FORECASTING PROSPECTIVE AREA

Within the licensed area of MAGNUM LINK (SL) LIMITED, the result of decoding and analysis of geomorphological and neotectonic conditions outlined fifteen (15) prospective areas for fundamental mineralization (see Figure 11). Main criteria for predicting fundamental sources are, firstly;


Prospectivity of the outlined areas may be determined by means of heavy mineral concentrate sampling the key points being favourable for ore concentration. These points are outlined on the basis of analyzing planned and profiled features of fluvial flows draining the outlined areas.

Area OP01 is located in the southern segment of the central part of the license, upstream is found the Mabokotona and the Makoungi basins. It is localized in the crossing point of the presumable radial rift R202 with fault morphological structure and concentric rift K03 with thrusting morphological structure, almost unclear in the present segment. The area is complicated by the 3rd order lineaments which accompanies allegedly the rifts of the lower order. In its northern part, the prospective area surrounds the small circular structure which probably projects small granite intrusive body detached among massive minerals. In surface structure, it is inclined to hollows in water-dividing area with prevailing slope steepness of 8-150 meters in the view of prevailing heights of nearly 430-460 meters. Fall shift is incremental up to middle intensity. In multispectral images showing natural colors, this area is shown by the dark-grey phototone (graduating into brown-grey) contrasted with prevailing rust-pink shades. The presence of green stripes probably corresponds to flora within the fluvial flow formation.

Area OP02 is located in the north-eastern part of the license, along the right slope of the Matiri river. Here the stream bed is controlled by the radial rift R101 (probably gapping morphological structure) between circular elements K01 and K02 (probably thrusting morphological structure). In surface structure, it corresponds to the low-split slope of the abovementioned river with prevailing slope steepness of 15-400 meters in the view of prevailing heights of nearly 420-440 meters. Fall shift has mainly middle intensity and the multispectral images in natural colors of this area is shown by the dark-grey phototone (graduating into black) contrasted with prevailing pink shades in the locations of presumable bedding rock output. Presence of green probably corresponds to flora within the valley slope.

Area OP03 is located in the central part of the northern border of the license area, mainly the upstream of the basin of the 2ndorder left tributary of the Makuranko river. It is localized in the adjacent area of the 3rd order radial lineament which probably corresponds to the fault morphology rift (north-western fall) to the 1st order sub latitudinal lineament LS01 with indefinite morphology. The eastern boundary is controlled by the 3rd order arc lineament which corresponds probably to the fault deformation of the west-north-western fall. In surface structure, it corresponds to concentric slope in water-dividing area with slope steepness of 8- 400 meters in the view of prevailing heights of nearly 390-420 meters. Fall shift is incremental with middle intensity in equal proportions. Multispectral images in natural colors depicts that, this area is dark-grey phototone (up to black) contrasted with pink and rust-pink shades in the locations of presumable bedding rock output. Presence of green probably corresponds to flora within the fluvial flow formation.

Area OP04 is located in the central part of the northern segment of the license boundary, mainly upstream the basin of the 2ndorder left side stream of the Makuranko. It is localized by the 3rd order arc lineaments which allegedly correspond to new fault-like deformations of the north-western fall. The area is influenced by the circular lineament K03 at the flanges of which the abovementioned deformations are developed. In surface structure, it corresponds to concentric slope in water-dividing area with slope steepness of 15-400 meters in the view of prevailing heights of nearly 430-450 meters. Fall shift is incremental with middle intensity in equal proportions. In the multispectral images in natural colors this area is shown by the dark-grey phototone (up to black) contrasted with pink and rust-pink shades in the locations of presumable bedding rock output to the south-east of the upper limb. Presence of green probably corresponds to flora developed within lower limbs and fluvial sources being created here.

Here, the stream bed is controlled by the radial rift R201 (probably gapping morphological structure), to the south-east from its crossing point with the concentric element K01 (probably thrusting morphological structure) depicted unclearly. In surface structure it corresponds to the low-split slope of the abovementioned river with prevailing slope steepness of 15-400 meters in the view of prevailing heights of nearly 410-440 meters. In the multispectral images in natural colors, this area is shown by the dark-grey phototone (near black) contrasted with pink and rust-pink shades in the locations of presumable bedding rock output. Presence of green probably corresponds to flora on the slope.

