Madagascar Mining News
Madagascar is one of the world’s leading producers of sapphire as well as other coloured gemstones including ruby, multi-coloured tourmaline, emerald, amethyst, cordierite, aquamarine and garnet and also plays a significant role in the production of high quality flake graphite. Madagascar is the second largest producer of graphite in Africa accounting for 45% of total output, although production has declined over the last five years by 35%. Madagascar is the third largest producer of chromite in Africa accounting for 0.8 per cent of total output. The country also produces modest amounts of gold, phlogopitic mica, beryl, salt, gypsum and ornamental stone (labradorite, celestite, agate, jasper and rose quartz). Madagascar also has major resources of nickel, cobalt, copper, platinum group metals, titanium, zirconium, uranium, bauxite, iron ore, coal and tar sands. The giant Ambatovy lateritic nickel-cobalt project is to start production in 2011-12 with an annual capacity of 60,000 tonnes of Ni and 5,600 tonnes of Co. A major titanium sands project at Mandena started production in 2009 and will ramp up production to 750,000 tonnes of ilmenite, rutile and zircon per annum by 2012. Later phases of the project have potential to expand production to 2.2 Mt /yr.

- Rio Tinto-Alcan holds the mineral rights to the bauxite deposit Manantenina , near Fort Dauphin. The deposit was initially studied by Pechiney, which was then taken over by Alcan. According to experts, it is possible to produce about 3 million tonnes of alumina per year at full capacity, Due to the energy deficit in the country, it is not considered for the moment, to make on-site processing of alumina into aluminum. An access road will have to be constructed between the mine site and the new port to facilitate export.
- Societe Kraomita Malagasy (Kraoma), which is Madagascar's main chromite producer, produces around 40,000 t/y of concentrates plus 80,000 t/y of lumpy ore from the Andriamana complex, and a further 20,000 t/y from the Befandriana mine.
- Lemur Resources Ltd is a Madagascan focussed coal exploration company incorporated in Australia in November 2010. Lemur is the 100% shareholder of the Guernsey registered company, Coal of Madagascar Limited ("COM") which is the 99% Shareholder of the Malagasy registered company, Coal Mining Madagascar SARL (“CMM”). CMM has an interest in seven mining permits located in the Imalato Coal Basin, the initial focus being the Imaloto Coal Project. This project contains a gross in situ JORC compliant inferred resource estimate of 175 million tonnes, which was defined through an initial two phase drilling program completed in 2008 and 2009. The Imaloto Coal Project is located in the Imaloto Coal Basin, which is the northern-most coal field in the greater Sakoa Basin of South West Madagascar. Lemur will be commencing the Phase III work programme in July 2011, which has a primary objective of better defining the limits of the coal seams and to bring the current inferred resource up to the measured category.

- Canada's Pan African Mining through its operating subsidiary, PAM Madagascar Sarl, holds 10-year research permits covering in excess of 3000 square kilometres in areas deemed prospective for diamond exploration in various regions of the country. The company commenced exploration in 2004 and announced that kimberlite indicator minerals had been recovered from an initial reconnaissance sample taken.
- In 2004, Majescor Resources reached an agreement with De Beers to form a joint venture to explore for diamonds in the cratonic areas Majescor holds rights to in northern and central Madagascar. In 2003 and 2004, De Beers has collected and processed 102 samples totaling 77 m3 in volume from areas of Madagascar selected for their diamond potential. The company spent over C$1,000,000 on the exploration programme and on the evaluation of samples. The company's analysis led to the recovery of 4,378 visually positive kimberlitic indicators, some of which have been confirmed, through micro probing, as having a kimberlitic origin. In 2005 Majescor had found some kimberlite samples, but it turned out to be sterile, however, the company continued to carry out diamond exploration. (Source: MBendi)
Gold in Madagascar
Location and history
The Betsiriry gold district may be considerably larger than indicated in past reports. We note several gold prospects: Ankofoka, Antsiroroka, Antsevakely, Miandrarivo, almost 100 km north-east of Miandrivazo district in what is essentially the same geological environment.
