Palamina Acquires Esperanza Project South East of the Berenguela Silver-Copper-Manganese Deposit
PALAMINA ACQUIRES ESPERANZA PROJECT SOUTH EAST OF
THE BERENGUELA SILVER-COPPER-MANGANESE DEPOSIT
FOR IMMEDIATE RELEASE
December 18, 2025
Palamina Corp. (TSXV: PA; OTCQB: PLMNF) has acqui red 100% of the mineral rights to the Esperanza
concession covering a 60.75 hectare area located in the Sa nta Lucia district in southeastern Peru. Esperanza
lies adjacent to Aftermath Silver Ltd.’s (TSXV: AMM) Berenguela silver copper manganese project which is
hosted within a surface area of approximately 50 hect ares. Berenguela hosts a current mineral resource
estimate of 122.5 million ounces of silver in the Measu red and Indicated categories and an additional 22.0
million ounces silver in the Inferred category. Palamina acquired the concession for US$18,000 outright with
no royalties payable on the property.
Andrew Thomson, President of Palamina, commented: “In the last month Palamina has increased its land
position in the Santa Lucia district by over 1,460 hect ares through staking and acquisition. Roughly half of
the surface area at Esperanza exhibits the same geology and copper manganese mineralization found at surface
at the Berenguela deposit to the north west. Prior to acquiring Esperanza, Palamina concluded a remote
sensing study over the Santa Lucia district in order to better understand regional geology. This study, along
with a recent site visit, would suggest that Esperanza has the potential to host an extension to the Berenguela
deposit. Palamina is focused on adva ncing its Galena silver copper manga nese project, located in the same
northeast southwest geological trend, through the drill discovery phase.”
.
A recent field visit at Esperanza, conducted by Palami na’s geological team, identified the same outcropping
limestone unit that hosts mineralization at the adja cent Berenguela deposit. At Berenguela, mineralization
occurs within carbonate rocks of the Cretaceous Ayabacas Formation, which is tightly folded and trends NW–
SE into the Esperanza concession. High-grade silver copper manganese mineralization at Berenguela occurs
predominantly as manganese-rich gossans replacing the carbonate sequence.
Geological Summary and Next Steps
Palamina commissioned ALS Goldspot to acquire and process WorldView-3 data to generate a hyperspectral
map of the whole Santa Lucia district. Initial results confirm that manganese minerals are the primary
pathfinders for CRD-type mineralization in the region and that the main Berenguela manganese trend extends
into the Esperanza concession.
Manganese is also the key pathfinder at Palamina’s 100%-owned Galena silver copper manganese project and
at the nearby historic Santa Barbara and Berenguela CR D mines. At Galena, recently released soil sampling
results show that strong manganese anomalies coincide with outcropping silver and base-metal mineralization
(NR December 1, 2025). Palamina plans to conduct de tailed geological mapping and sampling at Esperanza
in early 2026.
