexes that are made of highly metamorphosed mafic and felsic rocks. Iron formation found in most parts of the target area consists of hematite-goethite that has an average grade of about 45% Fe.

The main host lithology for iron ore in the target areas is iron formation of a silicate facies. Assay results from trenching indicate that iron grades ranging from 20.5% to >60% Fe is localised southwest of the linearly-synformal structure that has been categorized as the Dingamo-Whentein prospect. This structure is an integral part of the southernmost extent of the Nimba Group of iron formations. The mineralisation extends over 17km’s along strike and is approximately 0.4km wide.

Geological logging of the drill cores from Whentein and Gbahn prospects revealed high potential for medium to high grade weathered ore within the first to 15m’s of all of the drilled holes within the Whentein prospect. 14 of the holes that were drilled in the Gbahn prospect showed unweathered mineralised material at 30 to 40m’s depth to the end of hole (“EOH”) in most of the holes drilled.

To adequately understand the full resource potential of the entire Dingamon-Whentein prospect, Cavalla Resources intends to embark on a follow-up exploration programme which would include further mapping of the prospect and test drilling focusing on the Dingamon area and the southernmost prospect of Wallah.

Work Program 2016/ 2017
The proposed work program 2016/ 2017 will focus on mapping with possible test drilling to further understand the resource potential.
