Large Scale Porphyry System At The Lordsburg Project

VANCOUVER - American Copper Development Corporation reported on results from six diamond drill holes totaling 4,661m recently completed at the Lordsburg Project, New Mexico. The highlights include: 1) AC23-006 intersected 44m of 1.00% CuEq* (0.86% Cu, 10.55 g/t Ag, and 0.1 g/t Au) including, 18m of 2.13% CuEq, 14m of 2.75% CuEq, and 3.0m of 11.35% CuEq (9.48% Cu, 217.5 g/t Ag, and 0.56 g/t Au). 2) AC23-005 intersected 9.9m of 0.52% CuEq (0.44% Cu, 9.57 g/t Ag, and 0.2 g/t Au). 3) AC23-004 intersected 38m of 0.39% CuEq including, 12m of 1.02% Cu Eq (0.94% Cu, 9.44 g/t Ag, and 0.2 g/t Au). 4) AC23-001 intersected 36.6m of 0.38% CuEq including, 7.6m of 0.69% CuEq (0.52% Cu, 18.90 g/t Ag, and 0.06 g/t Au).

The 2023 drilling campaign was designed to follow up on and extend previously identified porphyry copper related mineralization, test previously undrilled areas in and around the known high-grade copper, silver, gold vein mineralization at the historic Bonney and Misers Chest mines, and test newly identified areas for porphyry copper mineralization based on the 3D DCIP/MT Titan survey completed by Quantec earlier this year.

Rick Van Nieuwenhuyse, Chairman, said, “Results from our initial exploration program have demonstrated that a very large-scale porphyry system is active at Lordsburg with widespread high-grade intervals of copper mineralization. We are very pleased with these initial results from the Phase I drill program. They demonstrate widespread pervasive propylitic and phyllic alteration with copper mineralization consistently associated with chalcopyrite-magnetite-kspar stockwork veining. Hole AC23-006 intersected a solid interval averaging 1% copper equivalent with multiple higher grade zones. Hole AC23-005 intersected unmapped underground workings, which resulted in having to abandon the hole. This hole was intended to test a large Mag-high signature further west and remains untested. The strong association of chalcopyrite and magnetite suggest vectoring on Mag highs needs to be further drill tested. We were also able to re-log the drill core previously drilled by Entrée Gold. All of this information is being integrated into our 3D drill hole database along with the geophysical and multi-element geochemical data and will be used to vector into the core of the system. The large-scale footprint is demonstrated, and now we need to use science and hard work to find the porphyry copper center."