The gold district of Itasy-Tsiroanomandidy is located 50-150 km west of the capital, Antananarivo, and produced 1,260 kg of gold between 1901 and 1921. Numerous vein deposits were worked and rapidly abandoned. Its peak production was in 1904 with 174 kg produced, largely from the Vohinambo deposit.
Throughout the district there are several mentions of auriferous quartzites with magnetite: i.e. Ambohimanoa, Ambohitsivalana, Behana. These are potentially large if low-grade deposits very amenable to modern extraction techniques, particularly if the gold occurs (as has been indicated) as inclusions in the magnetite. IMR is of the opinion that this is well worth investigating.
The prospect is located at only 9 km to the south of Tananarive. It is a very old prospect in several small veins of gold-bearing quartz in migmatites, gneiss and granites. The prospect has been worked by a large trench producing between 1-2 kg gold per year.
This prospect occurs 50 km to the west of the Tsironomandidy village. Its placers were recognised at the start of the century. Two hills, Ankafotra and, above all, Betanimena, show a substratum of auriferous gneiss. Where these have been lateritised they formed local concentrations of very fine gold, with occasional outcrops of auriferous quartz veinlets. In the alluvions of the Ankafotra and Bekopaka rivers gold can occur as pepites (suggesting a goldfield where gold detectors could be usefully employed by individual miners). The forested areas of these alluvions have not been worked.
- Numerous artisanal workings with an estimated production of 3 to 4 t of gold annually.The Dabolava region has been one of the most productive..
The Dabolava region is an area of approximately 600 km2 and is situated on the western edge of the Precambrian in west-central Madagascar. The geology mainly consists of Proterozoic amphibolite facies metavolcanic rocks, inter-layered with minor metasedimentary rocks, crosscut by granodioritic to gabbroic plutons. The country rocks of the granodiorite and gabbroic plutons are composed of 50% amphibolites, 30% quartzofeldspathic gneisses and 20% metasedimentary rocks, mainly carbonates. The amphibolites consist dominantly of
The government of Madagascar invited a shortlist of companies to submit proposals for the development of three known gold deposits: Betsiaka in the region of Ambilobe, and two deposits in Maevatanana in the region of Mahajanga. Deadline for submission of offers was set for end 2007; the three blocks were to be awarded in the course of 2008.
- Pan African Mining Corporation (Canadian, were also active in Zambia, Mozambique, Congo and North Africa) held prospecting permits in 16 areas throughout Madagascar, half of which cover gold prospects. The company comprehensively compiled historical data and was engaged in early stage exploration. In 2006 Pan-African held approximately 4,087 km2 of permits covering three major gold targets (Dabolava, Andavakoera and Andramasina). In 2005, Pan-African reported to have discovered high-grade gold deposits at its western Dabolava concession, a licenced area situated 180 km west-southwest of Anatananarivo. .Pan-African Mining said in June 2005 that it had found high grade gold deposits after the first phase of drilling at its western Dabolava concession. Yields were 32 grams per ton of rock in some places, the company said. (Asia Thai Mining Co. Ltd. ("ATM") and 0819615 B.C. Ltd., a wholly owned subsidiary of ATM, bougt all the shares of Pan African Mining in April 2008.)
