    We Extract Precious Minerals.

  • INTRODUCTION

    Mining is the extraction of valuable geological materials from the earth and other astronomical objects. Mining is required to obtain most materials that cannot be grown through agricultural processes, or feasibly created artificially in a laboratory or factory. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone’s, chalk, dimension stone, rock salt potash, gravel
    and clay. The ore must be a rock or mineral that contains valuable constituent, can be extracted or mined and sold for profit. Mining in a wider sense includes extraction of any non-renewable resource such as petroleum, natural gas, or even water.

    LAKE VICTORIA GOLD FIELDS

    BUSOLWA/KABOHA PROJECT REPORT

    The Busolwa Project is a gold project located in the Lake Victoria Goldfields (“LVG”) region of northern Tanzania and forms part of the greater Busolwa licence portfolio.

    The Project is located approximately 75 km directly southwest of the city of Mwanza in northern Tanzania (approximately 160 km west-southwest by road) and ~20 km south of the town of Kasama. The towns of Geita and Katoro lie respectively 22 km to the west and 57 km to the westsouthwest. The figure below shows the location of the Busolwa Project within northern Tanzania. The Busolwa licence portfolio is located approximately 6 km to the south of Lake Victoria’s Mwanza Gulf. The Busolwa Project area lies approximately 12 km south of the Geita to Mwanza tarred road (Route B163) and exclusively comprises 13 licence. The eastern margin of the AngloGold Ashanti Geita Gold Mine holdings lies approximately 18 km to the northwest of the Project, as depicted in the figure below. Bulyanhulu Gold Mine, belonging to Acacia Mining PLC, lies approximately 35 km south of Busolwa

     

     

    MINERAL TENURE

    We hold the Busolwa licence portfolio through a number of wholly owned Primary mining licences (active and applications) making up the Project.

    GEOLOGY AND MINERALISATION

    Regional Geology

     

    The Busolwa licence portfolio properties are situated in the north-eastern sector of the Geita Greenstone Belt of the LVGF region of northern Tanzania (as depicted in the figure to follow).

     

    The area is characterised by mafic and felsic volcanic units of the Lower Nyanzian group, which is overlain by Upper Nyanzian ferruginous chert and felsic tuff. Equigranular granitoids and feldspar quartz porphyry intrusions cut the Nyanzian stratigraphy (Taylor, 2009). Most of Tanzania is

    underlain by the Tanzanian Craton, which is dominated by Archaean granites and greenstones, ranging from greenschist to lower amphibolite facies. The Archaean greenstones consist of mafic to felsic volcanic rocks and overlying immature basin sedimentary rocks of the Kavirondian

    Supergroup. Higher-grade metamorphic units (gneisses, schists, amphibolites, migmatites and quartzites) of the Dodoman Supergroup predate the granite-greenstones within the southern and south-western parts of the craton. Archaean (post granite-greenstone) granodiorites and tonalites make up the rest of the craton, particularly in the northern part.

     

    The LVGF occurs in a granite-greenstone terrain that extends from central Tanzania northward into southwest Kenya. It is bordered to the west by the Proterozoic Ubendian mobile belt and the east by the Neoproterozioc Mozambique mobile belt. The greenstone belts of the LVG are composed of rocks of the greenschist-facies Nyanzian Group. A succession of five units (Borg et. al., 1990) is recognised within the Nyanzian Group and is summarised (from oldest to youngest) from Shlüter (1997):-

     

    • Gabbro;

    • Basic volcanics composed chiefly of pillow lavas, locally banded iron formation (“BIF”) near the base;

    • Rhyolites of intermediate to acid character and sub-acid lavas with intercalated tuffs and agglomerates;

    • Greywackes with gritty andesitic tuffs near the top and BIF near the base; and

    • Slates and andesites with andesitic rocks near the top and BIF and tuffaceous silty and ferruginous slates at a lower level. The greenstone belts occur as lenses surrounded by granitoid rocks of the Dodoman Supergroup. The Nyanzian Group is unconformably overlain by the Archaean Kavirondian Group, which is composed of conglomerate, quartzite, argillite and pyroclastics. Proterozoic granitoids intrude the Kavirondian Group,

    and most predate major tectonic deformation.

