Final Drilling Results From 2022 Campaign Continue to
Demonstrate the High-Grade Potential Of La Adelita Including
48.7m of 1.22% CuEq
VANCOUVER, BC / ACCESSWIRE / May 2, 2023 / Infinitum Copper Corp.
(TSXV:INFI)(OTCQB:INUMF) ("Infinitum" or the "Company") is pleased to report results from
the last six of twelve diamond drill holes at Infinitum's flagship project, La Adelita in Sonora,
Mexico.
Drill hole AD-22-0028 returned 48.7m (True Width) of 1.22% CuEq starting at 198.85 m
down hole in the Cerro Grande zone (see figures 1, 2 and 3) while AD-22-0021 returned
19.85m of 1.00% CuEq from 34.5 m down hole. Similar to previously announced drilling
results, mineralization is hosted in pervasive skarn alteration and highly correlated with
magnetite. AD-22-0028 was collared 65m to the north of AD-22-0018 which returned 20.6m
of 3.71% CuEq from 163.15m down hole and 175m to the north of AD-22-0019 which
returned 32.25m of 1.74% CuEq from 36.65m 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 which has intersected the large and distinct magneto-telluric
anomaly on theeasternflank of the Cerro Grande anticline. It is believed that the anomaly is
driven by highly conductive magnetite which is strongly correlated with high grade gold and
copper mineralisation. The anomaly stretches 1.4km from north to south and is open to the north
with a diameter of 200m at its thickest points.
Rafael Gallardo, Senior Exploration Manager, states "Hole 28 is particularly exciting because it
demonstrates that the mineralisation 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 meters to the north of
the drill hole AD-22-0028"
Drill hole AD-22-0027 was drilled further 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 (-45°)
and intercepted a wide strong zone of skarn alteration, without magnetite, including 130.90 m of
0.32% Zn from 141.20 m down hole.
"2022'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 mineralisation continues to build and as it does the number of targets
continues to grow" said Matt Hudson, CEO of Infinitum Copper. "All of this is happening at
Cerro Grande which represents about 5% of the project area. We also look forward to exploring
the Sangre del Toro area where trenching returned 9m of 16.45g/t Au and 1.9% Cu located 4.4
km southwest of Cerro Grande. We've got plenty of work to do in 2023".

Table 1: Final drill results from 2022 campaign.
Assumptions used in USD for the copper equivalent calculation were metal prices of $3.25/lb.
Copper, $1,600/oz Gold, $20/oz Silver, and recovery is assumed to be 100% as no metallurgical
test work has been completed on this project. The following equation was used to calculate
copper equivalence: CuEq = Copper (%) + (Gold (g/t) x 0.7182) + (Silver (g/t) x 0.0090).

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 multi-elements using method code ME- ICP61, following an aqua regia digestion.
Over limits were analyzed using the most appropriate method. Multi-element 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 La Adelita
project to the camp in Picachos village and then to ALS in Hermosillo City, by Company
personnel.