- Majescor Resources (Canadian) gold and base metal properties in Madagascar include, in addition to the Besakoa polymetallic VMS Cu-Au-Zn-Ag prospect in Tulear Province, southern Madagascar.: the Daraina property in North Madagascar, where initial surface sampling in August 2006 returned grades of up to 87 g/t gold and 75 g/t silver; the Analalava property, which is host to a series of untested historical Ni-Cu showings, and is completely surrounded by BHP-Billiton claims; and the Ankaramy property which shows potential for both SEDEX-type (Pb-Zn) and epithermal gold-silver. In April 2008, Majescor announced it had entered into a letter of intent with Sunridge Gold Corp. (“Sunridge”), an experienced Africa-focussed gold and base metal explorer, whereby Sunridge can acquire up to a 100% interest in four gold and base properties held by Majescor in Madagascar. Majescor acquired the land package under option to Sunridge from a local Malagasy mining company in 2006. The principal asset of the property package is the Besakoa license located in the Atsimo-Andrefana region of South Central Madagascar. The Besakoa property holds a series of historical sulphide occurrences including the “Main” Besakao polymetallic prospect, Madagascar’s principal volcanogenic massive sulphide (“VMS”) occurrence. The property consists of a block of 144 CDCs covering 56 km2.In January of 2007, Majescor completed a first core drilling program on the main Besakoa prospect. The purpose of the drilling was to confirm and upgrade geological data derived from historical core drilling dating back to the 1950s. Eight holes were drilled and core was recovered to a maximum depth of 78 metres. Iron oxide and/or copper-zinc-bearing sulphides were observed in all eight drill holes drilled, with intersections grading of up to 21.5 m of 0.7% copper, 0.5 g/t gold, 1.1% zinc and 21.4 g/t silver. The Besakoa property area is considered to be an extension of the same basement rocks of the East African Arabian-Nubian shield which hosts Sunridge’s Asmara and Nevsun’s Bisha VMS deposits in Eritrea. Majescor and Sunridge believe that the Besakoa property area may represent a new emerging Neoproterozoic VMS district as there are numerous gossan outcrops on property and surrounding area which appear to be oxidized remnants of underlying VMS style mineralization. The Besakoa property area last underwent systematic exploration during the 1950’s. Since Majescor acquire the property in 2006, the area has seen resurgence in exploration activity. In August of 2007, Uranium Star Corp. (“Uranium Star”) announced it had acquired a 75% interest in the Three Horses property located immediately to the South of the Besakoa property. Exploration work on the Three Horses property began in the fall. Uranium Star reported finding several gossanous boulder occurrences, believed to overlie massive sulphide mineralization, on the property. A helicopter-borne EM-magnetometer survey was also completed. Uranium Star intends to drill the Three Horses Property in 2008. Majescor and Sunridge are committed to moving the Besakoa property forward in 2008. To this effect, the partners have planned a focused ground exploration program for the summer 2008 field season. This program will include reconnaissance and systematic prospecting and mapping, ground geophysical surveying and soil geochemical sampling.
- The main producers are Societe Miniere de la Grande Ileand Establissments Gallois from widespread occuurences along the eatern coast near Tamatave. ( Graphite Technology was incorporated in Pennsylvania on April 27, 2004, following which time Graphite Technology acquired the graphite processing equipment of Applied Carbon Technology (America), a corporation involved in certain processing and sales of graphite. On January 31, 2005, Graphite Technology reincorporated in the State of Delaware. On July 27, 2005, Graphite Technology entered into a purchase and sale agreement with Societe Miniere de la Grande Ile, ("SMGI"), M. Bertil Akesson, owner/operator of theAmbatomitamba Graphite Mine and four contiguous graphite mines located in Madagascar by which Graphite agreed to purchase a 50% common equity interest inSociete Malagasy du Grafit s.a.r.l., a Madagascar limited liability company ("SOMAGRA"), as and at the time that SOMAGRA owns and has rights to operate and develop the Ambatomitamba Graphite Mine and Sahanovo Mine and contiguous surface mines at Ambodihasina, Sandraka,Ambiani and Sahamaloto. On March 26, 2006, Graphite Technology acquired that 50% common equity interest in SOMAGRA. The purchase and sale agreement also provides Graphite Technology the option to purchase the remaining 50% of SOMAGRA less one share at any time within three years of the closing. Prior to closing, all graphite mine claims and mine leases controlled by SMGI, affiliate companies of SMGI, or by Akesson,) The deposits are in a region where lateritic deposits of iron and bauxite also are found. The graphite occurs in highly metamorphosed schists and gneisses that have been weathered deeply to soft, ferruginous clays. The graphitic content of the original rock has been raised through the natural leaching process. The graphite, being resistant to weathering, is found among the weathered residue. The crude ore contains 3%-10% graphite, of which about two-thirds is large flake and one third is fine flake. The nongraphitic portion of the flake product is uniform and consists (after oxidizing) chiefly of a clayey residue with some quartz and a sprinkle of accessory minerals such as mica, zircon, rutile, and epidote. Sulphur compounds are absent and iron is low.
