Itronics Will Report First Quarter Sales Increase; Updates Silver Refinery Expansion and GOLD'N GRO Guardian Deer Repellent Fertilizer Registration

RENO, NV--(Marketwire - March 6, 2008) - Itronics Inc. (OTCBB: ITRO) (FRANKFURT: ITG) (BERLIN: ITG) reported today that its first quarter sales are increasing in strong silver, fertilizer, and gold markets.

"Itronics GOLD'n GRO fertilizer division ended February with the largest backlog of truck load orders in the Company's history," said Dr. John Whitney, Itronics President. "Silver sales in January and February were about equal to last year's full first quarter. The Mining Technical Services division sales were also up in the first two months and visitor traffic to the InsideMetals.com web site is continuing to increase."

"The sales increases are expected to grow as the year progresses. Silver prices, fertilizer demand and prices, and gold prices are at all time highs," said Dr. Whitney. "Itronics, with its innovative photochemical recycling technology that completely converts the waste stream to pure silver and environmentally compatible, high quality GOLD'n GRO liquid fertilizers, is now benefiting from these strong markets."

The Company has completed temporary installation and start up of a new screening machine for its refinery that will produce an increase in silver output and sales in March and future months. Silver prices are now in the $20 per ounce range, making this incremental expansion very timely.

The Company has completed a detailed deer damage study which indicates that deer damage in suburban America is in the $5 billion per year range and that sales of its GOLD'n GRO deer repellent fertilizer could top $200 million annually. The U.S. Environmental Protection Agency has indicated that the Company will receive a GOLD'n GRO Guardian deer repellent registration sometime in May or June 2008. The Company is now anticipating that GOLD'n GRO Guardian deer repellent fertilizer sales can begin in the third quarter of this year.
