Oroco Resource Corp. announces assay results from drill holes N032 through N038 (4,046 m of drilling) of its drilling program in the North Zone of its Santo Tomas property (the “Property”) located in northwestern Mexico. The Company 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 43 holes (28,119 m of drilling) have now been completed by the Company in the North Zone, spanning approximately 1,700 meters of strike length, with intersections of good-grade mineralization returned in all holes for which the Company has received assays. Drill holes N032 intersected good grade mineralization 300 m to the south of drill hole 20, the previous most southerly drill hole in the North Zone for which the Company has results, extending the strike of the North Zone to approximately 1,700 m. This sparsely drilled area of the deposit is prospective of greater width and depth than outlined in the historical modelling. Drill holes N033 and N034 were drilled down dip from hole N010 for the purpose of further delineating the central area of the North Zone.

Both drill holes returned significant intervals of higher-grade mineralization. Drill holes N035 and N036 continued the Company's efforts to confirm and expand the shallow-seated higher-grade mineralization along the central axis of the North Zone, with both holes returning significant intervals of higher-grade mineralization. N037 and N038, were each collared on the west side of the central spine of the deposit and continued to expand the mineralized zone to the west of the Gradeshell with intervals of good-grade mineralization.

N037, downdip of N021, N024, N002 and N006 and approximately 200 m west of the Gradeshell, shows that mineralization in this area is largely contained within the hanging wall. Notably, mineralization appears to be improving to depth. N038 intersected a zone of mineralization similar in nature to that of N037, with the best grade intervals being found in the hanging wall to the west of the Gradeshell.

Notably, N038 demonstrates that this area of the North Zone broadens to a very significant width lying within 75 m of the surface on the western flank of the Santo Tomas ridge. The Company has now completed 43 drill holes (28,119 m of drilling) in its 2021-2022 North Zone drilling confirming good grade mineralization along 1,700 m of strike, demonstrating a westward dipping panel with consistent grades down-dip to about 400-500 m depth below the ridge, bottoming about sea level. Importantly, the drill program has confirmed and expanded a zone of shallow-seated higher-grade mineralization extending down the central spine of the North Zone that is amenable to early year, low strip, open pit mining and delineated a mineralized hanging wall zone to the west of the Gradeshell that comes close to surface under the Santo Tomas ridge.

The program is nearing completion with the remainder of the program focussed on expanding the shallow seated mineralized zone on the hanging wall along the south-west side of the Gradeshell with the continued goal of increasing the resource in this newly identified zone. 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).
