Kenneth MacLeod, President & CEO of Sonoro, commented: “The current phase of the drill program is focused on expanding mineralized zones and upgrading the resource classification at the four main zones that Micon International will assess in the updated 43-101 technical report currently being prepared. At the same time, drilling is also addressing the potential pit optimization that might be achieved by combining the conceptual Japoneses and Buena Suerte open pits into one larger pit. The 43-101 technical report will incorporate all the drilling conducted to the end of March 2021 and is anticipated to be completed early in the third quarter of 2021.”

John Darch, Chairman of Sonoro, also noted: “The continued expansion of the Buena Suerte Gold Zone and the positive drilling results at El Rincón and the newly identified Bellotoso zone brings us closer to our goal of developing a major bulk-tonnage, oxide gold resource with the potential to provide a source of production and revenue in the years to come. At the same time drilling at the Japoneses zone is making an essential contribution to the project’s conceptual plan, to be addressed in a 2021 PEA, to develop a heap leach mine operation having an initial capacity of up to 20,000 tonnes per day.”

Buena Suerte shows a 200-meter-long High-grade Zone in the Northwest Extension   
Drilling at the northern extension of Buena Suerte demonstrated a 200-meter-long high-grade ore zone, suggesting the presence of an ore shoot, in the vicinity of holes SCR-109, SCR-186, SCR-148 and SCR-098. Hole SCR-186 is approximately 50-meters north of SCR-109 which, as previously reported, intercepted 45.72 meters averaging 0.97 g/t Au starting at three-meters below surface, including a high-grade section of 15.24 meters averaging 2.101 g/t Au.

Assay highlights include:

• SCR-186 intercepted 24.39 m averaging 1.206 g/t Au, including 13.72 m averaging 1.853 g/t Au.
• SCR-187 intercepted 9.14 m averaging 0.522 g/t Au and 21.9 g/t Ag.
• SCR-191 intercepted 16.77 m averaging 0.451 g/t Au and 3.04 m averaging 0.409 g/t Au.
• SCR-194 intercepted 9.14 m averaging 0.466 g/t Au and 27.3 g/t Ag.

Drill hole SCR-195, the most northwesterly hole drilled to date at Buena Suerte, intercepted 6.09 meters averaging 0.466 g/t Au beginning at three-meters from surface. The drill hole is a 50-meter step-out from previous drilling and additional drilling is planned to test further continuity of the northwest extension.

Japoneses Zone Drilling
At Japoneses, drilling has identified numerous mineralized intersections along the full extent of the zone’s western boundary where future pit optimization may be achieved between the potential convergence of the conceptual Japoneses and Buena Suerte open pits.

Assay highlights include:

• SCR-198 intercepted 19.81 m averaging 0.465 g/t Au from surface.
• SCR-197 intercepted 7.62 m averaging 0.513 g/t Au from 9.14 meters.
• SCR 188 intercepted 6.10 m averaging 0.560 g/t Au from surface.
  

Most notably, drill hole SCR-198 intercepted 19.81 meters averaging 0.465 g/t Au from surface, while approximately 50 meters to the south, drill hole SCR-197 intercepted 7.62 meters averaging 0.513 g/t Au from 9.14 meters below surface. Numerous additional RC drill holes have been completed along the western flank of Japoneses and pending assay results are expected to contribute further to the mineralization of the zone.

Mel Herdrick, VP of Exploration, commented, “Our drilling to define the 500-meter-long west side of Japoneses ridge is an important component of the upcoming PEA, as the most recent results increase the potential that we may combine the conceptual Japoneses and Buena Suerte pits into a single pit. It is very encouraging that drilling identified a 200-meter-long high-grade ore zone at the northern extension of Buena Suerte, while also expanding the size of the mineralized gold zones at Veta de Oro, El Rincon and Bellotoso zones.”

