Infinitum drills 20.60 m of 1.91% Cu at La Adelita

INFINITUM COPPER REPORTS 20.60 METRES OF 1.91% COPPER, 2.00 G/T GOLD AND 40.91 G/T SILVER IN DRILLING AT LA ADELITA PROJECT

Infinitum Copper Corp. has released results from the first two of 12 diamond drill holes at Infinitum's flagship project, La Adelita in Sonora and Sinaloa states, Mexico. Drill hole AD-22-0018 returned 20.60 metres (m) of 1.91 per cent copper (Cu), two grams per tonne (g/t) gold (Au) and 40.91 g/t silver (Ag) starting at 163.15 m down hole in the Cerro Grande zone. This mineralization is hosted in pervasive skarn alteration with abundant magnetite coinciding with the highest-grade mineralization. Drill hole AD-22-0017 was drilled above AD-22-0018, on the same section, and encountered a 26.05 m long interval of strong skarn alteration with trace mineralization before it reached the target depth. The hole AD-22-0018 intersection is open in all directions along the favourable contact between limestone and the intrusive.

Magnetotelluric (MT) geophysical survey results for this area were received subsequent to drilling and interpretation indicates that mineralization may strengthen at depth below drill hole AD-22-0018.

Rafael Gallardo, senior exploration manager, states: "This phase of drilling was designed to extend the high-grade copper-gold-silver mineralized trends cut in historic drilling, which terminated against previously unrecognized folding and faulting of the host limestones. We are pleased that our team's improved geologic model has found strong mineralization across these apparent barriers and are very eager to see whether the magnetite and anomalies revealed by our MT geophysical survey add additional important layers to our targeting."

"Our drilling is off to a great start with these initial drill results confirming the high-grade mineralization at Cerro Grande and the geophysics indicating the system may strengthen to depth," states Steve Robertson, president and chief executive officer of Infinitum Copper. "La Adelita is clearly a very large system, and we are delighted to see such high grades across wide geographic areas. The more work we do, the more we like how our model for the overall mineralization model is developing."

Phase 1 diamond drilling program

Recognizing that La Adelita is a big system, Infinitum's exploration has followed a methodical approach, focusing on areas with the best opportunities to encounter continuous zones of high-grade mineralization. To date, Infinitum has focused on two of the five main target areas: A) the La Adelita anticline and B) the Las Trancas zone, where a 2022 discovery trench revealed 9.15 m of 16.45 grams per tonne gold, 1.90 per cent copper and 3.50 g/t silver.

Phase 1 drilling consisted of 12 holes totalling 2,574 metres focused on the high-grade copper-gold-silver skarn targets at Cerro Grande and the Cerro Grande footwall. Phase 2 drilling, expected to commence following the summer rainy season, will include targets at Las Trancas. This news release reports the first two of the 12 drill holes. The company will release additional drill hole results as they are available in the coming weeks.

Drill holes AD-22-0017 and 0018 were drilled 70 metres north of the old Adelita adit to seek the extension of the high-grade copper-gold-silver mineralization of the Cerro Grande zone and the recently discovered Cerro Grande footwall zone. The Cerro Grande footwall was identified as a fold repeat of the favourable host limestone through surface mapping completed by Infinitum's geological team earlier this year. Drill hole AD-22-0017 was the first attempt to test the target but was lost at a depth of 145.50 metres in massive skarn with trace mineralization. Drill hole AD-22-0018 was drilled at a steeper angle from the same pad as 0017 and successfully cut the entire zone.

Drill hole AD -22-0018

Drill hole AD-22-0018 intersected a zone 20.60 m wide of grossularite-andradite skarn with semi-massive magnetite and disseminated copper mineralization grading 1.91 per cent Cu, two g/t Au and 40.91 g/t Ag. This zone corresponds well with the surface-mapped Cerro Grande footwall zone and the intercept is open up dip, to depth, and to the north and south along the favourable contact between limestone and the intrusive. The mineralization consists of chalcopyrite, bornite and covellite, and the richest chalcopyrite, bornite and covellite zones correlate well with higher gold values. The magnetite content is estimated to vary from 15 per cent to 75 per cent over the 20.60 m length and iron values average 24 per cent. The semi-massive magnetite associated with the high-grade copper-gold-silver mineralization is expected to be detectable with detailed magnetometry, which should be a very positive factor for future exploration. A detailed magnetometer survey will be undertaken after vegetation dies back following the rainy season.

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 into every 20 samples in the case of standards, blanks and duplicates, and for rejects and pulps 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 village and then to ALS in Hermosillo City, by company personnel.

Mr. Robertson, president and CEO of the company, has acted as the qualified person as defined in national Instrument 43-101 for this disclosure and supervised the preparation of the technical information in this release.

About Infinitum Copper Corp.

Backed by a strong team of industry veterans, Infinitum Copper is advancing the La Adelita project, where the company has an option to earn an 80-per-cent interest. The high-grade copper-silver-gold La Adelita project is located in Sonora and Sinaloa states in Mexico and is subject to a 2-per-cent net smelter return. La Adelita is a carbonate replacement deposit located in a mineralized district with a rich history. Infinitum Copper also has an option to earn 100-per-cent interest in the Hot Breccia project in the heart of the Arizona copper belt about 90 kilometres north of Tucson, Ariz. The Hot Breccia project is prospective for porphyry copper and copper skarn mineralization.
