Itronics Updates Stage 1 Silver Refinery Expansion Progress

RENO, NV--(Marketwire - January 27, 2010) - Itronics Inc. (PINKSHEETS: ITRO) (FRANKFURT: ITG) (BERLIN: ITG) reported today that its subsidiary, Itronics Metallurgical, Inc., today provided a progress report on the Stage I silver refinery expansion announced in October 2009.

Itronics Metallurgical has completed the preliminary engineering, including specification of needed tanks and pumps. A tank list has been prepared and tank selection is underway. Evaluation of operating changes that will be needed to accommodate the new processing circuit is also underway. The current goal is to be able to start testing the new circuit in the second quarter.

"We are excited by the progress being made to advance this expansion project," said Itronics President Dr. John Whitney. "Once operational, this revolutionary technology will strengthen the company and open new pathways to growth."

In 2008, Itronics announced plans for expansion of its silver refining capacity in two stages from 24,000 ounces per year to 2.4 million ounces per year. The Stage I expansion will increase nominal silver refining capacity to 240,000 ounces per year by increasing the per melt capacity of the refining operation by 10 times with no increase in per melt cost. This produces a 90 percent decrease of the per melt cost of each ounce of silver produced.

The increase in per melt capacity will be more than sufficient to accommodate intermediate term growth, and will also provide the capacity for acquisition of new silver-bearing sources to further expand growth. The Stage 1 refinery expansion will produce two new fertilizer raw materials as byproducts which are expected to improve GOLD'n GRO fertilizer quality and profitability by replacing fertilizer ingredients which are presently purchased from outside suppliers.

Itronics, through its subsidiary Itronics Metallurgical, is the inventor and operator of award-winning recycling technology that converts spent photographic liquids into pure silver and GOLD'n GRO fertilizers. Commercialization of this technology has created a "Green Consumer Option" for photo and X-ray processors and "Green fertilizers" for horticulture and agriculture. The fertilizers incorporate the "essence" of green because of how they are sourced and because of their excellent performance in the field.
