Description
Altura Mining Limited has been listed on the ASX since 8th January 2001, when it raised $3.5 million for development of its Bald Hill tantalite mine.
The Company has exploration and development activities for Iron Ore, Industrial Garnet, Coal, Uranium, Lithium, Tantalum, Base Metals and Gold with a mining services arm providing drilling, geophysical and project development services.
Balline, Western Australia
The Balline mineral sands project is located in the mid-west district of Western Australia between the coastal town sites of Kalbarri and Port Gregory. Altura entered into an agreement for the right to explore for and evaluate heavy mineral (HM) resources at Balline in June 2006 through its subsidiary company Australian Garnet Pty Ltd. Two granted exploration licences (E70/2509 and E70/2546) overlie the project area.
Garnet sand is a hard mineral, free of heavy metals and toxic components and is used as a blast for medium for cleaning steel structures, as well as water-jet cutting and water filtration, among other uses. Garnet is highly sought after and widely used commodity in the industrial blasting and cutting industry and due to its generally inert and non-toxix properties; the worldwide demand for this commodity is growing.
Extensive exploration undertaken by Australian Garnet had identified three zones (Balline North, Balline South and Menari) of significant heavy mineral content at Balline. These zones are present by near-surface Garnet, Ilmenite and leucoxene-bearing strandlines within Cainozoic coastal sand dunes. In excess of 14,000m of air core drilling has been undertaken and in December 2008 independent consultants CSA Australia Pty Ltd and Craigstone Pty Ltd established an initial resource of 30.3 mt @ 7.11% HM classified under the JORC code (ASX Announcement 16 December 2008).
A review of this Mineral Resource was undertaken by AMC Consulting Pty Ltd prior to an Ore Reserve estimate released in August 2009 (ASX Announcement 21 August 2009). The total resource at Balline is reported as 226.9 mt @ 3.7% HM (8.4 mt HM) with a probable Ore Reserve of 65.5 mt @ 5.7% HM (3.7 mt HM). The main products being targeted from the resource are Garnet, Pseudo-Rutile, Ilmenite, Rutile and Zircon.
Pilbara, Western Australia
The Pilbara Project consists of seven target areas with historical tantalite and tin production. Ten Exploration Licences totaling over 610 sq km comprise the project with two granted tenements E45/2287 and E45/2312. The initial focus of the region was the Pilgangoora tenement E45/2287 where anomalous rock chip and soil samples up to 390ppm Ta were returned with a number of results in excess of 50 ppm Ta.
Haddington's immediate strategy in the Pilbara is to assess Pilgangoora E45/2287 and E45/2312 Woodstock for all mineral commodities as well as hard rock pegmatite resources. A swarm of pegmatite veins run parallel to the granite contact with the greenstones of the Warrona Group. This tenement covers the western alluvial covered portion of the field with significant quantities of alluvial/eluvial tantalite and tin previously mined from these narrow pegmatites.
The work program for the Pilbara district will involve generative programs for gold and basemetals within E45/2287 and greenstone terranes within E45/2312.
The orderly progress of the applications through the DOIR (Department of Industry and Resources) grant process will enable Haddington to undertake a comprehensive data review and first pass geochemical exploration to generate prospective drill targets.
In May 2008 Haddington entered into an Option Agreement with Atlas Iron Limited which allows Atlas to target channel iron deposits (CID) within the tenements display on the map to the right. Atlas is proposing to undertake extensive drilling of the titles when granted.
Smithfield, Western Australia
E70/2254 Smithfield , situated 20 km SW of Greenbushes in Western Australia,lies in the South West province of the Yilgarn Block, within the Balingup Metamorphic Belt.
The Smithfield pegmatites fall along the major Donnybrook- Bridgetown shear zone which also controls the mineralization at Greenbushes. Numerous tin, tantalum and niobium anomalies have been noted and well as historical production from Donovans Find, Willow Springs and Native Dog Gully. Exploration by Greenbushes Ltd revealed a broad mineralized zone extending 5km from Willow Springs with small pegmatites up to 35m in width and significant Ta and Nb stream anomalies.
The tenement is presently under option to Hampton Hill(Managers)/Teck Cominco/BHP Billiton, joint venture, who are exploring for gold and base metals within the Balingup Gneiss Complex. Activities completed include helicopter EM survey, fixed loop EM, surface geochemical surveys and diamond drilling. The Operators are earning a 75% interest in the Smithfield Prospect by spending $500,000 on exploration.
Two drill holes have been completed to test two conductors identified by a helicopter-borne geophysical survey within the licence.
One hole intersected 7m of semi-massive to stringer pyrrhotite-pyrite mineralization from 101m with weakly anomalous values of copper, zinc and gold. The other hole intersected disseminated pyrrhotite and pyrite mineralization over an interval of 30m, commencing at 235m, returning anomalous zinc values.
Recent laterite soil sampling has defined moderate laterite. Hampton Hill, as Managers, are continuing the program to test these and previous anomalies.
Finniss Range, Northern Territory
MoThe Bynoe pegmatite field is 70km in length and 15km in width. All pegmatites are believed to have been derived from the Two Sisters Granite (Ahmad 1995), which is considered to dip to the east under the Burrell Creek Formation, below the exposed pegmatites. The pegmatites typically occur in clusters, and six pegmatite groups are recognised within the Bynoe field; The Kings Table, Observation Hill, Walkers Creek, Labelle, Leviathan, River Annie Group.
