Largo Resources provides operational update
Symbol: LGO (TSX.V)
TORONTO, Aug. 21, 2013 /CNW/ - Largo Resources Ltd. ("Largo" or the "Company") provides an operational update for its Maracás Vanadium Project in Bahia, Brazil.
While Largo is pleased to inform investors that the majority of the system areas at the Maracás Project remain on track for commissioning in the Fourth Quarter of 2013, the Company hereby announces that a delay to the erection of the kiln has occurred because of the need to recast four of the support rollers required for the kiln. Delayed delivery of the rollers has forced Largo to revise its final schedule for the mechanical completion of the kiln area, and therefore for full commissioning of the Maracás Vanadium Project by approximately one month, to February 2014 (The additional delay will include a 10 day holiday by contractors over the Christmas period).
As announced on June 13, 2013, recasting became necessary when the quality standards of the original rollers procured from the kiln manufacturer were not met by its subcontractor. The four replacement rollers in question were only available to be loaded onto a ship at port on August 15, 2013 and are currently en route to Brazil. They are expected to arrive at site by early October, 2013.
At this time, Largo does not foresee, nor has any reason to believe, that there are any other issues that would cause additional delay beyond the current revised commissioning date.

Comments from Mark Brennan, President and Chief Executive Officer for Largo:
Mark Brennan, President and Chief Executive Officer, stated, "The Largo technical team have done a great job to keep the project on schedule to date and are disappointed that we have seen a delay of commissioning at Maracás due to a single delivery delay arising from subcontractor problems achieving required quality levels. Largo has explored all options to further expedite the completion of the kiln area to maintain the originally targeted year end commissioning date, but given the revised delivery schedule of the rollers, this will not be possible."
He continued, "All other system areas at Maracás remain on track and are expected to be commissioned before, or during, the Fourth Quarter of 2013. Each system area will have been dry and wet tested and will therefore be ready for operations upon the completion of the kiln. As the rollers are now on a ship to Brazil, we are very confident that our revised February target date will be met."
Comments from Mauro Pereira, Project Director, for Promon Engineering - EPCM Contractors:
Mauro Pereira, of Promon Engineering, on behalf of the Promon Project team stated: "We consider significant progress has been achieved at the Maracás project to date. Construction of all areas and systems of the plant, apart from the kiln, remain on schedule for expected commissioning before the end of the year. We at Promon are extremely satisfied with the advancement of the project to date."
Mr. Pereira further stated: "The management of complex projects aims at mitigating risks, including those relating to supplier and sub-supplier deliverables, diligent oversight and expediting all concerned participants is part of management activities. Nevertheless, problems do occur as shown in the case of the kiln rollers. Both Largo and Promon management teams have worked to minimize the impact of that setback and re-schedule the kiln's erection according to the best possible timetable given the new arrival times of these rollers. We are also confident in this plan and expect the revised date of February, 2014 to be achieved."

Overview of Site Development:
Significant progress has been made in all areas at the project site. Civil construction, which involves the pouring of foundations and structures for equipment, is now ramping down and will be complete by mid-September. Good progress is being made as well on the electrical-mechanical assembly front. The majority of the steel structures for equipment and mechanical connections is now in place together with associated equipment.
Major equipment has been arriving at site on an almost daily basis. Some recent arrivals include: the deammoniator, all four belt filters, the boiler and all the live rings for the cooler and kiln. Several pieces of major equipment, including both ball mills and four belt filters, have been placed on their final bases. Fabrication of all remaining equipment procured from off-shore has concluded with shipments either anticipated in the near-term or already underway.
Overview of Kiln Erection Schedule:
The kiln package is the largest piece of equipment at the project and consists of a 90-meter long kiln which will rest on three piers and a 32-meter long cooler that will rest on two piers.
The erection process has already commenced with the placement of the base plates over the concrete piers. Following this, the bearings stands and support rollers will need to be installed. These will then be aligned before the shells are put in place and the shells' rings mechanically coupled. Following this, the whole body of the kiln will be lifted into place and aligned on the rollers for welding. This will be followed by the drive installation and refractory application which is the last step in the erection schedule.
The ancillary equipment (cooler, electrostatic precipitator, fans, burners, stack and off-gas ducts, conveyors, silos and miscellaneous) will be erected in parallel along with the Kiln.
Comments from Les Ford, Technical Director of Operations for Largo:
Les Ford, Technical Director of Operations, stated: "The kiln system is certainly the largest piece of equipment at the project, and one of the most critical in the processing of vanadium. Likewise, the schedule for its erection is the longest and most intensive. Despite this, once heated and operational, ramp-up to production of first V2O5 product is usually relatively quick and straightforward."
He continued: "Following the completion of mechanical erection for the kiln (outlined in Figure 1 below), it will be fired and heated for approximately 1 week. After this, we will begin feeding concentrate through the kiln. We expect it will take approximately 5 days to fill the plant with material, after which point, we will have our first salable V2O5 product. I have been involved in the erection and operation of several kilns during my 40 year career in the vanadium industry and I am confident that we can ramp-up efficiently."
He further stated: "The kiln operation at Maracás will benefit hugely from the high V2O5 content and very low SiO2 content in the concentrate feed. V2O5 is almost double the grade and SiO2 is half in the Maracás kiln feed compared with the best of the South African operations. High SiO2 requires an increased amount of sodium in the kiln feed to give an acceptable vanadium solubility. The increased sodium with the SiO2 results in potential buildup in the kiln, and production of fused material, which causes downtime on the kiln and lower recoveries. Maracás is extremely fortunate that the quality of the concentrate is so good that it gives the potential to achieve higher kiln availability, and higher vanadium solubility than any other operation."