- Energizer Resources Inc TSX:EGZ and Malagasy Minerals Ltd announced on May 1, 2012, results from the Molo Deposit of its Green Giant Project in southern Madagascar. Assays show6.94% carbon over 20 metres, 7.4% over 87 metres, 14.63% over 13.5 metres, 7.27% over 54 metres, 7.92% over 88 metres. Energizer holds a 75% interest a nd acts as project operator on the Joint Venture Property, which surrounds Energizer’s wholly owned Green Giant Graphite-Vanadium Property on three sides. Energizer has identified 17 graphite trends with a cumulative strike length of more than 320 kilometres on the Green Giant and JV properties. Within two weeks the company plans to begin a Molo resource delineation program, which will take an estimated two months to complete. Shortly after drilling begins, DRA Mineral Projects will begin quantifying data for a preliminary economic assessment of the Molo deposit.The Green Giant Property has a vanadium resource of 49.5 million tonnes grading 0.693% vanadium pentoxide (V2O5) indicated and 9.7 million tonnes grading 0.632% V2O5 inferred. Energizer Resources Inc. (TSX: EGZ) (OTCBB: ENZR) (FWB: YE5) announced on 29 August 2012 that it had received additional assays from its recently completed National Instrument (NI) 43-101 graphite resource drill program on the Molo deposit. The Molo deposit is located in the Green Giant Graphite project, and is part of the joint venture (JV) property with Malagasy Minerals Limited in Madagascar. Energizer has a 75% ownership interest and is the operator of the Project. The recently completed drill program will provide the necessary data to complete a National Instrument (NI) 43-101 graphite resource, which will be part of the Preliminary Economic Assessment (PEA) due in Q4 of this year. DRA Mineral Projects, Africa's largest mine engineering, construction and operations firm, is authoring the PEA Study, while Caracle Creek International Consulting Inc. of South Africa is authoring the resource statement. In total, 41 diamond drill holes over 8,450 metres, and 18 trenches over 2,100 metres were completed during the program. The Company has now received assays for the first 9 (of 41) drill holes, and the first 8 (of 18) trenches completed during the course of the recently concluded resource delineation program. Coupled with the 6 diamond drill holes and 1 trench completed during the December 2011 exploration program, this assay data confirms that the Molo has a very large footprint. The Molo deposit exists within a folded sequence over a 2 km strike length. In the north, it is between 50 to 60 metre wide then flares to over 500 metres in width. From this point, the graphite deposit tapers down to a width of approximately 250 to 350 metres. Finally, the deposit splits into two ‘arms' of between 50 and 100 metre widths respectively. Drill and trench data received to date, as well as mapping, prospecting and geophysical surveying, confirms graphite mineralization at surface, and over an area of at least 250,000 m2. Depth of mineralization has been confirmed by drilling in excess of 300 metres. Based on the size of the Molo footprint, as well as the tenor of mineralization found in the 15 drillholes (9 from 2012 and 6 from 2011) and 8 trenches received to date, the Company is confident of delineating a deposit in excess of 100 million tonnes at an average grade greater than 6% carbon (graphite). An assay table summarizing all results is also provided on the Company's website.
- Cline Minining Corporation owns the Bekisopa iron-ore-deposit properties (Bekisopa East) in Madagascar. The BRGM, Madagascar government and the U.N. early data base reports original Beki-East iron deposit at between 25 per cent and 65 per cent averaging 45 per cent, resource 150 million tones, largely magnetite surface ore. Additional airborne survey in 2007 found additional step-out separate mineralized areas (Bekisopa West) which Cline followed up by ground geophysics localizing the important areas for drilling in 2008. The ground geophysics program in late 2007 was also extended to the existing Bekisopa East deposit revealing the presence of an extensive mass which is to be drilled following the wet season in Spring 2008.
- The Chinese group Wisco has been awarded the iron ore deposit Soalala. The iron reserve of the site is estimated at 562 Mt and is capable of producing about 3.5 Mt per year. The deposit is not far from the coast, south of Mahajanga, but road improvements are necessary to make it more accessible. A port site is planned and a power plant; the planned investment by Wisco is expected to exceed 2 billion USD.
