Project Rio at a Glance
Rio Babasac Placer Mining Concession, Imuris, Sonora — complete asset summary
Background: The concession was first identified as an investment opportunity in March 2007 by a Vancouver-based corporate broker, and presented to the current beneficial owner — a Dubai-based UHNWI. Following expert consultation, a senior US law firm was engaged as legal counsel and a global co-investor search commenced. [Principal identity disclosed post-NDA]
In January 2008, Merrill Lynch New York (Latin & Central America Natural Resources team) conducted due diligence and offered to fund all exploration costs for 25% of the concession, with a minimum $100M PIK loan facility for production and lead IPO sponsorship. This deal collapsed due to the Global Financial Crisis in late 2008.
On 24 August 2009, a newly incorporated Mexican mining entity became the 100% sole owner of the concession, held through UAE and BVI holding vehicles. This proposal was circulated January 2011.
Property Description & Geological Context
Sonora's "Canyon of Gold" — Mexico's most prolific placer gold corridor
Location: The concession sits on the dry bed of the Babasac River in Imuris, Sonora — within the "Cañada el Oro" (Canyon of Gold). Gold has been mined here for centuries, predominantly by hand.
Access: 2 hours by car from Hermosillo via Federal Highway 15. ~40 miles south of the US/Mexico border at Nogales. Site was verified accessible by field team in February 2010.
Terrain: Flat dry riverbed — ideal for hydraulic dredge extraction, the lowest-cost, highest-efficiency method for alluvial placer deposits. No blasting, no open-pit — just dredging.
Why Sonora Matters
Sonora is Mexico's "Golden Triangle" — one of the world's highest-density gold-producing regions. The Babasac concession sits at its centre. Drilling confirms substantial unextracted placer gold, consistent with the low extraction penetration typical of the region's artisanal history.
Formation belongs to the Baucarit Conglomerate (Miocene) of the Sierra Madre Occidental — the classic host rock for alluvial placer gold in Sonora. Water table at 35 ft depth.

Corporate & Title Structure
Clean title confirmed by Mexican Public Registry of Mining — January 2011
Legal Confirmation: A formal legal opinion from a leading Mexican mining law firm confirms the concession is recorded with the Public Registry of Mining (Mexico City) as fully owned, free and clear, by the operating entity. [Law firm name and opinion letter disclosed post-NDA]
Management: Two named individuals hold unlimited powers of attorney on behalf of the operating entity — a Sole Administrator and a General Manager, both UAE-based. [Names disclosed post-NDA]
All property fees and taxes are fully paid as of the document date. No encumbrances, liens, or legal disputes disclosed.
Due Diligence Note
The ownership chain runs through a UAE entity (90%) and a BVI entity (10%) into a fully registered Mexican mining corporation. Acquisition can be structured as either a share purchase of the Mexican entity or an acquisition of the holding companies. Full corporate details, entity names, and registered addresses are provided upon NDA execution.
Permitting Status
SEMARNAT, CONAGUA, Mexican Mining Law — all filed and granted
SEMARNAT requires an Environmental Impact Assessment and Environmental Risk Study before any mining activity commences. Both were filed and approved under the "Proyecto de Exploración Río Babasac" (Sep–Dec 2010).
CONAGUA (water rights) — critical for placer washing operations. Permit submitted and granted.
No ejido (communal land) claims in the core drilling area. The eastern portion contains ejido ranches, but the primary mineralised zone (yellow band in field maps) is unencumbered.
Note: Moving to production will require new production permits and an expanded EIA. Mexico's mining law is generally investor-friendly with broad foreign ownership rights and constitutional protections.
Mexico Economic Environment
Economist Intelligence Unit Country Report — January 2011 (included in proposal)
Gold Price Context: The proposal uses $1,300/oz (2011 market price). As of May 2026, gold trades at approximately $3,300/oz — 2.5× the valuation basis in this document. At current prices, proven reserve gross value rises from $1.157B to approximately $2.94B, and the LOM indicated value from $41.6B to ~$105B.
Mexico as a mining jurisdiction: Mexico is among the world's top 5 gold producers. Sonora has a long history of commercial mining — Peñoles, Newmont, First Majestic Silver all operate in the region. Mexico's Mining Law grants broad rights to concession holders including foreign-owned entities, with constitutional protections for subsurface resource rights.
Investment Risk Assessment
Principal risks to be assessed by any acquirer or investor
Pre-Close Checklist
Why This Opportunity is Compelling
A considered framing for the qualified investor or acquirer
1. Proven Ground
The Sonora Golden Triangle is not speculative — it is one of the most documented gold-bearing corridors in the Americas. Eight boreholes confirm economically significant gold concentration at every depth interval. No exploration risk in the drilled zone.
2. Gold Price Tailwind
Every figure in this document is based on $1,300/oz. At $3,300/oz current market, the same asset is 2.5× more valuable. A buyer today acquires at a structurally discounted cost-basis in a sustained gold bull cycle.
3. Dredge-Optimal Terrain
Flat dry riverbed = hydraulic dredge extraction — the lowest-capex, highest-throughput method for alluvial placer. Materially lower capex than underground or open-pit hard rock mining of equivalent grade.
Scale of Opportunity: 9.8M m² along a 10 km proven gold river bed is exceptional. The 8 drilled holes cover only the northeast quadrant. The 31.98M oz indicated reserve extrapolates the confirmed drill density across the full concession — standard placer methodology.
Institutional Precedent: Merrill Lynch's Latin America Natural Resources team — post-GFC, one of the most rigorous commodity DD teams globally — cleared full due diligence and offered $100M+ PIK plus IPO mandate. It failed due to the GFC, not geology or title.
Acquisition pathways: (a) direct operator/developer, (b) royalty acquisition, (c) JV with a listed mining company, (d) reverse merger into a TSX-V, ASX, or AIM listing vehicle — fully consistent with the Merrill Lynch IPO pathway originally contemplated.
