- Tancoal Energy Limited ("Tancoal") was established on 3 April 2008, as a Joint Venture between the National Development Corporation of Tanzania (NDC) and Intra Energy (Tanzania) Limited (IETL), an 100% owned subsidiary of Australian publicly listed company, Intra Energy Corporation ("Intra Energy") (ASX Code: IEC). The Ngaka Coal Project is Tancoal’s flagship project. Located in the vast coalfields of south western Tanzania, the Ngaka Basin has the potential to host up to 1 billion tonnes of high quality thermal coal. Production of coal started in August 2011 at Ngaka in Mbinga District, Ruvuma Region, where the mine will initially be producing about 30 tonnes of coal per month, but at full capacity the output is projected to reach five million tonnes annually. The amount is well beyond the country's annual demand. Coal from Ngaka, according to investors, will be used in generation of 240MW of electricity by the year 2015. This will be a big boost to power supply in the country. Sources in the ministry of energy and minerals say that the lifespan of Ngaka Coal Mine is about 50 years.
- Leaving coal from Ngaka apart, Tanzania's energy industry is set to gain significantly from other coal fields. There is 800MW from the Mchuchuma and Kiwira coal mines in Njombe and Mbeya regions, respectively. In June, last year, the government announced that China would invest 400 million US dollars (abot 630bn/-) in the Kiwira coal mine project estimated to generate 200MW of electricity. The money, according to officials with the ministry, is expected to come under soft-loan arrangement. In September, last year, China's Sichuan Hongda Company Limited, signed a 3 billion US dollars (about 4.7tri/-) deal with the National Development Corporation (NDC) to mine coal and iron ore in Tanzania. The investment involves construction of the Mchuchuma Coal Mine and an accompanying 600-megawatt (MW) thermal power station. It is estimated that Mchuchuma coal deposits have more than 480 million tonnes of coal reserves. However, as the Minister for Energy and Minerals, Professor Sospeter Muhongo, rightly pointed out at the weekend that relevant authorities must act vigilantly to ensure Tanzania is not short-changed in all contract involving power supply. It is hoped that in all transactions, the win-win scenario will be achieved.
- Kibo Mining plc has been engaged in ongoing discussions with the Tanzanian Government and potential development partners regarding the development of a mouth-of-mine coal thermal power plant (“Rukwa Coal to Power Project”). Rukwa currently contains a JORC-compliant resource of 109 Mt of thermal coal (71 Mt of which is in the Indicated category and 38 Mt in the Inferred category) and it is anticipated that the proposed scoping study will quantify preliminary technical and economic parameters for a mining operation prior to completion of a feasibility study. The Company expects the results of the scoping study to be available towards the end of the year.
- Petra Diamonds completed the acquisition of the Williamson Diamond Mine (Petra 75%, Government 25%) from De Beers in February 2009. Williamson is the world’s largest economic kimberlite by surface area at 146 hectares in size. The Mwadui kimberlite pipe, upon which the Williamson mine is based, contains a diamond resource of approximately 39 million carats.14 alluvial diamdiferous placers have been documented but only two deposits derived from adjacent kimberlites have been described in detail. The New Alamasi deposit is located about 2,5 km east of the Mwadui kimberlite and consists of a calcretized, diamondiferous gravel resting on palaeo channels excavated into Archaean bedrock. It is thought to be Palaeogene in age and was deposited by ephemeral streams emanating from the Mwadui kimberlite. The grade averages 5,9 cpht, but the quality of the diamonds is unknown. Approximately 1,5 million carats of diamonds have been produced from this deposit. The Boshoff deposit, which has been fully exploited is a Tertiary colluvial gravel placer that extends up to 1 km away from the Kisumbi diamondiferous pipe near Shinyanga. This deposit produced a total of 7 334 carats with an average grade of 12 cpht and a stone size of ;3 carats. The other 12 placers are located to the southeast of Arusha, northeast of Lake Rukwa and at isolated sites in the east and extreme south of Tanzania. No other information is currently available, apart from the fact that one placer, 250 km southwest of Lindi, contains large stones of exceptional quality, some of which exceed 10 carats..
A new tectonic and temporal framework for the Tanzanian Shield: Implications for gold metallogeny and undiscovered endowment

The major metallogenic significance of the new tectonic subdivisions is the recognition of under-explored belts: 1) in the gold-endowed East Lake Victoria and Lake Nyanza Superterranes, Lake Victoria Region. Here deeply weathered belts in the Musoma–Kilimafedha, Kahama–Mwadui and Nzega–Sekenke Terranes and belts, situated in tectono-thermally reworked crustal blocks such as the Iaida–Haidon, Singida–Mayamaya and Mara–Mobrama Terranes, are predicted to be prospective; 2) in the Dodoma Basement Superterrane, Central Tanzania Region, where relatively thin, juvenile granitoid-greenstone belts, similar to the ~ 2815–2660 Ma Mazoka Belt in the Undewa–Ilangali Terrane, contain small-scale gold systems with analogous terrane-scale geologic settings and evolution histories to those of gold-hosting greenstone belts in the Sukumaland Terrane, Lake Victoria Region. The overall geologic–geometric setting of the greenstone belts in the Central Tanzania Region (Mazoka-type) is comparable to those of the gold-hosting juvenile granitoid-greenstone belts in the South West and Youanmi Terranes, Yilgarn Craton, Western Australia, and North Superior and North Caribou Superterrane, northwestern Superior Craton, Canada; and 3) in the Proterozoic Tanzanian Regions, where terranes that lie in close geographic proximity and regional strike extension to the gold-endowed Lake Nyanza Superterrane are likely to be most prospective. They include the Archean Nyakahura–Burigi Terrane in unroofed thrust windows of the Mesoproterozoic Karagwe–Ankolean Belt of northwestern Tanzania, and the Kilindi–Handeni Superterrane where Archean proto-crust has been reworked by Pan-African tectonothermal events in the Southern East African Orogen.