Area OP06 is located in the north-eastern part of the study area, closely to the area OP02. It goes along the right slope of the Matiri, in its water-dividing area with the Gbonkobon. Here, the stream bed is controlled by the radial rift R101 (probably gapping morphological structure) but the area is inclined to the circular element K01 (probably thrusting morphological structure) with converted landscape due to creation of rift-like areas to the north and to the east influenced by the regional rift L103. In surface structure, it corresponds to the low-split slope of the abovementioned river with prevailing slope steepness of 15-400 meters, lesser 8-150 meters and lower, in the view of prevailing heights of nearly 310-340 meters. Fall shift is incremental in water-dividing area and has middle intensity near the stream bed. In the multispectral images in natural colors, this area is shown by the dark-grey phototone with green shades which probably correspond to flora on the slope.

Area OP07 is located in the central part of the northern boundary of the research territory, in the western slope of the Makuranko, up to its water-dividing area, to the east from the 2nd order left side stream. It is localized by the lower limb of the 3rd order radial lineament which probably corresponds to the rift of fault-like morphology of the north-western fall. It is controlled by crossing points with concentric lineaments K01 and K02. In surface structure, it corresponds to the middle-split slope with slope steepness of 3-80 meters, 8-150 meters and prevailing steepness of 15-400 meters in the view of prevailing heights of nearly 440- 480 meters.

In surface structure, it is controlled by the upstream of the Makoungi valley with slope steepness of 8-150 meters and 15-400 meters in equal proportions in the view of prevailing heights of nearly 440-460 meters. Fall shift is incremental up to middle intensity. In the multispectral images in natural colors this area is shown by the dark-grey phototone (up to brown-grey) contrasted with rust-pink shades. Presence of green probably corresponds to flora in the river valley.

Area OP09 located in the southern part of the project area, mainly in the upstream of the Makurango river left tributary. It is localized by the 3rd order arc elements which allegedly correspond to new fault-like deformations of northern and north-western fall. Here arc elements create the crossing point with fault-like sub meridional zone of eastern fall projected by lineaments L201 and L203. In surface structure, it corresponds to the concentric slope in water-dividing area with prevailing slope steepness of 15-400 meters in the view of prevailing heights of nearly 380-400 meters. In the multispectral images in natural colors, this area is shown by the dark-grey phototone contrasted with pink shades in the locations of presumable bedding rock output to the south of the upper limb. Presence of green probably corresponds to flora developed within lower limbs and fluvial sources being created here.

Area OP10 is located in the southern part of the project area, mainly in the upstream of the Mabokotona river, in the 2nd order left slope of its left tributary. It is localized in the sub latitudinal lineament zone accompanying the 2nd order element LS032 which probably project ridge-like structure of similar course. Here, the area is complicated with the 2nd order sub meridional lineament and the adjacent 3rd order lineament (towards north-east) which allegedly correspond to the north-western fault. In surface structure, it corresponds to the north-western slope with the adjacent water-dividing saddle and slopes in 8-400 meters in the view of prevailing heights of nearly 400-420 meters. The prevailing fall shift is incremental up to middle intensity in the western part. In the multispectral images in natural colors this area is shown by the dark-grey phototone (up to brown-grey) contrasted with rust-pink shades in the locations of presumable bedding rock output to the south-east of the area.

Area OP11 is located in the south-western part of the license boundary, in the left slope upstream of the Mabokotona rights tributary. It is localized in the western part of the adjacent point of branch 3rd order lineaments (towards west-north-west, indefinite morphological structure) to the presumable 2nd order sub meridional rift L201. In the eastern part the prospective area adjoins to the small circular structure which probably projects small granite intrusive body detached among massive minerals. In surface structure it corresponds to the concentric slope of the abovementioned stream with prevailing slope steepness of 15-400 meters in the view of prevailing heights of nearly 415-425 meters. This area is shown by the dark-grey phototone (up to brown-grey) contrasted with prevailing pink shades to the east. Presence of green probably corresponds to flora on the slope.

Area OP12 is located at the southern border of the license area, in the water-dividing area of the left slope of the Mabokotona. It is localized in the western part of the adjacent area to the presumable 2nd order sub latitudinal rift LS03 (circular structure) positively positioned in the surface which probably projects the concentric intrusive granite body detached among massive minerals. In surface structure it corresponds to the concentric slope of the above mentioned river with slope steepness of 15-400 meters in western and eastern flanges and 8-150 in central part in the view of prevailing heights of nearly 435-445 meters. Fall shift is incremental without clear extreme points. In the multispectral images in natural colors this area is shown by the grey phototone (up to brown-grey) contrasted with prevailing pink shades to the south-east. Presence of green probably corresponds to flora on the slope.

