SONORO GOLD COMPLETES PHASE IV DRILLING PROGRAM AT CERRO CALICHE REPORTS MULTIPLE HIGHER-GRADE INTERCEPTS & EXPANSION OF GOLD MINERALIZED ZONES
Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) (“Sonoro” or the “Company”) is pleased to report assay results from the final seven drill holes, completing the Phase IV drilling program at its Cerro Caliche gold project in Sonora, Mexico. In total, the Company completed over 7,200 meters of reverse circulation drilling with 63 drill holes which returned multiple higher-grade gold intercepts and demonstrated the expansion of several known mineralized gold zones within the Cerro Caliche concession.
The objective of the program was to increase the estimated size and grade of the project’s oxide gold mineralization, as well as to extend the estimated life of a proposed heap leach mining operation as outlined in the Preliminary Economic Assessment (“PEA”) and updated Mineral Resource Estimate filed under the Company’s profile on SEDAR on October 29, 2021.
On May 9, 2022, the Company announced positive results of an updated PEA based on an optimized mine plan to potentially increase the project’s previously reported economic parameters. The updated report was based on the same mineral resource estimate contained in the Company’s initial PEA and did not include the new geological data from the Phase IV campaign.
Drilling results from the now completed Phase IV campaign will be included in an updated resource estimation scheduled to be announced in the fall of 2022. The economic impact of the updated resource on the proposed heap leach mining operation is also to be assessed and will be contemplated in a further technical report.
Mel Herdrick, Sonoro’s VP Exploration, commented, “Phase four has been a successful drilling campaign with continued reporting of mineralized extensions and higher-grade intercepts.As the project continues to move through the current permitting phase, the objective of the exploration team now is to refine our understanding of the new extensions and higher-grade zones, as well as the potential impact of the new drilling data on the project’s resource.”
Kenneth MacLeod, Sonoro’s President and CEO, added, “The completion of the drilling program is another important milestone in the development of Cerro Caliche. Last month we announced the positive results of an updated PEA and are currently assessing the potential economic impact of the new drilling data on the proposed heap leach mining operation. An updated resource estimation is expected to be filed this fall and we will continue to work on securing project financing and moving the project forward.”
John Darch, Sonoro’s Chairman, noted, “With regards to the successful completion of the drilling program, the Board would like to specifically commend the efforts of our exploration team in Mexico, most notably VP of Exploration Mel Herdrick, VP of Operations Jorge Diaz and Chief Geologist Oscar Gonzalez.These individuals have been instrumental in the success of Cerro Caliche’s exploration and development programs.”
Final Drilling Results
The results announced in this news release reflect drilling activity conducted at the Abejas gold mineralized zone located at the eastern perimeter of the Central Pit Zone, with the reported intercepts situated outside of the pit shell used to calculate the mineral resource estimate in the initial PEA.
Highlights are as follows:
- SCR-321 intercepted 15.24m averaging 1.336 g/t Au; including 4.57m averaging 3.657 g/t Au;
- SCR-322 intercepted 18.29m averaging 0.785 g/t Au; including 1.52m averaging 4.88 g/t Au.
The map below illustrates the location of the drill holes.
Figure 1: Drill holes at Abejas
AbejasMineralizedZone
The Abejas zone is in the most eastern part of the property’s main body of gold mineralization where seven drill holes demonstrated an approximate 30-meter southernly extension outside of the estimated resource pit shell. Three of the seven drill holes also returned higher-grade intercepts, including drill hole SCR-321 which intercepted 15.24 meters averaging 1.336 grams of gold per tonne (“g/t Au”), including 4.57 meters averaging 3.657 g/t Au and drill hole SCR-322 which intercepted 18.29 meters averaging 0.785 g/t Au, including 1.52 meters averaging 4.880 g/t Au.
The Abejas extension is terminated by a northeasterly trending fault that continues southwesterly to offset the Los Cuervos mineralization. Further detailed work around the faulted Abejas zone could determine the same relationship with possible additional targets.
