SONORO GOLD COMPLETES PHASE 3 DRILL PROGRAM AND MOVES TOWARDS AN UPDATED N1 43-101 TECHNICAL REPORT AND NEW PEA FOR CERRO CALICHE

Sonoro Gold Corp. has released assay results from the final nine RC (reverse circulation) drill holes, completing phase 3 of its drilling program at the Cerro Caliche gold project, located in Sonora state, Mexico. As noted in the news releases dated April 5, 2021, and April 26, 2021, the company extended drilling activities to investigate the potential merging of the Japoneses and Buena Suerte zones into a single body of shallow, oxide gold mineralization. Recent results indicate a coalescence of the two zones over a minimum length of 400 metres, which may prove to have significant and positive economic implications for the company's proposed heap leach mining operation (HLMO).

Two independent National Instrument 43-101 technical reports, scheduled to be filed in July, 2021, will provide valuable information as to whether the identified mineralization is sufficient to support a proposed HLMO with an initial operating capacity of up to 15,000 tonnes per day. As previously announced, the company engaged DENM Engineering Ltd. to prepare a preliminary economic assessment (PEA) and Micon International Ltd. to prepare a mineral resource estimate. The mineral resource estimate will include all prior and current exploration data up to April, 2021. To date, the company has drilled and assayed results from over 34,500 metres of drilling, including over 25,000 metres of new drilling since September, 2020. When combined with historical data, total exploration at Cerro Caliche totals over 47,500 metres, 433 drill holes and 9,365 surface samples.

Drilling activities on the concession are currently paused to provide the exploration team time to ensure all data and assistance are available to the independent consultants and to implement any recommendations set forth in the anticipated technical reports. Subject to the terms of project financing, drilling is scheduled to resume by the end of the third quarter of 2021 to continue expanding mineralization and investigating potential high-grade targets.

Potential coalescence of Japoneses and Buena Suerte gold zones

The final nine drill holes were completed along the narrowing gap between the northwest extension of the Japoneses zone, known as the Buena Vista fault vein zone, and the east flank of the Buena Suerte zone. Four of the drill holes cut the east side of Buena Suerte, with drill hole SCR-264 intercepting 15.24 metres averaging 0.764 gram of gold per tonne, including 1.52 metres averaging 2.402 grams per tonne gold. Drill hole SCR-261 encountered continuous mineralization from surface but intercepted an artisanal mine working at 19.81 metres. The rig was moved six metres and the hole was redrilled as SCR-261B, which intercepted a total of 35 metres of gold mineralization, including 1.5 metres averaging 1.23 grams per tonne gold.

In the northern extent, roughly at the centre of the 150-metre gap separating Japoneses and Buena Suerte, drill hole SCR-262 cut multiple intervals of gold mineralization totalling 52 metres from surface, including 1.53 metres averaging 2.171 grams per tonne gold. While this area was previously considered to be outside of the mineralized gold zones, drilling results confirm the material presence of gold mineralization and further support the development of a single pit to mine gold mineralization from both the Japoneses and Buena Suerte zones.

These final drilling results mark the conclusion of a highly successful and intense drilling program. As noted herein, management expects two independent NI 43-101-compliant reports to update the resource size and classification and determine whether it is sufficient to support the company's proposed HLMO with a conceptual operation of up to 15,000 tonnes per day.

Mel Herdrick, Sonoro's vice-president of exploration, noted: "I am pleased that these latest drill holes show the area between the two gold-bearing zones, which was previously considered barren, does in fact carry gold mineralization. It is a very encouraging ending for what has been a very effective drill program. There remains much more potential in the areas we plan to drill later this year and next, and I expect that this drilling will continue to define and materially expand and categorize the project's oxide gold mineralization."

Kenneth MacLeod, Sonoro's president and chief executive officer, added: "We have reached a watershed juncture in the development of Sonoro as we are now making the transition from an exploration company to our aspirational goal of becoming a gold producer in early 2022. We are grateful for the support of our shareholders over the past three years as we strive to make Cerro Caliche the next mining success story in Mexico."

John Darch, Sonoro's chairman, commented: "These final drill results reinforce the potential for the Japoneses/Buena Vista and Buena Suerte zones to be assessed as a single pit with all of the attendant cost savings that a single pit may make possible. They also mark the conclusion of an exceptional year, where Sonoro has been transformed from an exploration junior to a development-stage company with a goal of achieving production early next year. Our strategy of exploring and developing Cerro Caliche's extensive shallow oxide gold mineralization while advancing towards becoming a gold producer is advancing as we had hoped. We anticipate this will be confirmed with the filing of the Micon International's [NI] 43-101 technical report on an updated resource estimate as well as with the filling of the anticipated PEA regarding the proposed project's economics."

All reported intervals in this news report are 45-degree inclined drill holes cutting an assumed 60-degree- to 90-degree-dipping vein zone toward the drill hole, thus the intercept is considered to be approximately 20 degrees or less from having a perpendicular intersection. The true widths of reported drill widths are anticipated to be about 75 per cent or more of intercept widths reported.

The relevant table illustrates the exploration history of the Cerro Caliche concession. Sonoro commenced drilling in October, 2018, and completed the first two phases by June, 2019, for a total of 96 drill holes totalling 10,328 metres. The company initiated phase 3 drilling in August, 2020, and completed the program in April, 2021. During phase 3, Sonoro completed 170 RC drill holes (18,206.57 metres) and 48 diamond drill core holes, including 11 metallurgical PQ drill holes (6,014.9 metres) for a phase 3 total of 24,221.47 metres of drilling. Total Sonoro drilling amounts to 34,549.63 metres in 314 drill holes. The earlier Corex and Paget drilling of 104 drill holes over 10,762.67 metres brings the drilling database to a total of 45,312.3 metres over 418 drill holes. Additionally, the data from earlier drilling by Cambior totalling 2,244.85 metres over 15 holes are appended to the Sonoro database.

Quality assurance/quality control 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 from the drill site 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 is determined by atomic absorption. About another 200 grams of each sample are sent by BV to its Vancouver, Canada, laboratory and dissolved in aqua regia for multielement ICP analysis, including silver.

No quality assurance/quality control 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 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.
