Core Viewpoint - Nova Minerals Limited is reporting exceptional results from its ongoing RPM gold feasibility metallurgical test work program, indicating significant potential for gold recovery optimization [1][3][4] Group 1: Metallurgical Test Work Results - The metallurgical test work at the RPM Deposit shows the ability to achieve up to 68.7% gold recovery from lower-grade material through heap leaching [4][21] - A significant upgrade of 4.33 times was achieved using ore sorting technology, enhancing the feed grade for processing [4][11] - The multi-pronged approach combining ore sorting, heap leaching, and CIP/CIL processing is expected to maximize gold recovery and reduce processing costs [5][24] Group 2: Ore Sorting Technology - Particle density X-Ray Transmission (XRT) ore sorting technology has been successfully implemented, allowing for the separation of target minerals from waste [7][8] - The ore sorting process increases the mill feed grade and reduces energy requirements and tailings generation, leading to a more environmentally friendly operation [7][8] - The bulk test demonstrated that the RPM ore is amenable to ore sort upgrading, achieving a concentrate of 5.72 g/t Au from a 1.32 g/t feed [11][13] Group 3: Heap Leaching Process - Heap leaching is identified as a low-cost alternative for gold recovery from lower-grade ore, with the potential to recover gold from large volumes of material previously considered waste [15][16] - The heap leaching test work showed that gold extraction of 68.7% can be achieved from RPM low-grade ore after 59 days of leaching [21][22] - The process is noted for its simplicity and lower operating costs compared to conventional methods, facilitating quicker cash flow generation [26] Group 4: Project Development and Future Outlook - The results from the metallurgical test work strengthen the belief that the Estelle Project could become a world-class, long-life gold district [6] - Ongoing test work for CIP/CIL and HPGR crushing aims to further optimize the processing flowsheet and enhance economic outcomes [6][20][24] - The company is focused on advancing the Estelle Project, which encompasses multiple mining complexes in a region known for its significant gold endowment [29]