Gold deposits in Tanzania (Source: Southern African Development Community, Mineral Resources Survey Programme No 4, 2001)
- AngloGold Ashanti (NYSE:AU) operates the Geita mine, 80 kilometres south-west of the town of Mwanza. It produced 613 000 oz of gold in 2005 and proved and probable ore reserves were then estimated to be 62,4 million t at a grade of 4,23 g/t Au or 264,3 t of gold. Geita is an Archaean mesothermal, mainly banded ironstone formation (BIF)-hosted, deposit. Mineralization is found on sheared BIF-diorite contacts and in the diorite as well. At Bulyanhulu mine, the geology consists of mafic volcanic flows overlain by a series of pyroclastics and ash tuffs. Argillite is present at the contact between the mafic and felsic rocks. The gold, silver and copper mineralization on the property occurs in mineralized “reefs” or quartz veins localize along steeply dipping northwest striking structures, generally localized in the argillite units.
- Barrick Gold Corporation (NYSE:ABX; TSX:ABX) operates the Bulyanhulu mine, approximately 55 kilometers south of Lake Victoria and approximately 150 kilometers from the town of Mwanza. It produced 311 000 oz of gold in 2005 and proven and probable reserves were then estimated at 10,7 million oz of gold. Barrick also operates he North Mara mine, approximately 100 kilometers east of Lake Victoria and 20 kilometers south of the Kenyan border. It produced 250 000 oz of gold in 2005 from three open pits. The North Mara mine is situated within the Mara Greenstone Belt, part of the larger Lake Victoria Greenstone belt. The underlying geology comprises felsic and mafic volcanics intercalated with sediments which are intruded by various granitoid and gabbroic plutonic rocks. Tertiary volcanic lava flows partially cover the underlying Archaean geology and the ore bodies are structurally controlled, shear-hosted lode gold deposits. The Tulawaka mine is a joint venture with Northern Mining Explorations Ltd or Minieres du Nord (MDN). The mine is located approximately 1,000 kilometers from Dar es Salaam and 120 kilometers west of Barrick’s Bulyanhulu mine. The mine started producing in 2005 and Barrick's share was 87 000 oz of gold. Tulawaka gold production reached a total of 178 618 oz in 2007, compared with 139 655 oz in 2006 - a 28% production increase. In 2007, a total of 176 508 oz of gold were sold, entirely in the spot market, at an average price of $709/oz compared with an average price of $606/oz in 2006. Total revenues in 2007 were $125,1-million compared with $88,7-million in 2006, which showed an increase of 41%. The Tulawaka East gold deposit is hosted in a complex upper greenschist to amphibolite facies metamorphic terrain comprised of metasediments, including a minor component of metasilicate-iron formation and metagabbro dykes or sills. The local stratigraphy has been folded into a large-scale Z-shaped fold that plunges to the south. The anticline portion of the fold has been cut by a thrust fault sub-parallel to the south-dipping fold axial plane. Gold occurs principally as free gold within quartz veins or stockworks, often associated with felsic intrusives.In 2006, Barrick completed a positive feasibility study for Buzwagi, along with 40 per cent of the project's detailed engineering plans. It conducted 200,000 meters of exploration drilling on the property, and identified further targets. Buzwagi has proven and probable reserves of 2,64 million ounces of gold and contains 118 million pounds of copper within the gold reserves; the estimated mine life is 10 years. Its close proximity to Barrick's Bulyanhulu and Tulawaka operations brings significant synergies, including shared infrastructure, personnel, training and equipment. Buzwagi's average annual production is expected to be 240,000-250,000 ounces of gold at total cash costs of $280-290 per ounce of gold. Capital costs are expected to be approximately $400 million (excluding capitalized interest). It expected Buzwagi gold mine to be in production in 2009. Tulawaka Gold Mine ceased mining operations in March 2013 after its reserves became economically unviable for extraction and refining. Tulawaka was a combined underground and open pit gold mine. It was operated by African Barrick Gold, who owned majority shareholding of 70%. The remaining 30% belong to Northern Mining Exploration Limited. The current Tulawaka mines, owned by African Barrick Gold plc (ABG) has been handed over to Tanzania's State Mining Corporation (STAMICO). The Deputy Minister for Energy and Mining, Mr. Steven Masele confirmed to East African Business Week early June, 2013 that Tulawaka has ended up its operations and handed over to STAMICO. Asked on what the state mining corporation is going to do with the mines, Mr Masele said STAMICO would operate open cast mining.

Early stage exploration is underway by the joint venture partner, Canaco Resources Inc (CAN.V; CANWF.PK)
- IAMGOLD Corporation's Buckreef project is an advanced exploration project located in the Lake Victoria Goldfields of northern Tanzania. During the first half of 2007, 26,000 metres of reverse circulation drilling was completed. This program validated the continuity of a new oxide zone with a strike length of more than 400 metres that lies outside of the known resource areas. This prospective new resource will be drilled as part of the second half $2.9 million, 8,500 metre exploration plan. The current program includes regional exploration testing 7 of 20 new targets and additional detailed metallurgical studies required for a prefeasibility study. The decision to formally undertake the prefeasibility will be made by the end of 2007.