     

    The Kasubuya, Ifugandi, Pamba and Lubando projects comprise the licence blocks alongside the Busolwa Licence Portfolio they occur to the east and west of the Busolwa Project respectively. The geology of these licence blocks is similar to that underlying Busolwa and hence they are prospective for similar styles of gold mineralisation.

     

    Local Geology

    Little outcrop is present on the Busolwa licence portfolio properties limiting the amount of bedrock mapping that may be conducted. The central part of the Busolwa licence portfolio is underlain by lower Nyanzian mafic volcanics (basalts) and rock of dioritic to gabbroic texture. Within the basalts are interflow tuffaceous to argillaceous sediments and intruding quartz feldspar porphyries. The northern part is covered by mbuga and sandy soils suggesting granitic nature of underlying bedrock. Some outcrops of coarse-grained granite occur in the western areas. Well foliated

    granodioritic granites occupy the southern portion and are cut by fine-grained (Potassium) K-rich aplogranite veins/dykes. White quartz veins are common in the area crosscutting granites and other rocks and in most cases are barren. Felsic and mafic volcanic units of the Lower Nyanzian

    stratigraphy constitute the lithologies of the licence areas. These are intruded by multiple phases of diorite and are crosscut by dolerite dykes. Young, post orogenic, granites, have intruded in the area and appear to circumscribe the Nyanzian lithologies in this area

     

    Project Geology

    The Mineral Resources reporting for the Busolwa licence portfolio occur exclusively within project, which encompasses the Busolwa Project. A Lower Nyanzian System mafic volcanic dominated suite, roughly 500 to 800 metres wide underlies the area, bounded to the south by fine grained,

    massive highly potassium feldspar rich foliated granite and to the north by tonalite. The tonalite is massive and occurs in contact with dolerite and basalt (interpretation based upon drillhole logs). This consists of 40% medium grained plagioclase + <25% quartz + 30% pyroxene + 5% biotite.

    The greenstones strike approximately northwest to southeast to west-northwest to east-southeast towards the eastern end with a flexure (also possibly a fault). Dip is interpreted to occur towards the northeast. This unit underlies the main target area making up the Project. This unit can be further subdivided into two distinct parallel horizons that are intruded by mafic dykes parallel to stratigraphy. The basalt in contact with the granite in the southern area of the Project is intercalated with siltstone, tuff, and argillite and is intruded by quartz feldspar porphyry (“QFP”) dykes. Pyrrhotite is mostly associated within strongly foliated mafic volcanics while pyrite occurs predominantly within the QFP. Approximately 200m north of the granite the basalt interflow sediments and felsic dykes become rare. The mineralized zone appears to consist of up to four sub-parallel shears or shear zones which dip to the northeast at approximately 75°and strike northwest to southeast.

     

