Sun Summit Minerals Corp. (TSXV: SMN,OTC:SMREF) (OTCQB: SMREF) ("Sun Summit" or the "Company") is pleased to report results from a recently completed induced polarization (IP) survey across the JD Porphyry Trend at the JD Project, Toodoggone Mining District, north-central British Columbia.
Highlights:
New IP data enhances the JD Porphyry Trend: New chargeability and resistivity data demonstrate strong prospectivity for porphyry-related copper-gold mineralization along the JD Porphyry trend.
Untested anomalies: Only 850 meters of the 8.5 km long chargeability anomaly has been tested by drilling, where all 5 widely-spaced holes from 2013 and 2018 intersected porphyry-related alteration and mineralization (see February 5th, 2025, news release).
Follow-up programs ongoing: Geological mapping and prospecting surveys along the McClair Creek alteration zone are ongoing. Data from recently completed soil surveys along parts of the JD Porphyry trend are being compiled and interpreted to refine drill targets.
Phase II IP Survey: a subsequent phase of closely-spaced IP survey south of the Creek Zone is newly completed and results are being integrated with the 2024 IP survey historical data and with the current 3D model of the Creek zone.
"We have now defined a broad 8.5 km long chargeability-high anomaly at JD, significantly enhancing the project's copper-gold porphyry potential along the McClair Creek alteration zone," said Niel Marotta, CEO of Sun Summit Minerals. "This impressive alteration zone transects the JD Porphyry trend, yet remarkably, only five historic drill holes have tested it. The vast majority of this large-scale anomaly remains untested and represents a high-priority area for further target definition and exploration."
The JD Porphyry Trend IP Survey
The IP survey across the JD Porphyry trend consisted of over 31-line kilometers across eight northeast-southwest oriented lines. Line spacing varied from 500 to 1,200 meters depending on design depth of earlier survey arrays (Figure 1). The 2025 survey was designed to characterise and detect subsurface sulfide mineralization associated with pronounced magnetic anomalies and strong hydrothermal alteration observed along McClair creek (see February 5th, 2025, news release). The IP survey expanded on previous surveys that defined a north-south trending, open ended, high-chargeability anomaly. New and historic data was compiled and inverted (Figures 1 and 2).
The broadly, north-south oriented >18 mv/v McClair Creek chargeability-high anomaly spans 8.5 by ~2 kilometers and is open to the north and south (Figure 2). The broad anomaly is locally spatially coincident with discrete strong magnetic-high anomalies (Figure 2) and near the Belle South target, a strong resistivity-high anomaly. The intensity of the chargeability anomaly increases with depth, particularly to the north where the anomaly increases to +40 mv/v near the Fericrete and Oxide Peak targets (Figure 1).
Besides five widely-spaced drill holes near the McClair target in 2013 and 2018 (Figure 1), no other chargeability anomaly along the 8.5 km trend has been drill tested. Results from the five McClair holes (see February 5th, 2025 news release) suggests the entire trend may also be prospective for porphyry-related mineralization.
The McClair Creek anomaly is along trend, 17 km north of Amarc Resources' Aurora discovery (Figure 3). Porphyry-related copper and gold mineralization at Aurora is spatially associated with strong coincident chargeability-high and resistivity-high anomalies centered on a magnetic-high anomaly1.
Next Steps
This new chargeability and resistivity data supports the strong prospectivity for partially concealed, porphyry-related copper-gold mineralization proximal to the McClair Creek alteration zone (Figure 1). Additional IP surveying is warranted to infill widely spaced lines and to extend the survey footprint to the north and south (Figure 3).
Data from recently completed soil surveys along parts of the JD Porphyry trend are being compiled and interpreted to refine drill targets. Data from these surveys together with results from ongoing geological mapping and prospecting along the McClair Creek alteration zone (Figure 1) will be used to inform drill targeting and 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's Lawyers and Ranch projects, TDG Gold's Baker-Shasta projects, Amarc Resource's AuRORA project, Centerra's Gold's Kemess East and Underground projects, as well as the past-producing Kemess open pit copper-gold mine.
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.