El Rincón, Veta De Oro, Bellotoso, and Gloria Exploration Drilling
The El Rincón vein area was further tested with two RC drill holes. Drill hole SCR-174 cut an approximately 70-meter section of anomalous gold beginning at surface, where a 10.67-meter intercept averaging 0.308 g/t Au was cut between 45.72 meters to 56.39 meters. Drill hole SCR-175 cut a similarly broad anomalous interval and, beginning at 3 meters, intercepted 3.05 meters averaging 0.836 g/t Au. The drill holes are the furthest northwest step outs in the Rincon zone and are within the vein trend which remains open to the northwest following outcropping quartz veins.

At Veta de Oro, drill hole SCD-045 intercepted 5.1 meters averaging 0.367 g/t Au and 4.5 meters averaging 0.327 g/t Au. SCD-045 was completed to test the vein’s northwest extension along trend towards the El Rincon vein zone and is situated 250 meters southeast of drill hole SCD-021 at the El Rincon zone which intercepted 21 meters averaging 1.13 g/t AuEq. SCD-045 is a substantial step out, further confirming the continuity of the mineralization at the El Rincón – Veta de Oro – Abejas Zone. Sonoro’s geological team will be reviewing in detail the data set regarding vein characteristics, mineralogy, and metal zonation in relation to Cerro Caliche’s evolving low sulfidation epithermal model, to determine the best sections for future drilling of this promising area.

The Bellotoso vein zone drilling consisted of four core drill holes and two RC holes. The best interval from these holes is from core hole SCD-044 which intercepted 10.5 meters averaging 0.86 g/t AuEq. The other 3 core holes are located in the far northwest part of the Bellotoso vein trend and include SCD-047 which is a step-out to a secondary parallel vein zone. The Bellotoso strike is parallel to El Rincon and is separated in part by a rhyolitic dike that appears to be source of the gold bearing fluids that mineralized the local area.

At Gloria, five exploration holes were drilled approximately 500 meters northwest of Buena Suerte, in an area with historical artisanal gold workings.   Drill hole SCR-179 intercepted 7.62 meters averaging 0.182 g/t Au and SCR-181 intercepted 1.52 meters averaging 1.47 g/t Au. The remaining holes contained minor intervals with low gold content without any significant gold bearing zones. The Gloria zone will be further assessed to determine its prospectively further to the northwest, where previous drilling demonstrated more consistent mineralization.

The low-grade intercepts indicate drilling cut deeper than the ‘ideal’ low sulfidation epithermal boiling zone. This observation is supported by low gold to silver ratios with low silver content as illustrated by the only anomalous interval from drill hole SCR-181 (from 22.86 to 24.38 meters) of 1.47 g/t Au and 0.15 g/t Ag illustrates. This mineralization is typical of deeper intersections at or just below the base of epithermal vein boiling zone.

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.

Bureau Veritas (BV) 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. About 200 grams are sent by BV to their Vancouver, Canada laboratory and dissolved in aqua regia for multi-element ICP analysis, including silver. Of these samples, 30 grams undergo fire assay in Hermosillo for gold by reducing the fire assay to a concentrated button of material that is dissolved in acids and the gold content determined by atomic absorption.

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 felsic dikes cut the mineralized meta-sedimentary rock units and may be associated with mineralization both in the dikes and meta-sedimentary rocks.

Host rocks include Jurassic-Cretaceous meta-sedimentary rock units including argillite, shale, quartzite, limestone, quartz pebble conglomerate and andesite. Younger intrusive rock consisting of medium coarse-grained granodiorite-granite is present in the westerly parts of the concessions near the historic Cabeza Blanca Mine. It is apparent that veining cuts and pervasively alters the intrusive stock. Rhyolite occurs in irregular bodies distributed in higher elevations in the northerly part of the concession, including the Rincon area, where it occurs as flows, sills, dikes and rhyolite domes. Part of the rhyolite is mineralized and appears to be related to epithermal gold mineralization throughout the property.
