4. HIGHLIGHTS
Gold resource: 300,000 ounce indicated oxide gold resource with 85% extraction in
preliminary leach tests.
Zinc resource : +500,000,000 pound zinc resource with 85.3% extraction in
preliminary leach tests.
Oxide gold and zinc resources open along strike in both directions.
Recent expansion of landholdings with Yamana property option Agreement, 7,000
ha concession total containing 17.5 km of strike length
Sulphide resource open to depth and north and south on strike. Drill Hole CP011
intersected 10% combined lead and zinc, 0.78% copper and good silver and gold
credits over significant width.
Thickness of zone, topography and grade indicate potential for very low cost initial
open pit operation focused on mining the oxide gold resource.
Premier logistics include water source, paved highway and national power grid
within 10 kilometers and good mining work force within one hour of project.
Mining friendly Mexico gives the opportunity to put project into production within a
short time frame.
