Vancouver, British Columbia--(Newsfile Corp. - January 11, 2024) - Sonoran Desert Copper Corporation (TSXV: SDCU) ("SDCU'' or the "Company") is pleased to announce the results from the comprehensive sampling program on the Company's Cuatro Hermanos Porphyry Copper Project (the "4H Project").
The 4H Project is located in Sonora, Mexico, and comprises 10 concessions totalling 8,125 hectares and contains a large porphyry copper-molybdenum system with surface measurements of at least four kilometres east-west by two kilometres north-south. The Company released a recent NI 43-101 report on the 4H Project in October 2023 which comprised a review of historical work. Historical resources were last estimated in 2008:

Primary sulphide mineralisation is chalcopyrite and molybdenite with secondary oxide chalcocite.
CEO Brian Leeners stated, "We are thrilled to announce these exceptional results from our sampling program across various areas of the 4H Project in Sonora, Mexico. In particular, the copper grades in the South Conglomerates greatly exceeded our expectations, underscoring our view that the soluble copper content in the North and South Conglomerates, in addition to the supergene zones at the 4H Project have the combined potential for a significant Heap Leach & SX-EW operation. These outstanding results combined with the enormous size and potential of the 4H Copper Moly Porphyry, affirm our position as a rising player in the junior copper sector. We look forward to leveraging this positive momentum as we continue to advance and develop the 4H Project in Sonora."
Sampling Program
Under the sampling program, 82 rock samples were collected with a focus on the areas of the 4H Project that have received minimal historical attention.
New Zones
Noemi Zone - 10 samples collected
| NOEMI | Cu (ppm) | Mo (ppm) | Ag (ppm) | Au (ppm) |
| Min | 37.7 | 2.57 | 1.14 | 0.02 |
| Max | 1915 | 67 | 173 | 5.21 |
| Average | 336.5 | 18.0 | 45.5 | 1.0 |
| Std Deviation | 572.9 | 18.1 | 61.7 | 1.6 |
10 samples were collected from the Noemi Zone. Noemi is a higher-level PCD apophyses and returned elevated precious metals values. No drill results exist for this target, however there is road access to the test pits on the peaks. Noemi Zone is interpreted to be peripheral to the primary Cu-Mo Zone of the porphyry complex due to the elevated Ag, Au, Pb, and Zn.
South Conglomerate Zone - 20 samples collected
| SOUTH CONGLOMERATE | Cu (ppm) | Mo (ppm) | Ag (ppm) |
| Min | 102 | 1.68 | 0.21 |
| Max | 162,500 | 49.8 | 1.54 |
| Average | 17,363 | 22.1 | 0.9 |
| Std Deviation | 35,184 | 13.9 | 0.3 |
The combined surface areas of the known conglomerates (North and South) at 4H is 1.7 million square metres (170 hectares). The recent sampling program focused on the South Conglomerate area and those 20 samples provided an average Cu grade of

The South Conglomerate area is relatively higher grade. The immediate development plan is to conduct percussion drilling in this area. It is anticipated that this drilling program, along with permitting, metallurgy and acid-sourcing will all be completed in 2024.
The soluble copper content in the North and South Conglomerates, in addition to the supergene zones at 4H are interpreted to have the combined potential for a significant Heap Leach & SX-EW operation.
Historic Zones
Main Zone - 6 samples collected within the historic resource area
| MAIN | Cu (ppm) | Mo (ppm) | Ag (ppm) |
| Min | 93.1 | 4.13 | 0.05 |
| Max | 274 | 215 | 6.45 |
| Average | 196.6 | 100.1 | 1.7 |
| Std Deviation | 60.1 | 89.9 | 2.6 |
This magmatic breccia is comprised of at least 5 fertile porphyritic intrusives of intermediate composition with a fertile granodioritic matrix. Multi-generational porphyry mineralization is inferred from intrusive clasts displaying A + B-type veins which are later cut by A + B-type veins cutting both matrix and clasts.
West Zone - 6 samples collected
| WEST | Cu (ppm) | Mo (ppm) | Ag (ppm) |
| Min | 37.8 | 17.25 | 0.23 |
| Max | 2750 | 391 | 3.61 |
| Average | 1204.8 | 131.3 | 1.44 |
| Std Deviation | 977.6 | 141.2 | 1.2 |
The 2008 core drilling proved the West Zone to be a significant future development target within the 4H Project. Basin and range tectonics have affected the entire region and several large post-mineral faults have displaced portions of the porphyry body, but the primary zone is largely intact. Initial data compilation and 3D modelling indicate a good probability to connect the Main and West Zones.
Cactus Zone - 3 samples collected
| CACTUS | Cu (ppm) | Mo (ppm) | Ag (ppm) |
| Min | 1,840 | 132 | 8.17 |
| Max | 67,900 | 336 | 13.95 |
| Average | 35,980 | 217.5 | 10.6 |
| Std Deviation | 33,086 | 105.9 | 3.0 |
The Cactus Zone is an upper level structural porphyry copper target immediately NE of the Main Zone. The high moly content may indicate that this is another mineralized apophyses to test at depth.
San Lorenzo Zone - 37 samples collected
| SAN LORENZO | Cu (ppm) | Mo (ppm) | Ag (ppm) |
| Min | 4 | 0.14 | 0.01 |
| Max | 22,500 | 96.70 | 60.00 |
| Average | 705 | 8.22 | 2.46 |
| Std Deviation | 3,688 | 17.73 | 9.99 |
This is a large concession that needs to be evaluated further. There is a large intrusion exposed along a major SW-NE structure that follows the southeastern boundary of the concession.
