Sonoro Gold Corp


VANCOUVER, Canada, January 19, 2021 Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) (“Sonoro” or the “Company”) is pleased to report the remaining assay results from its 2020 drilling campaign at the Cerro Caliche gold project in Sonora, Mexico.  The 2021 drilling program is currently underway with approximately 50 additional RC and core holes expected to be completed by the end of the first quarter.  The latest assays further support the Company’s consideration of the viability for a bulk mining heap-leach development proposal with a conceptual throughput of up to 20,000 tonnes per day (tpd).

El Colorado Zone Enlarged

At the El Colorado gold mineralized zone, located in the southwestern region of the concession, four core holes were drilled to test the periphery of the zone’s intensely drilled higher grade gold shoots where drill holes announced December 18, 2020 include:


___•   SCR-044 intercepted 12.19 m averaging 11.22 g/t Au, including 6.09 m averaging 21.58 g/t Au

___•   SCD-008 intercepted 11.7 m averaging 0.92 g/t Au, including 4.55 m averaging 1.84 g/t Au


Three of the four new holes successfully tested the southeastern and northwest periphery of the higher-grade shoots:


___•   SCD-026 intercepted 8.4 m averaging 0.718 g/t Au

___•   SCD-027 intercepted 7.2 m averaging 0.601 g/t Au

___•   SCD-028 intercepted 6.0 m averaging 0.885 g/t Au


At the southeastern periphery, SCD-027 extended the shoots lengths by approximately 50 meters whereas at the shoot’s northern periphery, SCD-028 intercepted three different mineralized intervals. SCD-028 is located approximately 30 meters north of where previously announced drill hole SCD-016 also intercepted several mineralized intervals including 11.25 meters averaging 1.08 g/t Au.  Furthermore, the SCD-028 intercepts appear to be the western splay of the adjacent Guadalupe or Cabeza Blanca vein systems.  Another drill hole, SCD-025, tested the eastern edge of the higher-grade gold shoot and intercepted two short, mineralized intervals.

Guadalupe Zone

At the Guadalupe gold mineralized zone, located in the western region of the concession, scout drill hole SCD-029 intercepted 3.9 meters averaging 0.358 g/t Au, including 3.9 meters averaging 0.234 g/t Au.  The drill hole investigates the northernmost area of the Guadalupe zone and is approximately 250 meters north of the previously announced SCR-030 which intercepted 22.86 meters averaging 0.725 g/t Au.  Additional drill holes are planned to determine the potential for Guadalupe to increase the project’s gold mineralization.

Cabeza Blanca Zone Continues to Grow

At the Cabeza Blanca gold mineralization zone, located directly north of the El Colorado zone, core holes SCD-030 and SCD-031 confirm the zone’s extension more than 50 meters to the north:


___•   SCD-030 intercepted 9.3 m averaging 0.719 g/t Au

___•   SCD-031 intercepted 15 m averaging 0.503 g/t Au

Veta de Oro – Abejas Zone

At the southeastern end of the Veta de Oro gold mineralized zone, four core drill holes, SCD‑032, SCD‑033, SCD‑034 and SCD-035, and two RC holes, SCR-156 and SCR-157, tested an area of vein stockwork and confirmed narrowing vein zone in the covered area between the Veta de Oro zone and the Abejas zone, located 500 meters to the south.


SCD-032 through SCD-035 were the final core drill holes of 2020 and are located directly south of drill hole SCD-015 which, as announced on December 8, 2020, intercepted 16.25 meters averaging 0.741 g/t AuEq, including 3.0 meters averaging 2.11 g/t AuEq. Management believes these drill holes establish the potential for a higher-grade zone of gold mineralization to extend to the north approximately one kilometer to El Rincon. In addition, the Company built roads and drill pads in preparation for the drilling to test the north striking zone between El Rincon and Veta de Oro.  Drilling at this very high potential zone is currently under way with results expected by the end of February.


Table of Selected Core Drill Results: El Colorado, Guadalupe, and Cabeza Blanca

True widths in the El Colorado holes have yet to be established, while the Guadalupe intersections are considered true widths. Cabeza Blanca drill holes true widths are considered to be about 90% of reported drill length intervals.

Veta de Oro drill intersections are considered to be near true width drill intersections to reported drill length intersection lengths.

Japoneses Zone Infill Drilling

The following assay results are the final six of 33 RC holes drilled during the 2020 drill program.  A total of 70 holes have been drilled within the Japoneses zone (which now includes Boluditos and Chinos NW zones) as the Company works to define the 1,300 meter long by 400 meter wide zone’s shallow oxide gold mineralization.  These holes are intended to infill gaps in the drill pattern.  Selected RC drill hole Intercepts from the Japoneses mineralized zone include SCR-151 with 27 meters averaging 0.694 g/t Au which is a wide addition to the zone’s near surface mineralization.  A high-grade vein with a width of 3.05 meters averaging 3.355 g/t Au, which was intercepted within the 27-meter interval, is interpreted to be a section of the main Japoneses vein.  Intersections in the Japoneses zone appear to have true widths approximately 15 percent less than reported as drill length intersections.

Mel Herdrick, Sonoro’s VP of Exploration, commented, “The focused drill program of 2020 was very successful in further outlining additional gold mineralization, part of which contains significantly higher gold grades.  We have a substantial amount of additional drilling planned to fully define the project’s considerable potential.  Our plan is to drill up to 50 more holes as part of this effort by the end of March of this year, which we expect will be in time to contribute further to the updated resource estimate to be prepared by Micon International.”


Kenneth MacLeod, Sonoro’s President and CEO, added, “I am very happy to report at the conclusion of the 2020 drilling program that the program’s goals, as they relate to the overall development of production at Cerro Caliche, have been achieved and that the entire campaign to begin gold production at Cerro Caliche remains on track.


John Darch, Sonoro’s Chairman, stated, “From the outset, our pledge to shareholders has been to begin producing gold at Cerro Caliche as quickly as was reasonably achievable.  Our overall objective was, and continues to be, to generate free cash flow to be used to explore and define Cerro Caliche’s considerably larger mineralized potential, thereby shaping the Company’s future growth plans.  This way we hope to minimize the need to issue additional shares and, thereby, avoid diluting our existing shareholders’ interests in the Company, as we fund future exploration and development.”

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.