First pass exploration for rare element pegmatites conducted on the project area included an extensive soil sampling, rock chip sampling, mapping and RAB drilling program.
Anomalous soil geochemistry and encouraging rock chip results at Sues, Rocky Ridge, A1 and A2 indicate the possibility for rare metal pegmatites in the area. Encouraging results were also received from at least seven parallel, north-easterly trending pegmatite dykes at the Archer prospect (max 1657 ppm Ta, with 42 samples > 100ppm Ta).
The Mt Fitch Copper-uranium resource is located immediately east of the project area within the Rum Jungle Uranium Field. The potential for uranium mineralisation to be located in the south eastern portion of the project area will be tested by reconnaissance sampling and regional EM surveys in the coming 2008 field season.
Haddington’s strategy for the project is to further delineate and prioritize the numerous geochemical anomalies with an extensive rock chip, soil and mapping program over various prospects defined by work during 2006 and 2007.
Targeting of interpreted EM targets beneath 'black soil' horizons will be undertaken with proposed reconnaissance aircore drilling. Comprehensive data review of the recently acquired tenements surrounding the Bynoe tantalum resource will also be completed.
Shoobridge, Northern Territory
The Shoobridge Project is located approximately 160km south southeast of Darwin; approximately 19km west northwest of Hayes Creek. Eight granted tenements covering approximately 345 sq km have potential for uranium, tantalum, gold, iron and base metal mineralization. This project was purchased from private interests in April 2006. Previous operators eg. Dominion Mining, Carpentaria/MIM, Julia have predominantly explored for gold and tantalum in the project area.
Literature review has identified a number of significant uranium targets at the Liberator prospect. Sampling of costeans returned values up to 19m @ 0.12% U3O8 and 9m @ 0.18% U3O8 and correlate to regional airborne radiometric anomalies.
Unconformity and vein type uranium mineralization is considered a prospective target in this region, with small vein-type mines located at Adelaide River, George Creek and Fleur de Lys.
At Liberator, high grade uranium mineralisation was intersected in 07LIBRC006, intersecting 3m@ 6.05% U3O8 from 40m.
Petrographic investigation revealed that the drill intercept contains major developments of uraninite, often as semi massive associations.
Drillhole 07LIBRC001, located approximately 300m to the north, intersected two meters of mineralisation (bright green tobernite), returning 6m@ 1.34% U3O8 from 19m including 1m @ 4.99% U3O8 from 21m.
Close-spaced gravity, nanoTEM and IP surveys are currently underway to interpret mineralised structures and develop exploration models for proposed drilling.
Geochemical sampling has also defined anomalous copper mineralisation at the Two Nick prospect, as well as Pb mineralisation at the Whatleys and Plateau Point prospects. Inital drill testing of these anomalies is proposed for the 2008 season.
Tanami, Northern Territory
The Tanami province is a leading gold producing region with a number of well-known producing and closed open pit and underground mines ie. Callie, Granites, Tanami, Groundrush. The Coyote and Laraginni projects are operating on the Western Australian side of the province.
The prospectivity of the region to host economic uranium mineralisation is also highlighted by The Northern Uranium/Cameco holding in the north, targeting unconformity uranium in the Lower Proterozoic Gardiner sandstone. The Tanami Complex is host to several major granite complexes which may form the heat source and fluid pathways for localising paleochannel/unconformity style uranium mineralisation in the overlying Proterozoic sandstones and later Permian/Recent sediments.
This area also covers unconformably overlying Late Proterozoic and Permian sediments adjacent and probably located over Tanami Complex granites. The potential for uranium enrichment in the finer reduced units and noted Permian coal horizons is a significant exploration target. Uranium channel radiometrics indicate high response in the Permian cover sequence.
Three applications EL26626, 26627 and 26628 (564 blocks, approximately 1800km2) are located along the western extension of the Granite-Callie mineralised corridor as well as the southern extension of the Tanami gold corridor.
These applications are located on Aboriginal freehold and will progress to grant through the Aboriginal Land Rights Act legislation.
Initial proposals include comprehensive data compilation, regional geophysical surveys and reconnaissance geochemical sampling.
Indonesia
The Tabalong Coal Project, located in South Kalimantan, Indonesia, was added to Haddington’s portfolio in September 2007 through the acquisition of Minvest International Corporation.
The project comprises of two Kuasa Perambangan (KP’s) located in the coal bearing area of the Tanjung Formation in the province of South Kalimantan. The KP’s (Mining Permits) are held by PT Suryaraya Permata Khatulisitwa (PT SPK) and PT Suryaraya Cahaya Cemerland (PT SCC) and cover 1,993 and 4,315 hectares respectively.
The two adjacent KP’s cover an area of 63km2 and are located in the Tabalong district. This region of Kalimantan has been the focus on intense exploration for coal, resulting in numerous occurrences of high grade coking coal products as well as high energy thermal coals, both of which can attract premium market prices.
Information gathered at Tabalong indicates a high calorific, low ash and medium to high sulphur coal type. Initial geological interpretation indicates that 2 separate coal sequences extend along the entire strike length of the KP areas. Each of these sequences contains several separate groups of seams.
