INTRODUCTION
This report presents an exploration work carried out by Tangeray Resources Zambia Ltd over the Mufumbwe Licence area (17797-HQ-LPL). It is situated in Mufumbwe districts of Western Province of Zambia. The Mufumbwe licence covers approximately an area of 1126.67 hectares and Tangeray Resources Zambia Ltd holds the mineral and exploration rights of the tenement area for the purposes of identifying an economic base metal resource. The map on figure 1. below shows the locality and extent of the Mufumbwe Licence.
LOCATION AND INFRASTRUCTURE
The licence area is 100 km north of Kaoma and along Kaoma- Kasempa Road. It is in Mumfumbwe district. The licence can only be accessed through D301.During the wet season the access to the area becomes difficult and exploration is pretty slow due to the water logged main gravel road and other tracks. The activities of the inhabitants in the area are subsistence farming, hunting, charcoal and burning.
Figure 1. Topographical location of the licence area
The area is not connected to the National Grid. Local inhabitants use charcoal and wood for cooking, candles or kerosene lanterns for lighting at night. Hospitality

industry such as hotels, lodges, guest houses etc. is non-existent.
Government schools and clinics are only found along the Kaoma-Kasempa Road. Most merchandise materials are bought from Kaoma and transported to make shift shops transported in open van and bicycles. Houses for local inhabitants are mostly made of bricks constructed from clay. Roofs of huts are usually made of grass and iron sheets in exceptional circumstances. Population is very sparse.

SOIL AND VEGETATION
The variation in soil differences is largely attributed to the geomorphology and underlying rock types. Generally the area is dominated by sandy cover mostly whitish brownish to orange soils in areas with lateritic and fericrite surfaces. Some dambos and dambo margins are of white to white-grey clay to silt soils derived from mainly deposition from the surrounding areas.
Mufumbwe licence area is mostly covered with savannah style of forest. The landscape has an open broadleaved deciduous tree popularly known as the Miombo tree within the soils derived from Kalahari sedimentary rocks. The land area is lightly cultivated with only a few local people owning smaller portions of the land where they cultivate their crops.
Most of the natural vegetation is still intact and in its natural state. Water bodies such as dambos are characterized by scanty bushes and tall grass. Some dambos are perennial whereas others are dry during the dry season. Thick vegetation is characterized by short grass whereas open lands are characterized by tall grass.
TOPOGRAPHY AND CLIMATE
The topographic expression of Mufumbwe area is generally flat with low altitude regions along rivers and stream. Generally the major part of Mufumbwe is a plateau with miombo woodlands vegetation. The general height of the area ranges from 1,150 to about 1,250 metres above sea level or slightly higher. Most of the area is gently undulating. Mufumbwe has a humid climate and is classified as subtropical (dry winter and hot-wet summer), with a subtropical moist forest bio-zone. The seasons are divided into three main periods, namely; the rain season (middle November to April), Cold season (April to August) which becomes increasing windy towards August. Hot season begins from September to end November. The hot season is progressively hotter towards October. The rains are heaviest from January to the end of March.

GEOLOGY
Mufumbwe licence (17797-HQ-LPL) lies within the Katangan high Region of the Lufilian Fold Belt. The Katangan high Region is comprised of Katangan Supergroup rocks, which consists of two dominant member groups namely, the upper and lower Kundelungu. In this region the Kundelungu is known to have been covered by younger sequences higher up in the stratigraphy namely the Kalahari and the Karoo. In a few localities the young sequences higher up in the stratigraphy namely Karoo and Kalahari have been eroded and are represented by a thin horizon of the carbonaceous shales which marks the contact between the Karoo and the upper Kundelungu. The areas to the North east of the Mufumbwe project exhibits formations with hydrothermal hematite and magnetite associated with copper mineralization, the area also exhibits progressive hydrothermal alteration and brecciation, significant disseminated copper carbonate associated with hematite and magnetite are evident in upper parts of Kundelungu sequence in these localities. The Kundelungu consists of regionally of thinly interbedded argillite with thin beds of calcareous sandstone and siltstone. The geological structure of the Kantangan high within the Mufumbwe area consists of meta-sediments including massive hematite alteration which is difficult to recognize from altered parent rocks.
The Mufumbwe licence area has three stratigraphical units on the surface, namely Kundelungu, granite and Kalahari.

