LIM files Technical Report on its DSO iron ore projects in Labrador and Quebec
Anglesey Mining plcâs 41% owned associate Labrador Iron Mines Holdings
Limited (âLIMâ) or (the âCompanyâ) (TSX: LIM) reports the filing on SEDAR
(the official website for information on Canadian public companies) of a
Technical Report addressing the ongoing exploration and development of its
DSO iron ore projects on the Companyâs various deposits in Western Labrador
and North Eastern Quebec.
The Technical Report has been prepared as a result of additional
metallurgical testwork and process design and following the completion of
the construction of the Silver Yards processing plant facility and other
associated infrastructure and the commencement of initial mining at the
James deposit.
The Report proposes various additions to the Silver Yards plant as a result
of the recent metallurgical testwork and discusses a preliminary production
schedule for the current resources together with the future development of
the further twelve deposits containing historic resources through to the
year 2028.
The Report also makes recommendations for further exploration on
the various deposits and other associated work required to advance the
deposits towards production.
The Technical Report notes the recent new resource estimates for the Houston
and Denault deposits as a result of additional exploration drilling carried
out in 2010.

LIM has now defined 37 million tonnes of current NI 43-101 compliant direct
shipping hematite iron ore resources at the first four deposits that it
intends to develop. In addition, a further 125 million tons of historical
resources exist on LIMâs other properties that were defined by IOC during
their historical operations in the area.
The current resource estimates for the James, Redmond, Houston and Denault
deposits are summarized in following table.

The historical resources referred to in this document are based on work
completed and estimates prepared by the Iron Ore Company of Canada (âIOCâ)
prior to 1983 and were not prepared in accordance with NI 43-101. These
historical estimates are not current and do not meet NIÂ 43-101 Definition
Standards.
A qualified person has not done sufficient work to classify the
historical estimate as current mineral reserves. These historical results
provide an indication of the potential of the properties and are relevant to
ongoing exploration.
The historical estimates should not be relied upon.
Preliminary Development Schedule
LIM intends to develop all these resources in five separate stages. The
first four stages will see the various deposits treated in three
beneficiation plants, to be built adjacent to several of the deposits that
comprise the Central, South Central and North Central Zones.Â
Stage 1 incorporates the James and Redmond deposits at the Silver Yards
plant which is now constructed and where production is expected to commence
in the spring of 2011.
This stage also contemplates the treatment of other
nearby deposits (Central Zone) and is expected to continue until 2021.
Stage 2 contemplates a new plant at the Redmond Mine site initially treating
Houston ore, commencing in 2013, and will continue until about 2022 (South
Central Zone).
Stage 3 is based on a third plant near Howse, (North Central
Zone) which will treat ore from Barney and Howse, commencing in 2015 and
will continue until about 2028.
Stage 4 treating ore from the southern
deposits Sawyer Lake and Astray Lake (South Zone) through the Redmond plant
will continue until about 2028. Stage 5 based on ore from the Northern
deposits (North Zone) will follow the first 4 stages.
Overall production of saleable iron ore product is planned to commence at
around 1.5 million tonnes annually (mta) in 2011 and will build up to about
5 mta by 2015 and, based on the future development of all other deposits,
stages 1 to 4 will continue at this level until about 2028 when stage 5 is
expected to commence.
Only the James and Redmond Deposits and the Silver Yards plant have
completed environmental assessment and permitting.
Further environmental
assessment and permitting will be required for all the other deposits.
Detailed mine design and metallurgical testwork has been carried out on
those deposits that will form the basis of production for the initial years
but further exploration, testwork and design is required for all the
remaining resources.
A Feasibility Study has not been completed on any of
these Projects.
The first plant at Silver Yards and mine construction at James are
essentially complete and initial production is expected in the spring of
2011.Â
Plant Upgrade and Expansion
Based on the current testwork, a program of plant enhancement on the Silver
Yards plant is now planned for 2011 and 2012 with the objective to increase
both the plant throughput and recovery.
The current Silver Yards plant installation (Phase I) consists of a washing
and screening plant to produce lump and sinter fines.
The plan for the first
year is to only wash and screen the higher grade blue ore material, while
higher silica blue and yellow ore will be stockpiled for later treatment.
It is intended that the Silver Yards plant will be upgraded and expanded to
improve recoveries, treat lower grade and higher silica ores and increase
throughput and output.
Phase II will consist of the installation of a fines recovery system and pan
filter. This installation will be completed during the summer of 2011 and
should commence operation in September 2011.
Phase III of the Silver Yards Plant will be the installation of an
additional line which will increase the plant throughput capacity and
improve recoveries.Â
This work is currently being planned and will entail the installation of
jigs to upgrade the final products and the installation of a magnetic
separation stage on the slimes fraction to produce ultra-fines.
Testing and
design of the Phase III expansion is currently in progress and, dependent on
the results of that program, the Phase III expansion should be installed for
operation in mid-2012. The additional line when installed will initially
be used to process the higher silica ore and the yellow ore will also be
processed when the equipment in Phase 3 is fully installed.
South Central Zone
The South Central Zone comprises the Houston and Malcolm deposits. The
Houston deposits located in Labrador some 20kms south-east of Silver Yard
currently comprises 19.5 million tonnes of compliant resource.Â
It was originally planned to treat Houston ore at the Silver Yards plant but
the increased Houston resource suggests that a new stand-alone plant to
treat Houston and other nearby deposits should be constructed. Subject to
completion of environmental assessment and permitting, this plant is now
planned to be built adjacent to the site of the currently permitted Redmond
mine and to commence production in 2013.
The Houston deposits remain open and an additional drill program will take
place in 2011 with the aim of increasing the size of these deposits and
enhancing the resource estimate.Â
Capital Costs Estimate
The additional capital costs for the Silver Yards plant projects are
estimated to be $3 million in 2011 for additional processing equipment to
improve fines recovery and approximately $35 million in 2012 for plant
expansion and enhancement.
The initial capital cost of the Houston Mine Project for mine site
preparation, overburden removal and road construction is estimated to be
approximately $5 million in 2012/2013.
The capital cost of the new Redmond Plant is estimated to be approximately
$35 million in 2012/13 based on the actual cost incurred by LIM on the
construction of the Silver Yard plant but modified to incorporate the single
line design now planned for the Redmond plant.
An additional $8 to $10
million is estimated for the cost of re-laying the Redmond rail spur line.
These cost estimates are subject to final permitting and detailed
engineering and design.
Operating Cost Estimates
The average operating costs for the James-Redmond Silver Yards Project are
estimated to be in the range of approximately CAD$50 per tonne, with all
mining and processing activities carried out by contractors, and with rail
transportation and port handling costs collectively accounting for
approximately half of the total operating costs. The year 2011 is
considered to be a start-up year and initial unit operating costs are
expected be about 10% higher than average.
