300-meters of Strike Tested with First Phase of Drilling, confirms exploration model of at and near-surface oxide gold mineralization connected to underground workings
"We are extremely pleased with the results of this first program at El Picacho where we have not only confirmed mineralization tied to the old workings but also stepped-out and discovered even better mineralization at depth," stated Brodie Sutherland, CEO. "We now have a better understanding on the optimal drill orientation to test the system and look forward to following-up on not only the San Ramon prospect but testing the other prospects across the large land package. To be able to test our model, adjust on the fly and use this information to successfully hit the best mineralization in our first step-out is a massive testament to the team. We look forward to analyzing these results to plan for the next stage of drilling at El Picacho."

Discussion
The drill program was successful in identifying mineralization in three target areas: Las Guijas, San Ramon and the newly discovered extension to San Ramon. Initial review of the data suggest drilling in a southeast direction (azimuth 120) provides the best result for testing high-grade mineralization and adjacent low-grade. Hole SRA-22-010 has proven the model of a west-dipping package of altered and mineralized quartz veins and shear zones exist and appear to continue at depth and remain open to the west and south of the known area. A detailed account of the key drill holes is provided below.
SRA-22-010 - Azimuth 120, Dip -45o, Total Depth 180.0m
This hole targeted a 100-meter step-out on trend and down-dip of known mineralization projected from the San Ramon underground workings. From surface to 45.8-meters depth a moderately oxidized zone within gneiss was intersected with two 3-meters zones of veining and pyrite, although altered no significant mineralization was recorded in this upper zone. At 45.8-meters a fault was encountered transitioning into a vein zone to 58.0-meters. This vein zone hosts the majority of high-grade gold mineralization averaging 2.0 g/t Au over 12.2-meters, with values up to 14.2 g/t Au. Below the vein zone anomalous mineralization (Au and Ag) continues until 90.0-meters depth where it then breaks up into several anomalous zones before transitioning to a weakly altered/ oxidized diorite at 164.7-meters. Through the vein zone anomalous Au, Ag, As, Sb and Pb are recorded averaging 2.0 g/t Au, 7 g/t Ag, 246 ppm As, 168 ppm Sb and 381 ppb Pb.
SRA-22-008 - Azimuth 115, Dip -65o, Total Depth 151.0m
This hole targeted the area adjacent and underneath the San Ramon underground workings. A weakly oxidized diorite was recorded from surface to 12.2-meters depth transitioning into a silicified diorite and vein zone until 45.8-meters depth. The vein zone returned the strongest mineralization from 21.4-meters to 38.1-meters returning 16.8-meters of 0.5 g/t Au, including 4.6-meters of 1.8 g/t Au and 6 g/t Ag. Anomalous pathfinder elements (As, Sb, Pb and Zn) were recorded through the vein zone. Alteration weakens at 54.9-meters depth. At 79.3-meters the gneiss unit was encountered until 122.0-meters depth were the lithology changed to a metasediment unit for the remainder of the hole. Anomalous Ag, W and Cu were recorded in the lower metasediment unit.
SRA-22-005 - Azimuth 130, Dip -45o, Total Depth 100.7m
This hole targeted the area adjacent and underneath the San Ramon underground workings at its eastern-most extent. A weakly oxidized diorite was recorded from surface to 18.3-meters before coming into an oxidized vein zone from 18.3-meters to 36.6-meters. The vein zone returned anomalous Au, Ag, As, Ab, W, Pb and Zn with Au values up to 1.0 g/t and Ag values up to 18.3 g/t. Below the vein zone a weakly altered diorite was recorded to 79.3-meters where a felsic dyke was encountered until 91.5-meters followed by the metasedimentary unit until the end of hole.
The remaining holes all hit anomalous mineralization and veining with elevated path finder elements while testing different orientations. Although no significant mineralization was recorded the technical team views this as a great indicator of a robust mineralized system. Hole SRA-22-004 intersected a vein zone from 18.3-meters to 29.0-meters with elevated Au, Ag, As, Sb and Zn. A lower metasediment unit returned elevated Ag and As nearly over the entire length, recording 2 g/t Ag over 100.6-meters. Hole SRA-22-006 intersected a section of discontinuous veins before encountering an underground void at 27.5-meters. Hole SRA-22-007 also hit an underground void just after entering a vein zone from 21.4-meters depth with Au values up to 1.0 g/t and Ag values up to 54 g/t. Hole SRA-22-009 recorded a vein zone from 13.7-meters to 36.6-meters with anomalous Au, Ag, As, Sb, W, Pb and Zn.
About the El Picacho Property
The El Picacho Gold-Silver property is interpreted as an orogenic gold system within the regional Caborca Orogenic Gold Belt known for producing gold mines that include La Herradura (>10 Moz Au) and San Francisco (>3 Moz Au). The project is 140 kilometers north of Hermosillo and only 18 kilometers southwest of the producing San Francisco Mine. The Project totals 24 square kilometers. Five primary zones of mineralization have been identified across the property totalling over six kilometers of prospective trends. Surface sampling and historic workings have identified high-grade gold and silver values. The project has only seen widely spaced reconnaissance drilling with no follow-up. Tocvan believes this provide an excellent opportunity for discovery of a muti-million ounce district.

About the Pilar Property
The Pilar Gold-Silver property has recently 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. Three primary 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. The Main Zone and 4-T trends are open to the southeast and new parallel zones have been recently 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. To date, over 22,000 m of drilling has been completed.
