Cañadon Largo
Location
By road access, Cañadon Largo (7,986ha) is located 20km E of Sierra Blanca.
Ownership
100% Mariana, with 1.5% NSR to IAMGOLD
Previous Exploration
Limited rock chip sampling by IAMGOLD.
Geological Setting
Low sulphidation epithermal vein strongly anomalous in gold, silver and pathfinder elements. Silicification, quartz veins and breccias occur along a 1.7km trend. Vein widths of up to 4m are reported with rock chip assays up to 1.4 g/t Au and 238 g/t Ag. Silicified zones reach widths of up to 8m.
Exploration by Mariana
In late 2006, early 2007, Mariana drilled 4 diamond holes for a total of 472m. Holes CL 1 and CL 3 intersected strong vein structures, but gold and silver assays were low. However, hole CL 1 intersected significant pathfinders (Hg to 25 ppm, Sb to 242 ppm, and As to 2720 ppm) between 77.9m and 95.7m suggesting shallow epithermal depth. Mariana believes potential for higher grades could remain at depth.
In view of the encouraging results the Company is currently reviewing exploration options at Cañadon Largo which may include seeking a Joint Venture partner.
