The claims are situated on the north-west extension of a system of multiple northwest-southeastern trending parallel structures that could be part of the La Sierra vein system.
La Sierra is the most easterly of the three structural systems in the prolific Guanajuato district along with the main Veta Madre and the La Luz trends, the company said.
At present, the company is mining on the Veta Madre system at its Guanajuato Mine and exploring on the westerly La Luz system at the San Ignacio project.
Great Panther said that through the course of due diligence, it has already completed considerable ground work on the Santa Rosa claims.
Multiple veins have been identified, with argillic alteration and erratic silver and gold values.
According to the company, potential drill sites are being investigated to test the various structures.
