VANCOUVER, British Columbia -- (Business Wire)
NanoStruck Technologies Inc. (the “Company” or “NanoStruck”) (CSE:NSK)
(OTCQX:NSKTF) (Frankfurt:8NSK) is pleased to announce positive results
from test work carried out on silver mine tailings utilizing proprietary
cyanide free recovery technologies that returned up to 87.6% of silver
from samples grading 56 grams of silver per metric ton (g/t).
Three leach tests were conducted using the proprietary mixed acid leach
process. Roasting was conducted on the sample for two of the leach
tests, producing higher recoveries, although the un-roasted sample still
produced a 71% recovery rate.
1. 87.6% silver recoveries resulted from a 4 hour leach time at 95
degrees Celsius, with the standard feed grind size of D80 175 micron of
roasted material.
2. 84.3% recoveries resulted from a 4 hour leach at 95 degrees Celsius
with the standard feed grind size of D80 175 micron with roasted
material at a lower acid concentration.
3. 71% recoveries resulted from a 4 hour leach at 95 degrees Celsius
from received material, with the standard feed grind size of D80 175
micron with an altered acid mix concentration.
The average recovery for the roasted samples was 86% across the two
leach tests performed using the proprietary process.
Bundeep Singh Rangar, Interim CEO and Chairman of the Board, said:
"These results further underpin the effectiveness of our processing
technology. With our patented process we are achieving excellent
recoveries in not only silver tailings, but also gold tailings as well,
both of which have vast global markets for us.”
The proprietary process combines a novel mixed acid leach with a solvent
extraction stage, utilizing specific organic compounds. No cyanide is
used in this environmentally friendly process. The flow sheet design is
for a closed loop, sealed unit in which all chemicals are then recycled.
Previous test work undertaken on other gold mine tailings utilizing the
proprietary process resulted in a maximum 96.1% recovery of gold.
Previous test work undertaken on other silver tailings resulted in a
maximum 86.4% recovery of silver.

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 the 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.