- WCP Resources Ltd is involved in the exploration of prospecting licences that cover three Archaean gold prospects in Tanzania. These consist of Simba Sirori Gold Project located within the southern part of the Musoma greenstone belt and is located 10 kilometres south-southwest of the North Mara Mine (3.3 million oz gold) owned by Barrick Gold Corporation in northern Tanzania; the Magamba and Siga Hills projects, subject to JV with Barrick, located 15 kilometres south of the Nyanzaga property on which Barrick and Sub-Saharan have announced a 4.5 million oz resource; and the Bukoli Project, subject to JV with Iamgold, strategically located at the southeastern end of Iamgold's Buckreef project area (Inferred Resource of 1.93 million oz gold).
- Tanzanian Royalty Exploration Corporation (Canadian, Amex:TRE), by mid-2005, held 138 prospecting licenses in the Lake Victoria goldfields, a large number of which are subject to royalty agreements with Barrick Gold, Anglogold-Ashanti and Northern Mining Explorations. The Company's Itetemia property is adjacent to Barrick's 12 million ounce Bulyanhulu gold mine and remains a prime candidate for the discovery of an economic mineral deposit. It has concluded an option agreement for its Luhala and Itetemia Projects with a private United Kingdom based company, Sloane Developments Ltd. Another eleven projects are the subject of royalty agreements with Montreal-based Northern Mining Explorations whose Tulawaka gold project involves a joint venture with a subsidiary of Barrick. It was
announced in December 2014 that 10 million US dollars (17.22bn/-) has been
closed in escrow and up to 3,642,857 common share purchase warrants for an
institutional lender that will provide money to develop Buckreef gold mine
project jointly owned by Tanzanian Royalty Exploration Corporation (TRX) and
State Mining Corporation (Stamico). In a statement issued, TRX Chief Executive
Officer, James Sinclair said the facility may be increased to 15 million US
dollars (25.83bn/-) subject to financial criteria. "The company will apply
the proceeds of this financing to complete the final 10 per cent of
construction of the first phase of its Buckreef gold mine and to add to its
working capital," the news release stated."On the heels of our
consistently successful drilling activities at Buckreef, this capital will
allow TRX keep its development plan on track," said Joseph Kahama who is
Chief Operating Officer of TRX. "With the many challenges facing gold
companies, this is an opportune time to purchase machinery and hire skilled
local workers and contractors," Mr Kahama noted.
- African Eagle Resources plc has defined a 520,000 ounce gold mineral resource to JORC standard, of which 71% is in the indicated category at the Miyabi gold project in the Lake Victoria Goldfield. African Eagle has begun pre-feasibility studies at Miyabi. On 3 May 2007 the company announced that had entered into a joint venture with a wholly-owned subsidiary of Randgold Resources on its 500 000 oz-plus Miyabi gold project. Under the initial option, Randgold Resources will carry out and fund an agreed phase 1 exploration programme by the end of May 2008.This programme will consist principally of a series of diamond drill hole fence lines to investigate the geology, structure and controls on mineralisation, across the width of the Miyabi corridor.Randgold Resources will then have the right to earn a 50% interest in the project by conducting and funding a prefeasibility study to agreed parameters.Following the prefeasibility study, African Eagle can retain a 49% stake in the project by cofunding a full feasibility study, or dilute to a 35% stake if Randgold Resources provides the funding in full.

On the third anniversary, IGL shall pay the vendor USD$50,000 to earn an extra 15% to take its interest in the tenements to 90%. The Company can at its sole discretion pay the vendor, USD$500,000 at any time during the joint venture period to gain control of 100% of the tenements.
- Shanta Gold Limited operates the New Luika gold mine in the Lupa Goldfields, operational and producing gold from Q3 2012, and is conducting initial exploration on projects in the Mgusu, Simba Nguru, and Musoma districts in Tanzania. The company is also involved in four other early exploration stage projects in Tanzania. Results at the Singida project for 2007, indicate a total gold resource in excess of 543,000 oz, of which 330,000 oz have been classified as a measured resource and 127,000 oz as an indicated resource.
- Gulf Resources Limited (ASX: GLF) signed an option agreement in November, 2007, to review the potential of jointly undertaking, with a Tanzanian partner, scoping studies with the aim of developing and financing a gold project in central Tanzania. The project is located in the Handeni and Bagamoyo district in north east Tanzania and covers some 123 km2.
- East Africa Metals Inc is a Vancouver-based mineral exploration company and its key asset is the Magambazi gold project in Tanzania, which was discovered by the Company in 2009. Magambazi is estimated to contain an indicated mineral resource of 15.2 million tonnes grading 1.48 grams per tonne gold and containing 721,300 ounces, as well as an inferred mineral resource estimate of 6.7 million tonnes grading 1.36 grams per tonne gold and containing 292,400 ounces.
Gold was discovered by locals in the Magambazi area in 2003, spurring a gold rush with intense alluvial and hard rock mining. Canaco acquired the Handeni property in 2007 and began drilling at Magambazi in 2009. The first hole proved to be the discovery hole, returning 53 metres grading 4.32 grams per tonne gold. Further drilling in 2010 was carried out over much of the approximately 960 metre strike length of the Magambazi hill. In 2010, mineral resource drilling was initiated on section lines that were spaced 40 metres apart to define the extent and quality of the observed gold mineralisation. By April 2012, 471 diamond drill holes had been drilled for a total of 121,846 metres on the Handeni property, of which 442 holes totalling 113,692 metres were related to resource definition on Magambazi hill. Findings from approximately 400 of these holes were used as the basis for the initial mineral resource estimate announced on May 15, 2012. The remaining holes were released on July 20, 2012, and are not expected to significantly affect the mineral resource estimate.
