VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 30, 2015) -

(In United States dollars, except where noted otherwise)

First Quantum Minerals Ltd. ("First Quantum" or the "Company") (TSX:FM)(LSE:FQM) today announced a comparative loss1 of $12 million or $0.02 per share and cash flows from operations, before changes in working capital and tax paid of $131 million for the three months ended March 31, 2015.

HIGHLIGHTS

• Kansanshi smelter's technical commissioning successfully completed. Ramp-up progressing well with subsequent reduction in the mine's copper concentrate inventory and use of by-product sulphuric acid in the mine's oxide and mixed ore circuits replacing third-party purchases.
• Sentinel Train 1 progressing towards steady-state operations. Ramp-up during the peak of the wet season achieved periods above nameplate design throughput. Commissioning of Train 2 continued. Commercial production for the mine currently expected in Q3 2015.
• Production and unit cash cost of main metals for Q1 in line with full year 2015 guidance which takes account of:
  • The successful ramp-up of the Kansanshi smelter to date.
  • The easing of constraints on concentrate production at Kansanshi as the increasing smelter capacity allows the concentrate inventory to be further reduced.
  • The diminishing reliance on costly, third-party and manufactured sulphuric acid as the smelter ramps-up allowing more efficient and lower cost processing of oxide and mixed ores at Kansanshi.
  • Increasing gold production at Kansanshi in line with recovering copper production.
  • The closure of Ravensthorpe for the first 32 days of 2015 and the operation of only the high-pressure acid leach circuit thereafter until the repair and reintroduction of the atmospheric leach circuit into operations.
• Q1 production and cash cost:
  • Copper - 96,318 tonnes at $1.39 per pound; Nickel - 6,268 tonnes at $4.40 per pound; Gold - 52,782 ounces
• Realized copper price 17% lower while realized nickel and gold prices relatively unchanged compared to Q1 2014.
• Q1 2015 EBITDA of $33 million includes $62 million non-cash impairment charge on Guelb Moghrein's magnetite plant, $48 million of higher royalties in Zambia and $9 million in net foreign exchange losses.
• Comparative EBITDA 1 of $120 million for the quarter excluding impairment charges, restructuring costs and foreign exchange losses.
• Received agreement for and finalized requested changes to the Net Debt to EBITDA covenant. With this, the Company remains compliant with all finance covenants under the Financing Agreements and expects to remain so in the future.
• On April 20, 2015, the Zambian government announced proposals to revise the 2015 taxation regime in the mining sector. The proposed changes would decrease mineral royalties to 9% for open pit and underground mines and reinstate corporate tax to 30% with variable profits tax of up to 15%. Implementation is expected from July 1, 2015 and therefore the proposed changes have no impact on the results for Q1.
• Construction of the Cobre Panama project continued to make good progress. Overall detailed design is approximately 65% complete, engineering of major areas is well in advance of site requirements and site earthworks well progressed.

CEO'S COMMENTS

"We're very pleased with the rapid ramp-up of the smelter which reflects the diligent work done throughout the planning and construction of the project to ensure this outcome. As a result, Kansanshi's concentrate inventory is being reduced and sulphuric acid from the smelter is being used in the mine's processing facilities in higher volumes and much earlier than anticipated in our operating plan," noted Philip Pascall, First Quantum's Chairman and CEO.

"Likewise, the ramp-up of the Sentinel mine is steadily improving as the wet season in the region eases. Over the remainder of the year, we expect the Company's total production and unit cost to reflect the benefits of having a dedicated smelter, Sentinel's increasing production and the opportunity at Kansanshi to treat more mixed and oxide ores with free acid from the smelter.

"Kansanshi's Q1 performance was in line with previously-provided guidance for 2015. In that guidance, we mentioned that the mine's output was expected to be at its lowest for the year during Q1 because we intended to limit sulphuric acid consumption, and hence production, until free acid became available as a by-product from our smelter. The latter is now being realized. The good operating performance of our other mines is also notable. Besides Kansanshi and Ravensthorpe, which is recovering from the failure in one of its atmospheric leach tanks, all our other operations were cash positive and profitable for the quarter.

"At Cobre Panama, development of all aspects of the project is progressing as planned. The project is running well and we will continue to seek every opportunity to improve it further.

"With the uncertainty on prices for our main metals, we continue our efforts for the Company to withstand a period of prolonged lower metal prices while maintaining our ability to build future production. Sadly, among other initiatives, we have reduced our workforce in many areas of our Company. Such decisions, though not uncommon in our industry, are not easy ones. I wish to thank these past employees, as well as those continuing with us, for their service and contribution to First Quantum over the years," Mr. Pascall concluded.
