American Copper Development Corporation provided assay results from six diamond drill holes totaling 4,661m recently completed at the Lordsburg Project, New Mexico. 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. Based on results of the 2023 program, the company announced that it has significantly expanded its landposition to the east of the existing Lordsburg claims which now brings the new total land package to 1,205 contiguous Federal patented and unpatented lode mining claims, covering 9,462 hectares in area controlled by the Company.

AC23-001 This hole was designed to test the eastern extension of the historically mined North Atwood Vein, which was intersected between 335 ft and 498 ft. A second, previously unknown and un-named vein complex was cut between 907 ft and 962 feet. Mineralization consists of copper oxide and sulfides, pyrite +/- magnetite in strongly silicified and brecciated rock hosted by intensely and pervasively propylitized andesite.

AC23-002 AC23-002 was located approximately 3500 ft northeast of the Entrée Gold drilling and was designed to test a deep chargeability high along a potential structural corridor to the north and east of the pre-existing drilling. This hole did not contain significant copper assays; however, the hole did intersect intensely and pervasively k-spar altered and well mineralized pyrite-chalcopyrite-kspar stockwork veining most certainly indicative of porphyry style mineralization. Both Cretaceous andesitic wall rocks and Laramide porphyry and Laramide hydrothermal breccia contain extensive replacement of primary mineralogy and texture by chlorite, epidote and calcite with ubiquitous pyritic stockwork veining and disseminated chalcopyrite+/- magnetite.

While assays did not yield reportable widths and grades, spot analyses using a handheld Vanta XRF analyzer yielded up to 2600 ppm Cu. AC23-003 AC23-003 was collared north and west of the Anita Vein in an area with outcropping silicified breccia pipes and coincident radiometric K and magnetic anomalies, approximately 1 mile south of a strongly argillized roadcut. It was collared in unaltered, post-Laramide quartz monzonite porphyry and passed at shallow depth into Laramide feldspar porphyry affected by moderately pervasive propylitic alteration.

From 530 ft to 780 ft, strong phyllic alteration with quartz and sericite overprints the propylitized porphyry. This phyllic alteration zone, similar in appearance to the roadcut, hosts common and abundant, black calcite, Mn-oxide and sulfide bearing veinlets. The processes of leaching and secondary enrichment may be responsible for its occurrence.

AC23-004 AC23-004 was the longest hole of the program, reaching a final depth of 3826.5 feet. It was collared just east of the Misers Chest shaft and was designed to test the high-grade copper veins historically mined in addition to drilling beyond the deepest workings. This hole started in propylitized andesite, passing at 229 ft into propylitized Laramide porphyry.

At a depth of 830 ft, the drill hole cut into contact metamorphosed Cretaceous sediments of the Bisbee group. Hornfels, proto-skarn and silica-pyrite rock occur as alteration of the Bisbee group and persisted to the final drilled depth. Mineralized intervals within the contact metamorphosed units typically contain common, thin, irregular chalcopyrite veinlets with irregular, seemingly arbitrary, zones with chalcopyrite concentrations greater than 50% of the core volume.

AC23-005 AC23-005 was collared on the same pad as AC23-004, and was angled to the west to drill test a large maghigh anomaly surrounding the historic Misers Chest and Bonney workings. This hole also began in propylitized andesite before passing into propylitized Laramide porphyry at 257 ft and then into contact metamorphosed Bisbee Group sediments at 927 ft. As with AC23-004, hornfels, proto-skarn and so-called silica-pyrite rock of the Bisbee group persisted to the final drilled depth.

AC23-005 penetrated an open stope from the Miser?s Chest historic underground mine between 875 and 890 ft below collar. The stope and recovered core to a depth of 927 feet cut the Last Chance vein characterized by coarse grained masses of chalcopyrite and chalcopyrite veinlets with some 5 ft intervals displaying over 1% Cu assays. The hole was abandoned, prematurely, after penetrating a second underground working between 1304 ft and 1318 ft.

AC23-006 AC23-006 was also collared on the AC23-004 pad. It was drilled to the northeast and aimed to test the northeast projection of mineralization found in AC23-004. It was collared in propylitized Cretaceous Andesite and passed into propylitized Laramide porphyry at a depth of 151 ft.

Contact metamorphosed Bisbee Group sediments were first cut at a depth of 831 ft and persisted to 1038 feet. The next section of the hole passed back into Laramide porphyry, and then between 1555 ft and 1779 feet, Bisbee Group hornfels were again intersected. Bisbee Group hornfels and proto-skarn was observed down to where Laramide porphyry was cut from 1779 to the final drilled depth of 3000 ft.

The best mineralized interval, between 872 ft and 1017 ft was entirely within the contact metamorphosed Bisbee Group sediments and like the mineralization in AC23-004 contains common, thin, irregular chalcopyrite veinlets with irregular, seemingly arbitrary, zones with chalcopyrite concentrations greater than 50% of the core volume.
