Breccia Gold Project
Lemhi County Idaho
The Breccia Gold Property consists of 52 claims and is approximately 40 km southwest of Salmon, Idaho
Property History
- Two parallel trends of Au/Ag mineralization documented
- The main western Breccia Gold Zone (BGZ) on the Meadows Fault
- The eastern Musgrove Mine Trend (MMT) adjacent “Musgrove Creek Mine”
- The adjacent “Musgrove Creek Mine” was patented in 1913 and exploited high-grade Au veins within the central part of the MMT
- Gold production at the Breccia Gold Project (nee: Gahsmith Mine) was from several adits during the 1930’s and 1940’s
- At least eight historic adits were developed along the length of the mineralized zone – 4 of which are on the Property
1980s Exploration
- Extensive sampling of 1,500 by up to 20 meters wide of the BGZ from 1982 to 1985 (Groves, 1985) returned an average of 4.94 g/t Au for 40 surface samples
*The Company has not undertaken any independent investigation of the historical estimates nor has it independently analyzed the results of the previous exploration work in order to verify the accuracy of the information.
2021 CSAMT Survey
A Controlled-Source Audio-Frequency Magnetotelluric (CSAMT) survey completed in 2021 delineated two prominent north-northwest-trending resistivity corridors extending across the Property. These resistivity anomalies are interpreted to represent silicified, structurally controlled zones associated with gold-silver mineralization.
Modeling of the CSAMT data identified:
- Broad high-resistivity features (300–500 ohm-m) coinciding with known surface mineralization at the Breccia Gold Zone (BGZ).
- A continuous resistive structure extending along the Meadows Fault Zone, suggesting potential for parallel or splay mineralized zones to the north and east.
- A deep, high-resistivity body (>1,000 ohm-m) at depth beneath the BGZ, interpreted as a possible intrusive source and heat driver for the epithermal system.
This geophysical framework establishes a clear exploration vector that aligns with drill results on claims the Property surrounds in the central portion of breccia trend.
- Zone of anomalous CSAMT data is complex (100 – 200 ohm-m) and extends across the Property,
- Breccia Zone may correlate with 300-500 ohm-m range,
- Near vertical component locally exceeds 500 metres,
- A series of northerly striking faults are associated with the anomalous CSAMT data,
- Large resistivity anomalies (> 1000 ohm-m) at depth may represent a buried intrusive system
- *Note the drill holes mentioned below are not part of the 52 claims contained in the Breccia Gold Project
Deposit Model
- Low Sulfidation, Hot Spring Type Epithermal Deposit
- Characterized by large tonnage, structurally controlled deposits
- Typical for multiple episodes of brecciation, hydrothermal activity and deposition; often higher-grade root zones present at depth
- *Preservation is key
- Breccia Gold Zone mineralization displays characteristics consistent with a low-sulfidation epithermal system
- Notable examples:
- Hishikari, Japan (7.7 million oz Au*);
- Fruta del Norte, Ecuador (Lundin Gold),
- Kupol (Kinross), Waihi (3.0 million oz Au*)