WORK DONE During the period of the first quarter of 2014, Tangeray Resources Zambia Ltd completed to reconnaissance mapping and sampling trips to the 17797-HQ-LPL area. Rock chip samples from the sound field visit were collected from old mine dumps and outcrops within the SPP area and the surrounding environs. All the samples were malachite+/- other copper oxide minerals. Although the samples that were collected, sending to the laboratory did not become a priority and consequently assay are pending. Mineralization Secondary copper mineralization is confined to the breccia zone and in the fracture zones or joint planes of the shales. The ores include: malachite (as the main ore), chrysocolla and azurite. Accessory minerals are quartz, chlorite and hematite.

PROJECT VISION AND OBJECTIVE
The decision to acquire mining right in the area was made, in addition to other economic reasons, to encourage a systematic and organized copper exploitation venture. As such the
9
overall objective is to avoid wasteful mining practices, both environmentally and economically. The local communities, who are mostly involved in illegal and disorganized mining activities, will be incorporated into the mining venture, thereby providing employment and other socio-economic benefit to them. This is in line with the national vision to alleviate poverty through sustainable natural resource utilization. Further, the socio-economic vision for the mining operation can be summarized as follows: - To discourage illegal mining (for the sake of national benefit through tax from copper
exports) - To generate employment opportunities - To discourage wasteful mining practices, environmentally and economically - To contribute to poverty alleviation It is based on the above that capital investment is being sought, for the mine to attain meaningful profit levels and hence fulfill the intended socio-economic objectives of contributing to the uplifting of the standards of living for the Zambian people. To increase the production to profitable tonnage margins, the company needs to invest in capital equipment and other resources essential for a successful mining operation.
PROJECT IMPLEMENTATION
The directors have initiated this project with a view to gain experience in experience in mining activities, through operations in the area. Open excavations and pits will be opened and commissioned using hired machinery and hand tools. Local labourers will be used with direct supervision from the directors. The company would like to improve production levels and operation modes by acquiring efficient mining machinery and tools, and engaging expert consultants in mineral resources development.
SOCIO-ECONOMIC AND ENVIRONMENTAL CONSIDERATIONS
Tangeray Resources Zambia Ltd is operating a Large-scale prospecting in rural Mufumbwe area of North-western Province. The landscape is flat. Further, the company will operate in an environment friendly manner. Workers will be sensitized on the need to practice safe environmental and human health working modes. ZAMBIA AND COPPER Zambia produces a good amount of copper and cobalt plus uranium and gold. The world copper trade is never complete without the Zambian input. It is anticipated that systematic and organized exploitation of the copper deposits will be promoted and supported by various stakeholders. If properly explored and systematically mined, the copper mine could contribute to Zambia’s GDP. Systematic exploration utilizing modern methods and detailed mapping, and investment support in form of loans, offers considerable potential for the discovery of additional deposits of copper.
10
CONCLUSIONS
The copper-gold-cobalt deposits are in rural Mufumbwe District.
The mining of copper ore will be environmentally friendly and the environmental management plan will be drawn later.
The character of the site will be preserved
No agricultural activities are seen for several kilometres around the sites
Tangeray Resources Zambia Ltd will do business with Zambian companies.
Tangeray Resources Zambia Ltd will only employee Zambians.

LOCATION AND ACCESS
The project area is in Liteta of Central Province of Zambia. Access to the area
is through the Great North Road. The site is located on the topographic map of
Zambia at scale 1: 250,000. The Latitude - Longitude coordinates outlining the
area of interest are as shown below.