Situated in the Paleoproterozoic Usugaran/Ubendian Metamorphic Terrane, and along the northern extension of the north-trending Proterozoic Mozambique Mobile Belt, the Handeni area hosts the metamorphosed eastern extension of the Lake Victoria cratonic belt and as such is considered prospective for Archean greenstone-related orogenic lode-gold mineralization and deposits. The geology of the Handeni area is characterized by variably deformed amphibolite facies para- and ortho-gneisses, and amphibolites, with evidence for thrust faulting and the later development of a northwest trending mineralized shear zone in the northeastern portion of the property.
Gold deposits on the Handeni property consist of artisanal placer deposits and orogenic vein-related mineralization in altered amphibolite gneiss. The host assemblage is interpreted to represent an original metamorphosed Archean lode-gold terrane (predominately mafic volcanic and mafic volcaniclastic rocks) that has been entrained within the Proterozoic Usugaran belt, and undergone further alteration/metamorphism during the Proterozoic Eon. A prominent east-northeast trending thrust cuts across the northern portion of the property. Additionally, mineralization in Lake Victoria is also concentrated along northwest-trending faults. Both of these features are present in the Magambazi area. Many of the significant gold deposits of the Lake Victoria area are spatially associated with iron formation; however, this relationship has not currently been noted in the Handeni area.
At Handeni, artisanal alluvial placer deposits are located at Magambazi, Magambazi North, Kwadijava South, Kwadijava, and Majiri. At Magambazi, Magambazi North, and Kwadijava, artisanal workings occur in quartz-vein-related gold, with mineralization located within silica and garnet altered amphibolite gneiss. Garnet in these altered sections is generally fine grained (<2 millimetres) and the altered zones typically display only a vague banding texture as compared to associated gneisses. The depth extent of these mineralized systems has been confirmed by diamond drilling.
The gold mineralization exposed at Magambazi through mapping and drilling has significance with respect to establishing a deposit model that can be applied to exploration in the region and potentially as a deposit with extensions that project onto the Handeni property. Field observations indicate the Magambazi prospect contains numerous significant bedrock artisanal workings that are located on the western flank of an 11 kilometre long geochemical anomaly. Local miners are exploiting gold mineralization within steeply dipping, north-northwesterly-trending occurrences of sulphide and quartz veins.
From surface, mineralized occurrences are being mined by artisans over widths up to 10 metres, and these define a north-northwesterly trend with a total strike length of 350 metres. Drilling has confirmed that this mineralization continues at depth, and is traceable laterally beyond the known surface extents of mineralized showings for a distance of 960 metres. Mineralization is characterized as vein-related structurally controlled orogenic gold associated with pyrrhotite, arsenopyrite (löllingite), trace amounts of galena and chalcopyrite, and locally graphite. The immediate host rocks are garnet-silica altered amphibolite, enclosed within a sequence of interbedded paragneiss and amphibolite. Multiple mineralized intercepts have been encountered, and two main types of gold mineralization are observed from diamond drilling at Magambazi: high-grade gold associated with pervasive silicification on the postulated footwall of the main Magambazi Fault, termed the Magambazi Lode (D. Groves, 2012); and low-grade gold in an apparent stratabound relationship occurring to the west of this fault.
Structurally, two major steep faults trend northwest along the orientation of the mineralized system, although the nature of the rock in the main mineralized zones is competent their actual fault plane is difficult to definitively identify. The alteration and later metamorphism appear to have annealed the areas of significant mineralization. This, and the decrease in pronounced compositional banding, suggests a high-grade metamorphic overprint of an originally lower metamorphic-grade orogenic gold deposit.
At depth, mineralization trends at Magambazi and Magambazi North are similar in a northwest orientation, but vary in dip and plunge direction. At Magambazi, mineralization dips steeply to moderately west, and plunges northwest. In contrast, mineralization at Magambazi North dips moderately to gently east, and plunges southeast. The fact that the Magambazi North mineralized zone dips in a direction opposite to that of the interpreted main foliation, while also paralleling the trend, suggests the primary depositional environment hosting gold mineralization likely predated the last major compressive tectonic event.
Initial Mineral Resource Estimate
In December 2011 Canaco commissioned an initial mineral resource estimate for the mineralized portion of the Magambazi area. The results of this work were announced on May 15, 2012, reporting an initial mineral resource estimate of 15.2 million tonnes grading 1.48 grams per tonne gold and containing 721,300 ounces in the indicated category, as well as 6.7 million tonnes grading 1.36 grams per tonne gold and containing 292,400 ounces in the inferred category.
- Tanzania Minerals Corporation (TZM) has focused its exploration efforts in the Lake Victoria Goldfield, Musoma District and has 100% ownership of three key concessions in this area that are currently being developed. The Mrangi Project is the most advanced at the current time, as TZM has been actively working on Phase 1 of it's exploration plan on this concession . Katario (Mrangi East) and Kibara (Mrangi South) have recently been acquired as they are in close proximity to the Mrangi Project.
- Kibo Mining plc is an Irish registered company established in 2008 to focus on exploration and development of gold and nickel deposits in Tanzania. Its shares are quoted on the Alternative Investment Market (AIM) of the London Stock Exchange and on the AltX board of the JSE in South Africa. Its projects are located both in the established and gold prolific Lake Victoria Goldfields, the emerging goldfields of eastern Tanzania and the Mtwara Corridor in southern Tanzania where the Government has prioritised infrastructural development attracting significant recent investment in coal and uranium.
