Toronto, January 23, 2012 (TSX: LUN; OMX: LUMI) Lundin Mining Corporation
(?Lundin? or the ?Company?) provides a summary of the results of the initial
Future Underground Materials Handling Study (the ?Study?) for its Neves-Corvo
mining complex in southern Portugal. This conceptual level study identified
and evaluated the underground materials handling and access options necessary
to pursue the exploitation of the deeper Lombador copper/zinc resources as
well as the Semblana copper deposit which are adjacent to the Company?s
Neves-Corvo mine.

The Study indicated two preferred options:

* A new rock-hoisting and man-riding shaft approximately 1,200 m deep,
located to the north-east of the existing mine surface facilities, situated
between the Semblana and Lombador mineralization (the ?Shaft Option?).
* A new decline from the existing plant area equipped with a conveyor system
and man and material access facilities (the ?Decline Option?). The Decline
Option consists of a proposed two-leg decline driven by a high speed tunnel
boring machine and would be aligned to pass close to and underneath the
Semblana deposit and then on to deeper parts of the Lombador resource,
reaching a similar ultimate depth as the Shaft Option.

The attached drawings illustrate the conceptual locations and layouts of these
two options.

The Shaft Option

The Shaft Option is expected to comprise conventional shaft systems with
combination skip/cages providing a designed rock hoisting capacity of 5
million tonnes per annum ("tpa"), coupled with rapid man-riding facilities to
the lowest levels of the mine. The shaft would provide direct ventilation
benefits and would allow ore and waste from production areas to be
gravity-fed to a new deep haulage level. The shaft is expected to provide
less positional and sequencing flexibility, as well as a longer development
schedule, as compared to the Decline Option. Should the Shaft Option be
selected, it could be in production approximately 5 years from project start.
The Shaft Option is expected to have a higher capital cost and lower
operating cost than the Decline Option.

The Decline Option

The Decline Option is expected to comprise an approximately 6-metre diameter,
inclined tunnel equipped with a conveyor system for rock hoisting, with the
same design capacity as the Shaft Option at 5 million tpa. At a current
design gradient of 1:5, the length of the decline from surface to the
Semblana area is approximately 5,200 m. Access to the deeper parts of the
Lombador mineralization would require a decline extension of a further 2,200
m. Man access would be provided by a rope haulage system or conventional
vehicles depending on the final selected gradient of the decline. The Decline
Option is expected to allow earlier first production than the Shaft Option,
with potential to be operational in approximately 4 years from project start.
This option would also allow phased expenditure and sequential development of
the Semblana and Lombador mineralization. The Decline Option could also have
the added benefit of providing greater flexibility in accessing several other
areas of potential mineralization located near the Semblana deposit as
identified by the recent high-grade copper intercepts from initial drilling
on 3D seismic targets, as announced in the Company?s December 15th, 2011
press release.

Study Advancement

A next level of study is advancing with a high priority, taking into account
ongoing new exploration results, and to further develop designs and
comparisons between the two options. The results of the initial Study are not
intended to imply that either option has been determined to be economically
viable. The Semblana mineral resource is still categorized as Inferred and
comments on economic potential are not provided. Given the preliminary nature
of the Study and the number of assumptions necessary to be made at this
stage, capital and operating cost estimates for the Shaft and Decline Options
are still at a conceptual stage and are insufficient for public
dissemination. Studies are advancing to refine comparisons between the Shaft
and Decline Options with anticipated completion by Q2 2012, to select a
single preferred option for subsequent feasibility level study.

A significant exploration drilling program is planned for 2012 which is
expected to increase the current resource at Semblana. Expansion of this
resource and drilling success from other nearby seismic reflector targets are
likely needed to warrant a major underground infrastructure investment
dedicated just to this area. Additional drilling is progressing near recently
encountered high grade copper intercepts south and southwest of the existing
Semblana resource.

Related Development Plans

In parallel to ongoing study work and to fast track the schedule for accessing
the Semblana area, the Company has commenced planning and budgeting for
development of an access ramp to the Semblana Deposit from the Zambujal
orebody. Subject to investment approvals, the ramp development is targeted to
commence prior to the end of Q2 2012 with the objective of accessing an
intermediate level about 750 m below surface in 2 to 3 years, from which
further exploration and infill drilling can be carried out. Subject to this
drilling, further design and study results, this ramp will continue to
approximately 950 m depth which is the conceptual design level of a main
haulage way for Semblana. This access ramp from Zambujal would be utilized
with either the Shaft or Decline Options.

As previously announced in our December 12th, 2011 press release, the
development of the Lombador deposit (?Lombador Phase 1?) is progressing to
enable ramp up of zinc production to in excess of 60,000 tpa by 2014. The
main access ramp for Lombador Phase 1 has now reached a level 850 metres
below surface and is at the elevation to start the exploration drive planned
for detailed in-fill drilling of the deeper Lombador mineralization.

Commenting on the Study and the Company?s other developments plans at the
Neves-Corvo mining complex, Mr. Paul Conibear, CEO of Lundin Mining said,
?The successive stages of refinement of the materials handling study are
essential for the future development of new resources at Neves-Corvo. We
intend to move forward aggressively with investment plans at the mine.
Ongoing exploration efforts on Semblana, Lombador, and the drilling success
we have recently achieved on new targets will continue to shape and support
our investment in future underground materials handling infrastructure at