The area is 139.50 square kilometers.
Historically, the area has been a prospective area for copper and gold mineralization
as far back as from 1950s. Various international prospectors have traversed the area in
search of mineral deposits. This is evidence by several prospect markings, old bore
holes and archived records at Kalulushi Chamber of Mines in the Copperbelt and the
3
Geological Survey Department in Lusaka. As such, most of the local people are aware
of the potential of mineral wealth in the area. This has prompted most of the local
people to engage in illegal mining activities for several years, following up old
prospect beacons.
Regional Structure
Regional Geology
The geology of the Liteta is composed of quartzites and schists of the Plateau Series
belonging to the Luano Valley, which is part of the craton that has remained stable
during the orogenic deformations probably since Archean. In general the area is
overlain by a thick sequence of quartzites and pelites of the Plateau Series
unconformably overlying the older volcanics and granites. Krishna et al (19--)
observed that the gold occurrences in the valley in general are confined to the
conglomerates of the Plateau Series and it’s peripheral with the Basement rocks.
Krishna et al (19--) concluded that the alluvial gold occurrences along Mulembo,
Milambo, and Msekesha streams warrant further investigations for small-scale
exploitation. Speed (1984) also observed that; a) the sediments are consistently
enriched in gold relative to other world sandstones; b) that the depositional
environment was suitable for heavy mineral concentrations. The conglomerates and
sandstones in braided river system are similar to that of Witwatersrand though the
latter are more mature and the source is greenstone belt; c) gold content correlates
well with some of the sedimentary features to suggest that the mineralization is of
4
paleoplacer origin. Speed (1984) also observed that if the analogue with
Witwatersrand is valid then only occasional 50-100cm interval in a 1000-2000m
sequence may be enriched to economic level.
Local Geology
The deposits are broadly strata-bound and are hosted by a series of NE striking
calcareous conglomerates, siltstones and ironstone horizons of the Kundelungu Group.
Surface exposures of gossans stained with malachite are quite prevalent in the area.
The mineralisation zone is quite extensive though the depth of mineralisation varies as
one traverses from site to site. In general, the ore zone is transgressive to the
stratigraphic host sequence.
The prospect area is characterised by some of the following features:
(a) deep dissection by erosion into gullies and craggy landforms
(b) abundant outcrops
(c) silicified grey to tan in coloured shales and siltstones
The secondary mineralisation consists of plugs of malachite and subordinate azurite.
The average depth of excavations made in the area is 2m.
3.2 Gold Reserve estimation
Native gold has a high density (19gm/cm3), and is chemically resistant to weathering.
Therefore it can be transported in large distances by water and can be preferentially
concentrated in suitable hydrodynamic conditions. Such concentrations are called
placer deposits and can occur within fluvial or coastal of a gold placer deposit are:
1. A gold – bearing source
2. Erosion of this source
3. Transport of detritus from the source by water, and suitable hydrodynamic
conditions for the concentration of gold.
The reserves for the eastern part of gold prospect are estimated at 240 000t of gravel
at 3.5g/t gold. The mine life is expected to be 6 years at the rate of 30 000
tonnes/annum. A large-scale mining licence covering an area bound by Latitudes
14o 44’ 12”S and 14o55’ 06”S and longitudes 28o59’ 54”E and 30o08’ 30”E is
recommended by way of panning.