- Dynatec Corporation (Canadian, DY.TO) announced on October 30, 2006, the signing of a shareholders agreement for the Ambatovy Nickel Project. Under the agreement, Dynatec has been appointed project operator and will retain a 40% ownership interest. A 27,5% interest in the Project will be held by each of Sumitomo Corporation and Korea Resources Corporation (leading a consortium of Korean enterprises including Daewoo International Corporation, Keangnam Enterprises Ltd. and STX Corporation). SNC-Lavalin Inc. has agreed to acquire a 5% interest in Ambatovy coincident with the closing of the project debt financing. Dynatec will receive US$852 million of financial support from its partners, positioning it to fund its equity requirements for the Project and to meet a significant portion of its guarantee obligations for project debt financing. Ambatovy is among the largest nickel projects under development in the world, with annual design capacity of 60,000 tonnes of nickel and 5,600 tonnes of cobalt. It is anticipated that Ambatovy will be placed near the bottom of the industry cost curve based on expected low nickel production costs. The Ambatovy Project is based on mining two ore bodies that are about three kilometres apart. The Ambatovy and Analamay deposits are both laterite nickel deposits formed by the leaching of the ultramafic portion of a large intrusive complex. The deposits cover an area of about 1300 hectares, with a thickness from 20 to 100 metres (average thickness is approximately 40 metres). More than ninety percent of the deposit is classified as ferralite, some of which is underlain by saprolite. A material type termed low magnesium saprolite (LMS) lies below the ferralite and between the ferralite and saprolite, where the latter is present. Only the ferralite and LMS have been considered in the mine plan. The distribution of the saprolite is erratic; consequently it has been classified as inferred, and is not included in the measured and indicated resource, although its exploitation may prove to be economic. Exploration on the property has occurred in four campaigns: Bureau des Recherches Géologiques et Minières (BRGM) in 1962; GENiM, a mining consortium comprising Anglo-American, Société le Nickel, Ugine Kuhlmann, and BRGM in the early 1970s; Phelps Dodge in the mid-1990s; and Dynatec in 2003 and 2004. A total of 1282 diamond drill holes have been drilled representing approximately 55 000 metres of drilling. In addition, sample pits have been dug and appropriate surface mapping completed. Proven and probable mineral reserves are estimated at 125,0 million tonnes at an average grade of 1,04% nickel and 0,099% cobalt; additional low grade ore is estimated at 39,4 million tonnes at a grade of 0,69% nickel and 0,064% cobalt; this low grade ore is scheduled to be stockpiled then reclaimed and processed at the end of the mine life; average ore grade over the first 10 years of the mine plan is estimated at 1,12% nickel and 0,101% cobalt; the mine life is estimated to be 20,5 years, plus 6,5 years of stockpile recovery, giving a total production plan of 27 years; total recoverable metal over the production plan is estimated at 1,34 million tonnes of nickel and 122 000 tonnes of cobalt. Sherritt International Corporation and Dynatec Corporation jointly announced a transaction on April 20, 2007, whereby under a Plan of Arrangement Sherritt will acquire all of the issued and outstanding common shares of Dynatec for a total value of C$1.6 billion. Sherritt International Corp. of Toronto said in January, 2014 it had reached commercial production at the Ambatovy nickel operations. Located, 80 km east of Antananarivo, the project is a joint venture of Sherritt (40% and operator), Korea Resources (27.5%), Sumitomo Corp. (27.5%) and SNC-Lavalin (5%).
Ambatovy produced its first finished nickel and cobalt in Q3 2012. It produced 5,695 tonnes of finished nickel and 493 tonnes of finished cobalt.
The project includes an open pit and an ore preparation plant at the mine site. Concentrated laterite ore is delivered by pipeline the process plant and refinery on the east coast. The project has an annual design capacity of 60,000 tonnes of nickel and 5,600 tonnes of cobalt with a mine life of 29 years. It is expected to be the world's largest nickel and cobalt producer from laterite ores.

