Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA:
23SP) (“Sonoro” or the “Company”) is pleased to report assay
results from an additional seven drill holes completed at its Cerro
Caliche gold project in Sonora, Mexico. Results reflect recent
drilling activity conducted at two of the property’s gold
mineralized zones, El Colorado and El Rincón, with the reported
intercepts situated outside of the pit shells used to calculate the
mineral resource estimate announced in September 2021 as part of a
Preliminary Economic Assessment (“PEA”) for a proposed heap leach
mining operation.
Highlights are as follows:
- SCR-305 intercepted 36.5m averaging
0.54 g/t Au; including 1.53m averaging 3.59 g/t Au; including 1.53m
averaging 3.32 g/t Au.
- SCR-307 intercepted 9.14m averaging
9.58 g/t Au; including 6.09m averaging 14.17 g/t Au; including
1.52m averaging 38.3 g/t Au.
- SCR-309 intercepted 6.10m averaging
1.37 g/t Au; including 1.53 averaging 3.97 g/t Au.
The map below illustrates the location of the
drill holes.

The drilling campaign at Cerro Caliche is now
complete with final assays expected to be announced in June. New
geological data from over 7,200 meters and 63 drill holes will be
included in a further updated resource estimate scheduled to be
released in the fall 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 VP Exploration,
commented, "We continue to report good gold bearing intervals of
mineralization as well as higher-grades intercepts that continue to
add to potential mineralized material. Results from another 15
drill holes are still pending and we are working to determine the
structural controls of the new higher-grade zones."
Kenneth MacLeod, Sonoro’s President and CEO,
commented, “Our continued success with demonstrating high-grade
intercepts at the Colorado zone suggests the potential for an
increase in both the grade and size of the gold resource at El
Colorado. Additional success at the Rincon zone through infill
drilling has also achieved our objective of identifying continuous
mineralization between two pit shells located 400 meters apart,
suggesting the potential for coalescing the pit shells into one
larger pit shell.”
John Darch, Sonoro's Chairman, noted, “The
expansion of the El Colorado and El Rincón gold mineralized zones,
along with the multiple higher-grade intercepts we have announced
during the Phase IV drilling program, adds to our optimism that
this new geological data may potentially increase both the size and
gold grade of the resource. If confirmed, an expanded resource may
also improve the project’s potential economics and extend the mine
life of the proposed mining operation.”
El Colorado
Gold Mineralized
ZoneContinued expansion of El Colorado was
confirmed with four drill holes completed along the western side of
the zone. The shallow, high-grade intercepts of drill hole SCR-307
returned 9.14 meters averaging 9.577 grams of gold per tonne (“g/t
Au”) including 6.09 meters averaging 14.167 g/t Au and 1.52 meters
averaging 38.3 g/t Au. SCR-307 does not correlate with any known
projected vein and may be part of a series of high-grade ore shoots
connected to deeper high-grade occurrences in the footwall of the
Guadalupe vein structure, believed to be a continuation of El
Colorado vein system as discussed in the Company’s News Release
dated March 1, 2022.
The Company is also investigating a possible
physical connection of SCR-307 to SCR-036 which, as previously
announced, intercepted 1.52 meters averaging 11.45 g/t Au. These
structures which appear near horizontal in attitude, contain higher
gold grades with low silver levels and lead levels exceeding one
percent. It is believed that the ore shoots are a repeating series
of veins developed in a reverse fault episode which opened
horizontal structures in the footwall of the Guadalupe Vein zone
allowing higher-grade fluids to deposit gold and lead. Assay
results from five holes at El Colorado are pending.
The geology of the El Colorado mineralized zone
is complex with a mixture of silicified meta-sedimentary units
intruded by a silicified and argillic altered quartz porphyry
igneous body and, in deeper parts, granodiorite with dioritic to
andesitic dikes. The mineralized structures trending north 10 west
and dipping northeasterly cross the zone extending southerly from
the Cabeza Blanca quartz veins. As many as five high-grade ore
shoots intersect the Guadalupe footwall and the zone contains
numerous additional veins and veinlets that are situated apart from
the above-described vein zones.

El
RincónApproximately two kilometers north of El
Colorado, six drill holes were completed along the northwest
trending El Rincón structure between two separate pit shells used
to calculate the September 2021 mineral resource estimate. These
pit shells are approximately 400 meters apart with continuation of
mineralization between the pit shells confirmed by a total of 16
drill holes, over approximately one kilometer of strike length.
Drill holes SCR-301 through SCR-306 were infill drilling completed
during the current program.
Results from drill holes SCR-301, SRC-302 and
SCR-303 were announced on April 21, 2022, and drill holes SCR-304,
SCR-305 and SCR-306 are detailed in the table below. Highlights
include drill hole SCR-304 which intercepted 1.52 meters averaging
2.49 g/t Au and drill hole SCR-305 which intercepted 36.5 meters,
averaging 0.535 g/t Au, including 1.53 meters averaging 3.59 g/t Au
and 1.53 meters averaging 3.32 g/t Au.
The structure's trend is azimuth 310 with dip of
85 northwest to vertical. This vein structure cuts both rhyolitic
dikes and sills and bedded meta-sedimentary rocks with gold silver
mineralization occurring in both rock types. The El Rincón vein
zones are generally parallel to, or along, the rhyolite dike
margins.

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 DescriptionCerro
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.

(NI 43-101) and has read and approved this news release. Readers
are cautioned that the presence of mineralization on historic mines
adjacent to or on Cerro Caliche is not necessarily indicative of
economic gold mineralization in the concessions held by the
