Vancouver, British Columbia--(Newsfile Corp. - June 25, 2026) - Glenstar Minerals Inc. (CSE: GSTR) (OTCQB: GSTRF) (FSE: VO20) ("Glenstar" or the "Company") announces that it will be conducting a Terēan survey at its geologically complex Green Monster Project in Clark County, Nevada, in order to gain a more detailed understanding of the intricate and complicated geological structures present on the property.
The Survey will begin on Monday, June 29, 2026 and will consist of four (4) shear-wave velocity structure cross sections collected along 2,400 ft long arrays. This survey is designed to image cover thickness, depth to bedrock, key structural and lithologic features (faults and voids), and will extend from the surface to a 600 ft cross section depth. The final interpretation will be tied to the currently available subsurface data and analysed for inclusion in the final report.
This type of survey is very cost effective and highly successful in mapping faults and structural controls on mineralization, defining depth to competent rock, quantifying overburden, imaging paleochannels & alteration zones, and identifying weathered and fractured zones that could indicate the presence of large faults and their orientation.
Glenstar Geologist Bob Marvin noted that, "The results of the Phase 2 drill program provided us with some solid data regarding mineralization. However, the results also showed that there is a definite complexity to the geologic structure, or structures, underlying the project. The Terēan survey should provide more advanced, detailed information that will help determine what the next phase of drilling and exploration should look like going forward."
Numerous polymetallic zones were encountered during the Phase 2 program, which consisted of six (6) holes drilled to depths from 500 feet to 585 feet encompassing ~3,320 feet of total drilling across three (3) drill pads. These holes contained highly fractured rock with abundant clay alteration and brightly coloured orange and red oxide minerals and decalcification. Assay results confirmed that the area of interest is significantly mineralized and geologically complex; however, at this early stage of exploration the grades reported are less than expected while at the same time raising a number of interesting questions. As a result of this geological complexity, further geophysical work is required to address the data that is inconclusive and provide a clearer understanding of the type of structure and system contained within the property.
