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.
The key access negotiations and environmental and technical studies are well advanced.
Robe Mesa is a quality asset, with ore reserves of 8.2Mt at 56.0% Fe with a total resource of 84.5Mt at 53.8% Fe (to JORC 2012 standards).
The deposit consists of two sub-horizontal sheets of pisolitic ironstone that each improve in quality and grade upwards and it’s the near surface part of the upper sheet that hosts the ore-reserve.
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.
