  • Concessions are located adjacent or within proximity to Cerro Caliche gold project in Sonora, Mexico.
  • Strategic opportunity to demonstrate Cerro Caliche as part of a larger gold epithermal system, with wide-scale potential to host multiple mineralized zones. 
  • Potential to build Cerro Caliche into a district-scale gold mineral project with multiple major mineralized zones.
  • Numerous exploration programs conducted across the new concessions resulting in multiple mineralized targets.
  • 100% interest in 24 mineral concessions over 5,025.21 ha for USD $6.0 million payable in installments over twenty months:
    • Plus payment of outstanding mineral concession fees totaling approximately USD $990,000. 
    • No issuance of any securities or any grant of a royalty interest.
    • Extensive historical data from multiple exploration programs conducted over the past 30 years. 
    • Soil and rock geochemical samples, surface and underground workings, drilling campaigns and geophysical surveys been completed. 
    • Concession hosts various veins and mineralized structures with potentially similar geological, structural and mineralized characteristics as Cerro Caliche.
  • Up to a 51% interest in 5 mineral concessions over 453.91 ha for up to USD $9M in exploration expenditures over four years:
    • Will earn 12.75% interest for each USD $2.25M of exploration expenditures incurred.
