This is from another site as per Reiner:
We have an update out today on progress regarding our PFS on the near-surface gold-in-oxide mineralization at our Cuiu Cuiu project in Brazil. This is an exciting time for our company as we advance the PFS on the viability of mining the near surface gold-in-oxide material and heap leach processing of that material. If the PFS is positive, it should allow for a construction decision during mid-2024. Here are Alan’s thoughts. Principle takeaways: 1. We are making good progress with the PFS. The current RC drill program is a significant part of this effort and is aimed at identifying additional higher-grade mineralization. We have completed 69 RC holes to date as part of this program and results are currently pending on 55 holes, so expect more drill results in the near future 2. This drilling program has returned some excellent higher-grade results to date. These will be incorporated in a revised resource estimate of the oxide material, which in turn will be incorporated into the mine plan. These positive drill results may result in additional higher-grade material which needs to be assessed for gold recoveries 3. As a result, additional column leach metallurgical tests are planned as we consider optimizing throughput rates, pad heights etc. for the heap leach operation. This additional metallurgical work will require a little more time and the PFS is now likely to be completed during the second quarter of 2024 4. A second drill rig has arrived on site and is drilling. This second rig is in the process of completing a geotechnical program aimed at understanding the overall ground conditions prior to the erection of the heap leach pads, the agglomeration and ADR plants, and associated infrastructure. The rig has also been tasked with collecting additional samples for the metallurgical work 5. OK – so what does this all mean? Well, it means that the drill results received thus far have been very positive and are leading to abit of a rethink on several issues including throughput rates – this means the PFS continues to evolve and is generating opportunities to optimize the value of the project which will take abit more time We will not have definitive answers on the economic viability of mining and processing the near surface oxide material until Q2 2024 but there will be a lot of news between now and then – obviously if the PFS study is positive, it will be a very significant step forward As a reminder, the trial mining and heap leach operation is a stepping stone aimed at providing the Company with sufficient capital to drill 1/. The gaps in the existing resources at the MG and Central gold deposits, 2/. Calculate maiden resources for the PDM and Machichie deposits and 3/. Determine how many of the +45 targets are additional gold deposits