Both drill holes SCR-321 and SCR-322 correlate with other plotted vein projections intersected further north and the geology of the Abejas zone is similar to the Japoneses gold mineralized zone with most rock drilled being Jurassic-Cretaceous metasedimentary quartzite, shale and local limestone beds. Structures with quartz vein fillings cross with the normal northwest orientation and are part of the wider zone of sheeted gold mineralized veins.
The Abejas zone is about 600 meters long and is traced further northwesterly to join the Veta del Oro zone which has a long, well-defined vein zone with higher gold and silver grades. Anomalous silver content is also present in the results with 24.9 grams per tonne intercepted in drill-hole SCR-321 between depths of 9.14 and 10.67 meters. Lead is also anomalous with gold but in broader anomalies. Silicification is common in the area, especially close to the vein zones.
The table below provides the assay results for the complete list of reported drill holes. Vein intersections appear to be near true widths reported from assay intervals. Drill holes cross the veins with 45-degree inclination, while veins appear to have dips around 50 to 60 degrees.
Drill collar locations, azimuths and dips for the drill holes included are provided in the table below.
Phase IV Drilling Program
In November 2021, the Company announced it had resumed drilling with the objective of increasing the estimated size and grade of the project’s oxide gold mineralization. An independent PEA completed on the Cerro Caliche project demonstrated a potentially viable seven-year open pit, heap leach mining operation with a production capacity of up to 15,000 tonnes per day. An increase in the size and grade of the project’s resource may not only extend the life of the proposed operation but may also improve the overall economics of the project.
The Phase IV drilling program was designed to potentially expand known mineralized zones, including zones excluded from the mineral resource estimate due to lack of required drilling density. The program also drilled potential higher-grade targets identified by a surface sampling program completed in the summer of 2021.
The map below illustrates the location of drill holes completed during the Phase IV drilling program.
Figure 2: Drill holes at Cerro Caliche
El ColoradoMineralized Gold Zone
Drilling completed at El Colorado provided the Company with an improved structural understanding of the complexity of the mineralized zone, including higher-grade blind (lack of surface exposure) structures or shoots. While the zone is complexly faulted and veined, the additional drill holes completed during the Phase IV program began to reveal coherent high-grade gold bearing veins, as well as anastomosing veins diverging and branching from zone’s main veins.
Collectively, these suggest an increased potential for a higher-grade open pit which, if confirmed, may also potentially increase the average gold content of the entire mineralized zone.
As previously announced, drilling completed at El Colorado returned multiple higher-grade gold intercepts within larger intervals of high-grade gold mineralization including drill hole SCR-286 which intercepted high-grade gold mineralization at the deepest level of El Colorado’s epithermal system drilled to date.
Near the bottom of the hole, a 27.43-meter intercept averaged 5.36 g/t Au, including 4.57 meters averaging 7.16 g/t Au, and 4.57 meters of 22.09 g/t Au, including 1.53 meters averaging 46.5 g/t Au and 1.52 meters averaging 3.25 g/t Au.
Figure 3: Interpretive Cross Section at El Colorado
A total of 20 additional drill holes were completed outside of the estimated resource pit shell used to calculate the zone’s gold resource. As previously announced, five drill holes demonstrated an expansion of approximately 30 meters along the northwestern side of the estimated resource pit shell.
Oxidized mineralized material is present throughout El Colorado with no significant sulfide minerals present. The geology is a mixture of silicified meta-sedimentary units intruded by a silicified and argillic altered quartz porphyry igneous body and, in deeper parts, granodiorite with dioritic to andesitic dikes. The mineralized structures trending north 10 west and dipping northeasterly cross the zone extending southerly from the Cabeza Blanca quartz veins.
Guadalupe Mineralized Gold Zone
Located to the north of El Colorado, and parallel to the Cabeza Blanca mineralized gold zone, Guadalupe was excluded from the updated mineral resource estimate due to its lack of sufficient drilling density.
Drilling completed at Guadalupe during Phase IV returned intercepts of higher-grade gold vein material at depth, including previously announced drill hole SCR-280 which intercepted 3.05 meters averaging 19.56 g/t Au, including 1.53 meters averaging 37.90 g/t Au. The higher-grade zone’s repetitive character likely is due to a higher degree of shearing at the footwall of the Guadalupe vein structure.
