Figure 1. Summary map of recent surface sampling, expanding the known footprint of mineralization of the Greater Pilar System. The sampling has identified the source rocks for the active placer mining operations. Sampling and mapping have also outlined a significant area of veining and epithermal style alteration with elevated Au, Ag, As, Sb, Pb and Zn. The area has seen no previous systematic exploration and remains open to the east and the north. Direct extension of the Pilar Main Zone is also apparent through past sampling.
"This is an incredible discovery expanding out a significant mineralized footprint in an area with no previous exploration." commented Brodie Sutherland, CEO. "Placer activity has provided the most concrete evidence for new mineralized systems, and this is the first step in beginning to fully understand the potential size for a much larger system at Pilar. The experience we have from operating at Pilar has allowed us to move quickly to evaluate these areas. For the first pass sampling to return these results is a testament to the team and the gold-silver endowment seen across the project. This vastly expands our resource potential across the Greater Pilar property that we have
Discussion of Results
Placer Source Discovery
Over the past three years placer mining by local workers have ramped up activities in the Pilar area, most notably just north of Pilar where workings now extend 3.5 kilometers up a dry creek bed. Placer miners have focused on loose unconsolidated material that can easily be extracted and screened with an excavator. Most operations consist of one excavator operator and three 20 tonne haulage trucks used to transport material to a nearby sluice box for quick gravity recovery of the gold. The placer activity has provided an obvious vectoring tool towards areas potentially shedding gold from larger source rocks. Through geological mapping and sampling above these placer activities, the Company has quickly been able to pinpoint the primary source for the placer gold. An area 800 meters by 700 meters has been identified as the source zone with the highest-grade samples collected so far adjacent to new road development and placer activities. Mineralization is described as hosted in quartz veins, silicified hydrothermal breccias and faults associated with altered andesite host rocks similar to those mapped at the Main Zone. Sample highlights include 5.5 g/t Au with 80 g/t Ag on trend with artisanal mine workings and shafts. The Company looks to further evaluate mineralization along these trends with the areas to the north and east remaining open to further gold-silver potential.
Expansion of Mineralized Footprint East of Main Zone
Further south of the newly outlined Placer Source Area mineralization continues with significant gold and silver values ranging up to 7.3 g/t Au and 389 g/t Ag. The total area evaluated in the first pass of mapping and sampling covered 800 meters by 800 meters and remains open to the east for another 1,600 meters. Mineralization is primarily associated with quartz veining and related alteration (sericite, silica and iron oxides).
Extension of Main Zone
Past surface sampling of the northern extension of the Main Zone onto the newly acquired expansion area have shown gold values above 10 g/t Au (historically no overlimit was tested) and silver values up to 645 g/t Ag (Sample 617771, collected by Tocvan in 2021). These samples indicate multiple mineralized trends extend onto the expansion area for at least another 200 to 300 meters before plunging below overburden. These trends have full road access and will be evaluated in exploration drilling planned for later in 2024.

Pilar Project Planview map showing the southern block made up of the Pilar Main Zone and the newly discovered placer source with additional gold-silver mineralization extending to the south. Within the northern block, a large alteration zone that spans 3.3 km by 1.5 km (North Alteration Zone) has returned high-grade gold and silver values in the first few sampling programs across the newly acquired area. The initial phase of drilling for 2024 will focus on the Pilar Main Zone in which Tocvan has

An additional 67 samples were collected along new road cuts developed by local placer miners.
About the Pilar Property
The Pilar Gold-Silver property has returned some of the regions best drill results. Coupled with encouraging gold and silver recovery results from metallurgical test work, Pilar is primed to be a potential near-term producer. Pilar is interpreted as a structurally controlled low-sulphidation epithermal system hosted in andesite rocks. Initially three primary zones of mineralization were identified on the original property from historic surface work and drilling and are referred to as the Main Zone, North Hill and 4-T. Each trend remains open to the southeast and north and new parallel zones have been discovered. Structural features and zones of mineralization within the structures follow an overall NW-SE trend of mineralization. Mineralization extends along a 1.2-km trend, only half of that trend has been drill tested so far. The Company has now expanded its interest in the area by consolidating 22 square-kilometers of highly prospective ground where it has already made significant surface discoveries.
