Oroco Resource Corp. announced assay results from an additional 3,594 m of drilling from Holes N019 through N026 of its drilling program in the North Zone of its Santo Tomas property located in northwestern Mexico. The current drill program is continuing to confirm and expand the 2009 Gradeshell model of Cu >0.30% (the “Gradeshell”) derived from the historical drilling described in the Company's 2019 Technical Report.

A total of 35 holes (22,769 meters of drilling) have now been completed in the North Zone, spanning approximately 1,300 meters of strike length, with intersections of good grade mineralization returned in all holes for which the Company has received assays. DRILLING RESULTS: All drill holes tested the North Zone deposit perpendicular to its structural attitude. Core intervals are within approximately 10% of true thickness.

Assay results and cross-sections through the first twenty-six North Zone drill holes (18,136 m of drilling) are available at the Company's website. Extension of the Deposit to the West The Company's new strategy of drilling angle holes from the hangingwall of the deposit has reliably intersected a previously untested western shoulder to the main body of North Zone mineralization that is blind to the surface. Drill hole N019 (Plate 63) returned 2 significant intervals, both outside the Gradeshell: 127.8 m of 0.29% Copper Equivalent above the Gradeshell, and 126.0 m of 0.25% CuEq lying downdip.

Drill hole N021 (Plate 61) returned four mineralized intervals, all outside the Gradeshell, with two main intersections of 81.4 m of 0.40% CuEq and 32.9 m of 0.49% CuEq lying above the Gradeshell. Drill hole N024 (Plate 61) returned several intervals above, within and below the Gradeshell, with two main intervals: 86.6 m of 0.37% CuEq within the Gradeshell, and 90.1 m of 0.26% CuEq below the Gradeshell. DefiningShallow, Higher-grade Mineralization Along the Central Axis of the North Zone Drill holes N022, N023, N025 and N026 targeted shallow-seated mineralization in the eastern section of the North Zone with the goal of confirming the historical results which were generally of a higher-grade.

The current drill holes not only confirmed the mineralization in this area, but also returned intervals of mineralized material that are generally higher grade than the comparable historical results. Drill hole N022 (Plate 63) returned 152.1 m of 0.45 CuEq starting at 33m from surface, and 102 m of 0.24% CuEq starting in the Gradeshell and extending below it. Mineralization is shown to exist across the entire thickness of the Gradeshell and extends above and below it.

Drill hole N023 (Plate 62) returned 139 m of 0.35% CuEq, including 56.7 m of 0.61% CuEq starting at 4 m from surface. Drill hole N025 (Plate 59) returned an interval, starting from surface and extending below the Gradeshell, of 286.0 m of 0.45% CuEq. This intersection is one of the most significant in the current drilling program.

Drill hole N026 (Plate 65) returned two main intervals: 92.2 m of 0.68% CuEq starting from surface, and 69.8 m of 0.29% CuEq, both within the Gradeshell. Extension Along Strike to the South Historical drilling delineated approximately 1,600 m of strike length to the North Zone. The southern 500 m of that length is blind to the surface, sparsely drilled, and open to discovering mineralization at depth and on the shoulders of the main deposit.

Drill hole N020 is currently the southernmost of the North Zone drill program, lying approximately 240 m south of Holes N015 and N017, and extending the strike length of the North Zone drilled by the Company to about 1,300 m. The hole returned 151.6 m of 0.49% Copper Equivalent (CuEq), much of which lies outside the Gradeshell. Drilling is currently planned for areas north, south and down dip (to the west) from Hole N020. NORTH ZONE PROGRAM The North Zone drilling program is designed to confirm and expand the 2009 Gradeshell model, delineate near-surface mineralization amenable to open-pit mining methods, and reduce waste rock stripping ratios.

To date, the program has confirmed good grade mineralization in a gently north-plunging panel along the Santo Tomas ridge, extending 1,300 meters along strike at surface. The panel dips to the west and comprises consistent grades down-dip to about 400-500 m depth below the ridge, bottoming at about sea level. The Company's focus in the North Zone for the rest of 2022 is threefold: (1) to continue expanding the mineralized zone on the hanging wall to the west of the Gradeshell along the length of the deposit to potentially increase the resource and reduce the amount of waste rock stripping required; (2) to continue targeting the shallow seated mineralization in the eastern section of the North Zone to continue to confirm the higher grade shallow seated mineralization along the length of the deposit; and (3) to drill the relatively untested 600 m to the south of holes N015 and N017 along which the North Zone is shown to extend.

This area of the North Zone is prospectively of greater width and depth than the historical modeling and the Company intends to drill it with regular spacings to potentially establish a mineral resource in this area. SOUTH ZONE PROGRAM The Company has mobilized two drills to confirm and expand the South Zone deposit. 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.

Drill holes S001 (735.5m), S002 (617.1 m) and S003 (701.5 m) are complete, and drill hole S004 is presently in progress.
