Kobrea Commissions Property-Wide Airborne Magnetic & Radiometric Survey at Western Malargüe Copper Projects, Mendoza Province, Argentina

In This Article:

Vancouver, British Columbia--(Newsfile Corp. - March 13, 2025) - Kobrea Exploration Corp. (CSE: KBX) (FSE: F3I) (OTCQB: KBXFF) ("Kobrea" or the "Company") announces that it has commissioned a heli-borne magnetic and radiometric survey with New-Sense Geophysics Ltd. ("NSG") in conjunction with GeoEnergia Argentina S.A. ("GEA") to be completed at the Company's Western Malargüe Copper Projects. Kobrea holds the right to earn a 100% interest in the Western Malargüe Copper Projects, which consist of 7 projects totaling 733 km2 in southwestern Mendoza Province, Argentina (see the Company's August 19, 2024 news release for further details).

"The upcoming survey will be the first comprehensive geophysical survey covering these projects and will serve to better define known porphyry targets and outline additional porphyry targets within our land package," commented James Hedalen, CEO of Kobrea. "At El Perdido, this data will compliment historical geophysics which already indicates the potential for a large copper-bearing system coming to surface and extending to depth. At El Destino, we anticipate that the alteration footprint of the porphyry copper-gold target continues under younger volcanic cover to the north and south and this survey will help to ascertain the size potential of the porphyry system which already looks to be significant."

A property-wide, 2,245 line-kilometre magnetic-radiometric heli-borne geophysical survey has been planned which will provide insight to the scale, geometry and intensity of known alteration systems on the property along with potentially outlining additional porphyry targets within the project boundaries. The survey, scheduled to commence in the coming weeks, will include coverage of the El Perdido and El Destino porphyry copper targets.

The ground magnetometer survey completed by a previous operator at the El Perdido porphyry copper target covers the core of the system, while the airborne magnetometer data will present a more comprehensive picture of the geology and hydrothermal alteration beyond those limits defined historically. The radiometric data recorded will highlight the surficial distribution of potassic alteration and the extents of hydrothermally altered rock.

At El Destino, a 1-kilometre by 3-kilometre hydrothermal alteration system is suspected to continue under younger Pleistocene-aged ignimbrites to the north and south of the outcropping alteration footprint (Figure 1). The airborne magnetometer will measure the rock properties beneath the younger cover rock to define the greater extent of the hydrothermal alteration footprint. The radiometric data collected will serve to outline additional areas exhibiting potassic alteration beyond those mapped to date.
