Forsys has launched a broad-ranging initiative to reassess its 2015 Feasibility Study (“FS”) for its fully owned Norasa Project in Namibia. The Company sees potential to improve project economics by optimizing pit parameters and examining the potential of using heap leaching in mineral processing. The work program that began in mid 2023 and is anticipated to finish in mid 2024 includes the following components:
To achieve these objectives, the Company recruited a 27 person team who have significant previous uranium mining experience at variousNamibian operations. The technical team includes process engineers, mining experts, geologists, environment consultants, and local specialists led by the Company’s Namibian Country Director, Pine Van Wyk.
Further Drilling Program
Recent advancements in metallurgical, engineering and mining technology since exploration and computation of the Norasa Project’s FS have warranted a comprehensive review of the project. In mid 2023, the Company commenced a new 4,100 m drilling program to retrieve fresh samples at depths of up to 420 m from the slope areas for both the planned mining pits at Valencia and Namibplaas.
The drilling program focuses on:
Figure-1 below, illustrates the drilling program within ML-149 Valencia and EPL-3638 Namibplaas (ML-251 pending). Currently one Reverse Circulation (“RC”) drill rig and two Diamond Core (“DC”) drill rigs are on ML-149. Additional drill locations are planned for further in-depth studies and for geotechnical assessments.
By the end of October 2023, a total of 1,445 m of RC drilling and 1,865 m of DC drilling had been completed, including substantial large diameter metallurgical drilling at the Valencia, ML-149 site. Work is ongoing and the majority of the programme is targeted for completion by year end 2023.
Heap Leach Trade-Off Studies and Test Work
In March 2023, Forsys engaged DRA Projects Pty Ltd, a subsidiary of DRA Global Limited (ASX; DRA/JSE: DRA) (“DRA”) to oversee test work and conduct various engineering studies. The test work and studies aim to assess the potential trade-off opportunity between tank and heap leaching given advances in High Pressure Grinding Rolls crushing and heap leach technology.
Column leach tests are underway at SGS laboratories in South Africa, including measurements of ore height and slump in the column, with residues analyses for uranium content. The column leach tests results will inform heap leach recovery projections and key process conditions for the economic assessments. Final results of this trade-off study are expected first quarter 2024.
Mining Licences, Environmental Certificates and Permits
The Company currently holds a 25-year Mining Licence (ML-149) for its Valencia deposit, valid until 2033. Additionally, Forsys is actively engaged with the Ministry of Mines and Energy (MME) to renew its Exclusive Prospecting Licence (EPL-3638) for further pit optimization work at the Namibplaas site.
Earlier in the year, Forsys renewed its Environmental Clearance Certificate (“ECC”) from the Ministry of Environment, Forestry and Tourism for a further three-year term., allowing the Company to advance its development plans for the Norasa project. The ECC renewal process evaluated the Company’s environmental management practices, including waste management, emissions controls, biodiversity protection, and community engagement, among other factors.
Forsys is in the process also of securing additional permits, encompassing land surface rights; accessory works; radiation management; linear infrastructure development and desalination.
