NanoStruck Technologies Inc. (the “Company” or “NanoStruck”)
(CSE:NSK) (OTCQX:NSKTF) (Frankfurt:8NSK) announces testing of its
mine tailings treatment techniques and preliminary results showing
recovery rates of gold from mine tailings to be much higher than
expected by industry observers. NanoStruck’s techniques involve
nanotechnology and industrial collaboration for specific innovative
milling, pryometallurgy and hydrometallurgy processes
combined with proprietary organic compounds.
Tests completed over the past three months indicate that the
Nanostruck techniques can recover as much as 96% of 9.1 grams
per metric ton, or 0.32 ounces per ton, of gold contained in
representative gold tailings samples. The testing involved careful
roasting of tailings in laboratories. When the Nanostruck
techniques were applied to tailings that had been previously
roasted at the source site, the recovery rate was 88%, multi-fold
higher than previous attempts by other companies using alternative
technologies such as cyanide leaching. From the same already
roasted sample, for example, conventional Carbon In Leach (CIL)
processes had resulted in less than 10 percent recovery of gold.
The volume of tailings at the source site, which is owned by an
unrelated third party, is estimated to be between 450,000 tons and
500,000 tons. NanoStruck is in discussions with the owners of the
source site regarding potential contracts for processing the mine
tailings at the source site.
The head assays and sampling were done by SGS SA and optical
microscopic study performed by Petrolab Ltd to verify the
representativeness of the tailing samples as well as percentage of
precious metal contained in them. Recovery rates and processes used
were also monitored and verified by certified third party experts
and laboratory testing, including electron microscope analysis.
The value of precious metals left in mine tailings in 2012 alone
by mining companies such as Anglo American Plc (LON: AAL), Barrick
Gold Corp. (TSX: ABX, NYSE: ABX), Goldcorp Inc. (TSX: G, NYSE: GG)
and Rio Tinto Group (ASX: RIO), was estimated to be US$20 billion
at current market prices. Of that, gold represented more than 80%
of the value with approximately 360 tons of gold left behind in
tailings due to their micronic size, complex minerology as well as
political and environmental concerns related to cyanide
leaching.
NanoStruck’s environmentally conscious approach did not involve
the use of cyanide leaching. All chemicals and organic substances
used were recycled and reused.
More details on the refractory gold tailing samples and
specifics of the results will be published in the weeks ahead along
with highlights from an environmental impact study as well as a
volumetrics and grade survey.
Bundeep Singh Rangar, interim CEO and Chairman of the Board
said: "We are very excited to announce these tremendously high
recovery rates, involving non-cyanide hydrometallurgy and
nanotechnology based processes, that could be transformative for
the mining industry.”
Brian Mok, Senior Mining Consultant at BG Partners Corp. said:
“High value refractory ore and tailings would be very well suited
for this process as well as jurisdictions where the use of toxic
materials such as cyanide is undesirable or unacceptable.”
About the Company
NanoStruck Technologies Inc. is a Canadian Company with a suite
of technologies that remove molecular sized particles using
patented absorptive organic polymers. These versatile biomaterials
are derived from crustacean shells or plant fibers, depending on
requirements of their usage. Acting as molecular sponges, the
nanometer-sized polymers are custom programmed to absorb specific
particles for remediation or retrieval purposes. These could be
used to clean out acids, hydrocarbons, pathogens, oils and toxins
in water via its NanoPure solutions. Or to recover precious metal
particles in mine tailings, such as gold, silver, platinum,
palladium and rhodium using the Company’s NanoMet solutions.
By using patented modifications to conventional technologies and
adding polymer-based nano-filtration, the Company’s offers
environmentally safe NanoPure solutions for water purification. The
Company uses Environmental Protection Agency (EPA) and World Health
Organization (WHO) guidelines as a benchmark for water quality and
safety to conform to acceptable agricultural or drinking water
standards in jurisdictions where the technology is used.
Additionally, the Company’s technology can be used to recover
precious and base metals from mine tailings, which are the residual
material from earlier mining activities. By retrieving valuable
metals from old tailing dumps, the Company’s NanoMet solutions
boosts the value of existing mining assets and reduces the need for
new, costly and potentially environmentally harmful exploration and
mining.
The Company’s current business model is based on either selling
water remediation plants or leasing out units and charging
customers on a price per liter basis with a negotiated minimum
payment per annum. For processing mine tailings, the value of
precious metal recovered is shared with tailing
site owners on a pre-agreed basis.

of any of the words "anticipate", "continue", "estimate", "expect",
"may", "will", "project", "should", "believe" and similar
expressions are intended to identify forward-looking statements.
Statements relating to "reserves" or "resources" are deemed to be
forward-looking statements because they involve the implied
assessment, based on certain estimates and assumptions that the
resources and reserves described can be profitably produced in the
future. Forward-looking statements in this press release include
that of the precious metals left in mine tailings by the companies
listed above, gold represented more than 80% of the value with
approximately 360 tons of gold left behind in tailings and that
more details on the refractory gold tailing samples and specifics
of the results will be published in the weeks ahead along with
highlights from an environmental impact study as well as a
volumetrics and grade survey.
Although the Company believes that the expectations and
assumptions on which the forward-looking statements are based are
reasonable, undue reliance should not be placed on the
forward-looking statements because the Company can give no
assurance that they will prove to be correct. Since forward-looking