Area 68.8920 Km Sq
Minerals Copper, gold and cobalt. Drainage The area is drained by the Luhanzhila River from east to west and Kanukalo, Chijempakema and Chimiolo streams north soutwards. Regional Structure The country west of the Copperbelt in the NW Province is underlain by a series of domes. The eastern domes (the Luswishi and Solwezi domes), have an oval .outline whereas the western domes are more
4
elongated and orientated SW-NE. This is parallel to the regional structural trend which is characteristic of the western part of the Lufilian Arc. There are three western domes, the Mwombezhi and the Kabompo with the third being a poorly exposed, possible SW extension of the Kabompo dome. Some controversy exists over the formation of the domes which may have been the result of simple uplift along axes parallel to the Lufilian Arc, or have been created by NE thrusting and ramping during the Lufilian Orogeny (Coward and Daly, 1984). The Lufilian Orogeny, (840-465 Ma), was a multiple event which comprises at least three phases of folding. This complex folding has resulted in smaller structural basins and domes being formed within the regional domes structures by later episodes of cross-folding about a N to NW axes (Appleton, 1978). South of the Kabompo and Mwombezhi domes, the effects of the Lufilian Orogeny decrease although locally intense folding is still found within the Katanga lithologies. Faulting in the area of the licence areas is most obvious in the vicinity of the domes. The faults are orientated either NE (parallel to the domes), or NW. Graben structures are a major feature of the area (Kabompo Gorge). These post-Lufilian faults are less conspicuous further S. Where faults cross the Katanga succession they are represented by fault breccias which in places appear to have had a polyphase formation with several episodes of movement with recementation of the fault breccia by migrating solutions after each phase of movement (Klinck, 1977). Metamorphism The highest metamorphic grades in the NW Province occur in the dome areas. The grade progressively decreases away from the domes and in a southerly direction (Ridgeway and Ramsay, 1986). The inner zone of amphibolite-grade passes outward through an epidote-amphibolite metamorphic-facies to a greenschist-facies zone. The northern part of the Mwombezhi licence area falls within the epidote-amphibolite facies along the southern edge of the amphibolite core. The northern part of licence area is underlain by greenschist facies whilst the southern part is underlain by unmetamorphosed Kalahari Group LOCAL GEOLOGY The deposits are broadly strata-bound and are hosted by a series of NE striking calcareous conglomerates, siltstones and ironstone horizons of the Kundelungu Group. Surface exposures of gossans stained with malachite are quite prevalent in the area. The mineralisation zone is quite extensive though the depth of mineralisation varies as one traverses from site to site. In general, the ore zone is transgressive to the stratigraphic host sequence. The prospect area is characterised by some of the following features: (a) deep dissection by erosion into gullies and craggy landforms (b) abundant outcrops (c) silicified grey to tan in coloured shales and siltstones The secondary mineralisation consists of plugs of malachite and subordinate azurite. The average depth of excavations made in the area is 2m. Several types of alteration have been mapped as being silicification, chloritisation and sericitisation. Wall rock alteration is pervasive, consisting of argillitisation (kaolinitisation), carbonatisation, silicification and minor chloritisation. These are important guides to mineralisation and would be important in order to locate the primary sulphide mineralisation. Late stage veining consisting of calcite, hematite, and siderite is common. Structure The Cu ore bodies are in a fault block in a well-faulted terrain, and it follows a bedding contact, which has been locally displaced. This structure is well-delineated using magnetic surveys and is an important link to mineralisation as these acted as pathways for mineralisation. Thrust faulting is an important structure in
5
the area and the several units or scales separated by faults, i.e. block of fairly dipping shales, bounded on 2 sides by faults, beyond which the structural trends may be quite different. The general regional strike trends appears to be NE – SW.
Summary – Geology, Mineralisation and Exploration The deposits are broadly stratabound and are hosted by a series of NE striking. N-W dipping (76°) calcareous conglomerates, siltstones and a limestone horizon of the Kundelungu Group. An adjacent caclastic calcareous fault breccia zone contains mineralised clasts but appears to be post-mineralisation age. In detail, the ore zone is transgressive to the stratigraphic host sequence and dips steep (73° NW) with a steep plunge to the NE (72°). The primary mineralisation is epigenetic, hydrothermal stratabound consisting of cross-cutting veins of calcite, dolomite, quartz, specularite, pyrite, chalcopyrite and bornite. Disseminated bornite and chalcopyrite occurs in the limestone wall rocks. Polished section work identified subordinate molybdenite, sphalerite, magnetite and a number of gold grains. Native silver has also been reported.
2.0 GEOLOGY The deposit is hosted by Kundelungu rocks. The rocks are poorly exposed in the area. The copper mineralization is found as malachite vein. The vein is hosted by laterite/ferricrete. The malachite mineralization occurs as vein mineralization. It occurs as green copper carbonate. Cuprite is also present in minor amounts. Haematite, goethite and magnetite are the chief iron ore minerals. These minerals occur as grey, light brown, black and yellow minerals. Ilmenite, magnetite, haematite, rutile, and siderite are present as accessory minerals.

