SONORAN DESERT COPPER CORPORATION

THE CUATRO HERMANOS PROJECT

Get Started

Copper Project

The Cuatro Hermanos Porphyry Copper Project (the “4H Project”), located in Sonora, Mexico, 185 kilometres southeast of Hermosillo.

The Cuatro Hermanos Copper Project:

  • Is currently an 8- square kilometre, at-surface, copper and molybdenum system with near-term soluble copper (SXEW) production potential.
  • The asset in its entirety versus the current value of PMR, represents tremendous leverage to rising copper and molybdenum prices which are beginning to reflect projected deficits in forward supply.


Note: San Lorenzo is 5,300 ha (total 4H Project is 8,125 ha)

4H Development Plans

  • General Project Exploration

    • Ground survey, mapping and sampling, data modeling

  • New Exploration (add to soluble + sulphide)

    • North/South conglomerate, Cerro San Felipe & San Lorenzo (targeting copper core at Cerro San Felipe)

  • Soluble Resource to Production

    • Confirmations: Cactus, Main/Sulphate & West + New

  • Sulphide Resource

    • Confirmations: Cactus, Main/Sulphate & West + New

  • General

    • • Metallurgy for soluble copper and sulphide recoveries
    • Full spectrum assays for associated by-products
    • PEA, Pre-Feasibility and BFS on soluble copper production model

Soluble (SXEW) Copper - Development Plan

Initial focus is to scale the soluble copper inventory to +100 million tonnes and historical evidence from Phelps Dodge work (USGS Report) indicates the conglomerates alone could contain a considerable amount of soluble copper with a stated inventory of 90 – 200 million tonnes @ +0.40% starting on surface

4H Project Overview:

Concessions

10 concessions totalling 8,125 hectares which contains a large porphyry copper-molybdenum system with surface measurements of at least four kilometres east-west by two kilometres north-south.

Initial exploration

Initial exploration work on the property by companies including Occidental Petroleum (1969), Amoco (1974-1975), Cominco (1981), BHP-Magma (1997) and Phelps Dodge (1998) was limited in overall extent.

Erosion

Erosion has been sufficiently moderate so that a leached oxidized capping of 10 to 60 metres thickness has developed over the primary sulphides.

Mineralization

Secondary supergene chalcocite mineralization is present in a tabular zone at the base of oxidation and the presence of exotic copper mineralization, transported by acid sulphate surface waters into stream gravels

Conglomerate

Conglomerate indicates primary sulphides were oxidized, copper put into solution and acid copper sulphate solutions moved down and laterally.

Copper-molybdenum

Primary porphyry copper-molybdenum mineralization, mainly pyrite, chalcopyrite, and molybdenite, is present in quartz-veinlet stock works, disseminations and breccias associated with high level porphyritic intrusions of quartz.

Mineralization


Mineralization on the 4H Project consists of disseminated porphyry copper-molybdenum mineralization and peripheral exotic copper mineralization. Known centres of porphyry copper-molybdenum mineralization are the Main-Sulfate Zones, Cactus Zone, and the West Zone.

Main Zone


The Main Zone of disseminated copper-molybdenum mineralization is irregular in surface outline, measuring about 700 metres north-south by 300 to 600 in an east-west direction.

Sulfate Zone


The Sulfate Zone of disseminated copper-molybdenum mineralization is about 500 metres north-south by about 200 metres east-west and lies just north of and adjacent to the Main Zone.

Cactus Zone


The Cactus Zone is an area of oxide and sulphide copper-molybdenum mineralization about 300 by 1,000 metres. Based on the drill results, the oxide zone appears to average near 0.48 %Cu, while the underlying hypogene sulphide zone is near 0.44 %Cu and 0.017 %Mo.

West Zone


The West Zone is about 1000 metres north-south and 700 meters east-west and is located about two kilometres west of the Main Zone. It has been tested with about 18 holes; 12 were drilled by Amoco, one by Occidental, one by Cominco, and four by VGM.

North and South Conglomerate Zones


The North and South Conglomerate Zones are comprised of crudely stratified, poorly sorted, polymictic conglomerates of probable Quaternary age, which were deposited on an erosion surface developed over the Cretaceous volcanic stratigraphy.
