VANCOUVER, Canada, April 21, 2022 (GLOBE NEWSWIRE) -- Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) (“Sonoro” or the “Company”) is pleased to report assay results from an additional 15 drill holes completed as part of a drilling campaign currently underway at its Cerro Caliche gold project in Sonora, Mexico. As previously announced, the objective of the program is to increase the estimated size and grade of the project’s oxide gold mineralization as well as to potentially extend the estimated life of the proposed heap leach mining operation as outlined in the Preliminary Economic Assessment (PEA) filed in October 2021.
These latest results include drilling conducted at El Colorado and Guadalupe gold mineralized zones in the southwest of the concession’s mineralized zones where multiple high-grade gold intercepts were previously reported within larger intervals of higher-grade gold mineralization, as well as at El Bellotoso gold mineralized zone in the northeast region.
Highlights are as follows:
- SCR-289 intercepted 7.62m averaging 0.562 g/t Au; including 1.52m averaging 1.385 g/t Au
- SCR-292 intercepted 3.04m averaging 1.765 g/t Au; including 1.52m averaging 3.370 g/t Au
- SCR-293 intercepted 12.19m averaging 0.874 g/t Au; including 1.52m averaging 3.62 g/t Au;
and 6.10m averaging 0.922 g/t Au; including 1.53m averaging 2.22 g/t Au;
and 7.62m averaging 2.262 g/t Au; including 1.53m averaging 10.25 g/t Au
- SCR-295 intercepted 1.52m averaging 1.455 g/t Au; and 1.53m averaging 6.00 g/t Au
- SCR-296 intercepted 7.62m averaging 0.673 g/t Au; including 1.53m averaging 1.835 g/t Au;
and 6.10m averaging 0.422 g/t Au; including 1.52m averaging 1.00 g/t Au
- SCR-298 intercepted 3.05m averaging 0.884 g/t Au; including 1.53m averaging 1.455 g/t Au
- SCR-299 intercepted 10.67m averaging 9.018 g/t Au; including 6.10m averaging 15.558 g/t Au
- SCR-301 intercepted 10.67m averaging 0.497 g/t Au; including 1.52m averaging 1.795 g/t Au
Mel Herdrick, Sonoro’s VP Exploration noted, “With the discovery of multiple prospective high-grade ore-shoots identified by drilling at El Colorado, we are developing an understanding of the permissible extent and trend of these potential ore-shoots that may have up to seven additional repetitions in the footwall of the Guadalupe vein zone extendingup to 700 meters to the northwest of El Colorado. These high-grade ore-shoots may add significantly to the existing resource. The process of defining these zones also allows us to refine our understanding of the structural geology and, consequently, identify additional areas for possible material resource expansion and a recalculation of the existing resource.”
Kenneth MacLeod, Sonoro’s CEO and President commented, “We continue to be very pleased with the results from our Phase IV drilling program which is expected to be completed by early May with the remaining results expected at the end of May. While we move forward with the development of the proposed mining operations, we will now begin assessing the potential economic impact of the new geological data on the project.”
John Darch, Sonoro's Chairman commented, "We are very encouragedwith thelatest drilling results.The extension of several gold mineralized zones as well as the multiple deeper higher-grade intercepts suggests the drilling program may meet its objective ofincreasingthe size and grade of the resourceand therefore potentially extend the life of our proposed mining operation as well as improve the overall economics of the project. This is a very exciting time for Sonoro and its shareholders.”

El Colorado Zone
On March 1, 2022, the Company announcedthat drill hole SCR-286 had intercepted high-grade gold mineralization at the deepest level of El Colorado’s epithermal system drilled to date. Eight drill holeswere recently completed at El Colorado to expand mineralization near this intercept,including drill hole SCR-289 which intercepted 7.62meters averaging 0.562 g/t Au, including 1.52meters averaging 1.385 g/t Au. Drill hole SCR-290 was drilled at a 60-degree inclination following strike and is located below SCR-286 where it intercepted 3.05 meters averaging 0.378 g/t Au.In close proximity, SCR-292 intercepted 3.04meters averaging 1.765 g/t Au, including 1.52meters averaging 3.370 g/t Au.
Vertical drill hole SCR-298 intercepted 3.05 meters averaging 0.884 g/t Au, including 1.53 meters averaging 1.455 g/t Au and drill hole SCR-299 intercepted 4.58 meters averaging 0.497 g/t Au and 10.67 meters averaging 9.01 g/t Au, including 6.10 meters averaging 15.558 g/t Au located at depth of 64.01 meters and approximately 50 meters northwest of SCR-286.
Vertical drill hole SCR-300 intercepted 3.04 meters averaging 0.407 g/t Au, near the projected intercept area where gold is anomalous with high values of lead and zinc. A lost interval at 117 meters showed high manganese oxide content with no sample and high-water flow suggesting a post mineral fault which may displace the mineralization.
Two drill holeswere also completed outside of the resource pit shell used to calculate the zone’s gold resource in the updated Mineral Resource Estimate.Drill hole SCR-291 is approximately 100 meters southeast of the proposed pit shell where it intercepted 3.05 meters averaging 0.530 g/t Au, including 1.53 meters averaging 1.670 g/t Au. Drill hole SCR-293 is approximately 30 meters eastof the pit shell where it intercepted 12.19metersfrom surface averaging 0.874 g/t Au, including 1.52meters averaging 3.62 g/t Au.At a depth of 184.4 meters, the same drill hole intercepted 7.62meters averaging 2.262 g/t Au, including 1.53meters averaging 10.25 g/t Au.

Guadalupe Zone
At the Guadalupe zone, four drill holes were collared on the western side of the proposed resource pit cone for calculating the zone’s gold resource as outlined in the updated Mineral Resource Estimate. Drill hole SCR-294 intercepted 3.05 meters averaging 0.525 g/t Au at a depth of 121.92 meters and drill hole SCR-295 intercepted 1.52 meters averaging 1.455 g/t Au at a depth of 112.78 meters and intercepted another 1.53 meters averaging 6.00 g/t Au at a depth of 164.59 meters.
Intervals in drill holes SCR-296 and SCR-297 show extensions of the gold mineralization along the southeastern trend and drill hole SCR-294 contained short intervals representing stockwork type mineralization but the average grades reported are below the PEA resource cutoff for inclusion.
El Bellotoso Zone
In the northeast region of the property, drilling at El Bellotoso intercepted gold mineralization, extending the zone 200 meters along strike. Four drill holes were completed with drill holeSCR-301returning the best results. SCR-301 was collared at the southeastern side of the proposed El Rincón pit cone and intercepted 10.67meters averaging 0.497 g/t Au from near surface, including 1.52 meters averaging 1.795 g/t Au.

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.

The Company cautions that forward-looking statements are based on the beliefs, estimates and opinions of the Company's management on the date the statements are made and they involve a number of risks and uncertainties, including the possibility of unfavorable exploration and test results, the lack of sufficient future financing to carry out exploration and development plans and unanticipated changes in the legal, regulatory and permitting requirements for the Company’s exploration programs. There can be no assurance that such statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking statements. The Company disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law or the policies of the TSX Venture Exchange.