Fig. 3. Magnetics Map covering Plot 17798-HQ-LPL.
The magnetic map (Fig. 3) shows that the plot encompasses the magnetic low in nT (nanoTesla) passing through it. This area is favourable for the occurrence of gold and cobalt mineralization. As the magnetic map shows the mineralization occurs in the area of intermediate nT readings.
3.0 ORE
The copper is found as green malachite. Quartz veins permeate the rock. Fe-ore occurs as brown oxide.
Malachite is exposed at grid reference 12o57’03” south, 26o00’11” east. 3.1 Copper Content Copper content in the rocks was analysed at Geological Survey Department. The analyst used the Niton Analyser. The analysis was done by Mr Brighton Mulenga. The samples analysed as follows: a 35.64 % (Malachite), 5.25 % (Iron) b 32.31 % (Malachite), 2.81 % (Iron) The samples averaged 33.975 % copper and 4.03 iron. This is the average of two samples. 4.0 RESERVES
The completed trenching programme was enough to outline 4860000 tonnes of copper ore; averaging 1.1 – 1.8 % copper (Table 2) (RST, 1969a, b, c, 1970a, b), just on one portion of the 4.3995 square kilometer
7
area. The ore is exposed as copper malachite (CuCO3•Cu(OH)2 ore, chrysocolla (CuSiO23.2H2O or (Cu,Al)2H2Si2O5(OH)4) ore, cuprite ore and azurite (2CuCO3•Cu(OH)2 ore in laterite/ferricrete. Bornite has iridescent tarnish, chalcopyrite has iridescent tarnish, deep brass yellow; cuprite (Cu20) has red colour, azurite is blue, malachite is bluish green. Chalcopyrite has 4.2 approximate specific gravity, bornite is 5.1, cuprite is 6.0 and copper is 8.9. The host rock is brown quartzose rock. The ore is exposed as malachite ore in ferricrete/laterite and siltstone. Getting a specific gravity of 4.0 g/cc (4000 kg/cubic metre) the reserves in tonnes are calculated as: volume of ore = 1500m x 6.0 m x 45 m depth = 405000 cubic metres. The tonnage is 405000 m3 x 4000 = 1620000000 kg = 1620000 tonnes. This is from the area where minor trenching has been done. The strike length has been estimated for 1500 m. Then tonnage is this 1 620 000 tonnes of Cu at 5.6 % from one vein. There are three veins in the plot which have the same mineralization. That is, 1 620 000 x 5 = 4 860 000 tonnes in the whole plot.

Mineral Property Right
The Briamat Mine project area is under a mining right licence 17798-HQ-LPL belonging to Tangeray
Resources Zambia Ltd, P. O. Box 35094, Lusaka
Commodity
Copper and cobalt.
PROJECT VISION AND OBJECTIVE The decision to acquire mining right in the area was made, in addition to other economic reasons, to encourage a systematic and organized copper exploitation venture. As such the overall objective is to avoid wasteful mining practices, both environmentally and economically. The local communities, who are mostly involved in illegal and disorganized mining activities, will be incorporated into the mining venture, thereby providing employment and other socio-economic benefit to them. This is in line with the national vision to alleviate poverty through sustainable natural resource utilization. Further, the socio-economic vision for the mining operation can be summarized as follows: - To discourage illegal mining (for the sake of national benefit through tax from copper exports) - To generate employment opportunities - To discourage wasteful mining practices, environmentally and economically - To contribute to poverty alleviation It is based on the above that capital investment is being sought, for the mine to attain meaningful profit levels and hence fulfill the intended socio-economic objectives of contributing to the uplifting of the standards of living for the Zambian people. To increase the production to profitable tonnage margins, the company needs to invest in capital equipment and other resources essential for a successful mining operation. PROJECT IMPLEMENTATION
Tangeray Resources Zambia Ltd this project with a view to gain experience in mining activities, through operations in the area. Open excavations and pits will be opened and commissioned using hired machinery and hand tools. Local labourers will be used with direct supervision from the directors. The company would like to improve production levels and operation modes by acquiring efficient mining machinery and tools, and engaging expert consultants in mineral resources development. INVESTMENT REQUIREMENTS 17798-HQ-LPL is seeking financial resources assistance to improve its operations in the copper-au-Co mine.

