- High tin concentrate grades of 63.2% at recovery rates of
64% calculated from conventional gravity processing
- Low levels of penalty elements
- Gravity concentration test results show significant
additional tin recovered from the tails, increasing overall tin
recovery by 10%
- Excellent tin metallurgy results value-adding for La Romana
economics
VANCOUVER, BC, Dec. 11,
2024 /CNW/ - Pan Global Resources Inc. ("Pan Global"
or the "Company") (TSXV: PGZ) (OTCQX: PGZFF) (FRA: 2EU) is pleased
to announce positive metallurgical test results from the second
phase tin metallurgy test program, with the successful recovery of
additional tin from the gravity tailings at the La Romana
copper-tin-silver discovery in the Escacena Project, southern
Spain.
"The testwork on the La Romana mineralization continues to
produce excellent metallurgy results for both copper and tin that
stand out relative to other mines on the Iberian Pyrite Belt. The
new metallurgy tests were highly successful, confirming that
additional tin can be recovered from the gravity tails that would
otherwise be lost. The tests show La Romana tin mineralization is
well suited to conventional gravity separation to produce
high-quality, marketable tin concentrate. These results further
enhance our view that the tin mineralization could meaningfully add
to the overall project economics and de-risking," said Tim Moody, Pan Global's President & CEO.
Key Results:
- A premium high-grade tin concentrate is achievable using
conventional gravity separation techniques
- Additional tin concentrate can be efficiently recovered from
the gravity tails after both rougher and cleaner stage processing
using a shaker table and Multi-Gravity Separator
- Tin recoveries of 63.9%, representing a 10% overall increase on
previous estimates with additional tin recovered from the gravity
tails
- High tin concentrate grades of 63.2%
- Chemical analysis of the final tin concentrates confirmed low
levels of deleterious elements such as arsenic, mercury, and
antimony that might incur refining penalties
- Simple processing flowsheet with conventional gravity
separation for tin and flotation for copper requiring less
energy-intensive fine grinding compared to mines in the area
- Metallurgy work has been done to a level adequate for
Preliminary Economic Assessment
- Next steps could include closed-circuit testing, such as pilot
plant trials on larger volumes of material to optimize concentrate
grades and recoveries for pre-feasibility/feasibility studies.
The testwork was conducted by Wardell Armstrong International
(United Kingdom), under the
coordination and management of Minepro Solutions SL (Spain). The new results complement the
previous positive metallurgy testwork on La Romana
copper/tin/silver mineralization that showed the potential to
produce high quality, clean, saleable copper concentrate by
conventional flotation, and produce premium quality, high-grade tin
concentrate with good recoveries by conventional gravity separation
(see media releases dated March 21,
2024 and April 3,
2024),
Second Phase Tailings Testwork Program for Tin
The purpose of this program was to investigate the potential for
recovering additional tin from the fine fractions of the gravity
tailings after initial processing, and also enhance the overall
efficiency of the recovery process and economics of the
project.
Initial gravity separation tests proved significantly more
effective for recovering tin from tailings compared to flotation
methods. Detailed gravity separation tests on the gravity tails
were then conducted on two size fractions: coarser (-53+38 microns)
and finer (-38 microns). The coarser fraction was processed using
conventional shaker tables and the finer fraction was processed
using a Multi-Gravity Separator, to produce tin concentrates after
both rougher and cleaner stages, and recirculation to enhance the
overall recovery efficiency. See Figure 1 below.
Closed-circuit interpretation results
All the metallurgical testwork to recover tin concentrates has
been under open-circuit conditions where a portion of tin may be
lost or unaccounted for, either as middlings or tailings products.
Following the success in recovering additional tin from the finer
fraction of the gravity tails, a mass balance calculation was
performed by Minepro to simulate what might be achieved under
closed-circuit conditions.
The mass balance calculation gave a projected final tin
concentrate grade of 63.2%, and tin recovery rates of 63.9%. The
calculation is based on the open-circuit results and similar
deposits in the Iberian Pyrite Belt, assuming tin recoveries of 90%
from the middlings and 25% from tailings. These results will be
verified in further testing, including closed-circuit testing, such
as pilot plant trials.
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. Escacena is located near the
operating mine at Riotinto and is immediately adjacent to the
former Aznalcóllar and Los Frailes mines where Minera Los
Frailes/Grupo México is in the final permitting stage to allow new
mine construction to commence. The Escacena Project hosts Pan
Global's La Romana copper-tin-silver and Cañada
Honda copper-gold discoveries, and a number of other
prospective targets, including, Bravo, Barbacena, El Pozo,
Romana Norte, San Pablo, Zarcita,
Hornitos, La Jarosa, Romana Deep,
and Cortijo.
