Toodoggone Overview

Sun Summit Minerals holds a district-scale land package in the Toodoggone mining district of north-central British Columbia — a re-emerging mineral belt with a strong track record of gold and copper discovery and production. The district sits within the world-class Stikine Terrane, a geologically productive region comparable to BC’s Golden Triangle, and is recognized as a Tier 1 mining jurisdiction with established infrastructure and a mining-friendly regulatory environment.

Sun Summit’s three Toodoggone projects — JD, Theory, and Orbit — cover a combined 31,500 hectares and are prospective for both epithermal gold-silver and porphyry-related copper-gold mineralization. The land package is surrounded by active exploration and development projects, including Thesis Gold & Silver’s Lawyers-Ranch project, TDG Gold Corp’s Baker-Shasta and Mets projects, Amarc Resources’ AuRORA and Joy projects, Centerra Gold’s Kemess operations, and Freeport-McMoRan’s Pil joint venture.

Three Projects. Multiple Deposit Types. One District.

JD Project (15,000 ha — Flagship Gold-Silver)
The JD Project is Sun Summit’s most advanced Toodoggone asset, with 45,400 metres of drilling completed to date across several zones including the 4.5 km Creek-to-Finn Corridor. A fully funded 10,000-metre drill program is planned for summer 2026, designed to maximize ounces ahead of an inaugural Mineral Resource Estimate targeted for Q1 2027.

Theory Project (10,000 ha — Early-Stage Copper-Gold)
Theory is an early-stage copper-gold porphyry exploration project with significant untested potential. A ~$750K program including airborne geophysics, IP surveys, and target definition is planned for 2026, with an inaugural drill campaign targeted for 2027.

Orbit Project (~6,600 ha — Early-Stage Gold-Copper)
Orbit is an early-stage gold-copper exploration project with significant exploration potential. Planning is underway for a 2026 exploration program. The Orbit Project claims are held 51%/49% with Eagle Plains Resources.
