Itronics Announces Discovery of Surface High Grade Zinc-Lead-Silver Mineralization at Its Auric Fulstone Copper Gold Project

RENO, NV--(Marketwired - Jan 20, 2015) - Itronics Inc. (OTC PINK: ITRO), a diversified liquid fertilizer and silver producer and developer of unique technologies in the mining and other industries, today announced that its subsidiary, Whitney & Whitney, Inc., has identified surface high grade zinc-lead-silver mineralization at its Auric Gold & Minerals Fulstone copper-gold exploration project in Nevada. The presence of zinc, lead, and silver is consistent with other major copper deposits that have been found and developed in the United States, Canada, and Mexico.

Discovery of the potential for significant zinc, lead, and silver mineralization at the Fulstone Iron Oxide Copper Gold project, which is located in the Yerington Mining District, increases the attractiveness of the project by adding potentially significant near surface zinc, lead, and silver values to the over-all copper and gold values that are anticipated to be found as the project is explored.

"Whitney & Whitney is studying some of the anomalous geochemistry and geophysics at the Fulstone Project," said Dr. John Whitney, Itronics President. "There is a large area that is anomalous for zinc which straddles a major fault and is over the top of one of our best geophysical anomalies. Samples were taken at two separate locations to determine if indications of potentially economic near surface zinc mineralization are present."

The sample locations were about 5,000 feet distance from each other within the zinc anomaly along the fault. The rocks at both locations are similar and have proven often to be favorable host rocks for zinc, lead, and silver at other mining districts.

One outcrop sample taken at the first location contained 27.0 percent zinc, 1.3 percent lead, and 1.2 ounces of silver per ton. Another grab sample taken from the same outcrop about 300 feet from the first sample contained 26.2 percent zinc, 2.1 percent lead, 0.6 ounces of silver per ton, 0.13 percent copper and a trace of gold. The samples also contain anomalous molybdenum. The unusually high zinc content of this set of samples was not expected based on an examination of the surface geology. Rock with this high zinc, lead, and silver content is an economic bonanza if enough tonnage can be identified by future detailed drilling.
