Corral Copper

 
  • An advanced stage, 100% controlled copper project in Arizona
  • Over 50,000m of historical drilling has been completed within the district, with near surface mineralization of copper, silver, zinc and gold, including 126.2 metres of 1.24% copper
  • Robust land package of over 9,600 acres (15 square miles) of mineral rights including over 1,800 acres of Patented mining claims and surface rights
  • Anglo American retains an interest on a portion of the project

 
 
  • The Corral Copper Project is located in Cochise County, Arizona, 15 miles east of the famous mining town of Tombstone and 22 miles north of the historical Bisbee mining camp which has produced more than 8 billion pounds of copper with grades of up to 23%. Production from the Bisbee mining camp is not necessarily indicative of the mineral potential at the Corral Copper Project.
  • Corral Copper consists of 9,600 acres (15 square miles) of mineral rights including over 1,800 acres of Patented mining claims and surface rights.

  • The district has a mining history dating back to the late 1800s, with several small mines extracting copper from the area in the early 1900s, producing several thousand tons with grades up to 9.2% copper ore. Between 1950 and 2008, various companies explored parts of the district, but the effort was uncoordinated, non-synergistic and focused on discrete land positions and commodities due to the fragmented ownership. Intrepid has been able to secure data from various sources which provides a solid foundation in creating geological interpretations and identifying new target areas.
  • Anglo American began exploring in the district in 2016, conducted mapping and airborne geophysics which identified numerous new target areas through the district. Intrepid has acquired Anglo American's data package and in exchange, Anglo American has retained an interest over a portion of the project area in the form of a right of first refusal over transfers if certain conditions are met.
  • Over 50,000m of historical drilling has been completed within the district, with several significant near surface drill intercepts, including 126.2m (30.4m to 156.6m) of 1.24% copper in Drill Hole 20_01. Additional drill results are identified below. This drill result is historical in nature. Intrepid has not undertaken any independent investigation ofthe sampling nor has it independently analyzed the results of the historical exploration work in order to verify the results. Intrepid considers these historical drill results relevant, as the Company will use this data as a guide to plan future exploration programs. Intrepid also considers the data to be reliable for these purposes; however, the Company’s future exploration work will include verification of the data through drilling.

Note:  Drill intercepts are reported from historical drilling.  Intrepid has not yet undertaken any independent investigation of the sampling nor has it independently verified the results of the historical exploration work. Intrepid considers these historical drill results relevant, as the Company will use this data as a guide to plan future drill programs. Composite drill intervals where reported were tabulated using a minimum 3-meter length, no cut-off, with a minimum grade of 0.2% copper. All intervals are core lengths, and true thicknesses are yet to be determined. Intrepid also considers the data to be reliable for these purposes; however, the Company's future exploration work will include verification of the data through drilling.

 
 
 

No core remains from the previous drill programs, however Intrepid has compiled a robust data set of drill logs and assay data from the previously drilling. Intrepid intends to complete confirmation drilling based on the historical results to allow it to utilize the historical drill data and move towards a NI 43-101 resource estimate.

Intrepid is confident that by combining modern exploration techniques with historical data and with a clear focus on responsible development, the Project can quickly become an advanced exploration stage project and move towards feasibility level studies.