MINING IN GENERAL
OPERATION STATEMENT
The role of mining worldwide, both in developed and developing countries should not be underestimated. The situation in large-scale mining can be characterized by a socio-economic and environmentally related vicious circle that, without external assistance, can hardly be broken. Despite the difficult conditions that beset small-scale mining, the industry holds a substantial position in the mining industry worldwide. Of the total world mining production, a considerable proportion is accounted for by small-scale mining. About 90% of world copper productions is from Chile, DRC and Zambia. Figure A. Large-Scale Mining socio-economic-environmental vicious circle

resources and its deleterious impact on the environment. Mining on one hand, and culture and people on the other, have greatly influenced each other since prehistoric times. Mining activities provided culturally significant metals and precious stones. Mining has always, still to this day, led the way for rural and technological development. Mining, with its tools and equipment, utilizes this technology to generate income through the materials it produces. A comprehensive promotion of large-scale mining must consider the social suitability, assessed needs, profitability and environmental compatibility. Only then can subsequent improvements in the working conditions of large-scale miners be achieved.
LARGE-SCALE MINING IN ZAMBIA
About seventy percent (70%) of mining projects and operations in Zambia are under the category of Large-Scale Mining. It is this category that most Zambian village/rural and other local communities are directly involved in. Mineral resources are widespread through out the country, in both rural and urban areas. The current urban set-up of the world-renowned Copperbelt region was once a rural area that has been transformed and developed due to the mineral resources of copper and cobalt. In Zambia, the large-scale miners have been struggling to operate gainfully. Most of them have failed to exploit the proved reserves of the mineral resources of Zambia. The main reason for this state of affair is lack of investment capital into the large-scale mining activities. The lack of reasonable capital, to enable procurement of machinery and professional human resources, has hampered the smooth operation of the mining rights. Conventional, and most of the times crude and dangerous methods, are used to mine the mineral resources. This has caused social, economical and environmental losses to the nation of Zambia. The nation loses out economically due to unprofessional working modes, which tend to leave out the most valuable minerals resources still buried in unplanned barrows (open pits). The national faces some environmental hazard due to lack of professional advice to the small-scale and large-scale mining communities. Zambia is currently in a phase of trying to alleviate poverty. One of the means being tabled is the sustaining of lives in the rural areas. Supporting rural livelihood socio-economic activities, such as agriculture, is one of the ways to alleviate poverty nationwide. Communities in the peri-urban and rural areas are conducting most small-scale mining activities. As such, small-scale mining activities, in which most of the beneficiaries are local communities, is one of the ways to address the issue of alleviating poverty in the nation. Some donor international communities have realized the above facts. The European Union has provided financial facilities to assist small-scale miners (through a loan) develop their mining ventures to gainful margins and sustain their operations. SOCIO-ECONOMIC AND ENVIRONMENTAL CONSIDERATIONS
Tangeray Resources Zambia Ltd is operating a small-scale mine in rural Solwezi area of North-western
Province. The landscape is flat. Further, the company will operate in an environment friendly manner. Workers will be sensitized on the need to practice safe environmental and human health working modes ZAMBIA AND COPPER, THE CONCLUSION Zambia produces a good amount of copper and cobalt plus uranium and gold. The world copper trade is never complete without the Zambian input. It is anticipated that systematic and organized exploitation of the copper deposits will be promoted and supported by various stakeholders. If properly explored and systematically mined, the copper mine could contribute to Zambia’s GDP.
13
Systematic exploration utilizing modern methods and detailed mapping, and investment support in form of loans, offers considerable potential for the discovery of additional deposits of copper. CONCLUSIONS The copper-cobalt deposits are in rural Solwezi District. The mining of copper ore will be environmentally friendly and the environmental management plan will be drawn later. The character of the site will be preserved No agricultural activities are seen for several kilometres around the sites
Tangeray Resources Zambia Ltdwill do business with Zambian companies.
From copper-cobalt gold uranium mineralisation, 17798-HQ-LPL is seeking investment assistance for copper and cobalt mining.

