Itronics to Sell GOLD'n GRO Guardian Deer Repellent in the West, Northeast, Midwest and South


RENO, NV--(Marketwire - May 5, 2008) - Itronics Inc. (OTCBB: ITRO) (FRANKFURT: ITG) (BERLIN: ITG) today reported that its wholly-owned subsidiary, Itronics Metallurgical, Inc., is in process of registering its one-of-a-kind GOLD'n GRO Guardian deer repellent and fertilizer for sales starting in June in:

Western U.S.:       Nevada, Utah, and Colorado.
Northeastern U.S.:  Connecticut, Delaware, Maryland, Massachusetts,
                    New Jersey, New York, Pennsylvania, and Rhode Island.
Midwest and South:  Iowa and Alabama

"GOLD'n GRO Guardian Deer Repellent can be sold in states in which it is being registered and, in each of these states, deer do major damage annually. We plan to add additional states after we establish sales in the targeted states," said Dr. John Whitney, Itronics President. "We have had numerous requests from potential customers about the products availability. Deer damage in suburban America is in the $5 billion range, according to an internal, detailed Itronics study, making the potential for this product enormous."

Itronics Metallurgical will sell the unique product to Landscape Maintenance businesses that have licensed pesticide spray divisions and to other business that are licensed for spraying pesticides. Sales will also be made to plant and tree nurseries in the listed states and to other customers. The product does not harm the deer and fertilizes at the same time.

GOLD'n GRO Guardian Deer Repellent is registered for use on non-food crops, landscape plants, and non-bearing trees and vines. Some soybean seed and corn seed growers have expressed interest in testing the GOLD'n GRO Guardian Deer Repellent on seedlings to protect them from foraging deer, which do major economic damage. Itronics Metallurgical plans to evaluate these potential applications for commercial viability as it moves forward because these would be large acreage uses. GOLD'n GRO Guardian is a systemic product and the treatment lasts up to 3 months.

Itronics Metallurgical is planning to sell the GOLD'n GRO Guardian as a two-part package consisting of the repelling component and GOLD'n GRO 8-8-8 +4%S liquid fertilizer. Initially three sizes of spray kit will be offered, a 4 gallon kit, a 12 gallon kit, and a 600 gallon kit, making it convenient for potential customers to do evaluation and testing, followed by conversion to commercial applications.
