Kalia Mine Resource

 

Highlights:

 

·; 74% increase in JORC upgradeable oxide material (from 111mt at 38% Fe to 193mt at 38.6% Fe)

·; Oxide material can be readily beneficiated using a standard gravity process to produce 70.1mt of saleable 58% Fe oxide product (previously 43mt at 58% Fe)

·; An additional Supergene BIF inferred JORC resource of 92.5mt at 36.5% Fe of a friable and weathered material

·; Preliminary testwork indicates the Supergene BIF ("SBIF") is readily upgraded using standard magnetic recovery processes to an average grade of 63.4% Fe, with an average recovery of 40%

·; Oxide and SBIF resource identified on 5.8 km2 of Kalia's 55 km2 surface oxide potential

·; Surface oxide will be part of the magnetite pre-strip prior to magnetite production

 

Bellzone Mining plc (AIM:BZM), is pleased to announce a 74% increase in the inferred JORC oxide resource at its 100% owned Kalia Mine Project in Guinea, West Africa. The resource has been increased from 111mt grading at 38% Fe to 193 million tonnes grading 38.6% Fe.

 

The Kalia Mine Project has a current total iron ore resource of:

Infill drilling has extended the high grade zones and depth extensions of the oxide material. The ongoing metallurgical testwork programme is focused on flowsheet optimisation and providing additional confidence in the product outcome.

The newly identified SBIF is a partially oxidised transition zone located above the magnetite JORC zones and below the surface oxide JORC zone. This 92.5mt resource is friable and initial metallurgical testwork has shown the material to readily upgrade to a product with an average grade of +63% Fe. The average recovery achieved is 40%.

The two products that can be developed from the oxide and SBIF zones have provided the Company with an opportunity to assess producing a blended product. Current testwork has indicated a blend of 30% SBIF product and 70% oxide product will provide a blended product that will meet market requirements.

The ongoing testwork programme will continue to further refine the product qualities and blend ratios to ensure a quality product will be produced from the Kalia resources.

The Company's ongoing oxide development plan continues to target 1.5 billion tonnes (+0.6 billion tonnes or 20 years of saleable oxide product) of oxide resource from five key target areas comprising 63% of Kaila's 55km2 surface oxide potential. The Company is targeting 200 - 250 million tonnes of resource (10 years of oxide production) for inclusion in the Definitive Feasibility Study.

 

Nik Zuks, Chief Executive Officer, commented: "Today's Kalia JORC oxide increase has been established only a matter of months after we announced our maiden oxide JORC resource in May 2011. This 74% increase in our oxide resource and the addition of the high grading supergene BIF product, which has been established on 10.5% of our target 55km2 surface oxide potential, continues to underpin the Kalia oxide product potential. The flexibility to blend these products to produce a high quality product continues to increase the value of the project outcomes. I am confident our ongoing oxide resource development programme will continue to deliver as expected."

About Bellzone Mining Plc

 

Bellzone Mining plc is an exploration and resource development company with iron ore and nickel / copper permits in the Republic of Guinea, West Africa.

 

Kalia Mine

The Company's flagship project, the Kalia Mine Project, is planned to commence production in 2014 and be producing iron ore and iron ore concentrate at a rate of 50 million tonnes per annum in 2018. The Kalia Mine Project has a 3.74 billion tonne magnetite JORC resource and an oxide JORC resource of 193 million tonnes. A Supergene BIF JORC resource of 92.5 million tonnes at 36.5% Fe has been delineated and shows the potential to upgrade to produce 37 million tonnes of 63% Fe material. The oxide and Supergene BIF resources have been established from just 10.5% of the 55km2 of the mapped surface oxides on the Kalia permit. Drilling results and internal estimates indicate that the Kalia Mine Project has the potential to host more than 10 billion tonne of magnetite and 2 billion tonne of oxide.

