                                                               TSX, ASX: AVM
                                     Common shares outstanding 150.4 million
    All amounts are expressed in US dollars, unless otherwise stated.

MONTREAL, Jan. 27 /CNW Telbec/ - Anvil Mining Limited (TSX, ASX: AVM), ("Anvil" or the "Company") AMCK Mining SPRL ("AMCK"), a Joint Venture company formed by Anvil (95%) and Mining Company of Katanga SPRL (5%) today reported an updated analysis of its Stage II 60,000 tonnes per year Solvent Extraction and Electrowinning ("SX-EW") development at its Kinsevere Copper Project, located approximately 30 km north of Lubumbashi, the provincial capital of the Katanga Province in the Democratic Republic of Congo ("DRC"). The updated economic analysis follows completion of a new Mineral Reserve estimate, revised mine plan and completion of a Lump Sum Turnkey ("LSTK") contract with Ausenco Limited ("Ausenco").

AMCK has an exclusive "Contrat d'Amodiation" (Lease Agreement) with La Générale des Carrières et des Mines ("Gécamines"), the title holder of the mineral rights. In January 2009, the Company reached agreement with Gécamines and the Government of the DRC on the terms of the Lease Agreement.

Key outcomes of the updated economic analysis of Kinsevere Stage II:

    - A Net Present Value ("NPV"), at 95% equity of $683 million after tax;

    - Internal Rate of Return of 79%;

    - A payback period of less than 2.5 years after final loan drawdown;

    - Cash cost of $0.89/lb Cu (C1);

    - Total operating cost of $1.33/lb Cu (C3);

    - Commercial production expected to be achieved during the second quarter
      of 2011;

    - Proven and Probable Mineral Reserve of 20.8 million tonnes at an
      average grade of 3.9% total copper ("TCu") available for Stage I and
      Stage II processing;

    - Contained acid soluble copper of approximately 690,000 tonnes;

    - Peak mill throughput of 1.6 million tonnes per annum; and

    - Operational life of 14 years.

Bill Turner, President and CEO of the Company said: "Kinsevere Stage II is the Company's flagship project, with outstanding economic returns, reflecting the exceptional quality of these copper deposits located in the renowned Katangan Copperbelt. It is pleasing to see the construction works at Kinsevere starting to gather pace and we look forward to completing this project and commencing commissioning in early 2011. During the last two years, a significant amount of work has been undertaken to further enhance our understanding of the Kinsevere ore bodies and we are pleased to have completed an updated Mineral Reserve estimate. The sulphide portion of the Kinsevere orebodies beneath the defined oxide reserves remains open at depth and as optimization studies continue and with further drilling, there is scope to increase the sulphide resources".

Applying a discount rate of 10%, the economic analysis has been based on a Stage II project construction capital cost of $400 million, commissioning commencing in the first quarter of 2011, a six-month ramp-up period to full production, a Mineral Reserve estimate of 20.8 million tonnes with an average grade of 3.3% acid soluble copper ("ASCu"), an average head grade of 4.0% ASCu over an initial eight year period followed by a period of reclamation from lower grade stockpiles, an open pit waste to ore ratio of around 1.2:1, an average copper price of $2.44/lb, corporate tax in the DRC of 30%, and royalty payments of 2.5% of gross revenues to Gécamines and 2% Net Smelter Return ("NSR") to the DRC Government.

The outcomes associated with the economic analysis are highly sensitive to variations in copper price, with every 10% change in the copper price resulting in a change of $120 million in the NPV. Movements in other key variables have a less significant impact. For example, a 10% change to capital expenditure results in only a 2% change in the discounted cash flow, whilst a 10% change in the operating costs results in a 7% change in the discounted cash flow.

Capital Cost Estimate

The capital cost estimate for construction of Kinsevere Stage II of $400 million includes $200 million already spent. The LSTK contract with Ausenco was signed on January 22, 2010 for a total value of $130 million. Owner's Costs, which include purchase and transportation of the remaining capital equipment, spares, first fills, initial training and pre-commissioning costs and associated taxes and duties amount to $58 million, which together with contingency of $12 million, brings the total remaining cost to $200 million.

At December 31, 2009 the Company had unaudited cash reserves of $121 million, available-for-sale securitised investments of $18 million and receivables of $18 million. The Company is well advanced in discussions with a syndicate of banks to refinance the $100 million loan facility established with Trafigura Beheer B.V. ("Trafigura") in December 2009, to an amount of $140 million. The additional funding is sought in order to ensure that the Company has sufficient funding available to meet the Stage II ramp-up costs that are expected to be incurred during the first half of 2011, the pas de porte payment due to Gécamines for the Company's Mutoshi project and the recommencement of exploration and development activity.

