VANCOUVER, March 21, 2012 /PRNewswire/ --
Pan American Goldfields Ltd. (OTCQB: MXOM) (the "Company") is pleased to announce the mineral production and revenues received from its Cieneguita Project located in Chihuahua, Mexico for the third quarter ending November 30th, 2011.
The Cieneguita Project is currently being operated at a limited or pilot scale under an agreement with Minera Rio Tinto ("MRT"). Under this agreement MRT has the right to mine the first 15 meters depth of the deposit from which the Company receives 20% of net profits and 80% of any net profits from material mined deeper than 15 meters. After December 31st, 2012, 100% of the project reverts back to the Company and MRT has the right to earn a 20% interest by contributing on a pro-rata basis to the costs of the development of a planned larger operation. This larger operation is the subject of a preliminary economic assessment ("PEA") being prepared by M3 Engineering & Technology of Tucson, Arizona with an expected completion date of early third quarter 2012.
The Cieneguita Project hosts a NI43-101 compliant resource estimate above a 0.8 gram per tonne gold equivalent cut-off grade (using prices of $950/oz gold and $14.50/oz silver) of 20.1 million tonnes (measured + indicated) containing 474,900 ounces of gold and 33.5 million ounces of silver as defined in the company's technical report filed on SEDAR on October 22, 2010. It is estimated that no more than two percent of this resource will be mined under the current operating agreement with MRT.
At the MRT operation, mineralized material from a small open pit is crushed and ground in a ball mill of approximately 500-600 tonnes per day capacity, and then fed to a bank of flotation cells to produce a bulk sulfide concentrate. This concentrate is then shipped to an MRT owned facility in Choix, Sinaloa where it is reground and a saleable lead sulfide concentrate is produced which contains the valuable gold and silver. This lead concentrate is then sold to Trafigura who makes a provisional payment to MRT equaling 85% of the value of the concentrate with the balance paid within 10 days of the date of closing of the lot in Manzanillo. Based on the payments from Trafigura to MRT, MRT then subtracts the cost of mining, processing, royalties and general administration costs to calculate the net profits generated by the operation. The Company is then paid 20% of this amount.
Production at the Cieneguita site was negatively impacted by a drought which persisted through much of 2011, but the impact was lessened in the second half of the year through the construction of two water collection and storage facilities and improved water recycling efforts. These measures have helped to stabilize production at the rate of about 500 tonnes per day since July 2011. The Company is optimistic that this level of production can be maintained through the remainder of 2012.
Production in the Company's fiscal third quarter (September-November) averaged 496 tonnes per day through the ball mill, with average feed grades of 1.48 grams per tonne ("g/t") gold and 86 g/t silver, and recoveries of 89% and 90%, respectively. A total of 4,162 tonnes of bulk concentrate was produced during the quarter, containing a total of 1,843 ounces of gold and 109,486 ounces of silver. The Company has received payments for its share of net profits from third quarter production which total $399,281 for an average of $133,093 per month. All production through the third quarter is from the first 15 meters of the Cieneguita resource.
Production during the fourth quarter (December-February) averaged 466 tonnes per day through the ball mill, with average feed grades of 1.66 g/t gold and 81 g/t silver and recoveries of 89% and 90%, respectively. A total of 3,857 tonnes of bulk concentrate was produced during the quarter containing a total of 1,933 ounces of gold and 96,856 ounces of silver. Production during December 2011 was negatively impacted by repairs and maintenance to the ball mill and holiday closures. The Company is still waiting for the complete payments for its share of net profits from the fourth quarter of operation, but they should total at least the amount received for the third quarter.
The Company is currently in discussions with MRT regarding mining at depths greater than 15 meters which may result in a future increase in net profits attributable to the Company for all material processed in the current pilot operation.
