A low-sulphidation epithermal gold-silver prospect straddling the Sinaloa–Durango state border — with three drill-ready showings, a completed NI 43-101 technical report, and a riverside position in one of Mexico's most mineral-rich geological corridors.

Opportunity Overview

Project Río is a low-sulphidation epithermal gold-silver prospect located at the Sinaloa–Durango state border, defined by the Baluarte River valley within the southern Sierra Madre Occidental. The NI 43-101 Technical Report (Michel Boily, PhD., P.Géo., Maya Gold and Silver Inc., April 2008) covers three showings — La Campana, Santa Rita, and El Sacrificio — all returning meaningful Au-Ag values in grab and channel sampling programs conducted in 2007–2008.

The property sits within a Tertiary-age, predominantly silicic volcanic belt that is the same geological environment hosting numerous producing and advanced-stage Au-Ag mines across the Sierra Madre Occidental. The La Campana showing alone has been traced for 1 km of strike length, with a principal adit developed along the main structure and multiple parallel vein sets identified. Santa Rita presents a system of three parallel Au-Ag mineralized quartz veins oriented 10° and dipping 70° east.

All three showings have been surface-sampled, mapped, and geochemically analyzed. No drilling has been completed — the entire subsurface is uncommitted, making this a high-upside pre-drill exploration opportunity with a completed technical foundation.

Key Competitive Advantages

Three Distinct Drill Targets
La Campana, Santa Rita, and El Sacrificio are independently mapped, sampled, and geochemically characterized showings — each with distinct structural controls and mineralization styles. Three independent targets on one property package is an exceptional setup for a Phase I drill program.
NI 43-101 Technical Foundation
A fully compliant NI 43-101 report prepared by Michel Boily, PhD., P.Géo. (GÉON, for Maya Gold and Silver Inc.) defines the geological framework and provides a formal Phase I drill recommendation with detailed budget. No need to commission a preliminary scoping study — the technical groundwork is complete.
Baluarte River Access
The Baluarte River defines the property boundary and provides natural water access for any future processing facility — a significant infrastructure advantage in remote Sinaloa-Durango terrain where water sourcing is typically a major capital line item for mine developers.
Proven Structural Style
Mineralization at La Campana displays open-space and drusy vein textures typical of productive low-sulphidation epithermal systems in the Sierra Madre belt. The structural model is well-understood, and the geological environment is the same as numerous nearby producing mines.
100% Unexplored Subsurface
No drilling has ever been completed on the property. All surface and geochemical work indicates live systems with depth extension potential — the entire resource upside remains uncommitted, and Phase I results would be directly value-creating for any incoming investor or operator.
Sierra Madre Occidental Belt
The property sits within the most prolific silver-gold volcanic belt in the Americas — the same region hosting Fresnillo PLC's La Cienega mine (2M+ oz Au produced), the Tayoltita mine (Luismin/Primero Mining), and the 600M tonne Metates deposit (Chesapeake Gold). A favourable regional context for resource discovery.
03

Phase I Exploration Program

Recommended Drilling
~$1.5M
NI 43-101-defined Phase I drill program targeting La Campana and Santa Rita structures. Estimated 10–12 holes at 100–150m depth. Budget per Boily (2008) updated for current costs.
Geophysics
~$250K
IP and magnetic geophysical survey recommended to refine drill targets at depth below mapped vein outcrops, increasing hit probability and optimizing hole placement.
Upside Potential
Open
With 1 km of mapped La Campana strike and two additional showing systems untested at depth, the discovery potential well exceeds the initial Phase I investment.
04

Proposed Transaction

The property is offered to qualified investors and mine developers with the following transaction structures considered:

Option A
Outright Sale
Full acquisition of the mining concessions, geological data, and NI 43-101 report. Ideal for an operator with an existing exploration team in the Sierra Madre region seeking to add a pre-drill, technically characterized asset.
Option B
Earn-In JV
Earn-in arrangement granting majority interest upon completion of defined Phase I exploration milestones. Vendor retains a minority carried interest and net smelter royalty participation after earn-in completion.
Option C
Option Agreement
A paid exploration option providing the right to acquire the asset following a defined Phase I drill campaign window, during which the optionee operates and funds all exploration activity.