Kinsevere Stage II Operating Parameters

The revised life of mine plan has a Stage II mining life of approximately eight years, during which time approximately 18 million tonnes of ore will be mined to produce a total of approximately 631,500 tonnes of contained copper metal. Processing of material from long-term stockpiles is expected to continue for another six years following the completion of mining of the current reserves. The peak ore processing rate is 1.6 million tonnes per year. A summary of the key operating parameters for Stage II is shown in Table 1.

Progress with Kinsevere Stage II

Following the receipt in September 2009 of the Tranche 1 funds of $32 million relating to the $200 million financing agreed with Trafigura, an Early Works Program was initiated on the Kinsevere Stage II project, with progress being made in a number of areas since this date, including:

    - Steel erection - 213 tonnes of pre-fabricated pipe rack steel have been
      erected, representing approximately 9% of the total requirement.

    - Contracts - security, catering and earthworks contracts negotiated by
      Ausenco are in an advanced stage of documentation and are expected to
      be finalised shortly.

    - Critical path issues - steel for the sulphuric acid tanks has been
      ordered and fabrication of a variety of other tanks is near completion.

    - Stockpiles of cement, sand and aggregate - orders and initial payments
      for the total stock requirement of cement and additives for the
      remainder of the project have been made and the first two of four
      deliveries of cement were received in November 2009.

    - New orders - purchase orders have been prioritised according to
      schedule requirements and are being prepared and committed.

    - Transportation of goods in storage - equipment items held in storage
      since Kinsevere Stage II was placed on hold have been reviewed and
      categorised according to priority. Delivery of these goods to site is
      underway and the Company expects to take delivery of the majority of
      this equipment before March 31, 2010.

    - Work permit applications - Ausenco has assumed full responsibility for
      obtaining work permits and the process is underway for identified

    - Camp refurbishment - significant progress has been made in relation to
      the junior and senior accommodation, laundry and messes.

Group Five Projects ("Group Five") is being engaged by Ausenco to undertake the Kinsevere Stage II construction and fabrication works. Prior to November 2008 when the development of Stage II was placed on hold, Group Five was contracted to perform this role and as a result has a sound understanding of the Stage II development. In addition Group Five has an established presence in the DRC and is well equipped to manage logistical, regulatory and other issues associated with operating in the DRC.

Group Five and Ausenco have already begun mobilising to site and it is expected that by February 2010, more than 100 Group Five personnel and 15 Ausenco personnel will be on site.

The engineering and design works which recommenced during the third quarter of 2009 are approximately 95% complete, with 2,057 drawings of the total of 2,160 now completed. In addition, a substantial amount of vendor data has been received.

With the commencement of the Early Works Program, the engagement of Group Five, the near completion of the engineering and design works and the mobilisation already underway, the Company is well positioned to allow for a timely recommencement of full-scale construction and fabrication works at Kinsevere Stage II.

Proven and Probable Reserve Estimate at Year-end 2009

The Proven and Probable Mineral Reserve estimate at year-end 2009 shown in Table 3 totals 20.8 million tonnes at an average copper grade of 3.3% ASCu, representing approximately 690,000 tonnes of contained acid soluble copper. The copper price used for the Mineral Reserve estimate was $1.43/lb Cu flat and the cut-off grade was determined as 0.7% ASCu. The Mineral Reserve estimate was derived from conventional mine planning processes including Whittle optimisation, detailed pit designs and life of mine production scheduling. The total Mineral Reserve includes additional previously mined ore located on various long-term stockpiles, available for either Heavy Media Separation ("HMS") or SX-EW processing, as shown in Table 3.

The Mineral Reserve has declined from 2008, as a result of ore extraction to feed the Kinsevere HMS plant, together with mineral resource model density and grade estimation differences.

Measured and Indicated Resource Estimate at Year-end 2009

The Measured and Indicated Mineral Resource for oxidised mineralisation at year-end 2009 (Table 4), using a 0.7% TCu cut-off grade is estimated at 25.7 million tonnes at an average grade of 3.1% ASCu, representing approximately 807,000 tonnes of contained acid soluble copper. The Proven and Probable Mineral Reserves included within the Measured and Indicated Mineral Resource are for oxidised mineralisation. The oxide and sulphide Inferred Mineral Resource is estimated at 14.2 million tonnes at an average grade of 3.6% TCu for approximately 507,000 tonnes of additional contained total copper.
