Tocvan Announces
Geophysical Survey Results Indicating Several New T argets at the Pilar Gold-Silver Project in Sonora, Mexico
Calgary, Alberta – May 20, 2020. Tocvan Ventures Corp. (CSE: “TOC”) (“ Tocvan ” or the “ Corporation ”) is pleased to announce
initial results from the detailed geophysical survey at the Pilar Gold-Silver Project in Sonora, Mexico.
Detailed Induced Polarization ("IP") geophysical su rveys were completed by TMC Exploracion Geophysics in two perpendicular line
directions at 75 metre line spacing to reveal detai led subsurface features. Initial results are presen ted here, and the data will be further
processed and integrated with geological and geoche mical data for further interpretation.
The IP survey was conducted over an area with the m ost historic information, in particular the northwe st section of the property with
17,700+m of drilling. This was strategically planne d and executed in order to calibrate the geophysica l results with known geology,
drill data, physical properties measurements on kno wn mineralization and alteration. This has revealed new mineralization targets,
extensions to known mineralization zones, and the c ontinuity of geological trends. This analysis just ifies the pursuit of targets in the
surveyed area and allows for the calibrated geophysical model to be applied on the second half of the property.
Note that this geophysical survey is the first in a series of techniques (see press release March 31, 2020) to develop a greater
understanding of the mineralized structures, in ord er to have greater accuracy in locating drill targe ts for the late summer to early fall
drill program. Objectives have been achieved, see below.
Resistivity Low is Key:
The dark purple and light purple areas shown in the 3D IP Inversions (Figure 1) are resistivity lows. These areas can reflect alteration,
specifically mineral-replacement with oxide such as hematite.
Chargeability Low is Key:
The green and blue areas shown in Figure 2 are char geability lows. These areas can represent alteratio n, specifically mineral-
replacement with some oxide such as hematite.
Previous workers and the due-diligence conducted on the property by Mark Smethurst report hematization in these areas, hematization
at Pilar is associated with gold & silver mineraliz ation. This is corroborated with drilling results i n these areas that show high grade
gold and silver returns over significant intervals as reported in press releases of previous operators . Note that the resistivity lows are
continuous suggesting a connection between the Nort h Hill Zone with the Main Zone as well as with the 4-Trench Zone. Note the
correlation between the chargeability low with the resistivity low.

The following three figures show 3D-inversion proce ssing of the IP data in order to reveal detail from surface to a depth of ~100m.
These figures show a N-S striking chargeability low and a resistivity low that are coincident with eac h other. Almost all of the drill
holes are located in these lows and gold & silver m ineralization have been recorded in these lows. Epi thermal gold-silver
mineralization forms along structures, the minerali zation is characterized by hematite, which is known to reside in structures along
with gold & silver. The resistivity and chargeabili ty lows can indicate structure and alteration, spec ifically mineral-replacement with
some oxide such as hematite. This calibrated geoph ysical model can be applied to the remaining part o f the property to the east where
high grade gold and silver assay results were recov ered during due-diligence showing a second parallel mineralized zone (see press
release Jan. 7, 2020).
The Main Zone and North Hill Zone are possibly conn ected in which case these would be renamed as a min eralization trend. There is
the possibility of two feeder-pipe-like features or possible chutes. Results also indicate the possibi lity of NE-SW structures connecting
the 4-Trench Zone to the Main Zone. Resistivity ind icates the continuation of the NNW-SSE trend of the historically drilled
mineralization and these results open up the opport unity to develop mineralized areas:
1. Between the North Hill Zone and the Main Zone,
2. Between the 4-Trench zone and the Main Zone,
3. Extending southward from the Main Zone,
4. Within the new second parallel zone to the east,
5. Extending downward beneath the feeder-pipe-like features.

The geophysical results will be combined with addit ional survey tools to help create a structural mine ralization model to identify drill
targets for the Phase 2 campaign. As mentioned in t he press release of March 31, 2020 those surveys ar e close-spaced soil sampling
which has been effective in providing directional t rends of mineralization; structural geology surveys from a specialist structural
geologist; and XRF survey of samples across the pro perty and of historic drill hole samples held in st orage, the XRF will collect data
to identify elements and their amounts and will ass ist in identifying alteration minerals and pathfind er elements, knowing the intensity
of alteration minerals and their location will help to define linear mineralized structural features t hat contain gold and silver.
Results from these surveys will be combined with pr e-existing data from historic drill holes and the a ssayed gold and silver results
from those holes will be included as part of the co llected data to identify the structural features th at contain the gold-silver
mineralization.
Special Note:
The current world health situation requires adjustments to work programs, health and safety is considered first.
Current health advice is for families and groups to self-isolate and to use caution with suggested rec ommendations from health leaders
when social-distancing becomes a challenge. Countri es are beginning to allow businesses to operate aga in. Isolation is an inherent part
of mineral development programs.
About the Pilar Property
The Pilar Gold-Silver property has been identified as a structurally controlled low-sulphidation epith ermal project hosted in Andesite
and Rhyolite rocks. Hydrothermal fluids carrying go ld, silver and other minerals are transported throu gh the pre-existing structures
and deposit out of the fluids and become emplaced w ithin the structures and surrounding host rock. Thr ee zones of mineralization
have been identified in the north-west part of the property from historic surface work and drilling an d are referred to as the Main Zone,
North Hill and 4 Trench. Structural features and zo nes of mineralization within the structures follow an overall NW-SE trend of
mineralization. Over 17,700m of drilling have been completed to date. Significant results are highligh ted below from previous
operators:
• 17,700m of Core & RC drilling. Highlights include (all lengths are drilled thicknesses ):
- 6 -
o 0.73g/t Au over 40m
o 0.75g/t Au over 61m
o 17.3g/t Au over 1.5m
o 5.27g/t Au over 3m
o 53.47g/t Au & 53.4g/t Ag over 16m
o 9.64g/t Au over 13m
o 10.6g/t Au & 37.8g/t Ag over 9m
• 2,650m of surface and trench channel sampling. Highlights include:
o 55g/t Au over 3m
o 28.6g/t Au over 6m
o 3.39 g/t Au over 50m
• Soil sampling results from undrilled areas indicati ng mineralization extends towards the southeast fro m the Main
Zone, North Hill Zone, and 4-Trench Zone
Additional areas of mineralization have been identi fied resulting from surface rock-grab-sample assay results that extend known
mineralized trends and show a second NW-SE trend of mineralization to the east parallel to the trendin g zone described above; gold-
silver mineralization is indicated across the prope rty from the north to the south, see press release dated January 7, 2020. Significant
results from that particular survey are highlighted below:
