The Robe Mesa deposit is CZR’s cornerstone project: a low strip ratio, low capex Direct Shipping Ore (DSO), with a rapid, low-cost path to production.
All Native Title agreements are in place with the Robe River Kuruma Traditional owners, mining licences are granted and environmental and technical studies are nearing completion.
Robe Mesa is a quality asset, with Ore Reserves of 27.3Mt at 55.5% Fe (62.2% Fe calcined) with a Resource base of 45.2Mt at 56% Fe (62.7% Fe calcined).
The iron-ore in the Robe Mesa is from the centre of the Robe palaeo-channel which contains a well-characterised and well-known pisolitic ore-type.
The ore has low phosphorous and upgrades well by driving off, or calcining, the volatile components, principally water. Discussions with potential clients indicate that the product is readily accepted as a DSO.
Following completion of a Pre-Feasibility Study in 2020 that outlined a project with robust economics, a Definitive Feasibility Study and process for approvals is now underway.
The definitive feasibility study is looking at optimization of the proposed scale of mining, haulage route, shipping location and capital spending as upsides to the PFS results.
