F3 Gold is owned and operated by two successful, motivated geologic entrepreneurs with a passion for science and the outdoors. We are proud to operate with sound environmental stewardship and social responsibility in our pursuit of mineral discoveries. All of our exploration activities are conducted in strict accordance with State and Federal regulations.

Our long-term vision and care for ecosystems drive our commitment to sustainable business practices and ethical decision-making.


We build partnerships that utilize local talent and resources, ensuring growth and investment in local communities.


We hire well-qualified local personnel whenever possible, and partner with Universities to create learn-work opportunities for students.


F3 Gold’s project is located in the Black Hills region of South Dakota.  We have been focused on re-developing the geologic model to explore for gold throughout the Black Hills district.  Our interest and research in this region began in university and has continued ever since. The project takes a district-scale approach to understanding the geology and relationships to gold throughout the entire Black Hills.



Q: Are you a mining company or planning to mine in the Black Hills? 

A: No, we are not a mining company. We are an exploration and prospecting company!  Our focus is on staking prospective ground to evaluate the geology, with the goal of locating a high-grade, underground, gold deposit.

Q: What is exploration?

A: Exploration is the systematic process of studying the geology, collecting data and evaluating the potential for minerals.  Simply put, Exploration is Scientific Prospecting!

Q: How many exploration projects become a mine?

A: Statistically, less than 3% of all exploration projects ever become a mine.

Q: What is F3 Gold looking for in their Black Hills project?

A: We are looking for gold and other associated precious metals, such as silver.

Q: Why are you looking for gold and precious metals in the Black Hills? 

A: The Black Hills is a historical mining district with a significant geology and gold production. F3 Gold has been studying the geology and working with new science to better understand a new approach to exploring for gold in this world famous district.

Q: Hasn’t all the gold in the Black Hills already been found? 

A: We believe that it is very unlikely all the gold has been found. Our new science and geology model strongly suggests there could be gold hidden deep underground.

Q: Will there be an open pit like Wharf & Homestake?

A: Our model suggests if any gold deposit is found, it would be deep underground and not likely to be mined with an open pit.

Q: Is your project going to be using water from Rapid Creek? 

A: No, F3 Gold will not source any water from Rapid Creek, or any other creek in the Black Hills.

Q: Have you found gold at any of your sites in the Black Hills?  

A: So far, the geology we have examined supports the new model for the region as favorable to host an underground gold deposit.  To date, F3 Gold has not discovered a gold deposit.

Q: How are you working with the local communities in the region?   

A: F3 Gold has a variety of initiatives in place for working with the local communities, including:

  1. Supporting local Youth through the YMCA and the Boys & Girls Clubs
  2. Supporting the local Volunteer Fire Departments
  3. Working with the USFS
  4. Meeting with local residents and community leaders
  5. Planning future engagement with tribal communities

Q: What impacts will your project have on the environment? 

A: Exploration activities have very minor, or no environmental impacts. We do this by limiting our exposure to creeks and lakes; limiting our surface disturbance; planting trees to replace ones that may be removed; and working with the Forest Service, BLM and Department of Environment and Natural Resources, and local groups to ensure our activities abide by environmental best practices.

Q: What makes F3 Gold different from other exploration companies? 

A: F3 Gold is a small private gold exploration company based in Minnesota. Our project in the Black Hills was born from our love of geology and recreation.  We are proud to have strong environmental stewardship and social responsibility, and as a group of young and passionate geologists, we see opportunity in being the future of our industry.  Our strong values and new age thinking are a testament to who we are and our project.
