Itronics Reports 2007 Financial Results: Increased Gross Profit; Fertilizer Sales Up 28 Percent; Sales Total $2.34 Million

RENO, NV--(Marketwire - April 16, 2008) - Itronics Inc. (OTCBB: ITRO) (FRANKFURT: ITG) (BERLIN: ITG) today reported a positive gross profit of $124,160 for 2007, up from $75,193 in 2006, an increase of 65 percent. Total sales increased by 25 percent to $2.34 million from $1.87 million for the full year.

The annual report for the year 2007 on Form 10KSB is available on the U.S. Securities & Exchange web site at http://www.sec.gov.

GOLD'n GRO liquid fertilizer sales were up 28 percent in 2007 compared to the prior year despite sales growth in the 2007 fourth quarter being flat due to water shortages and related fertilization curtailment in California's Central Valley. Sales growth resumed in the first quarter 2008 and is expected to continue for the entire year.

Silver sales in the fourth quarter of 2007 declined by 17 percent and total sales for 2007 decreased by 24 percent compared to the prior year primarily due to electrical power fluctuations outside the Company's control. Silver sales expanded in the first quarter 2008 and this expansion is expected to continue through the year. The silver price is at historical highs and is contributing to the 2008 sales increase.

Photo Service sales increased 162 percent for the full year 2007 due to three new spent photochemical supply contracts and the sale of a photochemical silver concentrator. In 2008 the Company expects to continue to expand used photochemical supplies and to sell another photochemical silver concentrator to produce an increase for the year.

Mining Technical Services were flat in 2007 while the division was making a transition from deriving its income from technical services to an Internet based revenue model through the newly launched Insidemetals.com internet information portal. In 2008 Mining Technical Services is continuing to advance its web based InsideMetals.com Gold Producer Stocks information portal: www.insidemetals.com, and it is obtaining and completing new technical services contracts. Both initiatives are significantly increasing revenues in 2008.

During the year the Company obtained $2.1 million in financing to fund operations and to continue its expansion. While additional funding will be necessary in 2008, the Company said it has begun efforts to seek alternative methods that have less impact on the stock price and number of shares outstanding.

Goals outlined for 2008 are to continue to expand GOLD'n GRO liquid fertilizer sales and silver sales; expand used photochemical raw material supplies by acquiring new photoservices contracts; implement the GOLD'n GRO Guardian liquid deer repellent fertilizer manufacturing and marketing; and continue to acquire financing to support growth. On-going sales growth is expected to produce a significant increase in Gross Profit in 2008.

The report reviews progress in implementing the Company's eight part long term growth plan. The Company's primary focus is on building the GOLD'n GRO brand by expanding fertilizer sales which are now the driver for overall sales growth in the fertilizer segment, and to begin manufacturing and selling GOLD'n GRO Guardian Deer Repellent. Silver refining is being expanded to accommodate increased volumes of silver produced by fertilizer sales expansion. InsideMetals.com is rapidly gaining recognition as a global internet brand and is now receiving visits from more than 170 countries world-wide.

Operating loss increased 32 percent compared to the prior year, primarily due to increased sales and marketing expenses. Net loss increased by 175 percent due primarily to increased loss on derivative instruments.
