:: Haber, Inc. Successfully Recovers Gold Using Environmentally Friendly Gold Process in Its U.S. Processing Facility

Haber, Inc, a Massachusetts-based company with proprietary technology for the environmentally friendly processing of electronic scrap (e-scrap) and precious metal bearing ores, announced today that it is has made a successful first run in its Massachusetts-based gold processing facility using Ghanaian ore and its environmentally friendly extraction and recovery system known as the Haber Gold Process (HGP).

The first bulk run consisted of 70 pounds of Ghanaian concentrate that was processed in a Haber mobile unit, designed to be used in remote areas. The process consisted of loading the mobile unit with the gold concentrate, adding HGP lixiviant, rotating the drum for a approximately three hours, then vertically articulating the drum and decanting by gravity. This was followed by pumping the pregnant gold solution into an open vessel. The tailing was then rinsed, decanted and pumped to the vessel. HGP recovery solution was then added and stirred for approximately two minutes, which immediately precipitated fine particles of gold metal. The solution was then passed through a filter where the gold metal was deposited on the filter pad. The gold produced by the HGP process weighed approximately one-quarter ounce. Its purity is currently being determined and assays are being performed on the concentrate, before and after processing, to determine the recovery efficiency. As the company announced previously, the facility's analytical laboratory is in the process of being completed. In the meantime, analytical testing will be done by outside laboratories, with results expected within several weeks. The company is confident that the test data will show the efficiency of recovery to be in the high 90 percent range, based on previous testing done in Ghana, where 99 percent efficiency was achieved on similar ore.

The mobile unit performed well and the operational information derived from the testing confirmed all of the chemical parameters established through previously conducted laboratory work.

"The positive results we acheived using concentrate from Ghanaian small-scale miners reinforces our confidence that Haber has the technology to implement the Strategic Abatement of Mercury and Poverty (STAMP) program we developed to eliminate the use of mercury by artisinal miners while alleviating the extreme poverty faced by these miners," said Albert B. Conti, president and COO of Haber. The company believes that STAMP can have a positive impact on the lives of millions of small-scale miners globally who, by using mercury to extract gold, make a subsistence living but pollute the environment and negatively affect their health and the health of their families. The company will continue to thoroughly test the Ghanaian ore until it exhausts the balance of the ore on hand (approximately 300 pounds). Various types of e-scrap will then be processed for gold using the Haber E-Scrap Process (HESP) system. The company presently has approximately 2,500 pounds of e-scrap in house and intends to perform initial bulk tests on a variety of e-scrap and ore types to maximize the data collected on all processes. Optimization of the process chemistry will follow when Haber's analytical laboratory is fully functional.

"This first run couldn't have been more successful," said Conti. "HGP performed beautifully on the Ghanaian concentrate. Although the gold initially produced in this facility will be modest, it's important for us to walk through the entire process a number of times and climb the learning curve in a deliberative way. We are anxious to go through initial runs with all the gold-bearing materials that we have in inventory, including ores and e-scrap, to uncover any problems that may exist with the various processes developed by the company."

Haber expects that larger capacity processing equipment will be arriving on site in late December, and after it is installed gold production will grow commensurately. This facility is a proving ground for all Haber's hydrometallurgical extraction and recovery technology. The goal is to develop scalable process equipment designs in this facility with the aim of starting a low risk, high-volume production facility within the United States. This current facility is not designed for high-volume production, but it will produce gold on every run it completes. Revenues from the sale of the accumulated gold will begin as soon as practicable. As the company previously announced, Albert Conti will be traveling to Ghana this month to continue discussions on the STAMP program.

It should be noted that there is no guarantee that Haber's projections and opinions will ultimately prove successful.
