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
- New Exploration (add to soluble + sulphide)
- Soluble Resource to Production
- Sulphide Resource

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.
