Golden Tag Reports Positive Metallurgical Test Results From Fernandez Zone
21 9월 2022 - 8:30PM
Golden Tag Resources Ltd. (“
Golden Tag” or the
"
Company") (TSX.V: GOG) (OTCQB: GTAGF) is pleased
to provide metallurgical test results from mineralization contained
within the Fernandez Zone, located on the Company’s 100% owned San
Diego Project, in Durango Mexico.
Highlights include:
- First ever metallurgical
results performed on the Fernandez Zone demonstrates Endoskarn
mineralization is amenable to conventional flotation
techniques
- 76% of the Ag and 84% of
the Pb were recovered to a bulk concentrate containing 51%
Pb, 4700 g/t Ag, 3.11% Zn, 5.27%
Cu, and 2.23 g/t Au
- Cu and Au recoveries within
the bulk concentrate had significant improvements over previous
test work
- 84% of the zinc was
recovered to a concentrate grading 47% zinc
Greg McKenzie, President and CEO commented: "We
are pleased to have completed the first ever metallurgical test
results from within the Fernandez Zone. The results reported today
indicate conventional flotation techniques could be utilized to
produce a commercial saleable concentrate from a sample taken from
the Fernandez Zone, in particular within the Endoskarn
mineralization.
When we compare these results with previous test
work performed on other zones at San Diego, we are encouraged by
the improvements within the bulk Pb concentrate, in particular the
Ag concentrate grade as well as higher recoveries of Au and Cu.
Typical reagent regimes and grind size (P80 109
µm) were used in the testing, and we are confident that additional
test work and applied optimization could result in additional
improvements in recoveries and concentrate grades. Additional
metallurgical test work is being planned to be performed in
2023.”
Summary of Metallurgical Test
Work
The metallurgical test work was conducted by ALS
Metallurgy in Kamloops, BC under the direction of Adam Johnston of
Transmin Metallurgical Consultants. Six samples of ¼ drill core
taken over 6 metre intervals were selected from three drill holes
completed within the Fernandez Zone, designed to be representative
of the Fernandez Zone lithologies and geochemistry. The samples
were subjected to detailed mineralogy, including mineral
assemblage, texture, and mineral liberation assessments at ALS. The
samples were analyzed using a Trace Metal Search (TMS) technique
focused on silver which concluded that silver is mainly present as
freibergite. A 27-kilogram composite (SAC-001) of four samples from
the Endoskarn Zone was analyzed by Particle Mineral Analysis (PMA)
to determine mineral liberation parameters prior to proceeding with
flotation tests. The flotation development comprised the evaluation
of rougher and cleaner stages and an open circuit flowsheet was
established using conventional reagents and techniques.
Approximately 76% of the Ag and 84% of the Pb were recovered to a
bulk lead concentrate grading approximately 4700 g/t silver, 51%
Pb, 3.1% Zn, 5.3% Cu, and 2.23 g/t Au (Table 1).
As compared to the metallurgical test results
established in the NI 43-101 Technical Report Mineral Resource
Estimate prepared by SGS Canada effective April 2013, this initial
test work has improved predictions for the silver recovery from 71%
to 76% in the bulk Pb concentrate, while increasing the concentrate
grade from 3623 g/t Ag up to 4700 g/t Ag, and demonstrated
substantial improvements in Cu and Au recoveries. There was also an
improvement in the predicted zinc recovery from 81% to 84% in the
zinc concentrate.
Additional metallurgical test work is required
to further optimize the flotation conditions before proceeding with
locked cycle testing.