- Kibaran Nickel Limited (ASX: KNL) has reported the discovery of large flake graphite from its Mahenge Graphite Project in Tanzania. In May 2012, Kibaran Nickel acquired Tanzgraphite, which owned the Mahenge and Merelani-Arusha graphite projects in Tanzania. The Mahenge project hosts the Ndololo, Epanko and Kasita graphite prospects and consists of two tenements covering an area of 325.5 square kilometers. Drilling at the Mahenge and Merelani-Arusha graphite prospects expected to begin in mid-July 2012. Geological mapping at Ndololo prospect delineated the graphitic schist to occur over at 17.4 kilometer strike length -- three times larger than historically recorded at 5.0 kilometers. Large flake graphite up to 9 millimeters in diameter is continuous along the strike length. An additional graphitic schist occurs over a 13.6 kilometer strike length at the Kasita and Epanko prospects. The Merelani-Arusha graphite project consist of 7 tenements covering 973.4 square kilometers and flake graphite of up to 10 millimeters in diameter has been observed. Geological mapping has observed a graphitic schist of over 1.5 kilometers in length with an average width of 200 meters. Previous work carried out by Tanzgraphite’s geologists and available technical data provides information to estimate a potential exploration target of between 3.5 million tonnes and 7 million tonnes of graphitic schist grading between 10% and 15.5% Carbon for the Ndololo graphite project.
- Uranex Limited (ASX:UNX) reported first graphite assays in September 2014 from a drill program on its Nachu Graphite Project in Tanzania that have shown graphitic schist and potential mineralisation is present in multiple horizons. Over 14,100 metres have been drilled so far in 2014. In 2014, 122 drillholes including 106 Reverse Circulation (RC) and 16 Diamond core drillholes have been completed to date for a total of 14,180 metres drilled. More assay results were expected in the coming weeks. These will be incorporated in a maiden JORC Resource due for November 2014. High grade graphite intercepts on multiple blocks included:
- 27m at 8.7% Cg from 9m, including 6m @ 18.3% Cg (NARC057)
- 21m at 9.5% Cg from 137m, including 8m @ 11.3% (NARC063)
- It was reported in July 2013 that Tanzania China International Mineral Resources Limited (TCIMRL), a joint venture between the National Developm\ent Corporation and Sichuan Hongda Group, manages the MCHUCHUMA-LIGANGA twin coal and iron projects. Exploration indicated 364 million tonnes of coal and 219 million tonnes of iron ore at the twin projects. It is estimated that three million tonnes of coal will be mined annually and 2.9 million iron ore every year
- In 2005, Falconbridge acquired a 50% indirect interest in the Kabanga nickel project in Tanzania from Barrick, which retains the remainder. Falconbridge is the operator of the joint venture. The project is located in northwestern Tanzania, south of Lake Victoria and near the Burundi and Rwanda borders. The current estimated inferred resource is 26,4 million tonnes grading 2,6% nickel based on estimates released by Barrick (February 2003). Xstrata Nickel, a subisidiary of the London-listed mining firm, said in February, 2007, it would spend $95m completing a prefeasbility study of Kabanga nickel. Xstrata also said Kabanga had an estimated indicated resource of 9,7 million tonnes of nickel grading at 2,37% nickel and a total estimated inferred resource of 36,3 million tonnes grading 2,8% nickel.
- African Eagle Resoueces plc has bee exploring the Dutwa nickel deposit. The deposit lies in the Kilimafedha belt (Swahili for "money hills") of the Lake Victoria Goldfield. Greenstones and granites underlie the area. The greenstones, of Archaean Nyanzian age, are mostly metamorphosed volcanic and sedimentary rocks, with some banded iron formation in the east. Several large ultramafic bodies intrude the greenstones, the nickel laterites form a blanket up to 80m thick on top of these. To investigate the main nickel anomaly, African Eagle undertook trial drilling in June 2008. The results were very encouraging and a 139 hole reverse circulation (RC) drilling programme was completed to delineate the resource. The Company also undertook a 10 hole diamond drill programme to obtain core samples for metallurgical testing and density measurements. From the results of this drilling independent consultants SRK Consulting (UK) Ltd estimated a maiden JORC inferred mineral resource in November 2008. The Dutwa nickel oxide project consists of two hilltop deposits, Wamangola and Ngasamo, which form thick residual lateritic caps on the tops of low ridges 7km apart. Combined the two deposits have a JORC Indicated and Inferred resource of around 100Mt at circa 1% nickel. 94% is in the Indicated category with the ferruginous siliceous ore ("FeSi") comprising 70% of the total resource. As announced on 12 September 2012, the Wamangola FeSi ore is strongly amenable to beneficiation and demonstrates improved leach characteristics compared to run-of-mine ore.
- Castillian Resources Corporation has acquired a 100% interest in four properties in the Kagera Belt, Tanzania. The key claims are approximately 10 km northeast of the Kabanga nickel deposits of Xstrata/Barrick. Mapping indicates a 20 km long belt of prospective mafic and ultramafic rocks on trend with the Kabanga deposits.
- Albidon Ltd is involved in the the Luwumbu Project, situated in the Livingstone Mountains of southwestern Tanzania, which is owned 90% by Goldstream Mining NL and 10% by Albidon. In June 2003 an agreement was signed whereby Lonmin plc may earn a 70% interest in the project by sole funding a Feasibility Study on an Indicated Mineral Resource. The Songea Project comprises five Prospecting Licences in SW Tanzania covering an area of 4,093 sq km, and is part of the Albidon-BHP Billiton Africa Exploration Cooperation Agreement. Published geological maps indicate that rocks in the Songea Project are similar to those on the Luwumbu Project, along strike to the north, where significant platinum mineralization has been identified.