- Madagascar Oil is the current license holder of the Tsimiroro and Bemolanga tar sand deposits in the onshore Morondava Basin of Madagascar discovered in the early 1900s. Tsimiroro is a large heavy oil field at 100-300m depth. The block, with an area of 6,670 km2, is located in NW Madagascar about 100km from the coast. Sixty-one wells have been drilled on Tsimiroro’s 70 km² core area to date. With the use of SAGD the expected recovery factor is estimated to be 55%. The Company is currently executing a pilot project on Tsimiroro. Tsimiroro is also prospective for conventional hydrocarbons. A Tsimiroro sample of 22º API oil was reported in 1988 from a test well in the south of the block.lBemolanga is a bitumen field at 0-30m depth with a reserve of 16.6 billion barrels (9.8 billion recoverable). The Bemolanga block, with an area of 7,175 km2, is located in NW Madagascar about 120km from the coast. Thirteen wells and over 500 core-holes have been drilled from the 1950s to the early 1980s and the surface mining area is defined by less than 40 meters depth to top tarsand. The average overburden in the surface mining area is around 15m, considerably less than average overburden in Canada. Madagascar Oil also has a 100% interest in conventional oil and gas exploration onshore blocks 2103, 3105, 3106, 3107 and a 50% interest in block 3109, where Tullow Oil is the operator.Construction phase of the Tsimiroro Steam Flood Pilot is reaching completion and steam injection into the first wells has commenced. During 2012 the Company drilled 28 wells in the Tsimiroro field: 16 production wells, nine steam injection wells and three observation wells. In addition several water wells and water disposal wells were drilled The Steam Flood Pilot is designed to evaluate the potential production rates and recovery factor that could be achieved through thermal stimulation A 24,000 line km Airborne Gravity Gradiometry survey was conducted across MOIL’s three exploration blocks and an initiative is underway to consolidate all available data to assess the potential for light hydrocarbons

The work programme includes a 6,700 km reconnaissance aerogravity survey to aid the design of a seismic acquisition programme. Tullow signed the PSA for a second licence in Oct 2006. The onshore Block 3111 (Berenty) lies adjacent to, and south of, Block 3109 and covers 9,050 sq km. The agreed work programme for the initial 3-year exploration period includes the acquisition of 200km of 2D seismic and the drilling of a well. This licence requires a presidential decree before it becomes effective.
- Ambodilafa Project (49%- Implats 51%). Jubilee’s 4 kilometres wide by 20 kilometres long Ambodilafa concession is part of an area underlain by mafic-ultramafic rocks. The property is located some 160 kilometres southeast of the Madagascan capital, Antananarivo. Previous regional reconnaissance drilling by others in the area, in 1969, included an intersection of 93 metres of disseminated sulphides, containing pyrrhotite, pentlandite and chalcopyrite. The intersection included a 1,5 metre intercept assaying 2,2% nickel and 0,35% copper. The drill cores were not analysed for their PGE content, but later stream sediment sampling in 1990 defined several drainage catchments in the vicinity of the area drilled, which showed anomalous platinum and palladium values.
- Londokomanana Project. Located 150 kilometres north of Antananarivo with an inferred 22-kilometre total strike length of nickel-copper mineralization over north (Antsahabe) and south (Lavatrafo) Londokomanana. Peak trench values have been obtained in Lavatrafo of up to 4,62 g/t 2PGE (platinum and palladium) plus gold, 1,2% nickel and 0,39% copper. The Company has drilled two boreholes, LAV1 and LAV2 in the Lavatrafo property (south Londokomanana) on targets identified by geophysics and geochemistry. The two boreholes, some 150 metres apart on strike, intersected a very thick -58 metre and 75 metre true widths - multi-metal nickel-copper-platinum-palladium-gold formation at relatively shallow - 27 and 73 metres depth.
- Lanjanina Concession located in the south-central part of Madagascar approximately 180 kilometres ( 258 road km.) south of Antananarivo and covers an area of 156 km2 (15,600 hectares). Previous exploration identified copper, nickel and platinum group elements in geochemical soil samples and one drill hole located copper and nickel mineralization within pyroxenites and to a lesser extent gabbros and amphibolites.
- QIT Madagascar Minerals (QMM), which is 80% owned by Rio Tinto and 20% owned by the Government of Madagascar, has built a mineral sands mining operation near Fort-Dauphin at the south-east tip of Madagascar.
