Global Mining Review,
Cavalier Resources has announced that initial intermittent bottle roll testing on coarse oxide reverse circulation drill chips from the Crawford Gold mineral resource is now complete. Testing focused on mineralised oxide material currently contained within the resource at Crawford. The portion of Indicated oxide comprises approximately 61% of the current JORC Mineral Resource Estimate (MRE) (at a 0.5g/t cut-off). Test work returned an average gold recovery of 85% from a broad representative set of samples, with a peak recovery of 93.2% for sample CRC04. The company has now commenced the next phase of heap leach focused metallurgical studies, starting column leach, agglomeration, and percolation test work which will provide valuable insights into the heap leaching process and its effectiveness for the Crawford Gold Project.
Highlights
- Initial bottle roll tests on coarse reverse circulation (RC) oxide drill chips from Crawford complete.
- Excellent results returned with a peak sample gold recovery of 93.2% (CRC04).
- Average gold recovery of 85% over six representative samples.
- Mineralised oxide portion of the resource appears very fine and may require minimal crushing.
- Column heap leach work has commenced with associated agglomeration and percolation testing.
- Heap leach experts Kappes, Cassiday & Associates Australia continue to assist managing studies.
Daniel Tuffin, Executive Technical Director, commented: "We have completed the initial bottle roll tests on coarse reverse circulation (RC) oxide drill chips from the Crawford Gold Project. The results are highly encouraging and pave the way for the next phase of heap leach studies for the project. Tests focused specifically on the oxide material within the gold resource area at Crawford, which currently constitutes approximately 61% of the Indicated oxide portion of the resource. We are thrilled to announce an average gold recovery of 85% across a highly representative sample range. An impressive peak sample gold recovery rate of 93.2% was returned, further highlighting the early-stage potential to heap leach oxides at Crawford. Of particular significance is the observation that the mineralised oxide portion of the resource appears to be very fine and may therefore require minimal crushing. This characteristic suggests potential cost efficiencies and streamlined processing methods, which in addition to expected low mining costs could further positively impact our operational timelines and project economics. In line with our commitment to advancing the project, we have initiated column heap leach work, which includes agglomeration and percolation testing. These critical next steps in our metallurgical studies will provide valuable insight into the effectiveness of heap leaching gold at the Crawford Gold Project. Cavalier's strategic direction for the area remains focused on establishing sustainable cash flows and fully unlocking the potential of our assets in Leonora. We are committed to prioritising initiatives that contribute to long-term financial success, utilising our resources and expertise strategically. Our continued goal is to create a robust, self-reliant, and self-sustaining presence in the Leonora area, capitalising on the opportunities available to us.”
