Anvil Mining Produces First Copper Cathodes at Kinsevere Stage II Project

Common shares outstanding 157.3 million

MONTREAL, May 9 /CNW Telbec/ - Anvil Mining Limited (TSX, ASX: AVM) (the "Company"), is pleased to announce the first production of copper cathode at its flagship Kinsevere Stage II Solvent Extraction and Electro-winning ("SX-EW") mine located in the southern part of Katanga Province in the Democratic Republic of Congo ("DRC").

A total of 36 tonnes of copper cathode was harvested on May 4, 2011 and total copper cathode production to date amounts to 230 tonnes. The SX-EW section has been fed by copper solution from both heap-leaching and the first copper circuits.

In mid-April, irrigation of the heap-leach (on floats from the Stage I heavy media separation processing), which contains approximately 3% Acid Soluble Copper, commenced and resulted in the production of copper bearing pregnant liquor solution ("PLS") within two days. The off-flow PLS grade from the heap-leach circuit is exceeding expectations and currently ranges from 9 to 10 grams of copper per litre.

On April 24, the first Solvent Extraction ("SX") circuit commenced operation on the PLS produced from the heap-leach and within three days, sufficient copper units had been transferred to the Electro-winning ("EW") circuit to enable the rectifier to be energized. Copper plating commenced on April 27.

Separate from the processing of the heap-leach material, the crushing, grinding and leaching circuits commenced operation on April 27.  The circuit was run for an initial testing period of 17 hours after which a stoppage for routine testing was taken. The crushing and grinding circuits recommenced operation on April 28 with PLS production from an abridged copper circuit being achieved on the same day. Since early May the crushing and grinding operations have been running within a 75% to 85% range of design capacity and are expected to reach full design capacity in the near future.  The operating performance to date of the SX and EW circuits is pleasing.

Commissioning and ramp-up of the Stage II plant is an ongoing process that is expected to take several months to complete, however both the heap-leach circuit and the first SX circuit are performing well. The second SX circuit has now been handed over by the engineering, procurement and construction contractor, with commissioning expected to commence during May. While there are a number of construction and commissioning activities ongoing, the Company expects the commissioning to be substantially completed by the end of the second quarter and with the support of our commissioning management group, it is anticipated that design capacity will be achieved during the fourth quarter of 2011.

Darryll Castle, President and CEO of Anvil, commented: "The start-up of Kinsevere Stage II operations marks a significant milestone for Anvil. With the construction phase almost completed and commissioning progressing at a pleasing pace, the focus is firmly on the ramp-up to reach a production rate of 5,000 tonnes of copper cathode per month. I would like to extend my gratitude to our Congolese and expatriate employees, as well as our contractors and sub-contractors. I am especially proud of the remarkable safety record since the construction of the Kinsevere Stage II SX-EW plant commenced almost 18 months ago. With over 1,200 employees and contractors on site during the peak construction period, and over three million site man-hours expended, there have been only two lost-time injuries reported to date."

"It is also appropriate at this time to acknowledge the efforts and tenacity of Bill Turner.  He has worked relentlessly in the DRC for over 15 years in order to achieve the exploration successes which have resulted in the development and construction of three mines in the DRC, including our flagship Kinsevere copper mine.  Without the efforts, vision and dedication of Bill, this achievement would not have been possible."
