Sonoro GOLD Provides Corporate Update
SONORO GOLD PROVIDES CORPORATE UPDATE
VANCOUVER, Canada, September 30, 2025 – Sonoro Gold Corp. (TSXV: SGO | OTCQB: SMOFF
| FRA: 23SP) (“Sonoro” or the “Company”) is pleased to provide a Corporate Update on the Company’s
two mineral projects located in Sonora, Mexico.
Cerro Caliche Gold Project
Sonoro intends to commission an updated Preliminary Economic Assessment ("PEA") on its flagship
Cerro Caliche Gold project currently in the permitting phase for a proposed open pit, heap leach mining
operation. The project’s current PEA was filed in August 2023 and contemplates an initial 9-year mining
operation at 12,000 metric tonnes per day (“mtpd”) with economic parameters based on a gold price
of US $1,800 per ounce.
The updated PEA will reflect an increased gold price as well as higher capital cost and operating cost
estimates. The updated PEA will also include a revised mine plan to align with recent updates to the
project’s Environmental Impact Statement, or Manifestacion de Impacto Ambiental (“MIA”). As stated
in Sonoro’s July 9, 2025 News Release, the recent revisions to the MIA optimize the project’s footprint
while ensuring the project also meets the highest social and environmental standards.
Mining construction and operational activities in Mexico require an approved MIA, as well as ownership
of mineral concessions and surface rights. Sonoro holds 100% of the concession rights for the Cerro
Caliche Gold project. In July 2025, Sonoro announced it had entered into a surface rights agreement
with the owner of the Cerro Prieto Ranch to secure 100% of the surface rights to the Cerro Caliche
concessions and surrounding areas covering an initial 3,908 hectares.

Commencing September 1, 2028, Sonoro’s surface rights will expand to encompass the entire 5,007-
hectare Cerro Prieto Ranch, including the surface rights to the neighbouring Cerro Prieto mine.
The updated PEA will be based on data derived from a total of 55,360 meters of drilling, together with
trenching, supporting assays reporting on approximately 30% of the Cerro Caliche Gold project’s
identified mineralized zones. Sonoro’s technical team is currently conducting an extensive review of
the mineralization both within the previously drilled zones and the remaining 70% of the concession
where limited drilling and extensive surface exploration have demonstrated mineralization in multiple
northwest-trending vein structures. Future drilling campaigns are expected to proceed alongside the
planned development of the proposed mining operation and will focus on expanding Cerro Caliche’s
resource estimate and extending the forecasted mine life.
The Company anticipates completing the updated PEA by the first quarter of 2026.
San Marcial Gold-Silver Project
Management is currently considering options for a strategic reorganization of the Company’s assets,
including consideration of a spin out of its San Marcial gold-silver project into its wholly owned
subsidiary Oronos Gold Corp. (“Oronos”).
Should such a transaction become effective, Sonoro shareholders would end up owning shares in two
public companies: Sonoro, which will continue to focus on the development of the flagship Cerro
Caliche gold project, and Oronos, which would focus on the exploration and development of the San
Marcial gold-silver project.
Sonoro anticipates announcing results of its strategic review process by the end of 2025.
The San Marcial gold-silver project is located in the Santa Ana Municipality of Sonora, Mexico and is
comprised of four contiguous mining concessions . Sonoro acquired the project in 2014 and holds
100% title to the concessions through its wholly owned Mexican subsidiary Minera Breco, S.A. de C.V.
(“Breco”). The project overlays the historic Soledad and San Marcial mine sites and was the subject
of drilling programs during the 1980s and 1990s.
Following the acquisition of San Marcial, an extensive mapping and soil sampling program was
completed by Sonoro and, as previously disclosed, revealed anomalous zones with multiple structural
trends with gold and silver mineralization. Management speculates the San Marcial project may have
the potential for large gold-silver mineralization and believes further exploration is justified, including
a large grid drill program at selected mineralized zones.
Management believes a strategic reorganization to spin out the San Marcial project has the potential
to unlock currently unrecognized value of the project and fund development without diluting
shareholders' holdings in Sonoro.
