CBC Property: A Compelling Porphyry-CRD System
The Come By Chance (CBC) property displays all the hallmarks of a significant porphyry copper-gold system with exciting CRD (Carbonate Replacement Deposit) potential, representing a prime exploration opportunity in southern British Columbia’s prolific Quesnel Terrane.
B.C. Porphyry Belt
Over 80% of the world’s copper production comes from large-scale open-pit porphyry copper mines.
In Canada, British Columbia enjoys the lion’s share of porphyry copper/ gold mineralization.
These deposits contain the largest resources of copper and 50% of the gold in the province.
The Prolific Greenwood Mining District
The prolific Greenwood mining camp of southern British Columbia is considered to be one of the most concentrated mineralized areas in western North America with over 30 past producing mines, each only scratching the surface.
B.C. Porphyry Belt
High-gold and copper values at surface are indication of rising hydrothermal fluids via structures/fractures from a concealed mineral-bearing intrusive.
Crook Lake Caldera is an indicated collapsed breccia, an ideal location for the deposition of circulating mineral-bearing hydrothermal fluids.

Dual-System Evidence
Our property demonstrates compelling geological characteristics supporting both models:
Porphyry Indicators:
-
Initial drilling confirmed porphyry-style alteration, veining and mineralization across a substantial area
-
Extensive propylitic alteration halos encountered in all drill holes, a classic signature of porphyry systems
-
Significant pyrite mineralization (up to 20%) forming potential halos around a concealed porphyry core
-
Geophysical signatures showing characteristic zonation patterns around a potential mineralized center
CRD-Skarn Potential:
-
Brooklyn Formation limestone units providing ideal host rocks for replacement mineralization
-
Monzonite & syenite intrusions serving as potential sources of metal-bearing hydrothermal fluids
-
Major structural controls (Eagle Fault and Lind Creek Fault) acting as fluid conduits
-
High-grade surface samples (up to 17.05 g/t Au and 6.74% Cu) indicating robust mineralization
-
Skarn alteration assemblages identified in drilling
Geophysical data clearly vectors toward the heart of this system, with Crook Lake potentially representing a collapsed breccia – ideal for concentrated mineral deposition. Our systematic exploration approach continues to build evidence for a potentially significant discovery at the intersection of these complementary mineralization styles.
2022 Drilling Intercepts Extensive Propylitic Alteration ‘Halo of Porphyry’
Alteration Zoning provides clues to hidden ore bodies.
Provides Vectors Towards Potential Porphry Core
- Copper-gold porphyry deposits are generally characterized by an association with porphyritic intrusions, by overprinting Propylitic, Phyllic and Potassic alteration.
- Propylitic alteration, characterized by the occurrence of chlorite and epidote, is typically the most extensive and peripheral alteration facies developed around porphyry ore deposits.
- Belmont’s CBC copper-gold porphyry target has all the key elements enabling it to vector towards the core of a potentially large porphyry system.
Q2 – 2025 Drilling
- The 2025 drill program is designed to effectively tests both the CRD model (with holes targeting limestone replacement zones and structural conduits) and the porphyry-skarn model.
