JD-Theory – Sun Summit Minerals

JD-Theory Project Overview

The JD and Theory projects are located in the Toodoggone mining district of north-central British Columbia—an emerging, deposit-rich mineral belt with exceptional exploration potential. Together, the projects cover over 25,000 hectares and are strategically positioned near several active exploration and development sites, including Thesis Gold’s Lawyers and Ranch properties, TDG Gold’s Baker-Shasta projects, Amarc Resources’ AuRORA Project, Centerra Gold’s Kemess East and Underground projects, and the past-producing Kemess South open-pit copper-gold mine.

This highly prospective land package is geologically favorable, hosting both high-grade epithermal gold-silver and porphyry-related copper-gold mineralization. Although historical work—including drilling, geochemical sampling, and geophysical surveys—has been conducted, much of the property remains underexplored, presenting significant opportunity for discovery.

Geology & Mineralization

The Toodoggone district hosts a significant number of shallow, high- and low-sulfidation epithermal-type mineral deposits and occurrences (e.g., JD, Lawyers, Shasta, Baker) as well as porphyry-related mineralization (e.g. Kemess, Brenda, Pine) that may be contemporaneous and potentially cogenetic. These deposits are hosted by a thick (>2 km) succession of well-preserved, Early Jurassic sub-aerial andesitic and dacitic volcanic rocks of the Toodoggone Formation (Hazelton Group).

The JD Project is characterized by both high-grade epithermal gold and silver mineralization, as well as porphyry-related copper and gold mineralization. The epithermal-related systems, locally dispersed over a ~5 km east-west trend, are poorly explored and represent high-grade gold and silver mineralization potential.

JD Project – Creek Zone

Limited drilling (PDF), mineralization open in most directions
2024 program confirmed presence of continuous disseminated mineralization from surface
Anomalous surface geochemistry proves near-surface potential
IP geophysics confirmed chargeability and resistivity highs that require further testing

JD Project – Finn Zone

Broad zone of near -surface, epithermal -related gold -silver mineralization
Structurally controlled mineralization
Prior drilling in high grade core; subsequent drilling confirmed continuity of mineralization

Theory Project

23 mineral claims covering 9,676 ha
Adjacent to JD Project with similar geology to Thesis Gold’s Ranch-Lawyers
Helicopter-accessible; upgraded road access within 8 km (via Thesis Gold, 2023)
Geology primarily comprised of lower Jurassic Hazelton Group volcanics (Toodoggone Formation, same host rock as the JD Project) which unconformably overlie late Triassic Takla Group volcanics.
Project straddles the “red-line” unconformity—a key marker for major deposits in the region: The Red Line refers to a regional geological contact first highlighted by the BC Geological Survey in a 2014 study. Specifically, it marks the contact between the Stuhini Group (Upper Triassic volcanic and sedimentary rocks) and the overlying Hazelton Group (Lower Jurassic volcanic and sedimentary rocks). This boundary is called the Stuhini-Hazelton contact, and it represents a major arc transition formed during the accretion of the Stikine Terrane. Many major porphyry and epithermal deposits in the Golden Triangle cluster near this contact, including KSM (porphyry Cu-Au – Seabridge Gold), Brucejack Mine (epithermal Au – Newmont), and Red Chris Mine (porphyry Cu-Au – Newmont).
Historical work (1980s) documented occurrences of low-sulphidation epithermal-related mineralization including:
- quartz-barite veins with up to 8.2 g/t Au, 195 g/t Ag, and 6.2% Cu at the DM occurrence (BC Minfile 094E 231)*;
- and a quartz carbonate vein system with up to 6.8 g/t Au and 1,480 g/t Ag at the Fred-1 occurrence (BC Minfile 094E 402)*.
- The BEV occurrences (BC Minfile 094E 259)*, interpreted as a Cu-Au porphyry target, returned select historical rock results up to 0.47% Cu, 10.5 g/t Ag, and 0.13 g/t Au
- Detailed soils revealed a 1.6 by 2 kilometre copper-in-soil anomaly with peak soil results to 920 ppm Cu.
- Very little work is documented in the south and eastern parts of the property.
2024 airborne magnetic & radiometric survey identified a 13 x 13 km prospective area for integration with historic data
