Sampling was completed to produce more reliable data via channel sampling than the rock chip sampling and to expand the sampling done in 2020.

Key Points: 
  • Sampling was completed to produce more reliable data via channel sampling than the rock chip sampling and to expand the sampling done in 2020.
  • In general the channel sampling data provides a more reliable sample due to increased depth penetration into the rock and more consistent systematic sampling than standard rock chip sampling with a rock hammer.
  • Gold was determined by fire assay with an ICP finish, over limit samples were determined by fire assay and gravimetric finish.
  • To find out more about Black Mountain Gold USA Corp. please contact Investor Relations at (604) 662-8184 or email [email protected] .
