1. Silver and Fertilizer from Photo Wastes John W. Whitney Founder, Chairman, President, Itronics, Inc. (OTCBB: ITRO; Frankfurt and Berlin:ITG) Eliminating Waste and Improving Crop Productivity by Converting Used Photographic Chemicals to Pure Silver and High Quality GOLD’n GRO liquid Fertilizers August 5, 2006 Presented at the Southern California Small Cap Investor Conference Orange County Airport Hilton

2. Itronics - Participating in the Digital Technology Revolution Image capture technology is changed –Digital capture now partially replaces film capture Kodak is no longer the dominant U.S. camera company Hewlett Packard, Sony, Motorola, Nokia, Cannon, Google, Yahoo, Shutterfly, and others have entered the industry Image print technology is changing –Inkjet printing is being marketed to replace silver halide prints Consumers are taking more pictures and buying more prints using both conventional and digital cameras Silver halide photo prints are cheaper, better quality, and more permanent than inkject photoprints; consumers continue buy price and quality

3. Itronics - Converts Photowaste to Pure Silver and GOLD’n GRO fertilizers Operates photochemical recycling and GOLD’n GRO liquid fertilizer manufacturing facility in Reno, Nevada In early stages of long term expansion guided by an eight part 5 year growth plan that is updated annually In 2005 completed 15 years of R & D with a cumulative expenditure of $24 million

4. The Markets -- Photowaste Services, Silver, and Fertilizer The U.S. Environmental Protection Agency says silver bearing photoliquids are a 100 million gallon toxic waste stream in the U.S. Management of silver bearing toxic waste streams required under U.S. EPA RCRA because silver in water is toxic to fish Regulatory authorities are encouraging development of recycling technologies that increase the amount of materials used beneficially

5. Photosilver Disposal in the US 55 million ounces used in photography in US Silver is the toxin that must be removed from photowaste; methods include: – Partial de-silvering on site followed by discharge to sewer –Capture at the source, de-silvering off site, transport to sanitary or hazardous waste land fill –Capture at the source, de-silvering and concentration off site followed by incineration Itronics has pioneered Silver Thiosulfate recycling, a new option for completely eliminating photowaste

6. Photowaste in the US Photo waste is generated by medical, dental, veterinary, and consumer photo processing Well known companies such as Walmart and Costco and many drug and grocery store chains offer digital and conventional photo print production Hauling and disposal services are provided by national Companies such as Safety-Kleen and Philip Environmental Services and by smaller regional companies

7. The Markets --Photowaste Services Silver and Fertilizer Using Itronics’ technology, 100 million gallons of waste photoliquids are sufficient to manufacture 200 million gallons of GOLD’n GRO fertilizers, or 1 million tons 100 million gallons of photowaste contains about 20 million ounces of silver; today worth about $220 million The combined market for Itronics services and products is approximately $1 billion in the U.S. The total fertilizer market in the U.S. is 50 million tons, a market of approximately $16 billion Itronics is targeting a 35% gross profit margin

8. Itronics’ Recycling Technology Advantages Removes 100% of silver and converts residuals to usable products: –Zero discharge facility – consumes all input photowastes Environmentally compatible GOLD’n GRO fertilizer manufactured from liquid portion Silver extracted from solid portion Solid residual can be converted to non-toxic tile products

9. Itronics’ GOLD’n GRO Fertilizer Advantages GOLD’n GRO is 1.5 to 3 times more effective than other products –More economical for farmer because less fertilizer is needed Crop production is increased by up to 40% Reduces surface run-off and ground water contamination due to reduced fertilizer requirement 90% reduction in the amount of zinc metal needed-soil residuals and accumulation eliminated

10. Itronics - Award Winning Creative Environmental Technology 2000--John Whitney was selected as Nevada’s Inventor of the Year. 2001--One of five finalists for the 2001 Kirkpatrick Chemical Engineering Award 2005--Awarded second place (IChemE), Worldwide Environmental Awards in London, England 2005--Awarded USA Gold at the International Green Apple Environmental Awards in London, England 2005--GOLD'n GRO® was named one of the top 10 new technologies representing the best of agricultural innovation by the Canadian Association of Agri-Retailers 2006- Itronics named International Green Hero by the Green Organization, London, England
