LONDON, UK, May 7, 2013 /CNW/ - Afferro Mining Inc.
("Afferro" or the "Company"), the exploration and development
company focused on iron ore in Cameroon, is pleased to announce the maiden
National Instrument 43-101 ("NI 43-101") compliant Mineral Resource
for the Ntem iron ore project ("Ntem").
Highlights:
- A total Indicated Mineral Resource of 39.1 million tonnes
("Mt") at a grade of 34.0% iron ("Fe")
- A total Inferred Mineral Resource of 76.4 Mt at a grade
of 34.2% Fe
- Positive pilot-scale metallurgical testwork indicates a
saleable and high grade product
Luis da Silva,
Chief Executive Officer of Afferro, commented:
"The maiden resource marks an important step
in the development of Ntem. This resource, which has potential to
increase, is of an appropriate size to build a small-scale
operation to drive early cash flow for Afferro. This would take
advantage of Ntem's strategic location, only 80km from the
deep-water port under construction south of Kribi, where a shipping
berth for a small operation should be available from mid-2014. It
is also close to the Kribi gas-fired power station with a projected
output of 216MW.
This MRE follows the release of the
metallurgical results last week, which point to a saleable and
high-grade concentrate at a coarse grind size, with low deleterious
materials, and the Company is now progressing further work to
investigate the viability of the project. The infrastructure
scoping study will be released shortly, and should, in the first
instance, build on the idea of using road haulage to transport the
magnetite concentrate to port, given the project's proximity to the
coast."
Mineral Resource Estimate
The maiden Mineral Resource Estimate has been
managed and prepared by Howard Baker
of SRK Consulting (UK) Ltd. ("SRK") in accordance with the
provisions of NI 43-101. Mr Baker is an independent Qualified
Person as defined by NI 43-101 and its companion policy
43-101CP.
The definitions of Measured, Indicated and
Inferred Mineral Resources, and Mineral Reserves as used in the
report, are as defined in the CIM Definition Standards on Mineral
Resources and Mineral Reserves adopted by the CIM Council.
SRK conducted multiple site visits to the Ntem
Project during the course of the drilling programme. This included
a qualified person site visit, undertaken by Dean McMinn of SRK. Mr McMinn is an independent
Qualified Person as defined by NI 43-101 and its companion policy
43-101CP. A further site visit by Paul
Stenhouse of SRK was undertaken to prepare a detailed
structural evaluation of the project and additional site visits
were undertaken by Colin Rawbone of SRK to ensure that compliance
to all appropriate Quality Assurance/Quality Control ("QA/QC")
procedures were maintained throughout the drilling programme.
The Ntem Mineral Resource Statement is shown
below and is based on a metal price of USD1.4/dry metric tonne unit ("dmtu") for
magnetite fines which is taken from SRK's internal consensus market
forecast data. It should be noted that the results of the
optimisation study undertaken to enable the reporting of the
Mineral Resource Statement are insensitive to metal prices down to
approximately USD0.9/dmtu. The Ntem
project is wholly owned by Afferro.

Notes:
(1) Mineral Resources which are not Mineral Reserves have no
demonstrated economic viability
(2) The effective date of the Mineral Resource is 3 May 2013
(3) The Mineral Resource Estimate for the Nkout deposit was
constrained within lithological and grade based solids and within a
Lerchs-Grossman optimised pit shell defined by the following
assumptions; metal price of USD1.4/dmtu; slope angles of 16º and 41º in the
oxide and fresh material; a mining recovery of 95.0%; a mining
dilution of 5.0%; a base case mining cost of USD1.60/t and an incremental mine operating costs
of USD0.05/t/10 metres ("m") below
the 70 m reference RL and USD0.05/t/10 m above the 70 m reference RL;
process operating costs of USD4.20/t
crushed oxide and USD5.50/t crushed
BIF ore; Oxide processing recovery of 60%; BIF processing recovery
of 88% and G&A costs of USD0.78/t
and USD0.96/t crushed oxide and BIF
ore.
(4) Mineral Resources for the Ntem deposit have been classified
according to the "CIM Standards on Mineral Resources and Reserves:
Definitions and Guidelines (December
2005)" by Howard Baker
(MAusIMM(CP)), an independent Qualified Person as defined in NI
43-101.
Ntem Resource Potential
The Ntem model is open along strike and SRK
recognises that there is potential to increase the Mineral Resource
Estimate by targeting material that falls below the optimised pit
shell but remains potentially economic. This material, based on a
metal price of USD1.4/dmtu is
considered by SRK to be potentially economic, should sufficient
exploration data be collected that confirms the geometry and
continuation of the mineralisation and that enables a classified
resource to be estimated. SRK has estimated that an additional
50 Mt to 150 Mt lies below the
optimised pit shell used for constraining the Inferred and
Indicated Mineral Resources. The potential quantity of tonnes is
conceptual in nature as there has been insufficient exploration or
demonstration of economic viability to report these in the Inferred
Mineral Resource category at the current time. It is uncertain if
further exploration will result in these targets being defined and
reported in a future Mineral Resource Estimate. These potential
tonnages reflect a range of material within SRK's wireframe solid
models outlining the interpreted down dip extent of
mineralisation.
Database Validation
The QA/QC programme for Ntem consists of
alternating the insertion of a blank, standard and duplicate sample
on a regular basis within the sample train. The Company uses
standards with varying grades which are also alternated. All
samples have been assayed at the accredited ALS Minerals in
Ireland and ALS in Johannesburg. SRK found that the results of
the above described QA/QC programme indicate that Ntem's assay
databases were appropriate for mineral resource estimation.
Data Verification
Howard Baker and
Dean McMinn, as Qualified Persons,
completed the verification of data on which the maiden Mineral
Resource Estimate was based. This verification included an
assessment of QA/QC data, sample preparation and assay
methodologies, density data, data inputs and survey data used in
the estimate. Data was validated by using field checks, statistical
methods and evaluating the Company's protocols.
Drilling, Geological Modelling, Resource
Estimation Assumptions, Parameters and Methods
The Company recently completed a 7,400 m
core drill programme on the Ntem (Fe08) property in south west
Cameroon. The drilling confirmed
the occurrence of a northeast-southwest trending magnetite bearing
Itabirite that was discovered after the completion of regional grab
sampling and aerial and ground magnetic surveys within the Ntem
exploration permit area that is 100% owned by Afferro.
The drill programme that has been completed was
designed to target the magnetite Itabirite and overlying oxidized
cap material with 56 inclined drillholes intercepting on average a
40 m thick Itabirite unit.
SRK created a geological model based on the
lithological logging, magnetic susceptibility data and
incorporating the results of the structural study undertaken,
enabling the hanging wall and footwall contacts of the Itabirite
unit to be modelled and a three dimensional solid model to be
created. The oxide cap was modelled using the magnetic
susceptibility data and Loss on Ignition values.
A 5 m composite file was used in a
geostatistical study (variography and Quantitative Kriging
Neighbourhood Analysis, "QKNA") that enabled Ordinary Kriging
("OK") to be used as the main grade interpolation method. The
interpolation used an elliptical search following the predominant
dip and dip direction of the geological domains. The results of the
variography and the QKNA were utilised to determine the most
appropriate search and estimation parameters.
The interpolated block model was validated
through visual checks and a comparison of the mean input composite
and output model grades. SRK is confident that the interpolated
block grades are a reasonable reflection of the available sample
data.
The NI 43-101 compliant technical report will be
filed on www.sedar.com within 45 days of the date of this
announcement.
