Independent geochemical modeling identifies a Cu-Mo porphyry target at the Avispa project in Montero, Chile.Canadian Business Journal

TORONTO, September 27, 2022 (GLOBE NEWSWIRE) — Montero Mining and Exploration Ltd. (TSX-V: MON) (“Montero” or “Company) has received a positive report from Fathom Geophysics (“Fathom”) from its analysis of geochemical data on the Avispa property. The report, entitled 3D Footprint Modeling at Avispa, generated a 3D conceptual target showing potential locations of porphyry copper-molybdenum mineralization at depth.

Company geologists collected a pile of reverse circulation (RC) drill chips from a drilling site believed to have been completed on the Avispa site by BHP and Quantum Pacific Exploration Chile (“Quantum”) (Figure 1). Some samples returned anomalous copper (> 100 ppm Cu) and molybdenum (> 10 ppm Mo) values ​​as previously reported (PR138 08/23/2022) (Figure 2) . Avispa is located 40 km west of the Chuquicamata copper porphyry deposits, within a defined north-south trending Paleocene-Eocene Cu-Mo porphyry zone and is located between BHP’s Spence Cu-Mo mine and the KGHM/ Located 40 km north of Sierra Gorda Cu on South32. -Mo mine.

A drilling tip geochemical dataset from a region of closely spaced boreholes was analyzed by Fathom using proprietary software that compares it to an idealized model of the mineralized porphyry system. The results show significant matching targets modeled under the central portion of the processed region (Figure 3). Targeting success has led us to use fathom analysis in other areas of Avispa’s assets. RC borehole samples from the rest of the property and lithological samples from the San Salvador River Valley provide additional datasets for analysis by Fathom. Fathom’s analysis has been used to identify existing porphyry mineralization systems at depths such as those investigated by his Solgold in Ecuador (Solgold, 13 August 2020).

Montero President and Chief Executive Officer Dr. Tony Harwood commented: “Independent modeling performed using Fathom’s proprietary processing technology on geochemical samples taken from drill tip piles on the surface of the earth produced significant copper-molybdenum drill target areas at depth. , is being investigated for the potential to host important copper-molybdenum porphyry deposits near deep and other near-surface deposits.We continue to evaluate other areas of the property.”

The Fathom study was commissioned to leverage a uniquely crafted, model-driven approach targeting porphyry and associated mineralization. Fathom’s modeling results show significant and consistent 3D porphyry mineralization targets, as shown in Fig. 3.

We are evaluating other targets at Avispa along with Fathom to define potential porphyry drill targets. The results of this work are expected in Q4 2022 and will be integrated into the drill targeting program.
