The latest results have identified a new high-grade mineralized shoot north of the historical Aguilareña shaft that hosts the highest gold and silver grades over some of the widest intervals drilled on the property to date. Drill Result Highlights (Estimated True Widths) 4.44 m @ 8.00 g/t Au and 65 g/t Ag (754 g/t AgEq*) from 65.85 m in Hole 26CLAU115D including 1.99 m @ 17.40 g/t Au and 117 g/t Ag (1,613 g/t AgEq) including 0.63 m @ 37.40 g/t Au and 56 g/t Ag (3,274 g/t AgEq) 2.54 m @ 1.41 g/t Au and 866 g/t Ag (987 g/t AgEq) from 99.65 m in Hole 26CLAU112D including 0.41 m @ 5.63 g/t Au and 5,100 g/t Ag (5,584 g/t AgEq) 3.97 m @ 2.00 g/t Au and 112 g/t Ag (284 g/t AgEq) from 110.15 m in Hole 26CLAU118D including 1.38 m @ 4.72 g/t Au and 271 g/t Ag (677 g/t AgEq) including 0.51 m @ 9.19 g/t Au and 577 g/t Ag (1,367 g/t AgEq) "These results are extremely encouraging and mark an important step forward at the Claudia Project," stated Todd Anthony, President and CEO of Pacifica Silver.

"We have delineated a new high-grade mineralized shoot in the northern portion of the Aguilareña vein that contains the highest gold and silver grades ever drilled on the property, over significantly wider intervals than previously encountered --clearly demonstrating both the high-grade character and district-scale potential of the Aguilareña vein system.
