SGO · Price

Executive Summary

  • Sonoro Gold plans to release an updated Preliminary Economic Assessment (PEA) for its flagship Cerro Caliche gold project in Q1 2026, reflecting higher gold price assumptions and revised capital/operating costs.
  • The company is evaluating a strategic reorganization that could spin out the San Marcial gold‑silver project into a new wholly‑owned subsidiary, Oronos Gold Corp., with results expected by end‑2025.
  • Surface rights for Cerro Caliche will expand to cover the entire 5,007‑hectare Cerro Prieto Ranch starting September 1 2028, securing full control of the mining area.

Key Details

  • Cerro Caliche Updated PEA
  • Current PEA (filed Aug 2023) assumes a nine‑year mine life at 12,000 t/d and gold price $1,800/oz.
  • Updated PEA will incorporate:
    • Increased gold price assumption.
    • Higher capital and operating cost estimates.
    • Revised mine plan aligned with recent Environmental Impact Statement (MIA) updates.
  • Data basis: 55,360 m of drilling + trenching, covering ~30 % of identified mineralized zones; remaining 70 % under limited drill but extensive surface exploration.

  • Completion target: Q1 2026.

  • Surface Rights Expansion

  • July 2025 agreement secured 100 % surface rights to Cerro Prieto Ranch (initial 3,908 ha).

  • Effective Sept 1 2028, rights will extend to the full 5,007 ha area, including neighboring Cerro Prieto mine.

  • San Marcial Strategic Review

  • Management considering spin‑out of San Marcial gold‑silver project into wholly‑owned subsidiary Oronos Gold Corp.
  • If executed, Sonoro shareholders would hold shares in both Sonoro (Cerro Caliche focus) and Oronos (San Marcial focus).

  • Anticipated announcement of review results by end 2025.

  • San Marcial Project Overview

  • Located in Santa Ana municipality, Sonora; four contiguous concessions acquired in 2014 via Minera Breco SA de CV.
  • Historic drilling (1980s‑1990s) plus recent mapping and soil sampling identified anomalous gold‑silver zones with multiple structural trends.

  • Management plans a large‑grid drill program to test potential for significant mineralization.

  • Strategic Rationale

  • Spin‑out could unlock hidden value in San Marcial and provide financing for development without diluting existing Sonoro shareholders.
