FINAL DRILLING RESULTS FROM 2022 CAMPAIGN CONTINUE TO DEMONSTRATE THE HIGH-GRADE POTENTIAL OF LA ADELITA INCLUDING 48.7M OF 1.22% CUEQ

Infinitum Copper Corp. has released results from the last six of 12 diamond drill holes at Infinitum's flagship project, La Adelita in Sonora, Mexico.

Drill hole AD-22-0028 returned 48.7 metres (true width) of 1.22 per cent copper equivalent, starting at 198.85 m down hole in the Cerro Grande zone, while AD-22-0021 returned 19.85 m of 1 per cent CuEq from 34.5 m down hole. Similar to previously released drilling results, mineralization is hosted in pervasive skarn alteration and highly correlated with magnetite. AD-22-0028 was collared 65 m to the north of AD-22-0018, which returned 20.6 m of 3.71 per cent CuEq from 163.15 m down hole, and 175 m to the north of AD-22-0019, which returned 32.25 m of 1.74 per cent CuEq from 36.65 m down hole. The intersection of hole AD-22-0028 is open to the north, east and west.

AD-22-0028 is the only drill hole that has intersected the large and distinct magnetotelluric anomaly on the eastern flank of the Cerro Grande anticline. It is believed that the anomaly is driven by highly conductive magnetite that is strongly correlated with high-grade gold and copper mineralization. The anomaly stretches 1.4 kilometres from north to south and is open to the north, with a diameter of 200 m at its thickest points.

Rafael Gallardo, senior exploration manager, stated: "Hole 28 is particularly exciting because it demonstrates that the mineralization is open to the north, which is also supported by our geophysical studies, and our recent surface mapping demonstrates the continuity of contact between intrusive rocks and favourable calcareous host rocks at least 350 metres to the north of the drill hole AD-22-0028."

Drill hole AD-22-0027 was drilled farther to the south-southwest of drill hole AD-22-0021, looking for the continuity of the system. This hole was drilled with a low-angle inclination (minus-45 degrees) and intercepted a wide, strong zone of skarn alteration, without magnetite, including 130.9 m of 0.32 per cent zinc from 141.20 m down hole.

"Two thousand twenty-two's exploration program certainly exceeded expectations, with half of the holes drilled returning high-grade intercepts over meaningful widths. The evidence of the strong correlation between magnetite and mineralization continues to build, and as it does the number of targets continues to grow," said Matt Hudson, chief executive officer of Infinitum Copper. "All of this is happening at Cerro Grande, which represents about 5 per cent of the project area. We also look forward to exploring the Sangre del Toro area, where trenching returned nine m of 16.45 grams per tonne gold and 1.9 per cent copper, located 4.4 km southwest of Cerro Grande. We've got plenty of work to do in 2023."

Quality assurance/quality control

Diamond drill core sampling from the 2022 program was supervised by Infinitum Copper personnel. The split core samples were delivered to the internationally certified ALS Minerals laboratory facilities in Hermosillo City, where the samples were prepared by creating a pulp, and then shipped to Vancouver, Canada, for analysis. Assaying was done by ALS in Canada under an ISO 1702 quality management system. Samples were fire assayed for Au (Au-AA24) and analyzed for multielements using method code ME-ICP61, following an aqua regia digestion. Overlimits were analyzed using the most-appropriate method. Multielement geochemical standards, blanks and duplicates are inserted systematically into the rock sampling series to monitor lab performance. The control samples are inserted every 20 samples in the case of standards, blanks and duplicates, and for rejects and pulp duplicates, each 30 samples intercalated. Chain-of-custody controls track the samples, which are transported from the La Adelita project to the camp in Picachos and then to ALS in Hermosillo City by company personnel.