Vegetation
The Plot 17799-HQ-LPL is a miombo woodland in which
Isoberlinaangolensisand Julbernardiapaniculata are prevalent is a variant
termed mesicmiombo, usually found to occur in high rainfall areas of Zambia.
But a variant of xeric Miombo associated with the low rainfall areas is devoid
of Isoberliniaangolensisand Julbernardiapaniculata.
The Mopane Woodland
The mopane woodland is a one storeyed vegetation type with an open canopy.
It is found in regions with rainfall in the range 400-800 mm per year. Mopane
woodland is dominated by the leguminous taxon Colophospermummopane
(tribe Detarieae in family Fabaceae), a species is known to be endemic in
southern Africa. Taxa found in this woodland include species of Acacia,
Adansonia,Albizia, Combretum, Commiphora, Commiphora,Kirkia, Lannea,
Lonchocarpus, Pterocarpus, Selerocaryaand Ximenia.
Acacia-Combretum Woodland
This is a physiognomic unit characterized by open park-like deciduous
woodland. In the major river valleys, the woodland occurs along the fringe of
Zambezi and Kafue rivers. The woodland is dominated by species of Acacia
and Combretum. Sclerocaryabirrea (Musebe), which is adapted to low
altitudes of the Zambezi valleys.
Drainage
Lufwanyama River flows through the Plot from SE to NW. Museleshi is on the
eastern part of the area.
General Geology of 17799-HQ-LPL
Rocks of Basement Complex comprise biotitefeldsparthic gneiss, hornblende-
biotite gneiss, granitic gneiss, migmatites and schists. These are intruded by
4
younger granites. These basement rocks from the core of the Mwombezhi
Dome and are overlain unconformably by metasedimentary rocks of the
Katanga Supergroup. The Kitungulu Formation at the base is a prominent
ridge-forming quartzite. Overlaying the Kitungulu Formation are domomites
and dolomitic schist, calcareous biotiteshist with slate and banded ironstone,
calcite-dolomite marble of the Chafugoma Formation. This formation outcrops
extensively in both Mwombezhi Dome and Jiwundu Swamp areas, and
together with banded ironstone, forms the topmost unit of the Mine Series. A
conglomerate dolomite within the calcite-dolomite marble of the Chafugoma
Formation marks the top of the Mwashia and is probably equivalent to the
Grand Conglomerate of the Congo and the Copperbelt.
The overlaying rocks of the Kundelungu Group consist mainly of the Solwezi
Formation. This comprises biotiteschists bearing scapolite, amphibolites and
garnet. A conspicuous feature of the schists is the detailed structural
complexity shown by relics of syntectonic crystallized biotieacd rotated garnet
porphyroblasts.
The general structure of the Mwombezhi Dome is basically simple, with the
Katanganseccession dipping off the dome at 30 to 35o. However, in the
middle part of both lobes, extremely complex structure is interpreted as
recumbent folding. Evidence for the existence of this was found in a borehole
in which some of the beds in the inverted limb, including the Lower Roan
Group, were repeated three times (Mindeco, 1976). At least two subsequent
phases of folding were associated with the Lufilian deformation. The
relationship between the overfolding and the formation of the main dome
structure is not known. The first folding was accompanied by extensive thrust
faulting. The structure of highly faulted, fractured calcite-dolomite marbles in
the Jiwundu Swamp area is believed to be a synform.
There are few references specific to mineralization within or past exploration
on 17799-HQ-LPL that were located. It is possible that some mineral
occurrences listed by Guernsey, 1941, lie within the concession, and of so
probably would be located in the southwest. The 1991 Watts Griffiths McOuat
(WGM) report does no matter significant prospect that can be confirmed to
occur within the licence area, however included here is map showing minerals
occurrences as reported by WGM within the vicinity of 17799-HQ-LPL.

The entire plot 17799-HQ-LPL is underlain by Lower Roan with basal
conglomerate; the main copper-bearing unit and Undifferentiated Basement
Complex; mainly granitic gneiss and migmatites.

Magnetic Survey
The magnetic map shows the distribution of magnetic anomalies. The high
values above 300 gammas correspond with Fe-rich areas. The map will show
the magnetic trends in the area. The magnetic anomalies are related to
mineralization. The magnetic map shows the plot to be located between the
magnetic high corresponding to magnetite or pyrrhotite (maroon to orange
colour) and magnetic low (green colour) with literary no magnetic responses.
This zone is conducive for base metal mineralization.
The magnetic map shows magnetic readings in nanoTesla. The very high
magnetic data if from 72.5 – 62.5 nT and is depicted as purple. The red is for
6
readings from 62.5 – 50.5 nT. The orange colour is for readings between 50.5
and 45.8 nT. These are medium readings together with 45.8 – 41.8 nT
(yellow). The low nT readings from 41.8 – 36.6 nT are depicted as green so is
blue colour for 36.6 – 12.2 nT. The purple colour is attributed to magnetite,
pyrrhotite and ilemnite. The colours related to base metal concentration are
yellow and orange, intermediate nT. The low nTcolours are related to non-
magnetic minerals. The faults, mylonitic and brecciated (fractures) zones are
conduits for metalliferous fluids. Exploration and prospecting should not
overlook these structural features.