CIF - Project, Financing & Infrastructure Partner

Bellzone has a Definitive Agreement ("Agreement") with China International Fund Limited ("CIF"). The Agreement gives CIF right of first refusal to purchase the Kalia Mine Project's production at market rates and CIF commits to providing Bellzone commercially related funding for the development of the Kalia Mine Project.

The Agreement contains CIF's commitment to fund and build commercially operated rail and port infrastructure that will enable Bellzone to export production from the Kalia Mine Project. The infrastructure is being developed by Kalia Horizon Minerals Pte Limited, an entity that is 90% owned by CIF with Bellzone having a 10% carried interest. The Agreement provides for Bellzone to be the lowest cost user with permanent priority access.

Forécariah JV

Bellzone and CIF also have fully funded a joint venture to undertake the accelerated exploration and development programme at CIF's Forécariah iron permits that lie between 30 and 80 kilometres from the Guinea coast. Production is scheduled to start in Q1 2012 with an initial production rate of 3-4 mtpa of oxide ore, ramping to a rate of 10 mtpa in 2013.

Other activities

Bellzone has completed a mapping and surface sampling programme identifying highly prospective targets at its Sadeka Nickel/Copper Project. A VTEM aerial survey is currently being conducted to further define areas for a targeted drilling programme.

Bellzone has acquired the rights to buy 70% of Compagnie Miniere de L'Ouest Africain SA, incorporated and holding tenements in Mali. The company is undertaking geological studies on the tenements which are prospective for iron ore before making an investment decision.

 

GLOSSARY

"Al2O3"

Aluminium Oxide

"BIF"

banded iron formation

"Fe"

Chemical symbol for Iron

"Indicated Mineral Resource"

as defined in the JORC Code, is that part of a Mineral Resource which has been sampled by drill holes, underground openings or other sampling procedures at locations that are too widely spaced to ensure continuity but close enough to give a reasonable indication of continuity and where geoscientific data are known with a reasonable degree of reliability. An Indicated Mineral Resource will be based on more data and therefore will be more reliable than an Inferred Mineral Resource estimate

"Inferred Mineral Resource"

as defined in the JORC Code, is that part of a Mineral Resource for which the tonnage and grade and mineral content can be estimated with a low level of confidence. It is inferred from the geological evidence and has assumed but not verified geological and/or grade continuity. It is based on information gathered through the appropriate techniques from locations such as outcrops, trenches, pits, workings and drill holes which may be limited or of uncertain quality and reliability

"JORC"

Joint Ore Reserve Committee. An internationally recognised method of classifying mineral resources

"Magnetite"

An oxide mineral (Fe3O4). The most common ferromagnetic mineral and principal ore

"Measured Mineral Resource"

defined in the JORC Code, as that part of a Measured Mineral Resource for which the resource has been intersected and tested by drill holes, underground openings or other sampling procedures at locations which are spaced closely enough to confirm continuity and where geoscientific data are reliably known. A Measured Mineral Resource estimate will be based on a substantial amount of reliable data

"Mineral Resource"

a concentration or occurrence of material of intrinsic economic interest in or on the earth's crust in such a form that there are reasonable prospects for the eventual economic extraction. The location, quantity, grade, geological characteristics and continuity of a mineral resource are known, estimated or interpreted from specific geological evidence and knowledge. Mineral Resources are sub-divided into Inferred Mineral Resources, Indicated Mineral Resources and Measured Mineral Resources

"Oxide"

ore containing oxides of iron, chiefly haematite, goethite and magnetite

"P"

Chemical symbol for Phosphorous

"Schist"

a group of medium-grade metamorphic rocks, chiefly notable for the preponderance of lamellar minerals. Schist is characteristically foliated, meaning the individual mineral grains split off easily into flakes or slabs

"S"

Chemical symbol for Sulphur

Supergene BIF

BIF material that is weathered and more friable with an enriched Fe % compared to BIF in the magnetite resource.
