VANCOUVER, BC, April 11,
2023 /CNW/ - Pan Global Resources Inc. ("Pan Global"
or the "Company") (TSXV: PGZ) (OTCQB: PGZFF) is pleased to announce
successful results for preliminary metallurgical test work from the
La Romana copper-tin-silver discovery in the Escacena Project,
Spain. The metallurgical test work reported today was
completed by Wardell Armstrong International (United Kingdom), under the coordination and
management of SCYPI (Spain).

"The high copper recoveries and concentrate grades achieved at
this early stage are highly encouraging. It is not just the
recoveries and concentrate grade that makes these results very
good, it's the combination along with low deleterious metals and
coarse primary grind size, particularly when compared to what we
know of the other deposits in the area, and potential for lower
final energy consumption. We are looking forward to the results
from the ongoing tin metallurgy test program and variability tests
on the copper and tin mineralization from different parts of La
Romana, including areas of higher grade mineralization," said
Tim Moody, Pan Global's President
& CEO.
The metallurgical testing program was conducted using
representative core from the 2022 La Romana drilling campaign to
establish copper recoveries and concentrate grades. Whilst the
metallurgical test work is ongoing, the results achieved for the
first phase of testing demonstrate the potential for a conventional
flotation process flowsheet capable of recovering copper into a
saleable concentrate.
In its report, SCYPI commented: "As compared to the average of
the Pyrite Belt deposits, La Romana mineral has shown lower energy
requirements for crushing and grinding and better flotation process
performance for copper (both concentrate grade and recoveries)
using conventional circuits and chemical agents, anticipating
moderate operating costs related to the process." In addition:
"Pending receipt of the detailed analysis of the concentrates, the
low grade of deleterious elements (As, Sb, Bi, Hg, Cl and F)
together with additional credits from Ag, will contribute to a
higher NSR value."
Tests indicate a potential Bond Ball Mill Work Index of 15.6
kWh/t, Bond Rod Mill Work Index of 13.5 kWh/t, Abrasion Index of
0.088 and Bond Crusher Work Index of 24.25 kWh/t. The size
distribution of the chalcopyrite for the representative sample used
for these tests shows a grind size P80 in the range of 150μm and
liberation analysis indicates 65% of the mineral is well liberated
below 106μm. These encouraging results indicate the potential for
lower energy requirements which will have a positive impact on
future operating costs.
The metallurgical test program was conducted on representative
samples involved a series of copper (Cu) rougher and cleaner tests
commencing with a head grade of 0.39% Cu, culminating in two locked
cycle flotation tests (LCT) designed to assess and replicate, on a
bench scale, potential full-scale flotation flow sheet options.
LCT1 achieved a 86.4% Cu recovery and copper concentrate grading
28.5%, and LCT2 achieved a higher Cu recovery of 89.5% and a copper
concentrate grade of 23.8%.
The test results to date indicate that a simple conventional
flotation process flowsheet will be suitable for the La Romana
copper mineralization. Follow-on work will include
settling/dewatering tests and environmental characterization tests.
A tin metallurgy program has also commenced to determine processing
and recovery options using representative samples from drill core
in the areas of La Romana that reported higher grades of tin. A
variability test work program is also planned on samples from
various parts of the deposit with varying copper and tin grades,
including the higher grade parts of the deposit.
Pan Global believes the results from the metallurgical test work
further reinforce the positive attributes of the Escacena Project.
Together with the ongoing test work, these results will form the
basis for advancing the La Romana discovery towards a resource and
future Preliminary Economic Assessment.
Three drill rigs have been operating in 2023 at the Escacena
Project. The final hole is in progress on a planned 10-hole infill
plus step out drill program at the La Romana discovery. Results for
the first three drill holes at the Romana Deep target are expected
to be reported shortly and drilling at the Zarcita target is
ongoing with additional results are anticipated over the coming
weeks.
Pan Global is also pleased to report that discussions are
advancing with local land owners on access to potential near
surface extensions of the La Romana mineralization along strike to
the west and to the east, which remain untested.
About the Escacena
Project
The Escacena Project comprises a large, contiguous,
5,760-hectare land package controlled 100% by Pan Global in the
east of the Iberian Pyrite Belt. The project is located near
operating mines at Las Cruces and Riotinto and is immediately
adjacent to the former Aznalcóllar and Los Frailes mines where
Minera Los Frailes/Grupo Mexico is in the final permitting stage
with construction anticipated to restart in 2023. The Escacena
Project hosts the La Romana copper-tin discovery and a number of
other prospective targets, including Zarcita, Hornitos, La Jarosa,
Romana Deep, Bravo, Barbacena, El Pozo, and San Pablo.
