Lakewood, Colorado / ACCESSWIRE / March 31,
2014 / Taranis ("Taranis") [TSX.V: TRO] has completed
a preliminary metallurgical assessment on samples from the Thor
Project located near Trout Lake, British Columbia. The
metallurgical tests were conducted by ALS Metallurgy-Kamloops on
two separate portions of the deposit including the main historic
sulphide deposit containing silver, lead, zinc, gold and copper and
the new Gold Zone known as SIF. ALS has also completed Acid-Base
Assessment labwork of the ore that help characterize the ores and
the associated waste products.
The Gold Zone
There is a considerable amount
of outcropping gold mineralization in an area located immediately
west of the known sulphide deposit that has not been outlined in
the existing NI 43-10 Resource, and it is contained almost entirely
within quartz-bearing zones. A 117.7 kg composite sample was
collected from the SIF gold occurrence and served as the bulk
metallurgical sample for the Gold Zone. The head grade was
identical to that sampled during the Taranis panel sampling program
in summer 2013:
Head Grade for
the Gold Zone Metallurgical Sample
--------------------
|S(%)|Fe(%)|Au(g/t)|
|------------------|
|0.04|1.07 |15.5 |
--------------------
Three separate processes to
extract gold from the sample were tested: gravity concentration,
flotation and cyanide leaching. Gravity recovery in the Gold Zone
using a Knelson concentrator yielded 83% gold recovery to a
concentrate grading 715g/tonne gold. Similarly, flotation recovered
97% gold from the feed to a concentrate grading 219 g/tonne gold.
Cyanide leaching showed recoveries of 93% after 6 hours and 98%
after 24 hours (ore ground to a nominal
67?m K80 for
all tests). The positive results from flotation gravity and
flotation process are encouraging as these processes are low cost
and have less environmental impact when compared to cyanide
leaching.
The
Sulfide (Silver-Lead-Zinc) Zone
Representative drill core from
eighteen different drill holes were taken from the deposit at Thor
and used for the metallurgical testing of the Sulphide Zone. The
head grade for the metallurgical sample analyzed by ALS is shown in
the following table:
Head Grade for
the Sulfide Zone Metallurgical Sample
----------------------------------------------------
|Cu |Pb(%)|Zn(%)|Fe(%)|S(%)|Ag |Au |Total |
|(%) | | | | |(g/t)|(g/t)|Organic |
| | | | | | | |Carbon (%)|
|--------------------------------------------------|
|0.15|3.29 |4.38 |15.2 |10.8|206 |1.36 |0.34 |
----------------------------------------------------
This composite metallurgical
sample was very close to the actual average grade of the deposit.
The NI 43-101 for the Sulphide Zone outlined the following Resource
(for more details, see the Taranis News Release dated June 20,
2013) of which about 70% is potentially open-pittable.

Rougher and cleaner tests were
performed on the Sulphide Zone and utilized a conventional bulk
lead flotation followed by a zinc flotation circuit, (ore ground to
a nominal 97?m
K80.) A limited number of optimization
tests were performed, the best test results were from batch cleaner
test 11. The bulk concentrate from test 11 had the following grades
and recoveries:
Recoveries in
Bulk Lead Concentrate
------------------------------------------
|Metal |Grade (% or g/tonne)|Recovery (%)|
|----------------------------------------|
|Lead |51 |86 |
|----------------------------------------|
|Silver|2,620 |65 |
|----------------------------------------|
|Gold |13 |56 |
|----------------------------------------|
|Zinc |8 |10 |
|----------------------------------------|
|Copper|1.4 |45 |
------------------------------------------
Note: Gold and silver grade are in
g/tonne, all others are in percent.
The zinc concentrate that had
the following grades and recoveries:
Recoveries in
Bulk Zinc Concentrate
------------------------------------------
|Metal |Grade (% or g/tonne)|Recovery (%)|
|----------------------------------------|
|Lead |1.6 |3 |
|----------------------------------------|
|Silver|205 |5 |
|----------------------------------------|
|Gold |0.9 |4 |
|----------------------------------------|
|Zinc |58 |65 |
|----------------------------------------|
|Copper|0.4 |11 |
------------------------------------------
Note:
Gold and silver grades are in
g/tonne, all others are in percent.
The
silver and gold reporting to the bulk concentrate is an ideal
situation to maximize the pay-back of the precious metals in the
Sulphide Zone. The copper content is not of sufficient tenor at
this time to warrant recovery. It is important to note that the
results are based on batch test results. There is considerable
potential to increase the metal recovery of zinc to the zinc
concentrate by further reagent optimization and conducting closed
circuit locked cycle tests.
General Comments
The metallurgical work completed at Thor is part of a larger 5
phase plan designed to permit and develop the Thor deposit (Taranis
News Release Dec 11, 2013). Taranis has also applied for a Special
Use Permit for the main access road to the property.
The next stage in the plan is the delineation of surface Gold
Zone estimated to be 24,393 m2 in area lying
immediately west of the Sulphide Zone. Taranis is confident that it
can build an NI 43-101 compliant gold Resource occurs in this
vicinity. Panel sampling on isolated outcrop areas have obtained
results including 21.25 g/t Au over 11.45 m (Taranis News Release,
September 19th, 2013), and has also yielded widespread
gold values in surface grab sampling.