Figure 4: Drill holes at El Rincon
The footwall shows stronger shear character, including mylonitic vein textures locally, and suggests the potential for development and further exploration in areas to the west where numerous veins are present. Guadalupe’s entire structural zone may be permissive over more than 100 meters width.
Buena Suerte Mineralized Gold Zone
Buena Suerte is approximately 300 meters east of El Colorado and drilling completed during Phase IV extended the Buena Suerte vein system to the southwest and potentially increased the zone’s estimated resource. Mineralization was shown to extend further south another 500 meters, but additional drilling is required to follow the vein zones located beneath a cover of thick soils and colluvium.
As previously reported, drill hole SCR-318 returned elevated gold content of 1.52 meters averaging 9.57 g/t Au and 28.95 meters averaging 1.021 g/t Au, including 1.53 meters averaging 2.07 g/t Au. The potential of the mineralization connecting to other high grade drill intercepts further north requires additional investigation.
El Rincon Mineralized Gold Zone
Drilling completed between two separate pit shells at El Rincon confirmed continuation of mineralization between the resource segments along a rhyolitic dike. A total of 6 drill holes were completed during the Phase IV campaign over approximately one kilometer of strike length. As previously announced, SCR-304 intercepted 1.52 meters averaging 2.49 g/t Au and drill hole SCR-305 intercepted 36.5 meters averaging 0.535 g/t Au, including 1.53 meters averaging 3.59 g/t Au and 1.53 meters averaging 3.32 g/t Au.
Much of the gold and higher-grade silver is dispersed well into the dike. The structure’s trend is azimuth 310 with dip of 85 northwest to vertical. This vein structure cuts both rhyolitic dikes and sills and bedded meta-sedimentary rocks with gold-silver mineralization occurring in both rock types. The El Rincon vein zones are generally parallel to, or along, the rhyolite dike margins.
La Espanola Mineralized Gold Zone
Another area excluded from the Mineral Resource Estimate was La Espanola, located in the southeast region of the property. Southeast of El Rincon, the mineralization of La Espanola is also localized in rhyolitic dike. Six scout drill holes completed during Phase IV suggest lower grade mineralization in the northward extension of the vein zone.
To date, the Company has completed over 41,800 meters of drilling at Cerro Caliche and, with the inclusion of data from prior operators, accumulated a database of almost 55,000 meters of geological data on the project, including multiple high-grade gold intercepts as well as broad zones of stockwork and disseminated material. Geological data from the Phase IV drilling campaign will be included in an updated resource estimate scheduled to be filed in fall 2022.
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.

SONORO GOLD REPORTS HIGHER-GRADE INTERCEPTS AND EXPANDS GOLD MINERALIZATION AT CERRO CALICHE GOLD PROJECT
Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF | FRA: 23SP) (“Sonoro” or the “Company”) pleased to report assay results from an additional 10 drill holes completed at its Cerro Caliche gold project in Sonora, Mexico. Results reflect drilling conducted at El Colorado and Buena Suerte gold mineralized zones where intercepts include 1.52 meters averaging 9.57 grams of gold per tonne (“g/t Au”), 28.95 meters averaging 1.021 g/t Au and 10.67 meters averaging 1.183 g/t Au. As with drilling results announced on May 17, 2022, current intercepts are also situated outside of the pit shells used to calculate the mineral resource estimate as part of an updated Preliminary Economic Assessment (“PEA”) announced May 9, 2022, for a proposed heap leach mining operation.
Highlights are as follows:
- SCR-313 intercepted 21.34m averaging 0.557 g/t Au, including 3.04m averaging 1.523 g/t Au.
- SCR-314 intercepted 3.05m averaging 1.185 g/t Au, including 1.52m averaging 2.19 g/t Au; and 7.62m averaging 0.72 g/t Au, including 1.53m averaging 1.635.
