VANCOUVER, British Columbia, March 11, 2021 (GLOBE NEWSWIRE) -- Sonoro Gold Corp.(TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) (“Sonoro” or the “Company”) is pleased to report the latest assay results from its ongoing drilling program at the Company’s Cerro Caliche gold project in Sonora, Mexico. The new results reflect 32 drill holes, totaling 2,830 meters and highlight the following:
Confirmation of a 200-meter-long, high-grade zone in the northwest extension of Buena SuerteHigh-grade intercepts at the northern extension of Buena Suerte including SCR-186 which intercepted 24.39 meters averaging 1.206 g/t Au, including 13.72 meters averaging 1.853 g/t AuFurther confirmation of continuous mineralization at the two kilometer long El Rincón - Veta de Oro - Abejas vein and stockwork gold mineralized zone.Further extension to the new Bellotoso gold mineralized zone through step-out drilling.

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 DrillingAt 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 19.8 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.
