Peninsula Energy Limited to Provide an Update on the MU1A Low-pH Field Demonstration at its 100% Owned Lance Project (‘Lance’) in Wyoming, USA

05/16/2021 | 06:27pm EST

Peninsula Energy Limited (‘Peninsula’ or ‘the Company’) to provide an update on the MU1A low-pH field demonstration at the Company's 100% owned Lance Project (‘Lance’) located in Wyoming, USA. The field demonstration of low-pH In-Situ Recovery (‘ISR’) has been flexibly designed to generate comprehensive site-specific data on the influence of certain development and operational parameters ahead of a final investment decision to restart production at the Project. Since the last field demonstration update, actions have been taken across key focus areas to ensure performance continues to meet the Company's expectations. Further changes to the configuration of the injection and recovery well patterns have been implemented with the intention of reducing response times for assessing and adjusting chemical parameters. The Company has also commenced the evaluation of several alternative uranium recovery process options with the object of reducing downstream processing costs. Achieving and maintaining the correct operational pH and Oxygen Reduction Potential (‘ORP’) for the process solutions is critical to successful uranium low-pH ISR operations. As reported on 13 April, changes in oxidant and pattern configurations delivered significant improvement in key chemical parameters. The demonstration operations have continued over the last month without significant disruption. With the original pattern configuration having longer than typical distances between injection and recovery wells, more than one month of operations is generally necessary to observe the impacts of operational adjustments. The pH of each recovery well has continued moving modestly downward toward the target level during the last month. Free acid concentrations, another measure of acidity, have improved in 2 out of the three recovery wells. At approximately 400 mv, the recovery stream ORP has also moved closer to the target range of 450 to 600 mv during the past month. After a doubling of uranium grade to between 20 and 25 ppm as reported on 13 April, the grade has remained within this range during the past month. As noted in the 13 April update, the Company has adjusted the original pattern configuration of 10 injection wells fully surrounding 3 recovery wells by installing and activating two new internal injection wells that are located between each pair of recovery wells. To further reduce the expected response time for chemical parameter adjustments, the Company has subsequently switched off selected perimeter injection wells that were more distant to the recovery wells, creating a pattern design with the average injector to recovery well distance reduced from 135 feet to approximately 80 feet. These supplementary pattern configuration changes should accelerate the upward movement of uranium grades. As previously reported, with increasing field demonstration grades, the Company activated the pilot ion exchange uranium recovery circuit in early March. Within the current range of uranium concentrations, ion exchange systems have limited capacity to capture and retain uranium, and minimal actual recovery of uranium has occurred thus far. Ion exchange processes are concentration driven and the system performance is expected to improve with increasing uranium grades. Mindful of the widely understood limitations of ion exchange processes in low pH applications, including those at successfully operating commercial facilities, the Company has identified and begun evaluating several innovative uranium recovery process flowsheet options. The alternative process technologies are being evaluated progressively with desktop, benchtop and potentially pilot scale demonstrations that can be run in conjunction with the current field demonstration. These advanced technologies have the potential to significantly enhance downstream processing performance while reducing operating costs. Peninsula will provide further updates on the MU1A low-pH field demonstration as additional meaningful results become available.
