Breccia Gold Project

Lemhi County Idaho​

The Breccia Gold Property consists of 80 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

 The CSAMT data suggest two sub-parallel, north-northwest trending zones of precious metal mineralization are present –  a West Zone’ and an East Zone.

The survey identified a prominent NW-SW trending resistive feature to the east, in contrast to a very low resistive unit which dominates the western portion of the Property.

This extensive zone of resistivity corresponds to the high-grade gold and silver mineralization identified in drill core, surface rocks, and soil samples.  Highlights include:

  • 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 80 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*)
