What is VMS?: Volcanogenic Massive Sulphide (VMS) Deposits
A volcanogenic massive sulphide (“VMS”) deposit in its simplest form is a series of massive to semi-massive sulphide (Cu, Pb, Zn, +/- Au, Ag) lenses typically formed on or below the sea floor resulting from the circulation of metal-bearing fluids driven by a magmatic heat source. A simplified block model comprises a debris field of collapsed sulphide chimneys (Black Smokers) over an alteration pipe which was the metal bearing fluid pathway. Classic examples have high temperature copper bearing minerals in the vent complex (stockwork / stringer zone) with lower temperature lead and zinc minerals being deposited along the flanks. In the BMC, there is also a large Fe component represented by both pyrite and more local Fe formations, the latter key to some of the discoveries.
The Green Revolution is bringing an increased demand for Cu, Pb, Zn, and Ag, in an already global shortage of these metals. The need for Copper wiring and battery metals is 40% of every electric car, and charging stations coming first to mind. Demand for both Lead (Pb) and Zinc (Zn) is exploding as battery development matures. Copper and silver are also key components of solar panels and wind turbines, due to their high conductivity. We all want to have an environmental friendly footprint and a reduction in fossil fuel usage, however the dilemma that faces us is that, with several countries stipulating new car sales to be 50% EV by 2030 & 100% by 2050, at the present time there is not enough supply of the required base metals to support that goal or even get close.
The opportunity for VMS exploration is very optimistic
With high-grade lead, zinc, copper, silver and gold in one single deposit, and with long mine life, VMS is very appealing to production mining companies.
Nine Mile Metals is very well positioned and actively pursuing the source deposit to our discovered VMS lens.
Born in 1952 with the discovery of the Brunswick 6 mine, the 1950’s were productive with 29 deposits discovered by leveraging the newest technologies available including airborne surveys and ground geophysical methods. As technology and analytical advancements were made, discoveries increased in the 1970’s and 1980’s with the application of low cost analytical and geophysical techniques. Regional studies from the mid 1990’s to 2000 included the camp wide EXTECH- II Project, which integrated multidiscipline data, including magnetics (Aerodat) and electro-magnetics (MegaTEM) into a GIS format leading to the discoveries of the Camelback, Mt. Fronsac North and Key Anacon East (Titan). From 2020 onward, advancements in data processing and particularly the analysis of geophysical data, including the Extech and Aerodat programs, is leading to the identification of high quality, priority targets not previously recognized in the legacy data.
Examples demonstrating the power of this new technology, taken from other project areas in the Bathurst Mining Camp, are shown below.
The next wave of discoveries will be with led by AI technologies and 3D modelling of data.
