Doubleview Advances 2026 Drill Program At Hat; Three Independent Target Methods Converge on Four Priority Locations - Pad 1 Mineralization Intersected, Drilling Advances to Pad 2
Doubleview Gold Corp. provided an update on its 2026 drill program at its 100%-owned Hat polymetallic porphyry project in northwestern British Columbia. Drill holes H109 through H112 at Pad 1, East of the Hat deposit, have reached their intended depth targets, with drill core intersecting Hat-style mineralization consistent with the broader mineralized system. Assay results are pending. The Company is now advancing drilling operations to Pad 2, Southwest of the Hat deposit. Drill target locations for the 2026 program were developed through three independent technical methods. Four priority drill pad locations, Pad 1, Pad 2, Pad 3, and Pad 4, were consistently identified by all three methods, providing an exceptional level of convergence and geological confidence. The selected locations are designed to expand the mineral resource envelope and upgrade Inferred mineral resources toward the Indicated and Measured categories required to support a Pre-Feasibility Study. Drilling at Pad 1 (H109-H112) has reached intended depth targets with Hat-style mineralization intersected in drill core. Assay results are pending. Three independent target methods, geological interpretation, quantitative resource confidence assessment (conditional simulation), and AI-assisted geophysical analysis, all identify the same four priority pad locations. The convergence of all three independent methods on four common locations provides an exceptional level of geological confidence underpinning the 2026 drill program. Drill locations are designed to expand the mineralized footprint and upgrade Inferred mineral resources toward Indicated and Measured categories in support of future Pre-Feasibility Study requirements. Doubleview has released an interactive three-dimensional technical database of the Hat deposit, available at https://www.doubleview.ca/wp-content/uploads/2026/07/Hat_3D_Database-v2.html (desktop browser recommended). The Company is advancing drilling operations to Pad 2. The Company pursued an accelerated, data-intensive approach to target selection for the 2026 drill program, with the objective of maximizing geological confidence in a single exploration season. Three complementary and independent target-generation methods were applied: Geological Interpretation. Doubleview's geological team developed drill targets through an integrated review of the deposit's geological model, drill hole data, core logging, structural framework, alteration patterns, and the spatial distribution of mineralization. Target locations were selected to address areas with limited drill coverage and to test the lateral and depth continuity and expansion potential of the mineralized system. Resource Confidence Assessment. Tomasz Wawruch, FAusIMM, of Mineit Consulting Inc., completed an independent quantitative resource confidence assessment using conditional simulation techniques. The study identified priority drill locations where additional drilling would most effectively reduce estimation uncertainty and support reclassification of mineral resources from Inferred toward Indicated and Measured categories, specifically those required for a defensible Pre-Feasibility Study. AI-Assisted Geophysical Analysis. Doubleview commissioned DrillTargetAI to perform a systematic review of the Hat Project's induced polarization (IP) geophysical dataset. The analysis identified zones where high chargeability coincides with low resistivity, a signature consistent with the sulfide-bearing, copper-mineralized systems already confirmed at Hat. Candidate zones were restricted to areas located more than 180 metres from existing drill collars to prioritize untested ground, and were distributed across the target area to ensure targets test distinct portions of the anomaly. The analysis is grounded entirely in the Project's own geophysical data, rather than external or generic models. The four priority pad locations, Pad 1, Pad 2, Pad 3, and Pad 4, represent locations where all three independent methods identify targets in close spatial agreement. This convergence provides a robust foundation of geological confidence for the 2026 program and serves as an independent validation of the coherent nature of the Hat mineralizing system. The Hat Project hosts a Mineral Resource Estimate with an effective date of February 25, 2026, comprising 609 Mt of Measured and Indicated Resources at 0.43% CuEq and 503 Mt of Inferred Resources at 0.41% CuEq (as previously disclosed February 25, 2026). Mineral resources are not mineral reserves and do not have demonstrated economic viability. The substantial Inferred resource component represents a meaningful opportunity to advance resource confidence through targeted, systematic drilling. The 2026 drill program is designed to provide the geological continuity and data density required to support conversion of Inferred resources to Indicated and Measured categories, and to test the expansion potential of the mineralized system beyond the current resource envelope in support of future engineering and economic studies. Doubleview has published a browser-based interactive three-dimensional technical database of the Hat deposit, incorporating drill hole data, geological interpretation, and resource modelling. The database is available to investors and technical stakeholders at https://www.doubleview.ca/wp-content/uploads/2026/07/Hat_3D_Database-v2.html (desktop browser recommended). The Company believes this tool provides an unprecedented level of transparency and technical insight into the scale and character of the Hat mineralized system. Tomasz Wawruch, FAusIMM, Senior Geology and Mineral Resource Consultant at Mineit Consulting Inc., is a Qualified Person as defined by National Instrument 43-101, Standards of Disclosure for Mineral Projects. Mr. Wawruch has reviewed and approved the technical content of this news release. He is independent of Doubleview.
