Toronto, Ontario — December 18, 2025 — Leads & Copy — Palamina Corp. has acquired 100% of the mineral rights to the Esperanza concession, a 60.75 hectare area in the Santa Lucia district of southeastern Peru. The concession was acquired for US$18,000 outright, with no royalties payable on the property.
Esperanza is adjacent to Aftermath Silver Ltd.’s Berenguela silver copper manganese project, which covers approximately 50 hectares and hosts a mineral resource estimate of 122.5 million ounces of silver in the Measured and Indicated categories, with an additional 22.0 million ounces in the Inferred category.
According to Andrew Thomson, President of Palamina, the company has increased its land position in the Santa Lucia district by over 1,460 hectares in the last month via staking and acquisition. He added that approximately half of the surface area at Esperanza shows the same geology and copper manganese mineralization as the Berenguela deposit.
Palamina previously conducted a remote sensing study over the Santa Lucia district to enhance its understanding of regional geology. The results of that study, along with a recent site visit, suggest Esperanza could host an extension to the Berenguela deposit. Palamina is currently focused on advancing its Galena silver copper manganese project, located along the same geological trend, through the drill discovery phase.
A recent field visit to Esperanza by Palamina’s geological team identified the same outcropping limestone unit that hosts mineralization at the adjacent Berenguela deposit. At Berenguela, mineralization occurs within carbonate rocks of the Cretaceous Ayabacas Formation, which is tightly folded and trends northwest-southeast into the Esperanza concession.
High-grade silver copper manganese mineralization at Berenguela occurs predominantly as manganese-rich gossans replacing the carbonate sequence.
Palamina commissioned ALS Goldspot to acquire and process WorldView-3 data to generate a hyperspectral map of the 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 a key pathfinder at Palamina’s Galena silver copper manganese project and at the nearby historic Santa Barbara and Berenguela CRD 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 detailed geological mapping and sampling at Esperanza in early 2026.

Palamina Corp. is an exploration company with gold projects in the Puno Orogenic Gold Belt and copper-silver assets in southeastern and northeastern Peru.
