VANCOUVER, BC - Infinitum Copper Corp. (TSXV:INFI)(OTCQB:INUMF) ('Infinitum' or the 'Company') is pleased to announce completion of the first phase of the current exploration program at its flagship La Adelita project in Sonora and Sinaloa States, Mexico. Exploration activities in 2022 have resulted in the discovery of three significant showings, including a previously announced trench at Las Trancas zone that returned 9.15 metres (m) of 16.45 grams per tonne (g/t) gold, 1.90% copper and 3.50 g/t silver (see Figure 1 and News Release April 13, 2022). The current geophysical interpretation has revealed several strongly anomalous results which will be the focus of the next phase of diamond drilling.

Highlights:

Interpretation of the Magneto Telluric (MT) geophysics study is complete, and the results show good correlation with historic drilling. The strongest anomalies are untested by drilling.

Twelve diamond drill holes were completed on the trend of high-grade copper-gold-silver skarn mineralization at the Cerro Grande zone, with a total of 2,574 metres, including 1,848 samples that have been sent to the lab for analysis with results pending.

New Land Access Agreement with Los Batequis Community will facilitate work such as road building and drilling in the Las Trancas zone

Rafael Gallardo, Infinitum's Senior Exploration Manager states, 'Sampling, drilling and mapping results reveal both vertical and lateral zoning in this large system. The overall zoning observed at La Adelita appears to be matched by geophysical anomalies and fits very well with the proprietary CRD model that guides our exploration. Now we have the geophysics to tie it all together and it has revealed some very compelling targets'

Drilling:

Twelve diamond drill holes, AD-22-0017 - 0028, were completed at the Cerro Grande zone, with a total of 2,574 metres of drilling, including 1,848 samples that have been sent to the lab for analysis (see Table 1 and Figure 2). The results of the drilling are pending. The Company has completed the initial phase of the 2022 diamond drill program at the Cerro Grande zone and is refining multiple targets slated for upcoming drilling. Heavy seasonal rains in August and September inhibit safe and productive drilling, so Infinitum expects to initiate Phase 2 drilling on permitted targets at Cerro Grande, Pericos and Las Trancas once conditions improve.

Phase one drilling tested pre-existing targets, confirming and extending the high-grade copper-gold-silver skarn mineralized trends, focusing on tracing mineralization through folds and across previously unrecognized post-mineral faults. The next phase of drilling will incorporate the results of phase one, including drill results, trenching and importantly, the geophysics interpretation which is discussed below.

This section shows a strong conductive anomaly related to the axial plane of the La Adelita Anticline. The strong anomaly is relatively close to the surface and is an attractive drill target that has never been tested by drilling.

In the area of line LC1N, the steeply dipping and north-south trending, post-mineral quartz-monzonite dyke increases in thickness and has an inflection towards the Northwest. This structural change indicates a favorable mineral deposition environment. Two holes have now been drilled on this section, including historic hole CG-10-004 which intersected two mineralized zones: 11.20 meters @ 1.10% Cu, 0.58 g/t Au and 40 g/t Ag and 5.32 meters @ 0.28% Cu, 0.1 g/t Au, 8 g/t Ag further down the hole. In 2022, hole AD-22-0028 was drilled looking for the extension to depth of the mineralization in hole CGDD-10-004 (see Figure 4). Results from AD-22-0028 are pending.

Drill holes are proposed from the west and east limb of the La Adelita Anticline. Surface mapping shows the La Adelita Anticline can be projected through much of the Cerro Grande zone area with Cerro Grande mineralization on the eastern limb of the anticline (See Figure 5). Surface mapping and prospecting indicates the prospective stratigraphy extends at least another 350 m north . To the south, the La Adelita Anticline can be traced for at least 1.2 kilometres where the receptive limestone horizon wraps around and is found all the way along the west flank of the anticline.

About Infinitum Copper

Backed by a strong team of industry veterans, Infinitum Copper is advancing La Adelita project, where the Company has an option to earn an 80% 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% NSR. La Adelita hosts a Carbonate Replacement Deposit located in a mineralized district with a rich history. Infinitum Copper also has an option to earn 100% interest in the Hot Breccia project in the heart of the Arizona Copper Belt about 90km north of Tucson, AZ. The Hot Breccia project is prospective for porphyry copper and copper skarn mineralization.
