Introduction
Most
technological improvements can be easily recognized. We come in contact
with new technology on a daily basis whether its e-commerce, cellular text
messaging, or conducting business from your seat on a plane. Technology
effectively enriches our lives while enabling society and all forms of industry
to be more productive. Even the mining industry has felt the benefits from
new technology with the enhanced ability to locate and mine gold ore. Although
the average annual price of an ounce of gold has dropped by over $100 during
the past three years, gold producers still need to satisfy their shareholders
with a respectable bottom line. Worldwide demand for gold is running about
30% ahead of supply according to the World Gold Council. This fact further
requires gold producers to do just that... Produce. With gold prices at
a 20-year low, there is greater emphasis being placed on employing the most
effective and economical method of processing gold ore. This is where the
break-through technology from Orex Gold Mines Corp. for providing a low
cost and environmentally safe method of processing gold ore comes into play.
Gold Mining Technology
Much
of the gold mined today consists of fine particles of gold disseminated
in small concentration within the ore. The ore is crushed or ground to a
fine powder and the gold is extracted from the ore by dissolving it. Gold
in solution is subsequently separated from the original rock material of
the ore and recovered as gold metal.
The
four commonly used solvents that dissolve gold ore are hazardous and highly
toxic: Cyanide, which is used in gold mining worldwide, is extremely poisonous.
A few milligrams is fatal to humans. Mercury is hazardous as a vapor and
in water-soluble saltsand corrodes membranes of the body. Aqua Regia is
a concentrated mixture of hydrochloric and nitric acids that is toxic and
extremely corrosive. Thiourea is a potent thyroid poison for humans, and
recognized as potentially carcinogenic. Mercury amalgamation followed by
cyanide leaching came into widescale use in gold mining. The basic chemistry
regarding gold mining worldwide has changed little in over one hundred years.
Cyanide continues to be the method of choice by far even though it and other
toxic chemicals can contaminate the environment and kill.
The Opportunity
Technological
progress has enabled us to use natural resources more effectively and to
use the world's reserves to create new opportunities. Just as automation
revolutionized the manufacturing industry, Orex Gold Mines believes the
technology developed by Mr. Norman Haber will revolutionize the mining industry.
Orex
Gold Mines Corporation (Orex) has the unique opportunity to be the first
company to commercially use the "Haber Gold Process" (HGP) in
the U.S. as a non-hazardous alternative to cyanide leaching for gold. This
exciting new gold recovery process also enables gold to be recovered from
ores that the traditional method of cyanide leaching cannot treat. More
importantly, HGP is environmentally safe. Growing environmental concerns
about the use of cyanide have resulted in legislated prohibition (November
1998) against cyanide use for gold mining in Montana. Other stringent requirements
restricting cyanide use already exist in New Mexico, Oregon, Alaska, etc.
The successful employment of the HGP can bring a high profile of national
exposure to the Company.
The
project was ultimately presented to Mr. Norman Haber who reasoned that the
application of the HGP to alluvial and other kinds of gold deposits appear
to be realistic. On this basis, Mr. Haber has been willing to extend his
company's license for use of the Haber gold extraction technology. The specific
properties now under consideration are located in Arizona, Oregon, Montana,
and New Mexico, where cyanide permitting is virtually impractical today.
An
important feature of certain deposits under consideration, such as placers
or concentrates, is that they lend themselves to an early phase-in for gold
production. Once gold mining has begun, enhancement of production volume
can proceed.
The
evolution of modern engineering methods for mechanical concentration of
gold in placer deposits allows for low cost and efficient processing. Mechanical
processing of placer type ore gives gold recovery directly. Overall, this
enables very large volume production output of ore with relatively modest
capital expenditure and lower production costs. The direct gold recovery
merely requires the gold to be sent to the smelter for conversion to bullion
bricks.
The
placer type ores also carry gold in a form that is known as microfine gold.
The content of microfine gold in placer type deposits can reach 40-50%.
Microfines can normally not be readily processed. Even cyanide technology,
the standard for gold mine production worldwide, does not lend itself to
efficient recovery of microfine gold. This represents a substantial sacrifice
in recovery efficiency. Conversely, the HGP has a very high efficiency for
recovery with microfine gold. An HGP processing facility will allow the
selected gold properties to be the first for the use of a non-toxic recovery
method for placer gold in the United States. Deposits which previously were
unable to be mined due to their nature, location, or other problems with
the gold ore, can now be successfully removed. This will bring improved
recovery economics to the Company as well as possible broad attention because
of the non-toxic nature, speed and efficiency of gold recovery with the
use of the HGP.