- SCR-315 intercepted 10.67m averaging 1.183 g/t Au, including 1.52m averaging 3.27 g/t Au; and 4.57m averaging 1.087 g/t Au, including 1.53m averaging 2.28 g/t Au.
- SCR-318 intercepted 1.52m averaging 9.57 g/t Au and 28.95m averaging 1.021 g/t Au; including 1.53m averaging 2.07 g/t Au, including 3.05m averaging 2.706 g/t Au.
The map below illustrates the location of the drill holes.
Figure 1: New Drill Holes at El Colorado and Buena Suerte
Results from seven additional drill holes completed at the Abejas gold mineralized zone are still pending and will be announced next month, concluding the Phase IV drilling program at Cerro Caliche. Geological data from this latest drilling campaign will be included in a further updated resource estimate scheduled to be announced in the summer of 2022. The updated technical report will also assess the potential economic impact of the new drilling data on the proposed heap leach mining operation.
Mel Herdrick, Sonoro’s Vice President of Exploration, noted that “I continue to be encouraged by the results of the Phase IV drilling campaign which has returned multiple higher-grade intercepts and demonstrated resource growth potential near surface and at depth. These latest assay interceptsalso indicate continued expansion of El Colorado and Buena Suerte mineralized gold zones outside of the pit shellsused to calculate the resource estimate for the initial PEA. The potential expansionwill be confirmed in anupdated resource estimateexpected to be completedover the next few months.”
Kenneth MacLeod, Sonoro’s President and CEO stated, “With the updatedmineral resource estimation potentially demonstrating an increase in multiple gold mineralized zones at Cerro Caliche, we are now reviewing the additional work involved to incorporate the new data into an updated technical report on the proposed mining operation.This has been a successful drilling campaign and I look forward to sharing the final drilling results with our shareholders.”
John Darch, Sonoro’s Chairman, added, “I amvery pleased with the latest results as they indicate a potential increase in both the size and grade of the of the project’s oxide gold mineralization. As announced when drilling resumed in November 2021, the objective of this drilling program wasto expand the resource and potentially improve the economics and mine life of the proposed heap leach operation.We are becoming more optimistic that we may meet this objective.“
El Colorado Gold Mineralized Zone
Five drill holes were completed at El Colorado extending mineralization approximately 30-meters along the northwestern side of the estimated resource pit shell. Shallow gold mineralization was cut in all five drill holes with drill holes SCR-313, SCR-314 and SCR-315 returning multiple higher-grade intercepts.
Drill hole SCR-315 tested for a possible extension of the mineralization contained within the northernmost extent of the pit shell and beginning at 7.62 meters, it intercepted 10.67 meters averaging 1.183 g/t Au, including 1.52 meters averaging 3.27 g/t Au and 4.57 meters averaging 1.087 g/t Au, including 1.53 meters averaging 2.28 g/t Au.
Approximately 50 meters northwest of the previously reported drill hole SCR-307, which intercepted 9.14 meters of 9.577 g/t Au, drill hole SCR-313 tested the outside perimeter of the pit shell, intercepting 21.34 meters of 0.557 g/t Au, including 3.04 meters of 1.523 g/t Au.
Figure 2: Drill Holes at El Colorado and Buena Suerte
Buena Suerte Vein System
Located approximately 300 meters east of El Colorado, five drill holes extended the Buena Suerte vein system to the southwest with drill holes SCR-318, SCR-319 and SCR-320 located immediately outside the resource pit shell boundary.
Drill hole SCR-318 cut strong gold mineralization intercepting 1.52 meters averaging 9.57 g/t Au and 28.95 meters averaging 1.021 g/t Au, including 1.53 meters averaging 2.07 g/t Au, as well as 3.05 meters averaging 2.706 g/t Au. Drill hole SCR-320 intercepted 4.57 meters averaging 0.851 g/t Au, including 1.53 meters averaging 2.11 g/t Au.
Drill holes SCR-316 and SCR-317 are located further south with assay results of only short uneconomic intervals, possibly due to an unmapped fault having shifted vein extensions to other positions.

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.

