Infinitum Copper Corp. announced results from the first two of twelve 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% copper (Cu), 2.00 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 (see figures 1, 2 and 3). This mineralization is hosted in pervasive skarn alteration with abundant magnetite coinciding with the highest-grade mineralization (See Table 1). 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 favorable contact between limestone and the intrusive.
Magneto-telluric (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 & CEO 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 (Figure 1): 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 (g/t) gold, 1.90% copper and 3.50 g/t silver.
Phase 1 drilling consisted of 12 holes totaling 2,574 metres focused on the high-grade copper-gold-silver
skarn targets at Cerro Grande and the Cerro Grande Footwall (see Figure 1). 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 twelve 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 meters 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. Cerro Grande Footwall was identified as a fold repeat of the favorable 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 intersected a zone 20.60 m wide of grossularite-andradite skarn with semi-massive
magnetite and disseminated copper mineralization grading 1.91% Cu, 2.00 g/t Au and 40.91 g/t Ag (Table
1). This zone corresponds well with the surface mapped Cerro Grande Footwall zone (see Figures 2 and 3)
and the intercept is open up-dip, to depth, and to the north and south along the favorable 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% to 75% over the 20.60 m length and iron values average
24%. 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.
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 is 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.
