Independence Gold Recovers Up To 99.5% Gold From Merit Property, British Columbia
November 28 2019 - 8:30AM
Independence Gold Corp. (TSX.V:
IGO) ("Independence" or "the Company") is pleased to
the announce results from an Early Stage Metallurgical Study
(“ESME”) carried out on auriferous vein material collected from the
Sullivan Ridge Target at the Merit Property (“the Property”),
British Columbia. The study, comprised of two composite vein
samples recovered 99.5% and 96.6% gold, respectively, through a
three-stage process of gravity separation, flotation and leaching,
indicating favourable mineralogy for further exploration.
Sample Selection and
PreparationComposite samples composed of chalcedonic
quartz were collected from two separate veins at the Sullivan Ridge
Target. These veins yielded gold assay values up to 9.5 grams per
tonne (“g/t”) from samples collected earlier in the season (see
news release dated November 4th, 2019) and are considered
representative of the Property.
Samples were submitted to SGS Labs in Burnaby
for testing. They were initially crushed to 100% passing 10-micron
mesh, then each sample was blended and rotary split into
two-kilogram test charges for the metallurgical testing. A 100g
sub-sample was also separated using a riffle splitter and submitted
for chemical head assays including gold, copper and total sulphur,
as well as for head mineralogy study.
Head ResultsThe following table shows the
assays results for both samples and appear to show some level of
“nugget” distribution in the samples as expected.

The mineralogy of the two samples were studied
using QEMSCAN Particle Mineral Analysis (PMA), and indicated the
main sulphides present are pyrite and marcasite, with copper being
mostly native.
Gravity SeparationA single
gravity separation test was completed on each composite to evaluate
the potential for gravity recoverable gold and silver using a
Knelson concentrator. The concentrate was submitted for assaying
and the tailings used for floatation testing. Gravity methods
managed to recover 50.7% gold and 66.6% silver in ESME 1, and 62.2%
and 38.8% silver in ESME 2.
Floatation TestworkA single
test was conducted on each of the gravity tailings to assess
further recoverability of gold and silver, with the concentrate
being submitted for assaying and mineralogy. From these tailings,
ESME 1 recovered 74.9% gold and 85.3% of the silver remaining in
the stream. ESME 2 recovered 63.4% gold and 50.2% silver.
Cyanide LeachingThe floatation
tailings were submitted for bottle roll cyanide leaching tests,
lasting for 48-hours with a pH of 10.5 to 11. Both composites
performed well and recovered additional gold in the pregnant leach
solution. ESME 1 recovered 96.3% gold from the floatation tailings,
while ESME 2 recovered 75.4% gold.
Product MineralogyIn both samples, gold occurs
as either native gold or electrum. Other minerals of note include
hessite (silver telluride) and acanthite (silver sulphide).
Overall ResultsThe following
table summarizes the results of the ESME test work. It is believed
that recoverability could be further improved by modifying the
processes, but the initial high recovery amounts increase
confidence in future exploration of the multiple gold zones on the
Property. It was also found that the final tailings are not acid
producing, which is key in future environmental considerations.