- Goldstream Mining NL is exploring the Nachingwea Project (Goldstream 100%) which consists of four granted tenements totaling 7,300 square kilometers, located in south eastern Tanzania. Follow up of historic drainage anomalies has located two ultramafic trends. Orientation soil sampling over the ‘Nditi’ pyroxenite returned highly anomalous values of 6,932ppm Cu, 7,760ppm Ni and 1,2g/t PGE. The body appears to extend over 5 by 2 km. The company has announced announced plans to divest its Nachingwea nickel-copper project in a $12 million to $17 million initial public offer on the Toronto Stock Exchange. The ASX listed Goldstream will spin-off its Continental Nickel Ltd subsidiary, but will maintain a 51 per cent stake in the company, as well as a 25 per cent free carry through to the completion of a feasibility study or until CNI incurs a minimum level of expenditure. Continental will also have the right to acquire further nickel projects, with at least $8.6 million in IPO proceeds being committed to proposed exploration of the site. Continental Nickel Ltd is now exploring the Nachingwea Project. The project is 70:30 joint venture between Continental Nickel and Goldstream Mining NL and Continental is the project operator. The land holding comprises 17 granted prospecting licences totalling 3,199 sq km with an additional 25 licence applications totalling 4,814 sq km pending. During the period 2004 to 2006, Goldstream carried out field programs on the Nachingwea property comprising surface sampling, a small VTEM survey, ground geophysics and drilling (17 holes totaling 2,153 m). This work culminated in a significant new greenfields nickel sulphide discovery in June 2006 when drillhole NAD13 intersected 11.23% Ni, 1.74% Cu and 0.15% Co over 3.0m including 15.87% Ni, 2.61% Cu, 0.21% Co, 0.49 g/t Pt and 0.32 g/t Pd over 1.68m. This mineralization was intersected at a vertical depth of 65m at the contact between ultramafic and metasedimentary lithologies. Eleven other holes returned significant (>0.5%) nickel values from the mineralized intercepts over core widths of 0.5 to 23.0 m. Previous work by other companies included mapping, trenching and drilling (6 holes totaling 1,302m) by INCO during the period 1950-1953 and a regional magnetic/radiometric airborne survey and stream/soil sediment sampling by BHP between 1996 and 1998.
- Tanzanian Royalty Exploration Corporation holds seven prospecting licenses representing a combined area of4,434 square kilometers within the Kabanga nickel belt.
- Kibo Mining plc's Haneti Nickel Project is a joint venture with Brazilian industrial conglomerate, Votorantim. Priority focus is on those localities with elevated nickel (up to 13%) and PGMs (up to 2.3 g/t combined Pt & Pd) within the nickel-PGM-copper prospective Haneti-Itiso Ultramafic Belt identified from the Company’s previous work on the project. Extension of soil sampling and ground geophysical grids around these localities are in progress to further resolve existing drill targets and to generate others; also regional exploration comprising geological mapping, soil sampling and stream sampling to target both nickel sulphide and gold mineralisation; as well as diamond drilling on geochemical and geophysical targets at the Mihanza, Mwaka,Kwahemu and Sanato Hills localities. A 1,000m diamond drilling programme is planned over these localities toward the end of 2013 or early in 2014.

- Natural gas proved reserves: 22.65 billion cu m (1 January 2005 est.)
- A second licensing round, since 2000, covering deepwater acreage to the north of Dar es Salaam was concluded in August 2002, calling for bids on 12 blocks. Bids were received from only two companies, Shell and Global Resources, both interested in blocks 9-12. In October 2002, exploration rights were granted to Shell for all four blocks. Shell conducted 2D seismic surveys of the areas, and will use the results to conduct 3D seismic surveys. Royal Dutch/Shell hoped to begin exploration in 2004 on its four deep-water blocks.
- Artumas Group Inc operates the Mnazi Bay Concession. The Mnazi Bay exploration and production concession covers a 756 sq. km area in south eastern Tanzania, bordering Mozambique to the south and lying along the north eastern flank of the Rovuma River. In 1981, AGIP (now ENI) drilled a shallow water, off-shore well and discovered the Mnazi Bay Gas Field. However, due to a lack of a commercial gas market at the time, AGIP capped the well, leaving the wellbore integrity intact, and relinquished the concession. In 2004, Artumas acquired the rights to the Mnazi Bay concession. With no signature bonus requirement, the Company committed to provide a gas-to-power energy solution for the Mtwara/Lindi region to replace their existing unreliable, aging system. This has become known as the Mtwara Energy Project. New seismic data and interpretation indicates the Mnazi Bay Gas Field to be more than double the size of original estimates, covering some 75 square kilometers in aerial extent versus the original estimate of 34 square kilometres.
- Tullow Oil plc has agreed a farm-in deal with Ndovu Resources Limited, a subsidiary of Aminex plc, which involves the company earning a 50% interest in two licences in the Tanzanian portion of the Ruvuma Basin. Tullow will be appointed Operator upon completion of the farm-in commitment and will provide technical support during the seismic acquisition programme. The farm-in deal and subsequent change of operatorship are subject to formal approval from the Tanzanian government. The acreage involved lies approximately 500 km south of Dar es Salaam, along the Mozambique border and comprises the Mtwara and Lindi licences which cover a total area of 12,361 sq km. The licences are adjacent to the Mnazi Bay gas field, discovered in the 1980's and currently under development. The area was last explored in the 1980's and prior to recent activity less than 1,400 km of 2D seismic had been recorded. Numerous leads have been identified by previous operators from this data, many with significant potential. Initial targets will be Tertiary and Cretaceous reservoirs. Oil seeps are known in the area.