Area OP14 is located in the western part of the southern segment of the project area, in the water-dividing area of the eastern slope of the Mabokotona. It is localized to the north from crossing point of the regional lineament L102 (towards north-west) with the presumable 2nd order sub meridional rift L202. In surface structure, it corresponds to the linear coarse slope of the abovementioned river with slope steepness of 15-400 meters in the view of prevailing heights of nearly 250-360 meters. Fall shift is incremental in northern and southern parts and moderate contrastive in central part. In the multispectral images in natural colors, this area is shown by the brown-grey phototone with deep enough green shades which probably correspond to flora on the slope.

Area OP15 is located in the north-western part of the license area. Its north-eastern segment is located upstream the southern tributary of the Makuranko and the rest part of this unit is located in the water-dividing area of the eastern slope of the Mabokotona (north-western aspect). It is controlled by the sub latitudinal lineament LS01, to the east from its crossing the presumable 1st order regional rift L102. In surface structure it corresponds to two slope flanges of detached elementary basins with slope steepness from 8-150 meters to 15-400 meters in equal parts in the view of prevailing heights of nearly 360 meters. Fall shift is mainly incremental, up to moderate contrastive. This area is shown by the brown-grey phototone contrasted with prevailing pink shades to the south east, with deep enough green shades which probably correspond to flora on the slope.

In addition to the prospective areas above, there are also nine (9) areas with possible kimberlite pipe location (see Figure: 11). The main criteria of area localization were to use the analogy method. In particular, kimberlite field development in surface depression which correspond allegedly to rift-like structure. Productive fields in local depressions are often inclined to crossing points of radial and circular elements of centralized concentric structures. The license area is located in the south-western part of such structure. So in outlining the areas of presumable kimberlite field development, these were considered local rift-like depressions being typical of crossing points of radial and concentric lineaments. Also the areas located along the 1st order regional lineament L102 were localized as prospective ones. Within the latter one, they were created by the rift-like depression system on the similar surface. Compulsory condition for localization is also the presence of accumulated circular elements in multispectral space images which are featured by changing green and pink colors by grey and dark-grey spectra. Diameter of similar circular structures makes up 100-500 meters with their accumulation areas not exceeding 3 km2.

Most of the areas of probable kimberlite field development are located along two 2nd order radial lineaments, i.e. fields DP05 – DP09. Field DP09 is located much to the east from the radial rift R101, along the concentric lineament К03, towards the 1storder lineament L103, and is inclined to the 3rd order circular structure adjacent to the lineament К03 from the south.

Field DP01 is located in the north-western part of the licensed area. It is controlled by the 1st order regional rift L102 accompanied by several 3rd order drifts with different morphological structures.

Field DP02 is located in the crossing point of 2nd order sub latitudinal and sub meridional drifts which also control fluvial network development in this area and is complicated by the smaller 3rd order lineaments with the corresponding morphological structure. These rifts also control the contrasting rift-like depression which evidences seismic activity in this area.

Probable fields DP03 – DP04 are controlled by the radial lineament R202, starting from its contact with concentric lineament K03. They are located on the left slope of the Mabokotona upstream, in the bottom of the rift-like structure towards the south-west, between the lineaments which correspond to fault-like rifts R202 and R203.

Moreover, outlined modern fluvial network areas being favourable for concentration of valuable elements in the modern alluvial deposits (see Figure 14). In predicting location of deposits, the main criteria are both planned and profiled extreme points in the valleys of the fluvial network. The presumable deposit points in the modern alluvium are outlined within the fluvial flows, starting from the 2nd order (by Strahler). Favourable river areas in these places are located downstream, with the stream bed extreme points, both been planned and profiled.

Points 02, 03, 04, 06, 08, 10 are subject to ground truthing. The presence of valuable elements in the abovementioned points will give full image of prospectivity of the area due to the fact that almost all destruction of the solid fundamental material shall be controlled by these points. Other points shall be tested given the positive results in the abovementioned points located downstream. Given the positive result on containing valuable elements it is recommended to perform additional geomorphological investigation in order to position all the areas favourable for creating deposits upstream in the productive stream bed.
