GOLD’n GRO fertilizer sales in the first half were up 8 percent compared to 2012. Itronics is working with its distributor to continue to expand GOLD’n GRO sales by increasing the use of individual fertilizers within the established customer base, and by expanding geographically within our distributor’s exclusive territory.

Second quarter troy ounces of silver sold were up 62 percent but the realized price was down 18 percent resulting in a 33 percent revenue increase compared to the prior year second quarter. Troy ounces of silver sold in the first half were down 28 percent compared to the prior year first half, and the realized silver price was down 16 percent resulting in a 40 percent revenue decrease compared to the prior year first half. The Company believes that silver prices may stabilize and perhaps establish an uptrend in coming months, although they could continue to be volatile.

The volume of silver-bearing photographic liquids received by the Company from its established suppliers in the second quarter increased by 13 percent compared to the prior year second quarter and continue to be more than adequate to meet the requirements for anticipated GOLD’n GRO fertilizer sales increases.

The silver refined by Itronics is recovered from spent photo liquids, a highly acclaimed environmentally "Green" and beneficial process. The de-silvered photo liquids are converted to ingredients for use in manufacturing the Award Winning line of GOLD’n GRO liquid fertilizers. This technology maximizes sustainability by converting all of the silver-bearing photographic liquid waste into commercial goods for sale. There is no waste of any raw materials, including water, when this process is used. Itronics’ manufacturing plant which operates this technology is a fully permitted "zero discharge" facility.

Whitney & Whitney, Inc. technical services Revenue was up 155 percent in the second quarter and up 90 percent in the first half as a result of providing services for a long term client. Whitney & Whitney is receiving inquiries from potential new clients regarding provision of planning and development services for specific mine development projects. These inquiries may lead to new services contracts which would produce additional services revenues for the Company.