- Aminex plc is exploring the Nyuni and Ruvuma licence areas. The Nyuni-1 well was drilled to nearly 4,000 metres during 2003/4 and encountered numerous oil and gas shows in a thick but complex reservoir sequence. The well did not flow commercial quantities of oil and gas under limited test but established the presence of live crude oil from a wide-ranging Jurassic source, opening up the prospectivity of the whole region.In the period 2005-7 new marine 2D seismic and transition zone 2D seismic was acquired over the Nyuni licence.In 2007 Aminex farmed out interests to Key Petroleum Ltd. (20%) and to RAK Gas Commission (25%). In addition East Africa Exploration Ltd. earned a 10% interest through contributing new seismic valued at $2 million. An earlier provisional farm-out to East Coast Energy Ltd. was never finalised.In April 2006 Aminex signed a contract with Caroil of France for the use of the Caroil-6 drilling rig to drill two wells on the Nyuni licence. Mechanical delays with this rig have delayed first spud date until Q4 2007.In late 2005, Aminex finalised a PSA for the Ruvuma onshore/offshore area in South Tanzania covering 12,000 sq km. Before end 2005 Aminex had acquired 500km of new seismic in the offshore part of the licence.Onshore seismic is being acquired over Ruvuma during 2007 and a first well location selected with planned drilling in 2008.
- Bounty Oil & Gas NL has a 10% share (Aminex-60%, Petrom SA, the state oil company of Romania-30%) of the Nyuni Block of 2860 km2, located just off the coast of Tanzania, 200 kms south of Dar es Salaam. Adjacent to the permit is the Songo Songo gas field, which contains 590 Bcf (proved and probable) of recoverable gas. The proven reserves are contracted to the Ubungo Power Plant. A 12-inch diameter pipeline capable of transporting 105 mmcfgd (uncompressed) from the field to shore has been completed and a 16-inch 120 mmcfgd pipeline up to Dar-Es-Salaam is under construction and due for completion in May 2004.
- In May 2005, the Tanzania Petroleum Development Corporation (TPDC) offered Ophir Energy (U.K.) , Statoil ( Norway ) and Petrobras ( Brazil ) production sharing agreements (PSAs). In October 2005, Ophir Energy signed the PSA for Block One, while Statoil and Petrobras are still negotiating contracts for their PSAs.
- In 2004, TPDC signed with Petrobras for deepwater Block Five, off Mafia Island and with Maurel & Prom (France) for acreage along the coast.
- Shell has yet to finalize an agreement for Blocks 9 - 12 near Zanzibar and Pemba Islands, which it won over two years ago.
- Dodsal Hydrocarbons and Power (Tanzania) Pvt. Ltd. (a wholly owned subsidiary of Dodsal Resources) signed a Production Sharing Agreement with Ministry of Energy and Minerals and Tanzania Petroleum Development Corporation for exploration of oil and gas for the RUVU block which is approximately 15,300 square Kilometers.
- Discussions are ongoing between government and Petrobras of Brazil for oil and gas exploration in the deep waters of Block No 8 and Tullow Oil of UK for exploration in Northern Lake Tanganyika.
- Total to search for oil in Tanzania (Source: WHAT YOU NEED TO KNOW | STAFF WRITERAUGUST 16, 2011 AT 15:14) Tanzania has awarded oil and gas exploration rights for the northern side of Lake Tanganyika to a subsidiary of French energy company Total SA, its state-run petroleum agency said on Tuesday. The Tanzania Petroleum Development Corporation (TPDC) said in a statement on its website Total E&P Activites Petrolieres beat eight other bids from Australian, Canadian, British and American companies for the Lake Tanganyika North Area block. “Total E&P Activites Petrolieres has shown to be able to comply with the minimum work commitment and has superior technical as well as a financial capability over the other bidders to undertake exploration in the Lake Tanganyika north area,” TPDC said. Interest in East Africa as a new hydrocarbon region has been heating up in recent years after major discoveries of oil in Uganda and natural gas in Tanzania and Mozambique. Lake Tanganyika is shared between Tanzania, Democratic Republic of Congo (DRC), Burundi and Zambia. TPDC has divided the Tanzanian side of Lake Tanganyika into two blocks, with the southern portion awarded to Australia’s Beach Energy in 2008. Beach Energy was among the unsuccessful bidders for the northern block. Oil majors Aminex Plc , Ophir Energy and U.S. independent ERHC Energy had also submitted bids for the oil and gas exploration rights in the Lake Tanganyika north area. Despite having natural gas deposits, Tanzania is yet to strike oil. Brazilian petroleum company Petrobras expects to start exploration in September for oil and gas off the coast of Tanzania, which is known to have significant gas deposits. Tanzania postponed its fourth deep offshore bidding round to next year to allow it to offer new blocks discovered by a latest seismic survey. The bidding round, which was initially scheduled for April, was expected to invite bids for 13 deep offshore blocks located around 1,200 and 3,000 metres below sea. Among the 17 firms that hold exploration blocks in Tanzania are France’s Maurel & Prom, Norway’s Statoil, Royal Dutch Shell and Ras al-Khaimah Gas Commission of the United Arab Emirates. (Reuters)
Peak Resources Ltd is developing the Ngualla Rare Earth Project in Tanzania is a recent discovery and is the highest grade of the large undeveloped rare earth deposits. Fundamental geological aspects offer distinct advantages for development over other rare earth projects. These include the large size of the deposit, outcropping, high grade mineralisation amenable to open cut mining with low strip ratios, favourable mineralogy amenable to a relatively simple, low cost processing route and extremely low uranium and thorium levels. Located in southern Tanzania 147 kilometres from the city of Mbeya on the edge of the East African Rift Valley, Peak’s Ngualla Project is centred on the Ngualla Carbonatite. The maiden Ore Reserve estimate for the Ngualla Project was announced on the 19th March 2014 and is 20.7 million tonnes at 4.54% REO (total rare earth oxide plus yttrium).
