GT Gold Corp. (TSX-V:GTT)
(the
“Company” or “GT Gold”) is pleased to announce the
results for initial metallurgical testwork on two composite samples
from the Saddle North Cu-Au porphyry discovery on its 100% owned
Tatogga project in northwest British Columbia.
Highlights
- High-grade composite recovered 88%
of the copper and 67% of the gold in a concentrate that graded
24.5% Cu and 32.2 g/t Au
- Lower-grade composite recovered 75%
of the copper and 57% of the gold in a concentrate that graded
22.0% Cu and 23.3 g/t Au
- Potential for a simple,
conventional flowsheet
“These results further de-risk the project,
which bodes well for our ongoing economic, diagnostic and
optimisation work as part of the studies to complete a Preliminary
Economic Assessment by year end,” said Paul Harbidge, President and
CEO.
The Company has conducted initial metallurgical
testwork on two composite samples; the first from the broad
envelope of mineralization grading >0.25% CuEq, and the second
from the deeper high-grade core of mineralization grading >1%
CuEq. The metallurgical testwork was conducted by Blue Coast
Research Ltd., Parksville, BC.
Composite Sample from the High-grade
Core
The high-grade composite sample of 53 kg was
collected from the deeper, high-grade mineralized core, comprising
diamond drill core assay values >1% CuEq. The composite had an
average grade of 0.92 g/t Au, 0.50% Cu and 1.56 g/t Ag (Table
1).

Composite Sample from the Broad Envelope
of Mineralization
A composite sample of 95 kg, was collected from
within the broad mineralized envelope, comprising borehole
intervals having assay values >0.25% CuEq. The composite was
made of samples from intervals in ten boreholes that were drilled
during the 2018 drilling campaign.
The composite sample had an average grade of
0.45 g/t Au, 0.30% Cu and 2.27 g/t Ag (Table 2).

Flotation Testwork
A flotation testwork program was conducted to
evaluate flowsheet requirements necessary to produce a copper
concentrate of acceptable grade. A conventional flowsheet was
employed during the testwork consisting of copper rougher
flotation, followed by concentrate regrinding and three stages of
cleaner flotation. During the flotation program several
salient features were noted:
- Primary grinds of 80% passing
~150μm could be employed without significant impact to copper and
gold recovery;
- Rougher pH of 10.5 and cleaner pH
of 11 to 11.5 increased depression of pyrite resulting in the
production of higher-grade concentrates; and
- Three stages of cleaning were
necessary to achieve target concentrate grades.
The flotation program culminated with a locked
cycle test on each composite. Locked cycle testwork on the
material from the high-grade core produced a concentrate grading
24.5% Cu and 32.2 g/t Au. Copper and gold recovery to the
final high-grade concentrate was 88% and 67% respectively.
Testwork on the lower grade material collected from within the
broad envelope of mineralization produced a concentrate grading
22.0% Cu and 23.3 g/t Au. The testwork on the broad envelope
composite supports an overall recovery of 75% Cu and 57% Au.

Three further composite samples are being
collected for comminution testing, with results expected to be
received in Q3 2020. Two of the composite samples are within the
potential open pit limits with one sample from the broad envelope
of mineralization and the second from the high-grade core. The
third composite sample is being collected from the deeper
high-grade core of mineralization that has underground mining
potential.
Saddle North Progressing toward a
Preliminary Economic Assessment
In terms of other work progressing on the
project, a 31,163 metre relog of the Saddle North core has now been
completed and the data is being compiled into a geological model,
which is on track for completion at the end of Q1 2020. This model
will form the foundation for an initial resource estimate in Q2
2020. At the same time, engineering work and studies are ongoing to
deliver the Preliminary Economic Assessment (PEA) in Q4 2020.
