[{"type":"text","content":"Cordoba Minerals Announces Diamond Drilling Results at Its 100%-Owned San Matias Copper-Gold-Silver Project in ColombiaVancouver, British Columbia--(Newsfile Corp. - May 27, 2022) - Sarah Armstrong-Montoya, President and Chief Executive Officer of Cordoba Minerals Corp. (TSXV: CDB) (OTCQB: CDBMF) otherwise \"Cordoba\" or the \"Company\"), provides an update on the recently completed exploration diamond drilling at the 100%-owned San Matias Project.Highlights: Cordoba completed a total of 2,152.7 metres (m) of diamond drilling within four holes focused on the suspected buried Alacran Porphyry Target (below the proposed open pit) and two holes within the Alacran Northern Extension Target. Mineralization within drill holes ACD094, ACD096 and ACD096A within the Alacran proposed open pit was consistent with the mineral resource block model (Figure 1 and Table 1). ACD094 - intersected 1.11% copper (Cu) and 0.19 g/t gold (Au) and 12.35 g/t silver (Ag) over 27.35 m (1.21% copper equivalent (\"CuEq\")). These drill holes did confirm the continuation and down dip edge of the Alacran mineralization, which provided additional support for the mineral resource; however, the deeper source of the porphyry clasts seen in the previous drilling could not be located (refer to drill holes ACD084A, ACD094, ACD096 and ACD096A in Figure 1).The Alacran Northern Extension Target, drill holes ACD093A and ACD095, in Figure 1, continued to intersect the barren unit 2, sterilizing this northern area of possible mineralization. The origin of the Northern Extension Target's geochemical anomaly remains unexplained.The mineralized porphyry clasts seen so far are \"xenoliths\" located in restricted portions of a late mineral dacite intrusion (dacite breccia) which has at least some evidence for phreatomagmatic activity. Since these breccias can source material some distance from where they are emplaced, they do not give clear support for the porphyry source to be immediately adjacent or below the Alacran deposit. Nor has any hydrothermal alteration suggesting a vector towards a nearby porphyry source (laterally or at depth) been seen in the host stratigraphy. Therefore, the search for the source porphyry will move outward of the Alacran deposit and will require further mapping and geophysical surveys to provide new targets.\"We have received encouraging assay res...
