True North Copper Limited (ASX:TNC) (True North, TNC or the Company) is pleased to announce an update to the Mineral Resource at Wallace North, part of its Cloncurry Copper Project (Queensland), following the completion of an Advanced Grade Control (AGC) drilling and historic core re-assay program.
HIGHLIGHTS
Summary of JANUARY 2024 Wallace North JORC 2012 Resource:
All figures are rounded to reflect the relative accuracy of the estimates. Totals may not sum due to rounding.
True North Copper’s Managing Director, Marty Costello said:
“The recently completed Wallace North grade control drilling program has resulted in a significant 300% increase in Indicated mineral resources.
Having most of the mineral inventory (90%) now classified as Indicated Resources, greatly increases our confidence and allows for a conversion to Probable Reserves of the economically viable material following mine-design.
We look forward to announcing the Wallace North Reserve shortly and subsequently the finalised Cloncurry Copper Project mine plans.”

Wallace North Resource Update Summary
TNC engaged Encompass Mining Pty Ltd (Encompass), to update the geological model and mineral resource for the Wallace North (Cu /Au) deposit to include 142 advanced grade control reverse circulation (RC) holes for 7,594m completed by TNC in September 2023 (refer to TNC ASX Announcement, 7 November 2023, Wallace North AGC drilling hits 14.05% Cu, 25.70g/t Au; and Figure 2 & Figure 3) and 14 historic holes for 731 samples where results had been received for a TNC resampling program of historical diamond drillholes with QAQC issue (see JORC Table 1 for more details; Figure 2 & Figure 3).
The updated Wallace North Copper Project Mineral Resource (Table 1) has been classified and reported in accordance with the JORC Code, 2012 edition. Resource classification is based on confidence in the geological domaining, drill spacing and geostatistical measures. The Resource has been reported with Indicated and Inferred levels of confidence mainly based on robustness of mineralisation, data density and an overall Cu mineralisation envelope.

Sun Summit Minerals Corp. (TSXV: SMN) (OTCQB: SMREF) ("Sun Summit" or the "Company") is pleased to announce the commencement of its $6 million 2025 project-wide exploration program at the JD Project, Toodoggone Mining District, north-central British Columbia. Over 5,000 meters of drilling together with geophysical and geochemical surveys are designed to focus on target advancement, target generation and discovery.
Highlights and Next Steps:
Niel Marotta, CEO of Sun Summit Minerals, commented: "We are very excited to have kicked off our 2025 exploration season at our JD project, which is fully funded by the proceeds of our recently completed private placement. The Toodoggone region in north-central British Columbia is one of the hottest mineral exploration districts in Canada, and has seen heightened corporate activity, combined with a large influx of capital. We expect plenty of news flow coming from the Toodoggone over the summer and fall, including drill results from our own aggressive 5,000 metre program."

JD Exploration Program
Crews have mobilised to the Toodoggone District to commence the 2025 JD Project exploration season (Figure 1). The primary goal for 2025 multidisciplinary exploration program is to advance and expand the epithermal-related Creek and Finn gold-silver targets through a series of systematic step-out holes, and to generate and refine new priority targets across the highly-prospective 4.5 km long Finn to Creek corridor, as well as the 12 km long JD porphyry trend (Figure 2).

Creek Zone: Drilling at the Creek Zone (Figure 2) is designed to investigate the lateral and vertical extent of high-grade and bulk-tonnage gold mineralization (e.g., 122.53 m of 2.11 g/t Au, including 20.0 m of 10.01 g/t Au, and including 1.52 m over 121.0 g/t Au, CZ-24-004, Figure 3, see October 2, 2024, news release). Based on new geological and structural modelling, a series of steeply-dipping, northwest trending parallel vein sets with associated halos of disseminated gold mineralization have been defined. Over 3,000 meters across 10 to 12 drill holes are planned to systematically test the vein-controlling structures on 50 to 100 meter pierce-points covering a strike-length of over 700 meters (Figure 3) and a down-dip extent of over 200 meters. Results from this phase of drilling should inform grade continuity, the scale of the epithermal system and where follow-up deeper and/or step-out holes are warranted.

Finn Zone: Drilling at the Finn Zone is designed to expand the footprint of high-grade, near-surface base metal-rich gold-silver mineralization intersected in historical drilling (e.g., 35.7 m of 7.26 g/t Au including 1 m of 215.4 g/t Au in hole JD95-0472). Based on an extensive compilation of over 300 historical drill holes, a new geological and structural model suggests that epithermal-related gold-silver mineralization is hosted within veins and vein-breccias situated along a northwest striking and gently dipping volcaniclastic unit. Over 2,000 meters of drilling across 7 to 9 drill holes are planned to test the model along strike (e.g., towards hole JD13-024) and down-dip (e.g., toward JD12-015) covering a strike-length of over 650 meters (Figure 4). Drilling near the higher-grade core may also be completed to verify historical grades, confirm structural controls and explore at depth to assess the geometry and grade of the mineralized footwall zone (e.g., JD12-0093).

Target Generation: Project-wide exploration activities are aimed at target generation and drill target refinement.
Timeline: Crews have mobilised to site with camp construction, geological mapping, IP Geophysics, and drill pad construction now underway. Drilling at the Creek Zone is anticipated to begin by mid-July, at the latest.

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.
About Sun Summit
Sun Summit Minerals (TSXV: SMN) (OTCQB: SMREF) is a mineral exploration company focused on the discovery, expansion and advancement of district scale gold and copper assets in British Columbia. The Company's diverse portfolio includes the JD Project in the Toodoggone region of north-central B.C., and the Buck Project in central B.C.
