VANCOUVER, Dec. 4, 2013 /PRNewswire/ - FIRST MAJESTIC SILVER CORP. (AG: NYSE; FR: TSX) (the "Company" or "First Majestic") is pleased to announce that the Company's new 1,000 tonnes per day (tpd) cyanidation circuit at its Del Toro Silver Mine in Zacatecas, Mexico began initial production of silver doré bars on November 20, 2013.
"The commencement of silver doré production at Del Toro is another significant milestone for First Majestic this year," said First Majestic's President and CEO, Keith Neumeyer. "The Del Toro Silver Mine continues to be a substantial growth driver for the Company as silver production ramps up from this new mine. With the plant construction nearly complete, this achievement puts First Majestic on track to reaching its tenth consecutive year of growth in silver production."
Commissioning of the new 1,000 tpd cyanidation circuit began on October 20, 2013. Surface stockpiles consisting of lower grade oxide ore is initially being supplied to the mill for this ramp-up period. Mill throughput since initial commissioning has averaged 582 tpd with head grades averaging 168 grams per tonne silver. Initial silver recoveries in the oxide circuit have averaged 67%. It is expected that throughput, grades and recoveries will achieve commercial levels by December 31, 2013 and will come closer to rates indicated in the Pre-Feasibility Study (PFS) dated August 20, 2012. Six pours have now taken place with each pour resulting in better quality silver doré bars.The PFS released in August 2012 estimated a budget for the Del Toro project consisting of $76.6 million for the construction of the processing plant, $18.3 million for exploration and development, $12.2 million for mining equipment, $8.0 million for the shaft installation, and $9.1 million for indirect costs and contingencies. Following the release of the PFS and as of September 30, 2013, $68.4 million has been invested for the construction of the plant, $31.7 million for exploration and development, $10.4 million for mining equipment, $1.0 million on the pending shaft installation, and $3.8 million on indirect costs and contingencies. An additional investment of $52.6 million, including exploration, development, the original purchase price, facility ground breaking and foundation construction, had been made prior to the release of the PFS. Over the course of construction at the Del Toro project, there have been a number of improvements in design that have resulted in additional plant construction costs and additional underground mine development and exploration beyond what was outlined in the PFS. For example, the addition of tailing filters to create dry stack tailings has become company policy at each of its operations. Despite the higher upfront cost, these filters are anticipated to lower operating costs over the life of mine as approximately 80% of the water used in the milling process is recycled throughout the plant and results in a more favourable impact on the environment. In addition, the flotation tailings were originally planned to be pumped back into the mine, however, due to the need to reduce operating costs over the life of mine, an expansion of the current tailings facility was required to expand its capacity requiring higher upfront costs. Finally, the original 115kW power line construction design and cost estimate did not anticipate the power line having to take the route on which it is currently being constructed resulting in additional costs due to this rerouting.
