SONORO GOLD CORP. ANNOUNCES HIGH GRADE INTERCEPTS AT BUENA SUERTE AND JAPONESES; ZONES CLOSE TO MERGING

Sonoro Gold Corp. has released assay results from its continuing drill program at the company's Cerro Caliche gold project in Sonora, Mexico. The new results reflect 20 RC drill holes, totalling 1,792 metres, from the Buena Suerte and adjacent Japoneses gold-mineralized zones and highlight the following:

  • Spacing between the Buena Suerte and Japoneses zones has been reduced to approximately 100 metres in the northern extensions, indicating the zones may merge with further infill drilling;
  • Drill holes SCR-201, SCR-203, SCR-205 and SCR-207 at the 200-metre, high-grade north extension of Buena Suerte all cut high-grade intercepts;
  • Drilling at the southwest extension of Buena Suerte identifies a 100-metre-long high-grade splay vein zone and widens the Buena Suerte zone toward the west;
  • High-grade zone identified at the northwest extension of Japoneses, approximately 150 metres east of the 200-metre-long high-grade zone at Buena Suerte.

Buena Suerte gold mineralization zone

On the southwest flank of the recently extended Buena Suerte zone, a new 100-metre-long high-grade vein, or splay, was identified with drill hole SCR-219, which intercepted 1.5 metres averaging 6.475 grams per tonne gold within a larger interval of 16.76 metres averaging 1.427 grams per tonne gold. Drill hole SCR-158, located 100 metres northwest of SCR-219, earlier reported a 6.10-metre intercept averaging 0.7 gram per tonne gold, including 3.05 metres averaging 1.34 grams per tonne gold. The northwest-trending splay is located midway between the Buena Suerte vein and the El Quince vein 200 metres farther west.

On the eastern flank of the Buena Suerte zone, drill hole SCR-201 intercepted 9.14 metres averaging 0.74 gram per tonne gold. Within the zone's main vein, drill hole SCR-209 intercepted 4.57 metres averaging 0.77 gram per tonne gold, and, 70 metres to the southeast, drill hole SRC-211 intercepted 3.05 metres averaging 4.766 grams per tonne gold.

Highlights from Buena Suerte are as follows:

  • SCR-201 intercepted 9.14 metres averaging 0.74 gram per tonne gold, including 1.52 metres averaging 2.096 grams per tonne gold.
  • SCR-203 intercepted 6.09 metres averaging 0.712 gram per tonne gold, including 1.53 metres averaging 2.04 grams per tonne gold.
  • SCR-205 intercepted 9.14 metres averaging 0.593 gram per tonne gold, including 1.53 metres averaging 1.528 grams per tonne gold.
  • SCR-207 intercepted 3.05 metres averaging 0.621 gram per tonne gold and 1.52 metres averaging 1.292 grams per tonne gold.
  • SCR-209 intercepted 4.57 metres averaging 0.770 gram per tonne gold, including 1.53 metres averaging 1.786 grams per tonne gold.
  • SCR-211 intercepted 3.05 metres averaging 4.766 grams per tonne gold.
  • SCR-219 intercepted 16.76 metres averaging 1.427 grams per tonne gold, including 1.52 metres averaging 6.475 grams per tonne gold.

Japoneses gold mineralization zone

On the western flank of the Japoneses gold-mineralized zone, directly adjacent to the eastern flank of the Buena Suerte gold-mineralized zone, the distance between the two zones was reduced to approximately 100 metres, with drill hole SCR-218 intercepting 22.86 metres averaging 0.505 gram per tonne gold and drill hole SCR-220 intercepting 22.86 metres averaging 0.505 gram per tonne gold. Future drilling within this area will continue to investigate surface exposures, which include epithermal quartz veins in the highly silicified outcropping rock consisting of quartzite and rhyolitic intrusive.

Drilling results from the west-central flank of the Japoneses zone outline additional mineralized material with drill hole SCR-204, which intercepted 10.67 metres averaging 1.355 grams per tonne gold, including 1.53 metres averaging 6.329 grams per tonne gold. In the southern portion of Japoneses, infill drilling cut multiple veins, demonstrating an extensive shallow oxide gold mineralization, with drill hole SCR-214 intercepting 18.29 metres averaging 0.577 gram per tonne gold and drill hole SCR-215 intercepting 12.2 metres averaging 0.517 gram per tonne gold.

Highlights from Japoneses are as follows:

  • SCR-204 intercepted 10.67 metres averaging 1.355 grams per tonne gold, including 1.53 metres averaging 6.329 grams per tonne gold.
  • SCR-214 intercepted 18.29 metres averaging 0.577 gram per tonne gold, including 1.52 metres averaging 1.972 grams per tonne gold.
  • SCR-215 intercepted 12.20 metres averaging 0.517 gram per tonne gold.
  • SCR-218 intercepted 22.86 metres averaging 0.505 gram per tonne gold, including 1.52 metres averaging 1.952 grams per tonne gold.
  • SCR-220 intercepted 22.86 metres averaging 0.534 gram per tonne gold, including 1.53 metres averaging 1.843 grams per tonne gold.

Kenneth MacLeod, president and chief executive officer of Sonoro, stated: "With over 44,500 metres of drilling completed on Cerro Caliche to date, we are pleased to open the data room to geological and mining consultants, Micon International, for preparation of an updated NI [National Instrument] 43-101 resource report. Additional assays for drilling to the end of March will be provided to Micon by mid-April for inclusion in the resource report, which is anticipated to be completed in mid-2021."

John Darch, chairman of Sonoro, added: "The results continue to build a case for a substantial increase in our upcoming NI 43-101 resource update as both zones look increasingly likely to coalesce into a single body of shallow, oxide gold mineralization, which may justify a single larger pit. At the same time, the discovery of a high-grade gold vein near the Buena Suerte's southwestern extent not only adds to the project's resource potential, but it also illustrates the project's potential for high-grade gold veins."

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 from the drill site the samples and transports them directly to the preparation laboratory in Hermosillo, Sonora. At the preparation laboratory, a split part of each sample (about 500 grams) is reduced through crushing, splitting and pulverization. Thirty grams of each pulverized sample are split apart in the Hermosillo laboratory and undergo a fire assay for gold content by reducing the fire assay to a concentrated button of material that is dissolved in acids and the gold content determined by atomic absorption. About another 200 grams of each sample are sent by BV to its laboratory in Vancouver, Canada, and dissolved there in aqua regia for multielement ICP analysis, including silver.

No QA/QC issues were noted with the results received from the laboratory.

Geologic description

Cerro Caliche is located 45 kilometres east-southeast of Magdalena de Kino in the Cucurpe-Sonora megadistrict 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 megadistrict include variants of epithermal low-sulphidation veins and related mineralized dikes and associated volcanic domes. Local altered and mineralized felsic dikes cut the mineralized metasedimentary rock units and may be associated with mineralization both in the dikes and metasedimentary rocks.

Qualified person statement

Stephen Kenwood, PGeo, a director of Sonoro, is a qualified person within the context of NI 43-101, and he 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 company.
