[{"type":"text","content":"Canstar Commences Trench Program at Mary March, Multiple Targets Include New 1.2 km IP Chargeability Trend; Reports >$1M in Warrants Exercised, Expanded Land Package and TeamToronto, Ontario--(Newsfile Corp. - September 22, 2025) - Canstar Resources Inc. (TSXV: ROX) (\"Canstar\" or the \"Company\") reports that field work at the Mary March Project (Figure 1) in central Newfoundland is accelerating, with a trenching program underway to investigate newly defined induced-polarization (\"IP\") chargeability trends, including an untested ~1.2 km long anomaly generated from the Company's geophysics compilation and located 550 metres north of the historic discovery area. Trench excavation began in early September and will be completed before the end of the month, weather permitting. The detailed trench mapping will aid in developing a 3D geological model to generate new drill targets.Initial field findings include mineralized float rock samples in the trench corridor reading up to 4% copper (\"Cu\") via portable X-ray fluorescent analyzer (\"pXRF\").1 The company expanded its claims in the vicinity of the ~1.2 km IP anomaly and added personnel to the field team. The company has also completed the deep IP Survey (in partnership with Canterra Minerals Corporation) over the Buchans project, with interpretation to follow soon.JV Technical lead Dr. Harold Gibson commented: \"Our geology-first approach is doing exactly what we set out to do—convert historical datasets into clear, testable targets. New compilation and analysis of historical geophysical data identified multiple chargeability trends, including a ~1.2 km corridor that we're now trenching. We're moving quickly to establish new, geologically constrained drill targets in this established mining district.\" HighlightsExploring a new, large IP target: A previously untested ~1.2 km long IP chargeability anomaly has been delineated 550 metres north of the historic discovery area from 2014 DCIP (\"Direct Current Induced Polarization\") data; two trenches are allocated to this anomaly for initial evaluation. IP confirmed as an effective tool or method works at Mary March: A third-party review by Hardrock Geophysics confirms DCIP is the most effective geophysical method at Mary March here (being less susceptible to interference from powerlines and the lake than other methods), with...
