SEDEX Deposits: Right Economics to Supply Global Zinc Demand Fireweed Zinc believes that by using a newly deposit model, that being of metal-rich brines having formed shale-hosted zinc deposits below the seafloor by the replacement of barite, and not necessarily in rocks that were deposited in a deep marine setting, new deposits may be detected by broad geochemical halos in the hanging wall.
As well in 2018, Fireweed Zinc will focus their step-out and infill drilling by vectoring back towards the high-grade material that formed around the feeder zones to not only increase the confidence of the resource, but also its size.
In addition, the company is planning an aggressive mapping and sampling program for 2018, supported by high-quality geophysical surveys. This data will be used to model the architecture of the basin to identify key structural-stratigraphic SEDEX targets for future drilling. Plenty of future catalysts to look forward to in 2018, with perhaps the biggest being an economic study that shows the market a project that can deliver high margins, icing on the cake would be discovery of new SEDEX deposits, and a little luck.
