Equinox Publishes Preliminary Production Results for 1st Quarter 2011

TORONTO, April 25 /CNW/ - Equinox Minerals Limited (TSX and ASX symbol: "EQN") ("Equinox" or the "Company") announced today its preliminary production results for the quarter ended March 31, 2011 ("Q1-2011") from its 100% owned Lumwana Copper Mine ("Lumwana") in Zambia.

Ore mined for the quarter was 4.29 million tonnes, with 4.85 million tonnes of ore milled at a head grade of 0.66% copper and recoveries of 89.2% copper for production of 28,621 tonnes (63 M lbs).

Mined ore grade of 0.61% Cu was down on 4Q10 (0.69% Cu) as a result of the majority of ore being sourced from Stage 4 of the Malundwe Pit during the quarter. Grades for the remainder of the year are expected to increase as the percentage of Stage 3 ore mined increases with the average 2011 grade to be around 4Q10 levels.

Material movements of 19.4mt showed a significant increase (+29%) on the corresponding quarter for 2010, which is the relevant comparison due to the seasonal impact of the wet season on the operation. Key wet season management initiatives included the sheeting of haul roads in and out of the pit with basalt, increased pumping capacity and hot seat change overs.

Increased tyre wear during the quarter resulted in lower than expected fleet availability which hampered mining rates during the quarter. While tyre wear is expected to be higher during the wet season, it will reduce in the coming months. Productivity during the wetter conditions was also lower than usual and impacted the material movement.

Plant throughput for the quarter was 4.85mt which is within 3% of design capacity. Copper recoveries of 89.2% exceeded expectations and were in line with 4Q10 despite a drop in feed grade to 0.66% (4Q10: 0.69%).

C1 operating costs were $1.93 per pound which was an increase from Q410 ($1.64), due to the impact of lower head grades and resulting lower production and higher mining costs during the wet weather. Increased tyre wear and above budget diesel costs were the major reasons for increased unit mining costs during the quarter.

Sales for the quarter were impacted by operating issues at both the Chambishi Copper Smelter Limited operated by China Non-ferrous Metal Mining and Yunnan Copper (oxygen plant failure), and the Konkola Copper Mines Plc smelter at Nchanga on the Zambian Copperbelt (foaming incident).

Management reaffirms the production guidance for Lumwana for the 2011 year will be 145,000 tonnes of copper metal in concentrates at an average estimated C1 operating cost of $1.45 per pound. Equinox however notes that industry wide cost pressure such as diesel, consumables and expatriate labour present risks to cost guidance.
