The Los Andes Project is a district-scale exploration area covering over 6,500 hectares (65 sq. km). Exploration by Caza has identified a number of high-sulfidation epithermal centers within the district as well as low-sulfidation epithermal veins along the periphery. Tertiary andesitic volcanic rocks associated with multiple intrusive rocks and caldera complexes host alteration and Au-Ag mineralization. The Company has identified several targets along a structural corridor over 11 km long. Au-Ag mineralization has been identified on surface associated with silicification, argillic alteration, breccia pipes, and diatremes.
Airborne Magnetic Survey
A high resolution helicopter-borne magnetic and radiometric survey covering some 55 square kilometers over the Los Andes area was completed April 18th, 2015 (figure 1). The survey was conducted by Geotech Ltd. (formerly Aeroquest Airborne) of Ontario, Canada. Approximately 550 line kilometers were flown at 100 meter line spacing with an average instrument height of 36 meters achieved.
Initial data processing was completed by Geotech – Aeroquest. Detailed final processing along with quality control was completed by Buks Lubbe, geophysicist of the Caza team. Results were modeled using Geosoft cloud-based Magnetization Vector Inversion software. Two 3-dimensional magnetic models were calculated: (1) a regional model with 50 meter cells over the entire area, and (2) a 25 meter 3D cell detailed model over the northern part of the survey.