Previous Work
Large concessions were granted to Copper Venturs Limited, and, in 1923, the
Rhodesia Congo Border Concession Limited (RCBC) was formed to explore
the concessions. From 1923 to 1940, RCBC undertook what was probably
the largest and most comprehensive prospecting campain undertaken up till
then. In fifteen years, 404,040Km2 were prospected and mapped so well that
very few copper and iron occurrences were missed and the maps have stood
the test of subsequent prospecting. Little prospecting was carried out during
7
the Second World War, but Rhodesia Selection Trust Mine Services (RSTMS)
Limited (then Mufulira Copper Mines Limited) resumed exploration in 1947.
Systematic prospecting of 69,900Km2 of the Mwinilunga area resulted in the
discovery of the Lumwana Prospect at the end of 1960. Drainage
geochemical sampling revealed anomalous copper in the area and
subsequent detailed geochemical work and geological mapping preceeded
the drilling of the first diamong drill hoel at Malundwe in November 1961.
This hole intersected 1.33% Cu over 13.41m. by the end of 1964, detailed
geological mapping of the most of degree sheet 1225NE at 1 : 50, 000 scale,
detailed geochemistry, geophysics and drilling had proved copper
occurrences. The RSTMS prospecting technique which was developed to
cover areas as rapidly and efficiently as possible is described by McGregor
(1964). Work was discontinued in 1964, but resumed in 1969 when an
extensive diamond drilling programme was initiated by Mwininlinga (1970)
Ltd.
Work done by Tangeray Resources Zambia Ltd
During the period prospecting period, Tangeray Resources Zambia Ltd
completed to reconnaissance mapping and sampling trips to the 17799-HQ-
LPL area. Rock chip samples from the sound field visit were collected from
old mine dumps and outcrops within the LPL area and the surrounding
environs. All the samples were cobalt and malachite+/- other copper oxide
minerals. Although the samples that were collected, sending to the laboratory
did not become a priority and consequently assay are pending.
Regionally the licence area lie in a relatively Greenfield area in an area that
several copper-gold occurrences occur. These copper-gold occurrences are
generally of small extent. Many exploration successes in this part of Zambia,
in terms of prospect definition, have highlighted the fact that there are many
more conceptual targets in addition to the Copperbelt-type Lower Roan
stratabound copper-cobalt deposits. The possible targets would be epigenetic
stratabound copper mineralisation accompanied by silver, gold and uranium
and /or StrataboundCopperbelt-type mineralization in Upper Roan and even
overlying Kundelungu rocks. The area has potential for IOCG type of
mineralisation also.

support costs incurred by that contactor/consultant. Also expenditure here is
tabled in USD but the reason the amounts appear approximant is due to the
fact that expenditure incurred involves several different currencies.
Future Work & Recommendations
Whilst there is undoubted evidence of base metal mineralization within the
licence area and adjacent, it would seem that these working in themselves
do not have the making of significant base metal deposit. However whilst it
would appear that the copper deposits are not of the classic sediment-hosted
Copperbelt style, there is the possibility of Iron Oxide copper-gold (IOCG) style
deposits in this concession. AIM Resources, east of Kabwe and Zambezi
Resources south of Lusaka have been exploring for this style of
mineralization, and telfer-style with some success at an exploration level.
The fact that exploration companies such as RCM, ZamAnglo, Charter hall
and others active in the 1960s and 1970s did not routinely assay for gold, if
ever, also points to an unrecognized potential for Telfer and Carlin style of
mineralization. Although recent explorers (like Phelps dodge) did assay for
gold with little success, at the conceptual level the potential for gold
mineralization remains backed up by generally anecdotal references to
surface and alluvial gold indication within the district area.

Further work will be conducted cognisant of the potential style of
mineralization and shall include the follows:
1. Mapping and Sampling of alteration zones and surrounding areas.
2. Stream sediment sampling and soil sampling, ensuring that the
samples are assayed for low level gold and also the gold pathfinder
elements e.g., As, Bi, Mo, Sb, and W, targeting areas of alteration and
drainage thereof.
