Newly Discovered Polymetallic Zone at Green Monster Project Shifts Focus of Drilling and Exploration Plan
Glenstar Minerals (OTCQB: GSTRF) has announced significant findings at its Green Monster Project in Nevada, following its May 2025 drill program. A new polymetallic zone was discovered in hole GMST-4, located 150 metres away from the main target zone. The newly found mineralization, approximately 10 metres wide, contains exceptional mineral grades including >30% zinc, 177 ppm silver, 523 ppm nickel, 91.9 ppm cobalt, and >0.36% copper.
The discovery was made at depths between 131-142 metres in the hanging wall of the Green Monster Fault Zone. This finding has prompted Glenstar to shift its exploration focus, with Phase 2 drilling now planned to expand the new zone. The Green Monster Property, comprising 35 federal lode claims covering ~700 acres, is part of a larger 30-kilometer fault zone known for zinc mineralization with anomalous nickel, cobalt, and copper occurrences.

Nel foro GMST-4 è stata individuata una nuova zona polimetallica, distante 150 metri dal target principale. La mineralizzazione rilevata, di circa 10 metri, presenta tenori eccezionali: >30% zinco, 177 ppm argento, 523 ppm nichel, 91,9 ppm cobalto e >0,36% rame.
La scoperta è avvenuta a profondità comprese tra 131 e 142 metri nel hanging wall della Green Monster Fault Zone. Questo risultato ha spinto Glenstar a riprogrammare le attività esplorative: è ora prevista una Fase 2 di perforazione per estendere la nuova area. La proprietà Green Monster, costituita da 35 concessioni minerarie federali (lode claims) per circa 700 acri, fa parte di una fascia di faglia lunga 30 km nota per mineralizzazioni di zinco con anomalie di nichel, cobalto e rame.

Vancouver, British Columbia--(Newsfile Corp. - August 13, 2025) - Glenstar Minerals Inc. (CSE: GSTR) (OTCQB: GSTRF) (FSE: VO20) ("Glenstar" or the "Company") is pleased to provide an update on the Green Monster Project in southwestern Nevada, following positive results from the drill program undertaken in May 2025 (see news release dated July 16, 2025).
The ongoing review of the data obtained from this most recent drill program, along with data compiled from previous exploration field work, has raised a number of interesting questions that will hopefully be answered in the phase 2 drill and exploration plan currently being finalized.
The intersection of a zone of robust polymetallic mineralization in a position 150 metres away from the main target zone of the phase 1 drill program has resulted in a change in the focus for exploration of the property, and Glenstar is now planning for extension drilling of the new zone. Hole GMST-4 was meant to test a magnetic high that was previously identified during the Company's exploration field work of the property in 2023. This new zone is approximately 10 metres (32 feet) wide and is centered on a very high-grade zinc occurrence that is >
While hole GMST-4 was simply intended to test a magnetic high, the drill placement and drilling conditions resulted in the hole barely grazing the southeast edge of the magnetic subsurface feature. This led to the discovery of unexpected strong mineralization in a significantly different stratigraphic unit that was not part of the main area of interest for the Phase 1 drill program. It is important to note that the newly discovered zone in no way explains the magnetic anomaly, as the intersection is strongly oxidized and has no magnetic response. The magnetic high has yet to be explained and could result from sulfide mineralization at deeper levels.
The mineralization was intersected within a complex rock unit containing limestone, sandstone, and shale, which is known to be disrupted by numerous thrust faults, and the mineralization is contained within a strongly decalcified section of the host rocks. A general analog from the current data we have is the Eureka District in central Nevada where gold, silver, zinc, and lead were produced from strongly oxidized and faulted carbonate stratigraphy.
According to Glenstar's project geologist Bob Marvin, "The extraordinary results that came back for hole GMST-4 have significantly altered our next stage exploration and drilling plans for the property, and Phase 2 will focus on expanding the new hanging wall zone and testing the continuation along strike and at depth."
This new zone is completely open and represents a significant increase to the target size of the project.
Glenstar's Green Monster Property ties into the larger district scale Green Monster Fault Zone, which is approximately 30 kilometres (18.6 miles) in length and well known for containing a preponderance of zinc, but has also shown a number of areas that are significantly anomalous for nickel, cobalt and copper. Results from previous field work indicated that the Green Monster Property is one of those prospective areas, and the assay results, thus far, from this initial drill program appear to support the preliminary findings from earlier exploration activities.
Project Background & Recent Exploration Work
The Green Monster Property is comprised of 35 federal lode claims covering ~700 acres located in Clark County, Nevada, on the west trending spur of the Spring Mountains and is approximately 40 miles southwest of Las Vegas. Until the recent drill program in May of 2025, no drilling was ever conducted on the property, but the Company's previous identification of robust nickel-copper with highly anomalous cobalt from sampling work done in 2022 indicated that several targets were ideal for shallow RC drilling.
Glenstar acquired the Green Monster Property and conducted initial groundwork in 2022 that included reconnaissance geologic mapping, surface rock sampling, soil sampling, and a drone magnetic survey. Channel sampling across the exposed back of a raise off the main shaft returned 1.18 meters of
