DEPOSIT, SPAIN
TSXV: PGZ | OTCQX: PGZFF | FRA: 2EU
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

/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 (

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.
About Pan Global Resources
Pan Global Resources Inc. is actively targeting copper-rich mineral deposits, given copper's compelling supply-demand fundamentals and outlook for strong long-
term prices as a critical metal for global electrification and energy transition. The Company's flagship Escacena Project is located in the prolific Iberian Pyrite Belt
in southern
Spain
, where a favourable permitting track record, excellent infrastructure, mining and professional expertise, and support for copper as a Strategic
