Laura Property
The Laura gold project is located approximately 5 km (3 miles) southwest of the Cortez open pit gold mine and approximately 3 km (1.2 miles) west of the +10 million ounce Cortez Hills deposit, both owned by Barrick Gold. In September 2011, Barrick also announced significant new discoveries respectively about 6 km (3.7 miles) and 8 km (5 miles) southeast of Cortez Hills, known as Red Hill and Goldrush. An inferred gold resource of 3.5 million ounces has been outlined at Red Hill with mineralization open in all directions and at Goldrush further south, a drill hole intersected 20.5 m grading 27.8 g/t gold.
The Laura project is 100% controlled by Columbus Gold subject to underlying royalties, however, Sniper Resources can earn an initial 70% interest in the project.
Laura has potential for both epithermal volcanic-hosted, and Carlin-type sediment-hosted gold. The property is underlain by Oligocene Caetano volcanic rocks and lies just to the south of the volcanic/Paleozoic-Upper Plate fault contact. Gold mineralization, both in surface sampling and at depth in drill holes, is hosted in what has been described as a heterolithic "jasperoid breccia", a horizon with clasts of chert-like rock, vein quartz and various altered volcanic lithologies. This unit zone is approximately 40 m (130 ft) thick, strikes north-northeast and dips in ±20° to the east. The breccia horizon is sandwiched between ash-flow tuff and, locally, intrusive felsite.
The first serious exploration program at Laura was apparently conducted by Conquest Explorations Ltd. and Heritage Petroleum Inc. in 1993. Their work consisted of mapping, soil and rock sampling and a 4.5 km (2.8 miles) IP survey. A six-hole drill program totaling 651.7 m (2,135 ft) was completed in December of that year. Anomalous to significant gold was intercepted in several of the holes including 9.1 m of 0.69 g/t (30 ft of 0.020 opt) gold, which has been interpreted to be near a felsite intrusive body.
The nearby discovery of Cortez Hills, and the most recent nearby discoveries at Red Hill and Goldrush, indicate that the Laura Property requires further exploration at depths deep enough to test the Paleozoic rocks, host to the significant deposits in the region.