    MINERALIZATION

    The Busolwa project (prospecting licence149/ 94) is located in the southeastern part of the Geita Greenstone Belt, 40 km from Geita town. Access is via the main Mwanza - Geita road to Kasamwa, then a south turn off road for 20 km and continues past Kaboha to Busolwa village. The geology of the property consists of lower Nyanzian basalts with interflow sediments including black argillites, upper Nyanzian sequence BIF-chert, greywacke, felsic sediments and other volcaniclastic sediments. Gabbroic to dioritic intrusions outcrop locally. Granitoids occur in the south and northwest part of the property. Exploration work in the area started during the colonial period (1930”s) in which loam sampling and trenching was carried out and first gold showing documented. JCI conductedsoil sampling, trenching and Reverse Circulation drilling program in prospecting license 149/ 94 (Busolwa) in 1998.Significant trench results were; BST-1 5m @12.2 g/t Au, BST-3, 3m @ 1.8g/t Au and BST-4 4m @4.7 g/t Au. The drilling was focused on the Nyamashiki hill target identified by structural interpretation of airborne magnetic combined with geological mapping, soil geochemical sampling and positive results from the trenches. Significant RC drilling results included 0.50m @ 70.5 g/t/ Au in quartz vein BIF, 13m @ 3.24 g/t Au, 5m @ 1.69 g/t Au, 2m @1.89 g/t Au, 1m @ 9.79 g/t Au, 5m @ 1.28 g/t Au and 12m @ 2.72 g/t Au. In 2000, BEAL carried out soil and rock sampling, geological and regolith mapping over the entire property. Two NW-SE trending soil anomalies 3km long were delineated north and south of the BIF ridge. In June 2001, BEAL contracted Fugro Ground Geophysics to carry out a time domain IP survey using 50 m dipole spacing with a spread of n=1 to 6 over 10 lines covering approximately 24 line - km. The IP survey registered several high chargeability anomalies coincident with the anomalous soil trends. A first phase of RAB drilling was carried out mainly in the northern part of the BIF ridge as follow up of positive JCI RC drilling, BEAL soil (Fig. 2) and IP results. Significant results from this program included 0.98/ g/t/ Au/ 7 m including (1.75/ g/t/ Au/1 m) from quartz vein in tuffaceous sediments close to shear zone in the northern target. More than 1.5 km of weakly mineralized zone was outlined in the north target area. One fence drilled in the southern target (south of the BIF ridge) had one significant intersection 0.73/ g/t/ Au/ 3 m including 7.7/ g/t/

    Au/ 1m. A second phase of RAB drilling was conducted to test the southern target defined by a 3.5 km long NNW trending soil anomaly, coincident with IP anomalies and the Upper-Lower Nyanzian contact. In addition the program tested the possible strike continuity of the significant intersection (0.73/ g/t/ Au/ 3m incl. 7.7/ g/t/ Au/1 m). The results from this phase indicated discontinuous (erratic) weak mineralization associated with quartz veins hosted in mafic volcanics. The most significant results included 0.25 g/t Au / 6m (including 0.38 g/t Au / 3 m) and 1.87 g/t Au / 6 m (including 2.71 g/t Au / 3 m) all from one drill hole; however these results could not be traced along strike. In conclusion, the exploration work that has been carried out at Busolwa has indicated that the southern target has little chance of finding a large deposit. The northern target with anomalous to significant trench,RAB and RC results seems to be the most prospective corridor worthy follow up work. The BEAL RAB results seem to have picked weak signature along the possible NW strike continuity of the Nyamishiki hill JCI target. Other possible sub-parallel mineralized trends have as well been picked north of this target. It is therefore recommended that future exploration program should include RAB infill at about 200m spacing to trace possible strike continuity of the Nyamishiki target and other possible sub-parallel mineralized zones of limited strike length. RC drilling to probe depth continuity of the Nyamishiki target and as well as any other positive results from the RAB drilling should follow the RAB drilling

     

    RECOMMENDATIONS

    The following recommendations with respect to the Mineral Deposit of Busolwa:-

    • Excellent potential for a significant Gold recovery and mining

    • Additional drilling is required both for infill for Mineral Resource definiton purposes, as well as for lateral and depth extensions. This drilling should be mainly RAB and RC drilling so that more geological information can be gathered to improve confidence in the geological and resource model interpretation within the project area;

    Mining and Processing Minerals

    Actual mining can begin once construction of a mine is complete. Miners use drills and explosives to break up the rock and large scoops and machines to move the rock to the processing plant. Mined rock contains valuable minerals as well as worthless ones, all mixed together. Processing separates out the valuable minerals from the waste. Usually, the rock is first crushed into a fine powder. Then, a separation process captures the small amount of valuable minerals from the large amount of powdered waste rock. Some minerals are then refined to produce pure metal in a process called smelting.

    A mining company has to deal with the leftover waste materials, called tailings, which are rock fragments, dust, and chemicals. They must be stored in safe areas to avoid polluting the air or water.
