San Marcial Gold-Silver Project, Sonora State, Mexico
The 100% owned San Marcial project covers over 1,000 hectares and is located 30 km southwest of Cerro Caliche and 20 km east of Magna Gold’s San Francisco mine within the prolific Sonora-Mojave Megashear in Sonora State. The concessions surround the sites of the original mine workings of the San Marcial and Soledad mines that were active in the early 1900s. Both mine areas have yielded samples showing high-grade gold and silver mineralization, with broader low-grade zones of disseminated to stockwork forms of mineralization.

On September 16, 2021, Sonoro Gold Corp. reported to correct a calculation error regarding the all-in sustaining cost (“AISC”) disclosed on September 15, 2021, as part of the results from an independent Preliminary Economic Assessment (“PEA”) and updated Mineral Resource Estimate completed on the Company’s Cerro Caliche gold project located in Sonora State, Mexico.
Due to the inadvertent inclusion of certain tax and depreciation expenses in its calculations, the Company reported the AISC to be US$489.3 million LOM, and US$1,462 per ounce (“oz.”) of gold equivalent (“AuEq”). The corrected amounts, as reported in the table below, are US$437 million LOM, and US$1,351 per oz. AuEq.
The other results of the PEA reported in the Company’s September 15, 2021 announcement remain unchanged. The PEA has been prepared in accordance with the requirements of National Instrument 43-101 by D.E.N.M. Engineering Ltd. of Burlington, Ontario (“D.E.N.M.”).
On September 15, 2021, Sonoro Gold Corp. reported the results of an independent Preliminary Economic Assessment (“PEA”) including an updated Mineral Resource Estimate completed on the Company’s Cerro Caliche gold project located in Sonora State, Mexico. PEA Highlights:
On August 30, 2021, Sonoro Gold Corp. has released additional assay results from the continuing surface sampling program at the company's Cerro Caliche gold project in Sonora state, Mexico. 275 new samples were assayed, bringing the total for the current sampling program to 1,567 samples over four mineralized corridors as described in the Company's news release dated July 20, 2021.
Assay results from 17 samples returned grades between 2.5 and 14.3 grams of gold per tonne ("g/t Au"). The image illustrates five high-priority window targets for the upcoming drilling program as each demonstrated strong stockwork quartz veining and outlined broad zones of gold and silver mineralization.
On July 20, 2021, Sonoro Gold Corp. announced that assay results from surface sampling recently completed at the Company’s Cerro Caliche gold project, located in Sonora State, Mexico. The results confirm material extensions of several of the project’s oxide gold mineralized zones and demonstrate linear structural corridors of anomalous gold, silver, and base metal mineralization. This ongoing surface sampling program will be part of the foundation for the upcoming drilling program designed to materially expand and categorize the project’s oxide gold mineralization.
On June 01, 2021, Sonoro Gold Corp. reported that the assay results from the final nine RC drill holes, completing Phase Three of its drilling program at the Cerro Caliche gold project, located in Sonora State, Mexico. As noted in 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 meters which may prove to have significant and positive economic implications for the Company’s proposed Heap Leach Mining Operation (HLMO).
On April 26, 2021, Sonoro Gold Corp. has released assay results from an additional 25 RC drill holes completed at four of the 18 gold mineralized zones within the Cerro Caliche gold concession located in Sonora, Mexico.

The Offering price remains $0.18 per Unit, each composed of one Sonoro Common share and one Common share purchase warrant.
On April 09, 2021, in response to strong investor demand, Sonoro Gold Corp. is increasing its non-brokered private placement first announced on March 29, by providing for an overallotment option of up to 30 per cent (3,333,333 units) over and above the 11,111,111 units previously announced. The offering price remains 18 cents per unit, each composed of one Sonoro common share and one common share purchase warrant.
On April 05, 2021, Sonoro Gold Corp. has released assay results from an additional 12 reverse circulation drill holes completed at its Cerro Caliche gold project in Sonora, Mexico. Results reflect strategic drilling recently concluded at the Buena Suerte gold mineralized zone as well as at the adjacent Buena Vista extension of the Japoneses zone. One additional drill hole was completed at the northern extension of the Japoneses zone, and another two drill holes were completed at the El Colorado gold mineralized zone. It drilled 74.67 m of 0.6 g/t Au at Cerro.
On March 29, 2021, Sonoro Gold Corp. announced that it will undertake a non-brokered private placement offering, consisting of up to 11,111,111 units at a price of 18 cents per unit for gross proceeds of up to $2-million. Each Unit will be composed of one Sonoro Common share and one Common share purchase warrant. Each warrant will entitle the holder thereof to purchase one additional Sonoro Common share for a period of two years from the closing at an exercise price of $0.30 per share.
On March 22, 2021, Sonoro Gold Corp. reported the 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, totaling 1,792 meters, from Buena Suerte and the adjacent Japoneses gold mineralized zones and highlight the following:
On March 11, 2021, Sonoro Gold Corp. reported 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:
On March 03, 2021, Sonoro Gold Corp. reported the bottle roll results from the Company’s Cerro Caliche property in Sonora, Mexico. The samples tested were from four specific mineralized zones: Japoneses, Cuervos, El Colorado/Cabeza Blanca and Buena Suerte, and included associated composites. The testing was conducted at McClelland Laboratories, Inc. in Sparks, Nevada as part of a detailed scope of work consisting of 43 bottle roll tests over 96-hours at a coarse sizing of 80% - 1.7 mm feed size. Subsequent leach recoveries averaged 80.3% for gold and 27.2% for silver. Sodium cyanide consumption rates averaged 0.20 kg/t and lime addition averaged 2.1 kg/t for the bottle roll tests at varying feed grades. These recoveries are similar in all structures and domains while cyanide consumption, which averaged 0.2-0.3 kg/t, together with the amount of lime required for pH control (approximately 2 kg/t) are well within acceptable levels.
On February 16, 2021, Sonoro Gold Corp. has released the latest assay results from its continuing drilling program at the company's Cerro Caliche gold project in Sonora, Mexico. The new results reflect 24 drill holes, totalling 2,591 metres, and highlight the following:

This grant is subject to acceptance for filing by the TSX Venture Exchange.
On January 19, 2021, Sonoro Gold Corp. announced 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).

Buena Suerte: zone extended and widened and remains open along strike. At Buena Suerte, five drill holes extended the zone 100 meters to the northwest and 50 meters to the southeast, increasing the total length along strike to approximately 600 meters:
On December 18, 2020, Sonoro Gold Corp. announced a very favourable results from its current stepout and infill drilling programs. The current programs have demonstrated a material expansion of several mineralized zones, most notably at Japoneses, Buena Suerte, Veta de Oro, El Rincon and El Colorado (see map below). Based on these results, the Company is revising the parameters for a planned Preliminary Economic Assessment (PEA) to assess the viability of Heap Leach Mining Operation (HLMO) by increasing the target conceptual capacity from 8,000 tonnes per day (tpd) to 20,000 tpd. It drilled 11.25 m of 1.08 g/t Au at Cerro.
