Lustros Commences Production of Pregnant Leaching Solution at Its Copper Sulfate Plant in Chile

SAN DIEGO--(BUSINESS WIRE)-- LUSTROS, INC. (OTCQB:LSTS) announced today that its subsidiary Sulfatos Chile SA has completed all the processes necessary to generate Pregnant Leaching Solution (PLS), the final step before crystallization in the manufacturing of Food-Grade Copper Sulfate. The PLS accumulates in large pools where it will concentrate for a short period before it is pumped into the company's state-of-the-art crystallization plant and converted into 99% pure, Food-Grade Copper Sulfate Pentahydrate.

The process starts with mineral extracted from the company's Anica copper mine. This mineral is then crushed to 0.25 inch pellets at its crushing facility and transported to the leaching pads, where it is irrigated with a mixture of sulfuric acid and water to create a solution with a heavy concentration of copper. The plant utilizes solvent by extraction technology to separate the copper from the liquid solution before it is purified and crystallized to very strict specifications.

Bill Farley, CEO and Chairman of Lustros, Inc., commented, "I am pleased that progress is continuing and that we've reached this important milestone. We will first be in pilot production and then look forward to a sales program in the near future."

"This is a moment of celebration for our employees and all other people involved in the project. After 30 months and over $10 million invested, our world class facility in Chile is beginning to show tangible rewards for our efforts," said Gonzalo Troncoso, President of Lustros, Inc. and CEO of Lustros Chile SpA.

Major Accomplishments:

  • The plant required 50 hectares and the team acquired 830 hectares for future expansion.
  • Water requirements are 2 liters / second and the site is permitted for 18 liters / second.
  • Original processing capacity was 5,000 tons / month and has increased to 15,000 tons / month.
  • Original copper mining rights were for 25 hectares and have increased to 1,325 hectares.
  • Electrical capacity required is 1.5 Megawatts and actual electricity available is 3.5 megawatts.
  • Crystallization plant capacity has increased from 3 grams per liter to 7 grams per liter.
  • End product production target has increased from 3,000 tons per year to 4,200 tons per year.
  • Chilean Government's Secretary of Mining in Coquimbo provided written endorsement of the quality, standards and professionalism of the plant construction in the Canela region.

About Copper Sulfate

High grade copper reserves are decreasing worldwide. This reality prompted Lustros to develop copper sulfate (CuSO4), a value-added product directly derived from copper. One kilogram of copper yields approximately four kilograms of Copper Sulfate.

Copper sulfate has various rich fundamental properties that make it a useful commercial chemical. It is widely used as a fungicide, herbicide and pesticide as well as an analytical reagent. Demand is increasing rapidly for use as a healthy additive to animal feed to induce hunger naturally.

Approximately 50% of copper sulfate produced globally is made from copper scrap that contains toxins (such as Dioxin), which are no longer accepted by Canada and other important consumer countries. Lustros' copper sulfate is produced directly from mineral content and is free from scrap pollutants making it an ideal Feed-Grade Copper Sulfate used for agricultural purposes.

There is strong interest from companies in Brazil, Canada, Colombia, Peru, and Chile to purchase Feed-Grade Copper Sulfate in quantities exceeding Lustros' potential production capacity.
