Oroco Resource Corp. announced further assay results from the North Zone drilling program at its Santo Tomas project (the Property) located in northwestern Mexico. Holes N039 to N043 totalled 2,668 m of drilling which demonstrated continuity of good grade mineralization, including 135 m of 0.60 CuEq. The strike length of the North Zone now spans approximately 1,600 m. Drilling Results: All drill holes tested the deposit perpendicular to its structural attitude. Core intervals are within approximately 10% of true thickness.

Assay results and cross-sections through the first forty-three North Zone drill holes (21,379 m of drilling), the first seven Brasiles Zone drill holes (5,116 m) and the first three South Zone drill holes (2,054 m) are available at the Company's website. North Zone Deposit to the West Side of the Ridge: Drill holes N039 and N040 continued the Company's testing of the hanging wall side of the deposit in the north-west side of the central axis of the deposit. Drill hole N039 (Plate 59) returned three mineralized intervals, with a main interval of 265.0 m of 0.36% CuEq commencing approximately 40 m above the Gradeshell and extending 50 m below it.

Drill hole N040 (Plate 65) returned four mineralized intervals, with a main interval of 152.1 m of 0.33 CuEq in a downdip extension approximately 200 m to the west of the Gradeshell. Definingthe Southern Extent of the Central Axis of the North Zone: The southern portion of the North Zone is blind to surface and beneath a blanket of post-mineralization volcanic rock. Modelling of the historical results and structural analysis has successfully delineated the North Zone 400 m south from drill hole N020 to the limit of the zone at drill hole N043.

The North Zone program now has confirmed good-grade mineralization in a gently north-plunging panel beneath the Santo Tomas ridge, extending 1,600 meters along strike, to 400 m and 800 m downdip below surface. Drill hole N042 (Plate 44) returned 135.0 m of 0.60% CuEq extending across and below the Gradeshell. Drill hole N041 (Plate 40), collared approximately 200 m south of N042, continued the confirmation of the Gradeshell with two mineralized intervals, with the first interval returning 20 m of 0.35 CuEq, and the second main interval commencing 5 m deeper returning 96 m of 0.52 CuEq.

Drill hole N043 (Plate 38), collared approximately 100 m south of N041, returned three minor intervals of mineralization. N043 intersects the faults that are the south termination of the North Zone. Balance of the North Zone Program: The Company's has largely completed its North Zone drill program in support of the planned Preliminary Economic Feasibility Study.

The balance of the program focusses on horizontal drilling from the base of the Santo Tomas ridge. Horizontal holes and shallow dipping holes will allow testing of the southern 400 m of the North Zone, at depths 300 to 500 m below surface, to the south of hole N038 (plate 49). This area of the North Zone has the potential to add significant tonnage to the resource estimate being prepared in support of the planned Preliminary Economic Assessment.

South Zone Program: The Company's South Zone program has now drilled 19 holes (11,069 m) in its program to confirm and test the South Zone deposit, with the assay results of holes S004 through S019 pending. Historical drilling, surface geological mapping, and the Dias Geo 3D Induced Polarization survey have defined near-surface mineralization projected to 400 m below the surface along 2,500 m of strike length. Technical Information and Quality Control /Quality Assurance: The historical drilling data employed in this current exploration program was the subject of Data Verification procedures cited in the current Technical Report. Additional drill collar verifications were performed in the current program, and collar locations fit closely to the 2021/2022 survey control.

Appropriate QA/QC protocols governed geological logging, core sampling, sample preparation, analyses, and security during the current program, including quality controls with duplicates, standards, and blanks. Samples were submitted to the Mexican division of ALS Limited in Hermosillo, Mexico, for sample preparation to pulps. Sample pulps are then sent to ALS Canada Ltd. in Vancouver, Canada, for analysis. Total copper and molybdenum contents are determined by four-acid digestion with AAS finish. Gold was determined by fire assay of a 50-gram charge, or alternately, of a 30-gram charge (1 Assay ton).
