Arizona Sonoran Copper Company Reports Impressive Extraction Rates
Arizona Sonoran Copper Company Inc. (TSX:ASCU | OTCQX:ASCUF) has announced notable advancements in its metallurgical testing program, demonstrating an average soluble copper extraction rate of 87% from enriched materials at the Cactus Project. This extraction achievement was the result of testing conducted on 12 leach columns, reflecting the company's commitment to optimizing recovery rates.
Significant Results from Metallurgical Testing
The company's metallurgical testing involved 12 leach columns, with the results showing strong performance over an extended 180-day leaching period. The six oxide and enriched composite columns from the Parks/Salyer deposit yielded an impressive soluble copper extraction rate of 87%, while another set of six columns focused on the final Stockpile achieved an average rate of 86% over a shorter 100-day period. This positive data bodes well for Arizona Sonoran’s future operational strategies.
Enhanced Copper Extraction Comparison
Comparing these results to historical extraction rates, which indicated 92% for oxide and 85% for enriched materials, the latest data supports the planned single pad leach approach outlined in the upcoming 2024 Preliminary Economic Assessment (2024 PEA). The favorable performance hints at the robust methodologies implemented into their leaching processes.
Investment in Future Development
Ahead of the anticipated 2025 Prefeasibility Study (2025 PFS), Arizona Sonoran has committed $3 million towards enhancing its metallurgical program. This investment aims to refine the Parks/Salyer deposit’s metallurgical information through a comprehensive work plan that includes 5 enriched columns, 2 enriched-oxide composites, and 4 primary sulphide columns. The strategy here is to focus specifically on heap leaching methodologies.
Collaboration with Experienced Labs
The metallurgical program is being undertaken by leading laboratories, Base Met and McClelland Labs, under the expert supervision of Steve Dixon, the Chief Engineer at Arizona Sonoran. This collaboration ensures that the testing protocols adhere to the best industry practices and benchmarks.
Core of the Testing Program
Each of the 12 leach columns stood at 20 feet and was meticulously designed to evaluate different material types, including enriched and oxide composites from the Parks/Salyer deposit. The remarkable extraction results observed are crucial for predicting the performance of future leach pads.
Introduction to Advanced Concepts
The term “heap efficiency factor” refers to the correlation between column test results and real operational performance. Operations that adhere to best practices are expected to achieve an efficiency factor close to 95%, which may enhance the total soluble copper recovery. Such measures could greatly impact future yield calculations.
Future Testing Plans
Looking ahead, the next round of testing aims to deepen the understanding of leaching dynamics, focusing on thermal contrasts and other influences on mineral extraction rates. New columns planned for testing will prioritize data collection from the Parks/Salyer deposit and the Cactus West area, driving the project’s development forward.
Commitment to Quality and Reporting
All technical aspects related to the ongoing metallurgical study have been scrutinized and validated by qualified professionals in compliance with relevant disclosure standards. This approach is designed to ensure transparency and accuracy in reporting the evolving findings. As a company, Arizona Sonoran aims to maintain the highest level of integrity in its disclosures and operational standards.
