Sun Summit Minerals Corp. Files Ni 43-101 Technical Report on JD Project in British Columbia
Sun Summit Minerals Corp. has filed a technical report in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects for the JD Project, located in the Toodoggone Mining District, British Columbia. The Technical Report is titled 'NI 43-101 Technical Report on the JD Property, Toodoggone Region, BC' and dated March 4, 2026 (with an effective date of January 23, 2026), which was prepared for Sun Summit by the Authors. The Technical Report showcases the extensive geological modelling and compilation work that the Company has done over the past three years. The spatial distribution of the mineral zonation, and various styles of mineralization, suggest the current drilling represents potentially a much larger system at both the Creek and Finn zones. These zones are open at depth and along strike, and indicate potential to significantly expand the project mineralized footprint. The Company looks forward to announcing positive metallurgical results in the next quarter of 2026 and results from the inaugural mineral resource estimate expected in First Quarter of 2027. The Company's exploration programs since 2024 have improved our understanding of numerous epithermal-related and porphyry-related targets across the JD Project. Detailed geological mapping across the JD Project has helped define several epithermal-related targets and has established a robust stratigraphic framework for future exploration. Drilling confirmed and expanded known zones of epithermal-related gold-silver mineralization, and tested new targets generated from geophysics and surface geochemistry. Drilling also provided first-ever oriented core and systematic downhole data through continuous sampling. Drilling at the Creek zone confirmed the presence of high-grade, epithermal-related vein-hosted and disseminated gold mineralization with successful step-out intersections demonstrating significant expansion potential. Drill results from the Finn and Ag Carbonate zones confirmed continuity of silver-gold mineralization associated with epithermal-related quartz-carbonate veining and breccias. Drilling at the Fericrete and Belle South targets evaluated previously undrilled targets, and intersected alteration and mineralization consistent with large, porphyry-related hydrothermal systems. Interpretation and modeling of new and historical drill results have identified additional targets and confirmed and expanded zones of previously identified mineralization. The Technical Report concludes there is a strong technical basis for continued exploration across the JD Project. The JD Project remains a property of merit and further exploration work is recommended. Mineralization in the Creek zone remains open along strike and at depth, and future work should continue to evaluate potential continuity within the 4,500 metre Creek-Finn Corridor. Drilling at the Finn zone confirmed the continuity of near-surface, high-grade gold-silver mineralization and the down-dip extent of disseminated, bulk-tonnage-style mineralization, which requires follow-up. Drilling at the Belle South target tested the porphyry potential of the area; the lithologies and alteration assemblages intersected suggest proximity to a significant porphyry-related hydrothermal system, which warrants follow-up drill testing. The Technical Report recommends a two phased exploration program comprising (i) CAD 6.94 million of recommended work in Phase 1, and (ii) CAD 3.92 million of work in Phase 2, for a total recommended work program of approximately CAD 10.86 million (assuming completion of both phases). Phase 1 includes resource and exploration drilling to expand on known mineralization, including 7,000 metres of drilling focused at the Creek and Finn zones. Phase 2 includes additional follow up resource and exploration drilling, including 3,000 metres to infill and expand the Creek and Finn zones, contingent on positive results from Phase 1. Additional geological mapping, soil and rock geochemistry, ground IP geophysical surveys, and airborne geophysics are recommended to investigate the full extent of the project area, with more focused work at targets identified in Phase 1. The information presented herein is derived from the Technical Report. The Technical Report summarizes the geology, areas of mineralization, historical exploration, and recent work completed on the JD Project by the Company, and provides recommendations for additional work. Samples referenced in the Technical Report were collected through industry-standard exploration methods, including prospecting, soil sampling, channel sampling, and diamond drilling programs. These samples were prepared, processed, and analyzed at accredited laboratories using appropriate analytical techniques, including ICP-based multi-element methods. Quality assurance and quality control procedures included the insertion of certified reference materials, blanks, and duplicate samples at regular intervals throughout the sampling process, in addition to internal laboratory QA/QC protocols. Based on these procedures, the analytical results are considered reliable for the purposes of this disclosure. Certain information disclosed herein relating to historical exploration activities conducted by previous operators is historical in nature. A qualified person has not verified this data, and therefore it should not be relied upon. However, the Company considers such information relevant as an exploration guide in assessing the mineralization potential of the JD Project. The authors of the Technical Report are Andrew Turner, P.Geo., and Emily Laycock, P.Geo., of APEX Geoscience Ltd. Each of the Authors is a 'qualified person' and independent of Sun Summit. The Authors have collectively 50 years of geological experience and have been involved in all aspects of mineral exploration and mineral resource estimations for precious and base metal mineral projects and deposits, in particular, extensive experience in epithermal gold-silver mineralized systems in the Toodoggone region of British Columbia. Mr. Turner conducted a site visit of the JD Project for verification purposes on October 14, 2025. This site visit was completed with the objective of verifying the reported geology, alteration, and mineralization of the JD Project, and to independently collect verification samples to be submitted for assay. Ms. Emily Laycock has been extensively involved in planning and field execution of the Company's exploration programs at the JD Project since 2024.