Canada Silver Cobalt Announces Airborne VTEM Geophysical Survey at its Lowney-Lac Edouard Property East of La Tuque in Central Quebec
The VTEM Plus survey will be flown via helicopter later in June, and aims to identify discrete conductive anomalies near surface
Coquitlam, BC – TheNewswire – May 24, 2022 – Canada Silver Cobalt Works Inc. (TSXV:CCW) (OTC:CCWOF) (Frankfurt:4T9B) (the “Company” or “Canada Silver Cobalt”) is pleased to announce it is planning an airborne VTEM Plus geophysical survey at its Lowney-Lac Edouard property south of the historical Lac Edouard Ni-Cu-Co mine in Central Quebec.
The property is of particular interest to the technical team due to several important factors:
- 1) The significant regional gravity anomaly that was identified by a previous airborne SGL survey (please see Figure 2).
- 2) The positive geological context, including a favorable lithological unit that appears to correlate with the gravity anomaly.
- 3) The sediment lake samples that returned elevated nickel and copper, which appears to also correlate with the gravity anomaly (please see Figure 3).
- 4) The proximity to the old Lac Edouard Ni-Cu-Co past producing mine.
The VTEM survey will be completed via helicopter by Geotech, is a global leader in technological innovation for airborne geophysical survey mapping, interpretation and analysis. The Company intends to identify near surface conductors which will help guide the field work this summer. The VTEM survey and field work will help provide a better understanding of the area and hopefully lead to a drill program. In addition, the property is bordered by several other large companies such as Rio Tinto Exploration Canada and Brunswick Exploration Inc. (please see Figure 1).
“We believe that a VTEM survey will provide the necessary information to better understand the property. Based on what we have so far, this property has great potential and fits within our objective to become an important supplier of battery metals material to the EV market. The fact that we have big players surrounding us shows that we’re in the right location.” states Matt Halliday, P.Geo., President, COO and VP Exploration.

About Canada Silver Cobalt Works Inc.
Canada Silver Cobalt Works Inc. recently discovered a major high-grade silver vein system at Castle East located 1.5 km from its 100%-owned, past-producing Castle Mine near Gowganda in the prolific and world-class silver-cobalt mining district of Northern Ontario. The Company has completed a 60,000m drill program aimed at expanding the size of the deposit with an update to the resource estimate underway.
In May 2020, based on a small initial drill program, the Company published the region’s first 43-101 resource estimate that contained a total of 7.56 million ounces of silver in Inferred resources, comprising very high-grade silver (8,582 grams per tonne un-cut or 250.2 oz/ton) in 27,400 tonnes of material from two sections (1A and 1B) of the Castle East Robinson Zone, beginning at a vertical depth of approximately 400 meters. Note that mineral resources that are not mineral reserves do not have demonstrated economic viability. Please refer to Canada Silver Cobalt Works Press Release May 28, 2020, for the resource estimate. Report reference: Rachidi, M. 2020, NI 43-101 Technical Report Mineral Resource Estimate for Castle East, Robinson Zone, Ontario, Canada, with an effective date of May 28, 2020, and a signature date of July 13, 2020.
The Company also has: (1) 14 battery metals properties in Northern Quebec where it has recently completed a nearly 10,000-metre drill program on the Graal property; and (2) the prospective 1,000-hectare Eby-Otto gold property close to Agnico Eagle’s high-grade Macassa Mine near Kirkland Lake, Ontario where it will be exploring in 2022.
Canada Silver Cobalt’s flagship silver-cobalt Castle mine and 78 sq. km Castle Property feature strong exploration upside for silver, cobalt, nickel, gold, and copper. With underground access at the fully owned Castle Mine, an exceptional high-grade silver discovery at Castle East, a pilot plant to produce cobalt-rich gravity concentrates, a processing facility (TTL Laboratories) in the town of Cobalt, and a proprietary hydrometallurgical process known as Re-2Ox (for the creation of technical-grade cobalt sulphate as well as nickel-manganese-cobalt (NMC) formulations), Canada Silver Cobalt is strategically positioned to become a Canadian leader in the silver-cobalt space.