- Mantra Tanzania Limited will soon begin uranium extraction at its Mkuju River project after it received an environmental impact assessment certificate, Tanzania's The Guardian reported on Saturday June 8 2013. Through local and foreign experts, the government has taken measures to ensure there is no environmental harm from mining activities, said Minister for Energy and Minerals Sospeter Muhongo. Mantra will drill for uranium during the dry season so that lorries can travel on dry roads, Mantra Executive Director Asa Mwaipopo said. The Mkuju River project is expected to attract $1 billion (1.6 trillion shillings) of foreign direct investment to Tanzania over the life of the mine, and to generate some $640 million (1 billion shillings) in direct and indirect cash flows. European Union Ambassador Filiberto Ceriani Sebregondi has said the EU will work with the Tanzanian government to ensure uranium extraction is properly conducted.
- Douglas Lake Minerals Inc. announced it has successfully acquired four Tanzanian uranium properties that cover an area of approximately 500 square kilometres. Two of the properties are located in Northern Tanzania in the Babati region. Initial reports provided by DLKM's geological consultants, Geosource Explorer, have determined that these two deposits are 'surficial'. The other two properties are located in the Njombe District in southern Tanzania. Initial reports by Geosource Explorer indicate the southern deposit geology is similar to that of the Rössing Deposit in Namibia.
- Goldstream Mining NL. Four new tenements covering a total area of 1,885km2 have been offered to Goldstream by the Tanzanian Ministry of Energy and Minerals. Historic drill intercept of up to 2,3 kg/t U308 in a ‘calcrete’ environment, occur on the company’s Bahi tenements in Central Tanzania. Drainage geochemical surveys conducted by Goldstream over its tenements in Southern Tanzania have identified anomalous coincident uranium and lead anomalies.
- Uranium Resources plc (AIM:URA) has acquired four uranium prospecting licences, covering an area of approximately 2,500 km2. The area has promising geology with the German company Uranerzbergbau GmbH identifying the area as prospective for uranium during reconnaissance exploration between 1978 and 1982. Three of the licences are located in the Mkuju River area in southern Tanzania, an area recognised by Uranerz as one of the two most important uranium targets in Tanzania. The fourth licence, the Makutapora prospect in Central Tanzania, targets uranium in calcrete. Western Metals Limited has entered into a farm-in agreement with Uranium Resources.
- Uranium Hunter Corporation has an agreement with Trimark Explorations, on behalf of its wholly owned subsidiary Gambaro Resources, to earn up to a 100% interest in a gold/uranium property located in Njombe and Songea Districts, Tanzania.
- International Gold Mining Limited (TSX VENTURE:IGL) has joint ventured into two tenements at Bahi Swamp, consisting of one granted prospecting licence, and one application, totalling 1,821 square kilometres of ground. The Bahi Swamp catchment area is a dry lake covering over 1,000 sq km, and incorporates an extensive closed drainage system that has developed over 27,000 sq km of weathered Archaean granites.Uranium accumulation within the Bahi catchment system has been recognised since the 1950's when uranium mineralisation was first intersected in a drill hole located near the centre of Bahi Swamp. Recent positive exploration results announced by Uranex NL from the Bahi 'C1' prospect have reconfirmed the potential of the Bahi Swamp catchment area to host significant calcrete / playa, as well as roll front style uranium deposits. The two tenements abut the western boundary of Uranex NL (UNX-ASX) project with assays from vertical channel samples reported to include 1.5m @ 2.4kg/t U3O8, 2.75m @ 1.33kg/t U3O8, and 2.0m @ 1.4kg/t U3O8.The Company has also entered into a joint venture over a granted prospecting licence covering an area of 43 sq km at Singida, considered prospective for gold, uranium and diamonds.
- Western Metals Limited (ASX: WMT) is drilling the Mtonya Project, with high grade uranium over a strike length of 4 km and announced the discovery of two new uranium prospects within its Tanzania exploration area.Surveys from the regional helicopter supported field reconnaissance programme carried out in November 2007, has resulted in the discovery of two new important mineralized systems, Foxy and Eland, in the Ruvuma project area. The prospects are located approximately 60 km south-east and 110 km south-west of Mtonya respectively.Foxy Prospect - mineralisation at Foxy is related to a hematised sandstone bed exposed over an area of approximately 0.5km2. Counts up to 20,000 counts per second (cps) were found in association with the abundant yellow secondary uranium mineral, uranophane. A grab sample taken from the eastern edge of the anomaly returned an assay result of 13,400 parts per million (ppm) U3O8.Eland Prospect - mineralisation is associated with a banded, leuco gneiss. WMT geologists located an anomalous area of approximately 0.6km2 with hotspots up of up to 4,000cps. Grab samples collected from the area returned assay results of 141ppm U3O8, 440ppm U3O8 and 1,080ppm U3O8.The discovery of a new type of uranium mineralisation in basement rock in SW Tanzania is extremely encouraging. The potential presence of this type of mineralisation opens up a number of possibilities and warrants the re-evaluation of a number of highly significant airborne radiometric anomalies that were previously downgraded and dismissed as anomalous basement.
- Atomic Minerals Ltd has signed a letter of intent with Geo Can Resources Company Ltd. to acquire up to a 90% interest in over 2800 sq. kilometers of potential uranium enrichment in southwestern Tanzania. It is located in the same region as properties held by Paladin Resources (Malawi), Denison Mines and Western Metals.
