PRESS RELEASE
Tocvan Diagnostic Leach Study Reports High Percentage of Recoverable Gold and Silver
Highlights
• Diagnostic Leach Study Reports High-Percentage of Recoverable Gold and Silver (Au: 95 to 99%; Ag: 73 to 97%)
• Head Screen Assays Report High-Grade Gold and Silver (2.7 to 24.9 g/t Au and 8.8 to 74.2 g/t Ag)
• Gravity Concentrate Assays for Gold and Silver range from 35.6 to 290.3 g/t Au and 53 to 1,152 g/t Ag
• Majority of Gold and Silver can be Recovered with Gravity Concentration and Agitated Cyanide Leach
• Drill core sample indicates same recovery potential at depth (150m down hole) as at surface.

Calgary, Alberta – April 11 , 2023 – Tocvan Ventures Corp. (the “Company”) (CSE: TOC; OTCQB: TCVNF ; FSE : TV3),
is pleased to provide the results of a Precious Metal Diagnostic Leach Study from its Pilar Gold-Silver Project in Sonora,
Mexico. Five composite samples were collected for the study; three Mai n Zone surface channel composites ( samples
494741, 494743 and 494745) ; one 4 -T surface channel composite (sample 494747); and one drill core coarse reject
composite (sample 494749) from drill hole JES-22-62 at 150-meter downhole depth, 125-meters from surface (108.6m of
0.8 g/t Au, including 9.5m of 7.6 g/t Au). Table 1 summarizes the findings of the report and highlights the total recoverable
amount of gold and silver possible by gravity concentration followed by agitated cyanide leach of the gravity tails. Precious
metal characterization for each sample is summarized in Table 2, highlighted by a large percentage of free gold and si lver
with the remaining portion predominantly “exposed but attached”, indicating a large percentage of the gold and silver can
be recovered. The study was completed by independent and ISO certified, metallurgical lab LTM, a full report of the study
is available on the Company’s website.
"These results far surpass our expectations and provide us with new insight on the optimization of gold and silver recovery
at Pilar” stated Brodie Sutherland, CEO. “ To have such a large percentage of the gold and silver free and accessible for
multiple recovery methods allows us to ev aluate the most efficient ways to develop the project . This is a huge checkmark
for the project and an excellent indicator to the industry that Pilar can be developed. We look forward to further evaluating
the bulk sample data in the coming months.”

About the Bulk Sample
Over 1,400 tonnes of oxide-gold material have been extracted from select areas exposed at surface across the project area,
focusing on the Main Zone and 4 -T Trends where preliminary column leach studies have returned promising head -grade
and recovery results. Bulk Sample material will be prepared for processing by heap -leach method at a private mining
operation less than 25 kilometers to the west of Pilar. Information from the sample will aim to provide a more detailed
account of expected head-grade and recovery percentage of gold along with providing key information to optimize future
production facilities. The information provided from the sample will be used for planning in coordination for permitting of
full-scale mine and process facilities on-site at Pilar.

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 a nd 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 exten ds along a 1.2 -km trend, only half of that trend has been
drill tested so far. To date, over 23,000 m of drilling has been completed.

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 of area showing similarities in geology and structure as the San Francisco Mine . 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. Recently the Company completed its first
drill program at El Picacho, confirming its model and hitting significant gold mineralization In a step-out to historic workings.
Drill hole SRA-22-010, intersected 44.2-meters of 0.6 g/t Au, including 12.2-meters of 2.0 g/t Au and 7 g/t Ag. As
exploration and drilling continues, Tocvan believe s this provide an excellent opportunity for discovery of a muti -million
ounce district.
