2,300-Metre Program to Test the Alacran Porphyry and Alacran Northern Extension Targets

Vancouver, British Columbia--(Newsfile Corp. - November 29, 2021) - Sarah Armstrong-Montoya, President and Chief Executive Officer of Cordoba Minerals Corp. (TSXV: CDB) (OTCQB: CDBMF) otherwise "Cordoba" or the "Company") is pleased to announce the commencement of a 2,300-metre exploration diamond drilling program at the 100%-owned San Matias Project.

Highlights:

  • Two high-priority exploration targets: the Alacran Porphyry Target and the Alacran Northern Extension Target, will be tested with an initial 2,300-metre diamond drill program - commencing immediately. Based on results, the drill program may be increased to 3,000 metres.

  • Cordoba has identified one late-mineral intrusive breccia phase at Alacran which truncates and reworks the Deposit (refer to Cordoba's news release dated October 30, 2018). Notably, the dacitic breccia phase contains clasts of porphyry-style mineralization with potassic alteration - a potential indication of an underlying porphyry source. Cordoba will test the Alacran Porphyry Target with two drill holes (refer to collars ACD084 and ACD087 in Figure 1).

  • The Alacran Northern Extension Target is defined by extensive soil and stream sediment geochemical anomalies, specifically elevated levels of copper, gold, silver, molybdenum, zinc, tungsten and indium, which are key pathfinder metals in the district. Three drill holes are planned to test this target (refer to collars AEXP001, AEXP002 and AEXP003 in Figure 1).

"We are encouraged by the results from the extensive fieldwork program of the San Matias Project," commented Ms. Armstrong-Montoya, President and CEO of Cordoba. " The drill program will uncover the geological potential of the underlying porphyry source and northern extension of the Alacran Deposit."

2021 Drill Program

Based on the results from the extensive fieldwork program completed in 2018, Cordoba has prioritized two exploration targets at San Matias that will be tested with an initial 2,300-metre diamond drill program. The 5-hole exploration diamond drilling has already commenced with two diamond drill rigs testing both the Alacran Porphyry and Alacran Northern Extension targets.

Alacran Porphyry Target

Diamond drilling will target the potential underlying porphyry source of the Alacran replacement copper-gold Deposit. Drill hole ACD084 was halted at a depth of approximately 127 metres in the previous exploration campaign, and will now be extended to a depth of approximately 700 metres. The second hole ACD087, will be approximately 240 metres southwest to the first hole, and will be drilled to a depth of approximately 700 metres. The porphyry target was recognised through observation of porphyry clasts within the dacitic breccia that suggest a deeper source being scavenged. The dacitic breccia has been observed cutting the same structures that earlier introduced the Alacran mineralizing fluids (refer to Figures 2 and 3). A conglomerate within Unit 2 of the Alacran stratigraphy contains similar porphyry clasts, indicating that one proximal porphyry phase pre-dates Alacran stratigraphy (refer to Figure 4).