- World Titanium Resources is developing the Tier 1 Toliara Sands Project north of the port of Toliara in south-west Madagascar. The Ranobe Mine is projected to produce 407,000tpa of ilmenite and 44,000tpa of zircon rich concentrate per annum over an initial 21 year mine life. This first phase of development utilises around 17% of the 959 million tonne of Mineral Resource defined at Ranobe. The overall THM grade of 6.1% for the Ranobe Mineral Resource is high by minerals sands industry standards and the initial Ranobe mine plan focuses on an Ore Reserve of 161 million tonne averaging 8.2% THM, resulting in one of the highest in-situ ore values in the sector. With no overburden and very low slimes (<5%) simple dry mining can be utilised. The heavy mineral at Ranobe consists predominantly of ilmenite making up approximately 90% of the final products. The project also benefits significantly from the presence of much higher value zircon and rutile which, as a zircon rich concentrate, contribute about 10% of the product volume and around 45% of the projected revenue. The ilmenite and zircon rich concentrate can be easily separated from the ore utilising standard equipment and existing infrastructure can be leveraged to minimise the initial development capital. World Titanium Resources has a total exploration target of more than 4,700 million tonne in the Toliara Sands Exploration permits at Ranobe, Ankililoaka, Basibasy and Morombe, including the 959 million tonne at 6.1% THM Mineral Resource at Ranobe.
Uranium mineralization occurs in the sediments of the Morondava Basin of western Madagascar, which consists of Karoo Supergroup continental sediments.
- Pan African Mining Corporation announced that it has been granted 36 additional research permits for uranium exploration in Madagascar. The permits were issued to the company’s subsidiary PAM Atomique Sarl (Pama), which is 20% owned by the Malagasy state. Pama’s uranium exploration programme is ongoing in the Antsirabe and Tranomaro Zones as part of the company’s joint venture (JV) with L’Office des Mines Nationales et des Industries Strategiques, a State agency. By virtue of the new permit grants, Pama’s overall uranium licences in Madagascar now number 46 research permits. The French Commissariat a l’Energie Atomique (CEA) exploited uranium from the regions of Folakara and Tranomaro during the period from the late 1930s through the 1950s, with systematic exploration of Madagascar for radioactive materials being undertaken to 1966 in detailed regional studies that outlined several uraniferous areas. In 1976, the newly created Omnis resumed exploration of the more promising CEA discoveries with technical advice and funding from the International Atomic Energy Agency and associated agencies. Pama is carrying forward such prior work as well as implementing innovative programmes conceived by its geological team working with Omnis.
- Cline Mining Corporation has taken over UMC Energy plc, who has an 80% interest in URAMAD S.A., a Madagascar uranium exploration company. URAMAD S.A. is a private Madagascar uranium exploration company in which the Madagascar Government Agency OMNIS also holds a 20% interest. The URAMAD Morondava Uranium Project covers an area of 9,993.75 square kilometers in the Morondava Basin of western Madagascar, which is filled with Karoo Supergroup sediments. The uranium properties were earlier held by Cogema of France which carried out extensive exploration work, with additional work being carried forward by the United Nations Development Programme and OMNIS. URAMAD has obtained the databases from this work which include an extensive earlier airborne survey (some 7,000 radioactive anomalies) and 83,000 metres of drilling in 790 drill holes with indicated uranium values and visible uranium mineralization. URAMAD is presently undertaking an exploration program on the property including diamond drilling and radiometric airborne surveys.
- Pencari Mining Corporation (TSX VENTURE:PMC) is exploring the Ambatofosy uranium property in central Madagascar. Positive uranium values from samples were obtained along the entire 3000 metre trend of uranium bearing pegmatite. A total of 135 soil samples were collected as part of the regional mapping program, with uranium values ranging from 10 to 780 ppm uranium returned from throughout the 3000 metre trend.Continuing geological mapping and trenching programmes across the Ambatofotsy prospect will run in conjunction with Pencari's regional trenching, geochemical and geophysics programmes currently underway across the Itea gold project.Uranium mineralization at Ambatofotsy is associated with an unusually large pegmatite complex. Mineralization of potential economic interest is reported to include betafite (a high uranium, columbium-tantalum mineral) and columbite-tantalite (columbium-tantalum minerals). Both minerals are important sources of tantalum, a high-tech metal used in electronics.The initial assessment at Ambatofosy was performed by OMNIS (Office Nationale des Mines et des Industries Strategiques), a Madagascar extra-governmental agency that aids the mineral exploration industry by performing geological services that include geological mapping, trenching and soil sampling.
