Vancouver, British Columbia--(Newsfile Corp. - April 15, 2024) - Sarah Armstrong-Montoya, President and Chief Executive Officer of Cordoba Minerals Corp. (TSXV: CDB) (OTCQB: CDBMF) (otherwise "Cordoba" or the "Company") is pleased to report on the diamond drilling activity at the Perseverance porphyry copper project, located in northwestern Arizona, USA.
The Perseverance porphyry copper project is under a Joint Venture and Earn-in Agreement with Bell Copper Corporation (TSXV: BCU) ("Bell Copper"). Cordoba has already earned a 51% interest and has the right to increase its interest to 80% of Perseverance by spending $14.2 million in exploration expenditures before April 24, 2026.
Prior drilling shows evidence of a nearby porphyry system
In January 2024, hole K-23 was drilled approximately 1,000 meters southeast of hole K-22 and 1,000 meters east-northeast of hole K-20 (Figure One). Both holes returned evidence to support the existence of a nearby porphyry system.
Hole K-22 tested a large low resistivity anomaly generated by a Magneto Telluric ("MT") survey that shares the characteristic features of the giant, high-grade Resolution porphyry copper deposit in Arizona owned by Rio Tinto. The hole encountered clay-filled breccia zones with minor occurrences of pyrite, chalcopyrite in quartz veins and stringers representing distal alteration and mineralization to a porphyry copper system. Hole K-20, intersected 321 meters of anomalous copper assaying 541 ppm copper, within a low MT resistivity anomaly that was interpreted as being on the outer margin of a porphyry copper deposit (refer to Cordoba news release dated October 19, 2021).
K-23 potentially points in the right direction to a porphyry system
Hole K-23 targeted an undrilled area that could potentially host the core of a porphyry system. The hole drilled through a thick series of gravel followed by a sequence of volcanic basalt that blankets the valley floor before being covered over by the recent gravel fill. Underlying the basalt, Laramide-age porphyry volcanic and tuffaceous units were intersected at 516 meters, which are intensely oxidized with hematite and limonite representing weathered pyrite and chalcopyrite that has formed as a gossan on the surface exposure of potential porphyry copper mineralization long before the basalt was extruded onto the land surface. Arizona copper deposits that produced approximately 10% of the world's copper were directly associated with Laramide intrusive rocks.
Hole K-23 continued in hematite, limonite impregnated and fracture-filled Laramide porphyry and tuffaceous rocks that were strongly sericite altered and acid leached to a depth of 571 meters. This style of alteration and leaching is commonly referred to as a "leached cap" situated at the top of a porphyry copper deposit. At 571 meters, the hole crossed through a major fault and breccia zone, and into weakly altered Laramide porphyry intrusive rocks with minor quartz veins with sphalerite, galena and tennantite to 579 meters. The hole ended at 590 meters in Laramide porphyry rocks with minor disseminated pyrite. Core interval between 516 meters and 590 meters in hole K-23 will be submitted for assay.
"We are glad to see hole K-23 returned with the appearance of true volcanic rocks in the Laramide porphyry system in a leached cap, which may indicate the top of a porphyry copper system at Perseverance," commented Ms. Sarah Armstrong-Montoya, President and CEO of Cordoba. "We intend to undertake a Typhoon™ IP-resistivity survey to better understand the system and target a follow-up drill campaign."
Next steps: TyphoonTM System to direct future drilling
A TyphoonTM IP-resistivity survey is intended to map out the east side of the project using one of Ivanhoe Electric's proprietary deep-penetration TyphoonTM high-power transmitter systems. Further exploration diamond drilling will be planned upon completion of this survey.
