TriStar Gold Inc. provide an update on advancements in environmental permitting activities toward requesting the Liçença Previa (Preliminary Licence or LP) for the Castelo de Sonhos gold project in Pará state Brazil. TriStar has also initiated metallurgical test work as part of a value engineering study on the prefeasibility design process facility at Castelo de Sonhos. Metallurgical testing has been initiated on a composite sample from Esperança South, which is the source of plant feed for the Pre-Feasibility Study (PFS) projected phase one of operations, where gold production is approximately 150,000 ounces per year. The intent is to evaluate the impact of changing leach feed grind size on plant throughput, leach residence time and metallurgical recovery. Results will be coupled with value engineering studies to optimize the preliminary design concepts contained in the recent PFS, providing the basis for ongoing plant development. Previous test work showed that at a 105-micron grind size eight samples averaged 98% recovery (with three of the eight having no detectable gold in the tails sample), which was used as the basis for the PFS metallurgical recovery assumptions. Additional test work conducted at a grind size of 150 microns averaged 96% recovery across four composite samples. The new metallurgical program is designed to aid understanding of the relationship between grind size of 105 microns up to 250 microns and metallurgical recovery. TriStar report that work on the Environmental Impact Assessment and Environmental Impact Report (EIA) for the Castelo de Sonhos gold project in Pará State, Brazil has significantly advanced. All activities are being conducted in strict accordance with the Terms of Reference for the EIA issued in March 2020 by the Environmental Licensing Directorate of the Secretariat of Environment and Sustainability (SEMAS) for Pará State. The Terms of Reference lay out specifications, guidelines and expectations for the content and final presentation of the EIA. The EIA will culminate in the application for the Preliminary License (LP), which will indicate the government's conditional approval of the environmental viability of the project. The LP is the first of three environmental licenses to be acquired in advance of mine commissioning, the other two being the Construction License (LI) and the Operation License (LO). TriStar anticipates making the formal request for the LP in Second Quarter of 2022. The EIA is a collaboration between TriStar, Brazilian regulators, and various environmental and socio-economic consultants, with SETE Ambiental of Belo Horizonte overseeing preparation of the EIA. Groundwater and surface water monitoring as well as hydrogeological modeling are being performed by Water Services & Technologies in close coordination with SETE. Air, noise & vibration monitoring as well as speleological (caving) studies have also been undertaken as part of the EIA. TriStar report that all significant baseline data collection is now complete. In strict accordance with the Terms of Reference as well as all applicable national and state regulations, the seasonal collection of data relating to flora and fauna, ground & surface water, air, noise & vibration, socio-economic aspects of the area, caves, archeology & paleontology is finished. A forest inventory has been completed, and with the recent completion of the PFS, TriStar's EIA team is excited to move from baseline data collection into impacts analysis and mitigation.
