Sonoro GOLD Reports Higher-Grade Intercepts and Expands GOLD Mineralization at Cerro Caliche GOLD Project
SONORO GOLD REPORTS HIGHER-GRADE INTERCEPTS AND EXPANDS GOLD
MINERALIZATION AT CERRO CALICHE GOLD PROJECT
VANCOUVER, Canada, May 25, 2022 – Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP)
(“Sonoro” or the “Company”) pleased to report assay results from an additional 10 drill holes completed
at its Cerro Caliche gold project in Sonora, Mexico. Results reflect drilling conducted at El Colorado and
Buena Suerte gold mineralized zones where intercepts include 1.52 meters averaging 9.57 grams of gold
per tonne (“g/t Au”), 28.95 meters averaging 1.021 g/t Au and 10.67 meters averaging 1.183 g/t Au. As
with drilling results announced on May 17, 2022, current intercepts are also situated outside of the pit
shells used to calculate the mineral resource estimate as part of an updated Preliminary Economic
Assessment (“PEA”) announced May 9, 2022, for a proposed heap leach mining operation.
Highlights are as follows:
• SCR-313 intercepted 21.34m averaging 0.557 g/t Au, including 3.04m averaging 1.523 g/t Au
• SCR-314 intercepted 3.05m averaging 1.185 g/t Au, including 1.52m averaging 2.19 g/t Au;
and 7.62m averaging 0.72 g/t Au, including 1.53m averaging 1.635.
• SCR-315 intercepted 10.67m averaging 1.183 g/t Au, including 1.52m averaging 3.27 g/t Au;
and 4.57m averaging 1.087 g/t Au, including 1.53m averaging 2.28 g/t Au.
• SCR-318 intercepted 1.52m averaging 9.57 g/t Au and 28.95m averaging 1.021 g/t Au;
including 1.53m averaging 2.07 g/t Au, including 3.05m averaging 2.706 g/t Au
The map below illustrates the location of the drill holes.

Results from seven additional drill holes completed at the Abejas gold mineralized zone are still pending
and will be announced next month, concluding the Phase IV drilling program at Cerro Caliche. Geological
data from this latest drilling campaign will be included in a further updated resource estimate scheduled
to be announced in the summer of 2022. The updated technical report will also assess the potential
economic impact of the new drilling data on the proposed heap leach mining operation.
Mel Herdrick, Sonoro's Vice President of Exploration, noted that “I continue to be encouraged by the
results of the Phase IV drilling campaign which has returned multiple higher-grade intercepts and
demonstrated resource growth potential near surface and at depth. These latest assay intercepts also
indicate continued expansion of El Colorado and Buena Suerte mineralized gold zones outside of the pit
shells used to calculate the resource estimate for the initial PEA. The potential expansion will be confirmed
in an updated resource estimate expected to be completed over the next few months.”
Kenneth MacLeod, Sonoro’s President and CEO stated, “With the updated mineral resource estimation
potentially demonstrating an increase in multiple gold mineralized zones at Cerro Caliche, we are now
reviewing the additional work involved to incorporate the new data into an updated technical report on
the proposed mining operation. This has been a successful drilling campaign and I look forward to sharing
the final drilling results with our shareholders.”
John Darch, Sonoro’s Chairman, added, “I am very pleased with the latest results as they indicate a
potential increase in both the size and grade of the of the project’s oxide gold mineralization. As announced
when drilling resumed in November 2021, the objective of this drilling program was to expand the resource
and potentially improve the economics and mine life of the proposed heap leach operation. We are
becoming more optimistic that we may meet this objective.”
El Colorado Gold Mineralized Zone
Five drill holes were completed at El Colorado extending mineralization approximately 30-meters along
the northwestern side of the estimated resource pit shell. Shallow gold mineralization was cut in all five
drill holes with drill holes SCR-313, SCR-314 and SCR-315 returning multiple higher-grade intercepts.
Drill hole SCR-315 tested for a possible extension of the mineralization contained within the northernmost
extent of the pit shell and beginning at 7.62 meters, it intercepted 10.67 meters averaging 1.183 g/t Au,
including 1.52 meters averaging 3.27 g/t Au and 4.57 meters averaging 1.087 g/t Au, including 1.53 meters
averaging 2.28 g/t Au.
Approximately 50 meters northwest of the previously reported drill hole SCR-307, which intercepted 9.14
meters of 9.577 g/t Au, drill hole SCR-313 tested the outside perimeter of the pit shell, intercepting 21.34
meters of 0.557 g/t Au, including 3.04 meters of 1.523 g/t Au.

Buena Suerte Vein System
Located approximately 300 meters east of El Colorado, five drill holes extended the Buena Suerte vein
system to the southwest with drill holes SCR-318, SCR-319 and SCR-320 located immediately outside the
resource pit shell boundary.
Drill hole SCR-318 cut strong gold mineralization intercepting 1.52 meters averaging 9.57 g/t Au and 28.95
meters averaging 1.021 g/t Au, including 1.53 meters averaging 2.07 g/t Au, as well as 3.05 meters
averaging 2.706 g/t Au. Drill hole SCR-320 intercepted 4.57 meters averaging 0.851 g/t Au, including 1.53
meters averaging 2.11 g/t Au.
Drill holes SCR-316 and SCR-317 are located further south with assay results of only short uneconomic
intervals, possibly due to an unmapped fault having shifted vein extensions to other positions.

Quality Assurance/Quality Control ( “QA/QC”) Measures and Analytical Procedures
Drill samples are collected with an airstream cyclone and passed into a splitter that divides each sample
into quarters. The quartered samples are then bagged and sealed with identification. The sample group
has blanks, standards and duplicates inserted into the sample stream.
ALS-Chemex collects the samples and transports them directly to the preparation laboratory in
Hermosillo, Sonora. At the laboratory, part of each sample is reduced through crushing, splitting and
pulverization from which 200 grams is sent to the ALS-Chemex assay laboratory in Vancouver. Thirty
grams undergoes fire assay for gold with the resulting concentrated button of material produced is
dissolved in acids and the gold is determined by atomic absorption. Another quantity of the sample is
dissolved in four acids for an ICP multi-element analysis.
No QA/QC issues were noted with the results received from the laboratory.
Geologic Description
Cerro Caliche is located 45 kilometers east southeast of Magdalena de Kino in the Cucurpe-Sonora Mega-
district of Sonora, Mexico. Multiple historic underground mines were developed in the concession
including Cabeza Blanca, Los Cuervos, Japoneses, Las Abejas, Boluditos, El Colorado, Veta de Oro and
Espanola. Mineralization types of the Cucurpe-Sonora Mega-district include variants of epithermal low
sulfidation veins and related mineralized dikes and associated volcanic domes. Local altered and
mineralized felsic dikes cut the mineralized meta-sedimentary rock units and may be associated with
mineralization both in the dikes and meta-sedimentary rocks.
