Castile Resources Limited presented the new Mineral Resource Estimate (MRE) for Rover 1 that has been updated to include the two new discoveries from targeting extensions to gold and copper mineralisation in the Jupiter Deeps region of Rover 1. The Company recently announced a new high grade gold zone discovery and also confirmed a significant extension to the mineralised Jupiter Deeps IOCG alteration. The 2022 program was true "exploration" style drilling aimed at growing the Resource inventory by targeting extensions to the existing gold and copper mineralisation that lies down dip of the Jupiter Deeps region of the Rover 1 orebody. Analysis is now complete on all sampling collected from the Rover 1 2022 exploration drilling campaign and Castile to announced that the total metal inventory of gold, copper, cobalt and magnetite have all increased significantly primarily due to large increases in the Inferred category representing extensions to the Jupiter Deeps ore body.

Compared to the MRE released on 8 March 2022, increases in the new September 2022 MRE include: Total gold increased by 20% to 315,200oz with Inferred gold increasing by 289% to 81,400oz. Total copper increased by 7% to 83,200t with Inferred copper increasing by 44% to 20,100t· Total cobalt increased by 5% to 4,000t with Inferred cobalt increasing by 22% to 1,100t. Total magnetite increased by 18% to 1,295,000t with Inferred magnetite increasing by 119% to 357,000t.· Total tonnage increased by 18% to 5.58Mt with Inferred Tonnes increasing by 86% to 1.61Mt.

The Company was primarily targeting gold with this program so the majority of the additional tonnes are within the new high grade gold zones which typically carries less accompanying copper. This has seen the total universal copper grade decrease by 9% to 1.49% but the additional tonnes have seen total copper metal increase by 7% to 83,200t. A significant increase of 834,000t has taken the total tonnage of the MRE to 5,581,000t.

The big move is in grade and tonnages for the inferred section of the additional 52,000oz of gold. The inferred tonnes have increased by 86% to 1.61Mt but more importantly the gold grade has more than doubled from 0.75g/t to 1.57g/t, an increase of 110%. A significant amount of this inferred material will be added to mining inventory within the Pre-Feasibility Study which is now well progressed.
