Vancouver, British Columbia--(Newsfile Corp. - June 8, 2026) - Sun Summit Minerals Corp. (TSXV: SMN) (OTCQB: SMREF) ("Sun Summit" or the "Company") is pleased to announce that its fully funded, 2026 exploration drill program at the JD Project, Toodoggone Mining District, north-central British Columbia has now started. Over 10,000 meters of drilling is planned across the Creek and Finn zones.
Highlights:
Transformational Drill Program Has Started: One drill rig is currently in operation kickstarting a significant 10,000 meter drill program, with a second drill rig set to begin operating in the coming days.
Focused and Systematic Drill Program: Results from the carefully planned 2026 drill program will contribute to an inaugural mineral resource estimate ("MRE") planned for Q1 of 2027.
Creek Zone Targeted Drilling: Drilling at the Creek Zone will include step-out and infill drill holes designed to investigate the extent and continuity of near-surface, high-grade and bulk-tonnage gold mineralization. Drilling will follow-up significant 2024 and 2025 results, including 81.0 meters of 4.80 g/t gold, including 34.0 meters of 9.07 g/t gold in drill hole CZ-25-021 (November 25th, 2025, News Release).
Finn Zone Targeted Drilling: Drilling at the Finn Zone will include step-out, infill and exploration drill holes designed to investigate the extent and continuity of near-surface bulk-tonnage gold-silver mineralization. Drilling will follow-up significant historic and 2025 results, including: 17.0 meters of 2.31 g/t gold with 113.1 g/t silver, including 6.0 meters of 5.30 g/t gold with 157.9 g/t silver in drill hole FZ-25-002 (January 22nd, 2026, News Release).
Project-Wide Geophysical Surveying Underway: An airborne mobile magnetotelluric ("MobileMT") survey is underway across the entire JD Project. The goal of the survey is to investigate the scale of alteration zones of known targets as well as identify new target areas.
"We are excited to have officially launched our fully funded 10,000 meter drill program at our JD Project," said Niel Marotta, CEO of Sun Summit Minerals. "This program will include the most significant drilling at JD since the late 1990s. The 2026 program is the largest drill program planned since Sun Summit optioned the JD property in 2024, and represents more meters of drilling at JD than the last two drill seasons combined. Importantly, this program will drive the JD project towards an inaugural mineral resource estimate, expected in Q1 of 2027."
Fully Funded 10,000 Meter Drill Program
The recently commenced, 10,000-meter drill program at the JD project has been carefully planned with drill holes designed to contribute to an inaugural MRE for the Finn and Creek zones, anticipated to be released in Q1 of 2027 (see May 5th, 2026 News Release).
Details of the 2026 drill program include:
- Up to 5,000 meters of drilling is planned at the Creek Zone to systematically evaluate the modelled vein-controlling structures covering a strike-length of over 600 meters and a vertical extent of over 350 meters. Results from this phase of drilling at the Creek Zone should inform grade continuity, the down-dip and strike extents of mineralization, and the presence of additional high-grade zones (e.g., 34.0 meters of 9.07 g/t gold in drill hole CZ-25-021).
- Up to 5,000 meters of drilling is planned at the Finn Zone to systematically evaluate the down-dip and strike-extent of the favorable, and well mineralized, volcaniclastic unit. Drill holes will cover a footprint of approximately 650 meters by 350 meters primarily down-dip from the densely drilled core of the mineralized zone. Results from this phase of drilling at the Finn Zone should inform grade continuity, the down-dip and strike extents of mineralization, verify historical data and evaluate the structural controls on high-grade silver mineralization central to the target (e.g., 6.0 meters of 5.30 g/t gold with 157.9 g/t silver in drill hole FZ-25-002).
One drill rig is currently in operation, focused on the Creek Zone. A second rig is set to begin operating in the coming days. One of the drill rigs will move to the Finn Zone in the coming weeks once drill pads at Finn are constructed.
Target Generation
A project-wide airborne (MobileMT) survey has commenced across the entire JD Project. The survey consists of 740 line kilometers on 250 meter spaced, northwest-southeast oriented lines. The objective of the survey is to image subsurface resistivity/conductivity to a depth of approximately 1 to 2 kilometers. The purpose of the survey is to investigate the scale of broad and locally concealed alteration zones associated with known targets as well as to identify new target areas.

The areas marked by the dashed yellow ovals will be the focus for the majority of the 2026 drilling. Targets between will be ranked and prioritised for potential drill testing.

About the JD Project
The JD Project is located in the Toodoggone mining district in north-central British Columbia, a highly prospective deposit-rich mineral trend. The project covers an area of over 15,000 hectares and is in close proximity to active exploration and development projects, such as Thesis Gold and Silver Inc.'s Lawyers and Ranch projects, TDG Gold Corp's Baker-Shasta projects, Amarc Resource Ltd.'s AuRORA project, Centerra's Gold Inc's Kemess East and Underground projects, as well as the past-producing Kemess open pit copper-gold mine (Figure 2).
The project is 450 kilometres northwest of the city of Prince George, and 25 kilometres north of the Sturdee airstrip. It is proximal to existing infrastructure in place to support the past-producing Kemess mine, including roads and a hydroelectric power line.
The JD Project is in a favourable geological environment characterized by both high-grade epithermal gold and silver mineralization, as well as porphyry-related copper and gold mineralization. Some historical exploration, including drilling, geochemistry and geophysics, has been carried out on the property, however the project area is largely underexplored.
