    Common shares outstanding: 70.4 million
    All amounts are expressed in US dollars, unless otherwise stated.

    MONTREAL, June 11 /CNW/ - Anvil Mining Limited (TSX, ASX: AVM) ("Anvil")
is pleased to announce that AMCK Mining sprl ("AMCK"), a Joint Venture company
involving Anvil (95%) and Mining Company of Katanga (5%) has commenced the
commissioning of the Heavy Media Separation ("HMS") Plant for the Stage I
development of the Kinsevere Mine, located 27km north of Lubumbashi, the
provincial capital of the Katanga Province in the Democratic Republic of Congo
("DRC").

    Commissioning of HMS Plant

    The commissioning of the HMS plant began during the first week of June
with the result that the first copper concentrates were produced on June 9,
2007. The plant, which is a standard configuration three-stage crushing and
screening circuit, scrubber and HMS plant is expected to be fully commissioned
before the end of June 2007. The design capacity of the HMS plant is 500,000
tonnes of ore throughput per year, or 1,370 tonnes per day. (Photos of the
plant and other aspects of the Kinsevere operations can be viewed by accessing
the following link:
www.anvilmining.com/documents/070611KinsevereStageICommissioningPhotos.pdf ).
Copper concentrates produced at the HMS plant will contain approximately 25%
copper and until the Electric-Arc Furnace ("EAF") has been completed, the
concentrate will be sold locally.

    EAF Construction

    The Stage I development of Kinsevere comprises an open pit mining
operation which commenced during the first quarter of 2007 on the Tshifufia
and Tshifufiamashi pits, the construction of an HMS plant and an EAF.
    Keech Furnace Technologies has completed the design of two 7.5 MVA EAFs
and civil works are progressing well. All steel for construction of the
building that will house the two EAFs has been fabricated and the shipment of
mechanical equipment and EAF components has commenced and is expected to be
completed within six to eight weeks. The commissioning of the EAF is planned
to take place during the fourth quarter of 2007. The plant is expected to
produce approximately 23,000 to 25,000 tonnes per annum of "black copper"
ingots assaying 90%-93%.

    Connection to DRC Hydro-electric Power Grid

    A Memorandum of Understanding was signed in December 2006 with Société
Nationale d'Electricité, the DRC government electricity company, for the
supply of 60MW (mega-watts) of hydro-electrical power to support both the
Stage I and the planned Stage II, 60,000 tonnes per year Solvent Extraction
Electro-winning ("SX-EW") developments.
    The Kinsevere Mine is being connected via a 120KV transmission line, to
the DRC national hydro-electric power grid in Lubumbashi. Clearing for the
27km direct line has been completed. Powerline Africa has been contracted for
the installation which is expected to be completed by the end of July.
    On site diesel powered generators will provide electrical power for the
HMS plant up until the time that the hydro-electrical connection is completed.

    Mining at Kinsevere

    Open pit mining on both the Tshifufia and Tshifufiamashi deposits
commenced in January reaching full capacity at the end of the first quarter.
The focus to date has been waste stripping at the Tshifufia pit where
approximately 1.9 million tonnes of waste stripping was required to expose
high-grade ore for early processing. Approximately 90% of this advance waste
stripping has now been completed.
    As of May 31, 2007, the Kinsevere stockpile of high-grade, medium-grade
and low-grade copper ores on the Run-of-Mine pad available for processing
through the HMS plant was as follows:

    -------------------------------------------------------------------------
    

    The progress made with the mining operations has placed the Company in a
position where it now has significant flexibility with respect to the blending
of ore to the HMS plant.

    Production Profile for Stage I

    The production profile of the Stage I HMS and EAF processing plant, up to
the commissioning of the SX-EW plant, is expected to be as follows:

    Kinsevere Mineral Resources

    In January 2007, the Company released the results of the Kinsevere
Phase 2 drilling program carried out during 2006. The 17,220 metre 2006
Phase 2 drilling program, which focused entirely on the Tshifufia deposit,
resulted in the preparation of an updated mineral resource estimate for the
Tshifufia, Tshifufiamashi and Kinsevere Hill deposits.
    The Kinsevere Mineral Resource estimates as at December 31, 2006 are
shown below:

Kinsevere Stage II In April 2007, following completion of a feasibility study, the Board of Directors approved the Kinsevere Stage II development at a capital cost of $238 million. The Stage II development, which involves construction of a 60,000 tonnes per year SX-EW plant, will produce LME Grade A quality copper cathode directly at the mine site. There are a number of important linkages between the Stage I and Stage II projects, with key aspects of the infrastructure developed for Stage I to be used during Stage II. For example, tailings from the Stage I HMS plant will be returned to the SX-EW plant for processing; the power line being constructed for the purpose of providing electrical power for Stage I will deliver sufficient power to support the Stage II 60,000 tonnes per year SX-EW plant and parts of the front end crusher for Stage I will be used to enable a higher level of throughput required for Stage II. Tenders have been called for the engineering, procurement, construction and management of the Stage II development and it is expected that an EPCM contractor will be appointed by the beginning of the third quarter of 2007.
