Black Ridge VMS Copper Discoveries Moving Upwards from their Magna Chambers to the Surface....why there is an excellent chance that high grade copper-Gold- Silver-zinc extends below the surface outcroppings at Black Ridge
An excellent recent article on the VMS deposits , their classification and formation signatures in the Lushes Bight Formation of NL ...VMS is formed deep in the bowels and is forced upwards by gravity differentials
See Fig 1 for their upward to surface development process and Fig 2 for their classification types .....Black Ridge is mafic while Ming is bimodal mafic as is also Whakesback and Little Deer
Very technical but the Figures illustrate quite well the forced upward move and entrainment of metals to the surface
