Legend Mining Limited (ASX:LEG) Cameroon Iron Ore Project Rockchip Results
Results from rockchip float samples of massive magnetite were the highlight results from the 72 assays received to date.
Since the arrival in Cameroon of Exploration Manager Mr John Stockley, on 4 February 2010, a team of six Cameroon geologists have been recruited and a field camp established 3km outside the Eseka township.
Legend Managing Director Mr Mark Wilson said "It is pleasing to have recruited our team and established our camp within the first 60 days of our ownership of the project. The early results, especially of the massive magnetite samples are particularly encouraging. We are now looking to establish a better understanding of the geology of the Eseka Prospect to be able to confidently plan our first drill programme".
"Our Cameroon subsidiary, Camina SA, is now for all intents and purposes close to a fully functioning exploration company" he added.
1. Eseka Prospect
Exploration has been focussed on the Eseka area and included establishing gridlines over the prospect at 400m spacing to assist geological mapping and rockchip float sampling. Geological mapping, geochemical sampling and trenching activities are ongoing and critical to advancing the geological knowledge of the prospect in conjunction with the aeromagnetic data.
A field exploration camp has been established in the northern part of the prospect to aid field activities and logistics. Environmental approvals and base line studies with community consultation is underway in the Eseka region in preparation for future drill rig access.
Results from a total of 72 non-systematic rockchip float/grab samples have been received from Eseka, of which 60 relate directly to iron exploration. An additional 91 rockchip float/grab samples have been submitted for analysis with results pending.
The rockchip samples fall into three broad categories based on rock type and associated assay results; 1) massive magnetite, 2) goethitic/limonitic material after itabirite, and 3) weathered itabirite with variable iron/silica content.
The massive magnetite group is characterised by high iron values between 65-69% Fe with associated low silica, alumina, phosphorus and loss on ignition (LOI) values. The goethitic/ limonitic group has an iron range of 50-63% Fe with varying levels of silica, alumina, phosphorus and LOI. Iron values of the weathered itabirite group have a range of 30-47% Fe (average 39% Fe) with associated silica ranging from 11-51% SiO2 (average 39% SiO2), which is typical for itabirite bodies.
2. Ngovayang Regional Exploration
Final processing of the aeromagnetic and radiometric data, including the infill flight lines, over the entire Ngovayang District has now been completed. The infill flight lines have provided addition detail over the magnetic features allowing better definition/resolution for ground follow-up.
The identification of numerous large/strong coherent magnetic features by the aeromagnetic survey highlights the iron prospectivity of the Ngovayang District. To assist with iron mineralisation targeting, a project wide litho-structural interpretation of the aeromagnetic data is being undertaken to provide additional geological framework. Processing of Landsat data utilising various "filters" to highlight areas with elevated iron content will also be used in conjunction with the aeromagnetic and radiometric data to identify targets.
3. Mayo Binka
The aeromagnetic/radiometric survey was completed over the Mayo Binka tenement with a total of 3,177 line km flown, see Figure 3. Magnetic features were identified in the central eastern portion of the tenement associated with an area with known outcropping massive magnetite/hematite. Previous rockchip sampling of this outcropping massive magnetite/ hematite and associated itabirite units returned iron values ranging from 55-67% Fe. Further ground reconnaissance is required to fully assess the significance of the features.
Legend currently holds interests in an iron ore Project in Cameroon, West Africa, and three Projects in WA, namely, Pilbara, Gum Creek and Mt Gibson.
The Cameroon Project (iron ore, gold) comprises granted exploration permits and applications covering an area of approximately 3,900km2. Discovery of 50Mt of direct shipping ore (DSO) is the primary target, however itabirite ore (lower grade but potential very high tonnage) will also be targeted. The southern project area has the added advantage of being well served by access infrastructure including rail and road networks to and from the port city of Douala.
The Pilbara Project (iron ore, nickel-copper, zinc-copper) comprises 686km2 of tenure in the West Pilbara, all within 50km of Karratha. As well as the magnetite potential associated with BIF of the Cleaverville Formation, Legend has identified 14 priority base metal drill targets from Versatile Time-Domain Electromagnetic (VTEM) surveys.
The Gum Creek Project (iron ore, nickel-copper-platinum group element) is located 640km northeast of Perth in the Yilgarn Province. The Woodley region contains a 22km BIF unit with the potential for a significant tonnage of magnetite. The project is also considered prospective for both intrusion-related (Ni-Cu-PGE) and komatiite flow-related Ni-sulphide mineralisation.
The Mt Gibson Project (zinc-copper-gold) is located 290km northeast of Perth in the Murchison Province. Mt Gibson operated for 12 years as a gold mine from 1986 following the discovery of gold in surface laterite. The operation produced 870,000 ounces of gold from 16.5Mt of ore at an average grade of 1.68g/t. Legend, through a study conducted in 2006 by Dr S Carras of Carras Mining Pty Ltd, estimated the residual gold Mineral Resource (Indicated and Inferred) to be 8.7Mt at 1.98g/t gold for 559,000 ounces (see 2006 Legend Annual Report).
