CZR Resources Limited announced significant progress in its strategy to grow the target production rate and mine life at its Robe Mesa deposit in WA's Pilbara, with a further 20% increase in the JORC Resource to 45.2Mt at 56% Fe (62.7% Fe.ca). The increased tonnes were primarily from drilling of the northern extension, an area not previously drilled and outside of the Mineral Resource and 2020 Pre-Feasibility Study (PFS) pit designs. Drilling of the lower Channel Iron Deposit (CID) in the south of the Robe Mesa deposit also intersected thick mineralisation which contributed to the overall increase in tonnes. This updated Mineral Resource estimate represents the completion of drilling within the proposed mining footprint at Robe Mesa (Figure 1), a key milestone for the projects DFS. In addition, over 80% of the Mineral Resource estimate is categorised as Indicated (Figure 3), an important step in maximising the Resource to Reserve conversion in the Ore Reserve and mine plan update, now underway. The Robe Mesa deposit sits within CZR's Yarraloola Iron Ore Project (Figure 2), located 120km southwest of Karratha. The deposit strike length is 1.8km and is bounded to the south by the tenement boundary with Rio Tinto's Mesa F deposit and to the north with heritage restricted work areas. The deposit represents the track of a Tertiary-aged channel from the Robe River into older rocks of the Ashburton formation that have since eroded. A total of 94 reverse circulation (RC) drill holes were completed to a nominal 50m x 50m drill pattern. All RC drill-holes used a 5.5" (140mm) face-sampling percussion hammer, with 2-3kg of RC drill cuttings split over a static cone splitter during drilling and collected at 1 metre down hole intervals. All RC holes were drilled vertically, and downhole intervals are considered true width. Each metre of RC chips was described geologically for colour, texture and estimated mineralogical abundance. The volume of sample derived from each metre drilled was approximately equal and sample recovery was considered representative. Drilling has identified two intervals of flat-lying pisolitic iron-stone sediments that are each up to 25m thick and separated by up to 20m of shaley material. CZR geologists provided mineralisation and geological wireframes to Snowden Optiro, with separate high- and low-grade mineralisation domains. The lower-grade domain was defined by iron grades exceeding approximately 50% Fe and the higher-grade domain captures iron grades that largely exceed 53% Fe and are associated with silica (SiO2) grades less than 10%. The parent block dimensions are 25m x 25m x 4m, with sub-
blocking to 6.25m x 6.25m x 1.0m at domain boundaries.
