Tocvan Reports: (August 30th, 2022)
Seven drill holes were completed, totalling 1,382-meters. Results for the final four drill holes are highlighted in this release. All four drill holes were drilled in new areas and intersected alteration and structures known to host gold-silver mineralization at Pilar. Hole JES-22-72, 125-meters southeast of drill hole JES-22-63 (13.7m of 0.6 g/t Au and 13 g/t Ag and 9.2m of 0.6 g/t Au) returned 22.9-meters of 0.3 g/t Au and 19 g/t Ag, including 7.6-meters of 0.8 g/t Au and 51 g/t Ag (Figure 1) Three drill holes intersected low-grade gold and silver values indicating close proximity to significant mineralization. Hole JES-22-70 returned 12.2-meters of 0.3 g/t Au, including 3.1-meters of 0.8 g/t Au and 3.1-meters of 0.5 g/t Au. Hole JES-22-69 intersected 1.5-meters of 0.7 g/t Au at the end of hole, leaving it open at depth for targeting. The Company is extremely encouraged by these reconaissaince results and planning is underway for the next stage of drilling at Pilar.

"With each progressive stage of reconnaissance drilling along previously untested trends we are uncovering excellent indications that mineralization continues to the southeast and in parallel trends to our Main Zone," commented CEO, Brodie Sutherland. "All seven drill holes intersected alteration, quartz-veining and fault structures know to host significant mineralization at Pilar. All three trends tested during this stage of drilling have shown indications of continued mineralization and warrant follow-up drilling as we believe a much larger system is yet to be defined at Pilar."
Discussion of Results
As part of the ongoing Phase III drill program, a total of seven reverse circulation ("RC") drill holes have been completed, totalling 1,382-meters. Drilling focused on the 4-T Expansion and Extension targets and a new trend discovered during the last stage of drilling (Figure 1 and Table 1).
JES-22-69
This drill hole was targeting the 4-T Extension, where surface sampling of artisanal workings returned 6.6 g/t Au and 433 g/t Ag. Four quartz-sericite veins with pyrite were intersected at 10.7 to 30.5-meters, 82.4 to 86.9-meters, 157.1 to 158.6-meters and 173.9 to 176.9-meters. Low-grade gold mineralization was intersected from surface to 16.8-meters depth. A 1.5-meter interval of 0.7 g/t Au was recorded at the end of the hole with coincident elevated arsenic values (>1500 ppm) which suggest mineralization is open at depth. Follow-up targeting up and down-dip of this drill hole is warranted to test continuation of mineralization.
JES-22-70
This drill hole was targeting the 4-T Trend, 80-meters southeast of where a recent surface trench (T-21-2) returned 19.5-meters of 0.6 g/t Au. Three quartz-sericite veins with pyrite were intersected at 58.0 to 63.0-meters, 132.7 to 143.8-meters, and 163.2 to 164.7-meters. From surface, JES-22-70 returned 12.2-meters of 0.3 g/t Au including, 3.1-meters of 0.8 g/t Au and 3.1-meters of 0.5 g/t Au. Low-grade gold and zinc were recorded further down hole from 77.8-meters (3.1-meters of 0.4 g/t Au and 1.82% Zn). The 4-T Trend remains larger untested down-dip at depth, the indications of mineralization and structure recorded warrant further follow-up of the trend for broad, higher-grade intervals.
JES-22-71
This drill hole was targeting the Discovery Trend, 115-meters southeast of JES-22-72 (see below). Quartz-sericite veins with pyrite were intersected from surface to 36.0-meters, 90.0 to 95.0-meters, 108.7 to 112.9-meters and 154.0 to 158.6-meters. Low-grade silver and zinc were recoded from surface to 6.1-meters (6 g/t Ag and 0.1% Zn). Although no significant mineralization was recorded the structure and alteration intersected indicate potential for significant mineralization continues along this trend.
JES-22-72
This drill hole was targeting the newly identified Discovery Trend, 125-meters southeast of drill hole JES-22-63 which returned, 54.9-meters of 0.3 g/t Au and 5 g/t Ag including, 13.7-meters of 0.6 g/t Au and 13 g/t Ag and 9.2-meters of 0.6 g/t Au). Drill hole JES-22-72 returned 22.9-meters of 0.3 g/t Au and 19 g/t Ag or 0.5 g/t AuEq including, 7.6-meters of 0.8 g/t Au and 51 g/t Ag or 1.3 g/t AuEq. Zinc values are elevated across the upper half of the drill hole with high concentrations (1.97% Zn over 7.6-meters) associated with high Au-Ag values. Quartz-sericite veins with pyrite were intersected at 9.2 to 15.0-meters, 91.5 to 100.7-meters and 120.5 to 129.7-meters. The highest-grade mineralization is hosted with in a silicified andesite with quartz veinlets and moderate iron-oxide alteration. Both JES-22-63 and JES-22-72 remain untested down-dip, mineralization and structure seen in JES-22-71 indicates the system has room to expand further to the southeast. The discovery trend remains open to the northwest.

About the Pilar Property
The Pilar Gold-Silver property is interpreted as a structurally controlled low-sulphidation epithermal system hosted in andesite rocks. Three zones of mineralization have been identified in the north-west part of the property from historic surface work and drilling and are referred to as the Main Zone, North Hill and 4-T. Structural features and zones of mineralization within the structures follow an overall NW-SE trend of mineralization. Over 22,000 m of drilling has been completed to date.

Quality Assurance / Quality Control
RC chips and core samples were shipped for sample preparation to ALS Limited in Hermosillo, Sonora, Mexico and for analysis at the ALS laboratory in North Vancouver. The ALS Hermosillo and North Vancouver facilities are ISO 9001 and ISO/IEC 17025 certified. Gold was analyzed using 50-gram nominal weight fire assay with atomic absorption spectroscopy finish. Over limits for gold (>10 g/t), were analyzed using fire assay with a gravimetric finish. Silver and other elements were analyzed using a four-acid digestion with an ICP finish. Over limit analyses for silver (>100 g/t) were re-assayed using an ore-grade four-acid digestion with ICP-AES finish. Control samples comprising certified reference samples and blank samples were systematically inserted into the sample stream and analyzed as part of the Company's robust quality assurance / quality control protocol.
