VANCOUVER, Sept. 28, 2012 /CNW/ - SIERRA IRON ORE CORP (the "Company") is pleased to announce that it will begin the collection of a representative sample of 550 kilos of ore from the Veinte Zone located within the El Creston property. The sample will be comprised of 25 kilo samples that will be obtained with a spacing of about 10 meters between each sample hole. The samples will be sent to a major smelter in China for testing. The objective of the metallurgical testing is to determine the magnetite iron grade, by-product levels, and fine sizing. In addition, The Company will hire an independent 3^rd party inspection company to maintain the quality standards of the shipment and analysis of the samples.

The decision to quickly move to conducting a metallurgy test is based on the previous results announced on August 27^th, 2012 whereby the Company reported the first assay results from its core drill program. The results of the initial eight drill holes included six holes intersecting significant iron bands grading 30% iron ore or greater. The initial assay results of the six holes are highlighted by more than 66 meters of 30% iron or better including more than 33 meters of 45% iron or better.

"We are very pleased that the results announced on August 27^th, 2012 attracted many potential off-takers who contacted the Company", stated Wally Boguski, President and CEO. "The Company is independently proceeding with the metallurgy testing and we look forward to announcing the results after the samples have been fully processed."

Mr. Ruben Verzosa, P. Eng., a Qualified Person (QP) as defined by NI 43-101 has approved the geological content of this Press Release.
