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).

As demand for copper continues to rise, driven by global electrification trends, Los Andes Copper is well-placed to leverage its significant copper position in Chile, driven at the helm by a group of highly experienced technical and business leaders.
The global transition to electrification is driving surging demand for copper, a metal essential to clean energy and emerging technologies. The copper market is set to reach a CAGR of 5.4 percent during 2024-2030, projected at US$368.8 billion by 2030.
Chile, the world’s top copper producer, is a key player in meeting this demand. With its vast deposits and stable, mining-friendly environment, the country continues to attract leading mining companies.
Los Andes Copper (TSXV:LA,OTCQX:LSANF) is advancing its 100 percent-owned Vizcachitas copper-molybdenum project in Chile — one of the largest undeveloped copper assets not held by a major. Backed by an experienced management team, the company is well-positioned to help meet the world’s growing copper needs.
The company filed a positive pre-feasibility study in 2023 indicating US$2.78 billion after-tax net present value (NPV) using an 8 percent discount rate and an internal rate of return (IRR) of 24.2 percent at US$ 3.68/lb copper, US$12.90/lb molybdenum and US$21.79/oz silver, with an estimated initial capital cost of US$2.44 billion. The PFS also highlighted a construction period of 3.25 years and a payback period of 2.5 years from initial production.
The company expanded its land package by obtaining first-priority exploration claims over new areas within and adjacent to the current property boundaries for the Vizcachitas copper project.
The claims cover an 18 sq km block within the current property boundary, and another 7 sq km block adjacent to the north-east corner of the property boundary.

Questcorp Mining (CSE:QQQ,OTC:QQCMF,FSE:D910) is a Canadian junior exploration company focused on unlocking value in two high-potential mineral districts: the Sonoran Gold Belt in Mexico and Vancouver Island in British Columbia.
The company aims to build shareholder value through disciplined exploration of assets with near-surface mineralization and proven geologic continuity. The company operates in mining-friendly jurisdictions, close to infrastructure and within major metal-producing belts. Its flagship La Union gold project offers high-grade gold-silver-lead-zinc potential in Mexico, while the North Island copper project provides exposure to porphyry copper and skarn systems in a district that hosts multi-billion-pound copper resources.
With gold prices near all-time highs and a copper supply crunch emerging, Questcorp is targeting discoveries that can drive exponential value from a tightly held share structure.
The La Union gold project is a 2,604-hectare, road-accessible high-grade carbonate replacement deposit (CRD) located at the edge of the Sonoran Gold Belt, one of the richest gold-producing regions in Mexico. The property is located near major mines, including La Herradura (6.7 Moz, measured and indicated) and San Francisco (1.4 Moz, measured and indicated), and boasts historical production from underground operations by Peñoles and others, reportedly yielding ~50,000 ounces of gold in the 1950s at grades of 7 to 20 grams per ton (g/t) gold.
La Union gold project location
Work done to date includes consolidation of seven historical properties into a single district-scale project by Riverside Resources, which invested more than US$2.5 million in geological mapping, sampling and target definition. Sampling has returned high-grade grab samples including 83.2 g/t gold, 4,816 g/t silver, 30 percent zinc, and 19.8 percent lead. Channel sampling and geological work identified eight mineralized zones, three of which – Plomito, La Famosa and La Union – are drill-ready and fully permitted.
Geology and history of La Union
Questcorp executed a definitive agreement with Riverside in May 2025 to earn up to 100 percent interest in the project. The planned Phase I program includes drilling 10 diamond drill holes averaging 300 meters in depth across the three priority targets, alongside geophysical (gravity and EM) surveys to refine targets. Questcorp will also continue surface exploration at the remaining five targets to identify additional drill candidates. The project’s polymetallic nature and porphyry potential at depth suggest significant resource upside. Riverside remains as the operator during the earn-in, bringing proven success in similar deposits such as Alamos Gold’s Mulatos.
The North Island copper property is an exploration-stage project located on the northern tip of Vancouver Island, approximately 7.5 km northwest of BHP’s historic Island Copper Mine. The Island Copper operation historically produced 1.2 billion kg copper, 35,268 kg gold, 360,800 kg silver, and significant molybdenum and rhenium from 367 million tonnes of ore, underscoring the district’s endowment.
NICP hosts eight documented copper-silver skarn occurrences and displays porphyry-style mineralization associated with the Island Intrusive suite. The property is geologically anchored by two main target areas: skarns associated with Quatsino limestones in the east and a porphyry copper target to the west, known as the Marisa Zone. Historical drilling by previous operators at Marisa intersected broad zones of copper mineralization, including:
Despite promising results, these zones were never followed up. Questcorp intends to revisit and expand on this historic work. The next steps include completing a 3D induced polarization (IP) survey to model chargeability and resistivity anomalies, followed by a focused drill campaign targeting extensions of the Marisa porphyry.
The project benefits from excellent access via the Vancouver Island Highway and logging roads, plus nearby hydro infrastructure, offering low-cost exploration potential. With a favorable neighborhood, including Northisle Copper & Gold Inc. (TSXV: NCX) with a ~$300 million market cap, NICP represents a high-upside copper exploration story in a Tier-1 jurisdiction.
