Itronics January-May 2013 Total GOLD'n GRO Fertilizer Sales up 17 Percent

  Itronics Inc. (PINKSHEETS: ITRO) reported today its January through May 2013 GOLD'n GRO fertilizer sales are up 17 percent compared to the same time period in the previous year. The fertilizer sales improvement continues the trend of the sales expansion reported for the fourth quarter of 2012.

The sales increase is primarily due to increased use in the California market by customers of our major distributor. The Company expects that sales will continue at higher levels.

GOLD'n GRO fertilizers, which have won worldwide awards for their environmental benefits, provide improved nutrient uptake by the crops so that smaller quantities can be used as compared to competing fertilizers. Over the years field testing has also demonstrated meaningful crop yield improvement. Recent Itronics press releases have provided specific examples.

"Improvements in yield and in environmental compatibility are very attractive to our distributor and its customers," said Dr. John Whitney, Itronics President. "GOLD'n GRO is a truly 'Green' line of fertilizers due to the innovative recycling technology used in manufacturing."

Information about GOLD'n GRO fertilizers is available on its website at www.goldngro.com or by calling 1-800-368-1865.

Itronics' technologies maximize sustainability. The Company is using science and engineering to pursue profitable clean technology driven growth in chelated specialty fertilizers, silver, and related technologies and products. "Itronics as a fertilizer and silver producer, and a large-scale iron copper gold mineral exploration property owner, is well positioned for its future," Dr. Whitney said.
