Glenstar to Conduct Comprehensive Geophysical Survey at Green Monster Project

Executive Summary

• Glenstar Minerals has engaged Hasbrouck Geophysics to conduct a Hybrid‑Source Audio‑Magnetotellurics (HSAMT) survey at the Green Monster Project in southwestern Nevada.
• The survey will be executed by a three‑person Advantage Geophysics field team, acquiring data every 50 m along 13 lines, with work slated to begin in early November 2025.
• CEO Dave Ryan says the HSAMT results will inform planning for Phase 2 drilling following the recent Phase 1 drill program that identified a polymetallic zone.

Key Details

• Contractor: Hasbrouck Geophysics, Inc. (Prescott, AZ) – responsible for survey design, supervision, processing, modeling, and final reporting.
• Field Team: Advantage Geophysics, Inc. (Phoenix, AZ) – three‑person crew to acquire data on site.
• Survey Design: Hybrid‑Source Audio‑Magnetotellurics (HSAMT).
• Data Acquisition Plan: 13 parallel lines; measurements taken at 50 m intervals.
• Processing & Deliverables: Conversion of raw data into 2‑D and 3‑D cross‑sections, depth/elevation formats, interpolated rectangular cube, horizontal depth slices, and a comprehensive technical report covering methodology, acquisition, processing, modeling, and interpretation.
• Start Date: Early November 2025 (field work commencement).
• Purpose: Provide detailed geophysical insight into the polymetallic zone discovered during May 2025 Phase 1 drilling to prioritize targets for Phase 2 drilling.
• Project Background: Green Monster Property comprises ~700 acres (35 federal lode claims) in Clark County, NV; recent sampling returned high‑grade Cu, Ni, Co, Zn, and notable Zn (>10%) and Ag (>200 ppm). No prior drilling before May 2025.

Notable Quotes

• Dave Ryan, President & CEO: “The HSAMT survey will provide key information and give us a much better understanding of the geophysical structure of the polymetallic zone discovered during the recent Phase 1 drill program, and will be an invaluable aid to us in planning the priorities for the Phase 2 drill program.”
