Sonoro Gold Announces Expansion of Cerro Caliche Gold Property

Sonoro Gold Corp is pleased to announce that, through its wholly owned Mexican subsidiary, Minera Mar de Plata, it has executed Assignment of Rights Agreements with two residents of Sonora, Mexico to acquire ten mineral concessions along strike and adjacent to the northern and southern boundaries of the Company’s Cerro Caliche gold project in Sonora, Mexico. Both Vendors are at arm’s length to the Company and to its associates and affiliates.

The 10 concessions are contiguous with all the Cerro Caliche Project, covering the northwest (NW)-trending continuation of known mineralized corridors, as well as highly prospective areas to the north with potential extensions of known mineralization, said John Darch, Chair, Sonoro Gold. 

Under the agreements, MMP will acquire a 100% interest in an additional 2,574.16 hectares of mining concessions for a total consideration of US$4 million to be paid in installments totalling US$1 million per year over the next four years. In addition, the Company is assuming responsibility for the payment of outstanding mineral concession fees totaling approximately USD $570,000. The purchase consideration does not include the issuance of any securities nor any grant of a royalty interest.

With this acquisition, Sonoro triples its mineral land position, adding 2,575 hectares, for a total of approximately 3,296 hectares under Sonoro’s control within the project area. 

The acquisition significantly expands the Cerro Caliche property to twenty-five (25) contiguous

mining concessions covering a total area of 3,924.26 ha, potentially extending known mineralized corridors both to the northwest and the southeast. MBN reported on Cerre Caliche`s Achievements early this year. 

“We are pleased to have successfully acquired these strategic mining concessions and expand

the project’s footprint in Mexico’s top gold-producing state. We believe the acquisition not only

increases the project’s exploration potential but may also expand the known mineralized corridors in the northern and southern regions of the property.” commented Sonoro’s President and CEO Kenneth Macleod.  “Our primary objective remains initiating production on Cerro Caliche’s central mineralized zones and utilizing generated cashflow for future exploration and potential resource expansion.” 

On October 12, 2023, Sonoro filed a Technical Report entitled “NI 43-101 Technical Report for the Preliminary Economic Assessment on the Cerro Caliche Project, Sonora, Mexico” authored by Micon International Limited, with an effective date of August 28, 2023 (the “PEA”). As discussed in the PEA, Sonoro has acquired historical geological data from prior exploration programs completed at Cerro Caliche, including drilling, rock sampling and soil sampling data from several of the newly acquired concessions.

In 2011, Paget Southern Resources, a Mexican subsidiary of Pembrook Mining Corp., completed seven diamond drill core holes at El Batamote, approximately 300 meters north of the project’s El Rincón-Bellotoso mineralized zone. Drill holes, logs and assays reviewed by the Company’s geologists identified comparable geological characteristics and grades, suggesting structural continuity of the mineralized corridor. Historical mine workings and exploration completed on newly acquired concessions along the project’s southern boundaries also suggest potential continuation of known gold mineralized zones.

The Cerro Caliche gold project is in the final permitting stage for a proposed open-pit, heap leach mining operation. The property hosts a broadly mineralized low-sulphidation epithermal vein structure with over twenty-five (25) northwest-trending gold mineralized zones along trend and near surface.

In November 2025, Sonoro commenced the preparation of an updated PEA on drilling and assay data completed on approximately 30% of the project’s identified mineralized zones. 

Sonoro anticipates completing the updated PEA during the first quarter of 2026.

Highlights

• Strategic property package totaling 2,575 hectares, covering the continuation of previously identified NW-trending mineralized corridors.

• Northern concessions cover highly prospective areas, corresponding to projected vein trends and mineralized corridors identified through historical drilling, rock sampling, soil sampling, and multiple historical mine workings.

• Historical drilling programs conducted by previous mining companies reported broad mineralized zones with geological characteristics comparable to those observed at the Cerro Caliche Project. These results suggest additional mineralization potential, including possible depth extensions, subject to verification through further exploration.

• The possibility of combined open-pit and underground mining continues to be supported.

Cerro Caliche Expansion Highlights

Sonoro acquired additional ten (10) mineral concessions along strike and adjacent to the northern and southern boundaries of the Company’s Cerro Caliche gold

project in Sonora, Mexico.

Total consideration is USD $4.0 million to be paid in installments four years.

Payments will be monthly for year one and bi-annual for years two to four.

No shares issued and no Royalty granted on the concessions.

Project now expanded to twenty-five (25) concessions covering a total area of 3,924.26 hectares.

Acquisition was critical for future growth of the project ensuring the Company could expand resource and extend LOM

The Company has acquired historical geological data from prior exploration programs completed at Cerro Caliche as well as from several of the newly acquired concessions.

Review of historical geological data indicates comparable geological characteristics and grades as well as potential extensions in depth.

The geology team believes the new claims overlay the continuation of the property’s northern and southern mineral corridors as well as hosting several new prospective areas.

Priority remains getting Cerro Caliche into production based on current resources and using revenues to fund exploration and expansion.

This was a strategic move to position Cerro Caliche as one of the most lucrative players in the region.
