LUNDIN MINING REPORTS 2011 RESERVE & RESOURCE ESTIMATE


Toronto, September 01, 2011 (TSX: LUN; OMX: LUMI) Lundin Mining Corporation
(“Lundin Mining” or the “Company”) today reported its Mineral Reserve and
Resource estimates as at June 30, 2011. Highlights include:

  • Exploration programs have been successful in replacing mined depletion and
    adding to Mineral Resources and Reserves at all key mine operations. At
    Lundin Mining's 100% owned assets, contained copper and zinc in Measured
    and Indicated Mineral Resources, both increased by 4%.
  • At Tenke Fungurume, as per our previously filed (31 March 2011) Technical
    Report, Measured and Indicated Resources increased by 33% for copper and
    19% for cobalt above the prior year's estimates, for which Lundin Mining's
    attributable share through equity ownership is 24%.


Other items of note:

  • Copper Proven and Probable Mineral Reserves at Neves-Corvo have increased
    by 4.5 million tonnes (approximately 15,000 tonnes of contained copper).  
  • Zinc Proven and Probable Mineral Reserves at Neves-Corvo have been reduced
    from 42.6 million tonnes to 23.1 million tonnes reflecting:

- The zinc cutoff grade for reserve reporting being increased from 4.3% Zn to
5.0% Zn as a result of changed assumptions on by-product credits and operating
cost trends.

- Zinc Reserves from Lombador Phase II being re-categorized to Measured and
Indicated Resource status pending the completion of a strategic overall
property underground materials handling study currently underway and subsequent
economic assessments. 

  • Ongoing exploration drilling has again increased total copper and zinc
    contained in Lombador Resources. Development of a new exploration drilling
    horizon in connection with the advancement of the Phase I Lombador ramp
    will allow a program of underground exploration drilling to further define
    and potentially expand this important asset.   
  • The Semblana discovery has not been reflected in this Mineral Resource
    estimate.  Resource delineation drilling continues with four rigs and an
    inaugural resource estimate for Semblana remains on schedule for year end. 
  • The 3D seismic survey, completed in Q2, has successfully identified the
    extent of the Semblana deposit which will aid in the completion of the
    resource delineation drilling. In addition, 18 new exploration targets have
    also been identified in relatively close proximity to existing mine
    workings. All targets are interpreted to lie within the favourable mine
    stratigraphy, including satellite-type targets close to Semblana as well as
    targets located down-dip of the Zambujal, Corvo and Lombador orebodies.
    Drill-testing of the first of these targets has just commenced.
  • Mineral Reserves at Zinkgruvan have remained largely unchanged as the mine
    continues to consistently replace its production with new reserves.

The tables attached to this release summarize the Mineral Reserve and Resource
estimates for each of the Company's mines as of June 30, 2011. Mineral Reserves
and Resources for the Tenke Fungurume copper/cobalt mine, in which Lundin
Mining has a 24% equity interest, are reported as at December 31, 2010.

Forward Looking Statements

Certain of the statements made and information contained herein is
“forward-looking information” within the meaning of the Ontario Securities Act.
Forward-looking statements are subject to a variety of risks and uncertainties
which could cause actual events or results to differ from those reflected in
the forward-looking statements, including, without limitation, risks and
uncertainties relating to foreign currency fluctuations; risks inherent in
mining including environmental hazards, industrial accidents, unusual or
unexpected geological formations, ground control problems and flooding; risks
associated with the estimation of Mineral Resources and Reserves and the
geology, grade and continuity of mineral deposits; the possibility that future
exploration, development or mining results will not be consistent with the
Company's expectations; the potential for and effects of labour disputes or
other unanticipated difficulties with or shortages of labour or interruptions
in production; actual ore mined varying from estimates of grade, tonnage,
dilution and metallurgical and other characteristics; the inherent uncertainty
of production and cost estimates and the potential for unexpected costs and
expenses, commodity price fluctuations; uncertain political and economic
environments; changes in laws or policies, foreign taxation, delays or the
inability to obtain necessary governmental permits; and other risks and
uncertainties, including those described under Risk Factors Relating to the
Company's Business in the Company's Annual Information Form and in each
management discussion and analysis. Forward-looking information is in addition
based on various assumptions including, without limitation, the expectations
and beliefs of management, the assumed long term price of copper, nickel, lead
and zinc; that the Company can access financing, appropriate equipment and
sufficient labour and that the political environment where the Company operates
will continue to support the development and operation of mining projects.
Should one or more of these risks and uncertainties materialize, or should
underlying assumptions prove incorrect, actual results may vary materially from
those described in forward-looking statements. Accordingly, readers are advised
not to place undue reliance on forward-looking statements.

 

Cautionary Notes to Investors - Reserve and Resource Estimates

In accordance with applicable Canadian securities regulatory requirements, all
Mineral Reserve and Mineral resource estimates of the Company disclosed or
incorporated by reference in this news release have been prepared in accordance
with Canadian National Instrument 43-101 - Standards of Disclosure for Mineral
Projects (“NI 43-101”), classified in accordance with Canadian Institute of
Mining Metallurgy and Petroleum's “CIM Standards on Mineral Resources and
Reserves Definitions and Guidelines” (the “CIM Guidelines”). The definitions of
Mineral Reserves and Mineral resources are set out in our disclosure of our
Mineral Reserve and Mineral resource estimates in our Annual Information Form. 

 

The Company uses the terms “Mineral resources”, “measured Mineral resources”,
“indicated Mineral resources” and “inferred Mineral resources”. While those
terms are recognized by Canadian securities regulatory authorities, they are
not recognized by the United States Securities and Exchange Commission  the
“SEC”) and the SEC does not permit U.S. companies to disclose resources in
their filings with the SEC. Pursuant to the CIM Guidelines, Mineral resources
have a higher degree of uncertainty than Mineral Reserves as to their existence
as well as their economic and legal feasibility. Inferred Mineral resources,
when compared with measured or indicated Mineral resources, have the least
certainty as to their existence, and it cannot be assumed that all or any part
of an inferred Mineral resource will be upgraded to an indicated or measured
Mineral resource as a result of continued exploration. Pursuant to NI 43-101,
inferred Mineral resources may not form the basis of any economic analysis,
including any feasibility study. Accordingly, readers are cautioned not to
assume that all or any part of a Mineral resource exists, will ever be
converted into a Mineral Reserve, or is or will ever be economically or legally
mineable or recovered.