The Haber Gold Process
Several
different mining groups were commissioned to investigate and review the
authenticity of the HGP and to report on its potential viability. These
tests yielded results that demonstrate the efficiency and the economic advantages
of the HGP over cyanide extraction.
Pincock,
Allen & Holt, Inc. made tests of the HGP on a 250 pound sample of Blackhawk
Mine ore. The results concluded that "the HGP offers various advantages
over present techniques and extracted gold in bulk in significantly less
time than is possible with cyanide. Recovery rates were exceptionally good,
particularly when compared to cyanide on the ores tested." It was determined
that using the HGP does not require any exotic equipment or hardware while
handling requirements for the chemicals used are significantly less stringent
than those practiced for cyanide. In the tests observed, the HGP extracted
89% of the gold from a low-grade ore from the Cripple Creek district of
Colorado and 93% of the gold in a high-grade ore concentrate from the Victorville
area of California. In both instances, leach time was completed in 6 hours.
PA
Technology Pty. Ltd. was commissioned to test the HGP for efficiency of
gold extraction and to report on its potential viability. Thus, 3 tonnes
of Australian gold bearing ore was prepared and shipped to the USA, where
a pilot test, in Tombstone, Arizona, was run under the control of PA Technology
Pty. Ltd., by Dr. William Jones. In order to make an accurate comparison,
the type of ore used was very conducive to gold recovery using cyanide.
The PA Technology pilot test concluded that HGP was effective for gold extraction
on an Australian oxidized gold ore in tonnage quantities. The extraction
of gold was 94% in 6 hours with the HGP, far superior to the 91% in 24 hours
for cyanidation. This was confirmed by independent assays. Maximum extraction
was reached 4 times faster with HGP versus cyanide leaching.
Comparison of HGP
with Cyanide Leaching
Independent
samples of the West Australian tonnage ore were extracted from the reaction
vessel and returned to Australia for assay by independent laboratories.
A sub-sample of the ore was leached by Ammtec, Inc. under their standard
cyanidation test conditions. The results from the HGP pilot plant in this
test displayed that a 91% gold extraction rate was achieved in just 4 hours.
Once again, cyanide leaching proved to be inferior as a 24- hour time period
was needed to reach the same 91% rate of gold extraction. In this test,
the results show that the HGP recovery rate was 6 times faster than cyanide,
and can accomplish in 4 hours what cyanide took 24 hours to accomplish.
Economic Benefits
Lyntek,
Inc. was also commissioned to perform a series of metallurgical tests with
the HGP. These tests, like the tests performed by Pincock, Allen & Holt
and PA Technology, determined actual recovery information and the efficiency
benefits to the HGP. Lyntek, Inc. also determined the economic advantages
of the HGP over conventional cyanide leaching. A significant difference
between the two leaching methods was the consumption of reagents. Cost per
ton of concentrate was approximately $60 with the cyanide method while the
HGP reagent cost less than $8 per ton. Leaching times were also significantly
slower using cyanide, with extraction taking approximately four times longer
to achieve similar results.
Seizing the Opportunity
With
favorable test results and pilot tests by reputable, world class, certified
mining engineering experts and companies, Orex is convinced that with the
HGP technology, it can rapidly launch itself into prominence in gold mining.
The
HGP has the ability to extract gold as efficiently or more efficiently than
cyanide; it has a recovery rate that is substantially faster than cyanide;
it has a chemical cost that compares favorably with cyanide; and it is environmentally
safe. Coupled with the increasing prohibitions against cyanide use, Orex
plans to seize this unique opportunity and be the first company in the U.S.
to commercially utilize the HGP.
Recent Investor Highlights
Although
Orex has traded publicly for only a few months, the company has already
begun to take the initial steps needed toward achieving their goals of becoming
fully reporting and listing the stock on a higher exchange. The company
seems to be gaining national attention in both printed and Internet media
coverage. Written articles on Orex have appeared in "Business Week"
(April 19, 1999; page 156), "Mining Stock Digest" (April 1999),
and "Financial Sentinel" (May/June 1999). SmallcapNewswire.com,
a financial news portal, became the first Internet site to initiate coverage
of Orex as a "feature company" on July 26, 1999.
