RENO, NV--(Marketwire - May 19, 2010) - Itronics Inc. (PINKSHEETS: ITRO) (FRANKFURT: ITG) (BERLIN: ITG) today updated 2010 sales progress, saying, "the Company is benefiting from strong market demand for fertilizer and silver, and growing worldwide demand for hard mineral and gold properties." Dr. John Whitney, Itronics President, said, "Silver prices have strengthened with silver now trading in the $19 per ounce range. With our Stage 1 silver refinery expansion under way and increased output expected in the second half of the year, Itronics silver sales will benefit from increased production, improved efficiency, and these strong prices.

With variable weather and continuing rains in our major central California market, the spring fertilizer season started later than usual. As a result, March GOLD'n 'GRO fertilizer sales were 40 percent greater than 2009, April sales were down slightly from April 2009, while May sales are expected to be up strongly. The weather continues to affect sales, with Reno, Nevada, still receiving late spring snow and California receiving more and later rain than usual. GOLD'n GRO fertilizer sales through the Company's distributor have been growing each year. Even with the unusual weather this year, the distributor sales base is expanding and forecasted growth is on track.

Work on the Stage 1 silver refinery expansion is on-going. The Company has been conducting small scale batch testing to develop additional information for actual operating requirements. This work has produced significant changes to the flow sheet that are expected to greatly simplify the operation and reduce the operational costs thereby significantly improving the project economics. Preparations for larger scale operational testing are continuing.

The claim staking project for Auric Gold & Minerals has been resumed. The Company has been receiving expressions of interest from potential investors which bodes well for the project as it develops. More information on the project will be provided at a later date.
